MyDeny Script
by Ramses Soto-Navarro, ramses@sotosystems.com
Overview
The Script
Cronjob
Remove IP
Overview
mydeny.sh script adds IP addresses to /etc/hosts.deny, which have too many bad SSH login attempts. It is a simple alternative to the older python denyhosts. It searches every night for IP addresses that failed to SSH more than 20 times, via cron. If so then it adds it to hosts.deny. Logging of each denied IP will be sent to /var/log/messages as mydeny.sh. Follow the parsing logic to automatically add more libwrap services to hosts.deny. This document is for experienced Linux administrators.
