I have installed Ubuntu server 12.04 with ssh. I have configured the network, i think correctly. I am unable to access through putty. Any ideas what to check or where to go for a solution?
Yes, what is the error message Assuming you have neither configured a firewall on your client (dropping outgoing connections) nor on your server (dropping incoming ones), you could try the following: client ------ - putty's error message?! - can you ping it? (in hope server replies to icmp, thus the fw comment above) - can you access any other open ports on that server - when accessing via DNS, does the dns record resolve to the correct ip (nslookup / dig) server ------ - is sshd running (ps aux | grep ssh) - is sshd listening on the correct interface (netstat -tap | grep ssh), should be 0.0.0.0:22 or <yourserversip>:22 - are incoming packets dropped (e.g. tail -f /var/log messages while trying to access)
Well, that was the problem I did not get an error message at all, just a blank screen. Thank you very much for your reply, I found the problem tho. It was an IP issue.
