Secure Shell Comunication
A great advantage in Linux (and less in other OS) is its multiuser platform. That allows
to several people to connect and do processes into a computer at the same time. So here
we are going to take advantage of that fact and we will use LabFama

ORCA, and
Gnuplot is already installed.
For windows users the console emulator
Cmdr will use the work to connect our hardware with
the server, Cmdr has already installed some utilities that are useful.
