Linux RH 7.1 KDE interface

[bdsimmns@memphis.edu]

I am new to cygwin, and have recently installed it on a couple of 
computers.  I can access our Sun and SGI workstations graphically.  I 
have not been able to open up a graphical window to Linux.  I am 
currently running a RH 7.1 cluster, and would like to be able to use a 
remote graphic interface.  Are there any services that must be running 
on linux?  Any help would be appreciated.
