【 Enter the Router by Telnet 】 Guide + Configuration ▷ 2022

For those networks that are geographically distant, we can access the different computers remotelybenefiting us mainly by saving transfer time, as well as 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 we will 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 virtually partitioned server.

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

The most prominent 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?

This computer tool is very useful for network administrators due to the following benefits:

Remote access to the router

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

Network management

In addition to the configuration that we can do far away on 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 instance.

Security control

By being able to open and close ports remotely, it is not necessary to present ourselves 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 it virtually and we will be able to make all the necessary changes.

Savings in transfer costs

When we are busy with other tasks, we can delegate our function 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 personal transportation costs.

Quick problem resolution

By being able to access remotely, we have the possibility of solving problems in a more practical and faster way at the same timesince 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 configuration features without getting inconvenient at the workplace where the network is physically located.
