If you run some sort of shell server, or where many people need to login using ssh, you'll have a bit of a support problem telling people to select the non-default port. Also, some might consider it security through obscurity, which is often said to be a bad thing. -- Bruce Cran _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org" I agree. I run ssh on a different port and still some hackers, usually from the Far East still detect it and try to gain access. It happens all the time. Remember there is a big difference between a break-in and an attempted break-in. It is a sad state of affairs that so much effort and energy and high IQ thinking is spent on security these days. If we could just channel all that energy into something more useful. The point about giving so many others ssh logins is something I cringe on as well. I realize it's useful and needed, but there is a real myth out there that hackers are overwhelmingly intelligent and must be highly skilled to hack into someone's system. I think if you were to examine the real numbers you'd find the vast majority of break ins come from someone who either has a login username and password, bought or stole a username and password or overheard someone talking about their username and password. There are of course exceptions but the media and hype about all these intelligent hackers is just overblown. Loose lips sink ships. And as soon as more than one person knows a secret...it's no longer a secret. _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org" ---------------------------------------------------------------------------- --------------'¨ Thanks all for responding and contributing to my post. For the moment, "all quiet on the eastern front" I followed the advices I got, changed the ssh port, and it drastically reduced the noise in my log files. My guess, it was some kind of "bots" probing. Lots of resources down the drain. It really would be nice to set up some kind of "tarpit" to slow down them suckers a bit. I have a faint memory of seeing some suggestions of doing that with a "que" rule or something in PF. Have to "google" a bit and look into it. The good thing, it made me scrutinize my security settings and fix things I should have fixed long time ago. As said before, this server is running just for pleasure and educational purposes, so I'm free to do any Changes or experiments I please to. All the best Hasse _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
