[infinispan-dev] Infinispan EC2 demo firewall issue without locked down FD_SOCK start_port

Hi Noel, First of all, thanks a million for writing http://infinispan.blogspot.com/2010/05/infinispan-ec2-demo.html. I think the work you did there is excellent. I had a question for you though. In your jgroups-* files, you use FD_SOCK without a start_port which by default binds to random port (http://community.jboss.org/wiki/JGroupsFDSOCK). Given Amazon rules, I don't think clustering is working as expected in your case, cos without locking this port and opening it in the firewall, you'll see WARN messages like this in the logs and the cluster view will not form: 2010-06-13 16:50:54,478 WARN [org.jgroups.protocols.FD_SOCK] (OOB-1,infinispan-cluster,ip-10-194-230-242-27003) I (ip-10-194-230-242-27003) was suspected by domU-12-31-38-00-9C-52-25127; ignoring the SUSPECT message To get around the issue do the following: - Lock your FD_SOCK start_port values, i.e. <FD_SOCK start_port="9777"/> - Open TCP port 9777 in your security group. I'd suggest you verify your demo expectations bearing in mind this information and once you've done so, update the blog post :) Cheers, -- Galder Zamarreño Sr. Software Engineer Infinispan, JBoss Cache
