Hi Jon,

I'm afraid that you need to run this command in console to enable the DNS:

setprop net.dns1 192.168.1.1 (192.168.1.1 is my wireless router)

Please refer to the comment #10 of this bug: https://bugs.launchpad.net/linaro-android/+bug/894502 FYI.

Yes, thanks Kejun. :-) I have a question though...

I can see the Settings menu has options for Ethernet now, and it defaults to DHCP, which is good. However, after booting my vexpress it doesn't have an active network connection. I also tried changing the config and enabling/disabling ethernet. Is there some more plumbing that needs adding, or something I need to add to my device config to get ethernet working?

(Additional info, I can still bring up a network from the commandline with "netcfg eth0 dhcp", but DSN resolving doesn't work, and the UI doesn't recognise there being a network. This was the situation before ECM was added.)

Thanks

Hi Jon, Ethernet should be auto enabled after entering android word. The green LED on the Ethernet port should be blinking if the cable is plugin before the Linux booting (This is not related with the ECM). The yellow LED should be on if the Ethernet is enabled by checking the ECM setting box.

If the cable is not plugin before the Linux booting, you need to disable then enable the Ethernet by unchecking then checking the ECM box. Once the green LED has blinked, unplug then plugin the cable can make the green LED off then blinking.

BRs, Kejun ZHOU

There is not special config for other devices.

Actually, checking again, the network is enabled but DNS lookups don't work.

Logcat shows EthernetStateMachine successfully doing a DHCP lookup and getting a DNS server address, but I guess this doesn't get fed into the net.dns1 property.

On Gingerbread, I notice that it's EthernetStateTracker which drives the DHCP lookup, and this works for me.

Both EthernetStateMachine and EthernetStateTracker seem to do similar jobs and have similar code, and both are running on ICS and Gingerbread.

I'll try and find some time to do some investigation.

Tixy, if you disable and re-enable Ethernet does it work?

Kejun, where is the net.dns1 property getting written.

This should work out of the box.

Mathieu, did you run into this issue?

It doesn't.

K, thanks for checking. We can modify it to write that prop. Kejun, can you take a look? Tixy, would you mind filing a bug?

Thanks Kejun!

I created a bug: https://bugs.launchpad.net/linaro-landing-team-arm/+bug/915434

Cool. I assigned the bug to Kejun.

I notice that configureInterface() triggers DHCP for ETHERNET_CONN_MODE_DHCP else it sets static IP values which includes:

SystemProperties.set("net.dns1", info.getDnsAddr())

At least in frameworks/base, the only other place which I can find which might set DNS is updateDns() in frameworks/base/services/java/com/android/server/ConnectivityService.java which gets called from handleConnectivityChange().

I have never looked at Android code or programmed in Java before, so I'll stop looking there and get on with other things for the moment.

Java is fun! Its like being in a warm, someone else handles your memory blanket!
