I have different hosts I need to communicate with.
I use ssh for linux boxes, rdesktop for windows boxes, NX for connecting to my workstation at work, and scp for file transfer between linux boxes.
All tools that works well.
Then I stumbled over remmina, which seems to combine all these protocols in one tools, and even better uses a tab’ed approach for the open communication windows.

I have problems with the authentication for NX, but a little more experimenting will hopefully solve that.
I know that the Unix/Linux philosophy is a single task for a single tool, which will do the work well, but I love to have my many ssh connections as tabs in a single window, so philosophy should not stop you from working efficient!
