Forwarded email 1/2 - usermode networking in android on fast models.  This
should cover 99% of what we want, unfortunately if you ever want to ping
something, it will not work.

 Hi all,****

** **

I don?t know if its generally known about, but you can use user mode
networking with models from v 7 onwards. There are some limitations and (at
least in my experience so far) connections occasionally drop, but
personally I could not configure TAP and a bridge without my desktop
locking up, so it was a vast improvement for me. When it connects, ADB
works over this connection and you can use that to set up other forwarding
tunnels as necessary.****

This is the setup I?ve been using:****

** **

additional model command line options:****

-C motherboard.hostbridge.userNetworking=true -C
motherboard.hostbridge.userNetPorts="5555=6565" -C
motherboard.smsc_91c111.enabled=1****

** **

adb options on guest os:****

(taken from https://wiki.linaro.org/Platform/Android/SetupAdbOverTcp - can
be added to the init script too)****

stop adbd****

setprop service.adb.tcp.port 6565****

start adbd****

** **

adb options on host OS:****

export ADBHOST=127.0.0.1****

sudo android-sdk-linux_x86/platform-tools/adb start-server****

adb connect localhost****

Best Regards,****
