I have a script that starts my broadband connection at start-up and I want to make it start at resume from suspend.

My script's is /usr/local/bin/start_my_connection

it contains:

sleep 10
nmcli nm wwan on
nmcli con up id "reber connection"`

What should I do to make it run using systemd?

  • Don't know if it's relevant to systemd. Why not try putting it into /etc/pm/sleep.d/, and check what happens. – mikewhatever Aug 15 '15 at 9:42
  • no it should be at /lib/systemed/systemed-sleep/ but don't know how to make it work after that. – RonnieDroid Aug 15 '15 at 9:44
  • Try this question - though a deleted answer on it suggests elsewhere using another location due to this . – Wilf Aug 15 '15 at 9:45

There are two approaches to choose from:

Using the /lib/systemd/system-sleep/ directory:

Create another script called 00start_my_connection:

if [ $1 = post ] && [ $2 = suspend ]
then /usr/local/bin/start_my_connection

$1 is "post" on resume/thaw and "pre" otherwise. In either case, $2 contains either "suspend", "hibernate", or "hybrid-sleep". If you want the script to also run on thaw from hibernation, leave out && [ $2 = suspend ].

Ensure this script is executable by using chmod a+x 00start_my_connection

Move this script into /lib/systemd/system-sleep/ using

sudo mv 00start_my_connection /lib/systemd/system-sleep/

Using service files:

Create the file /etc/systemd/system/start_my_connection.service:

Description=Run start_my_connection



Uncomment all lines if you also want the script to run on thaw from hibernation. Then install the service file with:

sudo systemctl enable start_my_connection.service
  • hi, the first method didn't work for me, the second one when i try to install the serves it says no such file or directory – RonnieDroid Aug 15 '15 at 16:24
  • Does the file /etc/systemd/system/start_my_connection.service exist? – Martin Thornton Aug 15 '15 at 16:29
  • sorry my bad, i place it at /bin/systemed not /etc/systemed . now it's installed but still doesn't reconnect after suspend. – RonnieDroid Aug 15 '15 at 16:46
  • What is the output of journalctl -eu start_my_connection – Martin Thornton Aug 15 '15 at 16:53
  • it's a long list, post it here? @martin – RonnieDroid Aug 15 '15 at 16:59

Create a file 01myscript in /etc/pm/sleep.d/ directory.

Contents of that file should be:


case $1 in 
    thaw|resume) /usr/local/bin/start_my_connection

Make that script executable: sudo chmod +x /etc/pm/sleep.d/01myscript.

Try to suspend

  • Is reboot or restart sleep service needed? – WinEunuuchs2Unix Oct 28 '18 at 16:05
  • @WinEunuuchs2Unix I've not used this method for a long time but if I recall correctly no reboot or service restart was required. – Sergiy Kolodyazhnyy Oct 28 '18 at 22:06
  • I was working with this after comment and can confirm you don't need to restart systemd-suspend.service – WinEunuuchs2Unix Oct 28 '18 at 22:37
