Scanning
| Chapter 12. Zenmap GUI Users' Guide |
## Scanning Begin Zenmap by typing zenmap in a terminal or by clicking the Zenmap icon in the desktop environment. The main window, as shown in Figure 12.2, “Zenmap’s main window”, is displayed. Figure 12.2. Zenmap’s main window One of Zenmap’s goals is to make security scanning easy for beginners and for experts. Running a scan is as simple as typing the target in the “Target” field, selecting the “Intense Scan” profile, and clicking the “Scan” button. This is shown in Figure 12.3, “Target and profile selection” Figure 12.3. Target and profile selection While a scan is running and after it is finished the output of the Nmap command is shown on the screen. Any number of targets, separated by spaces, may be entered in the target field. All the target specifications supported by Nmap are also supported by Zenmap, so things like `192.168.0.0/24` and `10.0.0-5.*` work. The targets scanned most recently are remembered. To re-scan a host, select the host from the combo box attached to the “Target” text field. ### Profiles The “Intense Scan” is just one of several scan profiles that come with Zenmap. Choose a profile by selecting it from the “Profile” combo box. Profiles exist for several common scans. After selecting a profile the Nmap command line associated with it is displayed on the screen. Of course, it is possible to edit these profiles or create new ones. This is covered in the section called “The profile editor” It is also possible to type in an Nmap command and have it executed without using a profile. Just type in the command and press return or click “Scan”. The user interface for specifying a custom scan from a command line is currently a bit touchy. After typing a custom command, be careful not to accidentally select another target or profile because doing so will wipe out the current command. ### Scan tabs More than one scan may be displayed at the same time. It is even possible to have several scans running concurrently. Zenmap gives support for this through its scan tabs. An example of scan tabs showing three scans is shown in Figure 12.4, “Scan tabs” Figure 12.4. Scan tabs To open a new scan tab, choose “New Scan” from under the “Scan” menu or use the ctrl+T keyboard shortcut. To close a scan tab, choose “Close Scan” from the “Scan” menu, type ctrl+W, or click the close icon on the tab itself. You will be prompted to save any unsaved results before closing. To halt a scan in progress, enter new parameters and click the “Scan” button again, or close the scan tab. This unfortunately has the side effect of discarding any output shown in the scan so far.
