Walking inside of your computer

SSH

Walk into other computers. We set up the Pis to have individual IP address and allow SSH. Secure Shell is a 'cryptographic network protocol for operating network services securely over an unsecured network.'

SSH into the teacher's computer

  • ssh pi@sfpc-12
  • Are you sure you want to continue connecting (yes/no)? yes
  • Password: morepoetry
  • All computers' passwords are the same
  • Now you are inside of the teacher's computer. Be mindful.
  • change directory to, cd folder-poetry
  • cd mailbox
  • view the letter by cat letter.txt
  • Write a letter to the teachers by nano letter-from-mimi.txt or your name

Set up your mailbox

  • cd folder-poetry
  • mkdir yourname-mailbox
  • cd yourname-mailbox
  • such as mimi-mailbox

SSH into your neighbor's computer

  • ssh pi@sfpc-x
  • x is the number of your neighbor's computer. ask for consent.
  • navigate your neighbor's folders. Understand the folder structure.
  • Change Director to folder-poetry
  • Send an 'electronic mail' by creating a file by
nano letter.txt
  • Ctrl + O to save
  • Ctrl + x to exit nano
  • To view the file, cat letter.txt
  • ctrl + d to get out of ssh

address

  • /home/pi is the same as ~/

Move files inside of your computer

mv ~/Desktop/image.jpg ~/folder-poetry/mailbox

Send files to your friends mailbox

  • scp stands for secure copy
  • download an image to your mailbox
  • or, to move an existing image from the desktop,
mv ~/Desktop/filename.jpg ~/folder-poetry/mimi-mailbox
  • to send to a friend
scp ~/folder-poetry/mimi-mailbox/image.jpg pi@sfpc-12:~/folder-poetry/mailbox/

From students A's Pi 'sfpc-1' to student B's Pi 'sfpc-2' Student B would write this command to copy something from A's box into their box

- scp pi@sfpc-1:~/folder-poetry/a-mailbox/letter.txt ~/folder-poetry/b-mailbox
