That assumes that su's permissions have not been altered; and give the command line executed .... Looks like you will need to boot from unaltered media (CD/DVD/USB) or remove the drive and mount it on another system, and use that system to reset the file ownership. -----Original Message----- From: sudo-users [mailto:[email protected]] On Behalf Of Todd C.

On most other systems you should be able to use "su" to change to the root account. To repair the ownership and mode run: chown root /usr/bin/sudo chmod u+s /usr/bin/sudo - todd ____________________________________________________________ sudo-users mailing list <[email protected]> For list information, options, or to unsubscribe, visit: https://www.sudo.ws/mailman/listinfo/sudo-users ____________________________________________________________ sudo-users mailing list <[email protected]> For list information, options, or to unsubscribe, visit: https://www.sudo.ws/mailman/listinfo/sudo-users
