Pre Script: Thanks Murphy. It's obvious that I would find the docs that I read last night /after/ I hit send on the message.

I'm working to find the user space commands and utilities to bring the interface(s) up and how to use it (them).
It seems as if the README file in the x25-utils-2.1.20 package has the most directly useful information.

To start up X.25 under Linux
----------------------------
First start up your LAPB interface. At present the only such interface is the LAPB over ethernet device. Firstly get your ethernet card up and running as normal using ifconfig.
Next bring up the lapb0 device with:
ifconfig lapb0 up
Next set up your X.25 routes. I would guess at this stage you just want all X.25 packets to go out via via lapb0, so just do:
x25route add 1/0 lpab0
To make sure its all OK do:
cat /proc/net/x25*
You will see alsorts of useless information !
To set up an X.25 TELNET link, start up telnetd on the remote machine with the command:
./telnetd <address>
Where <address> is the X.121 address that you want telnetd to listen on.
On the local machine use the command:
./telnet <locaddr> <remaddr>
Where <locaddr> is the local X.121 address to be used for the outgoing connection, and <remaddr> is the X.121 address of the remote copy of telnetd.
If you are running Linux/X.25 to another machine running Linux/X.25 without an intermediate machine operating as a DCE, it will not work. What you need to do is build *one* of your machines with the LAPB layer operating as a DCE. To do this edit the linux/include/net/lapb.h and change the line:
#define LAPB_DEFAULT_MODE (LAPB_STANDARD | LAPB_SLP | LAPB_DTE)
to:
#define LAPB_DEFAULT_MODE (LAPB_STANDARD | LAPB_SLP | LAPB_DCE)
and rebuild your kernel. I hope that this will be a run-time option eventually, but at the moment this is the only way to do it.
