I found a system where a root cannt change or modify any file oradministration tasks( no permission of root) even though root hasroot permission in /etc/passwd fileie "root:x:0:0:root:/root:/bin/bash".Whts the trick behind this? can anybody tell me how to do this.
Using CHOWN... you can transfer the ownership of practially all files toanother user. Then make a group for that user at 0, and move rootsomewhere else. Dont try it on a production system, as it's bound tomake a few problems.
