+
+## Introduction
+
+Stagehand is an open source tool that allows a developer to:
+
+- Connect to a DALi application running on:
+ - Tizen
+ - Ubuntu
+- View a wireframe of the current scene on top of a screen shot
+- Modify properties in the scene
+- Monitor performance of the application
+
+
+Full source code is available from http://github.com/gamoeba/stagehand.git
+
+Stagehand is released under the Apache 2 licence.
+
+## Installing StageHand on Ubuntu
+
+http://www.gamoeba.com/stagehand/
+
+Install both files on the website. Start with the QT dependencies first.
+
+
+## How it works
+
+Stagehand connects to DALi via the network using a TCP/IP connection.

+
+## Network setup
+
+To enable network control on DALi, an environment variable must be set:
+
+~~~
+$ export DALI_NETWORK_CONTROL=1 to enable
+~~~
+Or run the application with the variable set.
+~~~
+$ DALI_NETWORK_CONTROL=1 /usr/apps/com.samsung.dali-demo/bin/dali-demo
+~~~
+
+Check what network port the application is using. It will be from port 3031 onwards.
+
+If running DALi on desktop, just type netstat -tlnp. On Tizen log into the device and run netstat. E.g.
+~~~
+$ su
+
+$ netstat -tlpn

+
+## Performance monitoring
+
+To enable performance option. Edit
+
+~/.stagehand/stagehand.ini
+
+Set perfmode=on
+
+Restart application. Click performance

+
+## Trouble shooting
+
+You can manually check the network is enabled on the DALi application using netcat.
+
+In the example below we are connecting to a Tizen device using SDB port forwarding.
+
+After running nc localhost 3031 we type help

+
+
+## Tizen smack
+
+
+If you can't connect to a DALi application, but using netstat you can see a port is open.
+
+Check the smack log for errors:
+~~~
+tail -f -n 10 /var/log/audit/audit.log | grep 'internet'
+~~~
+
+If it is being blocked, you temporarily enable it by editing:
+
+~~~
+ /etc/smack/accesses2.d/ your-app-name
+
+then add: system::user_internet …..app-name rw
+~~~
+## Tizen Emulator connection problem
+
+
+Make sure DALi application is run using launch_app:
+~~~
+launch_app [APP_ID] __AUL_SDK__ DEBUG __DLP_DEBUG_ARG__ :10003
+~~~
