sshd not giving plogin prompt

[Dave]

Hello,
    I have a jailed ssh server among other things on a freebsd 5.4 box. I 
had to change the IP on it from 192.168.9.10 to 192.168.2.10. And now sshd 
on the jail won't let me log in. I've changed the ListenOn directive in the 
jails' sshd_config file from 192.168.9.10 to 192.168.2.10, as well as the 
jails ip in rc.conf. Trying to connect from windows securecrt just times 
out. Trying to connect from a unix box gives me the error: connection closed 
by 192.168.2.10. Any ideas? The jail is up, has been restarted and shows up 
in the jls output. I am stumped.
    On the subject of jails what devfs settings rules file should i use in 
rc.conf?
Thanks.
Dave.
