# To control Direct and Broadcast access:

#
|
|
# pattern
|
|
#
|
|
# To control Indirect queries:
|
|
#
|
|
# pattern list of hostnames and/or macros ...
|
|
#
|
|
# To use the chooser:
|
|
#
|
|
# pattern CHOOSER BROADCAST
|
|
#
|
|
# or
|
|
#
|
|
# pattern CHOOSER list of hostnames and/or macros ...
|
|
#
|
|
# To define macros:
|
|
#
|
|
# %name list of hosts ...
|
|
#
|
|
# To control which addresses xdm listens for requests on:
|
|
#
|
|
# LISTEN address [list of multicast groups ... ]
|
|
#
|
|
# The first form tells xdm which displays to respond to itself.
|
|
# The second form tells xdm to forward indirect queries from hosts matching
|
|
# the specified pattern to the indicated list of hosts.
|
|
# The third form tells xdm to handle indirect queries using the chooser;
|
|
# the chooser is directed to send its own queries out via the broadcast
|
|
# address and display the results on the terminal.
|
|
# The fourth form is similar to the third, except instead of using the
|
|
# broadcast address, it sends DirectQuerys to each of the hosts in the list
|
|
# The fifth form tells xdm which addresses to listen for incoming connections
|
|
# on. If present, xdm will only listen for connections on the specified
|
|
# interfaces and/or multicast groups.
|
|
#
|
|
# In all cases, xdm uses the first entry which matches the terminal;
|
|
# for IndirectQuery messages only entries with right hand sides can
|
|
# match, for Direct and Broadcast Query messages, only entries without
|
|
# right hand sides can match.

#* #any host can get a login window
|
|
|
|
#
|
|
# To hardwire a specific terminal to a specific host, you can
|
|
# leave the terminal sending indirect queries to this host, and
|
|
# use an entry of the form:
|
|
#
|
|
|
|
#terminal-a host-a
|
|
|
|
|
|
#
|
|
# The nicest way to run the chooser is to just ask it to broadcast
|
|
# requests to the network - that way new hosts show up automatically.
|
|
# Sometimes, however, the chooser can't figure out how to broadcast,
|
|
# so this may not work in all environments.

|
|
# If you'd prefer to configure the set of hosts each terminal sees,
|
|
# then just uncomment these lines (and comment the CHOOSER line above)
|
|
# and edit the %hostlist line as appropriate
|

|
# If you have a machine with multiple network interfaces or IP addresses
|
|
# you can control which interfaces accept XDMCP packets by listing a LISTEN
|
|
# line for each interface you want to listen on. You can additionally list
|
|
# one or more multicast groups after each address to listen on those groups
|
|
# on that address.
|
|
#
|
|
# If no LISTEN is specified, the default is the same as "LISTEN *" - listen on
|
|
# all unicast interfaces, but not for multicast packets. If any LISTEN lines
|
|
# are specified, then only the listed interfaces will be listened on.
|

|
|
# IANA has assigned FF0X:0:0:0:0:0:0:12B as the permanently assigned
|
|
# multicast addresses for XDMCP, where X in the prefix may be replaced
|
|
# by any valid scope identifier, such as 1 for Node-Local, 2 for Link-Local,
|
|
# 5 for Site-Local, and so on. The default is equivalent to the example shown
|
|
# here using the Link-Local version to most closely match the old IPv4 subnet
|
|
# broadcast behavior.
|
|
#
|
|
# LISTEN * ff02:0:0:0:0:0:0:12b
|
|
|
|
# This example shows listening for multicast on all scopes up to site-local
