#OpenSSH

Wow, #OpenSSH is now warning you if your terminal session might be decrypted by #QuantumComputers in the future.

On the off-chance this technology magically succeeds unlike all the other unfounded hype out there, we will have much bigger problems than people in the future knowing how many times I needed to clear the cache before this damn website would work properly.

, a SOCKS #proxy defines how traffic is handled dynamically, while #OpenSSH port forwarding provides the secure, encrypted tunnel for that traffic. The OpenSSH -D option combines both concepts into a single, secure solution

Nice deep dive into SSH keystroke obfuscation and why packet captures look so noisy. Learned something new here.

I am maintaing this patch for #openssh: github.com/openssh/openssh-por

It's based on another change from Pawel Dawidek and has contributions from others and me, and I use it every day to connect to a VM running in #VMware #Fusion. I find it very useful because it makes connecting to a VM independent from the network.

I gather it's useful for others too, and I think it should be merged into upstream. However it gets no attention whatsoever, and I have no idea what to do about it.

Pünktlich zum habe ich mein erweitert um
.

Ich zeige wie man sich an Servern einloggen kann mittels Device Bound à la , , etc.

Damit liegt der geheime Schlüssel im Passkey-Token und kann nicht ohne weiteres ausgelesen werden.

Außerdem zeige ich noch wie man einen 2. externen OpenSSH-Server nur für die Hardwaretoken konfiguriert.

Viel Spaß am Gerät

Just learned about the existence of #PuttyCAC and that (supposedly) the Putty project rejected implementing OpenSC smartcard support.

So now the only way you can use a smartcard (aka. a yubikey) for SSH authentication with #FileZilla and/or #WinSCP is to use it as both still do NOT support #OpenSSH agent but only the Putty Pageant.

So if anyone else is looking for a way to use their smartcard with WinSCP or FileZilla, install OpenSC, reboot, install Putty-CAC, start Putty-CAC|s pageant.

OpenBSD: It's like the cool kid at the party who just can't stop telling everyone how secure and free it is, but really just wants you to notice its tattoo. 🤔✨ Two remote holes in the default install? Wow, must be a record-breaking snooze fest! 💤🔒

Hoje eu aprendi que, com OpenSSH, basta um mero ssh -D 9999 -N destino — ou com autossh se quiser retomar automaticamente a conexão que cair — para poder usar a porta local (9999 no exemplo) como SOCKS proxy saindo pela máquina destino especificada! :mindBlown:

Vivendo e aprendendo, temos que tirar o chapéu também para o pessoal do #OpenBSD que presenteia o mundo ao desenvolver essa maravilha.

Returning out of necessity to a project I abandoned to stop myself from getting an aneurysm and immediately I find a comment reminding me why I abandoned it in the first place:

OpenSSH is really super GODDAMN PICKY about motherfucking permissions

The entire path, INCLUDING WHEREEVER THE GODDAMN MOUNT IS MOUNTED ALL THE WAY UP TO /

must be owned by root. FUCK!

Thou shalt not provide #OpenSSH authorized_keys in a path of your choosing, that's a crime!

If you used OpenSSH this year you should consider kicking a few bucks over to The OpenBSD Foundation (openbsdfoundation.org/donation)

The few, the proud, the people who donate to open source projects.

Community events like the BSDCons do not have quarterly earnings reports but can sure be at the mercy of them.

If you organization benefits from free software like #BSD Unix and projects Iike #OpenSSH, please make their support a permanent part of your budgets.
