strange installation issue
hi
(i do not yet use debian on any of those machines. however i have no
idea where to ask besides this list)
i want to setup the following:
3ffe:2029:8400:0:1::1 - openbsd 3.1-stable router
\--- 3ffe:2029:8400:0:1::2 - linux usagi 2.2.19 box
\--- 3ffe:2029:8400:0:1::3 - normal linux 2.2.19 box
i have no problem configuring the addresses:
--(openbsd: $:~)-- ifconfig xl0 inet6
xl0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500
media: Ethernet autoselect (100baseTX)
status: active
inet6 fe80::250:daff:fe84:bf49%xl0 prefixlen 64 scopeid 0x2
inet6 3ffe:2029:8400:0:1::1 prefixlen 96
--(linux2219usagi: $:~)-- ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:A0:24:D6:AF:28
inet6 addr: 3ffe:2029:8400:0:1::2/96 Scope:Global
inet6 addr: fe80::2a0:24ff:fed6:af28/64 Scope:Link
--(linux2219: $:~)-- ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:C0:4F:95:91:B7
inet6 addr: 3ffe:2029:8400:0:1::3/96 Scope:Global
inet6 addr: fe80::2c0:4fff:fe95:91b7/10 Scope:Link
when i try to ping6 the gateway from the linux boxes it fails. (host
unreachable):
--(linux2219usagi: $:~)-- ping6 3ffe:2029:8400:0:1::1
PING 3ffe:2029:8400:0:1::1(3ffe:2029:8400:0:1::1) from \
3ffe:2029:8400:0:1::2 : 56 data bytes
>From 3ffe:2029:8400:0:1::2 icmp_seq=3 Destination unreachable: Address \
unreachable
--(linux2219usagi: $:~)-- ip -6 neigh
--(linux2219usagi: $:~)--
(the same from the linux2219 box.)
however as soon as i ping the linux box from the openbsd box:
--(openbsd: $:~)-- ping6 3ffe:2029:8400:0:1::2
PING6(56=40+8+8 bytes) 3ffe:2029:8400:0:1::1 --> 3ffe:2029:8400:0:1::2

round-trip min/avg/max/std-dev = 2.870/517.059/2028.869/771.456 ms
it makes the entries just fine and i can ping the other way around fine:
--(linux2219usagi: $:~)-- ip -6 neigh
3ffe:2029:8400:0:1::1 dev eth0 lladdr 00:50:da:84:bf:49 router nud stale
fe80::250:daff:fe84:bf49 dev eth0 lladdr 00:50:da:84:bf:49 nud stale
does anyone have an idea what it could be? is it an openbsd or a linux
problem? one thing that is special about the openbsd box is that it's
interfaces (xl0 and xl1) are bridged together. does this impose a
problem on the link local layer? does the openbsd box not answer to
queries which come into the xl0 interface?
i hope you have an idea, thank you and greetz
