Hi all,

I had ssh working, but it seems to have stopped. I restarted the service and that is running. DOes someone know how to install another ssh client or maybe what I should check for?

I believe this occured after I installed vsftpd

Thanks

Which Linux distribution are you using? Version?

If ssh stopped, it has to do with ssh server not client. It doesn't have anything to do with vsftpd as well so I am a little confused to as what you are actually trying to do.

If it is a problem of service not starting by itself after rebooting, the solution should be simple enough but is distribution dependent.

Redhat familly command would be
chkconfig sshd on

Ubuntu family
update-rc.d sshd defaults

Debian, newest release, I thing its 6.03; I did reboot and that didnt work either.....

the service is starting but for some reason i cant access the server from ssh any longer. are there any logs to show where the issue may be?

I did not tell you to reboot. I said it appears that sshd doesn't start after reboot.

Issue command to check
netstat -antpu | grep 22

See if there are any sshd daemons listening

Issue command
Ubuntu family
update-rc.d sshd defaults

And reboot again to see if it works after reboot

I did run this command and it is not listening on these ports; here is the error when trying to start the service: sshd/var/run/sshd must be owned by root and nt group or world writable

Hi Farzanj-

with the help above I found it was a permission issue. So this helped me find the issue. I then applied these commands to fix the permissions:

chown root:root /var/empty/sshd
chmod 711 /var/empty/sshd
/etc/init.d/sshd start
