You can try replacing the chmod and chown binaries with your own "hacked" version which prevents a user from modifying the permissions of their respective home directory. But then any user who knows C and has access to a compiler can use the system call. Better still... you should add the users such that their home directory is owned by root and the group ownership is their own. for eg. I have two users test1 and test2 [EMAIL PROTECTED] /home] ll drwxrwx--- 3 root test1 4096 Aug 4 23:12 test1 drwxrwx--- 3 root test2 4096 Aug 4 23:13 test2 Try it out.
