Problems using SU.

Hi. I have been having troubles. For some reason when i run su from Xterm in kde it asks for root password but it will not accept it. I had no problems with that before. I cant figure out whats wrong, even when i try to do something like use sudo to get root access to an application it wont accept root password. I know that the root password im using is correct because i can login locally through command but i cant login to kde as root because obviously it wont let me. Also my user is in the wheel group so no problems there.

Does anyone know why it might be doing this?

Thanks in advance,
Regards Ben.

check permission. It should have set user id or group ID on execution (s).

OK. I read your post and i checked the permissions for /bin/ which is where su is located and every file in /bin/ is owned by 1000:441. Is this normal?

Thanks again

Hi Ben,

I think there should be root:root for all files when you do a ls -l of /bin.
What happens when you do a chown root:root /bin/su and retry?

You can just simply use -R option, such as

chown -R root:root /usr/bin

And you right about /var. Some has to be own by apache, mysql ... So it is important to check owner of the /var before you do chown command. If you don't have to, don't do it. However, if it is already be 1000:441, you have no choice but to change them to root:root, and then you have to find out which directories/files need to be owned by other user beside root. You better have the second working gentoo around, so that you can compare.

does the "-R" option meen that it will change every file in the directory ?

Thats a good point i can check it against my gentoo server

-R means recursive to subdirectory. So every fiiles and every subdirectories will be changed. Grad to hear that you have another machine to compare with. Have fun.
