    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?:D

    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:

    - 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)

    - is sshd running (ps aux | grep ssh)
    - is sshd listening on the correct interface (netstat -tap | grep ssh), should be 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.
