2 Apt Users
Registering for an account is quick and easy. Registering doesn’t cost anything, it’s simply for accountability. We just ask that if you’re going to use Apt for anything other than light use, you tell us a bit more about who you are and what you want to use Apt for.
Users in Apt are grouped into projects: a project is a (loosely-defined) group of people working together on some common goal, whether that be a research project, a class, etc. Apt places a lot of trust on project leaders, including the ability to authorize others to use the Apt. We therefore require that project leaders be faculty, senior research staff, or others who are relatively senior positions.
2.1 Register for an Account
To get an account on Apt, you either join an existing project or create a new one. In general, if you are a student, you should join a project led by a faculty member with whom you’re working.
If you already have an account on
Emulab.net, you don’t need to sign
up for a new account on Apt—
2.1.1 Join an existing project
To join an existing project, simply use the “Sign Up” button found on every Apt page. The form will ask you a few basic questions about yourself and the institution you’re affiliated with.
An SSH public key is required; if you’re unfamiliar with creating and using ssh keypairs, we recommend taking a look at the first few steps in GitHub’s guide to generating SSH keys. (Obviously, the steps about how to upload the keypair into GitHub don’t apply to Apt.)
Apt will send you email to confirm your address—
watch for it (it might end up in your spam folder), as your request won’t be processed until you’ve confirmed your address.
2.1.2 Create a new project
You should only start a new project if you are a faculty member, senior research staff, or in some other senior position. Students should ask their advisor or course instructor to create a new project.
To start a new project, use the “Sign Up” button found on every Apt page. In addition to basic information about yourself, the form will ask you a few questions about how you intend to use Apt. The application will be reviewed by our staff, so please provide enough information for us to understand the research or educational value of your project. The review process may take a few days, and you will receive mail informing you of the outcome.
Every person working in your project needs to have their own account. You get to approve these additional users yourself (you will receive email when anyone applies to join.) It is common, for example, for a faculty member to create a project which is primarily used by his or her students, who are the ones who run experiments. We still require that the project leader be the faculty member, as we require that there is someone in a position of authority we can contact if there are questions about the activities of the project.
Note that projects in Apt are publicly-listed: a page that allows users to see a list of all projects and search through them does not exist yet, but it will in the future.
2.1.3 Setting up SSH access
The first step to setting up ssh access to Apt is to generate an ssh key pair.
**For Windows users:**
A good option for a Windows ssh client is to make use of putty:
To generate and manage ssh keys with putty:
https://www.ssh.com/ssh/putty/windows/puttygen
**For Linux and Mac OS users:**
To generate and manage ssh keys:
https://www.ssh.com/ssh/keygen/
Once you have generated an ssh key pair, you need to upload the public key into the Apt portal:
Log into the Apt portal. Once you are logged in: Click on your username (top right), select "Manage SSH keys" and follow the prompts to load the ssh public key.
The next time you instantiate an experiment, your ssh public key will be loaded onto all (ssh capable) nodes in your experiment, allowing direct access to these nodes using an ssh client.
2.1.4 Setting up X11
Experiment based graphical user interface (GUI) interaction on Apt often require X windows, so you might find it useful to have an X-server running on the laptop/desktop you use to access resources on Apt.
**For Windows users:**
Various options are available, for example:
https://sourceforge.net/projects/vcxsrv/
**For Mac OS users:**
