Traceroute over verizon - What changed ? Al Dykes 07-14-06

From an XP desktop via a linksys box and Verizon DSL to my appliation
server, I used to be able to use the pathping command to do a
traceroute with packet-dropped rates, per hop.

In the last few weeks, this either stops at my router or all the
intermediate hops don't tell me anything.

It looks like Verizon has turned ICMP off. I've not changed anything
from my linksys router and upstream

What changed?

You sure you didn't upgrade the firmware in your unidentified Linksys
router? This sounds like a problem they keep reinventing in their
firmware...

Nope. This router says it's firmware is 1.42.7, Apr 2. 2002.
It's a BEFSR41 v2 that's never been upgraded.

ISTM that this tracert/pathping problem has come and gone over the
last year but it seems to be solid now. All I can think of is that
the box has been power cycled occasionally due to utility power
problems.

Thanks.
