Cron Package not running command?
I have a fully working PF Sense implementation, though I have an issue of undetermined origin, which requires me to bounce my WAN interface occasionally (once every week or two).
I found a script that I have validated works for this purpose, and I have installed the Cron service, with a view to running it every 5 minutes to check if it can ping outside, and if not, bounce the interface.
The script works perfectly if I run it from diagnostics –> command prompt (using the command```
The script does not, however, appear to be executed by cron. My cron setup looks like: !(http://cron.PNG) I have also tried chaging the command to``` sh /usr/local/bin/pingtest.sh
I have executed```
chmod +x /usr/local/bin/pingtest.sh
When run from Cron, the script won't have a PATH or some other environment variables. Programs called inside the script must use a full path to their executables.
If you need help checking that, we will need to see the contents of your pingtest.sh script.
Thanks for the reply. The pingtest script is one that I actually got on here, which seems to be working according to the thread: https://forum.pfsense.org/index.php/topic,17243.msg89348.html#msg89348
If you prefer not to follow the link, the code is:

Rebooting..." >> $LOGFILE /sbin/shutdown -r now >> $LOGFILE exit 1 fi COUNT=`expr $COUNT + 1` done
I haven't modified the script, other than to change the IP addresses for pinging to 126.96.36.199 and 188.8.131.52 (Google nameservers), and to change my WAN interface to re1.
At the very least, ping should be /sbin/ping, and expr should be /bin/expr
There may be more but I didn't look over every line. You'll need to fix any place that runs a command without specifying the full path.
