Simple TCP/IP Services Simple TCP/IP Services implements support for the Echo, Discard, Character Generator, Daytime, and Quote of the Day protocols. Echo (port 7, RFC 862) This protocol echoes back data from any messages it receives on this server port. Echo can be useful as a network debugging and monitoring tool. Discard (port 9, RFC 863) This protocol discards all messages received on this port without response or acknowledgment. It can serve as a null port for receiving and routing TCP/IP test messages during network setup and configuration or, in some cases, it can be used by programs as a message discard function. Character Generator (CHARGEN) (port 19, RFC 864) This protocol sends data made up of the set of 95 printable ASCII characters. It is useful as a debugging tool for testing or troubleshooting line printers. Daytime (port 13, RFC 867) This protocol returns messages containing the day of the week, month, day, year, current time (in hh:mm:ss format), and time-zone information. Some programs can use the output from this service for debugging or monitoring variations in system clock time or on a different host. Quote of the Day (port 17, RFC 865) This protocol returns a quotation as one or more lines of text in a message. Quotations are taken at random from the following file: systemrootSystem32DriversEtcQuotes. A sample quote file is installed with Simple TCP/IP Services. If this file is missing, the quote service fails.
