  • DHCP (Dynamic Host Configuration Protocol ) is a communication protocol that is used to coordinate a network via a server. The server in most home cases is your internet router. It coordinates the network.

    Think of your network as a town with streets, every street has a unique name aka network address. So when a new device gets into the town it gets a unique address in a certain format, when requested by the clients. Mostly IPv4 i.e. 192.168.178.20.

    Second there are ports. Ports are the house numbers of the streets. So if two devices use the same IP they still can be differentiated by using different ports. To address a specific port you write it behind the IP, in our example 192.168.178.20:80. So we use port 80.

    To come back to the beginning the router coordinates the IP addresses and the ports from your internal network via DHCP and makes sure every device is accessible and no doubles.

    There is a lot more but very briefly this is it.












  • For all Proxmox users it looks like the new ZFS kernel module with the patch is included in the opt-in kernel 6.5.11-6-pve for now.

    The kernel 6.5 actually became the default in Proxmox 8.1, so a regular dist-upgrade should bring it in. Run “zpool --version” after rebooting and double check you get this:

    zfs-2.2.0-pve4 zfs-kmod-2.2.0-pve4

    As this versions are patched for bug.

    This is a repost from my suggestion some weeks ago:

    I went for the ASRock J5040 board, 16gb ram a 500gb m.2 as system using a PCI adapter , 2x4tb ironwolf as ZFS mirror pool, 350 W power supply all in the node 304 fractal case for 550 euro alltogether.

    Runs proxmox as hypervisor for VM or Container. 6 LXC running motioneye, plex, pyload with openvpn, syncthing, rclone cloud backup and openbookshelf.

    Typical power usage is around 20W

    That said it could also run on PicoPSU
