/dev/null chmod reset after reboot

[simba]

Hello all.

Can't solve one problem which causes exim to fail.
Every time server is restarted or at some interval /dev/null permissions reset to rw r r .
chmod 666 /dev/null
cmod a+rw /dev/null

After running any of these commands permissions will be:
crw-rw-rw- 1 root root 1, 3 Apr 13 2012 /dev/null

But not for long.

Exim's paniclog complains about it. Anybody having same issue?

Hello,

Is it a VPS? OpenVZ virtualization?

Hi,

It's a VPS. Reading on google, i came open udev.rules.
In /ect/udev/rules.d/ there is file 60-raw.rules but it's commented out.
I created 40-basic-permission.rules with:
KERNEL=="null", MODE="0666"

but still the same. After reboot it resets to crw-r--r-- 1 root root 1, 3 Apr 13 2012 /dev/null


Thanks for help

P.S. What is the answer for

one three five seven ? Next number in the sequence should be nine, no?

You might need to delete MAKEDEV then

p.s. make sure you've got a ready backup copy of your VPS

It's live system. I don't want to go extreme

For now i put

chmod 0666 /dev/null

in etc/rc.local

Thanks.
Could admins make me verified user?

Introduction: static /dev

In order for container to work, some nodes should be present in container's /dev. For modern distributions, udev is taking care of it. For a variety of reasons udev doesn't make much sense in a container, so the best thing to do is to disable udev and create needed device nodes manually.

You might need then to check it with your hosting company.
