HP Smart Update Manager leverages the IPv6 capabilities of Linux as provided by the Red Hat Enterprise Linux and Novell SUSE Linux Enterprise Server products. Using HP Smart Update Manager in this environment enables you to use all the capabilities of IPv6 including link-local, site-local, and global IP addresses for both local and remote target servers. Remote target servers must have the iptables-ipv6 RPM installed before targeting them from HP Smart Update Manager. Failure to install the iptables-ipv6 RPM prevents HP Smart Update Manager from opening the communications port needed to send data to the initiating Linux workstation. You can disable the Linux firewall to allow HP Smart Update Manager to work, but the Linux server becomes vulnerable to attack.
For information on how to setup IPv6 in a Linux environment, please see the Linux IPv6 How-To.
IPv6 addresses can be passed to HP Smart Update Manager in command line arguments or using the HP Smart Update Manager user interface. In the HP Smart Update Manager user interface, you can add a remote host on an IPv6 network by either entering the DNS name of the IPv6 target server or by selecting the IPv6 address button and entering the IPv6 address. HP Smart Update Manager supports both the short-name and full IPv6 notation. You do not need to add the optional interface number when you enter the address.
If you cannot connect to the target server or receive a Discovery failed message when executing HP Smart Update Manager in an IPv6 environment, see the troubleshooting section.
After you connect to the target server, all other HP Smart Update Manager functions work identically. Log files for IPv6 hosts are stored with all other HP Smart Update Manager files in the /var/hp/log/<ip_address> directories.
