Remmina is a remote desktop client written in GTK+, aiming to be useful for system administrators and travellers, who need to work with lots of remote computers in front of either large monitors or tiny netbooks. Remmina supports multiple network protocols in an integrated and consistant user interface. Currently RDP, VNC, NX, XDMCP and SSH are supported.

Remmina is released in separated source packages:

“remmina”, the main GTK+ application
“remmina-plugins”, a set of plugins
