Dave,
I'll sign too. (And I like the 98th percentile measure for each direction to
give a single number that represents what's happening. It could include ping
loss rate, as well...)
But more importantly, an open letter would likely be more powerful than the
results I got from sending a note t

Not having coded a stitch of this, I *think* it would require the following:

Hokey pokey! CeroWrt sez... 53d 22h 38m 21s This is great!
Everything seems to be fine. mdns, routing, low bloat, etc. I have not fired up

Folks,
Not having looked at the 6in4 tunnel through Hurricane Electric since the
spring, I decided to try it again. The script on the wiki
(http://www.bufferbloat.net/projects/cerowrt/wiki) didn't work out of the box,

as a bridge, so I have CeroWrt 3.10.50-1 configured to supply the PPP
user/password. Everything's working fine. Almost.
The problem I'm seeing is that my DSL line is dropping on a regular basis.
