- Verify that you can establish an SSH connection to the remote target server using the credentials within HP SUM by issuing the following command at a console prompt: - 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: 
- Ensure you can ping the IPv6 loopback address: 
- Use the DNS hostname instead of IPv6 address to ensure the address is correct. 
- Use - ipconfigto 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 SUM properly finds the remote target server without any issues. 
- HP SUM can always be copied to the target servers and executed using the local installation method.
