Standalone version in zapret-winws folder !!
|
||||
From this folder winws can be started only from cygwin shell.
|
||||
|
||||
Cygwin refuses to start winws if a copy of cygwin1.dll is present !
|
||||
|
||||
How to get win7 and winws compatible version of cygwin :
|
||||
|
||||
curl -O https://www.cygwin.com/setup-x86_64.exe
|
||||
setup-x86_64.exe --allow-unsupported-windows --no-verify --site http://ctm.crouchingtigerhiddenfruitbat.org/pub/cygwin/circa/64bit/2024/01/30/231215

## Supported versions
|
||||
|
||||
FreeBSD 11.x+ , OpenBSD 6.x+, partially MacOS Sierra+
|
||||
|
||||
Older versions may work or not.
|
||||
|
||||
## BSD features
|
||||
|
||||
BSD does not have NFQUEUE. Similar mechanism - divert sockets. In BSD compiling
|
||||
the source from nfq directory result in `dvtws` binary instead of `nfqws`.
|
||||
`dvtws` shares most of the code with `nfqws` and offers almost identical
|
||||
parameters.
|
||||
|
||||
FreeBSD has 3 firewalls: IPFilter, ipfw and Packet Filter (PF). OpenBSD has
|
||||
only PF.
|
||||
|
||||
To compile sources:
|
||||
|
||||
- FreeBSD: `make`
|
||||
- OpenBSD: `make bsd`
|
||||
- MacOS: `make mac`
|
||||
|
||||
Compile all programs:
|
||||
```
|
||||
make -C /opt/zapret
|
||||
```
|
||||
|
||||
Divert sockets are internal type sockets in the BSD kernel. They have no
|
||||
relation to network addresses or network packet exchange. They are identified
|
||||
by a port number `1..65535`. Its like queue number in NFQUEUE. Traffic can be
|
||||
diverted to a divert socket using firewall rule. If nobody listens on the
|
||||
specified divert port packets are dropped. Its similar to NFQUEUE without
|
||||
`--queue-bypass`.
|
||||
|
||||
`ipset/*.sh` scripts work with ipfw lookup tables if ipfw is present.
|
||||
|
||||
ipfw table is analog to linux `ipset`. Unlike ipsets ipfw tables share v4 an v6
|
||||
addresses and subnets.
|
||||
|
||||
- If ipfw is absent scripts check LISTS_RELOAD config variable.
|
||||
- If its present then scripts execute a command from LISTS_RELOAD.
|
||||
- If LISTS_RELOAD=- scripts do not load tables even if ipfw exists.
|
||||
|
||||
PF can load ip tables from a file. To use this feature with `ipset/*.sh` scripts disable gzip file creation
|
||||
using `GZIP_LISTS=0` directive in the `/opt/zapret/config` file.
|
||||
|
||||
BSD kernel doesn't implement splice syscall. tpws uses regular recv/send
|
||||
operations with data copying to user space. Its slower but not critical.
|
||||
|
||||
`tpws` uses nonblocking sockets with linux specific epoll feature. In BSD systems
|
||||
epoll is emulated by epoll-shim library on top of kqueue.
|
||||
|
||||
`dvtws` uses some programming HACKs, assumptions and knowledge of discovered
|
||||
bugs and limitations. BSD systems have many limitations, version specific
|
||||
features and bugs in low level networking, especially for ipv6. Many years have
|
||||
passed but BSD code still has 15-20 year artificial limiters in the code. `dvtws`
|
||||
uses additinal divert socket(s) for layer 3 packet injection if raw sockets do
|
||||
not allow it. It works for the moment but who knows. Such a usage is not very
|
||||
documented.
|
||||
|
||||
`mdig` and `ip2net` are fully compatible with BSD.
|
||||
|
||||
|
||||
## FreeBSD
|
||||
|
||||
Divert sockets require special kernel module `ipdivert`.
|
||||
Write the following to config files:
|
||||
|
||||
`/boot/loader.conf` (create if absent):
|
||||
```
|
||||
ipdivert_load="YES"
|
||||
net.inet.ip.fw.default_to_accept=1
|
||||
```
|
||||
|
||||
`/etc/rc.conf`:
|
||||
```
|
||||
firewall_enable="YES"
|
||||
firewall_script="/etc/rc.firewall.my"
|
||||
```
|
||||
|
||||
`/etc/rc.firewall.my`:
|
||||
```
|
||||
ipfw -q -f flush
|
||||
```
|
||||
|
||||
Later you will add ipfw commands to `/etc/rc.firewall.my` to be reapplied after reboot.
|
||||
You can also run zapret daemons from there. Start them with `--daemon` options, for example
|
||||
```
|
||||
pkill ^dvtws$
|
||||
/opt/zapret/nfq/dvtws --port=989 --daemon --dpi-desync=split2
|
||||
```
|
||||
|
||||
To restart firewall and daemons run : `/etc/rc.d/ipfw restart`
|
||||
|
||||
Assume `LAN="em1"`, `WAN="em0"`.
|
||||
|
||||
`tpws` transparent mode quick start.
|
||||
|
||||
For all traffic:
|
||||
```
|
||||
ipfw delete 100
|
||||
ipfw add 100 fwd 127.0.0.1,988 tcp from me to any 80,443 proto ip4 xmit em0 not uid daemon
|
||||
ipfw add 100 fwd ::1,988 tcp from me to any 80,443 proto ip6 xmit em0 not uid daemon
|
||||
ipfw add 100 fwd 127.0.0.1,988 tcp from any to any 80,443 proto ip4 recv em1
|
||||
ipfw add 100 fwd ::1,988 tcp from any to any 80,443 proto ip6 recv em1
|
||||
/opt/zapret/tpws/tpws --port=988 --user=daemon --bind-addr=::1 --bind-addr=127.0.0.1
|
||||
```
|
||||
|
||||
Process only table zapret with the exception of table nozapret:
|
||||
```
|
||||
ipfw delete 100
|
||||
ipfw add 100 allow tcp from me to table\(nozapret\) 80,443
|
||||
ipfw add 100 fwd 127.0.0.1,988 tcp from me to table\(zapret\) 80,443 proto ip4 xmit em0 not uid daemon
|
||||
ipfw add 100 fwd ::1,988 tcp from me to table\(zapret\) 80,443 proto ip6 xmit em0 not uid daemon
|
||||
ipfw add 100 allow tcp from any to table\(nozapret\) 80,443 recv em1
|
||||
ipfw add 100 fwd 127.0.0.1,988 tcp from any to any 80,443 proto ip4 recv em1
|
||||
ipfw add 100 fwd ::1,988 tcp from any to any 80,443 proto ip6 recv em1
|
||||
/opt/zapret/tpws/tpws --port=988 --user=daemon --bind-addr=::1 --bind-addr=127.0.0.1
|
||||
```
|
||||
|
||||
Tables zapret, nozapret, ipban are created by `ipset/*.sh` scripts the same way as in Linux.
|
||||
Its a good idea to update tables periodically:
|
||||
```
|
||||
crontab -e
|
||||
```
|
||||
|
||||
Write the line:
|
||||
```
|
||||
0 12 */2 * * /opt/zapret/ipset/get_config.sh
|
||||
```
|
||||
|
||||
When using `ipfw`, `tpws` does not require special permissions for transparent
|
||||
mode. However without root its not possible to bind to ports less than 1024 and
|
||||
change UID/GID. Without changing UID tpws will run into recursive loop, and
|
||||
that's why its necessary to write ipfw rules with the right UID. Redirecting to
|
||||
ports greater than or equal to 1024 is dangerous. If tpws is not running any
|
||||
unprivileged process can listen to that port and intercept traffic.
|
||||
|
||||
### `dvtws` quick start
|
||||
|
||||
For all traffic:
|
||||
```
|
||||
ipfw delete 100
|
||||
ipfw add 100 divert 989 tcp from any to any 80,443 out not diverted not sockarg xmit em0
|
||||
# required for autottl mode only
|
||||
ipfw add 100 divert 989 tcp from any 80,443 to any tcpflags syn,ack in not diverted not sockarg recv em0
|
||||
/opt/zapret/nfq/dvtws --port=989 --dpi-desync=split2
|
||||
```
|
||||
|
||||
Process only table zapret with the exception of table nozapret:
|
||||
```
|
||||
ipfw delete 100
|
||||
ipfw add 100 allow tcp from me to table\(nozapret\) 80,443
|
||||
ipfw add 100 divert 989 tcp from any to table\(zapret\) 80,443 out not diverted not sockarg xmit em0
|
||||
# required for autottl mode only
|
||||
ipfw add 100 divert 989 tcp from table\(zapret\) 80,443 to any tcpflags syn,ack in not diverted not sockarg recv em0
|
||||
/opt/zapret/nfq/dvtws --port=989 --dpi-desync=split2
|
||||
```
|
||||
|
||||
Reinjection loop avoidance. FreeBSD artificially ignores sockarg for ipv6 in
|
||||
the kernel. This limitation is coming from the ipv6 early age. Code is still in
|
||||
"testing" state. 10-20 years. Everybody forgot about it. `dvtws` sends ipv6
|
||||
forged frames using another divert socket (HACK). they can be filtered out
|
||||
using 'diverted'. ipv4 frames are filtered using 'sockarg'.
|
||||
|
||||
### PF in FreeBSD
|
||||
|
||||
The setup is similar to OpenBSD, but there are important nuances.
|
||||
1. PF support is disabled by default in FreeBSD. Use parameter `--enable-pf`.
|
||||
2. It's not possible to redirect to `::1`. Need to redirect to the link-local
|
||||
address of the incoming interface. Look for fe80:... address in ifconfig and
|
||||
use it for redirection target.
|
||||
3. pf.conf syntax is a bit different from OpenBSD.
|
||||
4. How to set maximum table size : sysctl net.pf.request_maxcount=2000000
|
||||
5. `divert-to` is broken. Loop avoidance scheme does not work.
|
||||
This makes `dvtws` unusable with pf.
|
||||
Someone posted kernel patch but 14-RELEASE is still broken.
|
||||
|
||||
`/etc/pf.conf`:
|
||||
```
|
||||
rdr pass on em1 inet6 proto tcp to port {80,443} -> fe80::31c:29ff:dee2:1c4d port 988
|
||||
rdr pass on em1 inet proto tcp to port {80,443} -> 127.0.0.1 port 988
|
||||
```
|
||||
|
||||
Then:
|
||||
```
|
||||
/opt/zapret/tpws/tpws --port=988 --enable-pf --bind-addr=127.0.0.1 --bind-iface6=em1 --bind-linklocal=force
|
||||
```
|
||||
|
||||
Its not clear how to do rdr-to outgoing traffic. I could not make route-to
|
||||
scheme work.
|
||||
|
||||
|
||||
### `pfsense`
|
||||
|
||||
`pfsense` is based on FreeBSD. Binaries from `binaries/freebsd-x64` are
|
||||
compiled in FreeBSD 11 and should work. Use `install_bin.sh`. pfsense uses pf
|
||||
firewall which does not support divert. Fortunately ipfw and ipdivert modules
|
||||
are present and can be kldload-ed. In older versions it's also necessary to
|
||||
change firewall order using sysctl commands. In newer versions those sysctl
|
||||
parameters are absent but the system behaves as required without them.
|
||||
Sometimes pf may limit `dvtws` abilities. It scrubs ip fragments disabling `dvtws`
|
||||
ipfrag2 desync mode.
|
||||
|
||||
There's autostart script example in `init.d/pfsense`. It should be placed to
|
||||
`/usr/local/etc/rc.d` and edited. Write your ipfw rules and daemon start
|
||||
commands. Because git is absent the most convinient way to copy files is ssh.
|
||||
curl is present by default.
|
||||
|
||||
Copy zip with zapret files to `/opt` and unpack there as it's done in other
|
||||
systems. In this case run `dvtws` as `/opt/zapret/nfq/dvtws`. Or just copy
|
||||
`dvtws` to `/usr/local/sbin`. As you wish. `ipset` scripts are working, cron is
|
||||
present. It's possible to renew lists.
|
||||
|
||||
If you dont like poverty of default repos its possible to enable FreeBSD repo.
|
||||
Change `no` to `yes` in `/usr/local/etc/pkg/repos/FreeBSD.conf` and `/usr/local/etc/pkg/repos/pfSense.conf`.
|
||||
Then it becomes possible to install all the required software including git to download
|
||||
zapret from github directly.
|
||||
|
||||
|
||||
`/usr/local/etc/rc.d/zapret.sh` (chmod 755)
|
||||
```
|
||||
#!/bin/sh
|
||||
|
||||
kldload ipfw
|
||||
kldload ipdivert
|
||||
|
||||
# for older pfsense versions. newer do not have these sysctls
|
||||
sysctl net.inet.ip.pfil.outbound=ipfw,pf
|
||||
sysctl net.inet.ip.pfil.inbound=ipfw,pf
|
||||
sysctl net.inet6.ip6.pfil.outbound=ipfw,pf
|
||||
sysctl net.inet6.ip6.pfil.inbound=ipfw,pf
|
||||
|
||||
ipfw delete 100
|
||||
ipfw add 100 divert 989 tcp from any to any 80,443 out not diverted not sockarg xmit em0
|
||||
pkill ^dvtws$
|
||||
dvtws --daemon --port 989 --dpi-desync=split2
|
||||
|
||||
# required for newer pfsense versions (2.6.0 tested) to return ipfw to functional state
|
||||
pfctl -d ; pfctl -e
|
||||
```
|
||||
|
||||
I could not make tpws work from ipfw. Looks like there's some conflict between
|
||||
two firewalls. Only PF redirection works. PF does not allow to freely add and
|
||||
delete rules. Only anchors can be reloaded. To make an anchor work it must be
|
||||
referred from the main ruleset. But its managed by pfsense scripts.
|
||||
|
||||
One possible solution would be to modify `/etc/inc/filter.inc` as follows:
|
||||
```
|
||||
.................
|
||||
/* MOD */
|
||||
$natrules .= "# ZAPRET redirection\n";
|
||||
$natrules .= "rdr-anchor \"zapret\"\n";
|
||||
|
||||
$natrules .= "# TFTP proxy\n";
|
||||
$natrules .= "rdr-anchor \"tftp-proxy/*\"\n";
|
||||
.................
|
||||
```
|
||||
|
||||
Write the anchor code to `/etc/zapret.anchor`:
|
||||
```
|
||||
rdr pass on em1 inet proto tcp to port {80,443} -> 127.0.0.1 port 988
|
||||
rdr pass on em1 inet6 proto tcp to port {80,443} -> fe80::20c:29ff:5ae3:4821 port 988
|
||||
```
|
||||
Replace `fe80::20c:29ff:5ae3:4821` with your link local address of the LAN
|
||||
interface or remove the line if ipv6 is not needed.
|
||||
|
||||
Autostart `/usr/local/etc/rc.d/zapret.sh`:
|
||||
```
|
||||
pfctl -a zapret -f /etc/zapret.anchor
|
||||
pkill ^tpws$
|
||||
tpws --daemon --port=988 --enable-pf --bind-addr=127.0.0.1 --bind-iface6=em1 --bind-linklocal=force --split-http-req=method --split-pos=2
|
||||
```
|
||||
|
||||
After reboot check that anchor is created and referred from the main ruleset:
|
||||
```
|
||||
[root@pfSense /]# pfctl -s nat
|
||||
no nat proto carp all
|
||||
nat-anchor "natearly/*" all
|
||||
nat-anchor "natrules/*" all
|
||||
...................
|
||||
no rdr proto carp all
|
||||
rdr-anchor "zapret" all
|
||||
rdr-anchor "tftp-proxy/*" all
|
||||
rdr-anchor "miniupnpd" all
|
||||
[root@pfSense /]# pfctl -s nat -a zapret
|
||||
rdr pass on em1 inet proto tcp from any to any port = http -> 127.0.0.1 port 988
|
||||
rdr pass on em1 inet proto tcp from any to any port = https -> 127.0.0.1 port 988
|
||||
rdr pass on em1 inet6 proto tcp from any to any port = http -> fe80::20c:29ff:5ae3:4821 port 988
|
||||
rdr pass on em1 inet6 proto tcp from any to any port = https -> fe80::20c:29ff:5ae3:4821 port 988
|
||||
```
|
||||
|
||||
Also there's a way to add redirect in the pfsense UI and start `tpws` from cron using `@reboot` prefix.
|
||||
This way avoids modification of pfsense code.
|
||||
|
||||
## OpenBSD
|
||||
|
||||
In OpenBSD default `tpws` bind is ipv6 only. To bind to ipv4 specify
|
||||
`--bind-addr=0.0.0.0`.
|
||||
|
||||
Use `--bind-addr=0.0.0.0 --bind-addr=::` to achieve the same default bind as in
|
||||
others OSes.
|
||||
|
||||
`tpws` for forwarded traffic only :
|
||||
|
||||
`/etc/pf.conf`:
|
||||
```
|
||||
pass in quick on em1 inet proto tcp to port {80,443} rdr-to 127.0.0.1 port 988
|
||||
pass in quick on em1 inet6 proto tcp to port {80,443} rdr-to ::1 port 988
|
||||
```
|
||||
|
||||
Then:
|
||||
```
|
||||
pfctl -f /etc/pf.conf
|
||||
tpws --port=988 --user=daemon --bind-addr=::1 --bind-addr=127.0.0.1
|
||||
```
|
||||
|
||||
Its not clear how to do rdr-to outgoing traffic. I could not make route-to
|
||||
scheme work. rdr-to support is done using /dev/pf, that's why transparent mode
|
||||
requires root.
|
||||
|
||||
`dvtws` for all traffic:
|
||||
|
||||
`/etc/pf.conf`:
|
||||
```
|
||||
pass in quick on em0 proto tcp from port {80,443} flags SA/SA divert-packet port 989 no state
|
||||
pass in quick on em0 proto tcp from port {80,443} no state
|
||||
pass out quick on em0 proto tcp to port {80,443} divert-packet port 989
|
||||
```
|
||||
|
||||
Then:
|
||||
```
|
||||
pfctl -f /etc/pf.conf
|
||||
./dvtws --port=989 --dpi-desync=split2
|
||||
```
|
||||
|
||||
`dwtws` only for table zapret with the exception of table nozapret :
|
||||
|
||||
`/etc/pf.conf`:
|
||||
```
|
||||
set limit table-entries 2000000
|
||||
table <zapret> file "/opt/zapret/ipset/zapret-ip.txt"
|
||||
table <zapret-user> file "/opt/zapret/ipset/zapret-ip-user.txt"
|
||||
table <nozapret> file "/opt/zapret/ipset/zapret-ip-exclude.txt"
|
||||
pass out quick on em0 inet proto tcp to <nozapret> port {80,443}
|
||||
pass in quick on em0 inet proto tcp from <zapret> port {80,443} flags SA/SA divert-packet port 989 no state
|
||||
pass in quick on em0 inet proto tcp from <zapret> port {80,443} no state
|
||||
pass out quick on em0 inet proto tcp to <zapret> port {80,443} divert-packet port 989 no state
|
||||
pass in quick on em0 inet proto tcp from <zapret-user> port {80,443} flags SA/SA divert-packet port 989 no state
|
||||
pass in quick on em0 inet proto tcp from <zapret-user> port {80,443} no state
|
||||
pass out quick on em0 inet proto tcp to <zapret-user> port {80,443} divert-packet port 989 no state
|
||||
table <zapret6> file "/opt/zapret/ipset/zapret-ip6.txt"
|
||||
table <zapret6-user> file "/opt/zapret/ipset/zapret-ip-user6.txt"
|
||||
table <nozapret6> file "/opt/zapret/ipset/zapret-ip-exclude6.txt"
|
||||
pass out quick on em0 inet6 proto tcp to <nozapret6> port {80,443}
|
||||
pass in quick on em0 inet6 proto tcp from <zapret6> port {80,443} flags SA/SA divert-packet port 989 no state
|
||||
pass in quick on em0 inet6 proto tcp from <zapret6> port {80,443} no state
|
||||
pass out quick on em0 inet6 proto tcp to <zapret6> port {80,443} divert-packet port 989 no state
|
||||
pass in quick on em0 inet6 proto tcp from <zapret6-user> port {80,443} flags SA/SA divert-packet port 989 no state
|
||||
pass in quick on em0 inet6 proto tcp from <zapret6-user> port {80,443} no state
|
||||
pass out quick on em0 inet6 proto tcp to <zapret6-user> port {80,443} divert-packet port 989 no state
|
||||
```
|
||||
|
||||
Then:
|
||||
```
|
||||
pfctl -f /etc/pf.conf
|
||||
./dvtws --port=989 --dpi-desync=split2
|
||||
```
|
||||
|
||||
divert-packet automatically adds the reverse rule. By default also incoming
|
||||
traffic will be passwed to `dvtws`. This is highly undesired because it is waste
|
||||
of cpu resources and speed limiter. The trick with "no state" and "in" rules
|
||||
allows to bypass auto reverse rule.
|
||||
|
||||
`dvtws` in OpenBSD sends all fakes through a divert socket because raw sockets
|
||||
have critical artificial limitations. Looks like pf automatically prevent
|
||||
reinsertion of diverted frames. Loop problem does not exist.
|
||||
|
||||
OpenBSD forcibly recomputes tcp checksum after divert. Thats why most likely
|
||||
dpi-desync-fooling=badsum will not work. `dvtws` will warn if you specify this
|
||||
parameter.
|
||||
|
||||
`ipset` scripts do not reload PF by default. To enable reload specify command in
|
||||
`/opt/zapret/config`:
|
||||
```
|
||||
LISTS_RELOAD="pfctl -f /etc/pf.conf"
|
||||
```
|
||||
|
||||
Newer `pfctl` versions can reload tables only:
|
||||
```
|
||||
pfctl -Tl -f /etc/pf.conf
|
||||
```
|
||||
|
||||
But OpenBSD 6.8 `pfctl` is old enough and does not support that. Newer FreeBSD do.
|
||||
|
||||
Don't forget to disable gzip compression:
|
||||
```
|
||||
GZIP_LISTS=0
|
||||
```
|
||||
|
||||
If some list files do not exist and have references in pf.conf it leads to
|
||||
error. You need to exclude those tables from pf.conf and referencing them
|
||||
rules. After configuration is done you can put `ipset` script:
|
||||
```
|
||||
crontab -e
|
||||
```
|
||||
|
||||
Then write the line:
|
||||
```
|
||||
0 12 */2 * * /opt/zapret/ipset/get_config.sh
|
||||
```
|
||||
|
||||
## MacOS
|
||||
|
||||
Initially, the kernel of this OS was based on BSD. That's why it is still BSD
|
||||
but a lot was modified by Apple. As usual a mass commercial project priorities
|
||||
differ from their free counterparts. Apple guys do what they want.
|
||||
|
||||
MacOS used to have ipfw but it was removed later and replaced by PF. It looks
|
||||
like divert sockets are internally replaced with raw. Its possible to request a
|
||||
divert socket but it behaves exactly as raw socket with all its BSD inherited +
|
||||
apple specific bugs and feature. The fact is that divert-packet in
|
||||
`/etc/pf.conf` does not work. pfctl binary does not contain the word `divert`.
|
||||
|
||||
`dvtws` does compile but is useless.
|
||||
|
||||
After some efforts `tpws` works. Apple has removed some important stuff from
|
||||
their newer SDKs (DIOCNATLOOK) making them undocumented and unsupported.
|
||||
|
||||
With important definitions copied from an older SDK it was possible to make
|
||||
transparent mode working again. But this is not guaranteed to work in the
|
||||
future versions.
|
||||
|
||||
Another MacOS unique feature is root requirement while polling `/dev/pf`.
|
||||
|
||||
By default tpws drops root. Its necessary to specify `--user=root` to stay with
|
||||
root.
|
||||
|
||||
In other aspects PF behaves very similar to FreeBSD and shares the same pf.conf
|
||||
syntax.
|
||||
|
||||
In MacOS redirection works both for passthrough and outgoing traffic. Outgoing
|
||||
redirection requires route-to rule. Because tpws is forced to run as root to
|
||||
avoid loop its necessary to exempt root from the redirection. That's why DPI
|
||||
bypass will not work for local requests from root.
|
||||
|
||||
If you do ipv6 routing you have to get rid of "secured" ipv6 address
|
||||
assignment.
|
||||
|
||||
"secured" addresses are designed to be permanent and not related to the MAC
|
||||
address.
|
||||
|
||||
And they really are. Except for link-locals.
|
||||
|
||||
If you just reboot the system link-locals will not change. But next day they
|
||||
will change.
|
||||
|
||||
Not necessary to wait so long. Just change the system time to tomorrow and reboot.
|
||||
Link-locals will change (at least they change in vmware guest). Looks like its a kernel bug.
|
||||
Link locals should not change. Its useless and can be harmful. Cant use LL as a gateway.
|
||||
|
||||
The easiest solution is to disable "secured" addresses.
|
||||
|
||||
Outgoing connections prefer randomly generated temporary addressesas like in other systems.
|
||||
|
||||
Put the string `net.inet6.send.opmode=0` to `/etc/sysctl.conf`. If not present
|
||||
- create it.
|
||||
|
||||
Then reboot the system.
|
||||
|
||||
If you dont like this solution you can assign an additional static ipv6 address
|
||||
from `fc00::/7` range with `/128` prefix to your LAN interface and use it as
|
||||
the gateway address.
|
||||
|
||||
`tpws` transparent mode only for outgoing connections.
|
||||
|
||||
`/etc/pf.conf`:
|
||||
```
|
||||
rdr pass on lo0 inet proto tcp from !127.0.0.0/8 to any port {80,443} -> 127.0.0.1 port 988
|
||||
rdr pass on lo0 inet6 proto tcp from !::1 to any port {80,443} -> fe80::1 port 988
|
||||
pass out route-to (lo0 127.0.0.1) inet proto tcp from any to any port {80,443} user { >root }
|
||||
pass out route-to (lo0 fe80::1) inet6 proto tcp from any to any port {80,443} user { >root }
|
||||
```
|
||||
|
||||
Then:
|
||||
```
|
||||
pfctl -ef /etc/pf.conf
|
||||
/opt/zapret/tpws/tpws --user=root --port=988 --bind-addr=127.0.0.1 --bind-iface6=lo0 --bind-linklocal=force
|
||||
```
|
||||
|
||||
`tpws` transparent mode for both passthrough and outgoing connections. en1 - LAN.
|
||||
|
||||
```
|
||||
ifconfig en1 | grep fe80
|
||||
inet6 fe80::bbbb:bbbb:bbbb:bbbb%en1 prefixlen 64 scopeid 0x8
|
||||
```
|
||||
|
||||
`/etc/pf.conf`:
|
||||
```
|
||||
rdr pass on en1 inet proto tcp from any to any port {80,443} -> 127.0.0.1 port 988
|
||||
rdr pass on en1 inet6 proto tcp from any to any port {80,443} -> fe80::bbbb:bbbb:bbbb:bbbb port 988
|
||||
rdr pass on lo0 inet proto tcp from !127.0.0.0/8 to any port {80,443} -> 127.0.0.1 port 988
|
||||
rdr pass on lo0 inet6 proto tcp from !::1 to any port {80,443} -> fe80::1 port 988
|
||||
pass out route-to (lo0 127.0.0.1) inet proto tcp from any to any port {80,443} user { >root }
|
||||
pass out route-to (lo0 fe80::1) inet6 proto tcp from any to any port {80,443} user { >root }
|
||||
```
|
||||
|
||||
Then:
|
||||
```
|
||||
pfctl -ef /etc/pf.conf
|
||||
/opt/zapret/tpws/tpws --user=root --port=988 --bind-addr=127.0.0.1 --bind-iface6=lo0 --bind-linklocal=force --bind-iface6=en1 --bind-linklocal=force
|
||||
```
|
||||
|
||||
Build from source : `make -C /opt/zapret mac`
|
||||
|
||||
`ipset/*.sh` scripts work.
|
||||
|
||||
|
||||
### MacOS easy install
|
||||
|
||||
`install_easy.sh` supports MacOS
|
||||
|
||||
Shipped precompiled binaries are built for 64-bit MacOS with
|
||||
`-mmacosx-version-min=10.8` option. They should run on all supported MacOS
|
||||
versions. If no - its easy to build your own. Running `make` automatically
|
||||
installs developer tools.
|
||||
|
||||
**WARNING**:
|
||||
**Internet sharing is not supported!**
|
||||
|
||||
Routing is supported but only manually configured through PF. If you enable
|
||||
internet sharing tpws stops functioning. When you disable internet sharing you
|
||||
may lose web site access.
|
||||
|
||||
To fix:
|
||||
```
|
||||
pfctl -f /etc/pf.conf
|
||||
```
|
||||
|
||||
If you need internet sharing use `tpws` socks mode.
|
||||
|
||||
`launchd` is used for autostart (`/Library/LaunchDaemons/zapret.plist`)
|
||||
|
||||
Control script: `/opt/zapret/init.d/macos/zapret`
|
||||
|
||||
The following commands fork with both tpws and firewall (if `INIT_APPLY_FW=1` in config)
|
||||
```
|
||||
/opt/zapret/init.d/macos/zapret start
|
||||
/opt/zapret/init.d/macos/zapret stop
|
||||
/opt/zapret/init.d/macos/zapret restart
|
||||
```
|
||||
|
||||
Work with `tpws` only:
|
||||
```
|
||||
/opt/zapret/init.d/macos/zapret start-daemons
|
||||
/opt/zapret/init.d/macos/zapret stop-daemons
|
||||
/opt/zapret/init.d/macos/zapret restart-daemons
|
||||
```
|
||||
|
||||
Work with PF only:
|
||||
```
|
||||
/opt/zapret/init.d/macos/zapret start-fw
|
||||
/opt/zapret/init.d/macos/zapret stop-fw
|
||||
/opt/zapret/init.d/macos/zapret restart-fw
|
||||
```
|
||||
|
||||
Reloading PF tables:
|
||||
```
|
||||
/opt/zapret/init.d/macos/zapret reload-fw-tables
|
||||
```
|
||||
|
||||
Installer configures `LISTS_RELOAD` in the config so `ipset *.sh` scripts
|
||||
automatically reload PF tables. Installer creates cron job for `ipset
|
||||
/get_config.sh`, as in OpenWRT.
|
||||
|
||||
start-fw script automatically patches `/etc/pf.conf` inserting there `zapret`
|
||||
anchors. Auto patching requires pf.conf with apple anchors preserved. If your
|
||||
`pf.conf` is highly customized and patching fails you will see the warning. Do
|
||||
not ignore it.
|
||||
|
||||
In that case you need to manually insert "zapret" anchors to your `pf.conf`
|
||||
(keeping the right rule type ordering):
|
||||
```
|
||||
rdr-anchor "zapret"
|
||||
anchor "zapret"
|
||||
unistall_easy.sh unpatches pf.conf
|
||||
```
|
||||
start-fw creates 3 anchor files in `/etc/pf.anchors` :
|
||||
zapret,zapret-v4,zapret-v6.
|
||||
|
||||
- Last 2 are referenced by anchor `zapret`.
|
||||
- Tables `nozapret`,`nozapret6` belong to anchor `zapret`.
|
||||
- Tables `zapret`,`zapret-user` belong to anchor `zapret-v4`.
|
||||
- Tables `zapret6`,`apret6-user` belong to anchor `zapret-v6`.
|
||||
|
||||
If an ip version is disabled then corresponding anchor is empty and is not
|
||||
referenced from the anchor `zapret`. Tables are only created for existing list
|
||||
files in the `ipset` directory.

Поддерживаемые версии
|
||||
---------------------
|
||||
|
||||
FreeBSD 11.x+ , OpenBSD 6.x+, частично MacOS Sierra+
|
||||
|
||||
На более старых может собираться, может не собираться, может работать или не работать.
|
||||
На FreeBSD 10 собирается и работает dvtws. С tpws есть проблемы из-за слишком старой версии компилятора clang.
|
||||
Вероятно, будет работать, если обновить компилятор.
|
||||
Возможна прикрутка к последним версиям pfsense без веб интерфейса в ручном режиме через консоль.
|
||||
|
||||
|
||||
Особенности BSD систем
|
||||
----------------------
|
||||
|
||||
В BSD нет nfqueue. Похожий механизм - divert sockets.
|
||||
Из каталога "nfq" под BSD собирается dvtws вместо nfqws.
|
||||
Он разделяет с nfqws большую часть кода и почти совпадает по параметрам командной строки.
|
||||
|
||||
FreeBSD содержит 3 фаервола : IPFilter, ipfw и Packet Filter (PF). OpenBSD содержит только PF.
|
||||
|
||||
Под FreeBSD tpws и dvtws собираются через "make", под OpenBSD - "make bsd", под MacOS - "make mac".
|
||||
FreeBSD make распознает BSDmakefile , OpenBSD и MacOS - нет. Поэтому там используется отдельный target в Makefile.
|
||||
Сборка всех исходников : make -C /opt/zapret
|
||||
|
||||
divert сокет - внутренний тип сокета ядра BSD. Он не привязывается ни к какому сетевому адресу, не участвует
|
||||
в обмене данными через сеть и идентифицируется по номеру порта 1..65535. Аналогия с номером очереди NFQUEUE.
|
||||
На divert сокеты заворачивается трафик посредством правил ipfw или PF.
|
||||
Если в фаерволе есть правило divert, но на divert порту никто не слушает, то пакеты дропаются.
|
||||
Это поведение аналогично правилам NFQUEUE без параметра --queue-bypass.
|
||||
На FreeBSD divert сокеты могут быть только ipv4, хотя на них принимаются и ipv4, и ipv6 фреймы.
|
||||
На OpenBSD divert сокеты создаются отдельно для ipv4 и ipv6 и работают только с одной версией ip каждый.
|
||||
На MacOS похоже, что divert сокеты из ядра вырезаны. См подробнее раздел про MacOS.
|
||||
Отсылка в divert сокет работает аналогично отсылке через raw socket на linux. Передается полностью IP фрейм, начиная
|
||||
с ip загловка . Эти особенности учитываются в dvtws.
|
||||
|
||||
Скрипты ipset/*.sh при наличии ipfw работают с ipfw lookup tables.
|
||||
Это прямой аналог ipset. lookup tables не разделены на v4 и v6. Они могут содержать v4 и v6 адреса и подсети одновременно.
|
||||
Если ipfw отсутствует, то действие зависит от переменной LISTS_RELOAD в config.
|
||||
Если она задана, то выполняется команда из LISTS_RELOAD. В противном случае не делается ничего.
|
||||
Если LISTS_RELOAD=-, то заполнение таблиц отключается даже при наличии ipfw.
|
||||
|
||||
PF может загружать ip таблицы из файла. Чтобы использовать эту возможность следует отключить сжатие gzip для листов
|
||||
через параметр файла config "GZIP_LISTS=0".
|
||||
|
||||
BSD не содержит системного вызова splice. tpws работает через переброску данных в user mode в оба конца.
|
||||
Это медленнее, но не критически.
|
||||
Управление асинхронными сокетами в tpws основано на linux-specific механизме epoll.
|
||||
В BSD для его эмуляции используется epoll-shim - прослойка для эмуляции epoll на базе kqueue.
|
||||
|
||||
mdig и ip2net полностью работоспособны в BSD. В них нет ничего системо-зависимого.
|
||||
|
||||
FreeBSD
|
||||
-------
|
||||
|
||||
divert сокеты требуют специального модуля ядра ipdivert.
|
||||
Поместите следующие строки в /boot/loader.conf (создать, если отсутствует) :
|
||||
-----------
|
||||
ipdivert_load="YES"
|
||||
net.inet.ip.fw.default_to_accept=1
|
||||
-----------
|
||||
В /etc/rc.conf :
|
||||
-----------
|
||||
firewall_enable="YES"
|
||||
firewall_script="/etc/rc.firewall.my"
|
||||
-----------
|
||||
/etc/rc.firewall.my :
|
||||
-----------
|
||||
ipfw -q -f flush
|
||||
-----------
|
||||
В /etc/rc.firewall.my можно дописывать правила ipfw, чтобы они восстанавливались после перезагрузки.
|
||||
Оттуда же можно запускать и демоны zapret, добавив в параметры "--daemon". Например так :
|
||||
-----------
|
||||
pkill ^dvtws$
|
||||
/opt/zapret/nfq/dvtws --port=989 --daemon --dpi-desync=split2
|
||||
-----------
|
||||
Для перезапуска фаервола и демонов достаточно будет сделать : /etc/rc.d/ipfw restart
|
||||
|
||||
|
||||
Краткая инструкция по запуску tpws в прозрачном режиме.
|
||||
Предполагается, что интерфейс LAN называется em1, WAN - em0.
|
||||
|
||||
Для всего трафика :
|
||||
ipfw delete 100
|
||||
ipfw add 100 fwd 127.0.0.1,988 tcp from me to any 80,443 proto ip4 xmit em0 not uid daemon
|
||||
ipfw add 100 fwd ::1,988 tcp from me to any 80,443 proto ip6 xmit em0 not uid daemon
|
||||
ipfw add 100 fwd 127.0.0.1,988 tcp from any to any 80,443 proto ip4 recv em1
|
||||
ipfw add 100 fwd ::1,988 tcp from any to any 80,443 proto ip6 recv em1
|
||||
/opt/zapret/tpws/tpws --port=988 --user=daemon --bind-addr=::1 --bind-addr=127.0.0.1
|
||||
|
||||
Для трафика только на таблицу zapret, за исключением таблицы nozapret :
|
||||
ipfw delete 100
|
||||
ipfw add 100 allow tcp from me to table\(nozapret\) 80,443
|
||||
ipfw add 100 fwd 127.0.0.1,988 tcp from me to table\(zapret\) 80,443 proto ip4 xmit em0 not uid daemon
|
||||
ipfw add 100 fwd ::1,988 tcp from me to table\(zapret\) 80,443 proto ip6 xmit em0 not uid daemon
|
||||
ipfw add 100 allow tcp from any to table\(nozapret\) 80,443 recv em1
|
||||
ipfw add 100 fwd 127.0.0.1,988 tcp from any to any 80,443 proto ip4 recv em1
|
||||
ipfw add 100 fwd ::1,988 tcp from any to any 80,443 proto ip6 recv em1
|
||||
/opt/zapret/tpws/tpws --port=988 --user=daemon --bind-addr=::1 --bind-addr=127.0.0.1
|
||||
|
||||
Таблицы zapret, nozapret, ipban создаются скриптами из ipset по аналогии с Linux.
|
||||
Обновление скриптов можно забить в cron под root :
|
||||
crontab -e
|
||||
Создать строчку "0 12 */2 * * /opt/zapret/ipset/get_config.sh"
|
||||
|
||||
При использовании ipfw tpws не требует повышенных привилегий для реализации прозрачного режима.
|
||||
Однако, без рута невозможен бинд на порты <1024 и смена UID/GID. Без смены UID будет рекурсия,
|
||||
поэтому правила ipfw нужно создавать с учетом UID, под которым работает tpws.
|
||||
Переадресация на порты >=1024 может создать угрозу перехвата трафика непривилегированным
|
||||
процессом, если вдруг tpws не запущен.
|
||||
|
||||
|
||||
Краткая инструкция по запуску dvtws.
|
||||
|
||||
Для всего трафика :
|
||||
ipfw delete 100
|
||||
ipfw add 100 divert 989 tcp from any to any 80,443 out not diverted xmit em0
|
||||
# required for autottl mode only
|
||||
ipfw add 100 divert 989 tcp from any 80,443 to any tcpflags syn,ack in not diverted recv em0
|
||||
/opt/zapret/nfq/dvtws --port=989 --dpi-desync=split2
|
||||
|
||||
Для трафика только на таблицу zapret, за исключением таблицы nozapret :
|
||||
ipfw delete 100
|
||||
ipfw add 100 allow tcp from me to table\(nozapret\) 80,443
|
||||
ipfw add 100 divert 989 tcp from any to table\(zapret\) 80,443 out not diverted not sockarg xmit em0
|
||||
# required for autottl mode only
|
||||
ipfw add 100 divert 989 tcp from table\(zapret\) 80,443 to any tcpflags syn,ack in not diverted not sockarg recv em0
|
||||
/opt/zapret/nfq/dvtws --port=989 --dpi-desync=split2
|
||||
|
||||
|
||||
PF в FreeBSD:
|
||||
Настройка аналогична OpenBSD, но есть важные нюансы.
|
||||
1) В FreeBSD поддержка PF в tpws отключена по умолчанию. Чтобы ее включить, нужно использовать параметр --enable-pf.
|
||||
2) Нельзя сделать ipv6 rdr на ::1. Нужно делать на link-local адрес входящего интерфейса.
|
||||
Смотрите через ifconfig адрес fe80:... и добавляете в правило
|
||||
3) Синтаксис pf.conf немного отличается. Более новая версия PF.
|
||||
4) Лимит на количество элементов таблиц задается так : sysctl net.pf.request_maxcount=2000000
|
||||
5) divert-to сломан. Он работает, но не работает механизм предотвращения зацикливаний.
|
||||
Кто-то уже написал патч, но в 14-RELEASE проблема все еще есть.
|
||||
Следовательно, на данный момент работа dvtws через pf невозможна.
|
||||
|
||||
/etc/pf.conf
|
||||
-----------
|
||||
rdr pass on em1 inet6 proto tcp to port {80,443} -> fe80::31c:29ff:dee2:1c4d port 988
|
||||
rdr pass on em1 inet proto tcp to port {80,443} -> 127.0.0.1 port 988
|
||||
-----------
|
||||
/opt/zapret/tpws/tpws --port=988 --enable-pf --bind-addr=127.0.0.1 --bind-iface6=em1 --bind-linklocal=force
|
||||
|
||||
В PF непонятно как делать rdr-to с той же системы, где работает proxy. Вариант с route-to у меня не заработал.
|
||||
|
||||
|
||||
pfsense
|
||||
-------
|
||||
|
||||
pfsense основано на FreeBSD.
|
||||
pfsense использует фаервол pf, а он имеет проблемы с divert.
|
||||
К счастью, модули ipfw и ipdivert присутствуют в поставке последних версий pfsense.
|
||||
Их можно подгрузить через kldload.
|
||||
В некоторых более старых версиях pfsense требуется изменить порядок фаерволов через sysctl, сделав ipfw первым.
|
||||
В более новых эти параметры sysctl отсутствуют, но система работает как надо и без них.
|
||||
В некоторых случаях фаервол pf может ограничивать возможности dvtws, в частности в области фрагментации ip.
|
||||
Присутствуют по умолчанию правила scrub для реассемблинга фрагментов.
|
||||
Бинарики из binaries/freebsd-x64 собраны под FreeBSD 11. Они должны работать и на последующих версиях FreeBSD,
|
||||
включая pfsense. Можно пользоваться install_bin.sh.
|
||||
|
||||
Пример скрипта автозапуска лежит в init.d/pfsense. Его следует поместить в /usr/local/etc/rc.d и отредактировать
|
||||
на предмет правил ipfw и запуска демонов. Есть встроенный редактор edit как более приемлемая альтернатива vi.
|
||||
Поскольку git отсутствует, копировать файлы удобнее всего через ssh. curl присутствует по умолчанию.
|
||||
Можно скопировать zip с файлами zapret и распаковать в /opt, как это делается на других системах.
|
||||
Тогда dvtws нужно запускать как /opt/zapret/nfq/dvtws. Либо скопировать только dvtws в /usr/local/sbin.
|
||||
Как вам больше нравится.
|
||||
ipset скрипты работают, крон есть. Можно сделать автообновление листов.
|
||||
|
||||
Если вас напрягает бедность имеющегося репозитория, можно включить репозиторий от FreeBSD, который по умолчанию выключен.
|
||||
Поменяйте no на yes в /usr/local/etc/pkg/repos/FreeBSD.conf
|
||||
Можно установить весь привычный soft, включая git, чтобы напрямую скачивать zapret с github.
|
||||
|
||||
/usr/local/etc/rc.d/zapret.sh (chmod 755)
|
||||
-----------
|
||||
#!/bin/sh
|
||||
|
||||
kldload ipfw
|
||||
kldload ipdivert
|
||||
|
||||
# for older pfsense versions. newer do not have these sysctls
|
||||
sysctl net.inet.ip.pfil.outbound=ipfw,pf
|
||||
sysctl net.inet.ip.pfil.inbound=ipfw,pf
|
||||
sysctl net.inet6.ip6.pfil.outbound=ipfw,pf
|
||||
sysctl net.inet6.ip6.pfil.inbound=ipfw,pf
|
||||
|
||||
ipfw delete 100
|
||||
ipfw add 100 divert 989 tcp from any to any 80,443 out not diverted xmit em0
|
||||
pkill ^dvtws$
|
||||
dvtws --daemon --port 989 --dpi-desync=split2
|
||||
|
||||
# required for newer pfsense versions (2.6.0 tested) to return ipfw to functional state
|
||||
pfctl -d ; pfctl -e
|
||||
-----------
|
||||
|
||||
Что касается tpws, то видимо имеется некоторый конфликт двух фаерволов, и правила fwd в ipfw не работают.
|
||||
Работает перенаправление средствами pf как описано в разделе по FreeBSD.
|
||||
В pf можно изменять правила только целыми блоками - якорями (anchors). Нельзя просто так добавить или удалить что-то.
|
||||
Но чтобы какой-то anchor был обработан, на него должна быть ссылка из основного набора правил.
|
||||
Его трогать нельзя, иначе порушится весь фаервол.
|
||||
Поэтому придется править код скриптов pfsense. Поправьте /etc/inc/filter.inc следующим образом :
|
||||
-----------
|
||||
.................
|
||||
/* MOD */
|
||||
$natrules .= "# ZAPRET redirection\n";
|
||||
$natrules .= "rdr-anchor \"zapret\"\n";
|
||||
|
||||
$natrules .= "# TFTP proxy\n";
|
||||
$natrules .= "rdr-anchor \"tftp-proxy/*\"\n";
|
||||
.................
|
||||
-----------
|
||||
|
||||
Напишите файл с содержимым anchor-а (например, /etc/zapret.anchor):
|
||||
-----------
|
||||
rdr pass on em1 inet proto tcp to port {80,443} -> 127.0.0.1 port 988
|
||||
rdr pass on em1 inet6 proto tcp to port {80,443} -> fe80::20c:29ff:5ae3:4821 port 988
|
||||
-----------
|
||||
fe80::20c:29ff:5ae3:4821 замените на ваш link local адрес LAN интерфейса, либо уберите строчку, если ipv6 не нужен.
|
||||
|
||||
Добавьте в автозапуск /usr/local/etc/rc.d/zapret.sh :
|
||||
-----------
|
||||
pfctl -a zapret -f /etc/zapret.anchor
|
||||
pkill ^tpws$
|
||||
tpws --daemon --port=988 --enable-pf --bind-addr=127.0.0.1 --bind-iface6=em1 --bind-linklocal=force --split-http-req=method --split-pos=2
|
||||
-----------
|
||||
|
||||
После перезагрузки проверьте, что правила создались :
|
||||
-----------
|
||||
[root@pfSense /]# pfctl -s nat
|
||||
no nat proto carp all
|
||||
nat-anchor "natearly/*" all
|
||||
nat-anchor "natrules/*" all
|
||||
...................
|
||||
no rdr proto carp all
|
||||
rdr-anchor "zapret" all
|
||||
rdr-anchor "tftp-proxy/*" all
|
||||
rdr-anchor "miniupnpd" all
|
||||
[root@pfSense /]# pfctl -s nat -a zapret
|
||||
rdr pass on em1 inet proto tcp from any to any port = http -> 127.0.0.1 port 988
|
||||
rdr pass on em1 inet proto tcp from any to any port = https -> 127.0.0.1 port 988
|
||||
rdr pass on em1 inet6 proto tcp from any to any port = http -> fe80::20c:29ff:5ae3:4821 port 988
|
||||
rdr pass on em1 inet6 proto tcp from any to any port = https -> fe80::20c:29ff:5ae3:4821 port 988
|
||||
-----------
|
||||
|
||||
Так же есть более элегантный способ запуска tpws через @reboot в cron и правило перенаправления в UI.
|
||||
Это позволит не редактировать код pfsense.
|
||||
|
||||
|
||||
OpenBSD
|
||||
-------
|
||||
|
||||
В tpws бинд по умолчанию только на ipv6. для бинда на ipv4 указать "--bind-addr=0.0.0.0"
|
||||
Используйте --bind-addr=0.0.0.0 --bind-addr=:: для достижения того же результата, как в других ОС по умолчанию.
|
||||
(лучше все же так не делать, а сажать на определенные внутренние адреса или интерфейсы)
|
||||
|
||||
tpws для проходящего трафика :
|
||||
|
||||
/etc/pf.conf
|
||||
------------
|
||||
pass in quick on em1 inet proto tcp to port {80,443} rdr-to 127.0.0.1 port 988
|
||||
pass in quick on em1 inet6 proto tcp to port {80,443} rdr-to ::1 port 988
|
||||
------------
|
||||
pfctl -f /etc/pf.conf
|
||||
tpws --port=988 --user=daemon --bind-addr=::1 --bind-addr=127.0.0.1
|
||||
|
||||
В PF непонятно как делать rdr-to с той же системы, где работает proxy. Вариант с route-to у меня не заработал.
|
||||
Поддержка rdr-to реализована через /dev/pf, поэтому прозрачный режим требует root.
|
||||
|
||||
dvtws для всего трафика :
|
||||
|
||||
/etc/pf.conf
|
||||
------------
|
||||
pass in quick on em0 proto tcp from port {80,443} flags SA/SA divert-packet port 989 no state
|
||||
pass in quick on em0 proto tcp from port {80,443} no state
|
||||
pass out quick on em0 proto tcp to port {80,443} divert-packet port 989 no state
|
||||
------------
|
||||
pfctl -f /etc/pf.conf
|
||||
./dvtws --port=989 --dpi-desync=split2
|
||||
|
||||
dvtws для трафика только на таблицу zapret, за исключением таблицы nozapret :
|
||||
|
||||
/etc/pf.conf
|
||||
------------
|
||||
set limit table-entries 2000000
|
||||
table <zapret> file "/opt/zapret/ipset/zapret-ip.txt"
|
||||
table <zapret-user> file "/opt/zapret/ipset/zapret-ip-user.txt"
|
||||
table <nozapret> file "/opt/zapret/ipset/zapret-ip-exclude.txt"
|
||||
pass out quick on em0 inet proto tcp to <nozapret> port {80,443}
|
||||
pass in quick on em0 inet proto tcp from <zapret> port {80,443} flags SA/SA divert-packet port 989 no state
|
||||
pass in quick on em0 inet proto tcp from <zapret> port {80,443} no state
|
||||
pass out quick on em0 inet proto tcp to <zapret> port {80,443} divert-packet port 989 no state
|
||||
pass in quick on em0 inet proto tcp from <zapret-user> port {80,443} flags SA/SA divert-packet port 989 no state
|
||||
pass in quick on em0 inet proto tcp from <zapret-user> port {80,443} no state
|
||||
pass out quick on em0 inet proto tcp to <zapret-user> port {80,443} divert-packet port 989 no state

pfctl -f /etc/pf.conf
|
||||
./dvtws --port=989 --dpi-desync=split2
|
||||
|
||||
divert-packet автоматически вносит обратное правило для перенаправления.
|
||||
Трюк с no state и in правилом позволяет обойти эту проблему, чтобы напрасно не гнать массивный трафик через dvtws.
|
||||
|
||||
В OpenBSD dvtws все фейки отсылает через divert socket, поскольку эта возможность через raw sockets заблокирована.
|
||||
Видимо pf автоматически предотвращает повторный заворот diverted фреймов, поэтому проблемы зацикливания нет.
|
||||
|
||||
OpenBSD принудительно пересчитывает tcp checksum после divert, поэтому скорее всего
|
||||
dpi-desync-fooling=badsum у вас не заработает. При использовании этого параметра
|
||||
dvtws предупредит о возможной проблеме.
|
||||
|
||||
Скрипты из ipset не перезагружают таблицы в PF по умолчанию.
|
||||
Чтобы они это делали, добавьте параметр в /opt/zapret/config :
|
||||
LISTS_RELOAD="pfctl -f /etc/pf.conf"
|
||||
Более новые версии pfctl понимают команду перезагрузить только таблицы : pfctl -Tl -f /etc/pf.conf
|
||||
Но это не относится к OpenBSD 6.8. В новых FreeBSD есть.
|
||||
Не забудьте выключить сжатие gzip :
|
||||
GZIP_LISTS=0
|
||||
Если в вашей конфигурации какого-то файла листа нет, то его необходимо исключить из правил PF.
|
||||
Если вдруг листа нет, и он задан в pf.conf, будет ошибка перезагрузки фаервола.
|
||||
После настройки обновление листов можно поместить в cron :
|
||||
crontab -e
|
||||
дописать строчку : 0 12 */2 * * /opt/zapret/ipset/get_config.sh
|
||||

||||
MacOS
|
||||
-----
|
||||
|
||||
Иначально ядро этой ОС "darwin" основывалось на BSD, потому в ней много похожего на другие версии BSD.
|
||||
Однако, как и в других массовых коммерческих проектах, приоритеты смещаются в сторону от оригинала.
|
||||
Яблочники что хотят, то и творят.
|
||||
Раньше был ipfw, потом его убрали, заменили на PF.
|
||||
Есть сомнения, что divert сокеты в ядре остались. Попытка создать divert socket не выдает ошибок,
|
||||
но полученный сокет ведет себя точно так же, как raw, со всеми его унаследованными косяками + еще яблочно специфическими.
|
||||
В PF divert-packet не работает. Простой grep бинарика pfctl показывает, что там нет слова "divert",
|
||||
а в других версиях BSD оно есть. dvtws собирается, но совершенно бесполезен.
|
||||
|
||||
tpws удалось адаптировать, он работоспособен. Получение адреса назначения для прозрачного прокси в PF (DIOCNATLOOK)
|
||||
убрали из заголовков в новых SDK, сделав фактически недокументированным.
|
||||
В tpws перенесены некоторые определения из более старых версий яблочных SDK. С ними удалось завести прозрачный режим.
|
||||
Однако, что будет в следующих версиях угадать сложно. Гарантий нет.
|
||||
Еще одной особенностью PF в MacOS является проверка на рута в момент обращения к /dev/pf, чего нет в остальных BSD.
|
||||
tpws по умолчанию сбрасывает рутовые привилегии. Необходимо явно указать параметр --user=root.
|
||||
В остальном PF себя ведет похоже на FreeBSD. Синтаксис pf.conf тот же.
|
||||
|
||||
На MacOS работает редирект как с проходящего трафика, так и с локальной системы через route-to.
|
||||
Поскольку tpws вынужден работать под root, для исключения рекурсии приходится пускать исходящий от root трафик напрямую.
|
||||
Отсюда имеем недостаток : обход DPI для рута работать не будет.
|
||||
|
||||
Если вы пользуетесь MaсOS в качестве ipv6 роутера, то нужно будет решить вопрос с регулярно изменяемым link-local адресом.
|
||||
С некоторых версий MacOS использует по умолчанию постоянные "secured" ipv6 адреса вместо генерируемых на базе MAC адреса.
|
||||
Все замечательно, но есть одна проблема. Постоянными остаются только global scope адреса.
|
||||
Link locals периодически меняются. Смена завязана на системное время. Перезагрузки адрес не меняют,
|
||||
Но если перевести время на день вперед и перезагрузиться - link local станет другим. (по крайней мере в vmware это так)
|
||||
Информации по вопросу крайне мало, но тянет на баг. Не должен меняться link local. Скрывать link local не имеет смысла,
|
||||
а динамический link local нельзя использовать в качестве адреса шлюза.
|
||||
Проще всего отказаться от "secured" адресов.
|
||||
Поместите строчку "net.inet6.send.opmode=0" в /etc/sysctl.conf. Затем перезагрузите систему.
|
||||
Все равно для исходящих соединений будут использоваться temporary адреса, как и в других системах.
|
||||
Или вам идея не по вкусу, можно прописать дополнительный статический ipv6 из диапазона fc00::/7 -
|
||||
выберите любой с длиной префикса 128. Это можно сделать в системных настройках, создав дополнительный адаптер на базе
|
||||
того же сетевого интерфейса, отключить в нем ipv4 и вписать статический ipv6. Он добавится к автоматически настраеваемым.
|
||||
|
||||
Настройка tpws на macos в прозрачном режиме только для исходящих запросов :
|
||||
|
||||
/etc/pf.conf
|
||||
------------
|
||||
rdr pass on lo0 inet proto tcp from !127.0.0.0/8 to any port {80,443} -> 127.0.0.1 port 988
|
||||
rdr pass on lo0 inet6 proto tcp from !::1 to any port {80,443} -> fe80::1 port 988
|
||||
pass out route-to (lo0 127.0.0.1) inet proto tcp from any to any port {80,443} user { >root }
|
||||
pass out route-to (lo0 fe80::1) inet6 proto tcp from any to any port {80,443} user { >root }
|
||||
------------
|
||||
pfctl -ef /etc/pf.conf
|
||||
/opt/zapret/tpws/tpws --user=root --port=988 --bind-addr=127.0.0.1 --bind-iface6=lo0 --bind-linklocal=force
|
||||
|
||||
|
||||
Настройка tpws на macos роутере в прозрачном режиме, где en1 - LAN.
|
||||
|
||||
ifconfig en1 | grep fe80
|
||||
inet6 fe80::bbbb:bbbb:bbbb:bbbb%en1 prefixlen 64 scopeid 0x8
|
||||
/etc/pf.conf
|
||||
------------
|
||||
rdr pass on en1 inet proto tcp from any to any port {80,443} -> 127.0.0.1 port 988
|
||||
rdr pass on en1 inet6 proto tcp from any to any port {80,443} -> fe80::bbbb:bbbb:bbbb:bbbb port 988
|
||||
rdr pass on lo0 inet proto tcp from !127.0.0.0/8 to any port {80,443} -> 127.0.0.1 port 988
|
||||
rdr pass on lo0 inet6 proto tcp from !::1 to any port {80,443} -> fe80::1 port 988
|
||||
pass out route-to (lo0 127.0.0.1) inet proto tcp from any to any port {80,443} user { >root }
|
||||
pass out route-to (lo0 fe80::1) inet6 proto tcp from any to any port {80,443} user { >root }
|
||||
------------
|
||||
pfctl -ef /etc/pf.conf
|
||||
/opt/zapret/tpws/tpws --user=root --port=988 --bind-addr=127.0.0.1 --bind-iface6=lo0 --bind-linklocal=force --bind-iface6=en1 --bind-linklocal=force
|
||||
|
||||
|
||||
Сборка : make -C /opt/zapret mac
|
||||
|
||||
Скрипты получения листов ipset/*.sh работают.
|
||||
Если будете пользоваться ipset/get_combined.sh, нужно установить gnu grep через brew.
|
||||
Имеющийся очень старый и безумно медленный с оцией -f.
|
||||
|
||||
|
||||
MacOS простая установка
|
||||
-----------------------
|
||||
|
||||
В MacOS поддерживается install_easy.sh
|
||||
|
||||
В комплекте идут бинарики, собраные под 64-bit с опцией -mmacosx-version-min=10.8.
|
||||
Они должны работать на всех поддерживаемых версиях macos.
|
||||
Если вдруг не работают - можно собрать свои. Developer tools ставятся автоматом при запуске make.
|
||||
|
||||
!! Internet sharing средствами системы НЕ ПОДДЕРЖИВАЕТСЯ !!
|
||||
Поддерживается только роутер, настроенный своими силами через PF.
|
||||
Если вы вдруг включили шаринг, а потом выключили, то доступ к сайтам может пропасть совсем.
|
||||
Лечение : pfctl -f /etc/pf.conf
|
||||
Если вам нужен шаринг интернета, лучше отказаться от прозрачного режима и использовать socks.
|
||||
|
||||
Для автостарта используется launchd (/Library/LaunchDaemons/zapret.plist)
|
||||
Управляющий скрипт : /opt/zapret/init.d/macos/zapret
|
||||
Следующие команды работают с tpws и фаерволом одновременно (если INIT_APPLY_FW=1 в config)
|
||||
/opt/zapret/init.d/macos/zapret start
|
||||
/opt/zapret/init.d/macos/zapret stop
|
||||
/opt/zapret/init.d/macos/zapret restart
|
||||
Работа только с tpws :
|
||||
/opt/zapret/init.d/macos/zapret start-daemons
|
||||
/opt/zapret/init.d/macos/zapret stop-daemons
|
||||
/opt/zapret/init.d/macos/zapret restart-daemons
|
||||
Работа только с PF :
|
||||
/opt/zapret/init.d/macos/zapret start-fw
|
||||
/opt/zapret/init.d/macos/zapret stop-fw
|
||||
/opt/zapret/init.d/macos/zapret restart-fw
|
||||
Перезагрузка всех IP таблиц из файлов :
|
||||
/opt/zapret/init.d/macos/zapret reload-fw-tables
|
||||
|
||||
Инсталятор настраивает LISTS_RELOAD в config, так что скрипты ipset/*.sh автоматически перезагружают IP таблицы в PF.
|
||||
Автоматически создается cron job на ipset/get_config.sh, по аналогии с openwrt.
|
||||
|
||||
При start-fw скрипт автоматически модицифирует /etc/pf.conf, вставляя туда anchors "zapret".
|
||||
Модификация расчитана на pf.conf, в котором сохранены дефолтные anchors от apple.
|
||||
Если у вас измененный pf.conf и модификация не удалась, об этом будет предупреждение. Не игнорируйте его.
|
||||
В этом случае вам нужно вставить в свой pf.conf (в соответствии с порядком типов правил) :
|
||||
rdr-anchor "zapret"
|
||||
anchor "zapret"
|
||||
При деинсталяции через uninstall_easy.sh модификации pf.conf убираются.
|
||||
|
||||
start-fw создает 3 файла anchors в /etc/pf.anchors : zapret,zapret-v4,zapret-v6.
|
||||
Последние 2 подключаются из anchor "zapret".
|
||||
Таблицы nozapret,nozapret6 принадлежат anchor "zapret".
|
||||
Таблицы zapret,zapret-user - в anchor "zapret-v4".
|
||||
Таблицы zapret6,zapret6-user - в anchor "zapret-v6".
|
||||
Если какая-то версия протокола отключена - соответствующий anchor пустой и не упоминается в anchor "zapret".
|
||||
Таблицы и правила создаются только на те листы, которые фактически есть в директории ipset.
|
||||
|
||||
|
||||
MacOS вариант custom
|
||||
--------------------
|
||||
|
||||
Так же как и в других системах, поддерживаемых в простом инсталяторе, можно создавать свои custom скрипты.
|
||||
Расположение : /opt/zapret/init.d/macos/custom
|
||||
|
||||
zapret_custom_daemons() получает в $1 "0" или "1". "0" - stop, "1" - start
|
||||
custom firewall отличается от linux варианта.
|
||||
Вместо заполнения iptables вам нужно сгенерировать правила для zapret-v4 и zapret-v6 anchors и выдать их в stdout.
|
||||
Это делается в функциях zapret_custom_firewall_v4() и zapret_custom_firewall_v6().
|
||||
Определения таблиц заполняются основным скриптом - вам это делать не нужно.
|
||||
Можно ссылаться на таблицы zapret и zapret-user в v4, zapret6 и zapret6-user.
|
||||

||||

How to compile native programs for use in openwrt
|
||||
-------------------------------------------------
|
||||
|
||||
1) <fetch correct version of openwrt>
|
||||
|
||||
cd ~
|
||||
|
||||
<chaos calmer>
|
||||
git clone git://git.openwrt.org/15.05/openwrt.git
|
||||
<barrier breaker>
|
||||
git clone git://git.openwrt.org/14.07/openwrt.git
|
||||
<trunk>
|
||||
git clone git://git.openwrt.org/openwrt.git
|
||||
|
||||
cd openwrt
|
||||
|
||||
2) ./scripts/feeds update -a
|
||||
./scripts/feeds install -a
|
||||
|
||||
3) #add zapret packages to build root
|
||||
#copy package descriptions
|
||||
copy compile/openwrt/* to ~/openwrt
|
||||
#copy source code of tpws
|
||||
copy tpws to ~/openwrt/package/zapret/tpws
|
||||
#copy source code of nfq
|
||||
copy nfq to ~/openwrt/package/zapret/nfq
|
||||
#copy source code of ip2net
|
||||
copy ip2net to ~/openwrt/package/zapret/ip2net
|
||||
|
||||
4) make menuconfig
|
||||
#select your target architecture
|
||||
#select packages Network/Zapret/* as "M"
|
||||
|
||||
5) make toolchain/compile
|
||||
|
||||
6) make package/tpws/compile
|
||||
make package/nfqws/compile
|
||||
make package/ip2net/compile
|
||||
make package/mdig/compile
|
||||
|
||||
7) find bin -name tpws*.ipk
|
||||
#take your tpws*.ipk , nfqws*.ipk , ip2net*.ipk, mdig*.ipk from there

Пример ручной установки на debian-подобную систему
|
||||
--------------------------------------------------
|
||||
|
||||
На debian основано большое количество дистрибутивов linux, включая ubuntu.
|
||||
Здесь рассматриваются прежде всего Debian 8+ и Ubuntu 16+.
|
||||
Но с большой вероятностью может сработать и на производных от них.
|
||||
Главное условие - наличие systemd, apt и нескольких стандартных пакетов в репозитории.
|
||||
|
||||
Установить пакеты :
|
||||
apt-get update
|
||||
apt-get install ipset curl dnsutils git
|
||||
|
||||
Если хотите использовать nftables, то нужен пакет nftables, а ipset не обязателен.
|
||||
|
||||
Скопировать директорию zapret в /opt или скачать через git :
|
||||
cd /opt
|
||||
git clone --depth 1 https://github.com/bol-van/zapret
|
||||
|
||||
Запустить автоинсталятор бинариков. Он сам определит рабочую архитектуру и настроит все бинарики.
|
||||
/opt/zapret/install_bin.sh
|
||||
АЛЬТЕРНАТИВА : make -C /opt/zapret. Получите динамические бинарики под вашу ось.
|
||||
Для сборки требуются dev пакеты : zlib1g-dev libcap-dev libnetfilter-queue-dev
|
||||
|
||||
Создать конфиг по умолчанию :
|
||||
cp /opt/zapret/config.default /opt/zapret/config
|
||||
|
||||
Настроить параметры согласно разделу "Выбор параметров".
|
||||
|
||||
Создать user листы по умолчанию :
|
||||
cp /opt/zapret/ipset/zapret-hosts-user-exclude.txt.default /opt/zapret/ipset/zapret-hosts-user-exclude.txt
|
||||
echo nonexistent.domain >/opt/zapret/ipset/zapret-hosts-user.txt
|
||||
touch /opt/zapret/ipset/zapret-hosts-user-ipban.txt
|
||||
|
||||
Создать ссылку на service unit в systemd :
|
||||
ln -fs /opt/zapret/init.d/systemd/zapret.service /lib/systemd/system
|
||||
|
||||
Удалить старые листы, если они были созданы ранее :
|
||||
/opt/zapret/ipset/clear_lists.sh
|
||||
По желанию прописать в /opt/zapret/ipset/zapret-hosts-user.txt свои домены.
|
||||
Выполнить скрипт обновления листа :
|
||||
/opt/zapret/ipset/get_config.sh
|
||||
Настроить таймер systemd для обновления листа :
|
||||
ln -fs /opt/zapret/init.d/systemd/zapret-list-update.service /lib/systemd/system
|
||||
ln -fs /opt/zapret/init.d/systemd/zapret-list-update.timer /lib/systemd/system
|
||||
|
||||
Принять изменения в systemd :
|
||||
systemctl daemon-reload
|
||||
|
||||
Включить автозапуск службы :
|
||||
systemctl enable zapret
|
||||
|
||||
Включить таймер обновления листа :
|
||||
systemctl enable zapret-list-update.timer
|
||||
|
||||
Запустить службу :
|
||||
systemctl start zapret
|
||||
|
||||
Шпаргалка по управлению службой и таймером :
|
||||
|
||||
enable auto start : systemctl enable zapret
|
||||
disable auto start : systemctl disable zapret
|
||||
start : systemctl start zapret
|
||||
stop : systemctl stop zapret
|
||||
status, output messages : systemctl status zapret
|
||||
timer info : systemctl list-timer
|
||||
delete service : systemctl disable zapret ; rm /lib/systemd/system/zapret.service
|
||||
delete timer : systemctl disable zapret-list-update.timer ; rm /lib/systemd/system/zapret-list-update.*
|
||||
|
||||
Centos 7+, Fedora
|
||||
-----------------
|
||||
|
||||
Centos с 7 версии и более-менее новые федоры построены на systemd.
|
||||
В качестве пакетного менеджера используется yum.
|
||||
|
||||
Установить пакеты :
|
||||
yum install -y curl ipset dnsutils git
|
||||
|
||||
Далее все аналогично debian.
|
||||
|
||||
OpenSUSE
|
||||
--------
|
||||
|
||||
Новые OpenSUSE основаны на systemd и менеджере пакетов zypper.
|
||||
|
||||
Установить пакеты :
|
||||
zypper --non-interactive install curl ipset
|
||||
|
||||
Далее все аналогично debian, кроме расположения systemd.
|
||||
В opensuse он находится не в /lib/systemd, а в /usr/lib/systemd.
|
||||
Правильные команды будут :
|
||||
|
||||
ln -fs /opt/zapret/init.d/systemd/zapret.service /usr/lib/systemd/system
|
||||
ln -fs /opt/zapret/init.d/systemd/zapret-list-update.service /usr/lib/systemd/system
|
||||
ln -fs /opt/zapret/init.d/systemd/zapret-list-update.timer /usr/lib/systemd/system
|
||||
|
||||
Arch linux
|
||||
----------
|
||||
|
||||
Построен на базе systemd.
|
||||
|
||||
Установить пакеты :
|
||||
pacman -Syy
|
||||
pacman --noconfirm -S ipset curl
|
||||
|
||||
Далее все аналогично debian.
|
||||
|
||||
Gentoo
|
||||
------
|
||||
|
||||
Эта система использует OpenRC - улучшенную версию sysvinit.
|
||||
Установка пакетов производится командой : emerge <package_name>
|
||||
Пакеты собираются из исходников.
|
||||
|
||||
Требуются все те же ipset, curl, git для скачивания с github.
|
||||
git и curl по умолчанию могут присутствовать, ipset отсутствует.
|
||||
|
||||
emerge ipset
|
||||
|
||||
Настроить параметры согласно разделу "Выбор параметров".
|
||||
|
||||
Запустить автоинсталятор бинариков. Он сам определит рабочую архитектуру и настроит все бинарики.
|
||||
/opt/zapret/install_bin.sh
|
||||
АЛЬТЕРНАТИВА : make -C /opt/zapret. Получите динамические бинарики под вашу ось.
|
||||
|
||||
Удалить старые листы, если они были созданы ранее :
|
||||
/opt/zapret/ipset/clear_lists.sh
|
||||
По желанию прописать в /opt/zapret/ipset/zapret-hosts-user.txt свои домены.
|
||||
Выполнить скрипт обновления листа :
|
||||
/opt/zapret/ipset/get_config.sh
|
||||
Зашедулить обновление листа :
|
||||
crontab -e
|
||||
Создать строчку "0 12 */2 * * /opt/zapret/ipset/get_config.sh"
|
||||
|
||||
Подключить init скрипт :
|
||||
|
||||
ln -fs /opt/zapret/init.d/openrc/zapret /etc/init.d
|
||||
rc-update add zapret
|
||||
|
||||
Запустить службу :
|
||||
|
||||
rc-service zapret start
|
||||
|
||||
Шпаргалка по управлению службой :
|
||||
|
||||
enable auto start : rc-update add zapret
|
||||
disable auto start : rc-update del zapret
|
||||
start : rc-service zapret start
|
||||
stop : rc-service zapret stop
|
||||
|
||||
|
||||
|
||||
Ручная установка на openwrt/LEDE 15.xx-21.xx
|
||||
--------------------------------------------
|
||||
|
||||
!!! Данная инструкция написана для систем, основанных на iptables+firewall3
|
||||
!!! В новых версиях openwrt переходит на nftables+firewall4, инструкция неприменима. Пользуйтесь install_easy.sh
|
||||
|
||||
Установить дополнительные пакеты :
|
||||
opkg update
|
||||
opkg install iptables-mod-extra iptables-mod-nfqueue iptables-mod-filter iptables-mod-ipopt iptables-mod-conntrack-extra ipset curl
|
||||
(ipv6) opkg install ip6tables-mod-nat
|
||||
(опционально) opkg install gzip
|
||||
(опционально) opkg install coreutils-sort
|
||||
|
||||
ЭКОНОМИЯ МЕСТА :
|
||||
|
||||
gzip от busybox в разы медленней полноценного варианта. gzip используется скриптами получения листов.
|
||||
sort от busybox медленней полноценного варианта и жрет намного больше памяти. sort используется скриптами получения листов.
|
||||
iptables-mod-nfqueue можно выкинуть, если не будем пользоваться nfqws
|
||||
curl можно выкинуть, если для получения ip листа будет использоваться только get_user.sh
|
||||
|
||||
Самая главная трудность - скомпилировать программы на C. Это можно сделать на linux x64 при помощи SDK, который
|
||||
можно скачать с официального сайта openwrt или LEDE. Но процесс кросс компиляции - это всегда сложности.
|
||||
Недостаточно запустить make как на традиционной linux системе.
|
||||
Поэтому в binaries имеются готовые статические бинарики для всех самых распространенных архитектур.
|
||||
Статическая сборка означает, что бинарик не зависит от типа libc (glibc, uclibc или musl) и наличия установленных so.
|
||||
Его можно использовать сразу. Лишь бы подходил тип CPU. У ARM и MIPS есть несколько версий.
|
||||
Скорее всего найдется рабочий вариант. Если нет - вам придется собирать самостоятельно.
|
||||
Для всех поддерживаемых архитектур бинарики запакованы upx. На текущий момент все, кроме mips64.
|
||||
|
||||
Скопировать директорию "zapret" в /opt на роутер.
|
||||
|
||||
Если места достаточно, самый простой способ :
|
||||
opkg update
|
||||
opkg install git-http
|
||||
mkdir /opt
|
||||
cd /opt
|
||||
git clone --depth 1 https://github.com/bol-van/zapret
|
||||
|
||||
Если места немного :
|
||||
opkg update
|
||||
opkg install openssh-sftp-server unzip
|
||||
ifconfig br-lan
|
||||
Скачать на комп с github zip архив кнопкой "Clone or download"->Download ZIP
|
||||
Скопировать средствами sftp zip архив на роутер в /tmp.
|
||||
mkdir /opt
|
||||
cd /opt
|
||||
unzip /tmp/zapret-master.zip
|
||||
mv zapret-master zapret
|
||||
rm /tmp/zapret-master.zip
|
||||
|
||||
Если места совсем мало :
|
||||
На linux системе скачать и распаковать zapret. Оставить необходимый минимум файлов.
|
||||
Запаковать в архив zapret.tar.gz.
|
||||
nc -l -p 1111 <zapret.tar.gz
|
||||
На роутере
|
||||
cd /tmp
|
||||
nc <linux_system_ip> 1111 >zapret.tar.gz
|
||||
|
||||
Не стоит работать с распакованной версией zapret на windows. Потеряются ссылки и chmod.
|
||||
|
||||
Запустить автоинсталятор бинариков. Он сам определит рабочую архитектуру и настроит все бинарики.
|
||||
/opt/zapret/install_bin.sh
|
||||
|
||||
Создать ссылку на скрипт запуска :
|
||||
ln -fs /opt/zapret/init.d/openwrt/zapret /etc/init.d
|
||||
Создать ссылку на скрипт события поднятия интерфейса :
|
||||
ln -fs /opt/zapret/init.d/openwrt/90-zapret /etc/hotplug.d/iface
|
||||
|
||||
Создать конфиг по умолчанию :
|
||||
cp /opt/zapret/config.default /opt/zapret/config
|
||||
|
||||
Настроить параметры согласно разделу "Выбор параметров".
|
||||
|
||||
Создать user листы по умолчанию :
|
||||
cp /opt/zapret/ipset/zapret-hosts-user-exclude.txt.default /opt/zapret/ipset/zapret-hosts-user-exclude.txt
|
||||
echo nonexistent.domain >/opt/zapret/ipset/zapret-hosts-user.txt
|
||||
touch /opt/zapret/ipset/zapret-hosts-user-ipban.txt
|
||||
|
||||
Удалить старые листы, если они были созданы ранее :
|
||||
/opt/zapret/ipset/clear_lists.sh
|
||||
По желанию прописать в /opt/zapret/ipset/zapret-hosts-user.txt свои домены.
|
||||
Выполнить скрипт обновления листа :
|
||||
/opt/zapret/ipset/get_config.sh
|
||||
Зашедулить обновление листа :
|
||||
crontab -e
|
||||
Создать строчку "0 12 */2 * * /opt/zapret/ipset/get_config.sh"
|
||||
|
||||
Включить автозапуск службы и запустить ее :
|
||||
/etc/init.d/zapret enable
|
||||
/etc/init.d/zapret start
|
||||
ПРИМЕЧАНИЕ : на этапе старта системы интерфейсы еще не подняты. в некоторых случаях невозможно правильно
|
||||
сформировать параметры запуска демонов, не зная имя физического интерфейса LAN.
|
||||
Cкрипт из /etc/hotplug.d/iface перезапустит демоны по событию поднятия LAN.
|
||||
|
||||
Создать ссылку на firewall include :
|
||||
ln -fs /opt/zapret/init.d/openwrt/firewall.zapret /etc/firewall.zapret
|
||||
Проверить была ли создана ранее запись о firewall include :
|
||||
uci show firewall | grep firewall.zapret
|
||||
Если firewall.zapret нет, значит добавить :
|
||||
uci add firewall include
|
||||
uci set firewall.@include[-1].path="/etc/firewall.zapret"
|
||||
uci set firewall.@include[-1].reload="1"
|
||||
uci commit firewall
|
||||
Проверить не включен ли flow offload :
|
||||
uci show firewall.@defaults[0]
|
||||
Если flow_offloading=1 или flow_offloading_hw=1 ,
|
||||
uci set firewall.@defaults[0].flow_offloading=0
|
||||
uci set firewall.@defaults[0].flow_offloading_hw=0
|
||||
uci commit firewall
|
||||
Перезапустить фаервол :
|
||||
fw3 restart
|
||||
|
||||
Посмотреть через iptables -nL, ip6tables -nL или через luci вкладку "firewall" появились ли нужные правила.
|
||||
|
||||
ЭКОНОМИЯ МЕСТА : если его мало, то можно оставить в директории zapret лишь подкаталоги
|
||||
ipset, common, файл config, init.d/openwrt.
|
||||
Далее нужно создать подкаталоги с реально используемыми бинариками (ip2net, mdig, tpws, nfq)
|
||||
и скопировать туда из binaries рабочие executables.
|
||||
|
||||
ЕСЛИ ВСЕ ПЛОХО С МЕСТОМ : откажитесь от работы со списком РКН. используйте только get_user.sh
|
||||
|
||||
ЕСЛИ СОВСЕМ ВСЕ УЖАСНО С МЕСТОМ : берете tpws и делаете все своими руками. поднятие iptables, автостарт бинарика.
|
||||
С некоторых версий скрипты запуска zapret без ipset не работают (он требуется для ip exclude)
|
||||
|
||||
СОВЕТ : Покупайте только роутеры с USB. В USB можно воткнуть флэшку и вынести на нее корневую файловую систему
|
||||
или использовать ее в качестве оверлея. Не надо мучать себя, запихивая незапихиваемое в 8 мб встроенной флэшки.
|
||||
Для комфортной работы с zapret нужен роутер с 16 Mb встроенной памяти или USB разъемом и 128+ Mb RAM.
|
||||
На 64 Mb без swap будут проблемы с листами РКН. Если у вас только 64 Mb, и вы хотите листы РКН, подключите swap.
|
||||
32 Mb для современных версий openwrt - конфигурация на грани живучести. Возможны хаотические падения процессов в oom.
|
||||
Работа с листами РКН невозможна в принципе.

|

nftables - это технология, пришедшая на замену iptables.
|
||||
В ней собрали все, что относилось к различным iptables. А их немало. iptables, ip6tables, ebtables, arptables, ipset.
|
||||
Весь код из разрозненных, но похожих компонент, собрали в одно целое с единым синтаксисом.
|
||||
Добавили различные конструкции языка, позволяющие писать правила более лаконично, не повторяя одни и те же команды с небольшими различиями.
|
||||
На nftables можно сделать почти все, что можно было сделать на iptables. Есть то, что можно сделать на nftables, но нельзя на iptables.
|
||||
Есть и наоборот.
|
||||
|
||||
К сожалению, не обошлось и без боли.
|
||||
|
||||
Главная боль N1. Очень серьезная, актуальная для openwrt, и решения не видно.
|
||||
|
||||
ipset-ы позволяли загонять пересекающиеся интервалы ip адресов или подсетей.
|
||||
nftables sets это не позволяют. Любое пересечение вызывает ошибку.
|
||||
Есть auto-merge, но это работает только в user mode в процессе nft, при условии, что весь блок адресов загоняется одной командой
|
||||
и нет пересечений с уже имеющимся контентом в set.
|
||||
Это не было бы критической проблемой, поскольку скрипты zapret и так загоняют ipset целиком.
|
||||
Проблема в катастрофическом расходе памяти при операции загона больших интервальных листов, то есть с подсетями и диапазонами.
|
||||
Чтобы загнать 100000 ipv4 записей, едва хватает 300 Mb памяти устройства.
|
||||
При успехе операции в ядре список столько не занимает, но суть дела это не меняет.
|
||||
Для традиционных linux систем это не проблема, но почти все роутеры загнутся.
|
||||
Приемлемого решения не просматривается.
|
||||
Сделать записи непересекающимися в листах - задача непростая. Потребуется переписать алгоритм auto-merge из nft,
|
||||
но с пониженным расходом памяти.
|
||||
Загонять записи по одному отдельными вызовами nft, игнорируя ошибки, займет вечность.
|
||||
Загонять блоком отдельных команд, игнорируя ошибки, - nft такого не умеет. Похоже, при любой ошибке происходит откат всего скрипта.
|
||||
К тому же при таком подходе будут неточности в итоговом результате.
|
||||
Swap позволяет немного сгладить проблему, но лишь незначительно.
|
||||
Скажем, если вдруг list загоняется без ошибок с 300 Mb памяти и с падением на 256 Mb, то swap спасает.
|
||||
Если памяти становится 200 Mb, то swap уже не спасет. Все равно вызывается OOM killer, заодно убивая и другие процессы, кроме nft,
|
||||
а это уже совсем плохо. Может быть убито что-то важное.
|
||||
|
||||
Боль N2, не смертельная, но тоже не айс.
|
||||
|
||||
Какие-то нерациональные алгоритмы разбора таблиц в nft.
|
||||
Например, есть 1 большой set на 100000 элементов и 1 маленький на 2 элемента.
|
||||
Чтобы просто пролистать мелкий set или добавить туда еще что-то nft будет мусолить несколько секунд.
|
||||
Что он делает за это время ? Тащит из ядра огромный блоб, в котором все в куче, и разбирает его, чтобы выделить искомую мелочь ?
|
||||
В какой-то мере удается это сгладить, обьединяя несколько команд в единый скрипт.
|
||||
|
||||
Боль N3
|
||||
|
||||
Система nftables построена на виртуальной машине. Правила, которые вы пишите, переводятся в псевдокод VM.
|
||||
Чтобы потом их показать , nft декомпилирует код и переводит в читаемый язык.
|
||||
Это довольно сложно, и регулярно случаются баги, связанные с неверным отображением.
|
||||
|
||||
Кроме этого, часто встречаются и баги парсера.
|
||||
Например, все версии nft вплоть до 1.0.1 имеют баг, который не разрешает названия интерфейсов в кавычках в

определении flowtable. Без кавычек нельзя вставить интерфейсы , имя которых начинается с цифры.
|
||||
OpenWRT решает эту проблему отдельным патчем в snapshot версии, но на традиционных системах и в openwrt 21.x- его нет.
|
||||
Почему бы не наплевать на интерфейсы, начинающиеся с цифры ? Потому что для openwrt 6to4-6to4, 6in4-he-net - обычное явление.
|
||||
На текущий момент этой проблемы в openwrt уже нет, если использовать актуальную версию.
|
||||
|
||||
Но тем не менее, хоть nft и давно перешел отметку 1.0, всякая мелочь, особенно на не совсем стандартных правилах,
|
||||
регулярно всплывает. Потому чем новее у вас будет версия nft, тем больше там выловлено проблем.
|
||||
Здесь обновления важны, чтобы потом не мучаться из-за давно исправленного велосипеда.
|

Боль N4
|
||||
|
||||
Невозможно , не копаясь в других таблицах и хуках, ничего не зная об их содержании, предотвратить DROP или REJECT.
|
||||
Нельзя написать такое правило, которое что-то важное ACCEPTнет, игнорируя остальные хуки во всех таблицах.
|
||||
Если у вас есть какой-то фаервол, и он что-то дропает, то как от этого отказаться, если надо временно что-то принять ?
|
||||
Это особенность netfilter, он так работает, но в iptables есть лишь стандартные таблицы с их хуками, куда можно
|
||||
вставить ACCEPT. Здесь хуков может быть сколько угодно в каких угодно таблицах.
|
||||
Эта проблема частично ломает кайф от независимого управления таблицами.
|
||||
|
||||
|
||||
Плюс N1, главный
|
||||
|
||||
iptables хороши, когда ими пользуется кто-то один. Иначе это проходной двор.
|
||||
Когда есть система управления фаерволом, то приходится как-то к ней прикручиваться, чтобы не нарушить ее работу
|
||||
и управлять правилами синхронно. Нужно уметь внести и удалить отдельные правила когда это нужно, не трогая все остальное.
|
||||
Некоторые системы управления фаерволом вообще не предполагают, чтобы кто-то еще лез в iptables, и это очень сильно портит жизнь.
|
||||
У iptables есть предопределенный набор хуков netfilter с фиксированным приоритетом.
|
||||
В nftables хуков можно создать неограниченное количество с выбранным приоритетом, управляя ими независимо в отдельных таблицах.
|
||||
Система управления фаерволом может работать в одной таблице (fw4 в случае openwrt) и не трогать все остальное.
|
||||
zapret может работать в другой таблице и не трогать систему управления фаерволом. Они друг другу не мешают.
|
||||
Это снимает множество боли.
|
||||
Но есть и исключение. nfset-ы - аналог ipset-ов - нельзя использовать из другой таблицы. Потому если вам нужен ipset,
|
||||
создаваемый zapret скриптами, вам понадобится писать правила в той же таблице. Но нет никакой необходимости влезать в цепочки zapret.
|
||||
Создаете свои цепочки и хуки и делаете в них что угодно.
|
||||
|
||||
Плюс N2
|
||||
|
||||
Возможность выбора приоритета хука позволяет легко решить проблему хаотической и принудительной дефрагментацией L3 ipv6,
|
||||
без танцев с загрузкой модулей ядра со специальными параметрами или перекомпиляцией nftables-nft.
|
||||
Это же позволяет перехватить трафик после SNAT/MASQUERADE, что на iptables невозможно.
|
||||
Атаки на проходящий трафик, ломающие NAT, крайне затруднены на iptables.
|
||||
|
||||
Плюс N3
|
||||
|
||||
Наличие множеств (anonymous/named sets) позволяет не писать кучу однообразных правил там, где в iptables их пришлось бы написать.
|
||||
|
||||
Плюс N4
|
||||
|
||||
Если у вас есть nftables, то там наверняка есть уже все или почти все.
|
||||
Нет кучи разных модулей ядра и .so плагинов для iptables user-mode процесса.
|
||||
Отдельные модули ядра есть, но их меньше, чем в iptables, и openwrt их делит на меньшее число пакетов, большинство из которых
|
||||
и так ставятся по умолчанию. user-mode процесс nft и вовсе неделим. EXE-шник + lib.
|
||||
|
||||
Плюс N5
|
||||
|
||||
Пишут, что nftables работают быстрее. Но это не точно и зависит от много чего.
|
||||
В целом - чем меньше правил, тем выше скорость. Но в nftables правил можно писать меньше, значит скрость тоже может быть выше.
|
||||
У разработчиков есть идея перевести backend nftables на BPF, а это наверняка будет существенно быстрее.
|
||||
|
||||
|
||||
Выводы
|
||||
|
||||
Без больших листов все почти прекрасно. Но большие ip листы убивают все. Не для домашних это роутеров.
|
||||
А ipset-ы к nftables не прикрутить.
|
||||
Зато есть возможность задействовать более продвинутые атаки, конфликтующие с NAT, которые на iptables могут быть невозможны.
|
||||
Делать нечего. Openwrt отошел от iptables. С этим придется как-то жить.
|
||||
Поэтому пришлось сделать для openwrt поддержку и iptables, и nftables (только с версии openwrt 21.xx, в более старых будут проблемы).
|
||||
iptables можно задействовать на любой openwrt версии.
|
||||
Если используется fw3, применяется старый механизм интеграции в fw3.
|
||||
Если он не используется, то правилами iptables управляем как в традиционных linux системах - то есть с возможностью
|
||||
запуска и остановки, а скрипт запуска вносит в том числе и правила iptables.
|
||||
|
||||
На новых openwrt возможно снести nftables и firewall4 и установить firewall3 и iptables.
|
||||
Если вам никак без больших ip листов на слабой системе, это может быть единственным спасением.
