Summary

This feature helps connect to WPA/WPA2-Enterprise Networks, in a sugar-environment.

Owner

Current status

  • Targeted release: (SUGAR_VERSION)
  • Last updated: (DATE)
  • Percentage of completion: XX%

Detailed Description

Expand on the summary, if appropriate. A couple of sentences suffices to explain the goal, but the more details you can provide the better.

Benefit to Sugar

What is the benefit to the platform? If this is a major capability update, what has changed? If this is a new feature, what capabilities does it bring? Why will Sugar become a better platform or project because of this feature?

Make sure to note here as well if this feature has been requested by a specific deployment, or if it has emerged from a bug report.

Scope

What work do the developers have to accomplish to complete the feature in time for release? Is it a large change affecting many parts of the distribution or is it a very isolated change? What are those changes?

UI Design

There is no impact on the workflow; it's just that the user will have to enter way more parameters for conencting to a WPA/WPA2-Enterprise networks. Please see "User Experience" section for details.

How To Test

Setting up a RADIUS server (on a dedicated machine)

Setting up the access-point / router

  • Connect the access-point/router, with the RADIUS server machine, through a ethernet cable.
  • Through the RADIUS server machine, open the browser, type in the access-point/router IP address, and configure it for WPA/WPA2-Enterprise authentication. A sample screenshot is presented below



  • Note that, you may only need to enter the "Radius Server IP Address" ("192.168.1.3" in the screenshot). The "Radius Server Port", and "Share Secret" are the default ones (at least for a default setup of freeradius).




Connecting a client - TLS-based authentication

  • Make sure you have three certificates - user-certificate, ca-certificate, private-key - before you proceed. One way to get these certificates is as follows:
    • Go to the RADIUS server machine, and navigate to "/etc/raddb/certs"
    • Run the following commands
      • sudo make client.pem
      • sudo chmod 0644 client.p12
      • sudo chmod 0644 ca.pem
      • Transfer "client.p12" and "ca.pem" to a USB drive.
      • Use this USB drive, in the subsequent steps.
  • Navigate to the "Neighbourhood view" on the XO.
  • Click on the network-icon, and enter the parameters, as seen in the following screenshot



  • NOTES
    • If either of "User Certificate", or "Private Key" is in ".p12" format, both these entries should be EXACTLY equal, since the ".p12" certificate contains both.
    • For entering the "User certificate", "CA certificate" and "Private Key", you will be taken to the "Journal-Chooser". You may use the certificates that were retrieved earlier.




Connecting a client - LEAP-based authentication

  • Help required !!!!
  • We have not been able to set-up a LEAP-authentication-supported access-point / router.
  • Any CISCO guys !!??




Connecting a client - TTLS-based authentication

  • Navigate to the "Neighbourhood view" on the XO.
  • Click on the network-icon, and enter the parameters, as seen in the following screenshot (thanks to Anish, for showing me this minimal configuration).



  • NOTES
    • The above configuration is a minimalistic configuration. However, the parameters-cum-secrets modal-dialog, has been modelled on nm-applet.




Connecting a client - PEAP-based authentication

  • Navigate to the "Neighbourhood view" on the XO.
  • Click on the network-icon, and enter the parameters, as seen in the following screenshot.



  • NOTES
    • The above configuration is a minimalistic configuration. However, the parameters-cum-secrets modal-dialog, has been modelled on nm-applet.

User Experience

  • The network-icon for a WPA/WPA2-Enterprise Network, will appear just like any other network-icon, in the Neighbourhood-view.
  • When a user clicks on the icon, she will be asked for parameters-cum-secrets (much more in number, but just like any other network-type).
  • Upon clicking the 'ok' button (and provided all sufficient-and-correct parameters are provided), the connection will be made. This can be confirmed by the tray-icon.
  • Once a connection is made, user need not re-enter parameters-cum-secrets next time (reboot) onwards. The parameters-cum-secrets will automatically be read from sugar-settings-file (connections.cfg) (just like any other network-type).

Dependencies

What other packages (RPMs) depend on this package? Are there changes outside the developers' control on which completion of this feature depends? In other words, does your feature depend on completion of another feature owned by someone else or that you would need to coordinate, which might cause you to be unable to finish on time? Other upstream projects like Python?

Contingency Plan

If you cannot complete your feature by the final development freeze, what is the backup plan? This might be as simple as "None necessary, revert to previous release behaviour." Or it might not. If your feature is not completed in time, we want to assure others that other parts of Sugar will not be in jeopardy.

Documentation

Is there upstream documentation on this feature, or notes you have written yourself? Has this topic been discussed in the mailing list or during a meeting? Link to that material here so other interested developers can get involved.

Release Notes

The Sugar Release Notes inform end-users about what is new in the release. An Example is 0.84/Notes. The release notes also help users know how to deal with platform changes such as ABIs/APIs, configuration or data file formats, or upgrade concerns. If there are any such changes involved in this feature, indicate them here. You can also link to upstream documentation if it satisfies this need. This information forms the basis of the release notes edited by the release team and shipped with the release.
