Usage
=====

   netecho is based on the TCP/IP service 'echo' and it's useful to
check the availability of a certain host within scripts. If the given
host is available, the string 'NETECHO' will be printed and the return
value is set to 0 (RETURN_OK). Otherwise an error message is printed
and the return value is set to 20 (RETURN_FAIL).

Usage:
         netecho <hostname>

Example:
         netecho crash.north.de

Example script 1:

         failat 21
         netecho >nil: crash.north.de
         if warn
            echo "crash.north.de is not available!"
         else
            echo "crash is alive! =¦^)"
         endif

Example script 2:

         failat 21
         if "`netecho crash.north.de`" eq "NETECHO"
            echo "crash is alive! =¦^)"
         else
            echo "crash.north.de is not available!"
         endif
