Hi Daryl,
A couple of quick comments:
- Mike found that a site in Brazil was trying to connect to iddb
every 5 seconds, and this was causing a myriad of problems
The site's IP address (there is no reverse DNS for their IP), has
been blocked, and things have quieted down a bit.
Time will tell if this was a cause/the root cause of the latency
problems on connections to iddb. It does not, of course, have
anything to do with high latencies on idd.
- several years ago (3, 4, more? I can't remember) we had a problem
with connections from a downstream piling up when old connections
were not seen by the upstream machine to be gone
I remember that the problem was eventually traced back to a firewall
setting on the upstream machine, but exactly what needed to be tweaked
is not coming to mind right now. I will be "talking" to Mike to see
if he remembers exactly what we needed to do.
Also, this situation was what led to the implementation of DOS capability
in the LDM
Again, just a couple of quick FYIs...
Cheers,
Tom
