df -k error

[logaraman]

Hi,

wehn i execute df -k command on a HP server as a normal user, i get the below error " df: Cannot open /etc/mnttab: Permission denied"

Suggestions pls

See the permissions of /etc/mnttab it should have read permission for group and other i.e. -rw-r--r-- and your df command (/usr/bin/df) should have a setuid bit i.e. -r-sr-xr-x

Cheers

Hi,

As a non root user you will get the following when the permissions on /etc/mnttab aren't correct

$ sudo chmod 640 mnttab
$ bdf
bdf: Cannot open /etc/mnttab: Permission denied
not correct:
-rw-r----- 1 root root 1460 Jun 22 11:24 /etc/mnttab
Correct:
-rw-r--r-- 1 root root 1460 Jun 22 11:24 /etc/mnttab

-r-xr-xr-x 1 root bin 73728 Jul 18 2001 /usr/bin/df
