I have a Linux box connected to the net via a cable modem. Lately I have
been receiving a ICMP_RouterAdvert message in my system logs from icmpinfo.
The message repeats very frequently, sometimes several within a few
seconds, and takes up a lot of space in my system log files. It is
annoying me to no end. ;) I checked the ICMP RFC (1327?? can't recall
now) and it seems clear to me that this behavior violates the RFC.
The jabbering router (or whatever it is) just started this a few weeks ago.
The machine is a client on my cable modem ISP network. I called the ISP
reluctantly (didn't want to get anyone in trouble) just to see what the
scoop was. They apparently looked into and said my bandwidth shouldn't be
affected, but I still find this annoying and would like it to stop.
Does anyone have any insight as to what may be causing this, if this is
expected behavior and what I might do about it? If I have to just live
with it, I guess I can, but I'd at least like to understand the ins and
outs of what is occurring here.
