endless — An SSH
endless is an SSH tarpit that very slowly
sends an endless, random SSH banner.
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:
endlessto use IPv4 addresses only.
endlessto use IPv6 addresses only.
- Message milliseconds delay. Default: 10000
- Set and load config file. By default
endlesslooks for /etc/endlessh/config.
- Print the help message and exit.
-lmax banner length
- Maximum banner line length (3-255). Default: 32
- Maximum number of clients. Default: 4096
- Set the listening port. By default
endlesslistens on port 2222.
- Print diagnostics to syslog. By default
endlessprints them to standard output.
- Print diagnostics. Can be specified up to twice to increase verbosity.
endlessto print version information and exit.
endless receives the SIGTERM signal it
will gracefully shut down the daemon, allowing it to write a complete,
A SIGHUP signal requests a reload of its configuration file.
A SIGUSR1 signal will print connections stats to the log.
