Hello everyone, hi Richard,
a couple of remarks, regarding this issue.
a) "duplication" on the air
Indeed I discovered the problem exactly "on the air", at least using
software "TNCs".
I have some logs taken from Direwolf or MIXw2 showing duplication being
sent on the radio channel (I can share, if somebody needs), and also
some reports from Canada (thanks to VE1JOT) reporing practical
impossibility to transmit TCP over AX25 on HF channels due to the
duplication.
b) 6PACK problem
I was curious to understand if the problem affects also 6PACK, but I was
unable to test it : on Debian Wheezy, switching kissattack in 6pack mode
always crashes the kernel, on Jessie it doesn’t, but no data exchange is
possible and - worst - sniffing the interface always show "kiss" frames
instead of 6PACK frames (at least in the ARP dialogue). This happens
also on Fedora21. I opened a ticket on the Jessie side on Saturday.
Thank-you
Regards
73, Ugo
