[gentoo-user] problems with udev

[renna]

hi to all
i'm having some problems, with, i think, the permissions 
of /dev/null /dev/console and /dev/zero. every time i boot they're set up to 
660, like this

crw-rw----  1 renna root 5, 1 Jul 13 17:04 /dev/console
crw-rw----  1 root  root 1, 3 Apr  9 06:31 /dev/null
crw-rw----  1 root  root 1, 5 Apr  9 06:31 /dev/zero

so when i login as a normal user, i get
/dev/null: Permission denied

and i have to
chmod 666 /dev/null

to be able to login in kde

furthermore, in kde, when i launch konsole, the window of konsole shows up, 
but there's only the cursor blinking, and i cannot enter commands - i have to 
ctrl+alt+fn to a terminal
and allways in kde, when i launch a program that requires root's password, as 
kuser, i get a window with this message

The program 'su' is not found;
make sure your PATH is set correctly.

though su, which is perfectly working in a terminal, is in /bin which IS in my 
PATH

i really don't know if these problems in kde are correlated with the 
permissions in dev, but on google i found many persons having problems with 
udev and having more or less the same problems (though i couldn't find a 
solution to my case). i tried, as explained on 
http://www.gentoo.org/doc/en/udev-guide.xml#doc_chap3
to mknod new null and console in /dev, but when i boot the permissions are 
again set to 660. 
does somebody have an idea of what i should do? if there's some information i 
lacked to give please ask
thanks

I switched last night from devfs to udev and had the same kde problem.
I solved it by running udevstart as root. Oh, and I checked the permissions 
file in /etc/udev

Now I have the problem thatthe module for  my scsi-controller is loaded 
everytime (loosing a lot of time at boot) and the soundcards are detected in 
the wrong order ...

If running 'udevstart' fixes your ownership/permissions problem, try logging
in again and see if the problem reappears. If it does, then it means something
is running on login and imposing its own permissions. This is probably pam,
which you'll want to turn off.

Try checking a file called /etc/udev/permissions.d/50-udev.permissions, this 
file sets the permissions of devices during boot.  My line in that file is:

null:root:root:0666

which sets the permissions to 0666 which is what you expect.

I had problems with some other devices, like misc/nvram, and had to make 
modifications to the file.

No. This has already changed since more than 10 versions of udev. 
Permissions are now set in /etc/udev/rules.d/50-udev.rules.

Bye...

This file will be changed when you update. Your own settings should go
in /etc/udev/rules.d/10-udev.rules.
