Uh, you've got it backwards dude - inetd was developed way way back in the day, when having a separate telnetd, ftpd, etc all running all the time consumed too many resources. Most modern daemons (sshd, apache, bind, dhcpd, etc) all run as standalones - the ones that still want inetd are stuff like talkd, fingerd, uucpd - ie, the daemons that no one runs anymore. And how is having two daemons (inetd and sshd), each with their own config files and implementation bogosities _simpler_ that just the one? Uh, I could run inetd _and_ sshd, or just sshd - hmm, which do I think is simpler...? And sshd has all the "advantages of inetd" which you mention. - From a security standpoint, I really think that inetd outght not be used. It's an additional root-running source of complexity and potential bugs, and it is almost never necesary. -Jason -------------------------------------------------------------------------- Freud himself was a bit of a cold fish, and one cannot avoid the suspicion that he was insufficiently fondled when he was an infant. -- Ashley Montagu -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.1 (FreeBSD) Comment: See https://private.idealab.com/public/jason/jason.gpg iD8DBQE/alzsswXMWWtptckRAn7BAJ9L+V4XAgaJCe3cIm40k34RXdkRXQCg1RXm u20B+ZxFFSMyNH2OAnuK3X4= =9Dxo -----END PGP SIGNATURE-----
