Proxmox VE is a solution fit for adoption in an enterprise virtualization environment. It has a tight integration with KVM hypervisor and containers (LXC), software-defined storage and networking functionality all bundled in a single platform. The central user interface shipped in Proxmox VE has self-signed certificate, but with it you can run Virtual Machines, Containers, manage Networking and software-defined storage resources without touching command-line interface. In this article we shall discuss the process of securing your Proxmox server web console with Let’s Encrypt free SSL Certificate. For this guide, Proxmox VE should be on a public network with a valid DNS A record pointing to it. For the purpose of this guide, let’s consider DNS record pve.example.com, with an A record of 88.20.40.50. Login to your Proxmox web dashboard. Add ACME Account Click on your Datacenter > ACME > Add to add a new account. The ACME Issuer requires an account registered with the Automated Certificate Management Environment (ACME) Certificate Authority server. Click on Add to proceed. Input name for the account, valid email address and accept terms of service. Account registration process output: Confirm the account is now available for use after being added successfully. Adding ACME account using command line: pvenode acme account register Request Let’s Encrypt SSL Certificate for Proxmox VE Click on Proxmox hypervisor node, then navigate to the Certificates section. Select account you added earlier Click “Add” to add Proxmox VE domain name as configured in your DNS server. This can also be performed from CLI: pvenode config set --acme domains= Settings with the domain added and ACME account selected. Proceed to request for Let’s Encrypt SSL certificate using “Order Certificates Now” button. If everything is in order the process should be successful as seen in screenshot below. Confirm your new certificate under “Certificates” section. If you want to order for SSL certificate from command line instead, then run: pvenode acme cert order Reload Proxmox VE Web Console Reload your web browser for the new certificate to be loaded. If you expand HTTPS, you should get more details about the certificate in use. This validates our setup to be successful. We now have our Proxmox server using Let’s Encrypt SSL. If you encounter any challenges let us know through the comments section.

We can all agree Proxmox VE is such an amazing Virtualization solution for home users and corporate business application setups. There is no need for separate management tool in Proxmox since everything can be done through the web browser. A built-in HTML5 console is used to access the guest console. As an alternative, SPICE can be used. Proxmox Virtual Environment offers excellent command-line tools and REST API for third-party application integrations. By design, Proxmox comes with a single theme upon its installation. In this guide we shall cover the steps you’ll follow to install a custom Discord-like dark theme for the Proxmox Web UI. But first let’s look at the features of Proxmox Web Interface. Features of Proxmox VE Graphical User Interface Some of the features available on Proxmox VE Graphical User Interface are: Seamless integration and management of Proxmox VE clusters AJAX technologies for dynamic updates of resources Fast search-driven interface, capable of handling hundreds and probably thousands of VMs Secure access to all Virtual Machines and Containers via SSL encryption (https) Secure HTML5 console or SPICE Role based permission management for all objects (VMs, storages, nodes, etc.) Support for multiple authentication sources (e.g. local, MS ADS, LDAP, …) Two-Factor Authentication (OATH, Yubikey) Based on ExtJS 6.x JavaScript framework Install Discord-like dark theme on Proxmox VE We’ll use a dark theme for the Proxmox Web UI, inspired by Discord’s color scheme. The project is available on Github if you’re interested in code sources. In this theme, everything is dark, including the graphs, context menus and all in between. Before theme installation, the Proxmox VE graphical user interface (GUI) has a look shown in screenshot below. We will perform theme installation via the CLI utility. Login to your PVE node running Web UI, see our example below: $ ssh root@192.168.1.12 10:32:31 root@pve01 ~ → Install wget tool if not available on the node. sudo apt update && sudo apt install wget curl -y Use wget utility to download theme installation script. wget https://raw.githubusercontent.com/Weilbyte/PVEDiscordDark/master/PVEDiscordDark.sh Make the script executable and run it. chmod +x PVEDiscordDark.sh sudo ./PVEDiscordDark.sh install Installation process should complete in seconds. ✔ Backing up template file ✔ Downloading stylesheet ✔ Downloading patcher ✔ Applying changes to template file ✔ Downloading images (29/29) Theme installed. To see all script options run the command: $ ./PVEDiscordDark.sh -h Usage: ./PVEDiscordDark.sh [OPTIONS...] COMMAND Manages the PVEDiscordDark theme. -h --help Show this help -s --silent Silent mode Commands: status Check current theme status (returns 0 if installed, and 1 if not installed) install Install the theme uninstall Uninstall the theme update Update the theme (runs uninstall, then install) Exit status: 0 OK 1 Failure 2 Already installed, OR not installed (when using install/uninstall commands) This scripted installer relies on the /meta/supported and /meta/imagelist files being present in the repository. Below is new look on the login screen. Web interface overview page view with the new theme. The theme can be updated to new release with the command: $ sudo ./PVEDiscordDark.sh update ✔ Removing stylesheet ✔ Removing patcher ✔ Reverting changes to template file ✔ Removing images Theme uninstalled. ✔ Backing up template file ✔ Downloading stylesheet ✔ Downloading patcher ✔ Applying changes to template file ✔ Downloading images (29/29) Theme installed. Uninstall Discord-like dark theme on Proxmox VE If you want to uninstall the theme use the commands below to remove it and all its associated files. $ sudo ./PVEDiscordDark.sh uninstall

✔ Removing stylesheet ✔ Removing patcher ✔ Reverting changes to template file ✔ Removing images Theme uninstalled. Enjoy your new look on Proxmox VE GUI. We hope this guide was helpful.

Dnsmasq is an easy to configure and lightweight DHCP Server and DNS forwarder. Dnsmasq is designed primarily to provide DNS service and optionally, DHCP, in a small network setup. The DHCP server in Dnsmasq integrates with the DNS server seamlessly. The machines with IP addresses allocated by DHCP server appear in the DNS with names configured either in each host or in a central configuration file. Dnsmasq support dynamic and static DHCP leases. On top of stated features it has support for BOOTP/TFTP which can be used for network booting of diskless machines. Dnsmasq can be used in Proxmox virtualization platform to assign IP addresses dynamically or statically, and also to manage DNS. We’ll run Dnsmasq in one Proxmox hypervisor, with the service bound to specific network interface / bridge. Step 1: Install dnsmasq on Proxmox VE 6.x I’ll install dnsmasq in one Proxmox hypervisor from the default upstream repositories. sudo apt update sudo apt install dnsmasq Proceed to install dnsmasq on Proxmox VE 6.x Reading state information... Done The following additional packages will be installed: dns-root-data dnsmasq-base Suggested packages: resolvconf The following NEW packages will be installed: dns-root-data dnsmasq dnsmasq-base 0 upgraded, 3 newly installed, 0 to remove and 0 not upgraded. Need to get 463 kB of archives. After this operation, 1,027 kB of additional disk space will be used. Do you want to continue? [Y/n] y Also install dnsutils package which provides dig command: sudo apt install dnsutils -y Test your installation: $ dig computingpost.com @localhost nslookup computingpost.com localhost The DNS function in Dnsmasq is configured to forward all requests to your system’s default DNS settings as configured in /etc/resolv.conf file. Step 2: Configure DHCP Server using Dnsmasq After successful installation of Dnsmasq on your Proxmox server you can the start to configure DHCP service. sudo vim /etc/dnsmasq.conf Set domain for dnsmasq: domain=example.com Let dnsmasq know which ethernet interface it will use to listen for DHCP requests: #Around line 106 interface=vmbr1 # Or which to listen on by address (remember to include 127.0.0.1 if you use this.) #listen-address= Set DHCP server range of IP addresses to hand out. #around line 159 dhcp-range=192.168.50.50,192.168.50.200,12h Set default route supplied by dnsmasq: #around line 337 dhcp-option=vmbr1,3,192.168.50.1 #dhcp-option=eth0,3,192.168.50.1 Provide upstream DNS servers: #line 66 # You can use Google's open DNS servers server=8.8.8.8 server=8.8.4.4 Set path to a file for the DHCP lease database: dhcp-leasefile=/var/lib/misc/dnsmasq.leases Test your configurations: $ sudo dnsmasq --test dnsmasq: syntax check OK. Restart dnsmasq service: sudo systemctl restart dnsmasq sudo systemctl enable dnsmasq Step 3: Create a VM on the network with DHCP service Create a new Virtual Machine from Proxmox web console. Let’s give it a name and choose node where it will run. Select OS installation disc. Pick correct network (should be same as one used in dnsmasq DHCP configurations) Install the operating system and once completed reboot and check IP address if from DHCP. If the interface didn’t get IP address assigned by DHCP server automatically you can try manual request: sudo dhclient interface That marks the end of our article.
