Thus, you may need to go digging through the files in your /etc directory
to find the correct setting. If you can’t find the setting, try using grep to
search for strings such as DISPLAYMANAGER or the name of the XDMCP
server that’s currently running.
Configuring an XDMCP Server
XDMCP servers, like most programs, can be configured. Unfortunately,
this configuration varies from one server to another, although there are
some commonalities. In the following pages, I provide some details for
configuring XDM, KDM, and GDM.
Configuring XDM
XDM is the simplest of the major XDMCP servers. It accepts usernames
and passwords but doesn’t enable users to perform other actions, such as
choose which desktop environment to run. (This must be configured
through user login files.)
XDM’s main configuration file is /etc/X11/xdm/xdm-config. Most
distributions ship with a basic xdm-config file that should work fine for
a local workstation. If you want to enable the computer to respond to
remote login requests from other X servers on the network or if you want
to verify that the system is not so configured, you should pay attention to
this line:
DisplayManager.requestPort: 0
This line tells XDM to not access a conventional server port. To
activate XDM as a remote login server, you should change 0 to 177, the
traditional XDMCP port. You must then restart XDM. When so
configured, users on other computers can initiate remote X-based logins
to your computer via XDMCP. This can be handy on local networks, but
it’s also a security risk, which is why the default is to not enable such
access.
