Need to automate kill wpa_supplicant on resume on 15.04 with systemd

  • 772

I need to run

sudo killall wpa_supplicant

automatically after resume. Unfortunately on 15.04 with systemd it isn't possible with scripts.

How this may be automated?

scripts

    You need to place your scripts in:

    /lib/systemd/system-sleep/

    An example script based on one from the Arch wiki (systemd sleep Hooks):

    #!/bin/sh
case $1/$2 in
  pre/*)
    echo "Going to $2..."
    # better to put `exit 0` if no pre suspend action required
    ;;
  post/*)
    echo "Waking up from $2..."
    # Add whatever you want run post suspend (ie resume)
    killall wpa_supplicant
    ;;
esac

    Dont forget to make your script executable!

    sudo chmod a+x /lib/systemd/system-sleep/your-script

    See man systemd-sleep for more details.

    There is no need for sudo as your script will be run as root.
