Upgraded your server, but you need your old ZFS pools. How to import your olde files. Sometimes it's better to reinstall the Proxmox rather than trying to fix a broken system.
Networking
No open ports. Global access to your nodes.

Adding users to the sudo/doas/wheel group is a straightforward way to grant root-like access, especially in a multi-user environment where multiple users need administrative privileges. Is it wise – no, is it needed – sometimes. See also the Fail2ban section.
Tools
If you set up an Ubuntu server with the default US keyboard, you might like to change to your local keyboard. This is a quick note on how to do it.

This post will show the use of the Docker Socket Proxy with Portainer. It allows controlled and secure automation while still maintaining security. It's a reverse proxy that allows you to control what Docker API endpoints can be accessed by Docker clients such as Portainer, DIUN and Watchtower.

How do you make "Copy and Paste" work in your VM.
Docker
Container orchestration the easy way. Swarm mode is an advanced feature for container orchestration. Use Swarm mode if you intend to use Swarm as a production runtime environment. Docker Swarm mode is built into the Docker Engine. Docker Swarm mode is similar to K3s or even K8s, but it's lighter.

Sometimes it's a better to have an easy-to-use system rather than one with everything. We need a secure VM and that's why we run Proton OS. Using the recommendations of the KSPP (Kernel Self-Protection Project), the Photon OS Linux Kernel is secure from the start.
My new favorite. A Modern Docker Management GUI with a clean, intuitive design. The GUI includes: real-time monitoring, container management, image management, network configuration, volume management and resource visualization and the list goes on ...
One of the supporting pillars of virtualization is the use of Cloud-Init and Cloud Images. Setting up VMs is easy and fast. The process is easy to automate and adapt to CI/CD.
SmokePing is a deluxe latency measurement tool. It can measure, store and display latency, latency distribution and packet loss. SmokePing uses the RRDtool to maintain a long term data-store. It draws informative graphs of the state of each network connection to express up-to-the-minute information.
TrueCommand is a ZFS-aware solution, allowing you to set custom alerts on statistics like ARC usage or pool capacity, ensuring storage uptime and future planning. TrueCommand also identifies and pinpoints errors on drives or vdevs, saving valuable time when troubleshooting and resolving issues.
Running services on a PVE node is a perfect place to simulate networking. For the basic setup, we are to use SDN and OPNsense. Setting up a virtual or dedicated NIC as WAN and set up an SDN network for our VM/CT to use.
Proxmox Backup Server is flexible and can be installed on any device running Debian, a VM or a LXC. Here I show my Proxmox LXC setup. Having PBS on the PVE is making use of the large and fast SSD ZFS RAID 10 storage.
Before re-using any old disk, I do like to wipe them of data. Before removing the disk from the node, we wipe it clean. Now they are ready to store for later use or passed to a new owner with an old server.
The list of Intel Xeon E5-2600 (Broadwell) processors below includes all released models, and their most important specifications.
As I as many of you spend most of my time in a terminal, why not make it shine a little. As everyone know, ZSH is easy to rice, but you can almost as easy rice your BASH shell.
This script automatically assigns tags containing IP addresses to virtual machines and containers running in a Proxmox environment. It is an alternative to lxc-iptags but is more extensive and flexible in many ways.
You can make a new theme for Proxmox, and many have done so. The oldest came to PVE 6. The most feamose was "PVE Discord Dark", now we have some newer themes: Nord PVE, Solar PVE and new forks of PVE Discord Dark.
There are some instances when you need a Windows instance, but you don't need a full VM to do it. You can use a Docker Container for Windows XP – Windows 11 or one of the Windows Severs. Yes, this is possible, and it's a usable system.
This post is about installing Docker on Ubuntu 22.04 LTS. We also utilize the Dockge instead of Portainer. Dockge has some unique features and is well suited for use in a home lab. Portainer can do more, but Dockge is fine for now
