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

  • 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?

  • 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?

  • 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?

  • 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??

  • Update - General System Logs also states:
    Note- my logs are latest first.
