Hi all, is there anyone successfully using the latest kernels (from
2.3.99-pre8 up to 2.4.0-test1) with amateur radio ax.25?
My configuration is a single tnc attached to a serial port with
kissattach.
This is the script: (/etc/network/interfaces) [this is a Debian Potato machine]
iface ax0 inet static
address 44.134.210.241
netmask 255.0.0.0
network 44.0.0.0
broadcast 44.255.255.255
# gateway 44.134.208.208
pre-up echo -n "Starting AX25 interface..."
pre-up kissattach -l -m 256 /dev/ttyS0 vhf 44.134.210.241
pre-up sleep 2
pre-up axparms -assoc ik5pvx-15 elena
pre-up echo "0" > /proc/sys/net/ax25/ax0/backoff_type
pre-up echo "1" > /proc/sys/net/ax25/ax0/ip_default_mode
pre-up echo "4" > /proc/sys/net/ax25/ax0/standard_window_size
pre-up echo "12" > /proc/sys/net/ax25/ax0/maximum_retry_count
# pre-up echo "512"> /proc/sys/net/ax25/ax0/maximum_packet_length <- non
supportato
up route add -host 44.134.208.208 dev ax0
up route add -host 44.134.208.176 gw 44.134.208.208
up route add -host 44.134.210.246 gw 44.134.208.208
up arp -H ax25 -i ax0 -s 44.134.208.176 ik5pwa-11
up arp -H ax25 -i ax0 -s 44.134.208.208 ik5pwa-11
up echo 0 > /proc/sys/net/ipv4/conf/ax0/log_martians
up ifup ax0:1
up ifup nr0
up ifup rose0
up ax25d -l &
up echo " done. (All radio interfaces are up)."
down echo -n "Stopping AX25 interface..."
down killall -9 ax25d || true
down ifdown nr0
down ifdown rose0
down ifdown ax0:1
down axparms -assoc ik5pvx-15 delete
post-down killall -9 kissattach
post-down echo " done. (All radio interfaces are down and kissattach removed)."
This is how the kernel sees it:
# ifconfig ax0
ax0 Link encap:AMPR AX.25 HWaddr IK5PVX-1
inet addr:44.134.210.241 Mask:255.0.0.0

TX packets:3577 errors:0 dropped:0 overruns:0 carrier:0

It seems to be working but with listen I can see a lot of [invalid]
packets:

obviously the connection is never set up
kissattach appears to be running:
# ps -ax|grep kiss
112 ? S 0:00 kissattach -l -m 256 /dev/ttyS0 vhf 44.134.210.241
and this is the content of the /proc files:

The last working kernel is 2.3.99-pre6, I never tested pre7 and pre9
on this machine.
I have a few days to help you developers track down this problem. I'm
not very good at using debugging tools but I'm eager to learn.
Thanks,
Pf
