The output of few files in /usr/bin/ is as follows:

What could be the problem and how do i resolve it??
Chmod doesn't seem to work! Using root It still doesn't give me permissions to edit it's permissions! Could it be a filesystem problem. The inode problem...? How do i rectify this??

Please helppp!
Savio.

suggest thus:
cd /usr
ls -l bin
check permissions on bin: try chmod a+x bin
cd /
ls -l usr
check permissions on usr: try chmod a+x usr
if that doesn't fix it, please post yr /etc/fstab
