openbsd and rtadvd
![[nl]](/s/countries/nl.gif) Shadow Hawkins on Thursday, 06 November 2003 22:36:15
I am running openbsd 3.3 and am trying to get rtadvd up and running for my subnet, which is 2001:838:364::/48.
I have assigned 2001:838:364:1::1 to fxp0 (which is my localnet if).
This is the rtadvd.conf I got:
fxp0:\
:addrs#1:addr="2001:838:364:1::":
--
sysctl -w net.inet6.ip6.forwarding=1 (enabeling ip6 forwarding seems to be necessary according to this error msg in /var/log/daemon:
Nov 6 21:02:00 xxxx rtadvd[2810]: <getconfig> non zero router lifetime is specified for fxp0, which must not be allow
ed for hosts. you must change router lifetime or enable IPv6 forwarding. )
I started it using the -d parameter: rtadvd -d fxp0, it seems to be up and running .
In /var/log/daemon this line shows up (and keeps showing up):
Nov 6 22:21:48 xxxx rtadvd[27766]: <ra_output> sendmsg on fxp0: No route to host
After al this I tried to get an ip6 number on my other machine (openbsd 3.4) using "rtsol fxp0" nothing seems to happen.
After this I tried "rtsol -d fxp0" for some more verbose output which is:
checking if fxp0 is ready...
fxp0 is ready
send RS on fxp0, whose state is 2
send RS on fxp0, whose state is 2
send RS on fxp0, whose state is 2
No answer after sending 3 RSs
stop timer for fxp0
there is no timer
---
I don't have a clue where to go next. Anyone any suggestion?

See Using Subnets on *BSD (KAME) which describes the correct format of the rtadvd.conf file. Next to that did you route the /64 to that interface?

I used the format described in the faq. Know I get this error:
# rtadvd -fd fxp0
rtadvd[27582]: <getconfig> fxp0 isn't defined in the configuration file or the configuration file doesn't exist. Treat it as default
rtadvd[27582]: <getconfig> need addr as a prefix for interface fxp0
My /etc/rtadvd.conf looks like this:
# cat /etc/rtadvd.conf
fxp0:\
:addrs#1:\
:addr="2001:838:364:2::":prefixlen#64\
:tc=ether:
--
My fxp0 has ip6 inet6 2001:838:364:2::1 prefixlen 64
(ifconfig fxp0 inet6 2001:0838:0364:0002::1 prefixlen 64 alias)
I've setup my route for the subnet like this:
route add -inet6 2001:838:364:: -prefixlen 64 2001:838:300:bc::2
Any clue on the rtadvd error? (and is the routing correct?)
openbsd and rtadvd
I've setup my route for the subnet like this: route add -inet6 2001:838:364:: -prefixlen 64 2001:838:300:bc::2
Thus you are routing the subnet over the tunnel instead? :)
You should nullroute the /48:
# route add -inet6 2001:838:364:: -prefixlen 48 ::1
And only configure the /64 on fxp0 and it should work...

I feel pretty stupid right now |:(
but, I deleted the routing and made the nullroute. Fxp0 now has inet6 2001:838:364:2::1 prefixlen 64.
I didn't changed the /etc/rtadvd.conf but started it in a differentway.
# rtadvd -c/etc/rtadvd.conf fxp0
# ps -awx |grep rtadvd
11118 ?? Is 0:00.00 rtadvd -c/etc/rtadvd.conf fxp0
15958 p1 I+ 0:00.00 grep rtadvd
the process is running.
In /var/log/daemon this shows up:
Nov 8 17:35:09 xxxx rtadvd[11118]: <ra_output> sendmsg on fxp0: No route to host
Looks like we're back to the old problem ...
Did I miss anything?

*OOPS*
did I mention I didn't change my fw? O-)
I've just editted my fw (remote) and the message to /var/log/daemon doesn't show up anymore. Will try tomorrow to see if it works when I allow inet6 for fxp0 })

Ok, I feel really stupid right now :(
Looks like it was my fw afterall. I allowed everything in and out for inet6 on fxp0. Restarted the rtadvd, no warning in /var/log/daemon this time.
I tried my client (openbsd 3.4)
sjaak# rtsol -d fxp0
checking if fxp0 is ready...
fxp0 is ready
send RS on fxp0, whose state is 2
received RA from fe80::2d0:b7ff:fee7:d046 on fxp0, state is 2
As you see it got an ip from the advertisment daemon
HIT ME PLEASE |:(
