If you are deploying
the SAS LASR Analytic Server, then you must define one port per server
in /etc/sysconfig/iptables. (The port
number is defined in the SAS code that starts the SAS LASR Analytic
server.)
If you have more than
one server running simultaneously, you need all these ports defined
in the form of a range.
Here is an example of
an iptables entry for a single server (one port):
-A INPUT -m state --state NEW -m tcp -p tcp --dport 10010 -j ACCEPT
Here is an example of
an iptables entry for five servers (port range):
-A INPUT -m state --state NEW -m tcp -p tcp --dport 10010:10014 -j ACCEPT
MPICH_PORT_RANGE must
also be opened in IPTables by editing the /etc/sysconfig/iptables file
and adding the port range.
Here is an example for
five servers:
-A INPUT -m state --state NEW -m tcp -p tcp --dport 10010:10029 -j ACCEPT
Edit /etc/sysconfig/iptables and
then copy this file across the machine cluster or data appliance.
Lastly, restart the IPTables service.
