Fedora 33 : Can be better? part 017.
Today I will show you how Fedora distro Linux can be better in terms of the LXDE environment.
Fedora team come with Fedora LXDE on Spins, see this intro:
LXDE, the "Lightweight X11 Desktop Environment", is an extremely fast, performant, and energy-saving desktop environment. It maintained by an international community of developers and comes with a beautiful interface, multi-language support, standard keyboard shortcuts, and additional features like tabbed file browsing.
Fedora does not have a defined environment because multiple work environments can be set.
Today, I will show you how to use the LXDE environment with Fedora can be improved.
I often use a simple environment in Linux because:
- I have older hardware
- their simplicity allows me to make my personal settings to be more efficient;
Here are some examples of how we can improve the LXDE environment:
Using the ObConf tool
ObConf now easily installs new themes that use the .obt Openbox theme archive format for distribution.
[root@desk mythcat]# dnf search obconf
...
obconf.x86_64 : A graphical configuration editor for the Openbox window manager
[root@desk mythcat]# dnf install obconf.x86_64
Last metadata expiration check: 0:25:25 ago on Sat 13 Feb 2021 11:49:09 AM EET.
Package obconf-2.0.4-17.20150213git63ec47.fc33.x86_64 is already installed.
Dependencies resolved.
Nothing to do.
Complete!Windows open on the center screen.
You need to add this source code to the end of the file named lxde-rc.xml.
<application type="normal">
<position>
<x>center</x>
<y>center</y>
</position>
</application>Depending on the keyboard and configuration you can set key combinations for different functions such as the Fn key.
The Fn key is the wakeup key when the machine is suspended.
If anyone wants to map it to other functions, then that's okay.
Let's see one example with the lxde-rc.xml file.
<keybindkey="XF86AudioRaiseVolume">
<actionname="Execute">
<command>amixersetMaster5%+unmute</command></action>
</keybind>
<keybindkey="XF86AudioLowerVolume">
<actionname="Execute">
<command>amixersetMaster5%-unmute</command></action>
</keybind>
<keybindkey="XF86MonBrightnessDown">
<actionname="Execute">
<command>xbacklight-20</command>
<startupnotify><enabled>yes</enabled><name>Decreasescreenbrightness</name></startupnotify></action>
</keybind>
<keybindkey="XF86MonBrightnessUp">
<actionname="Execute">
<command>xbacklight+20</command>
<startupnotify><enabled>yes</enabled><name>Increasescreenbrightness</name></startupnotify></action>
</keybind>You can now run this command for the changes to take effect each time you edit the lxde-rc.xml file:
[mythcat@desk ~]$ openbox --reconfigureSettings for users and languages.
[mythcat@desk ~]$ lxappearance
[root@desk mythcat]# lxdm-config
[root@desk mythcat]# setxkbmap -layout "us,ro" -option "grp:alt_shift_toggle".In conclusion, there are enough settings that can be included by both the LXDE development team and Fedora team in a simpler way to configure the LXDE environment.
I would like to have in the LXDE environment from Fedora, the Fedora widget, the Fedora theme, Fedora Color.
The Fedora development team could effortlessly include its own utility to manage these settings for LXDE or other work environments.

Fedora 33 : Meson build system.
Meson is a build system that is designed to be as user-friendly as possible without sacrificing performance. The main tool for this is a custom language that the user uses to describe the structure of his build. The main design goals of this language has been simplicity, clarity and conciseness. Much inspiration was drawn from the Python programming language, which is considered very readable, even to people who have not programmed in Python before., see the official webpage.
Let's test with an simple example on Fedora 33 distro.
First step, install this tool with DNF tool.

Fedora 33 : Running Zeek - part 001.
Zeek is often used as a network analysis tool but can also be deployed as an IDS known as Intrusion Detection System.
The full documentation can be found on this website page.
Let's install this tool on Fedora 33 distro.

Complete!
[root@desk mythcat]# whereis zeek
zeek: /opt/zeek/bin/zeek
[root@desk mythcat]# whereis zeekctl
zeekctl: /opt/zeek/bin/zeekctl
I found this informations into the documentation area:
ZeekControl is an interactive shell for easily operating/managing Zeek installations on a single system or even across multiple systems in a traffic-monitoring cluster.
A Minimal Starting Configuration
These are the basic configuration changes to make for a minimal ZeekControl installation that will manage a single Zeek instance on the localhost:
- In $PREFIX/etc/node.cfg, set the right interface to monitor.
- In $PREFIX/etc/networks.cfg, comment out the default settings and add the networks that Zeek will consider local to the monitored environment.
- In $PREFIX/etc/zeekctl.cfg, change the MailTo email address to a desired recipient and the LogRotationInterval to a desired log archival frequency.
Next step is to configure and adjust your PATH environment variable:
[root@desk mythcat]# export PATH=/opt/zeek/bin:$PATH
[root@desk mythcat]# zeekctl
Welcome to ZeekControl 2.2.0
Type "help" for help.
...
Use install , start and diag commands on Zeek command line to check if the Zeek tool works fine.
If you received this error on diag command , then you need to set your network interface:
==== stderr.log
fatal error: problem with interface eth0 (pcap_error: SIOCGIFHWADDR: No such device (pcap_activate))Let's fix this error using the files configuration:
[root@desk mythcat]# updatedb
[root@desk mythcat]# locate node.cfg
/opt/zeek/etc/node.cfg
[root@desk mythcat]# vi /opt/zeek/etc/node.cfgI change the row with the interface= with my network interface.
You can find your interface with these commands:
[root@desk mythcat]# ip link show
1: lo: mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
...
[root@desk mythcat]# nmcli device status
DEVICE TYPE STATE CONNECTION
... Now I can run the zeekctl command an check if is all right.
And first issue reported by diag and zeekctl is this:
1612693272.168741 Reporter::WARNING Your interface is likely receiving invalid TCP and UDP checksums, most likely from NIC checksum offloading. By default, packets with invalid checksums are discarded by Zeek unless using the -C command-line option or toggling the 'ignore_checksums' variable. Alternatively, disable checksum offloading by the network adapter to ensure Zeek analyzes the actual checksums that are transmitted. /opt/zeek/share/zeek/base/misc/find-checksum-offloading.zeek, line 54
You can see this tool can provide good information for users.
Fedora 33 : C# and Google A.P.I .
In this tutorial, I will show you how to use C # with Google A.P.I. on Fedora Linux.
You can find more C # tutorials written by me on the web.
This tutorial was added here by me because it is used with Fedora 33 distro.
You will need to set an authentication key in your google account, see the credentials page.

Fedora 33 : Roblox and Wine.
Because I tried to install this platform, I will show you what works and what doesn't.
At this moment Roblox Player cannot be run with Wine.
I tested two ways to run it.
First is the roblox-linux-wrapper and the second is the direct way to install RobloxPlayerLauncher.exe.
The roblox-linux-wrapper works but you will get this error.
The install process is simple:

Fedora 33 : The new Wine 6.0.
The new released of Wine 6.0 comes with this intro:
The Wine team is proud to announce that the stable release of Wine 6.0
is now available.
This release represents a year of development effort and over 8,300
individual changes. It contains a large number of improvements that
are listed in the release notes below. The areas of major changes are:
- Core modules in PE format.
- Vulkan backend for WineD3D.
- DirectShow and Media Foundation support.
- Text console redesign.
...
About Wine:
Wine (originally an acronym for "Wine Is Not an Emulator") is a compatibility layer capable of running Windows applications on several POSIX-compliant operating systems, such as Linux, macOS, BSD. Instead of simulating internal Windows logic like a virtual machine or emulator, Wine translates Windows API calls into POSIX calls on-the-fly, eliminating the performance and memory penalties of other methods and allowing you to cleanly integrate Windows applications into your desktop.
I used the Wine repo to install easily this software:
[root@desk mythcat]# dnf config-manager --add-repo https://dl.winehq.org/wine-builds/fedora/33/winehq.repo

Fedora 33 : Create a simple GUI Button on Unity 3D.
It is very useful to create applications in the Fedora 33 Linux distribution with the Unity 3D game engine.
In today's tutorial, I will show you how to build the simplest GUI with C# and a dynamic button.
To create a button dynamically you need to use GUI.Button.
Open Unity 3D new project in your Fedora 33 distro.
Add a new Game Object by right click and select Create Empty.
Select Game Object use Add Component to add a New script and name it create_button.
Open it and add this source code:
using UnityEngine;
using UnityEngine.UI;
using System.Collections;
public class create_button : MonoBehaviour {
void OnGUI()
{
if (GUI.Button(new Rect(10, 10, 300, 20), "Test - Dynamically button"))
{
Debug.Log("Test button");
}
}
}If you run the Unity project you will see a basic Unity 3D button, see the next image:

Fedora 33 : Using the finch chat program.
Finch is a TUI (text user interface) IM client for Linux which uses libpurple.
This is very useful when you want to chat and don't have an environment to install Fedora on.
Finch is built using the ncurses toolkit, which is a library designed especially to built text user interfaces.
This program lets you sign on to Jabber, GoogleTalk, IRC, and other IM networks.
After this was built the Pidgin application.
Let's install it with the DNF tool:
[root@desk mythcat]# dnf install finch.x86_64
...
Installed:
finch-2.14.1-2.fc33.x86_64 libgnt-2.14.0-3.fc33.x86_64
Complete!You can find all information using the man command:
[mythcat@desk ~]$ man finch [mythcat@desk ~]$ finchAfter that, you can see the windows form for your account.
You can see one example with my IRC account:
If not you can select it by pressing the keys: Alt+A and select Accounts.
Use the Tab key and select Modify.
The new window form lets you set your account.
In the next image, you can see some settings for my IRC account.
Another important element is that this interface can be customized using the file named .gntrc.
Open it with your editor, I used vi editor:
[mythcat@desk ~]$ vi ~/.gntrcI make these changes to use the mouse:
[general]
mouse = 1Although the manual page says the mouse support is still experimental.
I install the GPM - a cut and paste utility and mouse server for virtual consoles.
[root@desk mythcat]# dnf install gpm.x86_64
...
[root@desk mythcat]# systemctl status gpm

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
haven't set the root password yet, you should just press enter here.
Enter current password for root (enter for none):
OK, successfully used password, moving on...
Setting the root password or using the unix_socket ensures that nobody
can log into the MariaDB root user without the proper authorisation.
You already have your root account protected, so you can safely answer 'n'.
Switch to unix_socket authentication [Y/n] n
... skipping.
You already have your root account protected, so you can safely answer 'n'.
Change the root password? [Y/n] n
... skipping.
By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.
Remove anonymous users? [Y/n] Y
... Success!
Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n] Y
... Success!
By default, MariaDB comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n] Y
- Dropping test database...
... Success!
- Removing privileges on test database...
... Success!
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n] Y
... Success!
Cleaning up...
All done! If you've completed all of the above steps, your MariaDB
installation should now be secure.
Thanks for using MariaDB![root@desk mythcat]# mysqladmin create mysite -u root -p
