I'm trying to use Fugu (a Mac OS X GUI client for SSH and SFTP) but I cannot, for the life of me, figure out how you're supposed to start an SSH session with a remote server. It says that you have to create a new tunnel and turn on remote login and stuff like that, but that doesn't make any sense to me when I can use the Terminal and ssh to the other server just fine, without any of that stuff. The problem with that approach is that I then cannot figure out how to start an SFTP session with the server to transfer files to and from it. Complicating matters somewhat is the fact that the server I ssh into is a "gatekeeper" server, which serves to authenticate users, so they can then rsh into another server to get actual work done. I need to be able to start an SFTP session with this second server, but I cannot figure out how to do it once I'm in via SSH.
