Please help: "df -k" reports permission problem

[ha haha]

Hi,

 Anyone see the odd problem? "df -k" reports
"Permission denied" error to normal users, while it is
OK for root.

 I know it maybe related to somewhat security
settings, But I don't like, I'd like to turn off it
since it will make every normal user annoyed in few
hours. 

 Any one know how to turn off it?

Thanks a lot.
