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.

The lounge is a web-based IRC client. It has many modern features such as push notifications. Besides being open source, it is also cross-platform because it can be installed on various operating systems such as Windows, Linux or Mac OS. On the other hand, the application has a new responsive graphical interface, which makes it ideal for daily use, all this without sacrificing performance.

So, let us start.

1.- Upgrade the system

This is an essential step if you want to keep your operating system stable and robust. Therefore, it is always advisable to do it frequently.

Open a terminal and run the following command:

:~$ sudo apt update && sudo apt upgrade

Upgrading the system is important because you will install all the necessary security patches to improve system security. Above all in a production machine.

2.- Install Node.js

The next step to install this modern IRC client is to have node.js installed. The Lounge is built with web technologies, and part of those technologies includes node.js.

The application requires at least version 6.

So, in this post, you will learn to install node.js on Ubuntu 20.04.

3.- Install YARN

YARN is dependency management that focuses on speed, reliability, and security. Using YARN we will be able to install the latest stable version of The Lounge in an easy way.

So, run these commands:

:~$ curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -
OK
:~$ echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list

Next, install it.

:~$ sudo apt update && sudo apt install yarn

So, Node.js and YARN are correctly installed.

4.- Getting The Lounge on Ubuntu 20.04

Now it’s your turn to install The Lounge, so use YARN.

:~$ sudo yarn global add thelounge

Once you have finished the installation process run The Lounge with this command:

:~$ thelounge start

Then, you will see this.

After that, open your web browser and go to http://localhost:9000/ or http://SERVER_IP:9000.

5.- Create a new user for the Lounge

Now in order to enjoy The Lounge, it is necessary to create a new user. Stop, go to the terminal, and press CTRL + C to end the execution of The Lounge. And type the following.

:~$ thelounge add angelo

This command will create the angelo user and then you will be prompted to create the password and an option about the logs.

Start The Lounge again:

:~$ thelounge start

And come back to the web browser, and log in. You will see this:

On the previous screen, you will see the IRC options. You will be able to configure the nickname, the server, and the channel to use. Once you have done it, you can click on the connect button.

So, that is it.

In case you did not know, Ejabberd is a messaging server that uses the XMPP protocol. It is open source and has a community version that will save us money, ideal if our company is small. Its main objective is to be fast and scalable, so, that it can be used in almost any scenario.

So, let us start to install Ejabberd on CentOS 7.

1. Upgrade the system and install glibc

First, you need to update the system. You know, with this you will have installed the latest security patches and you will be able to enjoy a more stable and secure system.

:~$ su
:~# yum update

Now, you have to install a required library. It is glibc.

:~# yum install glibc

So, now you have the system updated and with glibc installed, you can continue with the installation.

2. Download and install Ejabberd

The next step is to download the Ejabberd binaries from the website. In this case, I will use the binary in. RPM format. At the time of writing this post, the latest stable version of Ejabberd is 18.12.1.

:~# yum install wget
:~# wget https://www.process-one.net/downloads/downloads-action.php?file=/ejabberd/18.12.1/ejabberd-18.12.1-0.x86_64.rpm

After that, install the downloaded package using yum.

:~# mv downloads-action.php\?file\=%2Fejabberd%2F18.12.1%2Fejabberd-18.12.1-0.x86_64.rpm ejabberd.rpm
:~# rpm -ivh ejabberd.rpm

Note the following, the ejabberd initialization script is located at /etc/init.d/. In addition, the ejabberd user will be created.

3. Starting the Ejabberd service

Now it is necessary to work with the Ejabberd service, to start it or restart it when it is convenient.

All you have to do is copy the ejabberd.service file located in the /opt/ejabberd-18.12.1/bin/ folder to the /etc/systemd/system/ folder.

:~# cp /opt/ejabberd-18.12.1/bin/ejabberd.service /etc/systemd/system/

In order for the service to be recognized by systemd, it is necessary to refresh the services.

:~# systemctl daemon-reload

After that, enable and start the service. Finally, it is a good idea to check the status of the service.

:~# systemctl enable ejabberd
:~# systemctl start ejabberd
:~# systemctl status ejabberd

As you can see in the image above, everything is going well. It is now necessary to create an administrator account.

4. Create an administrator account and access from the web browser

To access the Ejabberd administration panel, it is necessary to create an administrator account. Let us go for it.

First, access the folder where the binary is.

:~# cd /opt/ejabberd-18.12.1/bin/

Then, use the following formula to create your user.

:~# ./ejabberdctl register user localhost your_password

Of course, replace user and your_password by yours. And localhost by your hostname.

After that, you have to edit one file to give administration rights to the new user.

:~# nano /opt/ejabberd/conf/ejabberd.yml

Then, restart the service to apply the changes.

:~# systemctl restart ejabberd

After that, set the right rules in the firewall for ejabberd. Remember, ejabberd uses the 5280 port.

:~# firewall-cmd --add-port=5280/tcp --permanent
:~# firewall-cmd --reload

Finally, open your web browser and go to http://SERVER_IP:5280/admin and log in. Remember the user is complete including the hostname. In my case is angelo@osradar.

So, that is it.

Conclusion

Ejabberd is a great alternative to deploy an XMPP server quickly and easily. That’s why Ejabberd is listed as one of the leading solutions in this segment. Its installation in CentOS 7 is quite simple and does not present too many drawbacks.

Slack is an application to develop communications within an organization. Or even, for teams within one. In addition, it has several features for offering a powerful center for information exchange between many people related to the project.

Slacks

Some Features

To organize team communications efficiently, Slack implements channels that label a conversion with a #.

In addition, it is possible to access a history of conversations to search through common words. Excellent, not to lose sight of valuable information about our project.

Slack Brings important information and alerts into relevant channels by connecting services like Zendesk, Salesforce, JIRA, and more.

All these and other characteristics have one thing in common, security. Slack uses strong encryption protocols so that your communications are not intercepted, including SOC 2 Type II, ISO 27001, and HIPAA.

Team communication importance

In this new era, projects require even more than their members have clear project requirements. In addition, we are in a hurry to offer innovation, so that not much time can be wasted on communications.

So, the organization is the key to team communication so that all information and interaction can be developed effectively and smoothly.

A great team communication ensures that the project is successful, something vital in a company.

How to install Slack on Linux

Slack is a great investment for your organization and projects. As I said before, you should not underestimate the value of communications within a team. So, install it on Linux.

The easiest way to do it in Ubuntu is through snap. This packaging system developed by Canonical means you don’t have to worry about libraries. However, you can also install it using the .deb package in Debian and derivatives such as LMDE.

If you use Fedora, CentOS or OpenSUSE, don’t worry that there is also a .RPM package so you can do it in your favorite distribution without complications.

First, open a Terminal and run:

For Ubuntu 17.10, 18.04. 18.10:

:~$ sudo snapd install slack --classic

If you want to download it on Debian 9:

:~$ wget https://downloads.slack-edge.com/linux_releases/slack-desktop-3.3.3-amd64.deb -O slack.deb

Next, install it.

:~$ sudo dpkg -i slack.deb

For CentOS 7, OpenSUSE 15 and Fedora 29

:~$ wget https://downloads.slack-edge.com/linux_releases/slack-desktop-3.3.3-amd64.deb -O slack.rpm

Then, install it.

:~$ sudo rpm -ivh slack.rpm

Note: At the time of writing this post, the latest stable version of Slack is 3.3.3. It is likely that in the future you will have to modify that value in order for the command to work.

And that’s it.

Preparing Slack for the first use

The first thing you have to do is open Slack. You’ll see something like this.

There you must log in with your created workspace. If you don’t have one, you can create it adding an email.

Then, type the received code. And put your company name.

Next, you’ll need to write down what your team is working on.

Then, you can add other members to the project.

After that, you’ll have Slack set up.

Then, you will see the Slack main screen.

And that’s it.

Conclusion

Team communication is important to ensure the success of a project in any field. That’s why applications arise to improve the way they are carried out in a given project.
