Hi,

In my system there's a strange behaviour.... its not allowing me to create any file in /usr/bin even as root. Its chmod is set to 755. Its even not allowing me to change the chmod value of /usr/bin. The strangest part which i felt is ...its shows the owner and group as root when i issue command "ls -ld /usr/bin" and not allowing root to create any file or directory under /usr/bin and not even allowing to change the chmod value. The error is access permission denied... I can change the chmod value of /usr and other directories under /usr/...but not of bin....

I need your help/support. kindly let me know what all can i try to resolve this problem.

Thanks and Regards,

See if your file-system has gotten hurt. Boot with init=/bin/bash and execute `/sbin/fsck -f /` to force a check of the root file-system.

The next check is to see if you can fix the protections when
you are the only one accessing the file-system:

# mount -n -o remount / # re-mount root r/w
# cd /usr
# chmod 755 bin
# ls -la # See if it worked
# unmount /

The next check is to replace the /usr/bin directory. Since `mv`
and `mkdir` are in /bin, the following should work.

# mount -n -o remount /  # re-mount root r/w
# cd /usr
# mv bin foo # Rename 'strange' directory
# mkdir bin # Make a new one
# cd foo # Change to original
# mv * ../bin # Rename all contents to new
# cd .. # rmdir foo # Remove bad directory
# chmod 755 bin # Fix protection
# umount /

After you have fixed things, you don't have to re-boot.
Just execute:

# exec /sbin/init auto
