1. On your local machine (laptop), check whether you already have SSH keys at default location ~/.ssh.
    • On MacOS terminal:
      • The permission for the ~/.ssh folder should be 700 (drwx------).
      • The permisison for the private key ~/.ssh/id_rsa should be 600 (-rw-------).
      • The permission of the public key ~/.ssh/id_rsa.pub should be 644 (-rw-r--r--).
    • On Window Git Bash, the following permission could also work (thanks to Ranjana):
      • The permission for the ~/.ssh folder can be 755 (drwxr-xr-x).
      • The permisison for the private key ~/.ssh/id_rsa can be 644 (-rw-r--r--).
      • The permission of the public key ~/.ssh/id_rsa.pub can be 644 (-rw-r--r--).
  2. On the teaching server, put the same pair of keys under ~/.ssh.
    • The permission for the ~/.ssh folder should be 700 (drwx------).
    • The permisison for the private key ~/.ssh/id_rsa should be 600 (-rw-------).
    • The permission of the public key ~/.ssh/id_rsa.pub should be 644 (-rw-r--r--).
    • The authorized_keys file should contain the public key (cannot duplicate) and its permission should be 600 (-rw-------).
  3. (optional) If no SSH keys yet, generate a pair of SSH RSA keys
    • Method 1: generate keys on MacOS Terminal or Windows Git Bash. Follow instructions in lecture notes.
    • Method 2: Use RStudio to generate keys. Tools -> Global Options… -> Git/SVN. Using either method, make sure keys are in the default location ~/.ssh/

  4. Register an account on GitHub Student Developer Pack, using ucla.edu email.

  5. Upload the public key to GitHub account.

  6. Create a private repository called biostat-203b-2020-winter and add Hua-Zhou and juhkim111 as your collaborators with write permission. Gitignore R.

  7. Set up seemless SSH connection between (1) laptop, (2) teaching server, and (3) GitHub.

  8. Log in to the RStudio server on teaching server http://server.ucla-biostat-203b.com:8787, using the username and password on the teaching server.

  9. On teaching server, initialize a project from GitHub within RStudio. Make sure use the Git address instead of the HTTPS address. You can also initialize a project using RStudio on your laptop. But HW1 is mostly about Linux and most easily done on teaching server.

  10. Commit the Rproj file.

  11. Create a new branch called develop.

  12. Within develop branch, create folder hw1 and start working on hw1sol.Rmd. Commit hw1sol.Rmd.

  13. Basics of RMarkdown.

  14. QA and hints for HW1.
