UNIX
I am a lover of UNIX or Unix-like operating systems. On my desktop I am using Devuan 13. It is a great OS. It has everything that I need.
As a hypervisor I use Devuan. All KVMs are either Devuan or Alpine Linux, no systemd, and one pfSense.
As a firewall I use OpenBSD.
As VPN service I use WireGuard on my OpenBSD firewall, it works seamlessly.
WireGuard has in my case revolutionized how I can use VPN, since it works perfectly whether I am on LTE or WiFi and changes in connection does not impact the tunnel. I am always connected today. In that case I am protected by my firewall, and by the DNS filtration at home which is filtering ads and other threats. Nowadays I have set it up with three tunnels, all three have different access rules, and my management tunnel has two options; one that goes through 0.0.0.0/0 or a split tunnel VPN where DNS, and only my subnets goes through the tunnel. I am mostly using the split tunnel on LTE and the 0.0.0.0/0 when using a foreign WiFi.
My network is heavily segregated with multiple subnets and VLANs, which is easy with a good switch and OpenBSD.
Some of my WiFi SSIDs requires a certificate to use, and for now I am using Unifi's inbuilt Radius server.
Security and privacy are very important for me so at home I host a webdav-server on a Devuan KVM for my Joplin clients. You may find a great guide here for Nginx.
I host all my calendars and contacts in the Baikal CalDAV/CardDAV server on a KVM vm, and its backend is a mysql-server, which is easy to backup.
I pay for Bitwarden, it is well worth it price of $10, but I use Vaultwarden to host my own Bitwarden service, it is running on an Alpine KVM vm.
I host my files on an Asustor NAS with Devuan installed so that I can make use of ZFS, which is a great file system, and it is very robust. With an OS like Devuan on your NAS your options and nearly endless.
I host my pictures on ente.io, which is a great and privacy oriented service.
I host my music on a navidrome server on my music-server.
I host a local syncthing-server so that I can write from whatever device I want. You can of course save on a smb-share, but if the file is big and you are sitting on a bad LTE connection you have no problems since it saves locally and then syncs to the server.
All of this are possible through all these great open source software and a VPN connection. I am at last nearly free from Windows. Sadly I must sometimes use a Windows virtual machine for my Bible software, but not as much since much functionality is either on an web app or through wine.
Before it is too late we need to assess our view of privacy and security, and act accordingly.
From time to time I might publish something regarding UNIX, which you may find through the TAG Unix.
