The following is from /usr/share/gnome/help/gdm/C/daemonov.html: Remote displays can connect to the XDMCP port on the GDM host. gdm will grant access to hosts specified in the gdm service section in your TCP Wrappers configuration file. GDM does not support remote display access control on systems without TCP Wrappers. XDMCP support can be turned off completely, however. The Gnome help says that if gdm were compiled to support TCP Wrappers, the above feature would be supported. The question is, what was the gdm's compilation setting on Debian regarding this TCP Wrapper? TIA, Oki
