通过 SCTP 的 SSH(使用 Socat)

# on remote server
# assuming you want the SCTP socket to listen on port 80/SCTP and sshd is on 22/TCP
$ socat SCTP-LISTEN:80,fork TCP:localhost:22

# localhost
# replace SERVER_IP with IP of listening server, and 80 with whatever port the SCTP listener is on :)
$ socat TCP-LISTEN:1337,fork SCTP:SERVER_IP:80

# create socks proxy
# replace username and -p port value as needed...
$ ssh -lusername localhost -D 8080 -p 1337
