To verify the actual current ports open on any node, use the iptables --list -n -v
command.
12.2 Opening Ports in the Firewall
CAUTION: Opening an IP port can constitute a breach of security. Use the following information
with care.
You can open a port in the firewall on any node by using the openipport command; however,
that port opening specification is overwritten when the node is reimaged. The exception is the
head node, which as the golden client, is not reimaged. This command is described in “Opening
a Temporary Port in the Firewall” (page 155).
Alternatively, you can open an IP port in the firewall globally on all the nodes by updating a
single file; the port remains open after the nodes are reimaged. For more information, see
“Opening an IP Port in the Firewall Persistently” (page 155).
