    cron jobs not running

    ViX 6.0.003

    I'm having a problem with a couple of cron timers that I've set not running. I can run them from the ViX script runner with no problems.
    Permissions for the scripts in /usr/script/ & /usr/scripts/ and the scripts in cron.hourly/daily are set at 755 and the crontabs root file is also 755.
    I've checked /var/log/messages and seeing a lot of errors:

    Code:
    Dec  4 18:53:25 sf8008 authpriv.notice passwd[3317]: pam_unix(passwd:chauthtok): password changed for root

    Does anyone have any ideas?

    messages.log


    EDIT: It seems to be something to do with my /etc/cron/crontabs/root file. I've deleted it and set my jobs up manually in the cron timer plugin and seems to be running.
    Maybe the one in my settings backup is corrupted in some way but it looks okay?

    Code:
    @reboot /usr/script/skyscraper.sh
@reboot /usr/script/skypicker.sh
0 */3 * * * /usr/script/skyscraper.sh

    The file permissions were probably too high, cron is very security conscious.

    See what they're set to now.

    This is the code that produces the message:

    Code:
                   if ((statbuf.st_mode & 07533) != 0400) { 
                        log_it(uname, pid, "BAD FILE MODE", tabname, 0); 
                        close(crontab_fd); 
                        return (-1);
    So the file:
    • must have no special bits set (setuid/setgid/sticky)
    • must not be executable by anyone
    • must only be readable by the owner.

    600 would be normal.

    I think my original problem was a corrupt crontabs/root file. If I tried to open the cron manager it was crashing the box.
    I've set my cron jobs up manually in cron manager and set permissions to 600 and all is working again.
    Thanks for the advice guys
