mtr
 

Hi
i have a script to run a couple of commands but it doesnt run mtr
from the cron jon
when i run the script manualy it works but when its in the cron it doesnt
here is the command
mtr -n -p -c 2 192.168.2.1 >> /file/
has anyone had this same problem and can anyone help

As a general rule, you have to use the full path of the commands inside a cron job, since the crontab has a very limited environment and the PATH variable is usually limited to /bin:/usr/bin. Put the full path to mtr and it should work from the crontab as well.

Hi
Thanks for that its works but it keeps running even with the option for only 1 count
/usr/sbin/mtr -r -n -p -c 1 192.168.2.2

Right...based on your command line, it would. Did you read the MAN page for mtr?

-i is the interval in seconds, between ICMP requests. 1 second is the default.

Could it have something to do with cron job iterations? The -c 1 option runs the command a single time.
