This is small guide how to install Fail2Ban which will protect against brute-force attacks to your Asterisk server.
Our script is made by instructions described in this manual.
To install this script execute following commands:
- cd /usr/src/mor/sh_scripts/
- ./upgrade_install_script.sh
- ./fail2ban_install.sh
It will install Fail2Ban and iptables (if they were not present).
You can check log at /var/log/fail2ban.log to see what IPs were blocked.
IP will be blocked if it tries to register to your Asterisk server 5 times without luck.
It will be unbanned after 10 minutes. Most of the times this is enough for attacker to forget about your server and go out to search for other victim.
If you need to install Fail2Ban separately on Centos, use this script: File:Fail2ban install
