  • The thing is, it only breaks sometimes (usually when I need it the most lol). Both are installed and I don’t think it would only not work sometimes if they were missing. I’m thinking of hopping to another distro haha I know it’s not arch’s fault, but this excuse is as good as any lmao





  • Yeah, Ubuntu is fine, I run Ubuntu myself. From my experience, this is one of the painful containers to set up haha But okay let’s roll with it. Personally, I did it with the “From GHCR/Docker Hub” option, and it took some tweaking. If you tried this option, where did you stop and what error did you get? Or do you want me to go step by step?

    PS. For a more complete guide on homeserver, docker and stuff I recommend Smart Home Beginner. That’s where I learned. You don’t need his “Auto Traefik” stuff tho, so just ignore it





  • Oh boy we’re going deep I guess haha.

    So an IP address is divided into four section separated by dots. 123.123.123.123. Each of those section can go from 0 to 255, so 0.0.0.0 to 255.255.255.255. Why this number? There is 256 numbers from 0 to 255, and 256 is the biggest number you can make out of 8 bits. (If you’re interested in binary, please look it up, this is already long haha) If every number between the . can be made out of 8 bits that means the whole IP address is 32 bits. It’s 32 bits cos that’s what was convenient when it was decided basically. Makes sense?

    Now, the subnets. Each network can be divided into sub networks or subnets. Subnets fall into 5 classes: ABCDE. D and E aren’t used as much so I don’t know much about them.

    Class A: Subnet mask is 255.0.0.0 Class B: Subnet mask is 255.255.0.0 Class C: Subnet mask is 255.255.255.0

    A subnet mask determines how many bits are reserved for the network, and how many bits are used for hosts (devices). Basically, each IP address is divided into a network part and a host part. Network part is used for identifying networks and how many you can make, while host part is used for identifying hosts/devices like your phone or PC or whatever and how many can be connected.

    In class A, with 255.0.0.0, the first number is reserved for the network, and the other 3 for the devices for example.

    In class A you have a small amount of possible subnets but a big number of devices, and the opposite in class C.

    The 24 after the slash is just a different way of saying 255.255.255.0, called CIDR notation. 255.0.0.0 is /8 and 255.255.255.0 is /16.

    So depending on the subnet class, what the numbers mean differs. Well except the port and CIDR subnet mask.

    All in all, all you need to know is that your router most likely has one subnet lol
