cman & iptables

In case cman crashes with cpg_send_message failed: 9 add those to your rule set:

iptables -A INPUT -m addrtype --dst-type MULTICAST -j ACCEPTiptables -A INPUT -p udp -m state --state NEW -m multiport –dports 5404,5405 -j ACCEPT

The second rule is not correct at least on the default debian squeez from iso.

-dports needs 2 dashes. Below are the corrected rules.

iptables -A INPUT -m addrtype --dst-type MULTICAST -j ACCEPT
iptables -A INPUT -p udp -m state --state NEW -m multiport --dports 5404,5405 -j ACCEPT
