Sounds like a SSH issue to me so have a read through [SOLVED] Remote Manager, Port 22 issue.

well thanks for the reply...but I'm bit confused..as mentioned in some security forums I changed the ssh port to some other port rather than the default port 22..as it's not very safe to be on the default port 22.can you please give some info on this...your help will be greatly appreciated
