NMap 3.55 help

I downloaded NMap 3.55 command line version from www.insecure.org and unzipped the file. My problem is that when i go to open NMap the command line flashes and i dont seem to be able to get it to stay open.

Forgive me if this is a stupid question. :)

How did you start nmap? Did you click something, put it in the "run" window, or did you go through the command line? If either of the former, try the latter, that should do it.

As Angelic has said,
open the cmd line FIRST.
to use anything IN the cmd setting, it always goes better to start it there as well.

LOL i just went to the insecure.org site and found out what i was doing wrong. I had been clicking the icon. I found out that i am supposed to go to the command line and type

"cd C:\nmap-3.55"
"C\nmap-3.55\nmap -A -T4 scanme.insecure.org"

SO my problem is solved lol.

thanks angelic

Yeah, I did the same thing when I first tried it. Starting in the command line with such tools is a good rule of thumb to go by.

Also, I'd reccomend TheHorse13's tutorials on Nmap. That's a great starting point if you need to get acquainted with the program.

Good thing you aren't an idiot as well. NMap also has a relatively outdate UI for people who don't really understand what they are doing. As AK pointed out TH13 wrote a series of very nice tutorials about NMap. I would recommend learning more basic networking and possibly security material as well so you can understand what is going on, or at least the premiss behind some of the stuff.

Yeah, meth's right, not to mention you can do some damage to yourself with that toy if you go at it blindly. Heh heh, and actually I am an idiot as well, which is why I'm here in hopes of de-idiotizing myself. ;) But yeah, make sure you have a good understanding of what that little guy can do to you or someone else before you go crazy with it. TH13 is definately the grand master Jedi with that stuff.

Really...

Care to explain?

Oh must I? Don't I embarass myself around here enough as it is? :D

Ok, well, I was experimenting with if the first time at work one day while reading through TH13's tuts, so I wanted to find a target to scan without ticking anyone off or looking malicious -- So I scanned my home computer from the office. Well, I configured something wrong along the way, and something bounced back as a result of the scan and knocked out our entire Internet connection office-wide (I asked about it a while back right after it happened). So, I had to quickly restart our router and hope no one noticed! That happened TWICE. Yeah, talk about looking like a doofus.

Since then, I haven't touched it, not until I actually know what I'm doing.

If you're on Windows download the 3.50 version. The 3.55 version seems to have a bug that will reboot your system. I noticed this once and today I read this post.

NMAP will crush a SOHO NAT router. Do you have a small office (20 or so) running behind a cable/DSL connection? If so, DON'T try to do an NMAP scan again from behind the router. You'll need to jump on infront of it.

--TH13

You called it TH, SOHO NAT and around 20 or so computers here. Yeah, so I won't mess with that again here. :)

Even after I have typed in "cd C:\nmap-3.55" in Command Prompt it still doesn't work. What do I do?

You have to navigate to the directory it resides in first.

O.k so what do I do then? It's in my D drive, but I've tried changing the command prompt to "cd D:\nmap-3.55" and it still doesn't work.

Sorry for being so ignorant :D

Well, I'm guessing at this point, but try copying it to your hard drive, then run it from whatever directory you stick it in.

nmap is located in:
[glowpurple]D:\Documents and Settings\admin\Desktop\nmap-3.55-win32\nmap-3.55,[/glowpurple]
so what do I type in cmd to start it up?

Thanks

When you start cmd where are you? c:\Documents and Settings\your name.......?

Edit

Just copy Nmap to your system32 folder. It will start without having to navigate to where ever you have put it.

Edit

D:\Documents ans Settings\Tim

Edit

I have copied it in it's folder to system32, and I just went onto cmd but it still can't be found. Do I have bad luck or am I just rubbish at this?!?!

Tim

Yeah, copy it from CD to that folder as you would any other file you would copy.

Thanks for the advice! I'll try again tomorrow.

Hmm good suggestion ill try the 3.50 version instead.
