How to install nessus on Ubuntu

I might have to explain what Nessus really is first..

Nessus is one of the most famous vulnerabilityscanners, here's an extract from their site:

The Nessus® vulnerability scanner is the world-leader in active scanners,
featuring high-speed discovery, configuration auditing, asset profiling,
sensitive data discovery and vulnerability analysis of your security posture.
Nessus scanners can be distributed throughout an entire enterprise, inside DMZs
and across physically separate networks.



Installation


First, you'll have to download nessus and his plugins

    sudo apt-get install nessusd nessus nessus-plugins

Now we're gonna make nessus run defaultly

    sudo ln -s /etc/init.d/nessusd /etc/rc2.d/S20nessusd

Now we're going to startup nessus

    /etc/init.d/nessusd start

Now we're going to add a user

    sudo nessus-adduser

And to be able to scan any host, you just add "default-accept"


Now we'll restart nessus

    /etc/init.d/nessud restart

and now we startup nessus

    sudo nessus
