What Does That Meangreedy And Unscrupulous

This is an interface that serves the devices to communicate with a program THROUGH of the network, port general mind, we see them listed.

How does this work?
As mentioned, the ports are listed these, use a protocol, which serves to tell the destination of the package or which will receive.
This can be done in simultaneous occasions, an example was as entry, which wanted to hear that we had open ports.
ports are indicated by a 16-bit word, so it will exist 65535 ports available, we may use any of these for something specific, for example if we want to transmit important data on the server, but we want to tell on which port , not be easy for the intruder or the person who is listening to where the information comes out.

Here I give you a list of the most common ports

But if we want to see the ports, we have enough, to open the end and enter the following:

sudo gedit / etc / services that is where are located ports. You
open a window like the previous one and you will port name, eg 22 / tcp that I have to transfer ssh , among others. It is only
question that explore ports to know what each one. Summary


If you did not understand at all well, imagine this, you want to send a package to Germany, and you're in some else in the world, what you do is go to the messaging or one that gives you the service, what they do is they fall into places, such as Germany package can not go to Korea because they do not go to the same destination, and to be specific instead sent to, and upon arrival, it is classified also of where it came from, this would be a simple example of how it works.
