[GRLUG] Port Forwarding

[L. V. Lammert]

Ran into an interesting problem today, .. on BSD and CentOS 5.4, when a
reverse SSH tunnel is setup it binds to all IPs on the host:

tcp          0      0  *.2210         *.*   LISTEN
tcp6         0      0  *.2210         *.*   LISTEN

With a more modern Linux, the *SAME* command binds to 127.0.0.1 ONLY:

tcp        0      0 127.0.0.1:2205          0.0.0.0:*               LISTEN
tcp        0      0 ::1:2205                :::*                    LISTEN

What must be done on a modern Linux kernel so that incoming connections
can also use the port?

	Thanks!
