Hi,
When I start my gentoo system up I can't log in as a user. Kde hangs
on initialising peripherals. I found that by doing a console login as
root and changing permissions of /dev/null from crw-rw---- to 666 I could
then login. However I couldn't open a terminal etc as it never responded.
No devices worked (Sound etc). Now if during that login I chmod -R 777
/dev everything works as normal. What should the permissions be on /dev
and how do I set it so that they are by default?

Thanks

Any error messages?

# ls -l /dev/null
crw-rw-rw- 1 root root 1, 3 Sep 27 14:35 /dev/null

Do you know of any reason why your /dev/null might revert to crw-rw----?

# ls -l / | grep 'dev'
drwxr-xr-x 16 root root 3520 Sep 27 13:36 dev


Is this a new installation? Has your system ever been working correctly?
What changed?

Nope, just hangs, nothing in /var/log/everything/current I have to kill X
to get control back

Fine, that is what my other gentoo laptop is as well

Absolutely no idea that's why I'm asking. I'm wondering if something was
updated during an emerge -u world

It is a relatively new install but was working fine until a couple of
weeks ago. Unfortunately the lappy had to go back as it developed a screen
fault so I'm not sure of an exact date it started doing it. It gets reset
everytime I restart the laptop. What process sets up the /dev hierarchy on
bootup?

Oh, an X login as user. If not explicitly stated, a console login is
assumed (we are on *nix, you know).

Do you have udev? If so, check you have the following line in
/etc/udev/rules.d/50-udev.rules :
> KERNEL=="null", NAME="%k", MODE="0666"

Also, check /etc/udev/permissions.d/50-udev.permissions for:
> null:root:root:0666

Hth,

This exists but I noticed that a lot of stuff is set to 0600, Am I right
in thinking that I can change these to 0666?

No, some things do need to be 0600.

Since udev is creating /dev/null with mode="0666" there must be
something else changing the mode afterwards. What it is I'm not sure -
all out of ideas here.
