I hope you've already checked this - do you have a firewall enabled on either host blocking the packets? in the output of '/sbin/iptables -nL', you should see something like this: Chain INPUT (policy ACCEPT) target prot opt source destination ... <excerpted> ACCEPT udp -- 0.0.0.0/0 0.0.0.0/0 state NEW udp dpt:8649 If you don't have a rule accepting ganglia data (or your firewall is completely open), the traffic will be blocked. -ben -- Ben Hartshorne email: [EMAIL PROTECTED] http://ben.hartshorne.net
