Thanks to a Sebastian’s post here, I noticed the existence of x2go. I’ve just tested it and I liked it a lot. X2go is a very nice way to access my linux desktop.
In order to install x2go server-side, on a Centos 6.4 I only needed theese commands:
yum update
wget -O /etc/yum.repos.d/x2go.repo http://download.opensuse.org/repositories/X11:/RemoteDesktop:/x2go/RHEL_6/X11:RemoteDesktop:x2go.repo
yum update
yum install x2goserver
then
vi /etc/group
to add the guys to be allowed to connect to their desktop. E.g.
x2gouser:x:298:joe,jane,jack,jasmine
The x2go windows client can be downloaded from http://code.x2go.org/releases/binary-win32/x2goclient/releases/.
