Unable to remote log in to linux via Putty
I am trying to log onto a remote server in my school from home. I have done it via putty from other computers within the sch.
Problem is I am unable to log in from home. After keying in the ip address, selecting port 22 and ssh, I don't even get a chance to type anything. Just a blank black screen for like 10secs followed by a error message - Network error. Connection timed out.
Any idea why. The server is running so am assuming some kinda setting issue coming from my side.
I'm very new to linux. Bear with me pls. Thanks for assistance.
