the sshd config is the default ubuntu config file.
I just added these lines:
Banner /etc/ssh/sshd_banner.txt
PermitRootLogin no
MaxAuthTries 5
LoginGraceTime 1m
UsePAM yes
applied all updates yesterday.

Title:
Service ssh stop/start/restart hangs
Status in “openssh” package in Ubuntu:
Confirmed
Bug description:
When using "service ssh," all of the actions cause the service process
to hang, with varying results on the sshd process.
root@localdev14:~# ps -ef | grep ssh
root 28264 1 0 15:39 ? 00:00:00 /usr/sbin/sshd -D

root 28444 28418 0 15:48 pts/0 00:00:00 grep --color=auto ssh
A trace on /usr/sbin/service shows that it's hanging at /sbin/stop;

Restarting the service gets a different error;
root@localdev14:~# bash -x /usr/sbin/service ssh restart 2>&1 | tee /tmp/ssh.restart
++ basename /usr/sbin/service

^C
root@localdev14:~# ps -ef | grep sshd
root 28264 1 0 15:39 ? 00:00:00 /usr/sbin/sshd -D

root 28495 28418 0 15:56 pts/0 00:00:00 grep --color=auto sshd
As you can see from the PID, the sshd service was in fact not stopped.
If you kill the sshd manually, and try to use the service command to
start the process, that hangs as well, although the process is
actually started;
root@localdev14:~# bash -x /usr/sbin/service ssh start 2>&1 | tee /tmp/ssh.start
++ basename /usr/sbin/service
+ VERSION='service ver. 0.91-ubuntu1'
++ basename /usr/sbin/service
+ USAGE='Usage: service < option > | --status-all | [ service_name [ command | --full-restart ] ]'
+ SERVICE=
+ ACTION=
+ SERVICEDIR=/etc/init.d

+ case "${1}" in
+ '[' -z ssh -a 1 -eq 1 -a start = --status-all ']'

+ '[' -z ssh ']'
+ '[' -z '' ']'
+ ACTION=start
+ shift
+ '[' 0 -gt 0 ']'
+ '[' -r /etc/init/ssh.conf ']'
+ which initctl
+ initctl version
+ grep -q upstart
+ case "${ACTION}" in
+ exec start ssh
^C

root 28515 28418 0 15:59 pts/0 00:00:00 grep --color=auto sshd
I've been able to reproduce this problem both after a reboot, and from the console, with no user sshd process running.
On a side note, the sshd_config file appears to be sane. At least no
errors are being presented, so I don't believe this is OpenSSH
related.
