I’m trying really hard to get iperf to launch at boot on my Z83-II. I’ve tried 3 different tutorials and have yet to have it work. Is there something in the structure of Dietpi I’m unaware of? 2 of the tutorials were pretty much the same and one had my put the startup script in /etc/intit instead of /etc/init.d

Can you post a bit more info on what you’ve tried and your startup script?

Hi John, first I tried this in the /etc/init.d dierctory under the name “iperf3”
#!/bin/bash
/usr/bin/iperf3 -s &
I also tried this more complex script under the /etc/init directory under the name iperf3.conf
description “Iperf 3 Upstart Script”
author “Author”
start on filesystem or runlevel [2345]
stop on shutdown
expect fork
script
exec /usr/bin/iperf3 -s -D
echo $$ \> /var/run/iperf3.pid
end script
pre-start script
echo “[`date`] Iperf 3 Server Starting” \>\> /var/log/iperf3.log
end script
pre-stop script
rm /var/run/iperf3.pid
echo “[`date`] Iperf 3 Server Stopping” \>\> /var/log/iperf3.log
end script
iperf3 runs perfectly if I launch it manually with
iperf3 -s

I take it you have done the obvious:
# chmod 755 /etc/init.d/iperf3
and
# update-rc.d iperf3 defaults

I did but being unsure I did it again and still will not start at boot… not a big issue since I can manually start it…

Just a thought on this could it be that the script is running before the network is up?
Have you thought of trying to start it using a Systemd script?
