Radvd[41259]: sendmsg: Can't assign requested address

[Svante]

Hi

The Routing log of my PfSense box keeps on growing with the same issue every 6 seconds or so.

radvd[41259]: sendmsg: Can't assign requested address

I dont know were to start searching for a solution. I have tried google for a few hours now but it didnt make me smarter. The router is working fine for now so this is just a want-to-know issue.

Anyone knows what this is all about?

Are you using IPv6? What are the contents of /var/etc/radvd.conf on your system?

[Svante]

I have not configured IPv6 at all.

The radvd.conf contains

Automatically Generated, do not edit

Generated config for  delegation from wan on lan

interface bridge0 {
AdvSendAdvert on;
MinRtrAdvInterval 3;
MaxRtrAdvInterval 10;
AdvLinkMTU 1500;
AdvOtherConfigFlag on;
prefix ::/64 {
AdvOnLink on;
AdvAutonomous on;
AdvRouterAddr on;
};
DNSSL home.kula.net { };
};

Looks like you have RAs enabled on your bridge0 interface. But it has no prefix, which is why it's complaining. If you go to Services>DHCPv6 Server/RA, and the tab of your bridge0 interface, do you have anything configured for RAs there?

[Svante]

OK.

The DHCPv6 Server/RA page says only "The DHCPv6 Server can only be enabled on interfaces configured with a static IPv6 address. This system has none."

It might be that i enabled IPv6 on the bridge by mistake when I created it and removed that later on. I dont remember.

Can I remove the radvd.conf?

[cmb]

Backup your config and open it in a text editor, look for <dhcpdv6>tag. If you have one, cutting out everything from <dhcpdv6>to</dhcpdv6> , save, and restore the backup, will make that stop. Deleting radvd.conf will only last until something regenerates it, which will happen pretty quickly.</dhcpdv6>

This is strange but I fixed this problem in 2.2.2 by opening the default internal interface which is actually a bridge (em1 & VPN) and using IPv6 drop down and choosing 'none' again and resaving.
The logs then stated:
radvd[39957]: removing /var/run/radvd.pid
radvd[39957]: sendmsg: Can't assign requested address
radvd[39957]: sending stop adverts
and the error hasn't returned??
