I changed the eth0 MTU size to 1550(using : ifconfig eth0 mtu 1550
) and ran ping -c 1 -M do -s 1500 -w 5 {some other IP}
and
The output I see is,
--- x.x.x.x ping statistics --- 5 packets transmitted, 0 received, 100% packet loss, time 4001ms
The failure here is because Ethernet supports only MTU 1500. Now if run ping -c 1 -M do -s 1472 -w 5 {some other IP}
with the "other IP" host powered off, I get the same output.
How do I find the reason of 0 received, 100% packet loss
? Was it because of MTU issues or that the host was powered off?
