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 made 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.
