2.2.3. Examples of iptables Rules

This section provides iptables rule examples for enabling IP ports on Red Hat Cluster nodes and computers that run luci. The examples enable IP ports for a computer having an IP address of 10.10.10.200, using a subnet mask of 10.10.10.0/24.

Note

Examples are for cluster nodes unless otherwise noted in the example titles.

Example 2.1. Port 6809: cman

-A INPUT -i 10.10.10.200 -m state --state NEW -p udp -s 10.10.10.0/24 -d 10.10.10.0/24 --dport 6809 -j ACCEPT

Example 2.2. Port 8084: luci (Cluster Node or Computer Running luci)

-A INPUT -i 10.10.10.200 -m state --state NEW -m multiport -p tcp -s 10.10.10.0/24 -d 10.10.10.0/24 --dports 8084 -j ACCEPT

Example 2.3. Port 11111: ricci (Cluster Node and Computer Running luci)

-A INPUT -i 10.10.10.200 -m state --state NEW -m multiport -p tcp -s 10.10.10.0/24 -d 10.10.10.0/24 --dports 11111 -j ACCEPT

Example 2.4. Port 14567: gnbd

-A INPUT -i 10.10.10.200 -m state --state NEW -m multiport -p tcp -s 10.10.10.0/24 -d 10.10.10.0/24 --dports 14567 -j ACCEPT

Example 2.5. Port 16851: modclusterd

-A INPUT -i 10.10.10.200 -m state --state NEW -m multiport -p tcp -s 10.10.10.0/24 -d 10.10.10.0/24 --dports 16851 -j ACCEPT

Example 2.6. Port 21064: dlm

-A INPUT -i 10.10.10.200 -m state --state NEW -m multiport -p tcp -s 10.10.10.0/24 -d 10.10.10.0/24 --dports 21064 -j ACCEPT

Example 2.7. Ports 40040, 40042, 41040: lock_gulmd

-A INPUT -i 10.10.10.200 -m state --state NEW -m multiport -p tcp -s 10.10.10.0/24 -d 10.10.10.0/24 --dports 40040,40042,41040 -j ACCEPT

Example 2.8. Ports 41966, 41967, 41968, 41969: rgmanager

-A INPUT -i 10.10.10.200 -m state --state NEW -m multiport -p tcp -s 10.10.10.0/24 -d 10.10.10.0/24 --dports 41966,41967,41968,41969 -j ACCEPT

Example 2.9. Ports 50006, 50008, 50009: ccsd (TCP)

-A INPUT -i 10.10.10.200 -m state --state NEW -m multiport -p tcp -s 10.10.10.0/24 -d 10.10.10.0/24 --dports 50006,50008,50009 -j ACCEPT

Example 2.10. Port 50007: ccsd (UDP)

-A INPUT -i 10.10.10.200 -m state --state NEW -m multiport -p udp -s 10.10.10.0/24 -d 10.10.10.0/24 --dports 50007 -j ACCEPT
