Recovering from a loss of Linux remote functionality by configuring firewall
settings
When the Unable to Access Host message appears, the target firewall is enabled. By default,
the target firewall is enabled in Linux.
To recover remote Linux functionality, the target and host firewall must be disabled or reconfigured
to allow IP traffic through the ports needed by HP SUM to deploy firmware. For a list of the ports
that need to be configured in the firewall, see

Recovering from a blocked program on Microsoft Windows

There are two ways to recover from a blocked program when using Windows:
"Configuring Windows firewall settings" (page 31)
"Enabling ports in HP SUM" (page 33)

Configuring Windows firewall settings

The Windows Security Alert appears when a program is blocked from accepting connections from
the Internet or a network.
To set the rules for the Windows Firewall and Security Policy, click Unblock, and then set your
firewall settings to the following:
1. Click Start Control Panel Administrative Tools Windows Firewall with Advanced
Security Inbound Rules Remote Administration (NP-IN).
2. Select Enabled, and then select Allow the connections.
For Direct-to-iLO support, you must enable Ping.

Network ports used by HP SUM

HP SUM requires that certain network ports are available for proper operation. If you lock down
network ports, remember to ensure that the ports listed in the network port tables are open so that
HP SUM works correctly when connecting to remote target servers and hosts. If you are unable to
unlock these network ports, the only option is to run HP SUM locally and update network-based
hosts, such as the OA, iLO, and VC, through their web interfaces.
