tsclient (taken from about dialog): Terminal Server Client is a frontend for rdesktop, vncviewer, wfica and xnest.
With it you can connect into a windows (rdp) or *nix (vnc) machine in an easy way. There also is a panel applet, which lets you connect quickly (just one click is necessary) into pre-configured machines.
It is a great tool, mainly in a networked environment. Its interface is very similar to that found on windows operating system. This is particularly cool for window users, they don’t have to learn how to use a new, different program.
I just started helping on tsclient development. I hope to improve this software, which i use every day in my work.
It has now a page on Sourceforge, with svn and bug tracking. So, bug reports and patches are more than welcome!
