Enter the Router by Telnet  Guide + Configuration ▷ 2020

For those networks that are geographically distant, we can access the different computers remotely, benefiting mainly in saving travel time, as well as in increasing control of the configurations for the different nodes.

PuTTY is a tool with which we can remotely access a network and work in the client-server relationship without any problems. In this way we will be able to configure our router through Telnet as if we were sitting in front of the computer.

In this article we will talk about what this PuTTY computer tool is about, as well as show you the advantages of using it and the steps we need to take to configure our router via Telnet.

What is PuTTY and how does it work on our router?

When we need to communicate remotely with a server, taking into account the client-server architecture protocol, we can use PuTTY (from English, Port unique terminal type). Which is a system that allows us to execute commands that will allow us to work on the virtual partitioned server.

In this way we can remotely access our router thanks to the network protocol “Telnet”, which will perfectly emulate access to it through a command line. Allowing to configure it, open ports and segment the data packets through the Quality of Service, among other actions.

The most outstanding features of this method is that it supports IP version 6 as well as public-level key authentication.

What are the benefits of doing a PuTTY setup on my router?

What are the benefits of configuring with PuTTY on my router

This computing tool is very useful for network administrators for the following benefits:

Remote access to the router

When we need to access the network that is far from us, we can use this technology that will allow us to have absolute control of the device as if we were next to it.

Network management

In addition to the configuration that we can do remotely in our router, We can also manage the different components that belong to the network in such a way that we can open or close benefits for Internet access, for example.

Security control

By being able to open and close ports remotely, it is not necessary to be present as network administrators to be able to establish all the security protocols that a network architecture far from our geographical area will have.

We simply have to access virtually and we can make all the necessary changes.

Savings in transfer costs

When we are busy with other tasks, we can delegate our role to different programmers who can help us in the same way that we would without the need to be on site, thus saving time and also personal transport costs.

Fast problem resolution

By being able to access remotely, we have the possibility to solve problems in a more practical and faster way at the same time, since we will not need to be present in the place to be able to access the network.

Didactic support

When we work with a group of network administrators and we want to show the different members how the router and other elements of the network are configured, we can use PuTTY to highlight the configuration features without causing inconvenience at the workplace where the network is physically located.

Steps to connect to the router by Telnet to do an advanced configuration with PuTTY

To configure our router through Telnet using PuTTY and we will do these steps:

We configure the Windows features

In order to start the configuration process we will do this guide that will allow us to adjust our OS:

  • We headed “Start” located at the bottom of our screen in the Windows operating system.
  • We choose the option “Control Panel”.
  • We seek “Programs” and we click on this section.
  • In the right part of the configuration panel we will have to choose the section “Programs and characteristics”, which will have 5 tools that we can use.
  • Once we have carried out these steps, it will appear on the left side of the screen “Enable or disable Windows features”.
  • We choose “To accept”.

We create the Telnet server

At this time we will define a computer as a server, for this we will follow this process:

  • We choose “Telnet Server”To guide us a little better, all the alternatives are arranged alphabetically, so this option is one of the last
  • We click on “To accept”.
  • We enter again “Control Panel” and we choose “Security system”.

  • We activate the option “Handbook”.
  • We click on “Apply”.
  • And later in “To accept”.

We start the Telnet service

Once we have defined the server, we will perform the configuration by Telnet:

  • In the upper left part of this window it will appear “Start the service”, where we will click.
  • At this time we will see that 3 options are enabled and it is stop the service, adjust it, or restart Telnet
  • We return to the control panel by selecting the option “Systems and security” to enter “Management tools”.
  • We choose “Team management”, which is the first option we have on the list.
  • On the left it will appear “Local Users and Computers”, where we select the same.

We add the client team

We need to do these steps to configure the client computer:

  • We will have to choose next “Groups”.
  • We look for the alternative “Telnet clients”, which is located last on the list.
  • We right click and choose “Properties”.
  • In the tab “General” we press on “Add”.
  • In “Locations” A name that we have previously chosen will appear so that we can enter that team as a client. We will have to write exactly the same in the writing box that appears at the bottom of the dialog box, where it says “Enter the object names you want to select”.
  • We select “To accept”.
  • We click on “Apply” and again in “To accept”.

Activate the Telnet communication option

When we have already made the configuration in our computer, we will now go through the connection by Telnet to activate our equipment as clients.

We follow this guide:

  • We select “Control Panel”.
  • We seek “Uninstall a program”.
  • On the left side we choose “Enable or disable Windows features”.
  • We select the box “Telnet Client”.
  • We press on “To accept”.

  • We wrote .
  • Then, .
  • We write the name of the team to which we are going to connect.
  • We write the login and the access password.

In this way we have already entered the equipment from where we can configure the router via Telnet.
