Configuring IPv6 networks
You can deploy to remote targets in IPv6-based networks for Windows and Linux target servers.
Using HP SUM with IPv6 networks presents challenges for IT administrators.
For Windows-based servers, to communicate with remote target servers, HP SUM uses either
existing credentials or the user-provided user name and password to connect to the admin$ share.
This share is an automatic share provided by Windows Server. After HP SUM connects to the
admin$ share, it copies a small service to the target server for the duration of the installation. After
this service starts, HP SUM uses this service to communicate between the local and remote target
server. During this process, HP SUM opens ports in the Windows firewall to enable HP SUM to
use SOAP calls over SSL to pass data among local and remote systems. For more information
about the ports used, see “Network ports used by HP SUM” (page 57). After the installation is
completed or canceled, HP SUM stops the remote service, removes it from the target server, closes
the port on the Windows firewall, and then releases the share to the target server admin$ share.
For Linux-based servers, to communicate to remote target servers, HP SUM starts by using the
user-provided user name and password to create a SSH connection to the target server. After the
it connects, HP SUM copies a small service to the target server for the duration of the installation.
After this service starts, HP SUM uses this service to communicate between the local and remote
target server. During this process, HP SUM opens ports in the iptables firewall to enable HP SUM
to use SOAP calls over SSL to pass data between the local and remote systems. For more information
about the ports used, see “Network ports used by HP SUM” (page 57). When the installation is
completed or canceled, HP SUM stops the remote service, removes it from the target server, closes
the port in the iptables firewall, and then closes the SSH connection to the target server.
NOTE: Windows XP clients are not supported in IPv6 networks for HP SUM deployment.
Configuring IPv6 for Windows Server 2003
For information on setting up a Windows Server 2003 operating system within an IPv6 network,
see the online Microsoft TechNet article Step-by-Step Guide for Setting Up IPv6 in a Test Lab.
Windows Server 2003 requires site-local addresses to provide the necessary file-sharing capabilities
needed by HP SUM. This means that link-local and global IPv6 addresses are not supported as
remote targets with HP SUM.
Before using HP SUM to deploy software and firmware updates to remote Windows Server 2003
servers, you must add a registry entry to enable file sharing connections over IPv6 networks. To
make the registry entry:
1. Open the Registry Editor (Regedit32.exe).
2. Locate and click the following key in the registry:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanServer\Parameters
3. On the Edit menu, click Add Value.
4. Add the following registry value:
Value name: DisableStrictNameChecking
Data type: REG_DWORD
Radix: Decimal
Value: 1
5. Close the Registry Editor.
For more information about these steps, see the Microsoft Knowledge Base Item 281308 on the
Microsoft website.
