Help...Can only log in as root after this command

ScreeminChikin · 11-11-2002, 10:22 PM

I have been trying to get XMMS to work and after doing the following command, I can only log in as root. Even if I go in and create a new user I cant log in as that user. What did I do wrong and how can I undo it? This is RH7.3 and the command was as follows ....

chmod 622 /dev/dsp and chmod 666 /dev/mixer

When I try to log in as any user, the screen just linda blinks a couple of times, I can see the little X in the middle of the screen and it kicks me right back to the login screen.

As a follow up.....I did a ctl-alt-F2 and tried to log in as my regular user and I get this

/dev/null
permission denied

Don't really know what it means but I figure it could have something to do with it and I dont get that when I do the same as root.

Try running chmod 666 /dev/dsp and see if it will let you log in as user.

I get the same thing. What exactly does chmod do?

try man chmod
then touch /root/nullpermissions
then ls -la /dev/null > /root/nullpermissions --Now you made a file with original permissions of /dev/null, just in case this doesn't work and you have to put permissions on /dev/null how they were.
now
chmod a+rwx /dev/null
then try to login as another user, it looks like permissions for /dev/null were messed up, if it doesn't work then refer to /root/nullpermissions file you made to restore the permissions as they were.
Also try to login as root and su to any user, for example if youre user is called foo you would login as root and do
su foo
and see is it will switch to user foo.
Hope that helps

Ok....I read through the manpage on chmod. It may as well have been written in vulcan for all I understood of it. I tried those commands and it didnt seem to make any difference. What exactly is null? Is there a configuration file somewhere that I can somehow restore from the disc or whatever that will put all the permissions back to how it was out of the box? Its no big deal to go in and redo my user accounts if I could do that somehow. Thanks for the help, I cant believe I screwed the thing up so bad trying to listen to music.
