Take the part before the underscore and check: % whatis ip6addrctl ip6addrctl(8) - configure address selection policy for IPv6 and IPv Then see "man 8 ip6addrctl" for details: NAME ip6addrctl - configure address selection policy for IPv6 and IPv4 [...] DESCRIPTION The ip6addrctl utility manages the policy table of source and destination address selection for outgoing IPv4 and IPv6 packets. When ip6addrctl is invoked without an argument or with a single argument show, it prints the content of the policy table currently installed in the kernel. [...] HISTORY The ip6addrctl utility first appeared in the KAME IPv6 protocol stack kit. The original command name was addrselect, but it was then renamed to the current one so that the name would describe its function well. The manual page dating says "September 25, 2001", so it's not exactly new. ;-) -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
