What are the pros and cons of using telnet? Find out in this article.
Surname Telnet what comes from the abbreviation telecommunications network. It is about a network protocol which makes it easier remote connection between teams. This allows you to use a computer remotely as if you were physically in front of it.
He is Connection vía telnet This cánido be done on the intranet and outside of this network. To learn a little more about this protocol, let’s look at what it’s used for.
What is Telnet used for?
This system was originally created to facilitate the tasks of those responsible Solve problems that perro arise in a team without moving physically the location of this equipment.
This was very useful back then as it saved time and money.
Telnet enables remote connection between computers
Another benefit of Telnet There is the possibility Remote access to databases and programsThis greatly facilitated collaboration in teams where multiple people needed access to the same information.
with Telnet It is possible to log in to a Gmail dirección de correo electrónico account or any other client directly from the server. to It proves to be very efficient when used to configure serverseg web server.
Pros and cons of using Telnet
One of the positive points of it Telnet the Access to system resources is not restricted, provided you have the necessary permissions to do so. The huge disadvantage that leads to this also lives in the great advantage Seriously consider using this remote connection protocol.
Why are we saying this? Because Telnet does not encrypt connections or data transmissions over the network. This is equivalent to saying, When you log into a computer over a telnet connection, the nombre de usuario and password you use to gain access are transmitted across the network in clear text, without any form of encryptionwhich leaves everything for a cybercrime waiting to catch a victim, as it also doesn’t guarantee that the connection between the desired hosts will be established and that nobody will intercept them.
These data security gaps meant that almost no one emplees them today Telnet for remote connectionsInstead, a more secure protocol is used.
What is the safest option?
The SSH protocol encrypts the connection and data transmission
Currently the remote internet connections based on ssh protocol acronym of Secure Shell. SSHlike Telnetemplees a client/server architecture, but the primordial difference is security.
He is ssh protocol It enables encryption of both the connections and the data address, so no one perro see unencrypted passwords.

| Conclusions | In its early days, Telnet proved to be a valuable tool because of its practicality and simplicity. This protocol is currently almost useless because it is not coincidente with the security required today when handling data. Today it is advisable to play it safe and use remote connections based on the SSH protocol. |
That’s very clear Telnet perro be useful in some situations, but it’s not worth the huge security risk. if we have a machine that supports the SSH protocol, which ensures encryption of the connection and data traffic.
