I run three piholes with gravity sync and have none of the problems you describe.
But pihole isn’t big magic it’s basically a dnsmasq with some management stuff around it. you could host a dnsmasq yourself and just fill the filter rules in the config file your self with ansible. The adliges are publicly available just get them with Ansible and parse them into a dnsmasq config template.
Here is an blog about it. https://alblue.bandlem.com/2020/05/using-dnsmasq.html
Have a look at cloudflare tunnel. You still have vaultwarden in your lan but accessible from the world. No open ports needed.
I use traefik as reverse proxy in front of my services and have it generate let‘s encrypt certificates with dns-challenge. Do Inexpect MIM attacks at my home. No not necessarily because they would be physical access to my infrastructure but yeah having it this way feels just better.
Not sure if the tik Logs traffic that detailed. But you could setup a remote logserver (syslog-ng) and have the tik send it logs to that and then push them with logstash into an ELK stack and use that. Or not Loki and Grafana analyze the log and build the dashboards you need/want.
I either use public available containers like from docker hub or other registry. Or if I build them myself I have them pushed to my own self hosted registry with a minio(s3 compatible) backend and mirror the MinIO instance to a VPS.
All dynamic data is saved with the VM backup the container runs on or is backed up with rdiff-backup to an offsite location.
Sure you can. The question is what are the exact specs and what do you want to self-host?
I have two HP EliteDesk 800 Mini as a XCP-NG pool. Both with i5 6th gen only but with 64GB each and they run about 20 VMs distributed between both.
Sure they won’t be able to perform large language model tasks but for most self-hosted services they are more than powerful enough.
Keep dreaming little one. You leave traces as soon as you go online even when using Tor and supposedly no logging VPN. In a way those have to log something about you for billing reasons alone.
True anonymity and privacy is only offline possible.
I host my own VPN. All I need when I am out and about.
Simply put, yes. Its a widely used software so atleast you can trust that the software itself is secure and shouldnt cause you any problems
Windows is also widely used software an has vulnerabilites all the time. Because a software is used widely doesn't mean it's safe and secure.
Awareness of security and vulnerabilities.
Hosting anything is easy doing it secure is the hard part.
The problem is a lot of people here are beginners and have no real clue about network security. And opening a port is opening a door. If you have a bouncer that clears people beforehand then you can keep the door open. But you will still need to keep your bouncer trained so he can take care of people you don’t want. Same with software. Keep it updated and have security enhancements in place like 2FA and analysis tools like crowdsec or fail2ban. And the open port might not an issue at all.
But if you open a device like a NAS (cough QNAP cough) then you have a higher security risk.
TLDR; if you know what you are doing it might not have implications.
