#
# Access control file for XDMCP connections
#
# 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.
#
#* CHOOSER BROADCAST #any indirect host can get a chooser
#
# 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
#
#%hostlist host-a host-b
#* CHOOSER %hostlist #
#
# 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
#
# LISTEN * ff01:0:0:0:0:0:0:12b ff02:0:0:0:0:0:0:12b ff03:0:0:0:0:0:0:12b ff04:0:0:0:0:0:0:12b ff05:0:0:0:0:0:0:12b
