Suricata+PF_RING安裝詳解

1. 前言

1. Suricata的安裝包可以從 github上克隆安裝，可以從Suricata官網進行下載。本文的測試以github上的版本爲例。
2. 本文的測試平臺爲 CentOS release 6.7 (Final),不同Linux平臺類似。
3. 由於實際需求，本文中的Suricata編譯將加入PF_RING零拷貝工具。

2. 安裝依賴項

$ sudo yum install wget libpcap-devel libnet-devel pcre-devel gcc-c++ automake autoconf libtool make libyaml-devel zlib-devel file-devel jansson-devel nss-devel

安裝過程中，若出現類似 No package *** available.,則自行wget相應安裝包進行安裝。
例如：筆者缺少libnet-devel和jansson-devel ，可以到sourceforge或github進行查找安裝。

3. 檢查配置(configure)

git clone  https://github.com/inliniac/suricata.git
cd suricata
sh autogen.sh
./configure --sysconfdir=/etc --localstatedir=/var 

若需加入PF_RING支持，則添加

--enable-pfring --with-libpfring-includes=/usr/local/pfring/include --with-libpfring-libraries=/usr/local/pfring/lib

類似地，要加入PCRE-jit支持，則添加

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

綜上筆者使用的編譯命令：

./configure --sysconfdir=/etc --localstatedir=/var --enable-pfring --with-libpfring-includes=/usr/local/pfring/include --with-libpfring-libraries=/usr/local/pfring/lib

3. 編譯及安裝

make
sudo make install
sudo ldconfig

4. 配置及規則集安裝

1. Suricata源代碼隨帶默認的配置文件，使用命令sudo make install-conf，可進行安裝。

2. 正如你所知，要是沒有IDS規則集，Suricata毫無用處。頗爲方便的是，Makefile隨帶IDS規則安裝選項。想安裝IDS規則，運行下面這個命令即可。
   sudo make install-rules
   上述規則安裝命令會從EmergingThreats.net(https://www.bro.org)安裝可用的社區規則集的最新快照，並將它們存儲在/etc/suricata/rules下。

5. 測試

5.1 離線檢測

suricata -c /etc/suricata/suricata.yaml -r 0.pcap -l .

5.2 在線檢測
