How should you decide how well ssh tarpitting works? Can you tell if the people who run ssh password guessers have changed their code to account for the presence of endlessh in their target population?

I found the advice from an Enlightened Unix Master about arranging input text for the the venerable troff typesetting system that seems to be ancestral to Semantic Line Breaks.

A not-quite-so-baffling Smurfs™ product from Dollar Tree. Full disclosure: I didn’t buy this, nor have I used it.

You can download the troff source of Brian Kernighan’s UNIX for Beginners - Second Edition from the Plan 9 archive of the 7th Edition Unix documentation. The Plan 9 people re-packaged the various files as bun archives probably sometime in the 1990s, but you can extract the troff input files and run them through GNU groff today, in the 21^st Century.

Three terrible and two good fortunes.

I moved sshd from TCP port 22 to a higher port 2026-08-01T23:31Z. I also put the endlessh tarpit on port 22. sshd has not seen a single password guessing attempt since then. The combination of ssh tarpit, and non-standard port works.

Although I can’t find it on the sum total of human knowledge, the World Wide Web, I have a memory that one of the Enlightened Unix Masters, Dennis Ritchie or Brian Kernighan maybe, wrote some tips about how to format written input for the venerable troff typesetting system.

I stumbled across a blog post about finding the median of a list of numbers as a job interview question.
