croc
File transfer over parallel TCP with a rendezvous server.
This is more or less a Golang port of magic-wormhole except it probably isn't secure.
Install
go get github.com/schollz/croc
Basic usage
Send a file
On computer 1 do:
$ croc -send somefile
Your code phrase is now limbo-rocket-gibson
waiting for other to connect
Receive a file
Just type croc and you'll be prompted for the code phrase. Use the code phrase to get the file.
$ croc
What is your code phrase? limbo-rocket-gibson
0s [====================================================] 100%
Downloaded somefile!
Advanced usage
Make your own rendezvous server
On some server you have, your-server.com, just run
$ croc -relay
Now, when you use croc to send and receive you can add -server your-server.com to use your rendezvous server.
Known issues / To-Do list
- Is it secure? not sure
- Need to clear clients who disconnect before sending/receiving
- Handle file sizes < BUFFERSIZE * numberOfConnections (currently 4096 bytes)
