| Please note that the content of this book primarily consists of articles
available from Wikipedia or other free sources online. The Character
Generator Protocol (CHARGEN) is a service is in the Internet Protocol
Suite defined in RFC 864 in 1983 by Jon Postel. It is intended for
testing, debugging, and measurement purposes. A host may connect to a
server that supports the Character Generator Protocol on either
Transmission Control Protocol (TCP) or User Datagram Protocol (UDP) port
number 19. Upon opening a TCP connection, the server starts sending
arbitrary characters to the connecting host and continues until the host
closes the connection. In the UDP implementation of the protocol, the
server sends a UDP datagram containing a random number (between 0 and
512) of characters every time it receives a datagram from the connecting
host. Any data received by the server is discarded. |
