$ping 10.10.10.20
If the ping works successfully means that our connection is ready. If not, you can check section
6 again or read our blog about changing the local IP.
For accessing to the Raspberry PLC we will run the command ssh shown below:
$ssh pi@10.10.10.20
The connection will start, but first the password provided before will be required. If the
username and password are correct, you can start the SSH session.
When an SSH connection is made for the first time, the server delivers the server's public key
to the SSH client. The system will alert you to this and offer you the option of accepting the key
or rejecting it. You have to accept the key, as it will be stored in the register and will be used to
contrast it with the one sent by the server on each connection. If for some reason the key
changes, a new notice is generated in which the authenticity of the received key will be raised,
since someone could be posing as the server to which we want to connect.
Once connected, will be a full access to the Raspberry PLC and the user will be able to control
it and set the functions needed. Also new users or the password could be changed as the
device IP. The commands for going through the Raspberry are the same as the Linux terminal.
The most useful are the following:
•
cd: to navigate through the Linux files and directories.
•
ls: is used to view the contents of a directory.
