Nelson Esteves has moved through the ranks as part of the Citrix Technical Support team. He started out as a level one support engineer on the XenApp team, and now is an Escalation Engineer for the NetScaler and Advanced Access Gateway (AAG) support team. Nelson will be presenting the following sessions at Citrix TechEdge during Citrix Summit and Citrix Synergy 2009: End-to-end virtualization with Citrix Delivery Center, with a focus on Citrix Access Gateway, Enterprise Edition (AGEE), and then his in-depth session will cover .
Q. How has AGEE improved from a support perspective over the past year?
Nelson: AGEE has evolved to a bigger and better product. With the 9.0 release we are able to meet most of users demands such as full Microsoft SharePoint Integration as well as Branch Repeater acceleration. From a support perspective, the new filtering capabilities of network tracing on the appliance is great not to mention the ability for more granular control such as choosing packet type and size.
Q. What AGEE and Citrix Delivery Center tips will attendees learn at your session this year?
Nelson: During the breakout session, attendees will learn with great detail how pre and post-authentication scans work and how to configure them properly. They’ll also learn how AGEE integrates with XenApp via Web Interface. I’ll show what’s involved on the login process to Web Interface and how Smart Access works in the background. In addition to all that they’ll learn how to successfully decrypt a network trace and how to troubleshooting SSL errors when launching a published application via a pre-recorded troubleshooting video. The CDC presentation will explain how AGEE integrates with XenDesktop as well as Web Interface and NetScaler.
Q. What new tools or techniques are you using to troubleshoot NetScaler?
Nelson: The new filtering system when taking network traces was a great addition, and it made troubleshooting a lot faster since we can now select what we want to filter instead of having to handle very large network trace files.
Q. What types of cases have you worked on this past year? Why?
Nelson: I have handled cases related to VoIP issues via the VPN, SSL Errors when launching applications, Microsoft SharePoint integration issues, and several others. Most of the VoIP issues had to do with the software being used since it didn’t have an option for VPN configuration. We need to make sure the call manager server receives the VPN user Intranet IP and not its local IP. SSL Errors were due to clients either not having the proper certificates installed or misconfiguration on the AGEE or Web Interface (missing STA, wrong STA URL, missing STA port, etc.). SharePoint integration has been challenging since the release of 9.0, but now we have corrected all the errors we have encountered.
