CentOS / RHEL: Install nmap Network Security Scanner

To install nmap on CentOS or Red Hat Enterprise Linux (RHEL), you will need to have root privileges or access to a user with sudo privileges.

1. First, update the package repository by running the following command:

sudo yum update

2. Install nmap by running the following command:

sudo yum install nmap

3. Once the installation is complete, you can start using nmap. To check the version of nmap installed, run the following command:

nmap --version

That's it! nmap should now be installed on your CentOS or RHEL system. You can use it to scan networks and hosts to determine their vulnerabilities and find potential security issues.

Note: If you are using CentOS or RHEL version 7 or later, you may need to enable the "Optional" package repository in order to install nmap. To do this, run the following command:

sudo yum-config-manager --enable rhel-7-server-optional-rpms

Then, you can proceed with the installation steps listed above.
