CharGenTCPClient

public final class CharGenTCPClient extends SocketClient
The CharGenTCPClient class is a TCP implementation of a client for the character generator protocol described in RFC 864. It can also be used for Systat (RFC 866), Quote of the Day (RFC 865), and netstat (port 15). All of these protocols involve connecting to the appropriate port, and reading data from an input stream. The chargen protocol actually sends data until the receiving end closes the connection. All of the others send only a fixed amount of data and then close the connection.

To use the CharGenTCPClient class, just establish a connection with {@link org.apache.commons.net.SocketClient#connect connect } and call {@link #getInputStream getInputStream() } to access the data. Don't close the input stream when you're done with it. Rather, call {@link org.apache.commons.net.SocketClient#disconnect disconnect } to clean up properly.

        setDefaultPort(DEFAULT_PORT);
Methods Summary
public java.io.InputStreamgetInputStream()
Returns an InputStream from which the server generated data can be read. You should NOT close the InputStream when you're finished reading from it. Rather, you should call {@link org.apache.commons.net.SocketClient#disconnect disconnect } to clean up properly.

return
An InputStream from which the server generated data can be read.

        return _input_;
