OK, so we’ve given you a running computer. How do you access it?
The two thing you’ll need are the network name of your computer, which you can get from the spreadsheet linked to in the hackmd; and the ‘cicese.pem’ file that we’ve given you on the hackmd.
Copy the name, and connect to that computer with ssh under the username ‘ubuntu’, as follows:
First, move your private key file from wherever you downloaded it onto your Desktop.
Next, start Terminal (in Applications... Utilities...) and type:
chmod og-rwx ~/Desktop/cicese.pem
to set the permissions on the private key file to “closed to others”.
Then type:
ssh -i ~/Desktop/cicese.pem ubuntu@ec2-???-???-???-???.compute-1.amazonaws.com
(but you have to replace the stuff after the ‘@’ sign with the name of the host).
Here, you’re logging in as user ‘ubuntu’ to the machine ‘ec2-174-129-122-189.compute-1.amazonaws.com’ using the authentication key located in ‘cicese.pem’ on your Desktop.
You should now see a text line that starts with something like
ubuntu@ip-10-235-34-223:~$. You’re in! Now type:
sudo bash
cd /root
to switch into superuser mode (see: http://xkcd.com/149/) and go to your home directory.
This is where the rest of the tutorials will start!
To log out, type:
exit
logout
or just close the window.
