The rdesktop utility for Linux allows easy remote desktop access from a Linux machine. Type:
sudo apt-get install rdesktop to install this useful utility and then type:
rdesktop 192.168.100.5 to connect to a remote machine.
Specify the username with the -u parameter:
rdesktop -u homer 192.168.100.5.
If you wish to use RDP in full-screen; enabling a high-resolution display, then use the -fP parameter:
rdesktop -u homer -fP 192.168.100.5
This is a very easy way to connect to a Windows machine using terminal services instead of having to be seated in front of it.
