A simple xinetd configuration to enable the echo service can easily be made.
Just create the following file before restarting xinetd:

/etc/xinetd.d/echo:

# description: An echo server.
service echo
{
        type            = INTERNAL
        id              = echo-stream
        socket_type     = stream
        protocol        = tcp
        user            = root
        wait            = no
        disable         = no
}


Or if you are using inetd, before restarting, add
this line to your /etc/inetd.conf:

echo   stream  tcp     nowait  root    internal
