Confidential: Englishtown, Inc.. 2 September 2002 General Server-Side Requirements Firewalls Englishtown ASP is compatible with all firewall configurations that enable users to access the Internet using ports 80. Although not a requirement, it is preferred if the firewall is configured to allow streaming media as well. If Englishtown for LMS is deployed, Englishtown’s school content servers must be able to communicate with the customer’s LMS server over port 80 in order to send student data back to the LMS. Proxy Servers Englishtown uses Internet technologies that are fully compatible with proxy servers. In order to access Englishtown from a client using a proxy server, port 80 must be open bi-directionally, and port 443 (for HTTPS traffic) should be open inbound. In most cases, this is the standard configuration. In addition, with Microsoft Proxy Server the client should be able to authenticate using Basic Authentication (clear text authentication) or the client workstations must have MS Proxy Client installed to handle the proxy server authentication.
In the event that a client is having trouble accessing Englishtown through a proxy server, it is possible to bypass the proxy server using a static route for the Englishtown servers with the gateway set to be the firewall or Internet router. This will only work, however, if the Proxy server is not set up with separate inside and outside subnets.
Each corporate network has its own special configurations and security issues. Some points of Englishtown site are affected by these configurations, and the possible solutions vary from customer to customer, depending on the firewall and/or proxy configurations. As a general guideline, we can list the following points: -
All users must be able to “download” and “execute” ActiveX controls in their local workstations. The most part of these controls are installed on the first access, but periodically new controls (or new versions of old ones) can show up on the school site. -
If ActiveX “downloads” are blocked, but the user is still able to “execute” ActiveX controls, a manual installation can be performed. -
files “download” (wav, asf, wmf, etc.). Audio streaming permission is not needed. -
The Englishtown students must have access to all internet sites with names ending on “englishtown.com”, despite its host names or IP addresses. Modern firewall systems usually allow this kind of “domain-based” configuration, instead of old style “IP-based” access configuration. -
“englishtown.com” domain. -
The firewall and proxy systems must be configured to allow access to ports 80 and 443 of all Englishtown hosts (from inside to outside). If possible, access to port 1709 of external Englishtown hosts should be available as well. -
There is no special configurations for “return connections” (connections made from external hosts to internal client workstations). Usually the proxy system itself takes care of this. Firewall systems must allow “established return connections” from Internet to Intranet, as usual. The general guideline is: if you can simply browse Englishtown site pages, you are already done. -
The Englishtown Virtual Classroom (i.e. the Centra Symposium) client is compatible with packet filtering devices. Firewalls do NOT have to be reconfigured to support the EVC. Confidential: Englishtown, Inc.. 3 September 2002 -
The Englishtown Virtual Classroom client uses port 80 for HTTP events and port 1709 for audio, application sharing and user interactions. If port 1709 is not available (because, for example, the client is behind a firewall), the EVC client will automatically use tunneling over HTTP (port 80).
In some corporate networks, the users do not have enough privileges to install the EVC/Centra client automatically in their workstations. In these situations, a manual installation can be done. If the user (or corporation) already has the “SetupJ.exe” installation file, we recommend its installation in forehand, BEFORE the process described below. The user MUST have rights to install applications locally (usually, the user must be a “power user”). Installations made under different user profiles (even as “Administrator”) will not work as desired. In the same way, installations made using the “Run As” feature from Windows 2000 or XP will not work. The installation process is the following:
1) If the user already have the “SetupJ.exe” file, install it 2)
3)
Go to Englishtown web site, and log in. 4)
Click on the “Technical Check” link, and follow the instructions. Perform all tests (with the exception of “Voice Chat”), until you get the “Englishtown Virtual Classroom” test. 5)
During the EVC test, the user will receive the window shown below. Click on the link “CentraOne setup”.
6)
After the user receive the window below, he or she can download the “SetupJ.exe” file and install it. If they have already installed the Centra client at step 1, the will not you don’t need to download and install again. Click on “Launch CentraOne” button.
Confidential: Englishtown, Inc.. 4 September 2002
7)
If the Centra client loads and executes successfully, users will receive the warning window shown below. Click on “Yes”.
8)
You must receive the following window. Users should wait while the “Centra Client” version is updated.
Please note the following:
•
After the update, the EVC should open normally.
• This procedure should be executed only once – the first time a users tries to access EVC.
For questions or other information, please contact Englishtown directly.
Confidential: Englishtown, Inc.. 5 September 2002 Implementing Englishtown as an ASP Solution Overview Access to Englishtown’s web-based training in an ASP solution is provided on a licensed subscription basis. License codes provide individual users with unlimited access to all self-study materials as well as 24-hour live, teacher-led, discussion (if the teacher-led option is chosen).
In an ASP Solution, Englishtown is responsible for hosting all content, student data and performance tracking. Student access to the Englishtown training requires Internet access, either directly from the user’s desktop or through a web-connected Intranet server. Students will log-in, select courses, complete course work, take exams and track their results on the Englishtown servers. Manager reports will be accessible on the Englishtown site.
Englishtown’s proposal to implement an ASP solution at a customer would include the following steps: 1.
Develop Co-Branded Site: Englishtown would create and host an exclusive, co-branded Englishtown web site for use by the customer’s employees during the term of this agreement. The estimated completion time for this is three weeks. 2.
Distribution of Self-Study and Teacher-Led License Codes: Englishtown would provide the customer with a series of license codes which would be used by students to access training services on the Englishtown site. These license codes would have to be distributed to individual employees by the customer. We estimate approximately two- three weeks for this process. 3.
Build-Up Period: Englishtown and the customer would agree on a “build-up” period for students to enroll and begin studying. Typical build-up periods run from one to three- months, depending on the number of users.
[The rest of this page has intentionally been left blank] Confidential: Englishtown, Inc.. 6 September 2002 Englishtown Integration with an LMS Overview For organizations with a learning management system (LMS) in place who want a single entry point for all of their corporate training, we provide an easy integration using industry standard protocols. Englishtown can be integrated with any AICC-compliant LMS, such as Saba or Docent.
Under the integrated model, the customer hosts the LMS on one of its servers. The LMS serves as the primary e-learning ‘portal’ for and handles functionality such as the course catalog, user registration & authentication, tracking and reporting.
Please note that in an LMS integration, Englishtown continues to host the Englishtown school, including all self-study and teacher-led courses. Students launch Englishtown courses from the LMS course catalog and are automatically logged into Englishtown through a unified log on. Upon completing a unit of study in Englishtown, relevant student data is passed back to the LMS using the AICC industry-standard protocol. Project Estimates Englishtown will provide the technical resources needed to integrate the Englishtown School with the LMS using the AICC protocol. Billing for the cost and expenses incurred in this work would be in addition to the cost of any user licenses or content-access fees charged by Englishtown.
