What type of course would you find most valuable? (Comment with any suggestions or other thoughts.)

I've now nuked and paved my 4B for the 4th time. By now I've learnt from experience that SDs aren't meant to last holding the entire filesystem. After another case of "Segmentation fault" (likely corrupted SD), I've moved the filesystem to a USB. Depending on performance, I may reattempt moving everything to a partition of a 1TB HDD being used primarily for .

This weekend, success =
- Steadily growing local media server
- Setting up connection to my for IP camera and Plex streaming
- Isolating work devices on the LAN
- Discovering no new issues (more to come, I'm sure).

My various setups (primary machine, home etc.) seem to challenge me weekly, but the satisfaction of fixing issues and taking back control makes the stress worthwhile. I love , and every day is a school day. I recently repurposed an old 1TB HDD as a and want to try some kind of , but Netflix has become an expectation in the household. Share your / other self-hosting project ideas!

Now running minimal vanilla on my 4B for . Unfortunately I tried but failed to boot with root mounted to . After the third attempt's kernel panic due to "no working init found", I gave up. I now at least have swap disabled on and Pi-hole logs disabled. Any other tips for SD longevity?

What the F*** is doing in my Pi's apt sources list. This is some bitter irony - I use this almost exclusively for . I was wondering what all the hype was about recently and now it's clear. Where can I find out more about why this has happened and what, if anything, is being done about it?

I've now created a public room at freelearningfoss:matrix.org -- My intention is to use this room to bring together anyone interested in contributing to made with . I may soon start a range of courses on subjects. Join the room and share your thoughts!

It was all going great with my jails on two of my VPSs until I changed the port SSH listens on. F2B seems to only work when SSH port is 22. Anyone experienced this? I wasted enough hours debugging this that I've now removed F2B out of frustration.

I think it's time I tried ... I watched a video intro to it made by one of my favourite new video content creators, : invidious.snopyta.org/watch?v=

I was recently recommended tryhackme.com and I can confirm it's a brilliant site. I've been going down the rabbit hole recently and it's great to have a site like this with lots of interactive , a lot of which is free. I may even submit my own learning content someday.

I had ~60GB going spare on my so figured I may as well make the most of it and set up for file sharing across my LAN. I'm allowing access only from mine and my partner's IPs (which are bound to our MACs) but I'm concerned the share isn't encrypted, so anyone could just walk up to the Pi and take out the SD. Any suggestions for securing shares?

interface renaming anyone? On multiple occasions I've had issues. For some reason my loopback interface is called "rename1". Support assures me this is normal/default config, but it just doesn't make sense to me. Why not "lo" for loopback, and why did it get renamed in the first place? Soon I'm just going to get rid and start fresh with trusty .

I've finally figured out the tool for managing my credentials. It works nicely and I've also managed to set up a challenge-response key for use with .

I'm currently working on a to run after login, which does the following:

1. Bring down WiFi interface
2. Spoof MAC
3. Generate random word
4. Change hostname to random word
3. Bring up WiFi interface
4. Connect to VPN

Should I write it in or ?

Currently written in Bash, but despite the hostname changing successfully when the script runs, running 'hostname' afterwards outputs default hostname...

I would love to try flashing a with /#Libreboot at some point, but after seeing what it involves (flash plugs etc.), I'm not so sure I want to step any closer to the edge of that rabbit hole. I can already see the hours of trial and error and stress, with potentially nothing to show for it. I have a habit of putting too much on my plate...

Can anyone recommend an online store, preferably accepting crypto and based in the , which sells pentesting gear ( adapters suitable for monitor mode etc.)? All roads in my research seem to lead back to the terrible two I want to avoid: eBay and Amazon.

I know of and , but neither sell wifi adapters (which is specifically what I'm after).

that without full disk encryption or locking down your config, an attacker with physical access to your system can simply edit the boot parameters (adding an "s" for single user (root), or "init=/bin/bash")) and boot straight into a root shell.

What's all this about then - “SUID sandbox helper binary was found, but is not configured correctly” Third time I've tried to launch an Electron app and this has happened. Anybody know of a safe, permanent fix? unix.stackexchange.com/questio
