DireWolf/Linpq with Systemd.

I have a bad time behind me, I have had a lot of arguments with Systemd to start DireWolf and Linpq when booting 🙂
If you like Systemd, you can read some about it here https://en.wikipedia.org/wiki/Systemd

I want Linbpq to run under /dev/tty2 and DireWolf under /dev/tty3. This is because if I login remotely I can view the monitor from DireWolf with “conspy”. “conspy 3” Hit esc a few times to leave conspy.

Systemd does not want to accept the start line with >/dev/tty3 &

ExecStart=/usr/local/bin/direwolf -c /home/pd9q/direwolf.conf -l /home/pd9q/direwolf.log >/dev/tty3

This upper start line does not work.

So I had to come up with something else for that. So i wrote a start file. “direwolf.start”

cd /usr/local/bin
./direwolf -c /home/pd9q/direwolf.conf -l /home/pd9q/direwolf.log >/dev/tty3

Now i wrote a unit file to start DireWolf on boot.
/etc/systemd/system/direwolf.service

[Unit]
Description=DireWolf Deamon
After=network.target
After=sound.target
After=syslog.target

[Service]
Type=simple
ExecStart=/bin/bash /home/pd9q/linbpq/direwolf.start

[Install]
WantedBy=multi-user.target
Alias=direwolf.service

Now DireWolf is starting very nice on /dev/tty3

I had the same problem with Linbpq, which I solved in the same way.

Linbpq start file “runbpq”

cd /home/pd9q/linbpq
sudo ./linbpq  >/dev/tty2

The unit file “linbpq.service”

[Unit]
Description=Linbpq Daemon
After=network.target
After=direwolf.target

Ok, let’s see if it is running

Now have a look at /dev/tty2 “conspy 2”
