[Cerowrt-devel] 3.8.13-6 No name resolution over wireless

[Cerowrt-devel] 3.8.13-6 No name resolution over wireless

[Fred Stratton]

Taeht wants all User posting on this list.

I am not a developer, though you need a certain skill set to manipulate Cerowrt as a user.

The weather here is good, whilst the rest of Europe drowns, and poorer wireless reception has come with the sunshine, which hampers troubleshooting.

This build works better on ADSL, so I am reluctant to regress to an earlier one.

Ethernet connected clients work as expected.

Wireless clients connect, but neither Ubuntu 12.04.2 nor ML machines can resolve URIs.

I suspect this is a configuration problem. /etc/config/wireless is difficult to understand with so many routed interfaces.

3.8.13-5 did not have the problem.

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.

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
pending.

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.

Sounds like a regression that was in OpenWrt HEAD for a short time
(fixed now). Once Dave pulls in the new version, it should work again.

Thank you for the explanation, FF. 

A PC connected by ethernet appeared to not renew its lease this morning., which chimes with what you say. At that point, I went back to the previous Cerowrt build, in which I have replaced /usr/lib/aqm with the latest scripts.

DT:

You have a User. It is I. If something does not work, I report it. 

I have been doing this since I was put in a room with a PDP-8 as a student.

Your AQM efforts are better demonstrated if they are on a functioning device.

A major issue is whether constantly upgrading components alongside your efforts helps or hinders those efforts. That is your decision to make.

Concerning your rrul test request, it will be interesting to see if others can successfully connect devices to the latest build.

(Edited to be grumpy)
