Released Loadbars 0.13.0, neat tool for monitoring live Linux system resources of remote servers without havig to setup a observability pipeline and/or dashboards. I wrote it in Perl more than 13 years ago, but thanks to AI it's living again, rewritten in Go. https://foo.zone/gemfeed/2026-03-01-loadbars-0.13.0-released.html there are a bunch new features which the Perl version hadn't!

There's a delay when connecting to #systemd based systems with #ssh, it's between "pledge: filesystem" and "client_input_global_request".
It's annoying.
I'm trying to avoid saying fucking.
#sysvinit based #devuan works like a charm.
Не знаю, чому радіють користувачі #Reticulum over #rnsh, якщо вони підключаються в оверлеї через testnet замість радіо-модуля
https://github.com/acehoss/rnsh
Але таки цікаво, наскільки реально користуватись #SSH саме в радіо-етері, я думаю що там буде швидкість равлика і фрізи командного рядка.
Normalement, vous pouvez aller cloner des repos à la fois sur github avec un compte dédié et sur une instance gitlab (moi, ce sera framagit, donc) de la même machine, sans que ça cafouille entre les 2 paires de clés :)
Chacun des comptes a son propre tunnel sécurisé :)
Je me suis aidée de la doc chez framagit, là : https://framagit.org/help/user/ssh.md et une doc plus généraliste de comment fonctionne ssh ici (en anglais) : https://www.datacenterknowledge.com/cybersecurity/ssh-keygen-essentials-how-to-generate-and-manage-ssh-keys
En espérant que ça vous a éclairci sur le fonctionnement de ces commandes et de SSH. 😊

Blue teamers, if you use Bloodhound to map trust relationships that may also be useful to attackers and would like to extend that to your (possibly otherwise unmanaged) fleet of #linux systems, golinhound (https://github.com/RantaSec/golinhound) by my colleague Lukas Klein may be useful to you.
So far it can be used to produce useful data about #ssh keys, #sudo, #Active_Directory, and #Azure / #EntraID integration.

Had some Russian IP come knocking at my router #ssh port with my username only, and chat I am spooked.
@eieio so basically https://slither.io but as #TUI application over #SSH?

Content warning:Repost: snakes.run: rendering 100M pixels a second over ssh
I'd been speculating for the last month or so what Nolen Royalty had been working on recently that had required such high-performance out of the SSH protocol, but now we know: it's massively multiplayer snake.
