Adding your SSH key to ssh-agent

1. Start the ssh-agent in the background.

eval "$(ssh-agent -s)"

2. Add SSH keys to ssh-agent

• On Mac

ssh-add -K ~/.ssh/id_rsa

• On Windows

ssh-add ~/.ssh/id_rsa

Add SSH key to your Github account

• Follow the steps below https://help.github.com/articles/adding-a-new-ssh-key-to-your-github-account/

Note When running pbcopy < ~/.ssh/id_rsa_STUDENTNAME.pub, please make sure you are copying the correct student public key

Create a Git Config File

1. Open git config file with Nano(easier to use) or Vim

nano ~/.ssh/config 

If no config file, create config file

touch ~/.ssh/config

• Nano and Vim commands

2. The git config file should look like this

Host me.github.com
HostName github.com
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa_STUDENNAME1

Host github.com
HostName github.com
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa_STUDENTNAME2

3. Save config file

• If in Nano, hit ctrl + x then type y to save
• If in Vim, hit ctrl + ;, then type wq to save

4. To test, clone a repo, git add, git commit, then git push to see if it works
