Is ping not enough? An ICMP ECHO REPLY is a specific reply, directed only to the hosts that sent the ICMP ECHO REQUEST in the first place. It's not a prespecified _text_ reply, but it is a reply nonetheless. Of course, if you need more information, you need a client/server implementation. You could e.g. enable 'daytime' in /etc/inetd.conf (and start inetd), if you need the local time of the host, etc... -- Cordula's Web. http://www.cordula.ws/
