CRON task not running!

Gertjan

#bash

No really.
Use any other shell script file to see what I mrean.
Is bash installed ? As far as I know, no.

#!/bin/sh

If bash is installed :

#!/usr/local/bin/bash

because bash would be here : /usr/local/bin/

I found logger, it's in in /usr/bin/

@gertjan Sorry man im a little basic when it comes to scripting.

#!/bin/sh
/sbin/ifconfig hn1 down

would take the interface down correct?

Gertjan

would take the interface down correct?

Yes.
A command typed on the command line, can also be used in a script file **.

When I created a text file called /root/test like :

#!/bin/sh
/usr/bin/logger "Disable interface"
/sbin/ifconfig em0 down
/usr/bin/logger "Enable interface"
/sbin/ifconfig em0 up
/usr/bin/logger "Done"

And I make it executable

chmod +x  /root/test

Now I can

/root/test

In the system log, I saw :

and it broke my connection for a moment, as my WAN interface is em0 for me, it went down and up.

** edit : if the command is interactive, things get a bit more complicated.

@gertjan great thank you!

Then I need to execute the script from the Cron task? How can I call the script?

Thanks again appreciate your help

@deanfourie There is a cron package to manage cron jobs. As I recall if you manually add cron jobs, they are lost on reboot.

deanfourie

@steveits Yup, CRON package is installed.

Only thing I need to get right is to execute the script from the Cron job.

Gertjan

On the main cron page, you have 2 buttons :

How cron works, what you have to enter as the "time" needs some reading.
Any "FreeBSD cron man page" will do here.

@gertjan Turn out this morning at 11 AM when I was away the interface went down.

Turns out I was using 12hour time format not 24hour.

FFS

So, after all that the CRONs do work.

Gertjan

Turns out I was using 12hour time format not 24hour.

Yes, a day has 24 hours.

@gertjan Thanks for that

Thanks for your help!
