Nmap for Windows works great...You can access the command line with it but, as with most to-Windows ports with GUIs, the GUI builds the command line for you which is great for beginners. It also shows you the command line it will run once you select the scanning options you want through the tabbed windows, so you can start to learn what the arguments do even before knowing they exist.
The helpfile/documention is really easy to understand if you're new to this kind of stuff. And the really technical stuff you probably won't need to worry about yet... -- Chris Wanstrath : [EMAIL PROTECTED] LW Consulting : www.lw-consulting.net -----Original Message----- From: Bradley Adams [mailto:[EMAIL PROTECTED] Sent: Thursday, August 07, 2003 5:00 PM To: [EMAIL PROTECTED] Subject: Re: verifying an open or closed port on an ip address In-Reply-To: <[EMAIL PROTECTED]> A great tool that I use for this type of "information gathering" is NMAP. Go to http://www.insecure.org It does a lot more than what you want however it has a simple command that you can use to see if a single port is open on an IP address and you can use other types of "pings" other than ICMP such as ACK and SYN. check it out. There is a windows version available however I don't know if it does command line. You can always install cygwin and emulate a unix/linux box on your windows box... go to http://www.cygwin.com then you can use the cygwin unix emulation command line version of NMAP. l8tr Bradley Adams [EMAIL PROTECTED] "You will hardly know who I am or what I mean" "Linux...
