🎄 Advent of Donations - Day 2 🎄

Today's donation of $50 go to Daniel García, maintainer of the Vaultwarden project.

In the past few days I’ve seen talk about RAM prices shooting up due to demand from big datacenters.

Today I read that a historic brand like Crucial - I own plenty of their hardware, including SSDs - is dropping consumer products to focus on gear for those same datacenters.
The result (or maybe the intention?) is to push people away from self hosting, undermine the OwnYourData idea and make everyone depend on huge datacenters for life.

So much for owning your data.
So much for decentralisation.

Because taking down one giant datacenter is far easier than taking down thousands or millions of individual nodes.

Friends and colleagues, don’t trade your freedom for a bit of convenience. Once you give it away, getting it back is very hard.

Always Own Your Data.

#OwnYourData #SelfHosting

Il web che amo.
Quello dei piccoli blog indipendenti, magari ospitati su qualche VPS dove si offrono anche servizi open source e privacy oriented, istanze del #fediverso, e tanto altro.

Si può parlare di #indieweb?
In ogni caso, impegniamoci per alimentare un WWW più sano.

Per non creare un'accozzaglia di url, mi limiterò a taggare alcuni profili (in ordine sparso), da cui poi ricavare i link:

Ever messed up an update? We got you covered! Simply restore your Snapshot!

You can now also manage (create, delete, restore) a snapshot of your Box! If you ever messed up your application, OS update or anything else - simply go back to your last snapshot and try again! This way, you can test and learn #BSD even better and easier!

BoxyBSD allows you to manage snapshots of your Boxes, now!

Aaaand we're back!

Pssst! BoxyConnect comes soon to @BoxyBSD!

BoxyConnect allows you to create a private network / private link between multiple boxes at BoxyBSD. And the best? You can even create this over different locations/countries to provide you more flexibility.

You can simply assign any RFC1918 addresses on your new additional network interface on both sites and communicate in your own private network - even miles away.

This feature is currently in beta and will hopefully be available to everyone (just like all other services of course for free). Enjoy #RUNBSD!

This new feature is powered by @gyptazy!

@drscriptt Same, send and receive, and I'll share logs. #selfhosting

#selfhosting folks:

How, really, louder are ironwolfs 10tb+ compared to we red 6tb?

@rainy Get a
VPS (Vultr, Digital Ocean), a domain (Porkbun). Learn some DNS (BIND) and email handling (Postfix, maybe Courier IMAP). Pick a Fediverse server (Friendica, Mastodon). There's a lot to learn but you'll become more powerful for knowing it.

PS: Dovecot is the common option for IMAP but they pulled a fast one recently with their config that's impacted lots of folks, and I've lost faith.

I made a few updates to my solar powered website.

Most of all, I fixed the uptime counter. I also made some tweaks to the wording, the gallery and the overall site design.

In early September, The Matrix Foundation homeserver went down.

I'm extremely proud of our SRE team. They had a Disaster Recovery Plan and monthly exercises to apply it, resulting in no data loss despite a 24h outage.

I've learned a lot about how to properly backup/restore a Postgres database when writing this post with SREs. We also learned how to better prevent and be resilient to human error.

Thanks all for the hugops during the outage!

Pretty interesting how an old hardware works well and compute well in the strange configurations.

Prereqs: Intel Atom N2800 1866 MHz and 2 Gb RAM.

Since there are no NetBSD builds of xray-core and v2raya — I spin up a FreeBSD VM inside the Qemu and without NVMM accelerator (not supported by my CPU). Execute these programs inside this VM — and the server still running and even doesn't overload

CPU usage graph from Munin. The graph shows 5-10% CPU usage. The graph rises to near 5% at near 11:40. With one visible spike to 120% at near 12:50.

Load average graph from Munin. Overall usage were at near 0.3 but raised to 0.8 at 11:30. With one visible spike to 2.8 at near 12:50

The memory usage by category graph. It shows rise of anon memory from 0.3 Gb to 0.8 Gb at near 11:00 or 12:00.

Alt...

Processes graph from Munin. It shows that there are near 53 processes before 11:00 and near 65 processes after this time.

Sending mail from residential ip be like:

It's easily solvable using a "free" SMTP relay. But the privacy benefits of self-hosting are lost.

I'm using smtp2go to deliver to outlook and gmail. I have no idea if smtp2go is good or no. Do you have any recommendation?

I'm strongly leaning towards giving up hosting my own email. I've been doing it for 25 years this November, and I'm about done with jumping though all the hoops needed to get mail delivered.

Is there a company you can recommend that will take over all the work and give me an imap account?

I don't mind paying a reasonable sum per year, but I'd really like my email to work again consistently so I can move away from google. #email #selfhosting #SellMeSomethingIWant

Made my FreeBSD server at Netcup ready to host multiple isolated applications with automatic https via Let's Encrypt.

Internet → Server → PF firewall → Caddy jail (reverse proxy) → Individual application jails

Each app gets its own isolated jail for security, while Caddy handles all the routing and https. PF keeps the front door locked.

All of course with IPv6 first, where every Jail has it's own public IP address and using NAT for legacy IPv4.

Love how FreeBSD jails make this kind of segmentation so elegant.

Traffic flow diagram

Me: I'm gonna self host a mail service on an old laptop, with my *very* residential and dynamic IP address. What could posibly go wrong?

Spamhaus: *checks ISP and IP range* You are not supposed to do that.

Outlook smtp server: "550 5.7.1 Get lost!"

Gmail: I don't like you. But it's only one mesage, and DMARC is good: You go to spam folder.

spambots: LOOKS LIKE MEAT'S BACK ON THE MENU, BOYS! 👹

Besides some test mesasges, 100% of the traffic is spambots sending invalid commands trying to find a vulnerability, I assume.

In the linux world I feel confident with my monitoring tools, iptables and fail2ban. But in NetBSD everything is new to me. So I have to be extra careful.
