What is SSH

SSH, or Secure Shell, is a protocol used to connect two computers together wirelessly. With this in mind, set up remote access through a secure channel. In this channel, information travels encrypted between computers. In addition to the protocol, SSH is also the name of the program that implements it.

Therefore, it is a kind of remote access to be able to exchange files between computers. In other words, it is a technology similar to other protocols such as FTP and Telnet. However, as we have already pointed out, it is more focused on system administrators. At user level, you have other simpler alternatives such as remote desktops or clouds for file sharing.

In addition to connecting computers and exchanging files, it also allows you to securely copy data from a computer to an external client that has connected using RSA keys. These are more secure than login passwords. You can also simulate encrypted FTP sessions in order to exchange them.

In its favor is the fact that it is a very versatile protocol. In fact, it allows you to connect to the computer you configure as a server both from an internal network and remotely. Indeed, you are not dependent on them sharing the same network or being close to each other. However, to have this freedom in the connection between computers, you first need to configure one as an SSH server. After that, you will be able to connect to it from other devices.

Disadvantages

On the downside is that, being designed for professional environments. It is certainly a bit complex to use. A user without a lot of computer knowledge might be intimidated by it. Because in the end, the quickest and easiest thing to do if you don’t have much of an idea is to simply set up a remote desktop. Another simple option is to share files in the cloud to access them from any computer.

Nowadays, you will be able to use SSH from virtually any computer, regardless of its operating system. This is because it is a function that is implemented mainly through multiple third-party applications. Some of them are complex and require the use of the command line. However, we will try to make it as easy as possible for you.

How to configure SSH in Windows 11

To configure SSH in Windows 11, you have to activate a computer as a server. With this in mind, turn on the PC where you are going to have the data you want to access from other computers. Next, open the Start menu and type services.msc. Finally, click on the Services application will appear to open it. Next we will see how to configure SSH in Windows 11.

This will take you to the Windows services window. In it, you have a list of services, and in it, you have to right-click on the OpenSSH SSH Server service. In the pop-up menu, you can do two things: click on Start to simply launch the SSH server, or click on Properties to be able to configure it.

Now, launch the Windows Terminal application. In this console, as if logging in as administrator, type the command:

New-NetFirewallRule -Name sshd -DisplayName 'OpenSSH Server (sshd)' -Service sshd -Enabled True -Direction Inbound -Protocol TCP -Action Allow -Profile Domain.

When you do this, you will have enabled everything necessary and opened port 22 to be able to access this computer with an SSH client from outside your home network. The last step will be to find out and write down the IP of this computer. This is something simple that you can do from a simple website like ipinfo.io/ip.

Configuring the client machine

Now, go to the computer from which you want to connect to the one you have configured as a server. You will need to download a SHH client to it. We will use a program called PuTTY that you can get from here. Download its installer for your version of Windows and install it.

The installation process is simple and clean, without adware or anything complicated. You only have to choose the destination folder or if you want shortcuts, and it will not try to put any application you don’t want.

And once you have installed it, using PuTTy is easy. Just type the IP address where it says Host Name and click on the Open button, indicating first that it is an SSH. If you want, you can click on the Save button to save this address and session. On the other hand, if you are an advanced user, this tool will offer you dozens of options.

Some useful Putty commands

Below is a list of the main commands:

• Special Command: allows executing directly a series of common commands on the working machine. This option can appear, or not, depending on the machine connected.
• Event Log: It shows a record that details all the processes and data generated in the connection.
• New Session:Allows you to return to the main screen of the program to create a new connection to the same or another server with different parameters.
• Restart Session: Close the open session and restart it to start working with it from the login.
• Duplicate Session: It will create a duplicate of the current session.
• Saved Sessions: This is direct access to the sessions saved in the program, along with its preferences.
• Change Settings: Allows you to change some parameters of the current session settings.
• Copy All to Clipboard: Copies the entire contents of the program’s buffer to the Windows clipboard.
• Clear Scrollback: It is equivalent to use the CLS or clear function. That is, it cleans the screen but does not clear the buffer.
• Reset Terminal: Re-start the session completely, starting from scratch. Clears the screen and the buffer.
• Full Screen: Converts the console to full screen, and pressing Alt+Enter returns it to its normal state.

Very well, this way we have seen how to configure SSH in Windows 11. See you soon!

What is the purpose of KiTTY ?

This tool incorporates support for secure connections via HTTP or SOCKS proxy. And it adds default AES encryption for SSH connections. It also supports Blowfish and 3DES encryption algorithms. On the other hand, it uses Telnet. In short, this protocol allows remote access to any computer or server. This process uses terminal commands to remotely manage another computer. Seems a bit complicated? Well, tools such as KiTTY simplify the task.

In order to make this connection, two elements are necessary. First, a remote computer or server that supports Telnet with a user account. And then you need a local client. For example, KiTTY.

First steps to use KiTTY to connect to remote computers.

This is a free and open source program that can be downloaded from here. In addition to the installable, there is a portable version. In any case, it offers a very complete interface. Since it is full of options and customizable parameters. With the added advantage that everything is done from a single window. Well, this main window is divided into two sections. The left column shows the different categories and subcategories of the application. Consequently, just click on any of them and the parameters will be displayed in the right panel. In fact, the options range from the functionality to the appearance of the program.

Another interesting aspect is that KiTTY is ready to use. That is, with the default configuration, the app is ready to establish connections via Telnet. With this in mind, just click on Session. Then enter the credentials of the server to be connected. In fact, just specify the name of the server, the port to use, and the type of connection to set up. Finally, click on the Open button.

Types of remote connections supported by KiTTY

KiTTY supports many types of remote connections. Therefore, it is a versatile program. So it allows you to connect to many types of servers. Below we mention them:

Ultimately we have taken a look at PuTTY a simple SSH connection manager in Windows. The program is very intuitive. Of course your ability will grow as you use it. Bye!

The post Manages SSH connections from Windows 10 with PuTTY. appeared first on Linux Windows and android Tutorials.

PuTTY is a free application that allows you to make remote connections to any server or computer. Unlike other more advanced solutions, it does so using SSH and Telnet protocols. It is quite popular in Windows environments, and therefore sometimes forgets that there is version for Linux.

At this point, you may wonder what advantages the use of PuTTY brings over the use of the terminal and the SSH command. The truth is that with PuTTY we will have a lot of configurations to customize the connection. And all those configurations are available from a very simple and friendly graphical interface. So, this makes the job easier.

Recently version 0.73 has been released containing many patches that fix previous bugs. In fact, as indicated on the project website, these bugs brought security problems. So this version is very safe to use.

So, let us install it and use it.

Install and use PuTTY on Ubuntu 18.04 / Debian 10

One of the great advantages of PuTTY is that it is included in the official Ubuntu and Debian repositories. So the installation is a command away.

Then, open a terminal session and execute the following command:

:~$ sudo apt install putty

In case you are using Debian and do not have sudo enabled, I recommend you read this post:

How to enable sudo on Debian 10?

When the installation is finished, you can open the application with the following command:

:~$ putty

And you will see the following.

PuTTY comes with a pretty good default configuration. So to start with a connection at once, just enter the IP address or host you want to access. Then, we establish the port and the protocol. Also in this screen we will be able to save the configured session.

Clicking on Open will start the connection. If it is done for the first time, we will be shown a security warning.

Then Xterm will start and you will have to log in. In doing so, you will be able to use the connection.

As I told you at the beginning, PuTTY’s strength is its many options to configure. For example, it will look at the keyboard options we can configure.

Also, we can use a proxy to make the connection.

It is also possible to configure in depth the connection with the SSH protocol.

So, enjoy PuTTY.

Conclusion

PuTTY is one of those applications that can become necessary for daily work with SSH. It is light, fast, efficient and with many configuration options that will make it possible to connect to a server with all the ease and flexibility.

The installation is quite simple especially in Linux, so it is better to have it at hand.
