/dev/null permission denied
 

Hi,
I was messing around with x-configurations and setting up of a dual head, however now, when i restart X, i cant login to X. It gives an error --/dev/null permission denied. I can login from root though. the permissions of /dev/null is crwx------ .If i change it to crwxrwxrwx then i can login from other users
to X . But when i restart the computer the permissions revert back to crwx------.

How do i change the permissions of /dev/null to crwxrwxrwx permanently? Where will all these settings be saved?

As you didn't mention your distro, let's assume it uses udev
you have to look at /etc/udev/permissions.rules, the line should be:
KERNEL=="null", MODE="0666"

Could also be this, depending on your udev version:
KERNEL="null", MODE="0666"

I use ubuntu 6.06.1 LTS. The settings of /etc/udev/rules.d/permissions.rules is :
KERNEL=="NULL" ,MODE="0666". The udev service is on in all the runlevels. But i am still facing the same problem. Why?

Maybe another rule is overriding this one. ??
Try udevtest to check how rules are applied.

Are you using an initrd? I'm not sure when /dev/null is created but you should also check the rules in the initrd.

Can you be more specific? How to use udevtest? I am using initrd...
