Hello, Setup: Two-node RHEL 4-based fail-over cluster. The nodes are multi-homed, i.e. they listen to several network interfaces for various purposes. Dedicated heartbeat ethernet (cross-over) cabling is used for cluster heartbeat. I don't like the fact that the cluster-related daemons listen on multiple network interfaces. One should be sufficient. However, it seems that the daemons (like ccsd) don't have a parameter to specify which interface to listen/communicate on. So I thought that I would use iptables to limit network access to the daemons. In the manual page for ccsd, the "-P" argument is described. The argument governs which ports are being used for inter-ccsd communication ("b"), cluster membership communication ("c"), and administrative programs ("f"). But how are multiple values specified? Like this?: -P b:xxx c:yyy f:zzz or like this?: -P "b:xxx c:yyy f:zzz" or like this?: -P b:xxx -P c:yyy -P f:zzz -- Greetings from Troels Arvin -- Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
