adsb-exchange VS endlessh

Nice photo! Don’t pay attention to some of the overzealous skeptics. If your friend can provide time/place, you can double check https://www.adsbexchange.com/ to see if there were any planes.

Next time you see a weird craft in the air go this this website: https://www.adsbexchange.com/

If so, might I recommend ADSB Exchange?

Here are 2 tracking sites www.flightradar24.com www.adsbexchange.com

About anything you can see in the sky from Fairfax would be in ADS-B Out required airspace. You can look at a live map at https://www.adsbexchange.com/ or https://flightaware.com/

FlightRadar24 and FlightAware have been known to censor police and military aircraft. You might want to try ADS-B Exchange. I haven’t verified if the local police aircraft show up there or not.

You can reduce the noise a lot by moving ssh to a non standard port. Security through obscurity isn't actually security, but it will reduce the number of attempts you receive. Another thing I like to do is put Endlessh on the standard port 22. That way as bots go by they will get stuck or at least slow down on that connection.

SSH tarpit with Endlessh and for the hidden SSH: auth with both a key files (that need unlocking and is on the computer) AND an One Time Password on my phone.

If you change the ssh port, install https://github.com/skeeto/endlessh to slow down the attackers

Even this requires you to successfully guess the username and password correctly, and if it's just not the default most people won't bother brute forcing further. Sidenote: you can use endlessh on a computer and port forward port 22 to trap scanners that scan the entire internet for open ssh ports to exploit.

The fun way is moving your ssh port somewhere else and installing endlessh to f the bots.

Such as endlessh

But, as a prank to Chinese hackers, what I did on my system was to run endless ssh. It keeps the ssh client busy as it slowly sends the ssh banner. I modified the code to send strings like:

For hardening: I use lynis for some guidance, the VPS runs rkhunter, AIDE and other things nightly and mails me the reports, fail2ban manages the SSH port, having SSH on a custom port helps to keep things quiet. If you're into these kind of things, have a look at the Endlessh tarpit to learn about login attempts on port 22 on your machine - I found it eye-opening.
