XenDesktop7 HowTo Citrix Admin published on 2013-10-22 included in XenApp and XenDesktop 7.XCitrix released the first part of the Project Avalon with the codename Excalibur at Citrix Synergy 2013 in [Los Angeles](http://maps.google.com/maps?ll=34.05,-118.25&spn=0.1,0.1&q=34.05,-118.25 (Los%20Angeles)&t=h “Los Angeles”). Project Avalon was announced as the Giant step into Cloud Transformation, so what is it really? Citrix invested heavily in their existing product infrastructure with the question: “What could XenDesktop & XenApp look like if we re-imagined them for the cloud era?”. If Citrix started over, how would they design virtual apps & desktops for the mobile cloud era?
Features not in XD7 release Citrix Admin published on 2013-10-21 included in XenApp and XenDesktop 7.XThe following features are not currently in or are no longer supported by XenDesktop 7 and related releases. Features not in XenDesktop 7 Secure ICA encryption below 128-bit — In previous releases, Secure ICA could encrypt client connections for basic, 40-bit, 56-bit, and 128-bit encryption. With this release, Secure ICA encryption is available only for 128-bit encryption. Direct SSL connections — In previous releases, administrators could configure SSL Relay support connections to Web Interface and between an SSL-enabled plug-in and each server.
Netscaler and Netscaler Gateway difference Citrix Admin published on 2013-10-18 included in NetScalerCitrix NetScaler refers to their Application Delivery Controller, or ADC, line of products, while the NetScaler Gateway, formerly know as the Citrix Access Gateway, or CAG, is primarily used for secure remote access. You basically buy a ‘normal’ NetScaler but with limited functionality due to the NetScaler Gateway License you upload. NetScaler ADC’s are capable of doing much more than ‘just’ remote access, they can be used for load balancing and HA, content switching, application (SSL) offloading, application firewalling, cloud connectivity, hybrid cloud solutions and (a lot) more.
HTTP to HTTPS Redirect Netscaler link Citrix Admin published on 2013-10-12 included in NetScalerBelow process is in normal option, when you login to netscaler, click configuration tab, expand traffic management, expand load balancing, then virtual servers: step 1 create a vip(ex, name, citrix.company.com, ip, 172.16.1.1), with http protocol(port 80), which means it accepts http requests(when users hit the netscaler link, http://netscaler.company.com, this vip receives it) and add a redirect url in it as https://netscaler.company.com. Dont add any services or service groups or any servers.
Configuring a Backup Load Balancing Virtual Server(Backup vserver) Citrix Admin published on 2013-09-27 included in NetScalerYou can configure the NetScaler appliance to direct requests to a backup virtual server in the event that the primary load balancing virtual server is DOWN or unavailable. The backup virtual server is a proxy and is transparent to the client. The appliance can also send a notification message to the client regarding the site outage. You can configure a backup load balancing virtual server when you create it, or you can change the optional parameters of an existing virtual server.
Configuring HTTP Compression Citrix Admin published on 2013-09-27 included in NetScalerBy default, compression is disabled on the NetScaler ADC. You must enable the feature before configuring it. If the feature is enabled, the ADC compresses server requests specified by compression policies. To configure HTTP compression, do the following: Configure compression actions Configure compression policies Bind the compression policies to global bind points or to virtual servers Optionally, configure global compression parameters Enabling HTTP Compression Compression can be enabled for HTTP and SSL services only.
Redirecting Client Requests to an Alternate URL Citrix Admin published on 2013-09-27 included in NetScalerIn the event that a load balancing virtual server of type HTTP or type HTTPS goes DOWN or is disabled, you can redirect requests to an alternate URL by using an HTTP 302 redirect. The alternate URL can provide information about the status of the server. You can redirect to a page on the local server or a remote server. You can redirect to a relative URL or an absolute URL.
Method, Monitors and Persistence in Load Balancing Citrix Admin published on 2013-09-26 included in NetScalerThere are three important components of setting up a load balancing configuration, namely monitors, methods and an optional parameter called persistence. When setting up the load balancing, different combinations of these three components can give different results. When you set up load balancing, a default monitor is always attached to the configuration. In simple terms, a monitor is used to keep a check on the status of the services. On the other hand, configuring the type of method tells NetScaler how the incoming requests would be routed to the load balanced servers.
Netscaler Deployment Topology Citrix Admin published on 2013-09-26 included in NetScaler PS CourseA NetScaler appliance resides between the clients and the servers, so that client requests and server responses pass through it. In a typical installation, virtual servers configured on the appliance provide connection points that clients use to access the applications behind the appliance. In this case, the appliance owns public IP addresses that are associated with its virtual servers, while the real servers are isolated in a private network. It is also possible to operate the appliance in a transparent mode as an L2 bridge or L3 router, or even to combine aspects of these and other modes.
What is SSL and SSL Offloading Citrix Admin published on 2013-09-26 included in NetScaler PS CourseWhat is ssl? SSL (Secure Sockets Layer) is a standard security technology for establishing an encrypted link between a server and a client—typically a web server (website) and a browser; or a mail server and a mail client (e.g., Outlook). SSL allows sensitive information such as credit card numbers, social security numbers, and login credentials to be transmitted securely. Normally, data sent between browsers and web servers is sent in plain text—leaving you vulnerable to eavesdropping.
