re: Port Scan Thursday, August 16, 2001 at 6:31 am Windows 2000 Annoyances Discussion Forum Posted by B. Hill (1 messages posted) Ping relies on ICMP packets which know nothing about ports. Therefore no "ping" tool (windows, unix, etc.) can "ping ports". You can use an application or a port scanner to test for ports. But remember ports are only reachable at "Layer 4 - Transport Layer" communications involving UDP or TCP. Ping operates only at "Layer 3 - Network Layer" using ICMP (i.e. 'echo request' and 'echo reply' packets). Hope this helps.
