Hi: Can someone give me an illustration what the advantages of uucp over tcp/ip are? I come across all these commands like cu, uux, etc. But why bother having them around if ftp and telnet are so much easier to use with a single internet address? Also, when I try using nslookup to search for some internet addresses the server simply reports that there is no such domain. Most of these problematic addresses are those with suffix like uunet and uu.com. What is the problem? Thanks for answering my questions Szeto.

The advantages of uucp over tcp/ip go something like this: 1) UUCP queues jobs. If you want to copy a file (via 'rcp') and the network happens to be down, you must try later. If you want to run a remote execution (via rsh/remsh) and the network is down, you must try again later. UUCP queues the job and keeps trying until either the job is complete or a time limit (several days) expires. We actually run UUCP over TCP/IP for remote executions and E-mail. (Yeah, I know, I don't need uucp for mail, but it works well for us and I hate to fix something that isn't broken.) 2) UUCP is *CHEAP* to run. Just about any machine comes with at leastl one extra RS-232 port. If I need to get to a machine in Intercourse, PA and that machine does not have Internet access, it's a lot easier (and cheaper) to get uucp set up than to get TCP/IP set up. This may comes as a shock to many people, but not all UNIX machines have Internet access. Many machines at AT&T only have UUCP access to the handful of machines with Internet access. I hope this helps... ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Rich Brown {att!}vogon!rsb AT&T Network Systems OR Lisle, IL rsb@vogon.att.com
