Running a program automatically by the clock?

orange400 · 07-11-2004, 04:50 PM

I run a RH9-based text-only server and I wanna run chkrootkit every now and then automatically. The program basically checks for worms and traces of aliens trying to gain root access of the server. How would I be able to make my server automatically take this into action at power-on? I would like it to run the program every hour, day, or something like that.

Thanks!

use cron

Okay, I man paged it and googled it, then added this to my crontab:

0 * * * * root /usr/src/chkrootkit*/chkrootkit

How's this look? If I did it correctly, it should be set to run every hour.

How can I make crond pick up on this addition to the configuration? Is there a way I can restart it or does it just figure it out on its own?

1. "Cron" should figure it out on its own.

2. Typically the easiest way to update the crontab (on a per-user basis) is:

a) Log in (or "su") to the user meant to execute the cron job
b) "crontab -e" to edit the file

Anyway, it looks like your syntax is correct, and that it should work as you expect.
