To setup ssh server on FreeBSD is really easy..

just edit the /etc/rc.conf and put:

sshd_enable="YES"

save

and restart/start the sshd services:

freebsd8# /etc/rc.d/sshd restart
Stopping sshd.
Starting sshd.

check if the daemon@process us really up and running:

freebsd8# ps -aux | grep sshd
root      36557  0.0  1.3  9400  3268  ??  Is    2:35PM   0:00.06 sshd: trunasuci [priv] (sshd)
trunasuci 36560  0.0  1.3  9400  3276  ??  S     2:35PM   0:00.46 sshd: trunasuci@pts/0 (sshd)
root      36610  0.0  1.2  6676  2928  ??  Is    2:47PM   0:00.00 /usr/sbin/sshd
