In redhat, the daytime service is built into xinetd. Its configuration files are in /etc/xinetd.d
i.e. daytime-dgram or daytime-stream. The RFC for the daytime protocol (RFC 867) is silent on the format of the daytime string.

Quote:

There is no specific syntax for the daytime. It is recommended that
it be limited to the ASCII printing characters, space, carriage
return, and line feed. The daytime should be just one line.

No options are provided to configure the daytime string.

However, you can configure xinetd to use an external utility as the daytime server by setting options in the configuration files. Thus you can write your own utility to output a daytime string in the format you want and configure xinetd to use this utility.

why daytime don't work?

Following code is detecting solaris daytime,when I run it,I can't get any result,code is follows: #include <sys/types.h> #include <sys/socket.h> #include <netinet/in.h> #include <arpa/inet.h> #include <stdio.h> #include <stdlib.h> #include <string.h> #define BUFFSIZE 150 int main(){ ...

Using Different port for Daytime Service

Hi all, is it possible to use a different port number for daytime service. By default the port number of daytime service is 13, so what if I want to get the time from a different port number e.g say 9000 (or any other port). I guess this would remain the same on the server side !...

NAME

       in.daytimed - UDP or TCP daytime protocol service daemon

SYNOPSIS

       in.daytimed

       FMRI
       svc:/internet/daytime:default

DESCRIPTION

       FMRI  stands  for  Fault  Management  Resource  Identifier.  It is used to identify resources managed by the Fault Manager. See fmd(1M) and
       smf(5).

       The in.daytimed service provides the server-side of the daytime protocol. This protocol is used for debugging and bandwidth measurement and
       is available on both TCP and UDP transports, through port 13.

       The  in.daytimed  service  is  an inetd(1M) smf(5) delegated service. The in.daytimed detects which transport is requested by examining the
       socket it is passed by the inetd daemon.

       TCP-based service

	   Once a connection is established, the in.daytimed generates the current date and time in ctime(3C) format as 7-bit ASCII and  sends	it
	   through the connection. The server then closes the connection. Any data received from the client side of the connection is discarded.

       UDP-based service

	   The	in.daytimed  listens  for  UDP datagrams. When a datagram is received, the server generates the current date and time in ctime(3C)
	   format as 7-bit ASCII and inserts it in a UDP datagram sent in response to the client's request. Any received data is ignored.
