I get
tcp6 0 0 :::22 :::* LISTEN
on benden and
tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN
on landing

benden:~# ps -ef | grep sshd
root 5557 1 0 Feb15 ? 00:00:00 /usr/sbin/sshd
root 12597 17238 0 16:49 pts/2 00:00:00 grep sshd
landing:~$ ps -ef |grep sshd
root 7615 1 0 13:26 ? 00:00:00 /usr/bin/sshd
root 7671 7528 0 16:48 tty1 00:00:00 grep sshd
I suspect some of the differences are due to the fact I have sid
running on benden but squeeze on landing
(in case anyone wonders about hostnames they are taken from Anne
McAffreys Pern stories, so have a fort and a telgar as well)
