Hi, Running 5.5 (And no "upgrade" messages please, I'm forced to, its out of my hands) and trying to bring up HE's IPV6. I've got it running on a 4.10 system (Ok, feel free to tell me to upgrade, this one is more a lazy issue.. But I am making progress. I bought new drives that'll be here next week so I can load 7.0 from scratch) with no worries at all. Piece of cake, has been for ages. But once I brought it all up, I got : kernel: nd6_lookup: failed to add route for a neighbor(2001:0470:0007:0028::0001), errno=17 and ALOT of them. Taking a quick look in Google, it seems that they claim its a prefix len issue, but I am running with a 128 prefix length even though it seems they say : Client IPv6 address: 2001:470:7:28::2/64 The script they suggest, and I used, is : ifconfig gif0 create ifconfig gif0 tunnel MYIP 216.66.22.2 ifconfig gif0 inet6 2001:470:7:28::2 2001:470:7:28::1 prefixlen 128 route -n add -inet6 default 2001:470:7:28::1 ifconfig gif0 up The tunnel came up, was passing traffic, but those messages were getting out of hand. I tried a prefixlen of 64, and I got: ifconfig: ioctl (SIOCAIFADDR): Invalid argument Sendmail seemed a bit cranky : Jun 26 23:53:19 MYHOST sendmail[17543]: gethostbyaddr(IPv6:2001:470:7:28::2) failed: 1 Suggestions where to start? Thanks, Tuc
