  • How to Install and Use Xrdp Server (Remote Desktop) on Linux System

    The Xrdp server is the RDP tool (Microsoft Remote Desktop Protocol) for Linux distributions. You can install it on your Linux system to connect your server or desktop over the internet. The Xrdp server allows you to use the multi-channel connection through a graphical user interface (GUI). Besides these, the Xrdp server also allows you to connect and restart sessions if your connection gets lost. If you are a network engineer or a Linux system administrator, you can install the Xrdp server on your Linux system and access your server or desktop from anywhere over the internet. [...] If you are using a Linux server; probably, you might need to get a desktop environment installed on your system to use the Xrdp server on your machine. You can use either the Gnome DE or the Xfce desktop environment on your Linux server. Here, I am using a Gnome desktop environment on my Ubuntu machine. However, run the following command-lines given below to install your desired desktop environment on your server.

  • Petter Reinholdtsen: Latest Jami back in Debian Testing, and scriptable using dbus

    After a lot of hard work by its maintainer Alexandre Viau and others, the decentralized communication platform Jami (earlier known as Ring), managed to get its latest version into Debian Testing. Several of its dependencies has caused build and propagation problems, which all seem to be solved now. In addition to the fact that Jami is decentralized, similar to how bittorrent is decentralized, I first of all like how it is not connected to external IDs like phone numbers. This allow me to set up computers to send me notifications using Jami without having to find get a phone number for each computer. Automatic notification via Jami is also made trivial thanks to the provided client side API (as a DBus service). Here is my bourne shell script demonstrating how to let any system send a message to any Jami address. It will create a new identity before sending the message, if no Jami identity exist already...

  • PSI and Cgroup2

    In the comments on my post about Load Average Monitoring [1] an anonymous person recommended that I investigate PSI. As an aside, why do I get so many great comments anonymously? Don’t people want to get credit for having good ideas and learning about new technology before others? PSI is the Pressure Stall Information subsystem for Linux that is included in kernels 4.20 and above, if you want to use it in Debian then you need a kernel from Testing or Unstable (Bullseye has kernel 4.19). The place to start reading about PSI is the main Facebook page about it, it was originally developed at Facebook [2]. I am a little confused by the actual numbers I get out of PSI, while for the load average I can often see where they come from (EG have 2 processes each taking 100% of a core and the load average will be about 2) it’s difficult to work out where the PSI numbers come from. For my own use I decided to treat them as unscaled numbers that just indicate problems, higher number is worse and not worry too much about what the number really means.

  • How to Create and Manage Archive Files in Linux - Linux.com

    In a nutshell, an archive is a single file that contains a collection of other files and/or directories. Archive files are typically used for a transfer (locally or over the internet) or make a backup copy of a collection of files and directories which allow you to work with only one file (if compressed, it has a lower size than the sum of all files within it) instead of many. Likewise, archives are used for software application packaging. This single file can be easily compressed for ease of transfer while the files in the archive retain the structure and permissions of the original files.

  • H2 Net Card adds four 2.5 GbE ports to ODROID-H2/H2+ SBC

    ODROID-H2+ is already a cool single board computer with an Intel Gemini Lake Refresh processor, up to 32GB RAM, dual 2.5GbE networking, support for SATA and NVMe storage, dual 4K video output, and more. But in recent days, I’ve read people complaining recently announced WiFI 6 or WiFi 6E routers only had one 2.5 Gbps or 5 Gbps Ethernet jack and wanted all/more RJ45 connectors to be 2.5 GbE ports or greater. But if even the two 2.5GbE ports on ODROID-H2+ are not quite enough for your needs, Hardkernel H2 Net Card triples that amount by adding four extra 2.5 GbE to the x86 SBC. It also works on ODROID-H2, meaning you’d get the existing dual Gigabit Ethernet ports, plus the four 2.5GbE ports from the M.2 card.
