## Introduction

Zenmap was designed to accomodate and run more than one scan at time. Each scan is executed and shown inside a Scan Tab, which has a title and organize every information obtained in the scan result.

The Scan Tab tries to facilitate your life, by making the informations easier to navigate and search for a given information. Usually, if you wanted to scan an entire network using Nmap, you would have to open up your favorite terminal, type an entire Nmap command, like this one: nmap -A -F -n -T4 192.168.1.1-254 and when it finally finishes you'll end up with a bunch of lines in the terminal that can hardly be searched and read. If your goal was to know which of the 200 hosts found are serving ssh, what were you going to do? Maybe it won't seen impossible for you, (and it's not) but surely it's a boring task that gets worst when you have to do that more than once.

An answer to your problem is Zenmap, that can handle this task easily, with just a couple of clicks.

So, if you're wondering if you should retire the command line, I would say NO!. The Nmap's command interface is very usefull when you want to scan a few hosts, and skim the result quickly to make a decision. Every good network administrator know how usefull is it to simply call nmap localhost to know which services are up, for example. If you're at the command line, you won't want to open a graphical application to do so, if you can quickly pull off your doubt about what is up or down from were you stand.

Zenmap is intended to help you manage your network, by giving you a better way to examine carefully your network peers. If your intention is to know better your network, then Zenmap is what you need.

## Starting a scan

To start a scan, you need an empty Scan Tab. At the time you starts Zenmap, a new Scan Tab is made available, and as soon as the main interface is shown, you can start typing the target address. If you already used this Scan Tab, you can create a new one, by doing one of the following:

Procedure 1. Use the key-stroke

- The key-stroke that creates a new Scan Tab is CTRL + T.

Procedure 2. Single click on the Create new Scan Tab button Icon in the Main Toolbar

- The Create new Scan Tab button is the 1st button in the Main Toolbar from left to right.

Procedure 3. Acces from the Main Menu

- Go to the Main Menu (the one on the top of the application), File->New Scan.

## Setting a Target

By the moment you start Zenmap or create a new scan tab, you can start typing the address of the target(s) that you want to scan. Every target inserted into the Target field is recorded and remembered in case you need it in the future. As this field features an auto-completation, it's going to be easy the reuse of targets.
