HTC Incredible S (???????????? - no permissions)

Unlike other popular devices (e.g. S2 i9100), some HTC phones require certain configuration in order to work properly under the context of Linux (e.g Ubuntu Quantal Quetzal).

#Android SDK is required to use "adb" 

$ adb devices
List of devices attached
???????????? no permissions 

In the case of HTC Incredible S, hardware definition is needed.

$ lsusb

Bus 001 Device 009: ID 0bb4:0cac HTC (High Tech Computer Corp.)

where

"obb4" is the vendor ID
"0cac" is the product ID

Create or edit the following file

$ sudo gedit /etc/udev/rules.d/51-android.rules

Add the following line and save it

SUBSYSTEMS=="usb", ATTRS{idVendor}=="0bb4", ATTRS{idProduct}=="0cac", MODE="0666"

Restart the service

$ sudo restart udev

$ adb devices
List of devices attached
HT13WRD00413    device  

You may need to unplug the device from your computer before restarting the service. Restarting adb may be also needed ($adb kill-server/start server). More HTC configurations can be found in this link

Deploying Tsung in a Cluster

Tsung is a load testing tool that allows you to simulate heavy loads of users. Installing it in a single node, its an easy task. However, when the load achieved by a single node its not enough for testing purposes, then it is necessary to deploy Tsung in different nodes, which makes the process a bit complicated.

This post attempts to explain you, how to deploy Tsung in multiple nodes (3 nodes). 1 controller and 2 secondary nodes. Notice that the controller manages/collects the information of the whole simulation process.
