Actually, traceroute uses UDP probe packets by default and more and more 
hosts filter them out.  I have a workaround for that:

traceroute -I risingstarmbc.com

This uses ICMP Echo packets instead, which are more likely to get 
through.  However, you either need to be root for that, or SUID on /bin 
/traceroute, which is what I did because I'm the only person using this 
machine; I'd not do it on a production box just on general principles. 
In fact, I have an alias for it in .bashrc:

alias tracert=traceroute -I

which works fine.  (On a production box, I'd put the alias in root's 
.bashrc and use su -c to invoke it.)
