Install OpenStack swift client only

To manage files in the OpenStack cloud you need the swift client. This is not so tiny python tool (a lot of dependencies), which offers by means of files (as files are objects for the OpenStack):

  • delete – Delete files, directories and sub-directories. Be careful with a simple command you can delete all your files at once. “Delete a container or objects within a container.”
  • download – Download files to your local storage. “Download objects from containers.”
  • list – List all files in the main directory (i.e. the container), cannot be listed files in sub-directories. The output will be a file with path per line or you can enable extended output to show file size, time modified, the type of the file and the full file path. “Lists the containers for the account or the objects for a container.”
  • post – Creates containers and updates metadata, could create seurity keys for temporary urls – “Updates meta information for the account, container, or object; creates containers if not present.”
  • copy – Copy files to a new place within a container or to a different container. “Copies object, optionally adds meta”
  • stat – Display information for files, container and your account. No information is available per directory. Most typically you will read the file length, the type and modifcation date. “Displays information for the account, container, or object”
  • upload – uploads files and whole directories in a container – “Uploads files or directories to the given container.”
  • capabilities – List the configuration options of your account like file size limits, file amount limits , limit requests per seconds and so on and which additional middleware your instance supports like bulk_delete, bulk_upload (the name are self-explainatory) – “List cluster capabilities.”
  • tempurl – Generate a temporary url for a file protected with time validity and a key – “Create a temporary URL.”
  • auth – Show your authentication token and storage url – “Display auth related environment variables.”

The text in the hyphens is from the swift help command. If you do not know what is a container with simple words these are the main sub-directories in your account if you use the list command without any argument (not adding a name after “list”):

myuser@myserver:~$ swift --os-username myusr --os-tenant-name myusr --os-password mypass --os-auth-url https://auth01.example.com:5000/v2.0 list
mycontainer1
anyname

The best way is to install the swift client from the package system of your Linux Distribution. The package system ensures the programs you install and upgrade are consistent within dependencies upgrades.

When you install this package “python-swiftclient” it depends on multiple python packages, which might be upgraded later, too, but the package system of a Linux distribution ensure the programs of python-swiftclient will work with them

. On the contrary, if you install it manually even with “pip” as it is offered in OpenStack site it is unsure what will happen and even your client program from “python-swiftclient” could stop working because of an upgraded dependancy library. Of course, the packages from the official package system could be a little bit older (but probably more stable) than the manual installs from the OpenStack official site. Still if you would like to install it with “pip” here you can check how you can do it: https://www.swiftstack.com/docs/integration/python-swiftclient.html

Install Fedora Workstation 30 (Gnome GUI)

This tutorial will show you the simple steps of installing a modern Linux Distribution like Fedora 30 Workstation with Gnome for the user graphical interface. First, we present the basic steps for installing the Operating system in addition to your present operating systems (here we also have Windows 10) and then you can see some screenshots of the installed system and the look and feel of it. We have other tutorials showing more screenshots of the installed and working Fedora 29 (Gnome and KDE plasma) – so you can decide which of them to try first – coming soon.

The Fedora 30 Workstation comes with

  • Xorg X server – 1.20.4 XWayland is used by default
  • GNOME (the GUI) – 3.32.1
  • linux kernel – 5.0.9

Check out our article about what software is included in comming soon.

The installation process is very similar to the old Fedora Workstation 27, Fedora Workstation 28 and Fedora Workstation 29, in fact the main difference is the creation of an user, which the setup is not responsible anymore, the creation of an user is done by the first boot after installation. Our system was pretty good – Asus X399 with AMD Ryzen Threadripper 1950X and NVIDIA 1080 Ti and the setup loaded successfully and there were no problems till the end.

We used the following ISO for the installation process:

https://download.fedoraproject.org/pub/fedora/linux/releases/30/Workstation/x86_64/iso/Fedora-Workstation-Live-x86_64-30-1.2.iso

It is a LIVE image so you can try it before installing. The easiest way is just to download the image and burn it to a DVD disk and then follow the installation below:

SCREENSHOT 1) Here is our “UEFI BIOS->Boot->Boot Override” and in most modern motherboard you can choose to override the default boot devices.

Choose the “UEFI: HL-DT-STDVDRAM…” to boot and install Fedora Workstation 30 with UEFI support. You should do this, because most of the new hardware like video cards would not work properly without being in UEFI mode.

Review of freshly installed Fedora 29 KDE Plasma Desktop (KDE GUI)

After the tutorial of Install Fedora 29 KDE Plasma Desktop this tutorial is mainly to see what to expect from a freshly installed Fedora 29 KDE Plasma Desktop – the look and feel of the new KDE GUI (version 5.13.5 of KDE Plasma).
Here you can find how to Install Fedora 29 KDE Plasma Desktop. Here it worth mentioning the included versions of KDE software for Fedora 29:
The Fedora 29 KDE Plasma Desktop comes with

  • KDE Plasma version: 5.13.5
  • KDE Frameworks version: 5.50.0
  • QT version: 5.11.1

The idea of this tutorial is just to see what to expect from Fedora 29 KDE Plasma – the look and feel of the GUI, the default installed programs and their look and how to do some basic steps with them, it is included also screenshots of the KDE settings program. Here you’ll find more than 140 screenshots and not so many text we do not want to turn this review of many text and version information and 3 meaningless screenshot, which you cannot see anything for the user interface, which these days is the primary goal of a Desktop system. You can expect more of this kind reviews in the future…

SCREENSHOT 1) Grub2 – Fedora 29 is selected by default.

The other Operating systems are Windows 10 and Ubuntu 16.04 LTS.

How to compile xmr-stak (2.5) under CentOS 6 for CPU mining cryptocurrencies in November 2018

In continuing our crypto series with xmr-stak we update the old article How to compile xmr-stak (2.4.5) under CentOS 7 for CPU mining cryptocurrencies with the new version 2.5 and tested the build procedure with the old CentOS 6.

In crypto mining it is important to have latest version of the mining software, because crypto world is super dynamic with thousands crypto currency and tens of algos, which ever month might be changed and updated!

Thanks to xmr-stak we can have one application capable of mining many different cryptocurrencies based on different algorithms. XMR-STAK is GPU and CPU miner, here we present only the CPU ability. Here are the steps you should do to install (in fact install dependencies and compile the miner) and to begin CPU mining:

STEP 1) Update your system and install the following dependencies

Because xmr-stak need a newer version of GNU GCC than the CentOS ships with you must install GNU GCC 5.1 at least. Because the latest versions have better optimizations for the processors we use here GNU GCC 7 from Software Collection repository – more information for this repository here: How to install new gcc and development tools under CentOS 7

[root@srv ~]# yum install -y centos-release-scl epel-release
[root@srv ~]# yum install -y cmake3 devtoolset-7-gcc* hwloc-devel libmicrohttpd-devel openssl openssl-devel make git screen

STEP 2) Compile the mining program xmr-stak

The installation process is very similar to the old Fedora Workstation 27 and Fedora Workstation 28, in fact the main difference is the creation of an user, which the setup is not responsible anymore, the creation of an user is done by the first boot after installation. Our system was pretty new – Asus X399 with AMD Ryzen Threadripper 1950X and NVIDIA 1080 Ti and the setup loaded successfully and there were no problems till the end.

It is a LIVE image so you can try it before installing. The easiest way is just to download the image and burn it to a DVD disk and then follow the installation below:

STEP 1) Here is our “UEFI BIOS->Boot->Boot Override” and in most modern motherboard you can choose to override the default boot devices.

Choose the “UEFI: HL-DT-STDVDRAM…” to boot and install Fedora Workstation 29 with UEFI support. You should do this, because most of the new hardware like video cards would not work properly without beeing in UEFI mode.

How to compile xmr-stak (2.4.5) under Fedora 28 for CPU mining cryptocurrencies

Thanks to xmr-stak we can have one application capable of mining many different cryptocurrencies based on different algorithms. XMR-STAK is GPU and CPU miner, here we present only the CPU ability under Fedora 28, not all setups have a good video GPU, but you can have a decent CPU, which could be used to mine! For example AMD Ryzen Threadripper 1950X has a good performance on my crypto algorithms, even a better performance than the GPU mining.
Here we use AMD Ryzen Threadripper 1950X, which has 12 cores and 32 threads. Our setup is ASUS ROG ZENITH EXTREME (X399 Chipset) motherboard with 32G (4x8G CROSSHAIR VI HERO) DIMM DDR4 Synchronous Unbuffered (Unregistered) 2133 MHz (0.5 ns) and AMD Ryzen Threadripper 1950X. It can do 1253.5 cryptonight_v7 hashes per second.
Here are the steps you should do to install (in fact install dependencies and compile the miner) and to begin CPU mining:

Update your system and install the needed dependencies
