exactly the same for me.
It was, when an OM, who was new to APRS, was connectecting my old kernel 2.4
box directly with his packet program.... oopsa ;)

But this kind of trouble could be solveable.

I really think, ax25 interfaces should not depend on an IP Address,
because there are reasons you may not need / want IP. Or IPv6. Or .. .

Without IP, you also have not nasty things (on misconfiguration)
like ARP, Samba Broadcasts, or the newest hypes: AVAHI mDNS broadcasts.

For this reason, kissattach's IP-address argument is now optional.
And: the brought up interface has not the "BROADCAST" flag set;
who needs broadcast, and likes kissattach to do the job, could use
the new "-b" option.
