I'm trying to run this script https://github.com/oblique/create_ap on startup on my RPi with this command: /usr/bin/screen -dmS ap /usr/bin/create_ap -m nat wlan0 eth0 RaspberryAP ******, but it doesn't do anything; it works when starting it manually via ssh, but sadly it's not starting on its own with this command. What did I do wrong?

Still, it doesn't start, but according to /var/log/syslog it also didn't have any errors

  • Where are you trying to start it from? – stevieb Aug 8 '15 at 16:38
  • @stevieb I'm using the /etc/rc.local file (in the line before exit 0) – Simon Aug 8 '15 at 16:39
  • Don't add to /etc/rc.local - that gets run at the end of every runlevel (including well before networking is up and going), suggest new script /etc/rc3.d/S99screen instead – steve Aug 8 '15 at 17:14
  • @steve Should I just add the command or use the skeleton? – Simon Aug 8 '15 at 17:23

Create a new startup script instead of adding to /etc/rc.local file. Doesn't have to be anything complicated. Example:

$ cat >/etc/rc3.d/S99screen
/usr/bin/screen -dmS ap /usr/bin/create_ap -m nat wlan0 eth0 RaspberryAP ******
$ chmod 755 /etc/rc3.d/S99screen

And then reboot to test.

  • I followed your instructions, but it seems like it's still not doing anything, because I started screen with -L (output logging) and still can't find any logfile – Simon Aug 8 '15 at 17:48
  • I just updated/upgraded with apt-get (for another reason) and when restarting apache, it seems like it's going through the startup scripts again, because there it tells me insserv: warning: script is corrupt or invalid: /etc/init.d/../rc3.d/S99create_ap – Simon Aug 8 '15 at 17:55
  • Oops, sorry, looks like template approach will be needed then. Take an existing script in /etc/rc3.d/, copy it to S99create_ap and edit to have your screen command in there, together with all the template headers. If then works I'll revise my answer accordingly. – steve Aug 8 '15 at 18:42
  • Sadly, that still didn't work; first I tried copying from ### BEGIN INIT INFO to ### END INIT INFO, which did nothing, and the I tried copying the whole file (I copied the cron script) and editing it accordingly (I'm still not sure about the DAEMON option). Didn't work either – Simon Aug 8 '15 at 18:53
