Hi Filip, I have figured out (for the most part) what is happening:
Using Ethereal, I determined that even though I was setting the mcast bind address to the private adapter, traffic was still being broadcasted on my public adapter. After some investigation into the Tomcat source code, I determined that the server.xml cluster comments don't reflect what the code is expecting for the bind address parameter name. The server.xml comments say to use "mcastBindAddr" whereas the source code is actually looking for "mcastBindAddress". After the mcastBindAddress fix, UDP broadcasts were sent/received by both nodes correctly. I suppose the public adapter configuration on nodeB was set in some way to ignore UDP traffic. I appreciate your assistance. Thank You. -----Original Message----- From: Filip Hanik - Dev Lists [mailto:[EMAIL PROTECTED] Sent: Monday, March 27, 2006 11:02 AM To: Tomcat Users List Subject: Re: Cluster member discovery please attach both your server.xml files, I'll take a look at them.
