Fedora 37 : About DNF tool.

DNF's name tool comes from Dandified YUM.

You can find all about this tool in the Fedora documentation area.

As you know the YUM is in use on older systems and comes from Yellowdog Updater, Modified.

All of these tools need to have sudo that gives you administrative access to your system.

When you run the DNF tool this will checks for metadata automatically whenever you begin a system update or otherwise install software from repositories.

For this reason, the update and upgrade commands perform the same function.

Let's see the basic usage of the DNF tool:

Search a fedora package named FedoraPackage in the repositories.

sudo dnf search FedoraPackage

Install the FedoraPackage package if exist in the repository.

sudo dnf install FedoraPackage

If you want to uninstall the package FedoraPackage use this:

sudo dnf remove FedoraPackage

I can reinstall the package FedoraPackage

sudo dnf reinstall FedoraPackage -y

To automatically remove unneeded dependencies, use:

sudo dnf autoremove

The DNF can find out which package provides a particular file.

sudo dnf provides /etc/httpd/conf/httpd.conf

The detailed information of a package can be viewed with:

sudo dnf info httpd

The DNF history contains all actions that have been performed by the DNF command.

sudo dnf history

I can view further information about a transaction by specifying its ID:

sudo  dnf history info 13

I can undo this transaction if we want:

sudo dnf history undo 13 -y

I can redo with:

sudo dnf history redo 13 -y

The DNF will cache data to the /var/cache/dnf directory and I clean it with:

dnf clean all

I have the option to manually make the cache so that future actions will be quicker.

sudo time dnf makecache

The DNF tool gives me the ability to list all packages that are currently installed on our Linux system:

sudo dnf list installed

Packages that are related to each other may be grouped together into a package group.

sudo dnf grouplist

I can install it with this command:

sudo dnf groupinstall "Web Server" -y

I can check if an update is available

sudo dnf check-update

I can ignore an update for the FedoraPackage package with this command:

sudo dnf update -x FedoraPackage

I can use it for automatic tasks such as updating regularly via cron jobs.

sudo  dnf install dnf-automatic -y

I can install security only

sudo dnf updateinfo list sec

I can see displays information for enabled repositories only:

sudo dnf repolist

I can see all of the repositories

sudo dnf repolist all

Set update testing with:

sudo dnf config-manager --set-enable updates-testing

Disable update testing:

sudo dnf config-manager --set-disable updates-testing

You can list packages from a specified repository, for instance, FedoraPackage:

sudo dnf repository-packages FedoraPackage list

To display only a list of those packages available from the specified repository, add the available option.

sudo dnf repository-packages fedora list available

To display only a list of those packages installed from the specified repository, add the installed option

sudo dnf repository-packages fedora list installed

To add and enable a new repository like Grafana, run the following command.

Open a new file named grafana.repo:

sudo nano /etc/yum.repos.d/grafana.repo

Add this in the grafana.repo

[grafana]
name=grafana
baseurl=https://packages.grafana.com/oss/rpm
repo_gpgcheck=1
enabled=1
gpgcheck=1
gpgkey=https://packages.grafana.com/gpg.key
sslverify=1
sslcacert=/etc/pki/tls/certs/ca-bundle.crt

sudo dnf config-manager --add-repo /etc/yum.repos.d/grafana.repo

To enable the DNF repository

sudo dnf --enablerepo=grafana install grafana

To disable a DNF repository

sudo dnf --disablerepo=fedora-extras install grafana 

To permanently disable a particular repository

sudo dnf config-manager --set-disabled grafana

These are just a few basic ways to use the DNF utility.

Fedora 37 : First test with the Fedora Cinnamon spin.

The Fedora Cinnamon spin provides advanced innovative features and a traditional user experience.

I install this Fedora Spin from the official website.

I installed it again without an update.

It seemed faster than the old distro 36 with the Mate environment.

Here is a screenshot of Fedora 37 on the HP C6710b laptop. 

Fedora 36 : Rootkit Hunter tool.

rkhunter (Rootkit Hunter) is a Unix-based tool that scans for rootkits, backdoors and possible local exploits. It does this by comparing SHA-1 hashes of important files with known good ones in online databases, searching for default directories (of rootkits), wrong permissions, hidden files, suspicious strings in kernel modules, and special tests for Linux and FreeBSD..., see wikipedia .

You can find it on this website.

On Fedora 36 you can search and install with the DNF tool.

[root@fedora mythcat]# dnf search rkhunter

[root@fedora mythcat]# dnf install rkhunter.noarch
Last metadata expiration check: 3:39:00 ago on Sat 06 Aug 2022 10:35:34 AM EEST.

The first step is to upgrade it and then you can check the system.

[root@fedora mythcat]# rkhunter --propupd
[ Rootkit Hunter version 1.4.6 ]
File created: searched for 179 files, found 139

[root@fedora mythcat]# rkhunter --check
[ Rootkit Hunter version 1.4.6 ]

Checking system commands...

  Performing 'strings' command checks

...

The result can be found on the log file and you can set settings on the conf file type.

[root@fedora mythcat]# vi /var/log/rkhunter/rkhunter.log
[root@fedora mythcat]# vi /etc/rkhunter.conf

Fedora 36 : first steps with the Hy.

Hy is a dialect of the Lisp programming language designed to interact with Python by translating s-expressions into Python's abstract syntax tree (AST). Hy was introduced at Python Conference (PyCon) 2013 by Paul Tagliamonte.

This is quite similar to the old GIMP Script Fu that I've worked with in the past. The syntax assumes a join like tabs in HTML, only we'll use parentheses. I haven't studied in detail the implications it has with the python language, but it certainly wasn't invented for nothing.

First, you need to install it with the pip tool.

[mythcat@fedora ~]$ pip3 install hy --user
Collecting hy
...
Successfully built hy
Installing collected packages: funcparserlib, colorama, hy
Successfully installed colorama-0.4.5 funcparserlib-1.0.0 hy-0.24.0

The I test some examples:

[mythcat@fedora ~]$ hy
Hy 0.24.0 using CPython(main) 3.10.5 on Linux
=> (setv a 1)
=> "hello world"
"hello world"
=> (setv mylist [1 2 3])

=> (get mylist 0)
1
=> (defn greet [name]
...  "Hello "
...  (print "Hello " name))
=> (greet "mythcat")
Hello  mythcat

You can test it online with this online tool:

Fedora 36 : The zeek tool.

Zeek is a powerful network analysis framework that is much different from the typical IDS you may know.

Use the DNF tool to add repo for zeek tool:

[root@fedora home]# dnf config-manager --add-repo https://download.opensuse.org/repositories/security:zeek/Fedora_36/security:zeek.repo

Adding repo from: https://download.opensuse.org/repositories/security:zeek/Fedora_36/security:zeek.repo

Use DNF tool to install

Fedora 36 : Fill out this survey for a badge.

I've always liked Fedora distro because it applies a concept of interactivity between developers and users.

Even if not everything works, you can see the progress made from the older versions.

Today I completed my feedback in a survey requested by them and I also got a small badget for my effort.

You can find it on this webpage.

Fedora 36 : Inkscape 1.2 with Huion WH 1409 graphic tablet.

In this tutorial I will show you how to install and use the Huion WH 1409 graphics tablet with the new release of Inkscape 1.2 software.

You will need to use the DKMS feature of the kernel and the tablet-specific drivers.

Let's start with the following command to get the driver and show the files:

[root@fedora mythcat]# git clone https://github.com/DIGImend/digimend-kernel-drivers.git

digimend-debug    hid-rebind        hid-viewsonic.c
dkms.conf    hid-uclogic-core.c  Makefile

Let's create it using the command

[root@fedora digimend-kernel-drivers]# make dkms_install
...

dkms add .
Creating symlink /var/lib/dkms/digimend/11/source -> /usr/src/digimend-11
dkms build digimend/11

Building module:
cleaning build area...
make -j1 KERNELRELEASE=5.17.9-300.fc36.x86_64 KVERSION=5.17.9-300.fc36.x86_64...
...

Let's check and reboot.

[root@fedora digimend-kernel-drivers]# dkms status
digimend/11, 5.17.9-300.fc36.x86_64, x86_64: installed (original_module exists)
[root@fedora digimend-kernel-drivers]# reboot

After rebooting the diver must be activated and you will see that Linux responds to the movement of the tablet pen.

[root@fedora mythcat]# modprobe -r hid-kye hid-uclogic hid-viewsonic

Install the latest version of inkscape 1.2 using the DNF utility.

Start the inkscape software:

[mythcat@fedora ~]$ inkscape
static bool Inkscape::UI::Dialog::DialogContainer::recreate_dialogs_from_state(InkscapeWindow*, const Glib::KeyFile*): Key
file does not have group “Windows”
Gdk-Message: 15:09:10.534: Error flushing display: Broken pipe

It seems that inkscape does not detect and set the tablet if you use the settings of this software, but you can use the tablet with this software even if you do not set it.

Fedora 36 : Install django-hypergen and test it.

Today I test the last version of python version 3.11.0a7 with the Django-hypergen example.

The install process can be found on the GitHub page project.

You can see the full tutorial here.

News: Firefox 100 on Fedora distro.

This new release can download it and read more on the official webpage.

I tested today and as you can see this is working well:

Fedora 36 : Use the ykman tool - part 001.

You can see a full tutorial about how can install this linux tool for yubikey device on this tutorial.

The next command will program a random 38 character long static password to slot 1 on the device:

# ykman otp static 1 --generate --length 38 --force --keyboard-layout US

News: Fedora 36 beta released.

Fedora 36 beta was released and I tested it today.

First of all, Fedora 36 is still in pre-release mode and you should be careful to back up your data before upgrading it has a rollback option just in case.

I haven't seen any significant differences in browsing, and overall it seems faster.

The upgrade commands are the same but the installation process seems more complex.

# dnf upgrade --refresh
# dnf autoremove
# dnf install dnf-plugin-system-upgrade -y
# dnf system-upgrade download --releasever=36 --allowerasing
# dnf system-upgrade reboot
# cat /etc/os-release 

Let's fix the install process:

# dnf system-upgrade clean
# symlinks -r -d /usr 

This is ascreenshot take on my HP Compaq 6710b laptop, you can see the Workstation Edition Prerelease.

Fedora 35 : Kdenlive tool.

Note:

The new title of this blog is:About Fedora Linux distro

This was my first blog since blogspot.com and now blogger.com and I wrote my first articles and tutorials using the Linux operating system, especially Fedora distro.

Because I used it so much and it had an impact on my free time. Initially the title was generic "About me and my life" and I later kept it for S.E.O. and because it worked just as well as me.

The new title will not change the content at all and I hope it will come with new and good content.

---

Let's go back to today's tutorial article: installing kdenlive software.

Kdenlive is a powerful free and open source cross-platform video editing program made by the KDE community.

The last release was on Jan 7, 2022.

I use the DNF utility as follows:

Fedora 35 : Testing the new Django web framework version 4.0.1 with channels.

Today I tested in Fedora 35 the new version 4.0.1 of the Django framework and the channels package.

Channels augments Django to bring WebSocket, long-poll HTTP, task offloading, and other async support to your code, using familiar Django design patterns and a flexible underlying framework that lets you not only customize behaviors but also write support for your own protocols and needs. see the GitHub website.

The entire tutorial can be viewed on my blog about python programming language.

The result shows that it works with the admin webpage:

Fedora 35 : Roblox Player and Roblox Studio with Grapejuice.

In today's tutorial, I will show you how to install and play Roblox on the Linux Fedora 35 distribution using Grapejuice software.

The Grapejuice software installs protocol handlers to open games from the Roblox website and file handlers to open place files. It also provides a management interface for installing and launching Roblox.

For this, you will need to have a computer with the necessary hardware requirements for this online game.

I tested it on the old HP Compaq 6710b laptop on which I installed Fedora version 35 and it worked very hard.

Here are the Linux commands I used to install.

The Krita software runs well on the old HP Compaq 6710b, but I recommend better hardware because it is a software for graphic activities.

Don't worry about the message is a database change warning message.

Fedora 35 : Python and Flask-Mailing on Fedora.

First of all, a Merry Christmas to the users and the Fedora team. Python version 3.10.1 works very well on Fedore 35 and today I tested a packet called: Flask_Mailing.

Flask-Mailing adds SMTP mail sending to your Flask applications., see the Github repo.

Let's start with the installation of this packet with the pip utility.

[mythcat@fedora ~]$ pip install -U flask-mailing

I create a folder named ExempleFlask001:

[mythcat@fedora ~]$ mkdir ExempleFlask001
[mythcat@fedora ~]$ cd ExempleFlask001/
[mythcat@fedora ExempleFlask001]$ vi flask001.py

I created the simplest example to test through the import procedure and then read with the dir function, here is the source code:

from flask import Flask
from flask_mailing import Mail, Message

app = Flask(__name__)
@app.route("/")
def index():
    test = str(dir(Mail))
    return test
if __name__ == "__main__":
    app.run(debug=True)

The result of running the script on the command line:

[mythcat@fedora ExempleFlask001]$ python flask001.py
 * Serving Flask app 'flask001' (lazy loading)
