Description 万新明 2011-10-17 08:23:18 UTC 
I use this command, traceroute-I 192.168.1.219, use tcpdump to capture packets or UDP, not ICMP protocol packets.

tcpdump-ni eth0 host 192.168.1.90 and not port 22
tcpdump: verbose output suppressed, use-v or-vv for full protocol decode
listening on eth0, link-type EN10MB (Ethernet), capture size 65535 bytes

I also noticed that traceroute -I was sending UDP packets rather than ICMP. Checked my build config and CONFIG_FEATURE_TRACEROUTE_USE_ICMP was set to n.

traceroute --help should not list the option when support isn't compiled in and
traceroute -I should report an error in that case.
