(synopsis "SSH tarpit that slowly sends an endless banner")
(description
"Endlessh is an SSH tarpit that very slowly sends an endless, random SSH
banner. It keeps SSH clients locked up for hours or even days at a time. The
purpose is to put your real SSH server on another port and then let the script
kiddies get stuck in this tarpit instead of bothering a real server.
Since the tarpit is in the banner before any cryptographic exchange occurs, this
program doesn't depend on any cryptographic libraries. It's a simple,
single-threaded, standalone C program. It uses @code{poll()} to trap multiple
clients at a time.")
