cron job not executing (restart Wireguard connection)

Troubleshooting
1

Hi Forum! How are you? Long time no see…

I’m having trouble running the most simple cron job.

I’ve added the following by entering

crontab -e

(as root):

20 12 * * * /bin/date > /tmp/date.log

But nothing’s happening. I also tried putting a new file „date“ into /etc/cron.d/ but nothing’s happening as well.

The exact same thing on another server running Ubuntu (20.04.2 LTS) runs the job with no issues.

I’m lost, as the other jobs in cron.d/ (php, pihole, rsnapshot) run fine…

Thanks for any suggestions :slight_smile:

Okay… restarting the cron.service does the job for aforementioned command.

What I really want to do is resetting my Wireguard connection by doing:

36 17 * * * '/usr/bin/wg-quick down' && '/usr/bin/wg-quick up'

This does not work.

Hi,

I would recommend to restart the service instead of trying to sop/start Wireguard

/bin/systemctl restart wg-quick@wg0.service

Hi Joulinar,

thanks for your suggestion! This seems to have worked :slight_smile:

Could you enlighten me, why that’s the case compared to wg-quick up?

Thanks!

I guess you missed to specify the interface name for Wireguard to start/stop. At least the service is doing nothing else as you did, just with an interface name specified.

ExecStart=/usr/bin/wg-quick up %i
ExecStop=/usr/bin/wg-quick down %i
ExecReload=/bin/bash -c 'exec /usr/bin/wg syncconf %i <(exec /usr/bin/wg-quick strip %i)'

variable %i is specified within the service name wg-quick@wg0 right after @. Means, the interface name is wg0

Hah, your right! Thanks :slight_smile:
