What is PuTTY and what is it for?

I have already more than one article in which I talk about PuTTY but I never wrote about this great application to show you in broad strokes what PuTTY is and what it is for .

I will do the analysis of PuTTY from a Windows user point of view, although PuTTY for Linux also exists , only that among users of this operating system it is more common to use the ssh command.

I will try to explain what can be done with PuTTY without going into many technicalities and in a simple way so that everyone can understand it.

What is PuTTY and what is it for?

PuTTY is an SSH and Telnet client with which we can connect to remote servers by logging into them that allows us to execute commands. The clearest example is when we use PuTTY to execute commands on a VPS server and thus be able to install some program or configure some part of the server.

The Telnet client part is more unknown to me, but the clearest example of use is to connect to our home router to configure it through Telnet and open ports, etc.

In short, with PuTTY we managed to open a command line session on the remote server to manage it.

Download PuTTY

PuTTY can be downloaded directly from its official website , which does not look great but allows us to download PuTTY for free and even other complementary applications.

PuTTY Advantages

One question that may arise is why use PuTTY? What are its advantages? This application is like everyone else, it has its good parts and bad parts, but it is true that it mostly has great advantages such as the following:

  • It is free and open source.
  • Available for various platforms (Windows and Linux).
  • It is a portable application.
  • Simple and manageable interface.
  • Very complete and offers great flexibility with many options.
  • It is constantly developing.

Basic use of PuTTY

I will not extend much in this section and I will give a simple indication to connect to a VPS server, so you can follow the tutorials on Vozidea servers .

After executing PuTTY, the Session section is shown with the basic options and you just have to:

  • Enter the IP or Hostanme of the remote server.
  • Select the port (normally to connect through SSH is 22 by default).
  • Select the SSH option in connection type (it is usually marked by default).
  • We click on the Open button.
  • We may be shown a warning, which we accept and after a few seconds will request our username and password to log in to the remote server.

With these simple steps we will be connected to our remote server. Personally I see PuTTY as a very powerful tool, with which we can do things like creating a SOCKS proxy with an SSH tunnel among many others.
