How to get the DNS for 3G network? #146

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
I want to use 3G card in android like Issue80. When I run the pppd script, I 
got the "CONNECT", but didn't surf the internet.   
/ # netcfg
ppp0     UP    10.134.76.60    255.255.255.255 0x000010d1

/ #ping www.sina.com.cn
ping: unknown host www.sina.com.cn

/ #getprop

I can surf the net now. I added a static DNS, then the network was OK.

I had resolved this problem after deleted the "ANDROID_CHANGEDS" in the 
create_resolv() function.

hi Erin,

Should we integrate yufeng's changes in 0xdroid?

Hi there, 
How is your ip-up script? does it set DNS property?
like below:
setprop "net.dns1" "$DNS1"
setprop "net.dns2" "$DNS2"
setprop "net.$NAME.local-ip" "$IPLOCAL"
setprop "net.$NAME.remote-ip" "$IPREMOTE"

I saw your comment#4, you marked "ANDROID_CHANGES" out in create_resolv. I 
guess you create a resolv.conf in /etc/ppp folder, right?

Erin：
   My ip-up script is at the same as yours. It set the DNS for network. And I didn't create the resolv.conf because of the "ANDROID_CHANGEDS" close this action.
   Thanks! Erin.

Hi there, 
mmh... i see. You marked that define out, then it can create resolv.conf 
correctly.
