XDMCP and TCP wrapper
Last modified: Wednesday, December 2, 2015 9:21 AM
In order for Xmanager to connect via XDMCP , UNIX/Linux machines utilize XDM daemon's UDP port 177. Therefore, configuration in the TCP Wrapper is not possible. However, if using GDM hosts.deny and hosts.allow may be used.
/etc/hosts.allow, /etc/hosts.deny files should be configured as such:
*:* > Deny service to all hosts
gdm:* > Allow GDMservice to all hosts
