(If you are participating in this tutorial at a conference click the "Create Slice" button for the project created for the tutorial.)

  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.

  1. If the key was uploaded successfully you should now see a message indicating success, and see a key in your SSH Keys list on your Profile page. To return to the add resources page click on Slices in the upper right-hand corner, and click on your slice name in the list. Then skip to step 17.
  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.

Generate Passphrase

  1. If the key was generated successfully you should now see a message indicating success, and see the key pair in your SSH Keys list. Click on Download Private Key, and save the key to your machine. It is suggested that you save the key as "~/.ssh/geni_key". If you use a different path or filename, you will need to alter future commands which use the key, to include your chosen path and filename.

Generated SSH Key

  1. In a terminal set the local permissions on the private key file by issuing the command
      chmod 0600 ~/.ssh/geni_key
  1. To return to the add resources page click on Slices in the upper right-hand corner, and click on your slice name in the list.
