Today brings a new development drop. The major new functionality in this drop is an almost complete redesign of the UI. The new UI has a lot of features that will make the supplicant easier to use. Among them is a configuration wizard, an "at-a-glance" list of available SSIDs, and a quick connect option from the tray icon. This is just a few of the new features the UI redesign will expose. Please give it a try, and let us know what you like, don't like, etc.

Work on the supplicant has been progressing at a reasonable pace. Since the last release, we have discovered and fixed a few more bugs, added some new features, and changed some of the underlying engine to work better across a range of machines. It is finally time to release a new development version that can be used to see the work that has been going on. To that end, we are proud to release the development (a.k.a. Unstable) version 2.1.1.

There are a couple of new features that are worth pointing out. First, we have enabled support for EAP-GTC. In our test environment, we have been able to successfully do a PEAP-GTC authentication using RSA SecurID tokens. Second, is network prioritization. The supplicant will now try to automatically connect to the best network that is currently available. Third, is the ability to have the supplicant disconnect the sessions when the user logs off. Fourth, is opportunisitic key caching. (Sometimes also called Proactive Key Caching) This will allow the supplicant to roam to new access points in a shorter amount of time, since a reauthentication may not be needed. And last, but certainly not least, is removal of the reliance on WMI. This last feature is something that most people won't notice. But, if you had problems running the older supplicant versions, this change will probably resolve those problems.

XSupplicant version 2.0.1 has been released. This release fixes bugs that have been found since the 2.0.0 release. It does not contain any new features.

In addition to the new release, there has been a lot of work taking place on the next version. First, the project management committe (PMC) decided to rename the codename from SeaMonkey to SeaAnt and to accept a letter ordering for all future codenames. So, along with SeaAnt, the two releases that will follow it are "SeaBadger", and "SeaCow". Second, the roadmap for SeaAnt has been approved by the PMC. Two versions are available. The "executive summary" version can be found here, a longer version with (really) rough timelines can be found here. Third, we have started to work on various pieces of documentation. All of the documentation will be included in future source drops, in addition to the documentation links in the SourceForge project.

Last, but not least, we have also decided to move away from CVS to Subversion. HEAD development (SeaAnt and beyond) is now using subversion. While making this cut over, we also took the opportunity to rearrange the source tree a little. There are now three main modules :

• xsupplicant -- The XSupplicant engine (GPL/BSD licensed)
• xsupplicant-ui -- The XSupplicant UI (GPL licensed)
• xsupplicant-build -- Install packaging and build scripts (GPL/BSD licensed)

The Open1X group is pleased to announce the release of the 2.0.0 version. The 2.0.0 release marks the point that we have frozen the development on this branch and find it stable for our use. All new development will now be taking place on the next release with is code named "SeaMonkey". We do expect to release additional versions of 2.0, but they will only be bug fix releases, there will be no additional functionality added to 2.0.

That said, there were a couple of new features added between the 1.9.8 release and the 2.0 release. They were generally small additions that addressed usability and clarity issues. Some of these additions include a plug-in that can be used to gather data to help us solve problems that people may have. By right-clicking the tray icon, you can new select "Create Trouble Ticket". This will create a zip file that contains information that you should attach to any bugs that get filed. Another addition is the ability to import trusted root certificates in to the proper certificate store, and some fixes to how certificate chains are handled. We have also added a significant number of wireless utilities that we are able to detect and help users disable.

Because the work in this development cycle has been focused on getting a working version for Windows, we suggest that Linux users continue to use the 1.2.8 version. However, Linux users should also be aware that getting the Linux version caught up with the changes that were added to Windows is at the top of our priority list. Once we have something that is working for us, we will start to put out development releases again.

XSupplicant 1.9.8 has been unleashed. As with the other 1.9 versions the latest development release comes complete with a bunch of bug fixes. Notable bugs that have been fixed include a protocol driver fix that could cause a blue screen when used with really old network interface drivers. And removal of the EKU restrictions on root CA certificates. (In English : You can use ANY root CA certificate now. Even if it doesn't have the special attributes that the Microsoft supplicant requires.) The on-line help file has also been finished. Other issues that have been resolved are listed in the changelog.

It has been a few weeks since the last development release. But, it is time for another one. Along with the usual set of small bugs that were fixed, there are a few larger more noteworthy bugs that are fixed in this version. This development release brings us a fix for running on Windows XP Home, control over how and when log files get rolled, and better support for hidden networks. Check out the change log for a better list of what has changed.

29 Oct 2007
There have been a few changes over the last week, all leading up to this latest release. First, we added the ugly button at the top of the web page to help people get to the download area more easily. Our web designer is working on something that blends in to the over-all look of the site, but until then the ugly button should do the trick. Second, the new version has a VERY important fix in it. This version should be able to properly do PEAP authentication again the Microsoft IAS server that is included with Windows 2003 Server. So, if you have had problems authenticating against IAS, please give this latest build a try and let us know if you have any problems.

A new development release was put out on the servers a couple of days ago, but I am just now getting around to updating the web site. This release includes several bug fixes for issues that people have reported, and one new feature. The new feature is a change in how priorities work on different types of adapters. Wired adapters are no longer listed in the priorities window, since the priorities didn't do anything on wired anyway. An a new option is available in Advanced Settings. The "Wired Default" setting allows you to select a wired Connection to always try to connect to whenever the service is started. You should check out the changelog to see most of the bug fixes that were made.

There has also been a lot of work going on in CVS HEAD on the next version. The next version is code named "Sea Monkey". The feature set for Sea Monkey is still unclear. But, there has been work done already to port the UI to Linux, and Mac OS X. There are still some issues to hammer out before it is usable on those platforms, but we are getting there.

Which brings me to one of the things we are working on behind the scenes. We are starting work on developing a wish list of features. We will be soliciting feature requests from OpenSEA members directly, but we also want to hear from the rest of the community. What features would you like to see added to the supplicant? We plan to compile the list of requested features on a web site, and then scratch them off the list as we go.

07 Oct 2007
We have started to get feedback on the various development releases that we have put out so far. As a result, we have some additional work to do. To this end, we have decided not to put out a new release this week. However, today we released the source code to the UI. We plan to resume weekly releases next week.

01 Oct 2007
This release is a little late in coming, but it is finally here. The latest development release contains additional bug fixes, and stability improvements. In addition to the normal weekly release, we have released the promised test sheet. Please take a moment to fill out all of the information you can about your test scenario. The information will be used to help us develop a matrix of tested configuations, and help us continue to improve the supplicant.

22 Sept 2007
In keeping with the "roughly once a week" development releases, we have released the latest development refresh. This refresh has some important stability fixes in it. Most of the people that have been using early versions of this release report that it has solved many of the early problems they had seen. Grab the latest version here.

16 Sept 2007
The latest development refresh of the supplicant has been released. This refresh includes bug fixes for various issues we discovered during the last week of testing. It is also now aware of Windows going to sleep, and waking up. This awareness gets rid of some error messages that could pop up when a machine was put to sleep, or brought out of sleep. Please download the latest version, give it a try, and report any issues that you may find. The latest development release can be found here.

10 Sept 2007
An issue with the installer for the latest development version has been discovered. This issue will prevent anyone from being able to install the supplicant on a machine that doesn't already have the latest Visual C++ redistributable package on it. This issue has been fixed, and the offending installer has been replaced with a new one. If you downloaded the file xsupinst-v1.9.1.exe you have the installer with the bug. Please download xsupinst-v1.9.1.070910.exe to get the fixed version.

IEEE 802.1x is a port based authentication protocol. It can be used in *any* scenario where one can abstract out the notion of a port. It requires entitie(s) to play three roles in the authentication process: that of an supplicant, an authenticator and an authentication server. The diagram below shows the basic scenario.
