At first you should install PF_RING (you can install any latest version
|
|
|
|
```bash
|
|
cd /usr/src
|
|
wget 'http://downloads.sourceforge.net/project/ntop/PF_RING/PF_RING-6.0.2.tar.gz?r=http%3A%2F%2Fsourceforge.net%2Fprojects%2Fntop%2Ffiles%2FPF_RING%2F&ts=1402307916&use_mirror=cznic' -OPF_RING-6.0.2.tar.gz
|
|
tar -xf PF_RING-6.0.2.tar.gz
|
|
cd PF_RING-6.0.2
|
|
# Debian way
|
|
apt-get install build-essential bison flex linux-headers-$(uname -r) libnuma-dev
|
|
# CentOS
|
|
yum install -y make bison flex kernel-devel gcc gcc-c++
|
|
# CentOS openvz case
|
|
yum install -y make bison flex vzkernel-devel gcc gcc-c++
|
|
```
|
|
|
|
Build PF_RING kernel module:
|
|
```bash
|
|
cd kernel
|
|
make
|
|
make install
|
|
modprobe pf_ring
|
|
```
|
|
|
|
Build lib:
|
|
```bash
|
|
# Debian
|
|
apt-get install -y libnuma-dev
|
|
# CentOS
|
|
yum install -y numactl-devel
|
|
cd /usr/src/PF_RING-6.0.2/userland/lib
|
|
./configure --prefix=/opt/pf_ring
|
|
make
|
|
make install
|
|
```
|
|
|
|
Install FastNetMon:
|
|
|
|
```bash
|
|
# Debian 7 Wheezy
|
|
apt-get install -y git g++ gcc libboost-all-dev make libgpm-dev libncurses5-dev liblog4cpp5-dev libnuma-dev libgeoip-dev libhiredis-dev libpcap-dev
|
|
# CentOS
|
|
yum install -y git make gcc gcc-c++ boost-devel GeoIP-devel log4cpp-devel ncurses-devel glibc-static ncurses-static gpm-static gpm-devel
|
|
|
|
# For compiling on CentOS please remove line "STATIC = -static" from file Makefile and replace line "LIBS += -lboost_thread" by line "LIBS += -lboost_thread-mt"
|
|
|
|
cd /usr/src
|
|
git clone https://github.com/FastVPSEestiOu/fastnetmon.git
|
|
cd fastnetmon/src
|
|
```
|
|
|
|
Build FastNetMon with cmake:
|
|
```bash
|
|
cd /usr/src/fastnetmon/cmake
|
|
mkdir build
|
|
cd build
|
|
cmake ..
|
|
make
|
|
```
|
|
|
|
You should start fastnetmon using this options:
|
|
```bash
|
|
LD_LIBRARY_PATH=/opt/pf_ring/lib/ ./fastnetmon eth3,eth4
|
|
```
|
|
|
|
If you want to avoid LD_LIBRARY_PATH on every call you should add pf_ring path to system:
|
|
```bash
|
|
echo "/opt/pf_ring/lib" > /etc/ld.so.conf.d/pf_ring.conf
|
|
ldconfig -v
|
|
```
|
|
|
|
It's REQUIRED to add all your networks in CIDR form to file /etc/networks_list if form when one subnet on one line. Please aggregate your networks because long networks list will significatly slow down programm. And please change REDIS_SUPPORT = yes to no in Makefile if you do not need traffic counting feature. When you running this software in OpenVZ node you may did not specify networks explicitly, we can read it from file /proc/vz/veip.
|
|
|
|
You can add whitelist subnets in similar form to /etc/networks_whitelist (CIDR masks too).
|
|
|
|
Copy standard config file to /etc:
|
|
```bash
|
|
cp fastnetmon.conf /etc/fastnetmon.conf
|
|
```
|
|
|
|
Start it:
|
|
```bash
|
|
./fastnetmon eth1,eth2
|
|
```
|
|
|
|
Enable programm start on server startup, please add to /etc/rc.local this lines:
|
|
```bash
|
|
screen -S fastnetmon -d -m /root/fastnetmon/fastnetmon
|
|
```
|
|
|
|
When incoming or outgoing attack arrives programm call bash script (when it exists): /usr/local/bin/notify_about_attack.sh two times. First time when threshold exceed (at this step we know IP, direction and power of attack). Second when we collect 100 packets for detailed audit what did happens.
