= Tmix Resources Setup - Portal = This page describes how to reserve resources for the [wiki:GeniTmixTutorial Tmix Tutorial] using GENI Portal. 1. Open a browser window and '''go to the GENI Portal''': Click [http://portal.geni.net] 2. Click on the '''Use GENI''' button. [[Image(welcomeGeni.png, 30%)]] 3. Next you will be asked which institution or organization you are affiliated with. If your institution is listed as a suggested selection, click on the name of your institution. Otherwise, '''enter the name of your institution or organization''' in the text box. As you type, a list of selections will appear. Select your institution or orgainzation, then '''click continue'''. [[Image(partner.png, 35%)]] 4. 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'''. 5. If your credentials are accepted, you will be taken to your GENI Portal home page. 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.) [[Image(createSlice.3.png, 10%)]] 6. 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. [[Image(CreateNewSlice.png, 30%)]] 7. 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. [[Image(SliceCreated.png, 50%)]] 8. 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. If you have already set up your SSH key in Portal, '''skip to step 16'''. [[Image(NeedKeys.png, 60%)]] 9. If you already have an SSH key you wish to use, '''click Upload an SSH key''', and '''continue with step 10'''. Otherwise, click Generate and Download SSH keypair, and skip to step 12. 10. 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/geni_key.pub) Add an optional description, if you like, and then click '''Upload'''. 11. 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 16'''. 12. 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. [[Image(GenerateSSH_Password.png, 50%)]] 13. 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. [[Image(GeneratedSSH.png, 50%)]] 14. In a terminal set the local permissions on the private key file by issuing the command {{{ chmod 0600 ~/.ssh/geni_key }}} 15. 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. 16. 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 minute experiment 2 nodes”''' resource specification and the '''Utah ProtoGENI''' aggregate. Click the '''Reserve Resources''' button. [[Image(resource.png, 40%)]] 17. 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. [[Image(resources.png, 30%)]] 18. 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 pc339.emulab.net. You will need the hostame of both nodes later in this tutorial. You can write them down, or return to this details page later. Click on the '''Slice ''' link at the top of the page to return to the Slice page. Click on''' Resource Status''' 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. [[Image(status.png, 30%)]] Once the nodes are ready you should see the status change to READY. [[Image(status2.png, 30%)]] You now ready to log in to your nodes and run Tmix.
