Port Scan

All -
Is it possible to ping a specific port within the windows 2000 command line "ping"
command? I'm not sure that there is, and if that is the case, is anyone aware of
an Nmap type program that is compatable with W2K?
Thanks,
Stu

Open a DOS window and type the following without quotes: "ping /?" This will
list available switches.

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.

Pinging by default with Win2K cmd line is bound to ICMP packets. These are different
than TCP or UDP packets, so they can be controlled differently. Sometimes systems
are set to reject all ICMP ping packets, but are left wide open to TCP and UDP pings.
ping -v TCP (or udp if you prefer) IP. However, I do not believe a ping can be
directed at a specific port from a cmd prompt in Win2k.
