I am the admin of a private server and I'm pretty new to administration. SSH was working fine until I upgraded to 14.04. Something went wrong with the upgrade so I downgraded to 13.04. Now SSH doesn't work, that is, when a remote tries to connect, the server doesn't respond.
- I used
ifconfigto double check the server IP.
- The network card (wireless) works fine. I can
ping 188.8.131.52without a problem.
- If I
sudo service ssh statusI see a process. When I
ps -ef | grep sshdI see the process running.
- Doing a
netstat -lnI can see
tcp ... 0.0.0.0:22.
/etc/ssh/sshd_configshows password auth is enabled.
- There is a
~/.sshdirectory with a
'known_hostsfile in it.
- On the server, I can
ssh localhostand get a response.
Anyone know what could be happening? What should I do next?
