It was originally posted on the macnetworkprog list, but it's been VERY quiet for a few days, so I'm hoping for a little more activity on this list.] 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. 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. This email sent to site_archiver@lists.apple.com
