I thought it was okay to publicly share the public part of asymmetric key-pairs (as in SSH and PGP keys). But recently I heard that we should protect public keys.
Is it safe to publicly share public part of our asymmetric key pairs?

Claramente no todo se puede hacer con #SSH 😜

Acá probando "sudo sshd -t" para verificar la sintaxis del archivo de configuración del servidor.

Se viene nuevo contenido en #JuncoTIC, se nota? 😉

One clever method to deal with #ssh #bruteforce #bots is to first allow the connection and then sever it abruptly without a proper close. No FIN, no RST.

The bot will just sit there thinking it is still connected while you are actually not spending any resources at all.

Collective defense by means of the attacker's time being wasted!

Here is a neat project visualizing this on a globe:

Once there was https://blog.stribik.technology/2015/01/04/secure-secure-shell.html, which was fine. Now there is https://infosec.mozilla.org/guidelines/openssh, which doesn't include a date of the last update* (except perhaps the copyright 2017).

Where can I find current recommended SSH settings, with post-quantum and stuff?

* Oh, how I loathe websites that don't add the dates of creation and/or last update!

At a conference I was working from an #iPad and quickly realized I needed a proper terminal client. Echo is a solid #SSH and #Mosh app. It also feels genuinely native, with good keyboard support and a clean, practical UI: https://replay.software/echo

How to SSH into your Kobo ereader and android phone

I had a big post about why I was doing this part written, I felt silly and nuked it, and then I realised that somebody else might want to do one of these things, so I should share how I ended up doing it. My motivation: be able to sync files from two closed-source devices I own over ssh for ease. Kobo eReader It’s a good little device and unlocking ssh was pretty easy.

Since #juiceSSH seems to have become abandonware, what #SSH client would people recommend for #android?

Bonus points if there's some way to export/import configs.

Why do I find #SSH authentication keys so difficult to implement?

The closest I have found to an idiot's guide didn't work and now I have messed with so many config files I will probably have to do a fresh install to have a chance.

Does anyone know of a really simple walk-through *which is not a YouTube video* and not about GitHub? Ideally for a #RaspberryPi 5 but Debian will do.
