According to the FengOffice website

Feng Office is an integrated suite of software designed to help your organization run better. Stay connected to your customers, meet project deadlines, find information faster and grow your organization.

This is a tool that can be very useful in professional environments. We also have a paid version with professional support and a community version that we can use in smaller projects.

Install FengOffice on Debian 10

The installation of FengOffice is possible using a server that has MariaDB, PHP, and of course, a server like Apache.

1.- Install Apache, PHP 7.1, and MariaDB on Debian 10

So, it is necessary to install Apache, MariaDB, and PHP 7.1 which is the version that will not give us problems with FengOffice.

So, we have to add the repository to install PHP 7.1

wget https://packages.sury.org/php/apt.gpg
sudo apt-key add apt.gpg
echo "deb https://packages.sury.org/php/ $(lsb_release -sc) main" | sudo tee /etc/apt/sources.list.d/php7.list

And finally, install all the necessary packages:

sudo apt update
sudo apt install apache2 mariadb-server php7.1 php7.1-mysql php7.1-curl php7.1-json php7.1-cgi libapache2-mod-php7.1 php7.1-xmlrpc php7.1-gd php7.1-mbstring php7.1-common php7.1-soap php7.1-xml php7.1-intl php7.1-cli php7.1-ldap php7.1-readline php7.1-imap php7.1-tidy php7.1-recode php7.1-zip php7.1-sq unzip catdoc xpdf ghostscript imagemagick wkhtmltopdf

Don’t forget to configure MariaDB with the mysql_secure_installation script

mysql_secure_installation

Define the root password and answer the questions indicated.

2.- Creting the new Database for FengOffice

Now it is necessary to create a new database together with a new user using FengOffice.

Open the MariaDB shell:

sudo mysql -u root -p

And it creates the database as well as the user and assigns the corresponding permissions:

CREATE DATABASE fengdb;
GRANT ALL PRIVILEGES ON fengdb.* TO 'fenguser'@'localhost' IDENTIFIED BY 'fengpss';
FLUSH PRIVILEGES;
EXIT;

You can change the values of the database, the user, and the password on your own. The password must be strong enough.

3.- Configure PHP before using FengOffice

To ensure the highest possible stability, it is recommended to make some changes to PHP. More than anything else we will increase the resources it can consume.

So, in the files /etc/php/7.1/cli/php.ini and /etc/php/7.1/apache2/php.ini set the following values.

max_execution_time = 300
max_input_time = 300
memory_limit = 512M
html_errors = Off
post_max_size = 250M
upload_max_filesize = 200M

As you are using nano, a very quick way to do this is to press the CTRL + W keys to enable the search and make everything easier.

When you make your changes, close the editor and apply your changes:

sudo systemctl restart apache2

4.- Download FengOffice on Debian 10

Now we can download FengOffice without any problem

And after the download is done, you can decompress the file with the command unzip

unzip fengoffice.zip

Move the generated folder to the Apache root directory.

sudo mv fengoffice-3.7.0.5 /var/www/html/fengoffice

And assign the necessary permissions to the folder. Also, make Apache the owner of the folder.

sudo chown -R www-data:www-data /var/www/html/fengoffice
sudo chmod -R 777 /var/www/html/fengoffice

After this, create a new Virtualhost for FengOffice:

sudo nano /etc/apache2/sites-available/feng.conf

And add the following:

<VirtualHost *:80>
          ServerAdmin admin@your-server.com
          DocumentRoot /var/www/html/fengoffice
          ServerName your-server.com

         <Directory /var/www/html/fengoffice/>
               Options FollowSymlinks
               AllowOverride All
               Require all granted
         </Directory>

ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined

</VirtualHost>

Replace the ServerName and ServerAdmin values with your own.

Save the changes and close the file.

Then, activate the new Virtualhost as well as the rewrite modules and headers

sudo a2ensite feng.conf
sudo a2enmod rewrite headers

And apply the changes by restarting Apache

sudo systemctl restart apache2

5.- Secure the installation with Let’s Encrypt

If you are going to use FengOffice on a server that will be accessible from the Internet then you should use HTTPS

There is nothing better than Let’s Encrypt to generate certificates for your domain quickly and conveniently.

So, install the packages with the following command

sudo apt install certbot python-certbot-apache

Now create and add the certificate with the following command

sudo certbot --apache -d your-domain.com

Follow the instructions and at the end, you will be able to access it using HTTPS

6.- Install FengOffice on Debian 10

Now you can access https://your-domain and you will see the following screen:

Afterwards, the installer will verify that the whole system meets the requirements.

Then you have to type the values of the database we have created as well as the credentials of the new user.

Next, you will see a screen indicating that the installation was successful and then you will have to create the new user by clicking Finish.

Create the new admin user with the credentials you want.

Then you will see the login screen

And now yes the administration panel.

Enjoy it.

Conclusion

FengOffice is used by many companies worldwide as a practical solution to collaborative environments. This application is quite good and easy to install as we have noticed today

Wavemon is a CLI tool written in C and open source that provides information about our wifi hardware. The interesting thing about the tool is that it gives us detailed information about our hardware as well as the active wireless connection.

On the other hand, Wavemon is compatible with all hardware recognized by the Linux kernel. This means that if your wireless device is recognized and works well, you should have no problems with Wavemon.

Install Wavemon on Linux

Fortunately Wavemon is available on most Linux distributions through the official repositories. So installation should not be a problem.

If you use Debian, Ubuntu, Linux Mint or any derivative, just use the following command:

:~$ sudo apt install wavemon

On the contrary, if you use Manjaro, Arch Linux or other derivative, you only have to use pacman.

:~$ sudo pacman -S wavemon

If you use CentOS, the EPEL repository must be enabled and then installed.

In the case of fedora, if it is in the repositories and it is installed with the following command

:~$ sudo dnf install wavemon

However if you use another distribution, on the project’s Github site, there are instructions for compiling the program.

Monitoring WiFi with Wavemon is really easy

One of the main advantages of Wavemon is the great ease of use. Everything is visible. There are no tricks but everything is there.

Once you install it, you can run it from the terminal with the following command:

:~$ wavemon

As you can see in the image, there is a lot of useful information, perfectly displayed.

First of all, we have the interface information. There we will find the SSID of the active wifi connection.

We can also see the signal strength and quality. In my case, I am close to the wifi device so the quality is high.

Then, we will see a statistics section where we will see the sent and received packages.

In info we will obtain many more data like the time of connection, the frequency and the channel.

Finally, we will be able to see the mac address of our device as well as the public IP address.

As you can see, all easy and fast.

At the bottom we can access the other screens. If you press F2 or l you will see the following screen:

There you will see a histogram showing the signal level and strength of the network.

But Wavemon is flexible and has a preference screen:

And that’s how easy it is to use Wavemon.

If you want more information, you can check the wavemon man page in the terminal:

:~$ man wavemon

So, enjoy it.

According to the project’s website, Atop is “an ASCII full-screen performance monitor for Linux that is capable of reporting the activity of all processes”.

Likewise, Atop allows you to monitor in real time the consumption of memory, CPU, swap and other computer resources. And using the netatop kernel module you can monitor networks as well.

So, Atop stands out for being light, fast and presenting an easy to manipulate interface. It also has the following features:

• Resource consumption by all processes.
• Utilization of all relevant resources.
• Permanent logging of resource utilization.
• Highlight critical resources

And many more features.

So, let’s install it on OpenSUSE 15.1.

Install and use atop on OpenSUSE 15.1

Atop is located in the OpenSUSE monitoring repository which makes it fairly easy to install. But first we must add the repository.

So open a terminal session and run the following command:

:~$ sudo zypper ar http://download.opensuse.org/repositories/server:/monitoring/openSUSE_Leap_15.1/ monitoring

After it is added correctly, it has to be reprioritized so that we don’t have problems installing it.

:~$ sudo zypper mr -p 70 monitoring

After that, we will have to refresh all OpenSUSE repositories.

:~$ sudo zypper refresh

Remember that the first time you use this repository, it will ask you to accept the GPG key of the repository. To do this, press the a key.

Finally, install atop on OpenSUSE using the following command:

:~$ sudo zypper in atop

Now we can use it.

Basic use of atop on OpenSUSE 15.1

Remember that the application interface is only for the terminal, so to launch it you just need to use the atop command.

:~$ atop

So, this is the default screen.

As I said before, atop is very easy to use. You only need to type a key to activate its features or its different views. Of course, which are they? Well, by pressing the h key, we will enter the help screen that will show them.

There you will have everything you can do with atop. Everything very simple, for example, I’m going to try the statistics of memory consumption. To do this I press the m key.

So, enjoy it.

Conclusion

To monitor systems there are many different applications, but atop is consolidated as a fast and stable alternative to do it. It is highly recommended to have it at hand in servers and even in a personal computer.

TablePlus is a modern intuitive application that is for managing relational and non-relational databases. Its main advantage is that it is compatible with many database management systems including popular, MySQL, MariaDB, PostgreSQL or SQLite. But it also supports NoSQL databases such as Apache Cassandra and MongoDB. In addition, the team of developers promises that more will come.

I like the minimalist and modern design of the application that gives a sensation of being an application according to these times. However, the application is not free and you have to pay to use it.

On the other hand, the application has stable and consolidated versions for Windows and macOS but recently they have published an Alpha version for Linux. And the best thing is that these alphas are free and we will be able to try them.

So, let’s take a look.

Install TablePlus on Ubuntu

To install it in Ubuntu 18.04, you have to add the application repository. First, you have to add the GPG key to it.

:~$ wget -O - -q http://deb.tableplus.com/apt.tableplus.com.gpg.key | sudo apt-key add - 

Then, add the repository by creating a file called tableplus.list in /etc/apt/sources.list.d/ and add the following:

:~$ sudo nano /etc/apt/sources.list.d/tableplus.list

deb [arch=amd64] https://deb.tableplus.com/debian tableplus main

Save the changes and close the editor. I use the terminal a lot but you can create the file with another editor like gedit.

After that, refresh the APT cache and finally install Tableplus.

:~$ sudo apt update 
:~$ sudo apt install tableplus

Then, you can run it from the main menu.

A little look to this tool for Database management

As soon as you open it you will be able to configure a new connection to a database server. There you will have to configure the connection. You will also have the option to test the connection before starting it.

In my case, I have used an instance of MariaDB to test. By default, when you establish the connection, you see the following way:

On the left side, the list of tables and below you can switch between databases. If you select a table, the data will be shown like this:

As we can see, everything is very clean, tidy, modern. One of the characteristics of this client is that everything looks very integrated with the GTK system. I haven’t tried it with QT.

Thanks to the lower buttons, you will be able to verify the structure of the table very quickly.

Also, you can limit the number of results you get.

So this is a very small look at this application.

Remember it’s an alpha and the developers say there will be weekly updates so don’t forget to update your equipment.

Also, keep in mind that the application will gradually evolve but it is a good start. It has been fast, efficient and easy to use all this with a pretty nice interface.

For more information, I recommend you visit the application website.

So, that is it. Do not forget to share.

What is Zabbix?

Zabbix is a powerful tool for network monitoring. It is open-source and uses database handlers to process the data collected from your analyses.

There are too many features that make Zabbix a necessary tool in a network because with it the sysadmin can have detailed information about what happens in it. In addition, you can have real-time monitoring with their due reports.

Install Zabbix on Debian 10

The procedure for installing Zabbix is quite simple. On the other hand, we will work on the terminal installing and preparing the installation of Zabbix. Then, you will have to complete the process using the web browser.

In addition, all post will use the root user. To be the root user, open the terminal and run:

:~$ su

So, let us start.

1) Install LAMP Stack on Debian 10

Zabbix has a very friendly web interface to obtain the monitoring results. In this sense, as it is a web application, it is required to have installed LAMP on Debian 10.

So, you can read How to install LAMP on Debian 10?

Besides that, you have to install these PHP modules with this command:

:~# apt install php php php-mysql php-curl php-json php-cgi php-xml php-mbstring php-bcmath

So, we can continue.

2) Create the Zabbix database and the MariaDB user

Zabbix requires a database manager. But it also requires a database. Creating the database is simple, but it is recommended to create a user dedicated to it.

Enter the MariaDB console with the following command:

:~# mysql -u root -p

Then, create a new database and the new user.

> CREATE DATABASE zabbixdb;
> GRANT ALL ON zabbixdb.* TO 'zabbixuser'@'localhost' IDENTIFIED BY 'zabbixpss';
> FLUSH PRIVILEGES;
> exit;

That is all for MariaDB.

3) Add the Zabbix repository for Debian 10

A great advantage that Zabbix gives us is that it has a repository for Debian 10. So, all this makes the installation process even easier.

To add the repository, just download the DEB file provided by the project and install it.

:~# wget -c http://repo.zabbix.com/zabbix/4.0/debian/pool/main/z/zabbix-release/zabbix-release_4.0-2%2Bbuster_all.deb

Then, install it.

:~# dpkg -i zabbix-release_4.3-1+buster_all.deb

4) Install Zabbix on Debian 10 (I)

After the repository has been successfully added, it is necessary to update APT.

:~# apt update

Next, we can install the packages without problems with the following command:

:~# apt install zabbix-server-mysql zabbix-agent zabbix-frontend-php

Once Zabbix is installed, you need to start the default database that comes with the installation. The process is very simple, just use this command:

:~# zcat /usr/share/doc/zabbix-server-mysql/create.sql.gz | mysql -u zabbixuser -p zabbixdb

In order to make Zabbix configured correctly with MariaDB, it is necessary to change some parameters in its configuration.

To do this, edit the file /etc/zabbix/zabbix_server.conf

:~# nano /etc/zabbix/zabbix_server.conf

Then, modify the following parameters:

DBHost
DBName
DBUser
DBPassword

Of course, set the MariaDB parameters that you have configured.

Next, save the changes and close the file.

Finally, restart the services.

:~# systemctl restart apache2
:~# systemctl restart mariadb
:~# systemctl restart zabbix-server

5) Install Zabbix on Debian 10 (II)

Now you have to complete the installation using the web browser. Open it and go to your server http://server-ip/zabbix and you will see the following:

Next, the wizard will check for the prerequisites.

Now, you have to configure the DB connection.

Next, the server details.

Now, the installation summary.

If everything was OK, you will see this.

Then you can log in. The default user is admin and the password is zabbix. After that, you will see the dashboard.

Conclusion

Zabbix is one of those applications that you have to have on a server to control the entire network. especially when there are many nodes and it is necessary to know what is the performance of it. In this post, you have learned how to install it in Debian 10, Buster.

Please share this post with your friends and join our Telegram channel.

Ajenti is a system administration panel compatible with many of the Linux distributions that exist. It is written in Python and requires very few resources. So, it is a great tool if we want to monitor the status and services of our system with a nice graphical interface, responsive and very functional. Of course, it is open source, under the BSD license which makes its source code be studied by those who want.

On the other hand, the application has a very friendly front-end created with Angular.js. This makes it compatible with most current browsers.

So, let us install Ajenti on Ubuntu 18.04 or Linux Mint 19.

1. Upgrade the system

It is always a good idea to update your system to receive the latest security updates. With this, you will have a more robust system and ready for action.

:~$ sudo apt update && sudo apt upgrade

Now, with the updated system, it is possible to continue with the installation without problems.

2.- Install required packages and add the external repository

Before installing Ajenti in Ubuntu it is necessary to install two necessary packages to do it. The first one is wget that will help us to download a file to add the repository. So, let us do it.

:~$ sudo apt install wget

The other package we must install as a dependency is python-imaging.

:~$ wget http://security.ubuntu.com/ubuntu/pool/universe/p/pillow/python-imaging_4.1.1-3build2_all.deb
:~$ sudo dpkg -i python-imaging_4.1.1-3build2_all.deb

After that, it is necessary to add the GPG key from the Ajenti repository to further improve package security and integrity.

:~$ wget http://repo.ajenti.org/debian/key -O- | sudo apt-key add -

Then, run the following command to add the Ajenti repository to the system repository list.

:~$ echo "deb http://repo.ajenti.org/ng/debian main main ubuntu" | sudo tee /etc/apt/sources.list.d/ajenti.list

Finally, install Ajenti.

:~$ sudo apt update
:~$ sudo apt install ajenti

After that, you have to enable and start the service. You can also check the service status. To do it, run these commands.

:~$ sudo systemctl enable ajenti
:~$ sudo systemctl start ajenti
:~$ sudo systemctl status ajenti

Ajenti runs through the port 8000. So, if you are using a Firewall, remember to open that port.

So, you can open the web browser and go to http://SERVER_IP:8000.

3. Install Ajenti V Plugin

Ajenti V plugin is a set of plugins that are installed to Ajenti and increase its power. Thanks to this you will be able to manage MySQL or Apache and it is very useful. To do so, execute the following command:

:~$ sudo apt install ajenti-v ajenti-v-nginx ajenti-v-mysql ajenti-v-php7.2-fpm php7.2-mysql

So, restart Ajenti.

:~$ sudo systemctl restart ajenti

And go back to the web browser to log in. The user is root and the password is admin.

Now, you will see this screen. In it, you have the main info system.

After that, you can also see the plugins section.

You also have a utility that will allow you to use a small program of notes in the application.

So, you can also manage a MySQL instance.

Or you can manage the Firewall.

There is also a File manager utility.

So, that’s it. Enjoy Ajenti.
