The journalctl command.

This is a good linux command for Linux maintenance.
First step is to read the documentation:
[root@localhost mythcat]# man journalctl
JOURNALCTL(1)                     journalctl                     JOURNALCTL(1)

NAME
       journalctl - Query the systemd journal

SYNOPSIS
       journalctl [OPTIONS...] [MATCHES...]

DESCRIPTION
       journalctl may be used to query the contents of the systemd(1) journal
       as written by systemd-journald.service(8).

       If called without parameters, it will show the full contents of the
       journal, starting with the oldest entry collected.

       If one or more match arguments are passed, the output is filtered
       accordingly. A match is in the format "FIELD=VALUE", e.g.
       "_SYSTEMD_UNIT=httpd.service", referring to the components of a
       structured journal entry. See systemd.journal-fields(7) for a list of
       well-known fields. If multiple matches are specified matching different
       fields, the log entries are filtered by both, i.e. the resulting output
       will show only entries matching all the specified matches of this kind.
       If two matches apply to the same field, then they are automatically
       matched as alternatives, i.e. the resulting output will show entries
       matching any of the specified matches for the same field. Finally, the
       character "+" may appear as a separate word between other terms on the
       command line. This causes all matches before and after to be combined
       in a disjunction (i.e. logical OR).
       ...
The self maintenance method is to vacuum the logs.
This help you with free space into your Linux OS.
For example: I got 3 Gigabytes of data in just 3 days.
# journalctl --vacuum-time=3d
Vacuuming done, freed 3.7G of archived journals on disk. To clean up this you can use the command into several ways:
  • by time
  • journalctl --vacuum-time=2d
  • retain only the past 500 MB
  • journalctl --vacuum-size=500M
As you know: The is an init system used in Linux distributions to bootstrap the user space and manage all processes subsequently. The journald daemon handles all of the messages produced by the kernel, initrd, services, etc. You can use the journalctl utility, which can be used to access and manipulate the data held within the journal. Let's start with some examples: How to see the configuration file for this process:
[root@localhost mythcat]# cat /etc/systemd/journald.conf
Also you can see the status of this service:
[root@localhost mythcat]# systemctl status  systemd-journald

Fedora 25: First test with clamav antivirus.

This is a short tutorial about how to use clamav antivirus on Fedora 25.
First you need to install it with this commands:
[root@localhost mythcat]# dnf install clamav.x86_64 
...

[root@localhost mythcat]# dnf install clamav-update.x86_64
...
Make settings into your /etc/freshclam.conf file. I used awk tool to show you my settings from /etc/freshclam.conf:
[root@localhost mythcat]# awk -F: '/^[^#]/ { print $1 }' /etc/freshclam.conf | uniq 
DatabaseDirectory /var/lib/clamav
UpdateLogFile /var/log/freshclam.log
LogFileMaxSize 2M
LogTime yes
LogVerbose yes
LogSyslog yes
LogFacility LOG_MAIL
LogRotate yes
DatabaseOwner clamupdate
DNSDatabaseInfo current.cvd.clamav.net
DatabaseMirror database.clamav.net
MaxAttempts 5
ScriptedUpdates yes
DetectionStatsCountry country-code
SafeBrowsing yes
Update the clamav antivirus with :
[root@localhost mythcat]# /usr/bin/freshclam

QEMU - Devil Linux on Fedora 25.

QEMU (short for Quick Emulator) is a free and open-source hosted hypervisor that performs hardware virtualization QEMU is a hosted virtual machine monitor. You can install this software using dnf tool.
dnf install qemu.x86_64 
You can use any iso image from internet to run and test your distro linux. Just use this command:
I tested with Devil Linux iso without network ( the main reason was the settings of Devil Linux distro).
qemu-system-x86_64 -boot d -cdrom ~/devil-linux-1.8.0-rc2-x86_64/bootcd.iso --enable-kvm -m 2048
 -netdev user,id=user.0
Some args of qemu tool:
- qemu-system-x86_64 is the option for x86 architecture (64 bit);
- boot and -d set options for booting and debug;
- the -cdrom option set the iso file path and file;
- the --enable-kvm enable Kernel Virtual Machine;
- the -m 2048 set memory;
- the -netdev user,id=user.0 that told qemu to use the user mode network stack which requires no administrator privilege to run;  
About QEMU VLAN.
QEMU networking uses a networking technology that is like VLAN. The QEMU forward packets to guest operating systems that are on the same VLAN. Examples with qemu-kvm options:
-net nic,model=virtio,vlan=0,macaddr=00:16:3e:00:01:01 
-net tap,vlan=0,script=/root/ifup-br0,downscript=/root/ifdown-br0 
-net nic,model=virtio,vlan=1,macaddr=00:16:3e:00:01:02 
-net tap,vlan=1,script=/root/ifup-br1,downscript=/root/ifdown-br1
- net nic command defines a network adapter in the guest operating system. - net tap command defines how QEMU configures the host. You can disabling networking entirely:
-net none

The ScreenFetch tool with Fedora 25 .

ScreenFetch is a System Information Tool designed primarily for Bash Shell but function with other shell environment as well. The tool is smart enough to auto-detect the Linux distribution you are using and generate the ASCII logo of the distribution with certain valuable information to the right of logo. 
Let's see my ScreenFetch:

Fedora: telnet game - BatMUD.

This is a good game if you have a telnet and internet connection.
Just open your terminal, run the telnet command and type o to open this: batmud.bat.org 23.
The game has a official website.
The team told us about this game:

What is BatMUD - scratching the surface 

One could go on and rant for hours and hours about the Game. If you're not familiar with BatMUD, don't worry - you won't even be after the first week of playing. The game's not easy, it was never intended to be. The first eyeful can be deceiving, especially as we live in the fully graphical world of commercially produced, hundred-million dollar budget behemoths. Our game, it's nothing like that; even though we tend to boast that it is more, and trust us - it is. A problem with the modern day games is that, eventually they become very dull or simply uninspiring. However, BatMUD's text-based approach it is different, somewhat to as reading a good book - it's all about your imagination. Hundreds of volunteer developers through the Decades have brought a special uniqueness to the Game, and new ones continue the Legacy to this day. We cater to almost everyone: the available options and playstyles are basically endless. It's Your Realm.
