FastNetMon Community Docker install

For Advanced version, please use this guide instead.

NB! It’s community contributed code and we do not have any guarantees about images content

You can run docker from pre-built image:

docker pull robertoberto/fastnetmon

First, get fastnetmon.conf from github, edit it after download.

wget https://raw.githubusercontent.com/pavel-odintsov/fastnetmon/master/src/fastnetmon.conf -O /etc/fastnetmon.conf

Now create networks.list. Include all your networks CIDR

echo -e "10.10.0.0/20\n10.200.0.0/19" > /etc/networks.list

Add your whitelist networks:

echo "10.240.0.0/24" > /etc/networks_whitelist

Now create log files to access them outside container

touch /var/log/fastnetmon.log
chmod 0644 /var/log/fastnetmon.log

mkdir /var/log/fastnetmon_attacks
chmod 0700 /var/log/fastnetmon_attacks

Downloading image

docker pull robertoberto/fastnetmon

You can run docker manually to test it, or run from a screen.

In this case we’re mapping IPFIX to container. Replace IPFIX1 and IPFIX2 with your local network interface ip which listen to IPFIX from your routers. You can use only one IPFIX interface or more.

docker run -a stdin -a stdout -i \
-v /var/log/fastnetmon_attacks:/var/log/fastnetmon_attacks \
-v /var/log/fastnetmon.log:/var/log/fastnetmon.log \
-v /etc/networks_list:/etc/networks_list \
-v /etc/networks_whitelist:/etc/networks_whitelist \
-v /etc/fastnetmon.conf:/etc/fastnetmon.conf \
-p IPFIX1:2055:2055/udp \
-p IPFIX2:2055:2055/udp \
-t robertoberto/fastnetmon /bin/bash

Now you’re inside container. Run

fastnetmon &
fastnetmon_client

Also you can build your own image using Dockerfile at packages/docker

cd src
docker build .

To send email, we recommend you to use a external and linked postfix container such:

docker pull panubo/postfix
docker run \
-e MAILNAME="example.com" \
-e MYNETWORKS="127.0.0.0/8, 172.16.0.0/12" \
--name postfix \
-t panubo/postfix

When you link another container with docker other container name will be added to /etc/hosts pointing to its internal IP. So you can use python script notify, instead of bash one.

Just change MAIL_HOSTNAME=”localhost” to MAIL_HOSTNAME=”postfix” if you start fastnetmon docker container with –link postfix:postfix and create another docker instance with panubo/postfix as –name postfix, for example.

A full example of running fastnetmon linked to postfix:

docker run -a stdin -a stdout -i \
-v /var/log/fastnetmon_attacks:/var/log/fastnetmon_attacks \
-v /var/log/fastnetmon.log:/var/log/fastnetmon.log \
-v /etc/networks_list:/etc/networks_list \
-v /etc/fastnetmon.conf:/etc/fastnetmon.conf \
-v /etc/networks_whitelist:/etc/networks_whitelist \
-v /usr/local/fastnetmon:/usr/local/fastnetmon \
-v /etc/exabgp_blackhole.conf:/etc/exabgp_blackhole.conf \
-v /var/log/fastnetmon-notify.log:/var/log/fastnetmon-notify.log \
-p 10.100.20.2:2055:2055/udp \
-p 10.100.20.6:2055:2055/udp \
-p 10.100.20.2:179:179/tcp \
--name fastnetmon \
--link postfix:postfix \
-t robertoberto/fastnetmon:latest /bin/bash

First, you need to create all those files and dirs in main Linux system.

mkdir /usr/local/fastnetmon
touch /var/log/fastnetmon_attacks /var/log/fastnetmon.log /etc/networks_list /etc/networks_whitelist /etc/fastnetmon.conf /etc/exabgp_blackhole.conf/var/log/fastnetmon-notify.log

cp /etc/fastnetmon.conf /etc/fastnetmon.conf.bkp
cp /usr/local/fastnetmon/fastnetmon_notify.py /usr/local/fastnetmon/fastnetmon_notify.py.bkpwget https://raw.githubusercontent.com/pavel-odintsov/fastnetmon/master/src/scripts/fastnetmon_notify.py -O /usr/local/fastnetmon/fastnetmon_notify.py 

chmod +x /usr/local/fastnetmon/fastnetmon_notify.py 
wget https://raw.githubusercontent.com/pavel-odintsov/fastnetmon/master/src/fastnetmon.conf -O /etc/fastnetmon.conf
