Simple TCP/IP Services provides support for the optional TCP/IP protocol services listed in the following table.

Protocol Description RFC

Character Generator (CHARGEN)

Sends data made up of the set of 95 printable ASCII characters. Useful as a debugging tool for testing or troubleshooting line printers.



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.



Discards all messages received on this port without response or acknowledgment. Can serve as a null port for receiving and routing TCP/IP test messages during network setup and configuration or, in some cases, can be used by programs as a message discard function.



Echoes back data from any messages it receives on this server port. Echo can be useful as a network debugging and monitoring tool.


Quote of the Day (QUOTE)

Returns a quotation as one or more lines of text in a message. Quotations are taken at random from the following file: systemroot\System32\Drivers\Etc\Quotes. A sample quote file is installed with the Simple TCP/IP Services. If this file is missing, the quote service fails.


All of these protocol services are classified as elective Internet standards and are defined and described in the specified Request for Comments (RFC) document listed in the table. For more information about these protocol services, see the RFCs.


Do not install Simple TCP/IP Services unless you specifically need this computer to support communication with other systems that use these protocol services.


After Simple TCP/IP Services are installed, you cannot enable or disable the separate services individually.
