What problem? They filter ICMP requests, so traceroute doesn't work.
That's not really a problem.
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.)
