Pinned toot

Ever since I was 7 years old, I've been interested in computers, the Internet, and more recently, cybersecurity and social engineering.

I strive to become an excellent cybersecurity engineer. I'm always eager to learn and love meeting new people with similar interests. Feel free to drop me a DM!

Friendly reminder: is a great project to contribute your otherwise idle computing power.

boinc.berkeley.edu

You can set complex scheduling options, either by time of day, battery level, non-BOINC CPU usage, mouse and keyboard activity and so on. This way, it won't take up all your resources when you're compiling or playing videogames.

You can also configure it to only take a percentage of the CPU, a specific core count, or only allow it to run in bursts.

Does anyone know why I can reach reserved IPv4 address spaces like 10.200.0.0/16 from my OVH server?

OK, WireGuard time. First time using it, wish me luck. :blobthinkingeyes:

Hi! Do you know good books on climate research and terraforming? If you don't, can you boost / retweet this so it reaches more people? Maybe some of your followers know! Thanks!

@amolith you can make your CI catching some of them:

Always a good thing to throw an analyzer at your stuff before publishing :blobfoxwinkmlem:

Just finished testing and deploying my Ansible script for status.kydara.com/

I'm using Vigil. It updates automatically and notifies me if anything goes wrong. This should make maintaining the whole infrastructure much easier, I hope!

forces immediate disconnect in openssh

There should be some kind of heartbeat service by default that pings both ends of the connection every few seconds if there's no other activity going on (such as the user typing something in, or receiving text from the remote server) that terminates connections after a reasonable amount of time, for example 30 seconds. This should of course be overrideable for extremely high latency SSH connections such as satellite Internet uplinks.

I cannot easily put into words how frustrating it is to have an SSH session be terminated remotely (for example, by pulling the plug on the physical server, switching VPNs or deleting a cloud instance), yet the SSH session will simply hang for a while until it eventually realises the remote server is not responding. And the timeout starts counting from the moment you try to type anything into the terminal, so you have to forcefully close the terminal window if you don't want to wait.
