Troubleshooting HP Smart Update Manager in IPv6 Red Hat and Novell SUSE-based Linux environments

• Verify that you can establish an ssh connection to the remote target server using the credentials within HP Smart Update Manager by issuing the following command at a console prompt:

  ssh <ipv6 address>

  ssh 2101:db8:0:1::9

  You must enter the root password for the target Linux server at the console to complete the IPv6 connection.

• Validate that you can ping the remote target server. In Linux, you need to use the ping6 command to ping IPv6 addresses: ping6 <ipv6 address>.
• Ensure you can ping the IPv6 loopback address: ping6 ::1.
• Use the DNS hostname instead of IPv6 address to ensure the address is correct.
• Use ipconfig to validate you have IPv6 addresses assigned to your NICs. For more information about troubleshooting your configuration, see the Linux IPv6 How-To.
• For more information about setting up and troubleshooting IPv6 networks, see Getting Around IPv6 by Carla Schroder.
• Move back to an IPv4 network address to ensure HP Smart Update Manager properly finds the remote target server without any issues.
• HP Smart Update Manager can always be copied to the target servers and executed using the local installation method.
