Class CharGenTCPClient
java.lang.Object
org.apache.commons.net.SocketClient
org.apache.commons.net.chargen.CharGenTCPClient
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 the others send only a fixed amount of data and then
 close the connection.
 
 To use the CharGenTCPClient class, just establish a connection with connect  and call
 getInputStream()  to access the data. Don't close the input stream when you're done with it. Rather, call
 disconnect  to clean up properly.
