Why so many bots?
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.

Is SSH secure enough?
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.

"Failed password for root" SSH login hacking attemp?
If you change the ssh port, install https://github.com/skeeto/endlessh to slow down the attackers
-
ChatGPT doxes itself
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.

Ssh brute force attack with fail2ban.
The fun way is moving your ssh port somewhere else and installing endlessh to f the bots.

Keep it tight everyone! This is a day of sshd logs from a proxy server in China pinging my SSH server and trying every username imaginable. Does anyone have any tips to increase security?
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:
-
VPN to remotely access dockerized services
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.

Create a subghz file from known data?
For example, rtl_433 has the spec for an X10 sensor say I know what data I want to put where, is there some tool/site I could enter in what the "specifications" of the signal waveform are and the data I want to send as a byte-string or binary-string and it would create a playable .sub file for me?

New Guy: Outdoor Thermostat / automated fan start/stop.
For "outdoor distances" I'd probably stick to something LoRa or 433MHz based. YoLink has quite a few options using the LoRa protocol. I use basic 433Mhz based AcuRite sensors paired with an RTL-SDR dongle connected to a machine running RTL_433, and use Home Assistant to trigger automations and alerts.

Mystery signal?
866-868MHz is SRD/ISM band (in UK/EU). Can be things like energy meters, TPMS, medical devices etc. Try rtl_433 on it.

Problem trying to listen to a Honeywell doorbell (RF 868 Mhz) with RTL-433
I'm trying to add a Honeywell doorbell to Home Assistant by using the RTL-433 GitHub project/program. When I run the program the SDR dongle is detected but it doesn't display anything when I press the doorbell (the image shows what I see after running the program and pressing the doorbell). I have also tried Honeywell Activelink (FSK) aka [116], so I have tried both 115 and 116 decode protocols.
