Since this operating system works as a free code space, it is an ideal area to connect via SSH to a server. Since increases the freedom of use and the security protocol of the same.

Secure Shell it's a pretty dynamic tool when it comes to using it. In this article we will give a brief introduction about it and talk about how to make this connection through Ubuntu.

What is the purpose of connecting via SSH to a server?

Being SSH the acronym for Secure Shell, this protocol works as the security parameter that tries to manage the aspects related to connection between networks.

By this we refer to equipment such as switch o router and the internal aspects of a computer, known as servers, which work to achieve transmission. These SSH servers can also be created via an Android smartphone.

Whenever a developer makes this type of connection, they acquire the total domain or server management in question. Working with him through a series of commands known as commands.

These commands can be run automatically through the Linux "Terminal" window. So it's an ideal operating system to connect via SSH to a server.

Advantages of connecting to a domain via Secure Shell

It is known that a constant transmission of information from one computer to another takes place through servers. From SSH it is possible make secure copies of files which are transmitted via the selected address if necessary.

Also, as we said earlier, this aspect gives the server a new level of security. Help avoid the manipulation of information by third parties.

All this 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 case you change any of these aspects yourself, or if a third party does, Secure Shell has a integrity assessor. This way you can detect when malicious situations occur.

Finally, encryption can only be granted by the server owner. It goes through an authentication process previously established by itself, thus avoiding the invasion of privacy.

Instructions for connecting via SSH to a server via Linux

Before entering you must have all the information necessary to access a server. These are the server address, port number, username and password.

We must remember that generally the server address refers to the domain name or IP address through which data transmission is carried out.

Once you have this information, you just need to access the Linux "Terminal" window to enter the command " ssh username @ hostname -p portnumber ".

Clearly you need to replace any command data based on the information from the server you manage. So when you press "Enter" you are only prompted 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 made. Thus being able to inspect the directories or manipulate the work of the same server.

As you have seen so far, connect remotely via SSH to a server via Linux is very simple. Well, the operating system itself has the tools to achieve it. The process is quite practical, as can be said for trying to see failed connection attempts of a server in Linux from SSH.

For this and other reasons, the company of authors of Ubuntu remains an excellent choice for developers. Since its free code allows them to work in harmony with the necessary aspects and deliver an optimal result in your project.
