From 099ac31f8fc39d318d6ba8b03bd85693899673bf Mon Sep 17 00:00:00 2001 From: Feng Pan Date: Mon, 9 May 2016 20:22:52 -0400 Subject: [PATCH] Change ping wait flag This is an optimization of the ping command. It changes ping test from waiting for a single sent packet for 300 seconds to waiting to receive a packet from any number of sent packets. The current implemenation waits for full 300 seconds before retrying if we do not get a reply for the first packet sent. By using -w flag, we keep sending icmp packets until a reply is sent, making the ping test more responsive to connectivity change.
