SSH to remote server

[jaredgalen]

I need to ssh into a remote machine.
the problem is that I am behind a proxy that blocks port 22.
I have been looking at port forwarding but I can't quite get my head around it.

Do I need to make the remote machine listen on a different port so that I can connect or something? Or is their some jiggery pokery I can do here behind the proxy to connect to the remote machines on port 22?

Its a good idea anyway to run ssh on some port other than 22 since so many scriptkiddies will try and attack that common port.

find out what port you can get out on

let's assume you will use 8181

On the remote machine run the following



iptables -t nat -A PREROUTING -i your_input_interface -p tcp --dport 8181 -j REDIRECT --to-port 22

On the client machine

ssh -p 8181 remotehost.domain.com


Otherwise edit sshd.conf file to permanently change SSH port.

What mrregan is telling you is true; if yo leave a public server with port 22 open you will find several huundred login attempts in the morning in your logwatch message.
