Hello,

I am a web developer and use SSH/Telnet to access our web server. Over the past few weeks I've been unable to connect except for very brief periods. The normal response is 'error: the network connection has timed out' indicating that the server is uncontactable.

The server is actually fine and I can reach it by pinging, ftp (port 21), http (port 80) and mysql (port 3306). Only on port 22 do I have this problem. Other users of the server can connect using this method with no problems.

I have checked and disabled all firewalls and connected to the cable modem directly (I normally use a Netgear 4-port broadband router). This is also not a PC problem as it occurs on all machines I have at home (none of which have firewalls installed).

Does anyone know if NTL is blocking this port? Is anyone else aware/experienced this problem? I think it may be at their end but I haven't been able to find any information about this.

I have also asked this question on ADSL Guide - they pointed me to the information in the link below showing which ports NTL blocks. Is it the case that 22 has been added to this list?

Thanks in advance,

Paul.
