So, what you're asking for is to run XDMCP on the gdm on the centos5 system, which it does support, just add an [xdmcp] section to /etc/gdm/custom.conf. However, the real question is how do you want to have clients contact gdm via XDMCP? X11 isn't a secure protocol, so just running 'X -query remotehost' isn't really the best idea. You'd have to open up the port on the server in the firewall too. I wouldn't suggest using this. It'd probably be better to use VNC and forward all traffic over SSH. -- Jonathan Billings <billings at negate.org>
