AllowAddAllowAdd=true
If true, allow the user to add arbitrary hosts to the chooser.
This way the user could connect to any host that responds to
XDMCP queries from the chooser.
BroadcastBroadcast=true
If true, the chooser will broadcast a query to the local
network and collect responses.  This way the chooser will
always show all available managers on the network.  If you
need to add some hosts not local to this network, or if you
don't want to use a broadcast, you can list them explicitly
in the Hosts key.
MulticastMulticast=true
If true and IPv6 is enabled, the chooser will send a multicast
query to the local network and collect responses from the hosts
who have joined multicast group. If you don't want to send a
multicast, you can specify IPv6 address in the Hosts
key. The host will respond if it is listening to
XDMCP requests and IPv6 is enabled there.
MulticastAddrMulticastAddr=ff02::1
This is the Link-local Multicast address and is hardcoded here.
DefaultHostImageDefaultHostImage=<share>/pixmaps/nohost.png
File name for the default host icon. This image will be
displayed if no icon is specified for a given host. The
file must be in an gdk-pixbuf supported format and it must be
readable for the GDM user.
HostImageDirHostImageDir=<share>/hosts
Repository for host icon files. The sysadmin can place icons
for remote hosts here and they will appear in
gdmchooser.
The file name must match the fully qualified name (FQDN) for
the host.  The icons must be stored in gdk-pixbuf supported
formats and they must be readable to the GDM user.
HostsHosts=host1,host2
The hosts which should be listed in the chooser.  The chooser
will only list them if they respond.  This is done in addition
to broadcast (if Broadcast is set), so you
need not list hosts on the local network.  This is useful if
your networking setup doesn't allow all hosts to be reachable
by a broadcast packet.
ScanTimeScanTime=4
Specifies how many seconds the chooser should wait for
replies to its BROADCAST_QUERY.  Really this is only the time
in which we expect a reply.  We will still add hosts to the
list even if they reply after this time.
