NordVPN is a pretty good service, however, it occasionally updates the client and the connection goes down. Since the client is so transparent, it can unnoticed for days before I catch up. It seems like a good idea to have a script to outsource that vigilance.

The plan:

  1. Write a script to check NordVPN status and report on the issue if everything is not fine.
  2. Run that script periodically.


$ vim bin/nvpn-monitor

status_connected=$(nordvpn status | grep "Status: Connected" | wc -l);

export DISPLAY=:0.0
export $(grep -z DBUS_SESSION_BUS_ADDRESS /proc/$(pgrep "mdm")/environ )

if [[ $status_connected = '0' ]]; then
  notify-send "NordVPN is disconnected" -u critical•


  • The export commands are needed for notify-send to know which session user to notify. Nicked it off the internets. Depending on what session manager you’re using you might need to change the mdm bit there.

Run periodically

I briefly thought about making a daemon, but seems overkill. Just add this to cron.

$ crontab -e

* * * * * /home/gregpk/bin/nvpn-monitor 2> /home/gregpk/cron.txt >> /home/gregpk/cron.txt

Note: I output all cron scripts to the same file so that they can be debugged properly if they fail.

That’s it! This will now
