Enabling remote desktop under Linux (XDMCP)

categories:

Under CentOS 4,

edit /etc/X11/gdm/gdm.conf

Search for the section [XDMCP] Change the line “Enable=false” to “Enable=true”

Restart X

You should now be able to remotely connect using X-Win32 or such

You may need to configure iptables to allow connections : iptables -A INPUT -p udp -m udp --dport 177 -j ACCEPT iptables -A OUTPUT -p udp -m udp -m state --state RELATED,ESTABLISHED -j ACCEPT

Pay close attention to the security risks, don’t open it wide to the internet
