Re: Help with X.25 tests

[Bahri Okuroglu <bahrio@yahoo.com>]

First, you need to use slattach to set the line
discipline of the port, you're interested in, to X25.
After that you'll have a network interface like
x25asy0, which you should take up and set some routes.


In the kernel, LAPB is configured as DTE by default (
http://lxr.linux.no/source/net/lapb/lapb_iface.c#L135
and http://lxr.linux.no/source/include/net/lapb.h#L58
). If you need your box to act as DCE, you either need
to change this default behavior or enable the user to
be able to change it. 

I'm not an expert on these issues, but the code looks
like for testing issues as noted at the top of the
source code. For example it does not implement CRC and
does only byte stuffıng, not bit stuffing. Do you
know that Cisco can talk to it? 

Good luck,
