Bannerhunter

Bannerhunter is a powerful banner grabbing tool written in C. It can connect to services running on different ports, attempt plain TCP grabs, and also perform SSL/TLS handshakes for encrypted services. The tool sends protocol-appropriate requests (like HEAD with Host headers for HTTP/HTTPS) to increase the chance of extracting banners.

Features

• Works on both Linux(Debian,RedHat,Arch) and Termux

• Supports plain TCP and SSL/TLS connections

• Sends proper Host headers for HTTP/HTTPS

• Can attempt banner grabs across multiple ports (HTTP, HTTPS, FTP, SSH, SMTP, and custom services).

• Receive timeout handling to prevent hangs when services don’t respond

• Installer and uninstaller scripts for easy setup and removal
