I need to access SSH at College (where I am right now) for future use for a College Project. Unfortunately, whenever I try to use PuTTy, I receieve a "connection refused" error (attempting to connect to port 22). Is there any way I can workaround this?

The systems here use Windows XP and I'm trying to connect to SSH for a server running CentOS. Anyone have any clue? Sorry if this is the inappropriate forum to post in, seeing as I'm effectively trying to figure out how to bypass port blocks.

If you have access to the server configurations, you can route port xxx to port 22 internally so you can bypass the restriction completely.

I do, however I'd rather keep the original port, plus I'm unsure of which ports are actually open (other than 80).

Do you have access to the firewall(s)/router(s) ? You need to set up port forwarding to be allowed in. You'd be able to see all the available connection ports on there as well.

To my server's firewall, I do. But no access to any control interfaces at College as I'm just a Student.

Do you want to SSH into the server via an external (WAN) network or via the internal (LAN) network?

WAN. My server's firewall is properly configured to accept connections on port 22.

If you want to access the server from the external network your going to have to ask them to open up port 22 on their network firewall/router and have it forward to your server's IP address
