Title: Setting up sshd to run on additional ports?
Post by: jitspoe on May 22, 2008, 01:56:24 AM

So it seems a lot of ports are blocked at my new job and I can't connect to anything via SSH on port 22.  Is there a way to set up the server so it will run on additional ports.  Also, how can I check which ports I have available on my end?

If you are running Ubuntu:
System > Administration > Network Tools

There is a tab called "Port Scan."  Have it scan 127.0.0.1.

For the alternate port, open up the ssh config file (/etc/ssh/ssh_config) and modify line 39 to your needs.

If it's Windows, could you call

Code: [Select]

netstat or

Code: [Select]

netstat -an from command prompt?

I seem to have written down

Code: [Select]

netstat -an |find /i "<port>" as a search method for open ports, but all it does is search the I drive, lol.

Oh, forgot he needed the list of ports Windows side.  >.<

Hmm, I guess searching for open ports on my machine doesn't really help much as they get blocked by the router or something else further up.  We have a local IRC server I can connect to, but I can't connect to external IRC servers on the same port.
