Introduction

Open-AudIT uses Nmap in its Discovery function. Without Nmap, Open-AudIT will not function correctly. Every Open-AudIT install assumes Nmap is installed and will test for it on the Discovery web pages.

Linux

The Linux Open-AudIT installer will test for and if required, install Open-AudIT's dependencies from your distributions repository. After installing you should run the below to SetUID. This is required for SNMP (UDP 161) detection. This is supported on RedHat/CentOS and Debian/Ubuntu. If you need to manually install Nmap:

For RedHat/CentOS do (NOTE - if you upgrade using yum, you will need to reapply this "chmod" setting).

sudo yum install nmap
sudo chmod u+s `which nmap`

For Debian/Ubuntu run (including setting dpkg to remember your override so an apt-get upgrade will not break Open-AudIT).

sudo apt-get install nmap
sudo chmod u+s `which nmap`
sudo dpkg-statoverride --list `which nmap`

Windows

The Windows Open-AudIT installer will test for the presence of Nmap in it's standard install locations of:

...

Use the standard install options when displayed and click the "I Agree", "Next" and "Install" buttons to install Nmap. 

Now when you go to a Discovery page, you should not see the below warning.
