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.
