Free program to do Telnet and SSH, to connect to remote servers by command line. Available for Windows.
Introducing Putty, a program for making connections to remote servers via the command line. It is a simple but powerful program and possibly the most recommended option to connect via Telnet or SSH to other computers on the network. It is also free, which makes it doubly interesting.
Sometimes we have to connect with other machines to carry out their administration processes. In these cases we enter the computers by command line, without a graphical interface, to carry out actions such as maintenance or installation of applications, restarting services or working with the file system.
A typical case in which we may need to enter a machine by command line is that we have a dedicated server to host our pages. Although the dedicated server has a control panel to carry out typical actions such as registering domains, email addresses or FTP accesses, complete control of the server could not be done in any other way than by Telnet or SSH.
It could be said that Telnet is a network protocol, which is used to access a computer, connected to the network, from any point on the network, without having to be physically on that machine. SSH is a network protocol very similar to Telnet, in which we also connect to another machine through the network, although in this case the encrypted connections are made, which increases security, since other people could not see the communications between the source and destination computers.
The truth is that the introductions are of little use, since it is assumed that whoever wants to access Putty must already know the different network protocols and the specific needs they have to use Putty.
Putty can be obtained at the following address:
Once downloaded, we will verify that it is a single executable file, which can be double-clicked to launch it. We can copy the file to any directory on our computer and make the shortcuts that we want manually to have it at hand.
When executing it, we access a connection management window, from which we can configure access to remote servers and save them to enter later without having to enter the access data again.
To make it work we simply put the IP address of the server we want to access and the protocol we want to use, such as Telnet or SSH. If we want to save the access data for future times, where it says Saved Sessions we write a name for this session and press the Save button.
Once inside, we will access the command line to work with the machine with which we have connected. First, it will ask us for a username and password. Once the login is done, we can use the machine as if we were in front of it.
