At first you should install PF_RING (you can install any latest version
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:
cd kernel
make
make install
modprobe pf_ring
You can use precompiled and statically linced version of this tool without any compiling:
mkdir /root/fastnetmon
cd /root/fastnetmon
wget https://raw.githubusercontent.com/FastVPSEestiOu/fastnetmon/master/fastnetmon -Ofastnetmon
chmod +x fastnetmon
./fastnetmon eth0
If you want to use static version you can skip this guide to part about "networks_list".
Build lib (We disabled bpf because it requires linking to PCAP):
# Debian
apt-get install -y libnuma-dev
# CentOS
yum install -y numactl-devel
cd /usr/src/PF_RING-6.0.2/userland/lib
./configure --disable-bpf --prefix=/opt/pf_ring
make
make install
Install FastNetMon:
# 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
Select backend, we use PF_RING as default, if you need PCAP you must change variable ENGINE in Makefile. Compile it:
make
You should start fastnetmon using this options:
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:
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:
cp fastnetmon.conf /etc/fastnetmon.conf
Start it:
./fastnetmon eth1,eth2
