Just ran into a problem where some mutlicast tests were failing on a linux box and I could not figure out why. Did a little bit of research and found out that you may need to add a route for it first. So if you have this problem try running:

route add 224.0.0.0 netmask 240.0.0.0 dev eth0

or if you have an older version of linux like me:

route add -net 224.0.0.0 netmask 240.0.0.0 dev eth0

Nice to see the new year starting off right. I Noticed this post over at the eaimatrix.com:

A plethora of message queuing products exist in today’s EAI market, all aimed at providing solutions to the problem of application integration. Few can however lay as much claim to fame as ActiveMQ, an open source Message Broker and JMS/Enterprise Integration Patterns provider which is licensed, developed and distributed under the open source Apache emblem. ActiveMQ provides support for Cross Language Client and Protocols as well as a powerful messaging broker which is supported in Java, C, C++, C#, Ruby, Perl, Python, PHP.

Wow, it’s been a while since I’ve posted but several exiting events have been happing in the ActiveMQ arena.

• Apache ActiveMQ has GRADUATED out of the incubator and is an official Apache project!
• The ActiveMQ website has moved to http://activemq.apache.org and has received a new face lift thanks to yours truly.
• ActiveMQ 5.0 development is making huge progress and Rob has put up an excellent post outlining the upcoming features in the next version of ActiveMQ.

If you want to get a preview of those features, get the latest from the ActiveMQ trunk and kick it around. Feedback would be appreciated.
