[gentoo-user] sshd won't restart on remote system

[gentoo-user] sshd won't restart on remote system

[Grant]

After updating to the latest stable x86 openssh and merging config
files on my remote system, I get:

# /etc/init.d/sshd restart
* Stopping sshd ... [ !! ]

There is nothing in /var/log/sshd/current.  Does anyone know what I should do?

Sometimes ssh won't restart if it's being used, possible after an openssl 
update I'm not sure.
Try this

(sleep 5 ; /etc/init.d/sshd restart) &

then logout, and 5-6 seconds later try to login, if it worked ssh can now be 
restarted while you're logged in as normal.

You could stop the sshd process manually with kill or similar (I use
htop). (Careful though, you don't want to kill your current session,
just the daemon listening for new connections!) Then you can "zap" the
service and start it as normal.

Or you could reboot the host, and (assuming it's in your default
run-level) sshd will start on boot.

I could reboot, but how can I be sure sshd will start again?  The fact
that it's not stopping makes me wonder if there is something wrong.
If it doesn't start I'm locked out of the remote system.

You may be interested in :
/etc/init.d/sshd reload

I get:

# /etc/init.d/sshd reload
 * Reloading sshd ...
No /usr/sbin/sshd found running; none killed. [ ok ]
# /etc/init.d/sshd restart
 * Stopping sshd ... [ !! ]

That is scary. Can you do equery f openssh, also do a simple ls
/usr/sbin/sshd

When is the last time you did an etc-update?

Thanks for helping me out with this.  I re-emerged openssh and now
sshd restarts just fine.

"/etc/init.d/ssh zap" should do it. If "/etc/init.d/ssh start" then still 
does not work, you may need to kill -9 the running sshd server. You may 
do this, running ssh sessions will not be terminated by this.

You can also start/test the new sshd parallel to the running old one, but 
on another port: /usr/sbin/sshd -p 12345. Then connect with ssh -p 12345.

I just had the same problem. After upgrading from openssh-4.7_p1-r6 to 
5.1_p1-r1, /etc/init.d/sshd did not work. Configs had been updated 
already. I emerged 5.1_p1-r1 again, and now /etc/init.d/sshd works fine.
