The problem is that NNTP provides no easy way to ask for a crucial piece of information: "which of the articles in the min..max range actually exist?". Keeping min up to date, with upact or updatemin, helps. (It does not actually solve the problem, since the min..max range is not necessarily densely populated, but it helps. The only real fix is to fix the NNTP protocol.) >Also, the sever might want to run a "find /usr/spool/news >-mtime +30 -exec rm {} \;" now and then. Shouldn't be necessary under C News, unless your system crashes a lot. C News doesn't lose articles, unless the underlying system fails on it. Also, again under C News, a better way to do this is to run the (new) "addmissing" program occasionally. That adds any orphaned articles to the history database, so they can expire normally, without disturbing articles that legitimately have an expiry time longer than 30 days. It's also typically faster. -- If the Space Shuttle was the answer, | Henry Spencer at U of Toronto Zoology what was the question? | henry@zoo.toronto.edu utzoo!henry
