<sect1> lan_remotedialing: How can I allow the users in my LAN to trigger
a dial out via the ISDN card(s) in my Linux PC?
<label id="lan_remotedialing">
<p>
For this you need two pieces of software. At the computer where the ISDN-line
is connected you need to install a <tt>dial daemon</tt>. The dial daemon
will execute any dial commands given from a <tt>dial frontend</tt> located on
a different computer on the LAN. You have several options to choose a dial
daemon and dial frontend.
<enum>
<item>
At first you can use the free software <tt>smpppd</tt> (SuSE Meta PPP
Daemon) from SuSE as the dial daemon. smpppd gets used in the SuSE distribution
for all ISDN, Modem and DSL connections. You can connect to smpppd locally or
over a LAN via different dial frontends and trigger dial-out, hang-up and so
on. The most known dial frontend is kinternet a small applet for the KDE
Kicker. Others are the qt-only qinternet and the command line tool cinternet.
Unfortunately there is no frontend for Windows or Mac OS available.
Obviously this is the easiest way if you already have SuSE installed on the
server, and all other involved computers are also based on Linux (installation
of the dial frontend should not be too difficult with non-SuSE distributions).
Some more hints:
<itemize>
<item>The software is available in SuSE-Linux within the packages smpppd,
kinternet and qinternet, see <url url="http://www.opensuse.org">
<item>In order to allow smpppd listening into the LAN change the following
two options in /etc/smpppd.conf (see also "man smpppd.conf"):
<code>
open-inet-socket = yes # (default is no)
bind-address = &lt;IP&gt; # IP of the LAN-network-card of the dial in server;
# default is listening on all network cards (!)
</code>
<item>On the client side you can either enter the dial server via GUI or via
/etc/smpppd-c.conf (see also "man smpppd-c.conf").
</itemize>
<item>
Another free software solution working the same way is <tt>LineControl</tt>.
It has a dial daemon (linesrv) which you can configure dialing different
connections (similar to smpppd) be it ISDN, Modem, DSL or another dial-out
connection. Dial frontends are available for Linux (one for KDE and one for
Gnome), Windows and Java.
Some more hints:
<itemize>
<item>The software and tutorials can be found at
<url url="http://linecontrol.srf.ch/">
<item>The config files is located at <tt>/etc/linesrv.conf</tt>
(the relevant configuration options are similar to that of smpppd)
<item>Several dial and hang up scripts where you can define the system
commands how to dial/hang up certain connections are below
<tt>/etc/linesrv/</tt>
<item>In order to have the linesrv daemon running at system start of your
server you also need to enter it in your system start configuration.
<item>On the client side you now can enter the dial server via GUI in one of
the frontends and dial/hang up a connection configured at the server.
