Not able to login as root

[logaraman]

hi ,

We are unable to su - root from a mormal user. It gives the error saying sorry and also when i tried to check the diskspace, i get the following error
"df: Cannot open /etc/mnttab: Permission denied"

Anything serious on this

I would be worried about the message denying permission to /etc/mnttab.

Can you cd to /etc? If so, what do you see when you type ll mnttab?

Hello,

Check permission on /etc/mnttab. Are you able to cat /etc/mnttab ? It should be 644..

Also, check this thread

check the permission of /etc/mnttab. It has to be like,

-rw-r--r-- (644) root root

permission.

Hi Log,

The df error message has nothing to do with the issue that u are not able to su to root (su - root).

It simply means ,as a normal user u are not able to perform df.

As far as su - root is concerned, doest it atleast prompt for a password? or just the message sorry.

what is the error you got when trying to login as su - root? IT is good to have to analyse that problem. Changing the permission will make to resolve Permission denied error.

Oops,

sorry ..I did not check the permission of /etc/lvmtab. well if it is 644, you should also be able to perform df as a normal user.

well do check the permissions on the file, also let us know, whether it just says sorry without prompting password, when issued su - root.

regards,
Senthil

Hi,
