[KLUG Members] logging internet connection attempts

[Eric Beversluis]

Good sites, but they don't address our issue. Here's where the mystery
lies: We're setting up a Domino server on a Linux box. At a certain
point we have to run Remote Server Setup on a separate box which then
sets up the server as a secondary server to the "mother server." It's
when the communication has to happen between the primary server and the
secondary server that the network fails. We don't know whether the
Remote Server Setup prompts the new secondary server to communicate with
the primary server, or whether RSS tells the primary server to now
communicate with the new secondary server. In any case the communication
between the two Domino servers breaks down. And since it doesn't break
down when we're using all private IP addresses over a VPN tunnel, we
conclude that it's a firewall/port issue. All we know is that the
communication is not trying to happen on the normal Domino port, since
that communication works fine once the server setup does succeed, and
that port is open on both computers when the communication fails.

Thanks anyway.
