Question:

Why does my xterminal log me out of an X session after
about five minutes from an Interactive host?


Answer:

By default xdm sessions on the console do not get pinged.  However when
xterminals are added to the net a new feature in X2.0 is that xdm will
ping for the presence of these new nodes.  If ping does not respond in
time the xdm session manager will determine that the node has died or
locked up and will then close all the processes related to that login
session, finally re-starting the xgetty login process.  Setting
pingInterval and pingTimeout to 0 will force xdm not to issue pings.  By
default xdm is supplied with the ping variables set to 5 minutes.  So,
please add these lines to your /usr/lib/X11/xdm/xdm-config file:

	DisplayManager*pingInterval: 0
	DisplayManager*pingTimeout: 0
