View Full Version : Traceroute questions

26th July 2007, 04:48 AM
Can someone explain to me why traceroute uses UDP datagrams for probes?

The firewall in my router doesn't seem to allow these packets back in once they leave.

I would like to be able to run traceroute as a user instead of root (since running as root is the only way to use ICMP echo instead of UDP).

Any info would be greatly appreciated.
