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 () jct ac il Phone: 052-8-592-599 (6022 from within Machon Lev) -------- Original Message -------- Subject: [fw-wiz] ECHO Protocol From: peng liu <cleverpigboy () gmail com> To: firewall-wizards () listserv cybertrust com Date: Thu Jun 26 2008 13:00:03 GMT+0300 (IDT)
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?
