XDMCP and TCP wrapper

Last modified: Wednesday, December 2, 2015 9:21 AM

PROBLEM DESCRIPTION

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.



RESOLUTION

/etc/hosts.allow/etc/hosts.deny files should be configured as such:

/etc/hosts.deny
*:*     > Deny service to all hosts

/etc/hosts.allow
gdm:* > Allow  GDMservice to all  hosts
