![[nl]](/s/countries/nl.gif) Shadow Hawkins on Wednesday, 15 December 2004 00:52:24 eth0
inet6 addr: 2001:6f8:900:42a:204:acff:fe77:f0fc/64 Scope:Global This can't be correct. 2001:6f8:132f::/48 is your subnet not 2001:6f8:900::/48
I guess your radvd advertisement is not correct. I wonder why you don't see any errors/warnings from radvd in your syslog :?
Anyway, using something like this in radvd.conf can helpprefix 2001:6f8:132f:<insert something>::/64

Ok here's what i have done so far.
removed old ipv6 addresses from eth0
[--ifconfig--]
eth0 Link encap:Ethernet HWaddr 00:04:AC:77:F0:FC

Changed my radvd.conf
interface eth0
{
AdvSendAdvert on;
prefix 2001:6f8:132f:babe::/64
{
};
};
and here's what my radvd log file says.
[Dec 15 09:35:09] radvd: version 0.7.2 started
[Dec 15 09:35:09] radvd: no linklocal address configured for eth0
[Dec 15 09:35:09] radvd: syntax error in config file: /etc/radvd.conf
And if i do make a inet6 addr: fe80::a00:6/64 Scope:Link on eth0
radvd says this.
[Dec 15 09:47:59] radvd: version 0.7.2 started
[Dec 15 09:47:59] radvd: another radvd seems to be already running, terminating
But of course i can't find it.

Why did you remove the link address (based on the MAC address) from eth0? As far as I know, your clients will use that for their route, (correct me if I'm wrong)
You should do restart eth0 if you change this kind of things.
1) ifdown eth0 (maybe sixxs too ?)
2) change radvd.conf (I have "prefix 2001:838:33d:0::0/64" in my .conf file)
3) (re)start radvd (if error goto 2 :P )
4) ifup eth0
5) check everything }) and post some of them here.
6) goto 1 if needed

-Check that the adresses distributed to the clients are from the correct subnet
-What does ifconfic and ip -6 route say on a client?
