Permissions on /dev/null

Scott Hanson_1 — Tue, 07 Jan 2003 14:01:10 GMT

Hello.

The permissions on /dev/null are being reset during reboot. Does anyone know how to stop this (apart from explicitly resetting the permissions).

Thanks.

Scott

Hi,

What does your /dev/null look like after a reboot, and what are you resetting the permissions to?

We are resetting it to 666 but it keeps changing to 660.

Hi,

I did a 'chmod 777 /dev/null' and then executed a 'insf -e'. Now permissions are back to 666 ... Insf -e is sometimes called at reboot by ioinitrc (from inittab) but it depends on some tests.

Scott,

Maybe something is explicitly changing it. Try searching your startup scripts for a chmod:

find /sbin/init.d -exec grep -l "chmod" {} \;

You will find a few legitimate ones, but take a look at the ones you do get to see if any are altering /dev/null.
