Hunter's comment

Working as a sysadmin requires someone to be able to access a node remotely, that's where the remote desktop application needs to be.

Remmmina is one of the remote desktop applications that can access any operating system and from anywhere using Linux.

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. (Source)
