Recognizing Citrix Web Components

  • The three tiers (or components) of NFuse are a Web server, a Citrix server farm, and an ICA Client device.

  • NFuse is essentially a Web-enabled Program Neighborhood.

  • Only those applications published in the Farm Management Scope will appear in NFuse.

  • The NFuse Web Extensions are what install the NFuse Java objects.

  • The Web Site Wizard will help create a customized Web site to fit a company's needs.

  • All Web sites created with the Web Site Wizard include code for Web-based ICA Client installation.

  • An ICA Client device is comprised of a Web browser and an ICA Client.

  • An ICA file contains parameters needed by the ICA client to launch an ICA session.

Identifying NFuse Features and Components

  • On a firewall, the following inbound TCP ports need to be open for communication to occur for: 80 for HTTP, 443 for SSL, and 1494 for ICA sessions.

  • To specify an alternate address on a Citrix server, you must run the altaddr command.

  • To specify an alternate address on a Web server, you must replace the substitution tag [NFuse_IPV4Address] with [NFuse_IPV4AddressAlternate].

  • NAT is used in conjunction with alternate addresses.

  • Ticketing allows authentication to occur without passing credentials within an ICA file.

  • SSL Relay is a secure communication created between the Web server and the Citrix server farm.

  • NFuse Java objects are COM compliant.

  • 128-bit RC5 encryption allows secure communication to occur from the ICA Client device to the Citrix server farm.
