What is vnStat?

The best definition of Vnstat can be found on the project’s own website:

vnStat is a console-based network traffic monitor for Linux and BSD that keeps a log of network traffic for the selected interface(s). It uses the network interface statistics provided by the kernel as an information source. This means that vnStat won’t actually be sniffing any traffic and also ensures light use of system resources regardless of network traffic rate.

Therefore this tool is quite well known within the community and among sysadmins. It is quite simple to use and as you will see below it is easy to install.

Install vnStat on Debian 11 / 10

One of the fastest and most immediate ways to install vnStat on Debian 11 / 10 is to install it from the official repositories.

Although this is not the only way to get the program, it is the easiest method for newbies.

So, open a terminal or from an SSH session, install the security patches in the distribution:

sudo apt update
sudo apt upgrade

Next, you can install the vnStat package as follows:

sudo apt install vnstat

After it is installed, start the application service.

sudo systemctl start vnstat

This will complete the installation and you will be able to use it.

Install the latest version of vnStat on Debian 11 / 10

The previous method has a big problem and it is that the version that appears in the official repositories of Debian 11 / 10, is very outdated. So it is advisable to always install the latest version following these steps that I will describe.

First, install the packages needed to do the compilation, as well as some dependencies:

sudo apt install build-essential gcc make libsqlite3-dev

Then download the latest stable version, which at the time of writing this post, is 2.8.

wget https://humdi.net/vnstat/vnstat-2.8.tar.gz

Decompress the downloaded file

tar -xvzf vnstat-2.8.tar.gz

As a result of executing the above command, a folder called vnstat-2.8 will be generated which you will need to access and from there configure the package for compilation:

cd vnstat-2.8
./configure --prefix=/usr --sysconfdir=/etc

Now, compile the package and install it with this pair of commands:

sudo make
sudo make install

If everything went well, you will be able to run the vnstat command and display, for example, the installed version:

vnstat -v

Output:

vnStat 2.8 by Teemu Toivola <tst at iki dot fi>

Using the vnStat command

Before using the tool it is necessary to start the vnStat service. As we have installed it manually, there is no service installed so we have to create it.

Fortunately, to create it we will use the example file that comes with the code we have just compiled.

sudo cp -v examples/systemd/vnstat.service /etc/systemd/system/

Refresh the list of services

sudo systemctl daemon-reload

And now yes, enable it so it can start with the system and start the service

sudo systemctl enable vnstat
sudo systemctl start vnstat

And check the status of the service

sudo systemctl status vnstat

After waiting a few minutes, you can start using it.

vnstat

By default, it takes the active interface, but you can change it:

vnstat -i [interface]

When an interface is monitored, a new database with logs is created. You can delete it and reset the statistics.

sudo vnstat -i [interface] --remove --force

In this case, you have to specify the interface to monitor.

Enjoy it.

Conclusion

So now you know how to install and use vnStat on Debian 11 / 10 This command although simple allows you to find answers to the operation of a network interface and to know if the behavior is as expected…

What is Composer?

Composer is a project dependency manager for PHP programming. That means that it allows us to manage, i.e. specify, download, and keep up to date, the software packages or dependencies on which our PHP project is based.

The reason for using it is that when you develop a PHP application it requires functionality that is not in the default PHP libraries. That is, you have to add others for your project to work or to be able to be carried out.

So, when you start the project you have to go to the page of each of the software components that you want to use, download them, copy them to the folder of your project. This is a bit torturous because at some point these libraries will be updated and then you have to start this process all over again.

Composer was born to avoid this. Because just by defining the right dependencies, Composer will download them and add them to your project in a matter of seconds. And if they are updated, it only takes a minimal effort or command to update them. All without wasting time and in an orderly fashion.

So, let’s get started.

Install PHP Composer on Debian 11

As we can guess, one of the main requirements is to have PHP installed on the system. This shouldn’t be a problem because PHP is present in the Debian 11 repositories and is quite lightweight.

So, open a terminal and as usual update the distribution.

sudo apt update
sudo apt upgrade

Then, you can install PHP in case you don’t have it.

sudo apt install php

Note: If you don’t have sudo available then you have to run these commands as root. Also, you can enable it by reading our post about it.

Now to install Composer on the system, you have to run this single command

php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"

This command downloads and “compiles” the Composer installer for us.

Then install it in a directory that is in our PATH so that we can use it throughout the system. Also, you have to give it run permissions.

sudo php composer-setup.php --install-dir=/usr/local/bin --filename=composer
sudo chmod +x /usr/local/bin/composer

Then, verify the installed version by running

composer --version
composer version 2.1.8 2021-09-15 13:55:14

Using PHP Composer on Debian 11

Before using Composer it is always advisable to upgrade to the latest version. This process can be done by running

composer self-update

If you already have the latest stable version, you will get an output screen like this

You are already using the latest available Composer version 2.1.8 (stable channel)

Composer works with a file called composer.json which is where the project dependencies are stored. To add one you can visit packagist to find one you need.

For example, I will add sebastian/comparator with the command

composer require sebastian/comparator

Just like that, Composer recognizes the dependency, downloads it along with its dependencies, and installs them for our project that we just need to use. And so on with each of the dependencies you need.

To update the versions of the dependencies of your project run

composer update

Or you can update a single one

composer update sebastian/comparator

Also, you can update several at once.

To remove a dependency, just run

composer remove sebastian/comparator

So you can use Composer on Debian 11 in a basic but useful way.

Conclusion

In this post, we have covered the installation of PHP Composer on Debian 11 and a small introduction to its particular usage. This tool has become indispensable for many developers so it is not surprising that it is popular.

The post Install PHP Composer on Debian 11 appeared first on Linux Windows and android Tutorials.

Go is an open-source (BSD license) programming language that was born with the objective of allowing the creation of efficient and easily distributable applications. So, it has binaries for Windows, Mac OS and of course, for Linux.

So, in this post, I will install it and create a “Hello World” file for the test.

Download and install Go Language on Debian 11 /10

Go Language is cross-platform which makes it available for Linux. However, first you have to download the binaries from the project website. But we will use the terminal that is faster and more efficient.

First, make sure you have wget installed on your computer.

:~$ sudo apt install wget

Then proceed to download Go Language. At the time of writing this post, the latest stable version is 1.17

:~$ wget -c https://golang.org/dl/go1.17.linux-amd64.tar.gz -O go.tar.gz

Then, decompress it.

:~$ tar xvf go.tar.gz

Now you have to change the folder permissions. Besides moving it to another location like /usr/local/.

:~$ sudo chown -R root:root go
:~$ sudo mv go /usr/local

Then, it is necessary to make some modifications to the user’s bash profile in order to use Go. Open the configuration file and add the following:

:~$ sudo nano ~/.profile

export GOROOT=/usr/local/go    
export GOPATH=$HOME/work/
export PATH=$GOPATH/bin:$GOROOT/bin:$PATH

Save the changes (CTRL + O) and close the file (CTRL + X).

With this, Go is ready for work. You can check it by showing the version of the program.

:~$ go version

Now with a “hello world” we’ll see that everything works.

Testing the installation

As I said before, the best way to test the installation is to run a real code. For this, we will use the typical “Hello World”.

First, we’ll create the directory structure. In our Home, we will create a folder for the project called work. Inside a folder called src where the source code files will go. In it, a folder called hello and inside the file hello.go. Something like this is the directory structure. The folders work and hello can be called differently.

:~$ mkdir -p $HOME/work/src/hello

Now, create the Go file and add the following:

:~$ nano ~/work/src/hello/hello.go

package main 
 import "fmt"
 func main() {
 fmt.Printf("hello, world\n")
 }

Again, save the changes and close the file.

:~$ go build hello
:~$ go install hello
:~$ hello

So, enjoy it.

Conclusion

GO is a very popular language and every day it is more and more popular. It’s simple but very powerful, besides being open source. As you have seen, its installation is really simple.

So, Git?

If you are starting to develop applications you may not know that Git is a free, open-source version control system and that it is perhaps the best. Many developers rely on it to control the versions of their applications. By versions, we mean those in development.

Using Git you can control and separate development in each of those development branches. So the changes of one do not affect the others.

Read Introduction to the Git branches.

In this way, it is good practice to develop applications using a version control system as support.

Install Git on Debian 11 / 10

Debian 10 is one of the few distributions that have such complete package repositories. So, presumably, there is some Git in the official repositories.

However, it is also a good idea, to know how to install Git differently in case we need it. This way is compiling the source code of Git and get the latest stable version. In this tutorial, I will teach you how to do it both ways.

1) Using the official repository on Debian 11 / 10

Debian 11 / 10 include Git in the official repositories. Using this option, the installation is quite easy, and just open a terminal session and run the following command:

:~$ sudo apt install git

Or, if you do not have sudo, please read How to enable sudo on Debian 11/10?

Then, you can check the installed version.

:~$ git --version
git version 2.30.2

Now, you can use it.

2) Building the Git source code

Compiling the Git source code is the best way to get the latest version. All this in a safe way because it will not be compiled by third parties.

The process is simple but requires a few extra steps. So let us get started.

First, install the necessary programs to make the compilation:

:~$ sudo apt install build-essential make libssl-dev libghc-zlib-dev libcurl4-gnutls-dev libexpat1-dev gettext unzip

Now, we can download the source code.

:~$ cd /tmp/
:~$ wget https://mirrors.edge.kernel.org/pub/software/scm/git/git-2.33.0.tar.gz

Next, decompress it and access to the folder.

:~$ tar xvfz git-2.33.0.tar.gz
:~$ cd git-2.33.0

Now, you can start the compilation by running the following commands:

:~$ sudo make prefix=/usr/local all
:~$ sudo make prefix=/usr/local install

Next, check the installed version.

:~$ git --version

And that is it. You can start to use Git.

Conclusion

Git is one of those applications that every developer must be able to manage to improve their workflow. Therefore, it is important to install it in Debian 10 and two ways have been shown to achieve this. One of them is using the package available in the official repositories and the other is compiling the source code.

Microweber is a compact and quite complete CMS that allows us to deploy our blog or website quickly and easily. In addition to this, it allows us to manage it from a comfortable web interface where you can use a graphical editor to create the site.

With Microweber you can expect everything that a CMS can do, create, manage a website. Ideal for blogging or virtual stores, Microweber is a CMS to take into account.

Install Microweber CMS on Debian 10

Install LAMP on Debian 10

Microweber is a CMS that relies on PHP and a database manager like MariaDB. So we have to install the LAMP on Debian 10 stack.

However, the latest version of Microweber requires at least PHP 7.3 so we have to install PHP 8 on Debian 10.

Within the PHP modules that you have to install, you can’t miss these and other necessary packages.

php8.0 libapache2-mod-php php-common php-mbstring php-xmlrpc php-soap php-mysql php-gd php-xml php-cli php-zip php-curl unzip wget

Creating a new database and user

It would be best to create the database for Microweber CMS ourselves. Also, we will have to create a dedicated user for security reasons.

Open the MariaDB shell

sudo mysql -u root -p

Create the new database:

CREATE DATABASE microweberdb;

The database name can be whatever you want. Now create the user along with the password.

GRANT ALL PRIVILEGES ON microweberdb.* TO 'microweberuser'@'localhost' IDENTIFIED BY 'microweberpss';
FLUSH PRIVILEGES;

You can use any other username and password you want.

Now exit the shell

exit;

Now we can continue.

Download and install Microweber CMS on Debian 10

Now we can download and install Microweber. So, do it from the /tmp/ folder and using the command wget.

cd /tmp/
wget https://microweber.com/download.php -O microweber-latest.zip

2021-07-29 18:09:18 (87.5 MB/s) - ‘microweber-latest.zip’ saved [162704055/162704055]

Now create a folder in the Apache root directory where we will unzip the downloaded file.

sudo mkdir /var/www/html/microweber
sudo unzip microweber-latest.zip -d /var/www/html/microweber

Now make the folder belong to Apache and have the proper permissions.

sudo chown -R www-data:www-data /var/www/html/microweber/
sudo chmod -R 755 /var/www/html/microweber/

Then it is convenient to create a new virtualhost for Apache to manage the site properly.

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

Add the following:

<VirtualHost *:80>
  ServerName blog.osradar.test
  DocumentRoot /var/www/html/microweber/
 
  <Directory />
    Options FollowSymLinks
    AllowOverride All
  </Directory>
 
  <Directory /var/www/html/microweber/>
    Options FollowSymLinks MultiViews
    AllowOverride All
    Order allow,deny
    allow from all
  </Directory>

  ErrorLog ${APACHE_LOG_DIR}/microweber_error.log
  CustomLog ${APACHE_LOG_DIR}/microweber_access.log combined

</VirtualHost>

Remember to change the ServerName value to your domain. Save the changes and close the editor.

Enable the new configuration and the Apache rewrite module.

sudo a2ensite microweber
sudo a2enmod rewrite

Apply the changes by restarting Apache.

sudo systemctl restart apache2

Optional: Installing Certbot and the Let’s Encrypt certificates

Normally this site would be on the Internet which means that we have to use all possible security. So, we should install the Let’s Encrypt certificates to enable HTTPS.

So, install Certbot and its Apache plugin.

sudo apt install certbot python3-certbot-apache

Then, generate the certificates as follows

sudo certbot --apache --d [your-domain]

Enter your email address and accept the license terms and then restart Apache.

Installing Microweber using the web interface

Now open your web browser and go to https://your-domain and you will see a screen where you can customize the installation.

First, configure the database.

Below, you can configure the layout

And at the end, you can create the Microweber admin user.

So, enjoy it. Now you can start with the work of creating your website.

Conclusion

WordPress dominates the CMS industry but that does not indicate that there is real competition to offer better services. So, now you know how to install Microweber CMS and if you give it a try I am sure you will not be disappointed.

According to the Wildfly website:

WildFly is a flexible, lightweight, managed application runtime that helps you build amazing applications.

Being Java-based, it is compatible with many operating systems such as Linux, macOS, and Windows. In addition to this, it is open source which can help us with licensing issues.

So, now you will learn how to install it on a Debian 10 server or your computer for development.

Install Wildfly on Debian 10

Before we start, open a terminal and update Debian 10. In this post, we will use sudo if you don’t know how to enable it in Debian, we tell you in this post.

sudo apt update
sudo apt upgrade

Now it is time to install Java if you don’t have it on your system.

It is recommended to create a new user and group for Wildfly so that it does not interfere with the others. First, create a group like this

sudo groupadd -r wildfly

Now create the user:

sudo useradd -r -g wildfly -d /opt/wildfly -s /sbin/nologin wildfly

From the previous command, we can deduce that you will not be able to log in but you will have permission over the directory /opt/wildfly.

Now yes, from the /tmp folder, you can download Wildlfly

cd /tmp/

At the time of writing this post, the latest stable version of Wildfly is 24.0.0 so this command will change when a new version is released.

Then, decompress it

sudo tar xfv wildfly-24.0.0.Final.tar.gz -C /opt/

Make a symbolic link from the folder to another folder with an easier-to-remember name.

sudo ln -s /opt/wildfly-24.0.0.Final/ /opt/wildfly

Make the user wildfly the owner of the folder.

sudo chown -RH wildfly: /opt/wildfly

Configuring WildFly on Debian 10

By default, the package we have downloaded includes a configuration file that we have to enable. To do this, create a folder called wildfly in the /etc/ path.

sudo mkdir -p /etc/wildfly

And to enable the default Wildfly configuration, copy the example file to this directory.

sudo cp /opt/wildfly/docs/contrib/scripts/systemd/wildfly.conf /etc/wildfly/

Also, copy the startup script into the bin folder of the dedicated Wildfly folder.

sudo cp /opt/wildfly/docs/contrib/scripts/systemd/systemd/launch.sh /opt/wildfly/bin/

After this, assign run permissions to the script.

sudo sh -c 'chmod +x /opt/wildfly/bin/*.sh'

To start, restart and stop running Wildfly then it is best to do it via systemd, and then we have to create a new service for it. Fortunately, the downloaded package includes one so we have to copy it to the directory where the service configurations are hosted.

sudo cp /opt/wildfly/docs/contrib/scripts/systemd/wildfly.service /etc/systemd/system/

Now, refresh the list of services

sudo systemctl daemon-reload

And start the service

sudo systemctl start wildfly

Also, you can check the service for any errors.

sudo systemctl status wildfly

All that remains is to create the user with administrative permissions. To do this, run a script called add-user.sh.

After entering the username, and answering a few more questions, you will be assigned a password.

To represent the user add the following to the server-identities definition <secret value="YW5nZWxv" />

This way, you can open your web browser and visit http://localhost:8080 or if you installed on a server http://your-server:8080 and see this screen.

So, Wildfly is correctly installed.

Optional: Enable the administrative panel remotely

The administrative panel can be accessed from http://localhost:9990/console but if you installed Wildfly on a remote server, this will not work because, by default, this feature is disabled remotely.

So, you can enable it. To do this, edit the Wildfly configuration file

sudo nano /etc/wildfly/wildfly.conf

And add the following line at the end.

WILDFLY_CONSOLE_BIND=0.0.0.0.0

Save the changes and close the editor.

Now edit the WildFly startup script

sudo nano /opt/wildfly/bin/launch.sh

And replace the lines inside the second if that start with $WILDFLY_HOME with the following lines

$WILDFLY_HOME/bin/domain.sh -c $2 -b $3 -bmanagement $4
else
$WILDFLY_HOME/bin/standalone.sh -c $2 -b $3 -bmanagement $4

Save the changes and close the editor.

After this, you need to modify something in the file that manages the Wildfly service.

sudo nano /etc/systemd/system/wildfly.service

Change the ExecStart line to this one

ExecStart=/opt/wildfly/bin/launch.sh $WILDFLY_MODE $WILDFLY_CONFIG $WILDFLY_BIND $WILDFLY_CONSOLE_BIND $WILDFLY_CONSOLE_BIND

Refresh all daemons and restart the service.

sudo systemctl daemon-reload
sudo systemctl restart wildfly

You will now be able to remotely access your configuration panel.

Conclusion

Developing Java applications requires tools to help with the process. In this case, we have presented you with one that allows you to set up a JavaEE application server, and with Wildfly’s extensive experience we will have mature and production-ready software.

Enjoy it.

First of all, it is important to remember that it is IRC. Internet Relay Chat is a real-time communications protocol. Using IRC, users should not establish communication beforehand, so that all users on a channel can communicate with each other, even if they have had no previous contact. Widely used for discussions and technical support of many open source projects.

Install Inspircd on Debian 10

The first thing to do is to connect to the server via SSH. After that, upgrading the system is always a good option.

sudo apt update
sudo apt upgrade

With the system upgraded, we can start the installation of Inspircd on Debian 10. Fortunately, the package is in the official Debian 10 repositories so to install it, just run

sudo apt install inspircd
Reading package lists… Done

 Need to get 1,848 kB of archives.
 After this operation, 11.8 MB of additional disk space will be used.
 Do you want to continue? [Y/n]

This way, we will be able to use it and configure it for our instance.

Configuring Inspircd on Debian 10

The program as such is installed, but before using it we have to configure it.

First, on our system, we have to open ports 22 and 6667 where the application works.

Then, we have to examine the /etc/inspircd/inspircd.conf file which is where all the application configuration resides. It is a long file, but very well structured so we should have no problems editing it.

Before making any changes, make a backup of it.

sudo cp /etc/inspircd/inspircd.conf /etc/inspircd/inspircd.conf.bak

Now, yes, we can edit it.

sudo nano /etc/inspircd/inspircd.conf

In the server tab you have to configure the basics of the instance. In our chaos, we have left it as follows.

<server name="osradatest.ga"
    description="Example IRC Server"
    id="1AB"
    network="The osradar net">

Replace the name value with your domain and network with your network name. Set a description and leave the value of id as is.

Now in the admin tag create the admin user. Set a name, nickname, and email address.

<admin name="Example User"
    nick="example-user"
    email="example-user@example-email.com">

Then locate the bind tag and here we have the address values where the server will be available. If you leave it blank, it will be accessible from any host which is desired if you want it to be available via the internet. The other ports value is to define the listening port which by default is 6667 and in type leave it clients.

<bind address="" port="6667" type="clients">

The admin user can shut down or restart the server. But to do this he has to enter a password which we can define in the power tag in the diepass and restartpass values.

<power diepass="shutdown-password" restartpass="restart-password" pause="2">

After this, he creates an operator user in the oper tag. Again, in the host value he can define from which location he can log in. In my case, I have left it accessible from any host, but a good practice would be to limit it to localhost or a specific IP. Also, set a password and leave the type in NetAdmin.

<oper name="example-user"
    password="password"
    host="*@*"
    type="NetAdmin">

We won’t touch anything else, for now, so save your changes and close the editor.

Now, you should edit these two files. The first one is /etc/inspircd/inspircd.motd which will serve as the first message. And the other one is /etc/inspircd/inspircd.rules where you can set rules for behaviours that can be displayed from a client.

To apply the changes, you have to restart the program.

sudo systemctl restart inspircd

And you can check the status of it

sudo systemctl status inspircd

Testing the installation

The best way to find out if everything went well is to run a client. In this case, we have chosen weechat as it is terminal and lightweight. Ideal for testing.

So, install it on Ubuntu and Debian running

sudo apt install weechat

Run it

weechat

Now add our server by running

/server add [server-alias] [your-domain]

When added, you can connect via

/connect [server-alias]

If you need to, you can connect as an operator user.

/oper [server-alias][password]

As you can see in the screenshots, everything went fine.

Recommended: Securing the server with SSL certification

To secure your communications you should obtain and add SSL certificates using Certbot.

So, install it.

sudo apt install certbot

and get a certificate for your domain

sudo certbot certonly --standalone --preferred-challenges http -d [your-domain]

And now to add it to the program and secure the connection, create a folder for it inside the program settings

sudo mkdir /etc/inspircd/ssl

Then, copy the obtained certificates to this folder

sudo cp /etc/letsencrypt/live/[your-domain]/fullchain.pem /etc/inspircd/ssl/cert.pem
sudo cp /etc/letsencrypt/live/[your-domain]/privkey.pem /etc/inspircd/ssl/key.pem

Now make the irc user the owner of that folder to prevent others from taking advantage of it.

sudo chown -R irc:irc /etc/inspircd

Now in the Inspircd configuration file, you need to add the following information

sudo nano /etc/inspircd/inspircd.conf

And under the bind tag add the following.

<gnutls
    certfile="/etc/inspircd/ssl/cert.pem"
    keyfile="/etc/inspircd/ssl/key.pem"
    priority="SECURE192:-VERS-SSL3.0">
<module name="m_ssl_gnutls.so">

In short, we are just indicating the location of the certificates.

Save the changes and restart the service

sudo systemctl restart inspircd

And now to connect, remove the previous alias in weechat.

/server from the [alias]

When using SSL the port to use is 6697 which you have to open in the firewall and add another alias as follows.

/server add [alias] [your-domain]/6697 -ssl

And then connect again.

So, enjoy it.

Conclusion

In this post, you learned how to install an IRC server using Inspircd. This way you can create one and manage it without any problems.

According to the project website:

Vim is a highly configurable text editor built to make creating and changing any kind of text very efficient. It is included as “vi” with most UNIX systems and with Apple OS X.

Vim is rock stable and is continuously being developed to become even better. Among its features are:

• Persistent, multi-level undo tree.
• Extensive plugin system.
• Support for hundreds of programming languages and file formats
• Powerful search and replace
• Integrates with many tools

So we can say that Vim is an improved version of the mythical text editor Vi. This makes it very popular among sysadmin and even developers.

Install the Latest version of Vim

The best way to get the latest version of Vim is to compile it from the source code. It is lightweight, does not have many dependencies, and is more secure. So this is the way we will do it.

So, open a terminal or start an SSH session and run it:

sudo apt update
sudo apt upgrade

With the system upgrade, we can then install the build-essential package which contains the package compilation tools.

sudo apt install build-essential

Then create a folder where the compiler package will be. I have chosen this path:

mkdir -p /home/angelo/vim

But you can change it to whatever you want.

Then, download the packages needed to perform the compilation:

sudo apt install ncurses-dev unzip
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Note, selecting 'libncurses-dev' instead of 'ncurses-dev'

Suggested packages:
  glibc-doc manpages-dev ncurses-doc zip
Recommended packages:
  manpages-dev
The following NEW packages will be installed:
  libc-dev-bin libc6-dev libncurses-dev linux-libc-dev unzip
0 upgraded, 5 newly installed, 0 to remove and 36 not upgraded.
Need to get 4,902 kB of archives.
After this operation, 28.0 MB of additional disk space will be used.
Do you want to continue? [Y/n]

After that, download the Vim source code using the wget command.

Now decompress it using the command unzip

unzip master.zip

Access the src folder inside the generated folder

cd vim-master/src

And start the compilation configuration taking as the path the folder we have created.

./configure --prefix=/home/angelo/vim

My recommendation, always when compiling a package from source code, I do it in a location that does not require root privileges and that I can manage. This way if we want to uninstall it, we would only delete the folder where the compilation was configured.

Create the package:

make

And finally, do the installation:

make install

To test the results, you can access the bin folder that has been created in the package creation path.

cd /home/angelo/vim/bin

There you will find the freshly compiled binary that you can start using. For example, I will show the compiled version.

./vim --version

And that is it. Enjoy the latest version of Vim.

Conclusion

Having the latest stable version of a program gives us access to improvements and new features as well as bug fixes. Today I have shown you how to get the latest version of Vim quickly and easily.

According to the project website:

SpiderFoot is an open source intelligence (OSINT) automation tool. It integrates with just about every data source available and utilises a range of methods for data analysis, making that data easy to navigate.

SpiderFoot has an embedded web-server for providing a clean and intuitive web-based interface but can also be used completely via the command line. It’s written in Python 3 and GPL-licensed.

So it is an interesting tool if we have servers with various services on the network.

Install Spiderfoot on Debian 10

The installation process is quite simple and we will do it from a terminal environment.

First, update the system completely

sudo apt update
sudo apt upgrade

After that, you have to install some packages needed to run SpiderFoot

sudo apt install python3 python3-pip python3-setuptools
Reading package lists... Done
Building dependency tree

After this operation, 3,772 kB of additional disk space will be used.
Do you want to continue? [Y/n]

Then, you need to upgrade PIP so that it can work properly

pip3 install --upgrade pip

Now we can download the SpiderFoot package with the help of the wget command.

Note: At the time of writing this post, the latest stable version is 3.3.

Decompress the archive with the tar command

tar -xvzf v3.3.tar.gz

Access the folder that has been generated:

cd spiderfoot-3.3

And with PIP, install with the following command:

pip3 install -r requirements.txt

After the process is completed, you can start the web interface with the following command:

python3 sf.py -l localhost:5001

To end the execution you can press CTRL + C keys.

Now, if SpiderFoot has been installed on a server, you can alter the command so that it can be accessed by any host

python3 sf.py -l 0.0.0.0.0:5001
2021-04-01 00:06:35,119 [INFO] Starting web server at 0.0.0.0:5001 ...

Now all you have to do is open a web browser and visit http://your-server:5001 and you will see the main screen.

So, you can use it

Conclusion

SpiderFoot is a professional application that allows us to scan our server. For how advanced it is, its use is quite simple and the installation is within the reach of anyone.

Jitsi Meet is a pretty valid alternative to Google Hangouts, but in this case, we’re talking about a completely open-source alternative. On the other hand, it’s free and even though it’s not, it offers some advantages that we could consider premium like HD Audio support. Everything 100% encrypted.

In these times in which the formal work has been threatened, some companies have found in Jitsi a quality tool. Especially because it does not require the creation of an account and because it can be installed on your server.

Some features of Jitsi Meet are as follows:

• Share your desktop, presentations, and more.
• Invite users to a conference via a simple, custom URL.
• Edit documents together using Etherpad.P
• Pick fun meeting URLs for every meeting.
• Trade messages and emojis while you video conference, with integrated chat.

Again, all this for free, open-source, and encrypted conversations. So, technologically it’s pretty competent.

Install Jitsi on Debian 10

We will be able to install Jitsi with the repository that the developers give us. This ensures that the integration with the system and the package manager is complete.

To perform the installation, we will have to connect to our server and update it.

sudo apt update
sudo apt upgrade

Then, it is necessary to change the hostname of the computer for your domain.

sudo hostnamectl set-hostname [domain]

Replace [domain] with yours.

Then modify the hosts file of the server and add the following line:

sudo nano /etc/hosts 
127.0.0.1 domain  

Before continuing, you have to make sure that ports 80, 443 and 4443 of the TCP protocol and port 10000 of the UDP protocol are open in the firewall.

Now it is time to install the gnupg package which contains instructions for adding GPG keys from external repositories.

sudo apt update
sudo apt install gnupg

Now you can download and add the GPG key from the Jitsi repository.

wget https://download.jitsi.org/jitsi-key.gpg.key
sudo apt-key add jitsi-key.gpg.key

Next, create a new file that will contain the information for us to add the Jitsi repository.

sudo nano /etc/apt/sources.list.d/jitsi-stable.list

And add:

deb https://download.jitsi.org stable/

Save the changes and close the editor.

So, refresh APT so that the repository information can be loaded.

sudo apt update

And finally, install Jitsi by running:

sudo apt install jitsi-meet

During the installation, we will be asked to enter the hostname of our server, which can be your domain.

Then you will be asked if you want to generate a new certificate or use an existing one. In this case, I will generate new certificates.

Preparing Jitsi for the first use

By default, Jitsi is very secure but we need access from the web to be secure too and that is why we need to generate TLS certificates. To do this, install the Certbot package.

sudo apt install certbot

Then run a script that provides us with the Jitsi installation where we only need to enter our email address.

sudo /usr/share/jitsi-meet/scripts/install-letsencrypt-cert.sh

In the end, you will see a success message.

Now the next step is to prevent anonymous users from creating rooms. To do this edit the configuration file for your domain.

sudo nano /etc/prosody/conf.avail/your_domain.cfg.lua

Remember to replace your_domain with yours .

And look for the value

 authentication = "anonymous"

And replace it with:

authentication = "internal_plain"

At the end of the same file add the following section:

VirtualHost "guest.your_domain"
    authentication = "anonymous"
    c2s_require_encryption = false

Don’t forget to replace the your_domain value with yours. With this configuration, we will make it so that anonymous users can log in to rooms created by authenticated users.

Save the changes and close the editor.

Now we also need to edit another file to add the host of the guest users.

sudo nano /etc/jitsi/meet/your_domain-config.js

And change the line

// anonymousdomain: 'guest.example.com',

To

anonymousdomain: 'guest.your_domain',

Again, save the changes and close the editor.

Finally, edit the /etc/jitsi/jicofo/sip-communicator.properties file.

sudo nano /etc/jitsi/jicofo/sip-communicator.properties

And add the following line:

org.jitsi.jicofo.auth.URL=XMPP:your_domain

Replacing your_domain with yours.

Save the changes and close the editor.

Now create a new user who will be able to create new rooms:

sudo prosodyctl register [user] [your_domain] [password]

Replace the fields with the values you prefer.

To apply all changes, restart the services.

sudo systemctl restart prosody.service
sudo systemctl restart jicofo.service
sudo systemctl restart jitsi-videobridge2.service
sudo systemctl restart nginx

And you can visit https://your-domain and enjoy Jitsi.

Conclusion
