org.apache.commons.net.CharGenTCPClient
| CharGenTCPClient | | final public class CharGenTCPClient extends SocketClient (Code) | | 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
org.apache.commons.net.SocketClient.connect connect and call
CharGenTCPClient.getInputStream getInputStream() to access
the data. Don't close the input stream when you're done with it. Rather,
call
org.apache.commons.net.SocketClient.disconnect disconnect to clean up properly.

The default constructor for CharGenTCPClient. |
| CHARGEN_PORT | | final public static int CHARGEN_PORT(Code) | | The character generator port value of 19 according to RFC 864. **
|
| DEFAULT_PORT | | final public static int DEFAULT_PORT(Code) | | The default chargen port. It is set to 19 according to RFC 864. **
|

| CharGenTCPClient | | public CharGenTCPClient()(Code) | | The default constructor for CharGenTCPClient. It merely sets the
default port to DEFAULT_PORT .
|
| getInputStream | | public InputStream getInputStream()(Code) | | 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
org.apache.commons.net.SocketClient.disconnect disconnect to clean up properly.
An InputStream from which the server generated data can be read. |
