Picroft to Picroft Communication

Skill-communicate

Communication with voice command between picroft or Desktop and another picroft with skill-gpio8s installed.

The communication is made using an ssh connection sending say_to_mycroft command to a remote picroft. Local (desktop or picroft) skill-communicate --> remote (picroft with skill-gpio8s). From local Picroft you are able to run remote picroft commands. It just work with GPIO1 switch relay

Requirement

• local Picroft - skill-communicate

• remote Picroft - skill-gpio8s or skill-gpio8s-lcd

Installation

Step 1.

Create a public/private keys with “ssh-keygen” (ENTER through everything):

user@host:~/.ssh$ ssh-keygen -t rsa

Generating public/private rsa key pair.

• Enter file in which to save the key (/home/toly/.ssh/id_rsa): [ENTER]

• Enter passphrase (empty for no passphrase): [ENTER]

• Enter same passphrase again: [ENTER]

• Your identification has been saved in /home/user/.ssh/id_rsa.

• Your public key has been saved in /home/user/.ssh/id_rsa.pub.

• The key fingerprint is: 66:fd:11:ca:2d:21:b9:73:c1:b6:fa:1d:b2:2c:71:cd

At this point the public and private keys should be created and saved into “~/.ssh” directory:

user@host:~/.ssh$ ls -l  
total 20  
-rw------- 1 user group 1675 2009-03-10 14:18 id_rsa  
-rw-r--r-- 1 user group 392 2009-03-10 14:18 id_rsa.pub  
-rw-r--r-- 1 user group 8642 2009-03-10 12:10 known_hosts    

Step 2.

Add identity to the local ssh authorizer with “ssh-add”.

If you “entered” through the “Enter file in which to save the key (/home/toly/.ssh/id_rsa)” in the previous step, then your identity file should be “id_rsa”:

user@host:~/.ssh$ ssh-add id_rsa

Otherwise replace “id_rsa” with the file you chose to save your identity in.

In case of a friendly “Could not open a connection to your authentication agent.” error message, start “ssh-agent” as:

'eval ssh-agent' 
and re-run “ssh-add”.

Step 3.

Copy the public key to the remote host ( server ) under “~/.ssh”:

From the step above “id_rsa.pub” would be the public key that needs to be copied to the remote system you would like to run commands on.

user@host:~/.ssh$ scp id_rsa.pub 
remoteuser@remotehost.com:~/.ssh/

From the remote host.

Step 4.

On remote host add this public key to “authorized_keys”:

remoteuser@remotehost:~$ cd ~/.ssh  
remoteuser@remotehost:~/.ssh~$ cat id_rsa.pub >> authorized_keys

Step 5.

Change “authorized_keys” permissions to allow only you to read/write it:

remoteuser@remotehost:~/.ssh$ chmod 600 authorized_keys  

Step 6.

Now you can run any command on the remote box from the local box with no password. Let's see what that remote box is running at:

user@host:~$ ssh remoteuser@remotehost.com  uname -a   
Linux remotehost 2.6.27-01-generic #1 SMP Thu Mar 21 10:34:21 UTC 2009 i686 GNU/Linux  
skill install - to local Picroft
msm install https://github.com/smolino/skill-communicate.git

Edit "__init__.py" and change the IP address ssh pi@your_ip_remote_address

Command

Hey Mycroft, send turn light on

Hey Mycroft, send turn light off

And mycroft responds:

sending turn light on

sending turn light off
