Create your own Certificate Authority using bare OpenSSL - is the outcome of this week's tinkering. I wrote the basic things down as a step-by-step guide so we can all have nice things 😃

It intentionally omits more advanced stuff like intermediary certificates, typically found in a more mature setup. The goal is to get your hands dirty, not run the next Let's Encrypt. That'll be the next blog post ... 😉

I need to cool my home lab better
I home lab is in my room and it is 31 c right now :neobot_sign_hot:

#homelab #homelabbing #server #computer

I’m really getting to reflect on the paradoxical nature of #homelabbing, #selfhosting, and #technology in general as I work to build a full-spectrum #cybersecurity stack from basically the ground up. The paradox being that if I could afford to, I would absolutely pay somebody or somebodies to host this crap for me and just use it as a service, but by so doing rob myself of the experience gained by building it myself; however, in struggling to build it for myself, I spend less time learning how to use the tools properly because it’s damned near impossible to get them all working together without some sort of sacrificial ritual.

To clarify, I’m not above #ritual #sacrifice, but none of the witches in the local coven will teach me the right one. Turns out broomstick jokes fly about as well as actual broomsticks. Ha! #rimshot

Almost there.
The server is basically ready — it just needs a little more tweaking.
One silent fan in the power supply, and everything will finally run as it should.
Patience, small upgrades, and a lot of love for quiet hardware.

The server is ready. A bit of hardware, a bit of chaos, a lot of patience and it finally came to life.

There's something that feels oddly cute about me and my father's NASs >w<

You are having a hard time connecting to the internet...
Connected but no internet.

(It's me. I am the fren who is the novice homelabber. Very happy my roomie is chill.)

#mewishthoughts #server #homelabbing

about 2 weeks since i started #homelabbing
changes and improvements since,

- i had initially everything setup on wifi and that was hella unstable, i would get random connections drops. i bought an extension board and connected everything via ethernet to my router's internal switch.
- i had been using my old dell inspiron n4010 as my #NAS but the usb 2.0 was starting to become a painfull bottleneck and i eventually shifted the HDD to my thinkpad with a usb 3.0 port. unsure how i wanna use the dell now, i would probably shift adguard home and other light services over to it.
- have setup #dockge to easily manage docker containers and "stacks" as they call it.
- have setup a few other services including but not limited to, #navidrome, #actualbudget and #karakeep.

I might be on the precipice of starting my #homelabbing endeavor. If anyone has advice or experiences to share for setting up a personal file server and self-hosting websites, all would be appreciated!

Kann die AI Bubble bitte mal platzen ? Ich brauch neue Festplatten und RAM.
Danke AI.

the first day of the year is as good a day as any to start building your #homelab
day1 of #homelabbing

so i have got two spare machines, a #thinkpad t460s and a dell inspiron n4010.
today i've put #debian trixie stable on the thinkpad which will be my main lab, and #openmediavault on the dell to make it a #NAS which will barely run any dedicated services.

moreover, i setup #docker and #tailscale. after which i started running the #vaultwarden and #AdguardHome containers.

current roadblock:
tailscale serve only let's me serve a single service via a single domain, i wanna figure how i can use multiple different domains on my local network so that i can access them individually at the same time.

i.e. something like,
vaultwarden.smth.ts.net
adguard.smth.ts.net

i haven't figured that out yet

Finally managed to redo the wiring of the rack of my #homelab #homelabbing #homelablife

Seems like #homelabbing is going to get a lot harder

Succesfully installed Proxmox and then Ubuntu Server in a VM, no idea what to do next (beside upgrading my hardware as I have limited ram and CPU cores) but I am liking this so far #homelab #homelabbing :blobble_bobble:

I'm thinking of switching from #spectrum to #frontierfios. What experience do you have any experience with Frontier Fios, particually in the #connecticut area? I have an extensive #homelab and lots of networking experience, so I know the devil is in the details.

#homelabbing #homelabs

Trying to decide which type of homelab to build has thrown me into a rabbit hole and I can't get out at this point, I am like...

Ubuntu server + Dockers??
TalosOS + Kubernetes???
Nextcloud for Cloud service?
Tailscale or not to Tailscale??

I only have ONE old machine and not a rack with multiple servers, and it would be my first one btw.

Nach mehrmaligen DSL Ausfällen der Telekom und Beinträchtigungen im Homeoffice konnte endlich, in zähen Verhandlungen, Budget für eine Backup WAN-Verbindung im Hause Wombat allokiert werden 🥳🤪 #homelabbing #arbyte #homeoffice #hundoffice

How often does it happen to you that you spurn starting to use some sort of web-based #OpenSource *server* software (that you were considering #HomeLabbing, or installing in the #cloud), merely because the underlying frameworks used are problematic, hard to maintain, hard to secure, believed to be legacy, etc? Examples: node.js, npm, #React, #kubernetes, bootstrap, #Docker, yaml, or others you might loathe (please list).
