Security is an indispensable aspect in everything that human beings do, including within the technological area, so connecting remotely via 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 by default . 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. Since it increases the freedom of use and the security protocol of the same .
Secure Shell is quite a dynamic instrument in terms of its use. 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?
As SSH stands for Secure Shell, this protocol works as the security parameter that seeks to administer the aspects related to the connection between networks .
By this we refer to equipment such as 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, he acquires the total domain or management of the server 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 by SSH to a server.
Advantages of connecting via Secure Shell to a domain
It is well known that a constant transmission of information is carried out through the servers from one computer to another. From SSH you can make safe copies of the files that are transmitted through the selected address, if you need them.
Also, 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 yourself, or a third party does, Secure Shell has an 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 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 address of the server, the port number, the username and the password to access it.
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 username @ hostname -p portnumber “.
Clearly, it is necessary to replace each data of the command based on the information of the server you manage. So that when you press “Enter” it only asks for 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 the work of the same server .
As you have seen so far, connecting remotely via 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 many other reasons, the Ubuntu author company remains an excellent choice for developers. Since its free code allows them to work harmoniously with the necessary aspects and offer an optimal result in your project.
