| |
With 2.4.21-pre2 I can get a nice tunnel going over my ppp connection and as such get ipv6 connectivity. I think went to 2.4.21 and then to 2.4.22-pre4 and bringing up the tunnel fails as follows:
[01:37:04] root@nessie:/usr/src/linux>> ifup --verbose sit1 Configuring interface sit1=sit1 (inet6) run-parts /etc/network/if-pre-up.d ip tunnel add sit1 mode sit remote 138.25.6.14 ip link set sit1 up ip addr add 3ffe:8001:000c:ffff::37/127 dev sit1 ip route add ::/0 via 3ffe:8001:000c:ffff::36 RTNETLINK answers: Invalid argument
Basically nothing gets through. Any attempts to ping/connect past my gw fail and pinging the external gw results in packets coming back from my gw (though with the eth0 IP addy) as if I were pinging it instead.
ie:
15 [01:41:34] hogarth@theirongiant:/home/hogarth>> ping6 3ffe:8001:000c:ffff::36PING 3ffe:8001:000c:ffff::36(3ffe:8001:c:ffff::36) from 3ffe:8002:1005::2 : 56 data bytes 64 bytes from 3ffe:8002:1005::1: icmp_seq=1 ttl=64 time=0.159 ms 64 bytes from 3ffe:8002:1005::1: icmp_seq=2 ttl=64 time=0.118 ms 64 bytes from 3ffe:8002:1005::1: icmp_seq=3 ttl=64 time=0.109 ms 64 bytes from 3ffe:8002:1005::1: icmp_seq=4 ttl=64 time=0.116 ms 64 bytes from 3ffe:8002:1005::1: icmp_seq=5 ttl=64 time=0.114 ms

Mind you, the same exact config works beautifully under 2.4.21-pre2.
If there are any patches you want me to try or help in any other way (as far as debugging goes anyways :) then holler. :)
