[Eug-lug] Help with a Comcast test?

[Bob Carlson]

I don't know about mtr and have not tried it. I'll look it up. We have
SunRocket for our home phone, which my wife uses. I also have a VOIP
extension from  an Asterisk server in San Francisco.

 

Cheers, Bob

Have you already run mtr (multi-traceroute) tests?  mtr is r0x0r.  :)
I assume you're running your own VoIP, not Comcast's own phone,
which runs sideband and gets routed by them...?

if you need a public Iperf server.  I haven't used it in a while, but
the page look like it is still there.
