Tmix Resources Setup - Portal

This page describes how to reserve resources for the Tmix Tutorial using GENI Portal.

  1. Open a browser window and go to the GENI Portal: Click
  1. Click on the Use GENI button.

  1. Next you will be asked which organization you are affiliated with. If your organization is listed as a suggested selection, click on the name or logo of your institution. Otherwise, begin typing the name of your school or organization in the text box. As you type, a list of matches will appear. Select your organization, then click continue.

  1. You will be asked to enter credentials for your institution or organization. This is likely the same username and password that you use for other services at your institution. Enter your credentials and then click to continue.
  1. If your credentials are accepted, you will be taken to your GENI Portal home page. Geni utilizes SSH keys to grant access to the network nodes. If you have already generated and shared SSH keys with Geni Portal, skip to step 14, otherwise continue with step 6.
  1. Hover over your name in the upper right-hand corner of the page, and then click SSH Keys.
  1. If you already have an SSH key you wish to use (not recommended), click "upload an SSH public key", and continue with step 8. Otherwise, click generate and download an SSH keypair, and skip to step 10.
  1. Click Choose File, and select the public SSH key file you wish to use for GENI, and click Open. (Your key may be stored at this default location: ~/.ssh/ Add an optional description, if you like, and then click Upload.
  1. If the key was uploaded successfully you should now see a message indicating success. Now click the Home tab, and skip to step 14.
  1. To generate a new SSH key pair, type a Passphrase in the text box, and re-type it in the Confirm Passphrase text box. Click Generate SSH private key to proceed. Please remember your chosen passphrase. You will need it later.

  1. If the key was generated successfully you should now see a message indicating success, and you should now see the key pair in your SSH Keys list. We recommend you download the private key to your machine so you can use an SSH client to connect to the nodes. To do so, Click on Download Private Key, and save the key to your machine. Save or move the key to the "~/.ssh/" directory if using Linux. If you use a different path or change the filename, you will need to alter future commands which use the key, to include your chosen path and filename.

  1. Unless you are using Windows, In a terminal set the local permissions on the private key file by issuing the command:
      chmod 0600 ~/.ssh/id_geni_ssh_rsa
  1. Click on the Home tab to continue
  1. Under the “My Projects” section you will find a list of projects you are a part of. Click on the "Create Slice" button of the project you wish to work in. (If you are participating in this tutorial at a conference click the "Create Slice" button for the project created for the tutorial.)

Create Slice button

  1. Choose a name for your slice. This name will be public, and needs to be unique among all the slices in your project. To ensure uniqueness it is recommended that the slice name begin with your username (used above to log in) and be followed with a descriptive string. For example, if your username was smith, you might choose a slice name of smithTmix. Enter your slice name and a description of the slice (optional) in the text boxes, and then click the Create slice button.

Create New Slice Page

  1. Assuming the slice was successfully created, you will be taken to the slice page. Here you can add and delete resources, access various tools, and view the status of the slice. Click on the Add Resources button to add resources to your slice.

Slice Created Page

  1. If you have not already uploaded or generated and downloaded an SSH key for use with GENI you will see a red box with a message to that effect. (see steps 6 through 13)
  1. On the Add resources page you can choose resources to add to your slice from a specific aggregate. For this tutorial select the “Tmix 10 min experiment” resource specification. If you are completing this tutorial at a conference select the aggregate you were assigned to use by the person in charge of the tutorial. Otherwise, select any of the instageni aggregates or ProtoGENI. Click the Reserve Resources button.

Add Resources Page

  1. The next page will indicate that it is reserving the requested resources. It may take a few minutes. Once the resources are allocated you will see a detailed list of the resources.

Resource Details

  1. Before leaving this page, note the Login line of each of the two nodes listed. Each login line will contain the hostname of the node, for example, as well as the port number. You will need both the hostame and port of both nodes later in this tutorial. You can write them down, or return to this details page later. Now, click on the Slice <slicename> link at the top of the page to return to the Slice page. Scroll down to the Manage Resources section, and click the Resource Status button to view the detailed status of the resources. Likely the status page will show that the hosts are not yet ready. The resources have been allocated, but the nodes are being imaged, and booted. This process can take up to 10 minutes.

Status before nodes are ready

Click Refresh Status until the status changes to READY.

Status ready screen

You now ready to log in to your nodes and run Tmix. Please continue to the next step back at the main Tutorial page.
