Limitations of IPv6 for Linux
The only current limitation of HP Smart Update Manager in a Linux IPv6 environment is that all remote
target Linux-based servers must have the iptables-ipv6 rpm file installed. You can find the file on the
distribution media for both Red Hat Enterprise Linux and Novell SUSE Linux Enterprise Server operating
systems. HP Smart Update Manager uses this file to open a port in the IPv6 firewall to communicate with
the Linux system that runs HP Smart Update Manager. Failure to install iptables-ipv6 results in HP Smart
Update Manager reporting a discovery failure unless you disable the firewall.
