This book can be purchased on the book's official web site, at your local bookstore, or at your favorite online book retailer. Please note the disclaimer for the code provided. If you have any problems with this page, email david_makofske@yahoo.com. Errata C Examples Java Examples C# Examples Errata On Page 31, the IP address passed as an argument to mcreceive should be the same as the argument to mcsend. The correct command line is:
% mcreceive 239.255.10.10 9000
On Page 54, in the code snippet:
sock.SetSocketOption(SocketOptionLevel.Socket,
SocketOptionName.MulticastTimeToLive,
ttl); The correct socket option level should be the IP level, not the socket level. The correct code should read:
sock.SetSocketOption(SocketOptionLevel.IP,
SocketOptionName.MulticastTimeToLive,
ttl); C Examples How to Compile You should have gcc (GNU C compiler) installed for Unix-based systems. Linux, BSD: gcc -o mcsend mcsend.c Solaris: gcc -o mcsend mcsend.c -lsocket -lnsl The Winsock version comes with a makefile for a command line build, or it can be imported into Visual Studio for compilation. Chapter 2: Multicasting with C Sockets c_send_receive.tar.gz - Multicast Sender and Receiver (mcsend.c and mcreceive.c) winsock_send_receive.zip - Multicast Sender and Receiver (Winsock version) Chapter 7: Multicast Reachability and Scalability c_mping.tar.gz - Multicast Ping Program (mping.c and mping.h) c_mping2.tar.gz - Multicast Ping Program with Congestion Control (mping.c and mping.h) Java Examples How to Compile You will need to download and install the Java JDK from the java.sun.com website. All of the Java examples can be compiled by using: javac *.java and run using: java
As specified in the book, some of the Java multicast API will require JDK 1.4 or higher. Chapter 3: Multicasting with Java java_send_receive.tar.gz - Multicast Sender and Receiver (mcsend.java and mcreceive.java) Chapter 8: Application Layer Multicast and Reflectors java_reflector.tar.gz - Multicast Reflector Program (Reflector.java, ReflectorListener.java, ReflectorSender.java, PacketListenerInterface.java, Logger.java, Address.java) C# Examples How to Compile You will need to download and install the .NET Framework from the http://msdn.microsoft.com/netframework/ website. All of the C# examples can be compiled from the command line using: csc *.cs and run using: .exe You may also import the C# files into Visual Studio.NET for compilation.
