I rebooted my server yesterday. Today three of four clients still function as normal. The client I use cannot access the server. The services used are SSH (PuTTY), Squid, Cups and Webmin. All nothing doing and generally it appears that everything times out.
If I ping the server IP this does not seem to do anything .... I have not waited for more than a few minutes to see if it eventually times out but immediately it just hangs...
I do not understand what is wrong since the other clients are working normally. No changes have been made.
How do I fix this or at least work out what is the problem?
