Generating SSH keys and adding to GitHub
In order to work with a Github account remotely, you must prove ownership of the account. This is done with SSH keys. This cheat sheet describes how to generate public/private keys on the linux command line and set the public key to a Github account.
Generate a local SSH pair of keys using the following command
ssh-keygen -t rsa -b 4096 -C "firstname.lastname@example.org"
The SSH key pair is generated as two files: secret and public. The file can also be named. Set an optional passphrase or skip it by hitting enter twice. Using a password is more than recommended on a shared machine.
Copy only the public key
To add it to a Github account. Go on "Settings" in your profile and click on "SSH and GPG keys" from the side menu.
Finally, set the directory and file permissions on the local machine
chmod 700 .ssh chmod 600 .ssh/id_rsa chmod 644 .ssh/id_rsa.pub
List public and private keys
ls -l ~/.ssh/
