Re: x.25 status in kernel

Hi,

For the other end of XoT, as far as I know it can be another linux box,
or some vendors packaged linux boxes, or a cisco router. There could be
more I haven't had to work on it for a year or so. When we did it, an
x.25 network was being virtualized with XoT to get rid of the old x.25
network hardware. The applications and end point hardware/firmware
stayed x.25, and we used XoT to join it to the network. In this scenerio
XoT made sense, as an added bonus on the cisco side XoT works with
normal IOS, XoE/llc2 requires an enterprise IOS.

If your migrating from solstice without changing the network, and
already have something for XoE, the x.25 over llc2 will be the one to
look at, from memory solstice didn't do XoT. I noticed Venkat just
posted this
"I want to make two Linux systems communicating through X.25 suite.
I am successful in sending data through X.25 PLP over lapb over 
Ethernet. (by using X25 socket API, x25route and lapb0 virtual
interface)" Sounds like what you need.

Your right on the x25tap. It seems to work well enough for the moment,
but should be migrated from the obsolete interface. 

Cheers,
Andrew
