Does anyone have any experience with X.25 on Linux?
unortunately not. However, I know that a number of HAM radio operators are
still using the AX.25 in Linux. It has not received a lot of maintenance
in the last 15+ years or so, but there's some new grant to get that fixed:
The net/x25 directory still exists. It looks like the application-side
interface uses a sockets based API.
If you grep for ARPHRD_X25, you can find the only drivers that work with that code:
* drivers/net/wan/hdlc_x25.c
This is a backend for the generic HLDC / synchronous WAN device code.
I'm using this HDLC code (with frame relay on top, not X.25) even in
production setups together with DAHDI on Digium and other cards. So at
least up to that HDLC layer we know it works.
You could follow
with the only difference that you have to use 'sethdlc hdlc0 x25' to
tell the HDLC WAN code to put X.25 on top.
* drivers/net/wan/lapbether.c
This is the LAPB-over-Ethernet driver you already hinted. I've never
used it, but looking at the code it seems that it automatically creates
a "lapb*" interface for each ethernet interface in your system.
I wondering if / hoping I can establish an XOT connection with ?strid's
Telebahn and then switch (term?) to multiple things local to my LAN.
I've not seen any XOT code in Linux, so there doesn't seem to be a
straight-forward way to hook those two up.
