Default Can't run TCP/IP through AX.25 using Linux

Dont know about you guys, but since I still use an old 8 bit
Commodore128 computer I do all my packeting with the software
DIGICOM128 AND IT WAS WRITTEN BY THE GERMANS WAY BACK.
I use only the VHF band for military packet relays from
Ft Huachuca Az to Schofield Bks here in Honoululu.

Hi again,

I did some tcpdump and it definitly looks like an ARP problem.

# ./tcpdump -envi ax0
tcpdump: listening on ax0, link-type AX25 (AX.25), capture size 96

I'll get in contact with the creator of this kernel.
