BanHammer: Fail2Ban Monitor

BanHammer connects directly to your Linux server and shows you — in real time — who is trying to break in and who has already been blocked by Fail2Ban. • Live ban feed — watch new bans appear the moment they happen via WebSocket • Jail overview — ssh, postfix, dovecot, and every other Fail2Ban jail at a glance • World map — see blocked IPs plotted on an interactive globe with animated arc lines • Statistics — top attackers by IP and country, trend charts, attack heatmap • Manual unban & whitelist — unban IPs or whitelist them directly from the app • Local notifications — get alerted when attack waves hit, repeat offenders appear, or your server goes offline • Multiple servers — manage all your servers in one place • Home Screen widgets — ban count and server status without opening the app • iCloud sync — your server configurations survive app reinstalls (opt-in) REQUIREMENTS BanHammer requires the free, open-source banhammer-agent to be installed on your Linux server. The agent parses Fail2Ban logs in real time, stores events in a local SQLite database, and exposes a REST API + WebSocket endpoint. Setup takes about 5 minutes. → github.com/a6k/banhammer-agent YOUR DATA STAYS ON YOUR SERVER BanHammer connects directly from your device to your server — no cloud backend, no analytics, no third-party services. Your API key is stored in the device Keychain. Nothing leaves your infrastructure except the connection to your own server. PERFECT FOR Self-hosters, homelab operators, and sysadmins who want a native, beautiful iOS/macOS interface for their existing Fail2Ban setup — without SSH.
