It allows to easilly manipulate nmap scan results and will be a perfect tool for systems administrators who want to automatize scanning task and reports.

If youre not sure which to choose, learn more about installing packages.

If you need a good network mapping tool but arent a fan of the terminal, check out Zenmap.

Its a GUI front-end for Nmap that has the same features but packed into a slick interface.

From there, elevate the terminal to Root with su or sudo -s.

Luckily, the V command-line switch can display even more information (open ports, etc.).

To do it, write out the command youd be using for a single target but add on other addresses at the end of the command.

For example, to check what two separate targets operating systems are, youd do.

Still, if you have a whole lot of computers or network devices to look at, its smarter to do an IP-range scan with Nmap.

For example, to scan a local network running on the 192.168.1 range, try the following example.

An alternative to scanning a range is to scan all devices in a Subnet.

To do this, enter the base IP of your router (or whatever you use to deliver a network connection to every computer on the network) and use the 24 notation.

However, those arent the only starting IP addresses that exist.

If you need to scan devices on a Subnet and dont use these base IPs, try the following example.
