Security is an essential aspect in everything that the human being does, including within the technological area, so connecting remotely by SSH to a server (in this case, Linux) has become a habit among those who work with the programming.
Within Linux it works as a tool that is integrated into default way. However, it can be installed as a third party program through commands.
Since this operating system works as a free code space, it is an ideal area to connect via SSH to a server. Given the increases the freedom of use and the security protocol of the same.
Secure shell it is quite a dynamic instrument as far as its use is concerned. In this article we will give a brief introduction about it and we will talk about how to achieve this connection through Ubuntu.
What is the function of connecting via SSH to a server?
Being SSH the acronym for Secure Shell, this protocol works as the security parameter that seeks the administration of the aspects related to the connection between networks.
By this we refer to equipment comor switches or routers, and the internal aspects of a computer, known as servers, which work to achieve transmission. These SSH servers can even be created through an Android smartphone.
Every time a developer executes this type of connection, they acquire the full domain or server management in question. Working with him through a series of commands that are known as commands.
These commands can be run automatically through the Linux “Terminal” window. So it is an ideal operating system to connect via SSH to a server.
Advantages of connecting via Secure Shell to a domain
It is well known that through servers a constant transmission of information is carried out from one computer to another. From SSH you can make safe copies of files that are transmitted through the selected address, if needed.
Likewise, and as we said before, this aspect gives the server a new layer of security. Helping to avoid the manipulation of information by third parties.

All this is through a principle of confidentiality, where each of the data transmitted through the site is encrypted and stored in the same way.
It should be noted that in the event that you modify any of these aspects by yourself, or a third party does, Secure Shell has a integrity evaluator. So you can detect when malicious situations arise.
Lastly, encryption can only be granted by the owner of the server. It goes through an authentication process previously established by itself, thus avoiding the invasion of privacy.
Instructions to connect by SSH to a server through Linux
Before entering, it is necessary to have all the information necessary to access a server. These are the server address, port number, username and password.
We must mention that, generally the server address refers to the domain name or IP address through which the data transmission is carried out.
Once you have this information, you just have to access the Linux “Terminal” window to enter the command “ssh [email protected] -p portnumber”.
Clearly, it is necessary to replace each data of the command based on the information of the server that you manage. So when pressing “Enter” only requests the key of the server in question.
From this point on, the series of commands entered depends on the types of configurations and evaluations to be carried out. Thus being able to inspect the directories or manipulate work on the same server.
As you have seen so far, connect remotely by SSH to a server through Linux is very easy. Well, the operating system itself has the tools to achieve it. The process is quite practical, as it can be said to try to see the failed connection attempts of a server in Linux by SSH.

For this and other reasons, the company that authored Ubuntu it is still an excellent option for developers. Since its free code allows them to work harmoniously with the necessary aspects and offer an optimal result in your project.
