What programs do you run to administer the server?

You don't really need the whole desktop do you?  If not then you can
run GUI programs on your desktop using ssh and X, e.g.:-

    chris$ ssh -X esprimo
    chris at esprimo$ sqliteman
    Checking for  sqlite3 : 
    3.11.0 2016-02-15 17:29:24 3d862f207e3adc00f78066799ac5a8c282430a5f
    Checking for Qt version:  4.8.7 
    Initial DB:  "" 
    chris at esprimo$ 

This runs sqliteman on the *server* using your desktop for display,
the same can be done with just about any GUI program.
