Hi

Been a while since I last posted, but am in need of help.

Has anyone been able to get cron to burn a dvd at a specific time ??

Ive done as the man page says and suid the growisofs to root but this is still not helping me,

Ive tried various attempts at giving to many programs suid root and prob landed up compromising my machine but I still cannot get cron to automatically burn a dvd at a set time.

At the most I get the drive door to close, there is some activity and then nothing happens.

How do I grab the out put of cron to see what is going on
I have changed the log level in rc.M for crond to 1 and still there seems to be not very much logging going on.

mmm lost ...

Thanx

Could you post back a bit more of your approach to make this happen?

Assuming that you have written a shell-script to do some sort of backup, and then put that backup on a disc, does this script function by itself if run as the root user? If not, where does it fail?

I would be _very_ careful suid'ing programs to root that aren't meant for it - this is a potential huge security hazard...

Hi Yalla-One

Thanx for your interest in this problem

Ok basically I have made a small file that is executable this file contains the following


#!/bin/bash
/usr/bin/growisofs -Z /dev/dvd -R -J /home/backup/*.tar.gz
eject /dev/dvd


then in cron.daily I have a script that runs the above ( or at least it is supposed to )

Under the man for growisofs there is a mention that growisofs will not run as root unless you set uid to roof for growisofs.

I know that i am opening potential doorways but i have been trying to get this to run automatically for a while now and Im lost at the moment.

I have put the eject command above the growisofs command and the drive door does open so i do know that something is happening just when it gets to the burning part nothing happens.

Do you perhaps have any other ideas of how i can do this?

Thanx

I do mine in 2 steps, ie make the ISO with mkisofs and burn it with growisofs. Here are the commands I use:
My growisofs isn't suid, the permissions are:
The script containing that stuff runs out of cron on my setup with no problems, so I hope it's useful...

Thanx Gilead

I will give this a try
