Terminal Server Client is a frontend for rdesktop
Terminal Server Client (tsclient) is a frontend for rdesktop. It supports most of the rdesktop 1.1/1.2 arguments, can read .rdp files in the Microsoft Unicode format, writes new .rdp files in ASCII (which can also be read by the Microsoft RDP Client), and looks and functions very much like the Microsoft RDP Client. It features a Gnome panel applet to quickly launch saved rdp files.
