cron jobs

    I've setup IPcop as our firewall and works very well but sometimes if the connection drops I have to hit disconnect and reconnect (from the web interface) or if I'm out of the office I just tell someone to reboot it using the power button...

    I've heard that it's pretty much a stripped down version of linux, so I've got in via ssh... which I did and it worked...

    but I'm not that experienced at command line linux and I wanted to create a simple cron job that would ping a site every 15 mins or so and if nothing came back to reboot the machine...

    Any advice would be good...

    Cheers

    Hi Colm,
    first make sure crond is installed and running.
    A ps aux should let you see it.

    If not, you'll have to fetch and install it,
    but I'd be surprised if it's not there.

    You can add a crontab entry using
    crontab -e
    and it should have a format like:
    0-59/15 * * * * root /usr/local/sbin/CheckOurLink

    I'd recommend against rebooting the system though.
    Find out what commands the system uses to restart
    the external network over the web interface, and just put those in the script.

    Hope that gets you started,
    keep us posted,
    NiallB
