Installing Sagan - Snorby/snorby GitHub Wiki

Quick Note: The latest install instructions can always be found here: https://wiki.quadrantsec.com/bin/view/Main/SaganInstall

Use apt to download libpcre (required by Sagan) and dumbnet (required for unified2 logging, so required for use with Snorby).

apt-get install libpcre3-dev libpcre3 libdumbnet1 libdumbnet-dev

Depending upon if you're using mysql or postgres, you'll run sudo apt-get install libmysqlclient15-dev or sudo apt-get install postgresql-server-dev-8.4, respectively.

The Sagan team suggests using liblognorm. While they state it's available for Debian through apt, the suggested method is using git.

If you decide to install this, you'll need to run the following command for the command snippet that follows in this section:

sudo apt-get install autoconf

Here's from the liblognorm website (https://wiki.quadrantsec.com/bin/view/Main/LibLogNorm, which was taken from http://www.liblognorm.com/help/first-steps-using-liblognorm/):

In order to install from the 'git' resource, open a terminal and enter these commands in this order:

git clone git://git.adiscon.com/git/libestr.git
cd libestr
autoreconf -vfi
./configure --libdir=/usr/lib --includedir=/usr/include
make
sudo make install
cd .. 
# Now one to libee
git clone git://git.adiscon.com/git/libee.git
cd libee
autoreconf -vfi
./configure --libdir=/usr/lib --includedir=/usr/include
make
sudo make install
cd ..
# Now on to liblognorm
git clone git://git.adiscon.com/git/liblognorm.git
cd liblognorm
autoreconf -vfi
./configure --libdir=/usr/lib --includedir=/usr/include
make
sudo make install

Download the latest from http://sagan.softwink.com/download/ (this should be http://sagan.softwink.com/download/sagan-current.tar.gz).

Run

tar -zxvf sagan-current.tar.gz && cd sagan-0.2.0/

Sagan tries to compile with all options. Snorby supports emailing and I don't see the point in doubling up email, so we'll use the --disable-esmtp flag. For the moment, we're not using Prelude, so we'll disable it with the --disable-prelude flag.

If you're using mysql for the database, type:

./configure --disable-esmtp --disable-postgresql --disable-prelude && make && sudo make install

If you're using postgres for the database, type:

./configure --disable-esmtp --disable-mysql --disable-prelude && make && sudo make install

If you're using the preferred barnyard2 method, locate Sagan's configuration file( should be located at /usr/local/etc/sagan.conf). Find the line that says

output unified2: filename sagan.u2, limit 128

and uncomment it.

If you did not decide to use barnyard2, use the same Sagan config file and use the following lines with your own information:

sagan_hostname sagan
sagan_interface syslog
sagan_filter none
sagan_detail 1

output database: log, mysql, user=sagan password=secret dbname=snorby host=localhost
