-### All this docs about ExaBGP 4.0 (Git master branch)
+We migrated this page to our [site](https://fastnetmon.com/docs/bgp_flow_spec/)

-Clone code:
-```bash
-cd /usr/src/
-git clone https://github.com/Exa-Networks/exabgp.git
-```
-
-They are not compatible with ExaBGP 3.0

-Run it:
-```bash

-
-Then, please install Git version of FastNetMon (stable version do not support this features yet):
-```bash
-wget https://raw.githubusercontent.com/FastVPSEestiOu/fastnetmon/master/src/fastnetmon_install.pl -Ofastnetmon_install.pl 
-sudo perl fastnetmon_install.pl --use-git-master
-```
-
-FastNetMon configuration /etc/fastnetmon.conf:
-```bash
-# This options are mandatory for Flow Spec attack detector
-collect_attack_pcap_dumps = on
-process_pcap_attack_dumps_with_dpi = on
-
-exabgp = on

-Be aware! We will announce rules with discard option!

-Currently we support only most popular amplification attack types:
-- DNS amplification (we drop all udp traffic originating from 53 port)
-- NTP amplification (we drop all udp traffic originating from 123 port)
-- SSDP amplification (we drop all udp traffic originating from 1900 port)
-- SNMP amplification (we drop all udp traffic originating from 161 port)
