What is vgt-auto-punisher?

VGT Auto-Punisher is a zero-dependency shell script that turns your Linux server into a kernel-level behavioral intrusion detection system. Run it with sudo, whitelist your IP first, pick ports to monitor like SSH or HTTP, and it passively watches SYN packets via logs, auto-banning aggressive IPs or entire /24 subnets after hit thresholds using ipset and iptables. Bans expire in 24 hours via a forgiveness protocol, keeping things reversible without constant babysitting.

Why is it gaining traction?

Unlike Fail2Ban which parses app logs and can lag, this leverages kernel iptables logging for near-zero overhead detection on Linux servers, with a live TUI dashboard showing hits in real-time and color-coded warnings. IPv6 dual-stack support, DPI drops for scan anomalies, and subnet punisher logic nail botnets rotating IPs, all in pure shell with no extras needed. Devs dig the foolproof setup—scan ports automatically, harden TCP with BBR, and persist rules—making auto-punisher a lightweight VGT model on GitHub for instant defense.

Who should use this?

Linux sysadmins securing internet-facing VPS on Hetzner or DigitalOcean, web server operators tired of SSH brute-force noise, or self-hosters with exposed services like Nginx on ports 80/443. Ideal for prod environments needing behavioral punisher without daemon bloat, but skip if you're on containers or prefer managed IDS.

Verdict

Grab it for reactive server hardening—solid README and stable V4.5 claim make testing straightforward, despite 47 stars signaling early maturity. 0.9% credibility score urges caution; whitelist religiously and monitor in staging first.
