This guide is the second in a 3 part series. Part 1 covers the Installation of Nessus 4 on the Jaunty Jackalope - Ubuntu 9.04. Part 2 is the installation of OpenVas 2 on Ubuntu 9.04 and Part 3 will be a show down between the two vulnerability scanners. A full review with comparison scan results from a number of sample systems. Nessus is a commercial product from Tenable while OpenVas is an open source product that branched from the original Nessus open source project releasing version 1.0 in August 2008.
This guide will cover the installation of the following OpenVas components on Ubuntu 9.04 (Jaunty Jackalope). While specific to 64bit, other versions of Ubuntu should have no trouble with the following steps.
apt-get install build-essential libgtk2.0-dev libglib2.0-dev libssl-dev htmldoc libgnutls-dev libpcap0.8-dev bison libgpgme11-dev libsmbclient-dev snmp pnscan wget http://wald.intevation.org/frs/download.php/595/openvas-client-2.0.4.tar.gz wget http://wald.intevation.org/frs/download.php/561/openvas-libnasl-2.0.1.tar.gz wget http://wald.intevation.org/frs/download.php/600/openvas-libraries-2.0.3.tar.gz wget http://wald.intevation.org/frs/download.php/607/openvas-manager-0.6.1.tar.gz wget http://wald.intevation.org/frs/download.php/588/openvas-plugins-1.0.7.tar.gz wget http://wald.intevation.org/frs/download.php/593/openvas-server-2.0.2.tar.gz
As stated in the docs, the components you have downloaded should now be installed in the following order:
tar zxvf openvas-libraries-2.0.3.tar.gz cd openvas-libraries-2.0.3 ./configure make make install openvas-libraries has been sucessfully installed. Make sure that /usr/local/bin is in your PATH before you continue Be sure to add /usr/local/lib in /etc/ld.so.conf and type 'ldconfig' Ubuntu is already good to go with these so move onto the libnasltar zxvf openvas-libnasl-2.0.1.tar.gz cd openvas-libnasl-2.0.1 ./configure make make install tar zxvf openvas-server-2.0.2.tar.gz cd openvas-server-2.0.2 ./configure make make install tar zxvf openvas-plugins-1.0.7.tar.gz cd openvas-plugins-1.0.7 ./configure make make install tar zxvf openvas-client-2.0.4.tar.gz cd openvas-client-2.0.4 ./configure make make install
Create an SSL certificate for the openvas server:
Create a user account on the openvas server:
Update your plugins:
Start the server:
Running from a server (no gui) works well and thats how we do it here at (HT). To run a scan you need to create a text file with your target IP's or ranges.
echo "192.168.1.100" >> iptoscan.txt OpenVAS-Client --help Usage: OpenVAS-Client [OPTION...] - client for the OpenVAS security scanner Help Options: -?, --help Show help options --help-all Show all help options --help-gtk Show GTK+ Options Application Options: -v, --version Display version information -n, --no-pixmap No pixmaps -q, --batch-mode=

Well the server is not listening here so a quick check to find the port its on:
netstat -nap | grep openvas tcp 0 0 0.0.0.0:9390 0.0.0.0:* LISTEN 11265/openvasd: wai
Listening on 9390 so change the client line to the correct port!
OpenVAS-Client -q 127.0.0.1 9390 admin password iptoscan.txt scanresults.html -T html
Accept the certificate when prompted.
Once the scan is completed take a look at scanresults.html for your complete report.
There are many benefits to running the OpenVas Client from a command line, you can easily schedule tasks and script using simple bash much of your vulnerability assessment requirements. Run a scan against your servers each week or each month and quickly pickup any new services and vulnerabilities.
If you wish to use the GUI client, check your gnome menu's you should have a new program. Not too difficult from there to work out the client.
