I do like the challenge of POSIX scripts.

I’ve remade a handful of GNU extensions as POSIX scripts/functions. I also just enjoy trying to be as minimal as possible and building my own tools. It helps me understand how operating systems in the process too

Most of my work is on codeberg

It can be a challenge though since all searches default to bash/GNU extensions

I started with Mint. My next and last stop was Alpine. I started trying to host my own website on a Raspberry Pi and ended up switching my laptop over to Alpine so that I could consistently learn on one operating system

I also found a side hobby in making POSIX portable scripts which goes nicely with self-hosting. It’s great having a lean and customized desktop just for myself even if it took a long time to learn how to make it all work

I have a painfully good social memory. I remember social interactions in vivid detail. I generally act like I don’t remember as much as I do because it can come off as creepy or rude. I won’t tell people this until I’ve gotten to know them well enough to share.

Names, numbers and that thing that was in my hand .5 seconds ago? Giant black hole…

I also haven’t seen any bot activity after I started using wildcard sub domains. My ISP blocks all incoming on common ports so I also use uncommon ports. I assume the combination of the two makes it too time consuming to find me.

I hid my ssh port with a wireguard connection so I also don’t see any attempts on my ssh port anymore either. My logs, including fail2ban, are quiet and boring.

It’s nice to have a quiet corner of the internet for myself.

I let a patch in the backyard grow with grass, clover and other native plants that happened to grow in there. I keep it trimmed and use the cuttings to layer my compost pile.

My parents and neighbour hate it:

As much as they hate it, the bunny crop are coming in nicely and they don’t want to pick a fight with the bunnies. The bunnies love it in there, they have safe space to hide but still get to enjoy the sun. It’s better than the suburban wasteland of cut-too-short lawns where there’s not many places to chill.

In order to make sure my beans survived the first few weeks, I planted so many beans early in the year so at least some would survive to maturity.

I also keep leafy greens and my veggie scraps compost pile in a small gated area and the other stuff has to battle it out in the ungated gardens.

It’s going okay so far but things have only recently started to pick up so I’ll see where it goes from here.

I’m going to post all the commands I use because I think that may be easier to follow. All the commands I’m posting will include the --dry-run option so if anyone tries to copy/paste this into their terminal, no actions will be taken. Instead it will show you what is going to happen if you ran the command without any changes.

As I mentioned before, each partition will require it’s own command. The easiest way is using lsblk. Below is my current setup and here you can see I have 5 partitions. One partition is a swap so I will only be working with 4 partitions, /, /boot, /boot/efi and /home:

dell:~ $ lsblk
NAME                  MAJ:MIN RM   SIZE RO TYPE  MOUNTPOINTS

It’s good to first check what partitions you are using. My Raspberry Pi’s (ARM) only have / and /boot for example.

The following rsync commands are what I use to make a complete backup of my system. I do exclude a number of directories because they are for temporary stuff like ram, processes or even devices/drives. It’s also important to exclude the specified backup directory to avoid recursing into the backup directory and filling up your storage space.

I have a manual backup location and automated backup location. The following is for my manual backup location in /backup/main on my system. This location can be changed to wherever you want your backup.

# Backup
# /
rsync --dry-run --archive --acls --one-file-system --xattrs --hard-links --sparse --verbose --human-readable --partial --progress --numeric-ids --delete --exclude=/backup/* --exclude=/boot/* --exclude=home/* --exclude=proc/* --exclude=sys/* --exclude=dev/* --exclude=tmp/* --exclude=run/* --exclude=mnt/* --exclude=media/* '/' '/backup/main/'

# /boot/
rsync --dry-run --archive --acls --one-file-system --xattrs --hard-links --sparse --verbose --human-readable --partial --progress --numeric-ids --delete --exclude=lost+found '/boot/' '/backup/main/boot/'

# /boot/efi/
rsync --dry-run --archive --acls --one-file-system --xattrs --hard-links --sparse --verbose --human-readable --partial --progress --numeric-ids --delete --exclude=lost+found '/boot/efi/' '/backup/main/boot/efi/'

# /home/
rsync --dry-run --archive --acls --one-file-system --xattrs --hard-links --sparse --verbose --human-readable --partial --progress --numeric-ids --delete --exclude=lost+found --exclude=.cache/* '/home/' '/backup/main/home/'

# Restore
# /
rsync --dry-run --archive --acls --one-file-system --xattrs --hard-links --sparse --verbose --human-readable --partial --progress --numeric-ids --delete --exclude=/backup/* --exclude=/boot/* --exclude=home/* --exclude=proc/* --exclude=sys/* --exclude=dev/* --exclude=tmp/* --exclude=run/* --exclude=mnt/* --exclude=media/* '/backup/main/' '/'

# /boot/
rsync --dry-run --archive --acls --one-file-system --xattrs --hard-links --sparse --verbose --human-readable --partial --progress --numeric-ids --delete --exclude=lost+found '/backup/main/boot/' '/boot/'

#/boot/efi/
rsync --dry-run --archive --acls --one-file-system --xattrs --hard-links --sparse --verbose --human-readable --partial --progress --numeric-ids --delete --exclude=lost+found '/backup/main/boot/efi/' '/boot/efi/'

# /home
rsync --dry-run --archive --acls --one-file-system --xattrs --hard-links --sparse --verbose --human-readable --partial --progress --numeric-ids --delete --exclude=lost+found --exclude=.cache/* '/backup/main/home/' '/home/'

It’s been a while since I last researched these options so I’ll give a brief explanation of the types of options I used. I’d suggest having a look online or at the man page to get a better idea of what each option does.

Options:

--dry-run Only displays what rsync will do, remove this once you are ready to commit any syncs/changes

archive --acls --one-file-system --xattrs --hard-links --sparse Helps preserve file attributes and other information. I think hard-links is also used to reduce backup size. There are many rsync guides that will give a better explanation of how hard-links work

verbose --human-readable --partial --progress will display visual data about what rsync will do

--numeric-ids I use this because I store multiple device backups on a single drive which gets copied to other storage devices. This stores file ownership information as numeric values to prevent ownership issues when restoring

--delete this will force the destination directory to match the source directory completely. If you delete a file from the source directory, when you perform a sync, it will delete the same fie in the destination directory. This can be dangerous if you are not prepared for it. This is why --dry-run is so important and useful.

Extra options: My automated scripts use 2 additional options. I keep a rolling set of 4 backups (One month of weekly backups). I create a new directory /backup/updating and use a symlink from/backup/latest that points to the most recent automated backup. After the backup is created, I rename /backup/updating to something with a timestamp like /backup/backup_2026-07-01_1782882013

--mkpath will create any non existing directories specified in the command

--link-dest=/backup/latest/ will use the unchanged files from this directory to help reduce backup sizes. I think this is called an incremental backup

This has been the most reliable way to handle backups for myself. I do run into issues with docker/podman containers sometimes and will have to manually delete those directories. I haven’t figured out how to deal with that issue yet but fortunately it’s easy to find those directories. Running the command will give errors about what directories can’t be removed which makes it easy to hand delete them in another terminal window.

Timeshift is essentially a gui on top of rsync anyway, if you look at what it’s doing behind the scenes.

That’s the reason why I chose to learn rsync. I was frustrated with Timeshift. It failed to restore some changes multiple times. It gave me issues with docker. It also had default excludes that were annoying to change as well.

I then learned how to make a complete system backup with rsync itself. /, /boot/ and /boot/efi/ has to be done on separate rsync commands. Basically one command per partition.

A restore involves flipping the source and destination in the rsync command. It also allows me to boot into a live USB and perform a restore in the event that I really mess up and can’t perform a restore normally through the installed OS.

By leaving behind the GUI, I got a lot more flexibility. It’s also a lot more reliable and I’ve had a lot less restore issues.

Timeshift is the reason I learned how to use rsync. I wrote my own script that made a more complete backup and can automate multiple incremental backups with a customizable max number of backups.

It’s simple and so much more reliable. Even when I forget to test my backups, they still work when the time comes.

At least Timeshift taught me how to use rsync, so there’s that.

I’ve been trying to find a balance between what I currently own, what I can do with it and using as little outside resources to self host. I’m also cautious about what has access to the internet which limits what I host.

I have two Raspberry Pi’s. One is only accessible through my home’s local network through my WiFi Extender network. That WiFi extender also helps hide my personal network from my ISP which see’s everything connected to the main modem/router. This Pi is strictly for my IoT devices.

My other Pi is a web facing server. It has Caddy and Kiwix. It hosts a static blog, simple file server which servers my git repositories, some survival ebooks, plain text recipes and a bunch of programming related resources. Kiwix has a bunch of wikis, Wikipedia to survival stuff, vegetarianism, coding stuff and things surrounding those topics generally. I generally avoid anything that uses databases because I don’t have the energy to learn, maintain and protect that. Plus I have a focus on small, low powered minimalism.

Those Pi’s both use Alpine Linux. I chose Alpine because it’s small and uses less common tools. doas over sudo, OpenRC over SystemD, and Musl over glibc. It’s a bit of security by obscurity but I’ve also made efforts to harden Alpine Linux itself too. I’ve disabled a lot of kernel modules, made strict firewall rules, and made sure to include the use of apparmor. I’ve also written all my backup solutions and maintenance scripts myself and tested as thoroughly as I am capable of. I also avoid complexity by keeping things as minimal as possible to reduce the surface area of any possible attacks.

I use podman containers to keep everything in the userspace. Caddy is my reverse proxy which means only one port is freely accessible to the internet. I also use a wildcard cert to obscure my publicly available information and use an uncommon port instead of the standard 80/433 ports. Because of the wildcard cert/uncommon port, I receive no bot traffic so I don’t feel the need to use Cloudflare or Anubis. I’m hidden enough and the only people I want on my blog/file server/Kiwix wiki’s are close friends.

For SSH, I’ve hidden all those behind WireGuard so the second open port to my web server looks hidden from scanners (at least that’s how I understand it). I used to use a custom port which only got about 15 hits a week from bots appearing from the Netherlands. That number has since dropped to zero after setting up WireGuard. I’m sure the bots are attempting but they aren’t making any appearances in my logs and that’s good enough for me.

I’m happy more talk about security has been popping up lately. So many websites focus on getting things running and just don’t take any time to talk about security. I had to switch from docker to podman because docker had so much control over iptables that never got reported to ufw which was a concern for me. That point is rarely talked about since it’s so easy to copy and run a docker-compose.yml file.

I often see claims that Alpine linux is just for embedded systems. I wanted to highlight to other people that there is far more to Alpine than embedded systems or being used for containers.

It’s mininal like void but still very flexible and capable if people are willing to work with Musl, BusyBox or OpenRC. It’s a nice option for anyone who has issues with SystemD or may want to depend less on GNU tools.

Like any distribution, it doesn’t fill everyone’s wants or needs but it seems to have grown more than serving just embedded systems.

I use Alpine as my desktop daily driver. The setup-desktop [link] and setup-devd [link] scripts that come with Alpine are convenient for setting up a desktop environment.

There still is some extra work to get things working but the wiki has a good tutorial page which is a good start for setting up a desktop environment on Alpine.

I do think Alpine is quite flexible beyond embedded systems. That’s a lot of effort to include desktop environments in their OS or even in major version release notes.

Aaah that’s good to know. I’ve seen HAproxy mentioned before and this was the first time I looked at it.

I am happy I went with Caddy because networking is not my strength and Caddy is quite simple in comparison to other reverse proxies. Nginx config files will forever look like scribbles to me.

I don’t know about the limitations of using an uncommom port though because my needs are quite small and obscure by design. I do wonder if other people could benefit from using wildcard certs + uncommon ports. Watching bots/scrapers drop to zero attempts and stay zero has been really satisfying and I haven’t had the desire to use outside services like Anubis or Cloudflare.

I know someone out there with itchy fingers is ready to warn that obscurity isn’t security and I wouldn’t deny that. However, I do believe obscurity layered with security is valid as long as security takes the main focus.

For the past year I’ve been learning to self host minimally on a used Raspberry Pi 5. I do have a Pi 4 as well but that’s dedicated to HomeAssistant for the small handful of lights and switches it controls.

Both Pi’s run Alpine Linux with Podman containers. For my Pi 5 server it runs Caddy as my reverse proxy/SSL cert handler plus another contained for Kiwix. It’s super simple. Caddy also has a basic file server for me to host my git repositories as well as hosting my static site.

The static site is based off a script I found called BashWrite but it hasn’t been updated in a year so I decided to add some of my own changes to it here. I also fixed up some of the English grammar since the original creater wasn’t an English native speaker.

I’m still focusing on the background stuff but I’ve put a lot of effort into security and hardening. I’ve written all the maintenance (backup, keep-alive, updating) myself using POSIX portable scripts which can all be found on my codeberg page. It’s been a long process but I’m nearly there. I just have to switch from iptables to nftables and add secrets to my Caddyfile configuration to hide important keys that are currently sitting as plain text. After that I can focus on my blog/static site.

Since I’m not doing this for a business, I’ve decided to use a wildcard domain for my SSL cert plus an uncommon port as a low effort way to hide myself from bots/scraper. Also I set up Wireguard infront of my SSH connection to also hide from bots. My log activity only shows my own activity which is comforting to know, especially since I’ve seen just how active bots and scrapers are in comparison to a year ago when I was just getting started and beginning to learn things.

It’s really cool to see another minimal project like this and I think it’s refreshing to see. A lot of the times I see people with dozens on intensive services running and I feel a bit out of place with my scaled down self hosted project.

My only question about your setup is about HAproxy. How important is a load balancer for your site? I don’t think I will need one for myself since the traffic will mostly be for myself and a few people I know personally but I am still curious about how it works and how effective it is for your setup.

How frustrating, last time I tried to learn nftables, I gave up because the documentation was just not as good or as widespread as iptables.

I hated dealing with iptables already so my brain definitely doesn’t want to spend the energy learning something else that’s similar to iptables.

I was so close to having a nice stable, self maintaining home server that I didn’t have to think about on a technical level before this announcement :(

A few years ago, during the spring and summer I’d wake up at 4:30-6 in the morning to the sound of birds. Now it’s quiet. I don’t think I know anyone else who has noticed or cares.

All I hear are the sounds of motors… I hate motors.

It makes me sad and feeling a bit empty.

This was a number of months ago so I doubt it would be remembered anywhere at this point. After that, a number of posts I commented in were also removed as well. It was very confusing because everything seemed appropriate for the community. I do look forward to seeing how this community grows/changes now.

I’ve taken a very minimalist approach to self-hosting but I’ve given extra attention towards security. I feel like security doesn’t get talked about as much as it could be. It’s especially important these days with bots roaming around everywhere.

I also use some unconventional methods that I’d like to share (layering security with obscurity with a focus on security first). It’s not a one size fits all solution but I can stay private while exposing my server with minimal tools. It works for me though and my logs haven’t shown any outside activity besides my own.

I stopped posting and commenting on this community because things kept getting deleted even though it was all very clearly about self-hosting. It was very disappointing because I spent a lot of time on my contributions. One post I made a while ago was about self-hosting security and had tons of activity only for all that information to be removed over rule 3. Very confusing and disappointing.

I’m interested in seeing how the vibe around here changes going forward. Maybe I’ll be less cautious about participating.

I just use SSH+Rsync for everything. I traded two-way sync for minimalism and reliability. I’ve had nothing but headaches with anything else, especially Syncthing.

My Computer and both Raspberry Pi servers both run Linux and I have Termux installed on my Android phone so OpenSSL and Rsync are easily available.

I made a script that runs Rsync commands from files containing all the information which easily swaps source/target files so I can easily transfer in both directions with a simple command line option. It’s reliable and simple and I’ve had a lot less headaches troubleshooting the rarely occurring issues.

It’s mind blowing to me that anyone wants to live forever in this life or the next.

From my experiences, many people that are afraid of death are also extremely unhappy being alive in the first place. They are constantly struggling with the fear of their life coming to an end that they miss being able to be in the moment. That’s stressful as fuck.

Everyone poops. Everyone dies. That’s just a part of life. Not a whole lot in this universe has the opportunity to see beautiful things and experience emotions.

Sadly, people who are afraid of death like to make it other peoples problem. Generally, I prefer the company of a pile of shit over those people. A pile of shit won’t think twice about nurturing new life no matter what it is and that’s the kind of vibes I can support.

Anyways, my retirement plan is still extreme sports. If I’m going to leave life behind, I’m going out in style.
