UUCP = Unix-to-Unix CoPy. It is an old but still used way of sending files and execute command across serial lines (and TCP as well). It predates TCP/IP and is used mostly now by European and people who pay by the minutes (or bytes) their phone lines. It is the most efficient way of transfering news batches I know on serial lines. We have a good network of UUCP connected machines here in France and I manage a small USP (Usenet Service Provider :-)) along with friends. We have around 40 people that would kill anyone wanting to remove UUCP support :-) We even have people with PPP or cable connections that are still using UUCP (over TCP) in order to get their mail/news. You don't need hacks like POP before SMTP or multiple mailbox support in POP/IMAP with UUCP. Routing entire domains is natural and multiple account is native usage. -- Ollivier ROBERT -=- FreeBSD: The Power to Serve! -=- roberto@keltia.freenix.fr FreeBSD keltia.freenix.fr 4.0-CURRENT #74: Thu Sep 9 00:20:51 CEST 1999 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-security" in the body of the message
