It can be easy to link an ax25 interface to Direwolf. This makes it possible to use RMSGateway, Uronode etc with Direwolf.
In this script Direwolf is started with the -p option. With the -p option a virtual tnc is created. /tmp/kisstnc.
With mkiss a kiss connection is made on the /tmp/kisstnc. With kissattach the PTY is connected to the ax25 interface.
Fist edit the file axports in /etc/ax25
pd9q@pd9q:/etc/ax25 $ cat axports # /etc/ax25/axports # name callsign speed paclen window description # ax0 PI1LAP-9 19200 255 7 RMSGateway pi1lap-10
Config the direwolf.conf file to set the right audio device and ptt port. Save file to /etc/ax25/direwolf.conf

Run the script
#!/bin/bash

echo "Starting direwolf"
direwolf -t 0 -c /etc/ax25/direwolf.conf -p &
#Check if Direwolf is running
sleep 5
if [ -z "`ps ax | grep -v grep | grep direwolf`" ]; then
echo -e "\nERROR: Direwolf did not start properly and is not running, please review direwolf.conf"
exit 1
fi
echo "Installing one KISS connection on PTY port /tmp/kisstnc"
mkiss -s 19200 -x 1 /tmp/kisstnc > /tmp/unix98
#This creates a PTS interface like "/dev/pts/3"
export PTS0=`more /tmp/unix98 | grep -w /dev | cut -b -11`
echo "PTS0 device: $PTS0"
kissattach $PTS0 ax0 > /tmp/ax25-config.tmp
awk '/device/ { print $7 }' /tmp/ax25-config.tmp > /tmp/ax25-config1-tmp
read Device < /tmp/ax25-config1-tmp
Let’s check if everything went well.
pd9q@pd9q:~ $ ps ax 1015 ? Ss 0:00 mkiss -s 19200 -x 1 /tmp/kisstnc 1025 ? Ss 0:00 kissattach /dev/pts/2 ax0
Try it out…

Now it’s possible to setup RMSGateway or Uronode of whatever you want.
