The repository for the assignment is public and Github does not allow the creation of private forks for public repositories.

The correct way of creating a private frok by duplicating the repo is documented here.

For this assignment the commands are:

Create a bare clone of the repository. (This is temporary and will be removed so just do it wherever.)

git clone --bare [email protected]:usi-systems/easytrace.git

Using SSH through airplane WiFi that blocks port 22

Many aircraft that offer wifi only permit access to machines on port 80/443, the standard http(s) ports. If you want to SSH, you have to set up an intermediate machine that hosts the SSH service on either port 80 or 443. An easy (and free) way to do this is via a Google free-tier micro instance. These instances have a 1 GB transfer ceiling per month, but so long are you are only transmitting textual data a few days per month, this limit should not be easily exceeded. Set up one of these VMs via the Google Cloud console, and select CentOS 7 as the disk image. Make sure that you allow http/https traffic on the instance, the two checkboxes in the Firewalls section of the VM settings. Optionally, set a static external IP address for your server in the VM config, in case you don't want to look up the IP each time. Then, ssh into the new VM (the IP address will be listed as the "external IP" in the list of instances) and edi

Go to https://script.google.com
Create a New Project
Replace the Code.gs file it creates for you with the javascript below (copy/paste)
Save the script
Go to Triggers (looks like an alarm clock on left-hand side)
Create a Trigger that acts every 10 minutes and calls filterNGPVANSpam
You'll need to authorize this script to act on your behalf, which may require that you use the scary "Advanced" section to allow the script to read/write to your email inbox.
