Many motherboards nowadays have integrated gigabit ethernet that use the Realtek NIC chipset.
The Realtek r8168B network card does not work out of the box in Redhat/Centos 5.3: instead of loading the r8168 driver, modprobe loads the r8169 driver, which is broken as can be seen with ifconfig which shows large amounts of dropped packets. A solution is to download the r8168 driver from the Realtek website and install it using the following steps:
Check whether the built-in driver, r8169.ko (or r8169.o for kernel 2.4.x), is installed.
# lsmod | grep r8169
If it is installed remove it.
# rmmod r8169
Download the R8168B linux driver from here into /root.
Unpack the tarball :
# cd /root
# tar vjxf r8168-8.012.00.tar.bz2
Change to the directory:
# cd r8168-8.012.00
If you are running the target kernel, then you should be able to do :
# make clean modules
# make install
# depmod -a
# insmod ./src/r8168.ko (or r8168.o in linux kernel 2.4.x)
make sure modprobe knows not to use r8169, and that depmod doesn’t find the r8169 module.
# echo "blacklist r8169" >> /etc/modprobe.d/blacklist
# mv /lib/modules/`uname -r`/kernel/drivers/net/r8169.ko \ /lib/modules/`uname -r`/kernel/drivers/net/r8169.ko.bak
You can check whether the driver is loaded by using the following commands.
# lsmod | grep r8168
# ifconfig -a
If there is a device name, ethX, shown on the monitor, the linux driver is loaded. Then, you can use the following command to activate it.
# ifconfig ethX up
After this you should not see any more dropped packets reported.
echo "Hello world\n"

In this article Barry Mavin explains step by step how to setup a Linux HA (High Availability) cluster for the running of Recital applications on Redhat/Centos 5.3 although the general configuration should work for other linux versions with a few minor changes.
The getUIComponentBitmapData method can create bitmapdata for a given IUIComponent. Pass any UIcomponent to get its respective bitmapdata.
public static function getUIComponentBitmapData(target:IUIComponent):BitmapData {
var resultBitmapData:BitmapData = new BitmapData(target.width, target.height);
var m:Matrix = new Matrix();
resultBitmapData.draw(target, m);
return resultBitmapData;
}
Now convert the bitmapdata to a jpeg bytearray.
private static function encodeToJPEG(data:BitmapData, quality:Number = 75):ByteArray {
var encoder:JPGEncoder = new JPGEncoder(quality);
return encoder.encode(data);
}
Now encode the ByteArray into Base64.
public static function base64Encode(data:ByteArray):String {
var encoder:Base64Encoder = new Base64Encoder();
encoder.encodeBytes(data);
return encoder.flush();
}
Upload the base64 encoded ByteArray to the server.
public static uploadData():void {
var url:String = "saveFile.php";
var urlRequest:URLRequest = new URLRequest(url);
urlRequest.method = URLRequestMethod.POST;
var urlLoader:URLLoader = new URLLoader();
var urlVariables:URLVariables = new URLVariables();
urlVariables.file = jpgEncodedFile; // as returned from base64Encode()
urlLoader.data = urlVariables;
urlLoader.load(urlRequest);
}
The saveFile.php file on the server.
