If you have an open stream, pass PING messages and send PONG replies. That will discover your round-trip time, and you can notice timeouts. Or, if you don't have an open socket, open one. That's what the perl ping module does for non-root processes, it opens a short-lived socket. -- greg _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
