I'm trying to learn about ICMP Router Discovery...
But, this little code snippet I found in an online tutorial isn't
catching any ICMP packets:
[snip]
It compiles and runs fine, but never catches anything. It just
sits on the read() line, waiting indefinitely.
Works fine for me (try pinging something, as a test).
I tried unplugging/replugging routers to force them to send ICMP
router advertisements, but still nothing shows up.
Are you sure that the router advertisements are being sent? Use
'tcpdump' to look at traffic on your subnet, if you haven't already.

Justin
