Endlessh

Uses a single-threaded C program with poll() to handle multiple clients efficiently, keeping system overhead low as described in the README's design philosophy.

Operates before SSH cryptographic exchange, eliminating the need for cryptographic libraries and reducing complexity, as highlighted in the key features.

Allows tuning of delay, line length, client limits, and logging via command-line or config file, with examples provided in the README for adaptability.

Supports signals like SIGTERM for clean shutdown, SIGHUP for config reload, and SIGUSR1 for connection stats, ensuring easy management as detailed in the usage section.
