Having recently aliased the old "unix-pc.general" newsgroup to the new "comp.sys.3b1" group, I discovered a little problem which must have existed for some time. If someone crossposts an article to both of these groups, then C news generates two copies of the article in "comp.sys.3b1". Both copies have the same message ID and in fact, the files are identical in the spool directory. Is there a clean and simple way to eliminate the duplication of these articles? Thanks for any help you can offer. -- Jeff Small C. Jeffery Small & Associates (206) 232-3338 uunet!nwnexus!cjsa!jeff 7000 E Mercer Way, Mercer Island, WA 98040

Nothing off-the-shelf. A newsreader that respects the Xref header line will only show you one of them anyway. It's a peculiar quirk, but relatively awkward to fix, and it didn't seem worthwhile. It's not eating up any extra disk space (except to the small extent that directory entries consume disk space). -- If the Space Shuttle was the answer, | Henry Spencer at U of Toronto Zoology what was the question? | henry@zoo.toronto.edu utzoo!henry

I'm running rn at patch level 47, (on a AT&T 3b1, Sys V) and it does seem to be properly handling normal cross-posted articles, (i.e., an article cross-posted in misc.forsale and misc.forsale.computers, when read in misc.forsale, was not shown to me in misc.forsale.computers), but it is definitely showing both copies of articles cross-posted in unix-pc.general and comp.sys.3b1. Can anyone validate Henry's statement, or do I have a configuration problem in my version of rn? How about anyone with other newsreaders? >If the Space Shuttle was the answer, | Henry Spencer at U of Toronto Zoology -- Dave Hanna, Infotouch Systems, Inc. | "Do or do not -- There is no try" P.O.

Use the 'v' command in rn to look at the headers. If there's no Xref: line, something's wrong. Also double-check the Newsgroups: line -- some broken news posting software has been known to generate separate copies of the posted article to each newsgroup. >Can anyone validate Henry's statement, or do I have a configuration >problem in my version of rn? There are/were some patches dealing with Xref's (I think the patches were to C news). -- Bruce Lilly blilly!balilly!bruce@sonyd1.Broadcast.Sony.COM
