i could never imagine that it is possible to call a command and then have root rights for it, without authentificating on the system with a password. so i thought a daemon running as root might solve that problem (which i thought it does exist) ;-). but since today i can not imagine how sudo is doing that - it might be very difficult to explain since i couldn't find an explantion on the net. so, how is sudo doing this auth-job, even with no password-verification. how does sudo treat the system? has anyone an answer to that so i can understand it?

So IOW sudo always runs as root, the whole authentication thing is only to determine whether sudo should run something else. -- Andrew Donnellan ajdlinuxATgmailDOTcom (primary) ajdlinuxATexemailDOTcomDOTau (secure) http://andrewdonnellan.com http://ajdlinux.wordpress.com [EMAIL PROTECTED] hkp://subkeys.pgp.net 0x5D4C0C58 http://linux.org.au http://debian.org Get free rewards - http://ezyrewards.com/?id=23484 Spammers only === [EMAIL PROTECTED] === -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
