Re: Odd log message

*Edit* I believe I found what it is: It is an Internet Control Message Protocol version 6 (ICMPv6) "Router Advertisement" packet

rtadvd is the RouTerADVertisementDaemon

From the Neighbor Discovery Protocol Wikipedia entry:

1.Router Solicitation - used by hosts to locate routers on an attached link.[Definitions 1] Nodes which forward packets not addressed to them generate Router Advertisements immediately upon receipt of this message rather than at their next scheduled time.
2.Router Advertisement - used by routers to advertise their presence together with various link and Internet parameters either periodically, or in response to a Router Solicitation message

You're on your own after that heh. Took me a bit to find that and I'm tired.

Thanks, but I already know what they are.

What I don't understand is why they are flooding my log and what I can do to get it stopped or ignored without logging.

Thanks, I know what the rtadvd packet is, as I run rtadvd for my internal network to mete out IPv6 addresses.

I just don't know why I am seeing those packets coming in from the cable modem.
