Hi,
I am trying to cut down the NNTP traffic we receive. We use dnews as
our news server, receiving a live feed from our upstream (who are
running Cyclone). I would welcome suggestions as to how to do this.
Previously, we have received 25-32G of NNTP traffic per day. I set
cachedonly to true in /etc/dnews.conf, and traffic seems to have dropped
to 20-23G per day over the last two days. "tellnews showcached" shows
that we have 89 groups being read by our clients. dnews.in shows that
we are rejecting a lot of newsgroups. I would have expected a far
greater drop in received traffic than this.
Perhaps the rejected articles are being sent to us in full and then
rejected?
As far as I know, Cyclone does not support newsreader commands, so
header caching is not an option. The command set reported by the help
command on Cyclone is: authinfo, check, date, filter, help, ihave, list,
mode, takethis, quit. Supported modes are filter and stream.
The relevant section of newsfeeds.conf is:
site news1.optus.net.au
groups
*,!sa.*,!ua.*,!unisa.*,!adel.*,!syd.*,!csiro.*,!alt.test,\
!dsto.*,!alt.binaries.*
exclude news1.optus.net.au
type live
maxcross 4
dnews.conf contains:
