Troubleshooting 40
• For Linux, ensure that the target server can be contacted through SSH and that the scp command is
available to securely send files to the target server.
• Ensure the firewall ports on any routers in the network as documented in the Enabling ports in HP
Smart Update Manager section of this document.
• The Symantec End Point Protection product (SEP) blocks HP Smart Update Manager ability to
communicate with remote targets if the Network Threat Analysis feature is enabled. Disable this
feature while HP Smart Update Manager is in use on the workstation.
• Examine the OpMan.trace, IPScout.trace, OSScout.trace, discagent.trace and discmanager.trace
files to determine the cause of the failure. For more information, see Collecting trace directories.
Recovering from a loss of Linux remote functionality
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 Smart Update Manager to deploy firmware. For a list of
the ports that need to be configured in the firewall, see Allowing ports in HP Smart Update Manager
(" Enabling ports in HP Smart Update Manager " on page 41 ).
