Shutting Down iptables

WARNING! Inform your network administrator before you stop a running firewall, even

momentarily. Disabling the firewall creates a potential security breach, and you must weigh this

threat against the benefits of live troubleshooting.

1. Enter /etc/init.d/iptables status and press Enter to see if the firewall software is

installed and running.

— If you see the message No such file or directory, then standard firewall software

is not installed and you can proceed to “First Troubleshooting Steps” (page 22).

— If you see the message Firewall is stopped, proceed to“First Troubleshooting

Steps” (page 22).

— If you see output indicating the firewall is running, proceed to the next step.

2. If the firewall is running, enter /etc/init.d/iptables stop, and then press Enter to

stop the firewall. You can then proceed to “First Troubleshooting Steps” (page 22).

First Troubleshooting Steps

Most errors are due to mismatched community strings entered during agent configuration on

the managed server. Follow these steps , which include confirming the community string settings,

before performing more advanced troubleshooting:

1. Examine the SNMP daemon configuration file. If your system is running RHEL, this file is

located in /etc/snmp/snmpd.conf. If your system is running SLES, this file is located in

/etc/snmpd.conf. The first set of directives should be delimited by the following comment

lines (the date should reflect your installation time).

#----- 29 Jun 2005: HP Insight Management Agents

# ----- 29 Jun 2005: end modifications

NOTE: Any remote host names you configured during initial installation appear in this

file. Record these remote host names for later use in “Advanced Troubleshooting Steps”

(page 23).

2. Find the directives for local host community strings.

In the following example, ROlocal and RWlocal are used as a generic representations of

the names you set for the read-only and read-write community strings, respectively. The

names in your file appears as you configured them when you installed the HP Insight

Management Agents.

rocommunity ROlocal 127.0.0.1

rwcommunity RWlocal 127.0.0.1

Ensure the values of ROlocal and RWlocal are what you thought you set for local host

community strings when you configured or reconfigured your agents. Each community

string must have a unique string value. If you need to change them, see the instructions in

“Reconfiguring HP Insight Management Agents” (page 17).
