sockstat

List open Internet or UNIX domain sockets. More information: https://man.freebsd.org/cgi/man.cgi?sockstat.

  • View which users/processes are [l]istening on which ports:

sockstat -l

  • Show information for IPv[4]/IPv[6] sockets [l]istening on specific [p]orts using a specific [P]rotocol:

sockstat -{{4|6}} -l -P {{tcp|udp|sctp|divert}} -p {{port1,port2...}}

  • Also show [c]onnected sockets, not resolving [n]umeric UIDs to user names and using a [w]ider field size:

sockstat -cnw

  • Only show sockets that belong to a specific [j]ail ID or name in [v]erbose mode:

sockstat -jv

  • Display the protocol [s]tate and the remote [U]DP encapsulation port number, if applicable (these are currently only implemented for SCTP and TCP):

sockstat -sU

  • Display the [C]ongestion control module and the protocol [S]tack, if applicable (these are currently only implemented for TCP):

sockstat -CS

  • Only show Internet sockets if the local and foreign addresses are not in the loopback network prefix 127.0.0.0/8, or do not contain the IPv6 loopback address ::1:

sockstat -L

  • Do not show the header ([q]uiet mode), showing [u]nix sockets and displaying the inp_gencnt:

sockstat -qui
