Re: [OT] SSH throttle - security
I have an ssh annoyance - my logs are FULL of cracking attempts. This is
an externally visible server, so I can't simply shut off access. They are
trying lots of random accounts, and I'm not worried that they'll get in,
but it's a pain, both because it generates huge logfiles, and also
because it burns non-trivial CPU.
Does anyone know of an option/method to "throttle" incoming SSH requests.
I would be more than happy to limit said requests to one every N seonds,
where N is in the range of 5-10 (or more?)
This doesn't throttle (which might possibly lock you and other legitimate
users out), but it does block failed attempts and attempts to log in as
nonexistent users (particularly root):
I've used this on Mac OS X systems, but I'm sure it's easily adaptable to
