Re: Problem with multiple sites and crossposting

: B.  Computer A connects to B at regular intervals and reads the groups
: hosted on B, and vice versa.

: Now, recently it happened that someone cross-posted to three groups:
: two of the groups were hosted on A and one of them on B.  What happens
: is that SN gets somehow out of sync and the message for the newsgroup
: on B now reappears every few hours as a new post.  Over the weekend,
: we managed to accumulate the same post tens of times =)

How are you retrieving the articles?
Does this indeed save bandwidth?

Since both sites have the same admin, in your position I would
sync both by having each log in to the other, and issuing sncat -n,
and feeding that output for snstore; instead of relying on nntp.
Since bandwidth is an issue, this can be compressed at the source
and decompressed at the target host.

sn wasn't designed to host other sites, so it does not do one
critical thing: check for loops.  It's not too hard to do this from
a shell script, basically just make sure any message about to be
stored does not have self's hostname in the Path: line.
