ENDLESSH(1) General Commands Manual ENDLESSH(1) NAME endless -- An SSH tarpit SYNOPSIS endless [-46chsvV] [-d delay] [-f config] [-l max banner length] [-m max clients] [-p port] DESCRIPTION endless is an SSH tarpit that very slowly sends an endless, random SSH ban- ner. endless 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 poll() to trap multiple clients at a time. The options are as follows: -4 Forces endless to use IPv4 addresses only. -6 Forces endless to use IPv6 addresses only. -d delay Message milliseconds delay. Default: 10000 -f config Set and load config file. By default endless looks for /usr/lo- cal/etc/endlessh.conf. -h Print the help message and exit. -l max banner length Maximum banner line length (3-255). Default: 32 -m max clients Maximum number of clients. Default: 4096 -p port Set the listening port. By default endless listens on port 2222. -s Print diagnostics to syslog. By default endless prints them to standard output. -v Print diagnostics. Can be specified up to twice to increase ver- bosity. -V Causes endless to print version information and exit. If endless receives the SIGTERM signal it will gracefully shut down the daemon, allowing it to write a complete, consistent log. A SIGHUP signal requests a reload of its configuration file. A SIGUSR1 signal will print connections stats to the log. FILES /usr/local/etc/endlessh.conf The default endless configuration file. FreeBSD ports 15.quarterly January 29, 2020 ENDLESSH(1)
