Nessus is a proprietary vulnerability scanner available free of charge for personal use. There are over 40000 plugins covering a large range of both local and remote flaws.


Download and extract the taurball from the AUR:

$ wget
$ tar xvf nessus.tar.gz

Download the rpm from

  • 32-bit: Nessus-4.4.0-fc14.i386.rpm (12103 KB)
  • 64-bit: Nessus-4.4.0-fc14.x86_64.rpm (12092 KB)

Move the rpm into in the nessus directory.

$ cd nessus
$ mv ~/downloads/Nessus-4.4.0-fc14.x86_64.rpm .

Then, make (and install) the package and any needed dependencies:

$ makepkg -csi

Post-installation setup

Create an SSL certificate for the Nessus web interface:

# /opt/nessus/sbin/nessus-mkcert

Register your email at and wait for your key to be emailed to you. Then, download all the plugins from the feed with:

# /opt/nessus/bin/nessus-fetch --register <your key here>

Create a Nessus admin user (unrelated to *nix style users):

# /opt/nessus/sbin/nessus-adduser


Start the daemon just like any other:

# /etc/rc.d/nessus start

You probably don't want to add it to DAEMONS in rc.conf.

Access the web interface at https://localhost:8834 and/or use the commandline interface (/opt/nessus/bin/nessuscmd). In most browsers, you'll need to manually accept the SSL certificate you created for the server.


The package can be removed with pacman, but files created by nessus (such as the plugin database it downloads) must be removed manually:

Note: This will delete your nessus configuration files.
# rm -r /opt/nessus
