Installation from GIT with PCRE-JIT

In this guide will be explained how to install and use the most recent code of
Suricata on Ubuntu together with PCRE with JIT 8.20-RC1 support. The goal of
PCRE-JIT is to improve the pcre pattern matching performance of the pcre
library.
The easiest way to see performance difference is to create a couple of pcre
only rules or use for example the SSN rules from ET, and compare the
performance statistics for rules.
Installing from GIT on other operating systems is basically the same, except
that some commands are Ubuntu-specific (like sudo and apt-get). In case you are
using another operating system, you should replace those commands by your
operating-specific commands.

Pre-installation requirements

Before you can build Suricata with PCRE-JIT for your system, run the following
command to ensure that you have everything you need for the installation.

  sudo apt-get -y install build-essential autoconf automake \
  libtool libpcap-dev libnet1-dev libyaml-0-2 libyaml-dev \
  zlib1g zlib1g-dev libcap-ng-dev libcap-ng0 \
  make g++
  sudo apt-get install git-core

Depending on the current status of your system, it may take a while to complete
this process.

PCRE with JIT support

Enter the following commands for PCRE JIT installation:

  wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/Testing/pcre-8.20-
  RC1.tar.gz
  tar -xzvf pcre-8.20-RC1.tar.gz
  cd pcre-8.20-RC1
  ./configure --enable-jit

Make sure you see that JIT compiling support is enabled, see example:

  make
  sudo make install



HTP


HTP is bundled with Suricata and installed automatically. If you need to
install HTP manually for other reasons, instructions can be found at HTP
library_installation.


IPS


By default, Suricata works as an IDS. If you want to use it as a IDS and IPS
program, enter:

  sudo apt-get -y install libnetfilter-queue-dev libnetfilter-queue1
  libnfnetlink-dev libnfnetlink0


Suricata

First, it is convenient to create a directory for Suricata. Name it 'suricata'
for example. Open the terminal and enter:

  mkdir suricata

Followed by:

  cd suricata

Next, enter the following line in the terminal:

  git clone git://phalanx.openinfosecfoundation.org/oisf.git
  cd oisf

Followed by:

  ./autogen.sh


Compile and install

To configure, please enter:

  ./configure --enable-pcre-jit \
  --with-libpcre-includes=/usr/local/include \
  --with-libpcre-libraries=/usr/local/lib

After entering the previous, make sure that your screen looks like the
following example and you have PCRE with JIT support:

  make
  sudo make install

  sudo ldconfig

To check the build information you can enter:

  suricata --build-info

Please continue with Basic_Setup.
In case you have already made a map for the most recent code, downloaded the
code into that map, and want to download recent code again, please enter:

  cd suricata/oisf

next, enter:

  git pull

After that, you start again at running autogen.
