Aidan,

  Thanks for the reply. I've been pulling my hair out on this. I wonder if it
could be the Sharp Copier (older M355N) I have attached to the network. It has
a separate fax module (and also supports network delivery of faxes) and it
also a network scan-to-pdf via a ftp link to a samba share on the server
(that's all on port 22, so it shouldn't matter). I wonder if it has a 20 sec
ping or something that is checking to make sure the a network link is up and
is somehow triggering the logging? I'll have to find the manual and see if any
of its communications are over the same port. Oh that would be frustrating if
a dang copier was pinging the hylafax port.

  Right now, the copier is asleep and I'm not getting any of the annoying
logs. So I guess the plan going forward is to increase ServerTracing for hfaxd
to try and identify who the culprit is. I think I have an understanding of
what to do. When I up ServerTracing to 0x33, will it provide information I can
identify the culprit with?, or will it be some cryptic bitfield I have to find
a reference for?
