There are a number of cases where the sudo paradigism is ummm silly, but *they* dreamed it up and *they* will defend the concept to the death. sudo sh passwd login as root If external logins as root are your worry: /etc/ssh/sshd_config PermitRootLogin without-password or even no If internal logins are your worry use public key and a pass phrase and a very non trivial password say 10-15 chars. There has been discussion and money offered, but not claimed, to break non trivial password. Don't worry about CAPS NUMS etc length is wot counts. [ logic for sudo seems to be: bad guys want to get your system: using root is guaranteed as as name leaving passwd to be cracked, vs guessing a name and a passwd] James ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
