Hello,

I am a telecommunication enginnering student and I'm working on my final
degree thesis using Apache River technology. My goal is to integrate the
distributed capabilities that River offers with a previously developed
software written in the Java programming language.

I've been working for some months using reggie as the Lookup Server. I've
always tried my programs using a single machine. I've been careful in the
sense that I've executed client, server and reggie in different locations,
different JVM's, etc. However, problems arise when we try the software
developed so far in 3 different machines: we are unable to get a response
from reggie. We are executing reggie with the default configuration provided
with the "hello" example.

As everything works fine in a single machine with the proper cautions to
simulate a distributed system, we suspect that the problem is related to
network configuration, firewalls and switches. We perform multicast
discovery in order to contact reggie (yes, unicast discovery may work, but
the software we are developing would be pointless if we needed a specific
server URL).

May there be some problems with multicast packets? Could someone post a list
of possible reasons that could make the visibility of reggie crash if it
works fine in a single machine?

Next days we'll perform some more testing and hopefully I'll be able to
provide you with more data.

Thanks in advance,
