How to change the output-format of the daytime xinetd service

Solution Verified - Updated -

Environment

  • Red Hat Enterprise Linux 5.5
  • daytime service over xinetd

Issue

Migrating from Tru64 to Red Hat Enterprise Linux 5 requires that the daytime protocol behaves the same on RHEL5 as compared to Tru64. On Tru64 the output of daytime has the following format:

Wed Sep 22 08:51:56 2010

On RHEL5, the format looks like this:

22 SEP 2010 09:34:47 CEST

How can daytime be configured so that RHEL5 gives the same format as Tru64?

Resolution

Create a script that displays the time in the correct format, for example /usr/local/bin/tru64-date:

#!/bin/sh
date +"%a %b %d %T %Y"

After that, change the configuration provided by the xinetd package in /etc/xinetd.d/daytime-stream:

service daytime
{
        disable         = no
        id              = daytime-stream
        type            = UNLISTED
        port            = 13
        user            = root
        wait            = no
        socket_type     = stream
        server          = /usr/local/bin/tru64-date
}

After making these changes, restart the xinetd service:

# service xinetd restart

Check if the output is correct now:

$ telnet localhost 13
