5 Troubleshooting

This section provides instructions for troubleshooting basic agent installation and configuration
issues. The following assumptions have been made to develop this information:
□ The agents are not responding to inquiries from HP SIM.
□ You are a Linux system administrator with root privilege.
□ No errors were issued during agent installation and initial configuration.
□ The net-snmp-utils RPM, part of the agent installation tar archive, was installed on the
managed system.
□ Commands and options are capitalized correctly.
□ You have access to several terminal windows and you have multiple command lines available.
□ You understand that shutting down the firewall to troubleshoot creates a security breach,
and you assume all risks inherent with that procedure.
NOTE:
is on a private, secure network.

Important Information About Firewalls and Troubleshooting

Some Linux distributions automatically configure firewall software during installation, usually
using iptables, which is the standard Linux kernel's method of providing firewall support.
Such a firewall configuration may block remote management stations from contacting the SNMP
daemon, making it difficult to troubleshoot HP Insight Management Agents.
To execute the troubleshooting steps in this document, you must shut down firewall software
on the managed server using the following steps. The information in the

exists.
HP views all SNMP traffic as unsecure. Therefore, it is assumed that SNMP traffic
