+</para>
+
+<important>
+<para>
+Note that &ktalkd; is designed to run on a single-user workstation, and
+shouldn't be run on a multi-user machine: since it reads users'
+configuration files, users can get the <command>talk</command> daemon to
+run any command, which is particularly dangerous. Do not use &ktalkd; if
+you create accounts on your machine, to people you don't fully trust.

+
+<para>
+In this document, if somebody wants to talk to you, you are designated
+as the <quote>callee</quote>.

+the user one, in its home folder. The sitewide one has to be manually
+edited by the administrator, but there is now a configuration dialog for
+the user one. It's called <command>kcmktalkd</command> and can be found
+in the &kcontrol; after installing &ktalkd;. On non-&kde; systems,
+&ktalkd; will read <filename>/etc/talkd.conf</filename>.

+<para>
+To use &ktalkd;, you need a <command>talk</command> client. The
+text-based <command>talk</command> is available on most &UNIX; systems. Try <userinput><command>talk</command> <replaceable>your&lowbar;username</replaceable></userinput> to see what happens when you
+receive a <command>talk</command> request.
+</para>
+
+<para>
+You can also try the answering machine the same way: initiate a
+<command>talk</command> to yourself, ignore the announcement twice, and
+you'll see the answering machine.
+</para>
+
+<para>
+There is a <command>talk</command> client with a graphical interface for
+&kde;, &ktalk;. It's not yet shipped with &kde; packages, but you can

+<question>
+<para>
+Why doesn't <systemitem class="username">root</systemitem> receive &kde;
+announcements?
+</para>
+</question>
+
+<answer>
+<para>
+Because this would be security hole, with the current user
+detection. You can bypass the limitation by adding two lines in
+<command>xdm</command> config files (which are the same as &kdm; ones).
+</para>
+
+<note>
+<para>
+The S.u.S.E &Linux; distribution includes those lines by default.
+</para>
+</note>
+
+<para>
+Those config files are normally in a folder such as <filename
+class="directory">/etc/X11/xdm</filename>, or <filename
+class="directory">/usr/X11R6/lib/X11/xdm</filename> on other
+systems. The following supposes that they are in <filename
+class="directory">/etc/X11/xdm</filename>, so you might have to
+translate them for another folder.</para>
+
+<para>Here is what you have to do:</para>
+
+<procedure>
+<step>
+<para>Edit the file <filename>Xstartup</filename>, or create it, (in the
+<command>xdm</command> config folder) so that it reads:
+</para>
+<screen>#!/bin/sh
+/etc/X11/xdm/GiveConsole
+sessreg -a -l $DISPLAY -x /etc/X11/xdm/Xservers $USER</screen>
+</step>
+<step>
+<para>and the file <filename>Xreset</filename> so that it reads:
+</para>
+<screen>#!/bin/sh
+/etc/X11/xdm/TakeConsole
+sessreg -d -l $DISPLAY $USER</screen>
+</step>
+<step>
+<para>
+Make sure that <filename>xdm-config</filename> make reference to those
+two files:
+</para>
+<screen>DisplayManager._0.startup: /etc/X11/xdm/Xstartup
+DisplayManager._0.reset: /etc/X11/xdm/Xreset </screen>
+</step>
+</procedure>
+
+<para>
+This will make &kdm; (or <command>xdm</command>) log
+the user into utmp, which is the right thing to do. It's not up to
+&konsole;, nor <command>xterm</command>, to log the user, but to
+<command>xdm</command> and &kdm;, in my
+opinion. However, this will not log the user as an X user when using
+<command>startx</command>... Any hint about that ?
+</para>
+</answer>
+</qandaentry>
+
+<qandaentry>
+<question>
+<para>
+Why don't I, as a normal user, receive &kde; announcements?
+</para>
+</question>
+
+<answer>
+<para>
+If you're running a &Linux; system (with <filename
+class="directory">/proc</filename> enabled), this behavior is a
+bug. Please send me a description of it so that I correct it.
+</para>
+
+<para>
+If you're running &Linux; 2.0.35, this is a known bug in the kernel,
+which doesn't let <systemitem class="username">root</systemitem> read
+<filename class="directory">/proc</filename>. The solution is the same
+as in the previous question, provided that you run
+&kdm; or <command>xdm</command> to log into X. Or
+upgrade!
+</para>
+
+<para>
+Otherwise, this is normal. &ktalkd; can't find the user, as &kde;
+doesn't log him into utmp and the &Linux; based (<filename
+class="directory">/proc</filename>) detection is disabled. The solution
+is the same as in the previous question, provided that you run
+<acronym>kdm</acronym> or <acronym>xdm</acronym> to log into X. Another
+solution is to make sure you always have an
+<application>xterm</application> running.

+
+<qandaentry>
+<question>
+<para>
+How do I get debug output from &ktalkd;?
+</para>
+</question>
+
+<answer>
+<para>
+As it is a daemon, there is no debug output on standard output. To get
+debugging output (for instance before submitting me a bug report!),
+update the lines in <filename>inetd.conf</filename> which launches
+&ktalkd; and &kotalkd; to be:
+</para>
+
+<screen>talk dgram udp wait root /usr/sbin/tcpd /opt/kde/bin/ktalkd -d
+ntalk dgram udp wait root /usr/sbin/tcpd /opt/kde/bin/ktalkd -d</screen>
+
+<para>Notice the <option>-d</option> option.
+</para>
+
+<para>
+Then edit <filename>/etc/syslog.conf</filename> to add the following
+line:
+</para>
+
+<screen>*.* /var/log/all_messages</screen>
+
+<para>To make it work, you then have to restart <command>inetd</command>
+and <command>syslogd</command>:</para>
+
+<screen><prompt>%</prompt> <userinput><command>killall</command> <option>-HUP inetd</option></userinput>
+<prompt>%</prompt> <userinput><command>killall</command> <option>-HUP syslogd</option></userinput></screen>
+
+<para>Finally, run a <command>talk</command> session and see the result
+in <filename>/var/log/all&lowbar;messages</filename> </para>
+
+<para>When submitting a bug report, never forget to include the
+debugging output, but also &ktalkd;'s version number and the
+<command>./configure</command> output. Thanks.</para>
