My company uses a telnet/ssh client for windows called putty and since they only make it for windows i need something like it. They use the putty client to access the companies wireless internet system on that has an assigned ip. Actually they only use the ssh part of the client so i guess that woudl be fine for me too. If my mac will do it itself that would be great too. I just am completely lost anything would be great.
and if you need to create ssh tunnels, have a look at SSH Tunnel Manager
tunnel manager is not really necessary if your already using the terminal.
ssh -L 5901:localhost:5902 serverip.
The above is an example of creating a listing port making a tunnel for the above port this what people use for tunneling to initiate a vnc session for example.
