This tutorial shows how to share your USB device, e.g., USB mouse/keyboard, USB drive, webcam, and speaker, in Ubuntu so you can access remotely from other computers/laptops. Linux Kernel includes a command line tool called USB/IP, allowing to share USB devices between computers with their full functionality. So, a computer can use remote USB devices as if they were directly attached. If you just want to share USB mouse & keyboard between computers, then Barrier is a good choice. But for webcam, usb drive, printer (through it usually has option to do the job), and other general USB devices, this tutorial will show you how.
This is a step by step guide shows how to enable Wake-on-LAN feature in Ubuntu, so you can wake it up from suspend, hibernation, or shutdown state remotely using another computer or mobile phone.
Wake on LAN, WoL in short, is a protocol allows computer to be turned on or waked up from sleep using network message. It’s based on AMD’s Magic Packet Technology, and also known as wake on WAN, remote wake-up, power on by LAN, and resume by LAN.

This is a step by step beginner’s guide shows how to disable IPv6 in Ubuntu 24.04 LTS with or without system restart.
IPv6 is the future of internet protocols. But for some reasons, such as compatibility with certain networks, testing purpose, or security concerns, or just because don’t use that thing, users may want to disable IPv6 in their machines.
Disabling IPv6 is generally safe. There may be small performance loss on some websites and services that are optimized for IPv6, though you can re-enable it at any time as you want.
OBS Studio, the popular free open-source live streaming software, announced new major 30.2.0 release a day ago.
The new release has some improvements for Linux support. They include native NVENC encoder interface for NVIDIA GPU hardware accelerated encoding, and NVENC AV1 support. And, Linux shared texture support to the NVENC encoder, QuickSync encoder, as well as VA-API encoder.
OBS Studio 30.2.0 also added multi-track video streaming support, aka Enhanced Broadcasting on Twitch.
To improve the experience for viewers with poor network conditions or those watching on older devices, the streaming service usually creates multiple video qualities of original high-quality source content.
Now, OBS Studio itself can produce multiple video qualities, though, it so far supports only Windows and requires NVIDIA GTX 900, GTX 10, or RTX 20 series GPU or newer or an AMD RX 6000 series GPU or newer. And, it will collect info, such as OBS version and audio/video settings, CPU, GPU, Memory, and OS info and set to the streaming service.
This simple tutorial shows how to easily turn your Ubuntu or Debian into home media server, so that you can listen to the music, watch photos and videos that are stored in Linux PC remotely using your mobile phones and/or smart TVs.
GNOME, the default desktop in Ubuntu and Fedora Workstation, has built-in option to enable this feature. It uses Rygel home media solution as backend.
It automatically transcode media to a format compatible with the client device. And, client machines that supports DLNA/UPnP, such as Sony PlayStation, Microsoft Xbox, smart TV, Android, iOS, can access them through the local network.

This is a step by step beginner’s guide shows how to install and set up a lightweight Socks5 proxy server in Ubuntu or Debian.
Due to poor network connection, I decided to set up a proxy server on my remote VPS for playing an online game. However, the tutorials on the web are mostly using Dante, which consumes too much RAM, and makes my cheap VPS server frequently run out of memory.
After digging around, I found a lightweight socks5 proxy server called Microsocks. And, here’s how to install & use it in Debian & Ubuntu.
This tutorial shows how to change the MAC Address, aka hardware address, for your network interface in Ubuntu 24.04. Though the title said for Ubuntu 24.04, it should work in all current Ubuntu releases, including Ubuntu 20.04 and Ubuntu 22.04.
MAC address, stands for Media Access Control address, is a unique identifier primarily assigned by device manufacturers. Therefore, it’s often referred to hardware address or physical address. However, many network interfaces support changing their MAC addresses. And, here’s how to do the trick in Ubuntu.
