Fail2ban

Fail2ban is a tool that reads server logs and asks the firewall to block addresses that behave like attackers. This tag collects guides about keeping RSS and Atom feeds reachable when fail2ban or similar protection is active. Articles explain how to find wrong bans, exclude the feed path from filters that count requests and errors and log the real visitor address behind a proxy. They also cover bans that grow with repeat offences, testing filters with the regex tool and redirecting old feed paths. The advice helps site owners protect their servers and still share every new article on social networks automatically.
