Cockpit – Web GUI for Your Linux Servers

Cockpit gives you a GUI for your server, which can be accessed via a web browser. Cockpit makes it easy to start containers, administer storage, configure networks, inspect logs, and perform system tasks with a mouse.

You can think of Cockpit like a graphical “desktop interface”, but for individual servers.

To install Cockpit on Debian / Ubuntu use command:

sudo apt install cockpit

Default Cockpit web port is 9090, don’t forget to allow access to this port in your firewall.

With Cockpit you can easy get access to server terminal from your Web-browser:

Sound Blaster 16 WavEffects 4170

Sound Blaster 16 (June 1992), the successor to the Sound Blaster Pro, introduced CD-quality digital audio to the Sound Blaster line.

The Sound Blaster 16 WavEffects (CT4170) was released in 1997 as a cheaper and simpler redesign of the Sound Blaster 16. It came with Creative WaveSynth also bundled on Sound Blaster AWE64 Gold, a physical modeling software synthesizer developed by Seer Systems (led by Dave Smith), based on Sondius WaveGuide technology (developed at Stanford’s CCRMA).

The WavEffects line also supports CQM synthesis for Adlib/OPL compatibility.

How to install zsh on Debian, Ubuntu or Linux Mint

Zsh is a shell designed for interactive use, although it is also a powerful scripting language.

To install Zsh on Debian, Ubuntu or Linux Mint use command:

sudo apt install zsh

Next install “Oh My Zsh” – delightful, open source, community-driven framework for managing your Zsh configuration. Use command:

sh -c "$(curl -fsSL https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

If you want to change zsh theme go to: https://github.com/ohmyzsh/ohmyzsh/wiki/Themes

In order to enable a theme, set ZSH_THEME to the name of the theme in your ~/.zshrc

nano ~/.zshrc

Some themes need custom fonts, install it from git: https://github.com/powerline/fonts

git clone https://github.com/powerline/fonts.git --depth=1
cd fonts
./install.sh

Setup Proxmox cluster

1. First download official ISO image from Proxmox website: https://www.proxmox.com/

2. Write ISO image to USB flash drive using program Etcher: https://www.balena.io/etcher/

3. Boot PC from USB drive and install Proxmox. If you have two hard drives you can use ZFS file system to create RAID array.

Now log in to Proxmox admin panel using Web-browser: https://server-ip-address:8006

After installation we need to upgrade our system. Proxmox based on Debian GNU Linus and it use Debian repositories but in free version of Proxmox we will have an error when we try to upgrade. We need to disable enterprise Proxmox repositories. Open file /etc/apt/sources.list.d/pve-enterprise.list and comment with symbol # first line with enterprise Proxmox repository.

nano /etc/apt/sources.list.d/pve-enterprise.list

Then we can update packages list and upgrade our system:

apt update
apt upgrade

After installation let’s configure Local storage.

In admin panel go to Datacenter -> Storage, select local-lvm storage and click Remove

After that go to your Node -> Shell and write next commands:

lvremove /dev/pve/data
lvresize -l +100%FREE /dev/pve/root

And the last command to resize our local storage to 100% is:

resize2fs /dev/mapper/pve-root

Done, now we can use 100% of local storage, installed in our server. If you click on local storage you can see entire size of hard drive.

To remove the “You do not have a valid subscription for this server” popup message while logging in, run the command bellow:

sed -Ezi.bak "s/(Ext.Msg.show\(\{\s+title: gettext\('No valid sub)/void\(\{ \/\/\1/g" /usr/share/javascript/proxmox-widget-toolkit/proxmoxlib.js && systemctl restart pveproxy.service
