Task Scheduler - Restart VPN - Fail

General questions
1

Hello,

I am trying to use task schedule to accomplish a very simple task, restart vpn services every hour. I get an error when trying to use task scheduler . Commands, script and error below.

set system task-scheduler task restartvpn executable path ‘/config/scripts/restartvpn.sh’
set system task-scheduler task restartvpn interval ‘60m’

script

#!/bin/vbash
source /opt/vyatta/etc/functions/script-template
run restart vpn

error

Invalid task restartvpn: file /config/scripts/restartvpn.sh does not
exist or is not executable

Also it would be nice to have some examples on the wiki @
Task Scheduler — VyOS 1.4.x (sagitta) documentation

Version: VyOS 1.3.2
Release train: equuleus

Any ideas on why this is failing?

Thanks
-Nathan

What are the permissions on the script? It’s it set to executable? chmod +x /config/scripts/restartvpn.sh

As mentioned by zero1three013, make sure your script is executable.

and please update your VyOS version. 1.3.2 is almost as old as me… :slight_smile:

That was it, I just needed to set to executable. Thanks all

One last note, make sure you add exit to the end of your script. Otherwise you’ll get a large number of fuse mountpoints that can eventually lock up your config unless you reboot.

I ended up using bash and AWK to check the status of the connection table and restart vpn only if there was not an established connection to the desired endpoints

#!/bin/bash

Check for established connections to specific IP addresses

connections=$(sudo /opt/vyatta/bin/vyatta-op-cmd-wrapper show conntrack table ipv4 | awk ‘$2 ~ /^(10.10.10.1|10.20.10.1)/ && $6 ~ /ES/’)

If no connections are found, restart VPN

if [ -z “$connections” ]; then
echo “No established connections found to 10.10.10.1 or 10.20.10.1. Restarting VPN…”
sudo /opt/vyatta/bin/vyatta-op-cmd-wrapper restart vpn
else
echo “Established connection(s) found:”
echo “$connections”
fi

sudo chmod +x /config/scripts/restart-vpn.sh
exit
configure
set system task-scheduler task restartvpn executable path ‘/config/scripts/restart-vpn.sh’
set system task-scheduler task restartvpn interval ‘1’
