Yeah... I agree this is NOT obvious nor intuitive > netrom FH2LOR-2 svnnah 235 netrom /etc/ax25/nrports Looks ok. > axport0 5 192 100 0 /etc/ax25/nrbroadcast looks ok but maybe try renaming this to say "axport". Maybe the trailing 0 is messing things up. Be sure to update the /etc/ax25/axports file with the same name too > axport0 FH2LOR-1 115200 254 8 AX.25 over LoRa Looks ok though what is the RF link speed you're using? I've seen some funny buffering problems in the past so I actually use 9600 baud to the TNC for a 1200baud RF link > Unfortunately it still fails: > > root@savannah:~# modprobe netrom > root@savannah:~# nrattach netrom > nrattach: cannot find free NET/ROM device What do you have in /etc/ax25/nrbroadcast Are you sure the netrom module is loaded? Check: $ lsmod | grep netrom netrom 47709 2 ax25 65384 16 netrom,mkiss The way I load my system via my packetrig.sh startup script, I use: $NRATTACH -i $AMPRIP -m 236 $VHFD710NRPORT I would also recommend you to show each of the commands you're using to load up your stack: - Are you using the mkiss approach with PTYs or using kissattach directly? - Are you seeing any errors when you run each command? See http://www.trinityos.com/HAM/CentosDigitalModes/usr/local/sbin/packetrig.sh for the script but it is a pretty complex script for new Linux users. --David KI6ZHD
