- Glad to hear that. I may go through the exercise, even though
- nobody uses my 3B1s from the console these days.

- I think that his primary problem is inadequate news spool disk space
- on the "One machine". Given that, and since he can't reduce the space used
- by the news spool (/usr/spool/uucp or /var/spool/uucp may be on a
- different partition), it may make since to use it to forward certain
- newsgroups to a second machine quickly, and then expire the news on the
- first. However, C-news comes with 'viarsh' scripts which are quite adequate
- for exchanging news between a Sun and a 3B1, as I've proven during my
- transition phase. The primary thing is that the scripts on the 3b1 need to
- replace 'rsh' with remsh' in the interests of getting off the local machine,
- instead of getting locked into a *restricted* shell. (Aren't flavor
- differences fun. :-)
-
- It may also be lack of experience with the TCP/IP utilities, and
- lots of experience with uucp that is motivating his choices. In any case,
- they are *his* choices, and we can only offer advice.
-
- Yes, I agree that he has fewer critical points of failure with
- everything spooled on a single machine, and accessed via nntp (as I do), but
- it may have been cheaper to get the ethernet card for the 3B1 than to get
- enough disk for the primary machine. (I don't remember what that machine
- was, or even whether it was spelled out. If it is another 3B1, and neither
- of them are modified to allow two disks, and bigger disks, then he is
- probably stuck.) Even with a Priam as one of the two disks on my 7300, I
- had spool overflow problems from time to time, usually when the maps came
- flooding in. (Of course, a large chunk of space was tied up with my sources
- tree, and another part with the archiving of groups of interest between
- shuffling them of to tape.

- Good Luck All
