No, just posts about dev versions. I note that what you are fiddling with
is not even a released dev version. Toke's doing builds too but he's trying
to finish a thesis...

I REALLY appreciate the testing but I'm not planning on installing anything
myself until after the adsl fixes for htb stablize, and not until after
june 17th regardless. (I do try to keep up with openwrt head so as to
minimize problems with CI (continuous integration)).

The only things different in -6 are a newer dnsmasq, some aqm script
improvements, and a patch for 6in4 stuff... hmm, I should mention that.

yep! It's not for grandma yet!

I am glad to be back at the yurtlab where all the code in use is cero.

the aqm code continues to evolve. What is in the next build has been
more thoroughly tested (on an atom box) but Jesper's ADSL fix remains

Hmm. I note there is a bug in dnsmasq here under tcp, fixed in the latest
test release of dnsmasq, but I don't understand what's going on for you.

Do your wireless clients get a dns server? what does nslookup report?

there was an update to dnsmasq in this non-release, but so far as I knew it
was a fix, not a regression.
