Crontab rolling back.

rmueller58 — Mon, 19 Sep 2005 09:03:21 GMT

root cron rollbacked to some unknown file this weekend. not sure what the hell is going on
I vi'd /var/tmp/root.cron last week

changed one parameter
read the file in with
crontab /var/tmp/root.cron

We reboot daily and run a backup daily upon system coming up.

Correct -------
30 23 * * * /pei/peitools/bin/reboot.sh
55 23 * * * /pei/peitools/bin/backups.sh

When we came in this morning, backups/exports had not run, and crontab -l output looked like this:

30 23 * * * /pei/peitools/bin/reboot.sh
55 23 * * 1-5 /pei/peitools/bin/backups.sh

Needless to say, I am a wee bit baffled and need to some info from the gurus. Any thoughts from you guys you all can pass along?

The /var/log/cron file has records of what happened with cron entries. Maybe someone/somehow the cron was replaced again.

Check the entries in the /var/log/cron file.

In the Linux version I use, i see a REPLACE entry when someone runs crontab filename.

Ivan,

the log gets overwrote on reboot by the looks of it.
