Proxmox supports multiple users, roles, groups, and authentication realms. This is essential for any shared or production environment, as well as keeping access limited and secure. Authentication Realms available in Proxmox Linux PAM-  uses the host OS users ...

Protecting your VMs and containers with regular backups is essential. Proxmox includes built-in backup and snapshot tools. Also, it's good idea to connect Proxmox Backup Server if you have an option of running another server. This way backups are stored off si...

Proxmox includes a built-in firewall that can be configured at the Datacenter, Node, and VM/Container level. Firewall Hierarchy Datacenter — rules that apply to all nodes in the cluster Node — rules specific to the Proxmox host itself VM/Container — rules sp...

This article covers how to create additional network bridges and set up an isolated network for your virtual machines — separating VM traffic from the Proxmox management interface. After installation, Proxmox creates one Linux bridge: vmbr0 — connected to you...

Shared storage allows multiple Proxmox nodes to access the same storage pool, enabling live migration of VMs and centralized backup storage. Also, if you have multiple devices clustered together, this can enable High Availability. Storage Types in Proxmox Dir...

A Proxmox cluster groups multiple Proxmox nodes together, enabling centralized management, live migration (moving VMs between nodes), and high availability. When second node is connected to a cluster, it will assume primary cluster roles and authentication. Pr...

High Availability (HA) ensures that critical VMs are automatically restarted on another node if the node they are running on fails. Prerequisites: A working cluster with at least 3 nodes Shared storage accessible by all nodes (so the VM disk can be accessed a...

This is a step-by-step document on how to connect a server directory to a Synology NAS using NFS. This guide assumes you have access to both the server and the Synology NAS. Prerequisites     Access to a server (Linux-based).    Access to a Synology NAS.    NF...

Search Engine Around this point in my homelab journey, I had the baseline established and was ready to focus on applications that would bring more meaning to my homelab and actually be of use. Throughout graduate school, a big focus of mine was cybersecurity a...

Security was at the forefront of this project — an idea that sparked a huge part of the build, and the topic I enjoyed most during graduate school. In the Foundation chapter, the focus was around access control at the firewall level, making sure that only spec...

Applications Once the foundation and all the supporting systems were in place, I thought — this is it, now I can actually start running applications. Up until that point, the only non-administrative thing running was my SearXNG search engine. The whole idea of...

When I first started running applications in my homelab, I was managing everything through the command line. Spinning up a container meant crafting a docker run command with all the right flags, ports, volumes, environment variables, network bridges, and hopin...

First lesson that every homelab journey eventually teaches, it's that it's not a matter of if something will break, it's when. Especially if you use used hardware from your old computer or cheap mini pc of ebay.  Having a solid backup strategy in place before ...
