ECHO Protocol

All,
I am checking the ICMP protocol these days and some documents say that Ping command in Windows uses ICMP protocol, while others say that Ping uses ECHO protocol, which is through TCP port 7.
So my question is which protocol is actually used by PING command in Windows?

In ICMP terminology, "echo" is what we normally call "ping". So "uses
ECHO protocol" might just be another way of saying that it uses ICMP. See http://en.wikipedia.org/wiki/Internet_Control_Message_Protocol#List_of_permitted_control_messages_.28incomplete_list.29 & search for "Echo Request" & "Echo Reply". ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Haim (Howard) Roman Computer Center, Jerusalem College of Technology roman@...

I agree with Paul, no real substitute for actual verification ! however this would be ICMP Code 0 Type 8 packet. Thanks, Aditya Govind Mukadam On Mon, Jun 30, 2008 at 6:31 PM, Paul D. Robertson <paul@...> wrote:

The ping command uses ICMP in Windows. Yes, I know that there are alternate "ping" programs that will allow you to use TCP, UDP or possibly anything that programmer could think of, but the traditional ping uses ICMP. Two of the ICMP types are referred to as echo and echo reply, which are the ICMP types used for ping. See the ICMP RFC (http://www.faqs.org/rfcs/rfc792.html) for more detailed information. > > > On 6/30/08, Keith A.
