i want to know why does ping sometimes freezes\hangs?
as like this, when u ping node1 it pings lol!
u wait some time and ping it again, it doesnt
assuming wired connection over a switch and firewalls are down.
i just want to know the actual reason,or any clue to the reason.
i googled for days over internet and found nothing useful, so i thought u guys
might help me on this.
I am not seeing that problem here.
It’s always possible that the node you are pinging is ignoring the pings.
thank u for replying but i want to know why that happens?and how can i stop it?
there are a situations where ignoring the ping is not an option,
im running parallel program over these nodes, and if one of these nodes ignored
the ping, the whole process will freeze then it will need to be shutdown manually

Get a LAN trace from both sides to see if the packet is making it. When
it is, troubleshoot why it isn’t returned. When it isn’t, troubleshoot
the routing/network in between. I’ve seen switches do this when they were
dying (some terrible white Netgear gigabit switches had this problem…
pieces of junk, completely unreliable in weird ways once they started to die).
