Current status

Targeted release: Not Specified
Last updated: December 14, 2011
Percentage of completion: 100% (tentative, subject to LEAP-authentication testing. Codewise, it seems to be complete. Obviously, any bugs/enhancements are not being considered here).

Detailed Description

WPA/WPA2-Enterprise Networks are just another kind of networks, requiring secured-authentication. This feature helps connect to such networks, which require authentication following the RADIUS protocol.

Benefit to Sugar

This is an extension to the sugar-capability, to connect to wireless-networks. This feature has been originally requested from Australia deployment.

Scope

This is an isolated change. Non-completion of this feature will just prevent the users from connecting to WPA/WPA2-Enterprise networks.

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)

Install "freeradius" rpm package
- sudo yum install freeradius
Stop the server (if running)
- sudo killall radiusd
Modify "/etc/raddb/clients.conf", to include the name of the network access-point/router. Sample files are present at
Modify "/etc/raddb/users", to configure a username-password pair for authentication. Sample files are present at
Fedora 17 users, please run the following command, before starting the radius server:
- sudo mv /etc/raddb/modules/dhcp_sqlippool ~
Start the server, by issuing the following command:
- sudo /usr/sbin/radiusd -X &

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).

Use-Cases That need to pass (thanks Sridhar Dhanapalan for the exhaustive list)

Network should connect, provided the credentials are correct (base-case).
Thereafter,
- network should auto-connect, when XO reboots.
- network should auto-connect, when XO resumes from being suspended.
- network should auto-connect, when XO wakes up from Automatic Power Management.
- network should auto-connect, when the wirless radio is turned off, and then turned on again.

Dependencies

There are no external dependencies. This feature is just an addon, with just another network-type being added to the list of "connectable" networks.

Contingency Plan

None necessary, revert to previous release behaviour.

Documentation

Discussions are on, on the "sugar-devel-" and "dextrose-" mailing lists.

Release Notes

There are no changes in ABIs/APIs, configuration or data file formats. Also, there are no upgrade concerns.

 == 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?''
+This is an extension to the sugar-capability, to connect to wireless-networks.
+This feature has been originally requested from Australia deployment.
-''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?''
+This is an isolated change. Non-completion of this feature will just prevent the users from connecting to WPA/WPA2-Enterprise networks.

 == 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?''
+There are no external dependencies. This feature is just an addon, with just another network-type being added to the list of "connectable" networks.
 == 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.''
+None necessary, revert to previous release behaviour.
 == 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.''
+Discussions are on, on the "sugar-devel-" and "dextrose-" mailing lists.
 == 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.''
+There are no changes in ABIs/APIs, configuration or data file formats.
