Selfhosted
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.
Rules:
-
Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.
-
No spam posting.
-
Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.
-
Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
-
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).
-
No trolling.

Wipe and start fresh
Are you joking? Why would I start fresh?
Because you don't have a way to know what's been compromised. Take your data only and make sure to verify nothings been tampered with.
Trust me it will be better in the long run.
Yeah, I dont feel like setting up a whole cloud infrastructure on a hunch. I‘m running like 15 different services and they are all compartmentalized. It would take weeks to reset all this. So far nobody got anywhere from what I can see.
One word of advice. Document the steps you do to deploy things. If your hardware fails or you make a simple mistake, it will cost you weeks of work to recover. This is a bit extreme, but I take my time when setting things up and automate as good as possible using ansible. You don't have to do this, but the ability to just scrap things and redeploy gives great peace of mind.
And right now you are reluctant to do this because it's gonna cost you too much time. This should not be the case. I mean, just imagine things going wrong in a year or two and you can't remember most things you know now. Document your setup and write a few scripts. It's a good start.
I get your point. Ansible is quite interesting too. I do document most of the things I do but I have to admit I have been slacking a bit, recently. There is just so much stuff that needs doing and a lot of interesting projects to learn about that sometimes stuff gets forgotten.
My personal impression of the linux space is still that folks get dumped on by the community for not being immersed in the nitty gritty though.
Thats neither fun nor will it work to get more people interested in linux. People make mistakes, learn to help without judging.
Have a good one.
I know what you mean. Most people mean well, some are a bit too aggressive, but probably also mean well. I honestly sometimes roll my eyes when I start reading about tailscale, cloudflare tunnels etc. The main thing is not to expose anything you don't absolutely need to expose.
For access from the outside the most you should need is a random high port forwarded for ssh into a dedicated host (can be a VM / container if you don't have a spare RaspberryPi). And Wireguard on a host which updates the server package regularly. So probably not on your router, unless the vendor is on top of things.
Regarding ansible and documenting, I totally get your point. Ten years ago I was an absolute Linux noob and my flatmate had to set up an IRC bouncer on my RPi. It ran like that for a few years and I dared not touch anything. Then the SD card died and took down the bouncer, dynDNS and a few other things running on it.
It takes me a lot of time to write and test my ansible playbooks and custom roles, but every now and then I have to move services between hosts. And this is an absolute life saver. Whenever I'm really low on time and need to get something up and running, I write down things in a readme in my infra repository and occasionally I would go through my backlog when I have nothing better to do.
Thanks for elaborating! This is very helpful and I appreciate it. Will definitely check out ansible.
I think i‘m probably on my way there anyway as I‘m setting up my own git forge and starting to use proper versioning.
Then I‘ll probably try out ansible on some vm or new device. Have a good one!
Just be careful
Wow, a lot of people would set up a new server because of intrusion attempts in a log i guess. If I did that in a job I‘d get fired for doing nothing else but resetting everything every week.
As an admin, you have to keep the CTO from using „master“ or „admin“ as the ssh password on a production server. Just so you know what level of stupidity makes the big bucks out there.
As an admin I’d question why the CTO has a login on a production server.
You would do well listening more when you ask for advice.
For Chiefly reasons of course. Now whether or not that server is active in the cluster is another matter entirely, but hey if it makes him/her feel important /shrug
You would do well keeping your condescension to yourself. Blocked.
Oh no, entitled asshole who talks down to everyone who has an answer for them blocks me. Whatever am I to do.
You're saying you see a bunch of login attempts on your router, but you don't think they actually got into it?
If you have everything on docker compose migrating to another host is pretty easy. I could probably migrate my 11 stacks of 36 containers in 2 to 3 hrs
Why would it take 2 to 3 hrs? Download time of container images?
Figure ~45 minutes to run to the liquor store for a decent single malt, another ~25 minutes for the pizza rolls, quick power nap, wake up and redeploy. That's about 2 hours.
Pretty much this. Lot of padding in those numbers or waiting for some manual things to install etc
If everything works well, I could probably do that too. But I‘ve had too many obscure little things happen that 10x the amount of time needed so I always plan for the worst case.
Also, my point was that people are being massively overreacting due to the fact that my logs showed signs of attacks, not intrusion.
I run many servers and the commercial ones I am much more slow and careful with. Every public facing service has attacks in their logs and I deal with them. I know what experience you guys have but its not hosting public services.
the arrogance with which people suggest someone is incompetent is baffling. Not talking about you but quite a number of comments where condescending af.
Thanks for the advice with ansible. I might actually give this a go.
If they had access to a machine, the first thing you do is install some kind of root kit so you can get access again later. This could be as small as modifying an existing binary to do things it isn't supposed to do.
If they didn't access any machine, your fine.
Thanks for elaborating. I appreciate it. To my knowledge, nobody had access to the network or the machine.
