Class Client

java.lang.Object

  +--Client

All Implemented Interfaces:

java.lang.Runnable

public class Client

extends java.lang.Object

implements java.lang.Runnable

Note: This class must be compiled and run with Java version 1.4 or later.

This class reproduces a denial of service attack by sending urgent data. It connects to a server on the specified host and port and then exchanges messages with the server, checking that each message returned is identical to the one sent. Each message sent is followed by an urgent data byte. Invoke this program from the command line with:

 java Client [-h host] [-p port] [-n number] [-c count] [-v]
 

where:

-h host

is the name of the host where the server is running. The default is localhost.

-p port

is the port on which the server accepts connections. The default is 8000.

-n number

is the number of simultaneous clients to create. The default is 1.

-c count

is the count of messages each client sends. The default is 10.

-v

enables verbose output in which the program prints each message received. The default is no verbose output.
