When you use ssh with X forwarding, you might have noticed that you cannot execute programs that require 3D acceleration. That's where VirtualGL comes into play.

Proxmox PVE Host Config Backup Script

This script can be used to backup essential configuration files from the Proxmox Virtual Enivronment (PVE) host.

The script will create backups using tar with specified backup prefix and date and time stamp in the file name. Script will also delete backups that are older then number of days specified.

Create backup script file

To create backup script that will be executed every day we can create backup script in /etc/cron.daily/ folder. We need to make it writeable by root (creator) only, but readable and executable by everyone:

touch /etc/cron.daily/pvehost-backup

	set -g default-terminal "screen-256color"

	set -g prefix C-a

	#restore
	bind-key r source-file ~/.tmux.conf \; display-message "tmux.conf reloaded."

	#shrtcuts
	bind -n C-p send-keys "djptwm:024" \; send-keys "Enter" \;
	bind -n C-x send-keys "exit" \; send-keys "Enter" \;


	# Build tools:
	sudo apt-get install -y build-essential cmake

	# GUI (if you want to use GTK instead of Qt, replace 'qt5-default' with 'libgtkglext1-dev' and remove '-DWITH_QT=ON' option in CMake):
	sudo apt-get install -y libgtkglext1-dev libvtk6-dev

	# Media I/O:
	sudo apt-get install -y zlib1g-dev libjpeg-dev libwebp-dev libpng-dev libtiff5-dev libjasper-dev libopenexr-dev libgdal-dev
