This section has some example configurations that are useful for
various setups.
</p><div class="sect2"><a name="terminallab"/><h2 class="sect2 title"><span class="title"><span class="label">11.1. </span>Terminal Lab With One Server</span></h2><p xmlns:msg="http://www.gnome.org/~shaunm/gnome-doc-utils/l10n" class="para">
Suppose you want to make a lab full of X terminals that all connect
to one server machine. So let's call one X terminal
<span class="filename" style="font-family: monospace; ">xterminal</span> and let's call the server machine
<span class="filename" style="font-family: monospace; ">appserver</span>. You install GDM on both.
</p><p xmlns:msg="http://www.gnome.org/~shaunm/gnome-doc-utils/l10n" class="para">
On <span class="filename" style="font-family: monospace; ">appserver</span> you enable XDMCP, so you have
<div class="screen block-indent"><pre class="screen">[xdmcp]
Enable=true
</pre></div>
If you want no local screens here, you can then
make the <span class="filename" style="font-family: monospace; ">[servers]</span> section empty.
</p><p xmlns:msg="http://www.gnome.org/~shaunm/gnome-doc-utils/l10n" class="para">
On the <span class="filename" style="font-family: monospace; ">xterminal</span> you disable XDMCP (you don't
want anyone to connect to the xterminal really). You will add a
server type perhaps called <span class="filename" style="font-family: monospace; ">Terminal</span> as follows:
<div class="screen block-indent"><pre class="screen">[server-Terminal]
name=Terminal server
command=/path/to/X -terminate
flexible=false
handled=false
</pre></div>
This definition should in fact be included in the standard
configuration file. Notice that we made the
<span class="filename" style="font-family: monospace; ">handled</span> key false since we don't want GDM to
handle this server localy. Also note that we have not yet added the
<span class="filename" style="font-family: monospace; ">-query</span> argument, you can add that here, or in the
<span class="filename" style="font-family: monospace; ">[servers]</span> section. We'll define our local
servers as follows:
<div class="screen block-indent"><pre class="screen">[servers]
0=Terminal -query appserver
</pre></div>
This will run a direct XDMCP query to the server named
<span class="filename" style="font-family: monospace; ">appserver</span>.
</p></div><div class="sect2"><a name="terminallabtwo"/><h2 class="sect2 title"><span class="title"><span class="label">11.2. </span>Terminal Lab With Two Or More Servers</span></h2><p xmlns:msg="http://www.gnome.org/~shaunm/gnome-doc-utils/l10n" class="para">
Suppose you want to make a lab full of X terminals that all connect
to some choice of servers. For now let's make it
<span class="filename" style="font-family: monospace; ">appserverone</span> and
<span class="filename" style="font-family: monospace; ">appservertwo</span>. Again we'll call our example X
terminal server <span class="filename" style="font-family: monospace; ">xterminal</span>. The setup on both
servers is the same as with the case of one server in the previous
section. You do not need to explicitly enable indirect queries on the
server since we'll run the choosers locally on the X terminals.
</p><p xmlns:msg="http://www.gnome.org/~shaunm/gnome-doc-utils/l10n" class="para">
So on the <span class="filename" style="font-family: monospace; ">xterminal</span> you again disable XDMCP.
You will add a server type perhaps called <span class="filename" style="font-family: monospace; ">Chooser</span>
as follows:
<div class="screen block-indent"><pre class="screen">[server-Chooser]
name=Chooser server
command=/path/to/X
flexible=false
chooser=true
</pre></div>
And again this definition should in fact be included in the standard
configuration file. Notice that we made the
<span class="filename" style="font-family: monospace; ">chooser</span> key true here. This will run the XDMCP
chooser for this server, and when the user chooses a host GDM will run
a query for that host. Then we will define our local servers as
follows:
<div class="screen block-indent"><pre class="screen">[servers]
0=Chooser
</pre></div>
</p><p xmlns:msg="http://www.gnome.org/~shaunm/gnome-doc-utils/l10n" class="para">
The XDMCP chooser on the X terminal will normally give a broadcast
query to see which servers exist on the network. If the two servers
are not reachable by a broadcast query, you must add them by hand to
the configuration file. So in the <span class="filename" style="font-family: monospace; ">[chooser]</span>
section you would have:
<div class="screen block-indent"><pre class="screen">Hosts=appserverone,appservertwo
</pre></div>
and any other servers you wish the users to be able to connect to.
</p><p xmlns:msg="http://www.gnome.org/~shaunm/gnome-doc-utils/l10n" class="para">
Sometimes you may want to run the chooser on the server side however.
Then what you want to do is to run a configuration similar to the
previous section about the one server configuration with XDMCP
indirect queries enabled on <span class="filename" style="font-family: monospace; ">appserver</span> and on the
X terminals you'd have
<div class="screen block-indent"><pre class="screen">[servers]
0=Terminal -indirect appserver
</pre></div>
This way for example you only have to maintain one
<span class="filename" style="font-family: monospace; ">Hosts</span> entry. However as a disadvantage then,
the <span class="filename" style="font-family: monospace; ">appserver</span> must then always be available. So
it's not good for situations where you want to have several servers
and not all of them have to be on all the time. You could also have
one of the X terminals handle indirect XDMCP queries and serve up the
chooser to the other X terminals.
