If I start it after booting it appears to work. But on boot I get this during the boot sequence: Starting dhcpcd. dhcpcd-10.0.8 starting igb0: link state changed to UP igb1: link state changed to UP no interfaces have a carrier Additional TCP/IP options: IPv6 CPE WANIF=igb0. Setting up harvesting: [CALLOUT],[UMA],[FS_ATIME],SWI,INTERRUPT,NET_NG,[NET_ETHE R],NET_TUN,MOUSE,KEYBOARD,ATTACH,CACHED Feeding entropy: dd: /boot/entropy: Read-only file system . igb0: link state changed to DOWN Setting hostname: IpGw.Denninger.Net. ELF ldconfig path: /lib /usr/lib /usr/local/lib /usr/local/lib/ipsec /usr/local/ lib/perl5/5.36/mach/CORE 32-bit compatibility ldconfig path: /usr/lib32 /usr/lib32 lo0: link state changed to UP igb1: link state changed to DOWN Starting Network: lo0 igb0 igb1 enc0. igb0: link state changed to UP Which would be ok EXCEPT all I get is an IPv4 address and its not repeatable either -- which it IS using DHCP provided by the system (that is, I RARELY get a different one -- with dhcpcd I ALWAYS get a different one. I'd prefer not to; obviously if I must then I must, but it appears dhcpcd is not maintaining any sort of requested ID and thus even if the server CAN give me the same IP, it doesn't.) But more troubling I don't get an IPv6 at all. The reason appears to be that the default route doesn't get populated off the other end, and I note that "ACCEPT_RTADV" is NOT there -- and neither is "AUTO_LINKLOCAL". If I stop it from /usr/local/etc/rc.d with "dhcpcd stop" and then "dhcpcd start" I *do* get the IPv6 delegation. Gotta put it back on the other setup for now, but any ideas would be helpful - I can't take the connection offline for the next couple of days, but can work on it over the weekend. -- Karl Denninger karl@denninger.net /The Market Ticker/ /[S/MIME encrypted email preferred]/
