A GSLB configuration consists of a group of GSLB entities on each appliance in the configuration. These entities include the following:
GSLB Sites GSLB Services or service groups GSLB Virtual Servers Load Balancing or Content Switching Virtual Servers ADNS Services DNS VIPs GSLB Sites A typical GSLB setup consists of data centers, each of which has various network appliances that may or may not be NetScaler appliances. The data centers are called GSLB sites.
By default client drives, usb drives, com ports, printers etc redirection from user’s devices to citrix applications is allowed. On Windows machines, printer redirection works. They can see their local printers in citrix application sessions. But in macbook it doesnt work by default. Follow below process to make it work in macbook.
Solution: Create a new Citrix policy with the below settings.
Printer Policy in Citrix Studio Next login to the VDA server and follow the article: https://support.
ICA Only: If you don’t have enough Citrix Gateway Universal licenses installed for all of your Gateway users, then we can use ICA Only option. This option disables SmartAccess and VPN features but does not require any additional licenses. Note: most Citrix ADC Editions come with built-in Gateway Universal Licenses.
If we dont need smartaccess, then we can use ica only option to provide apps and desktops to users.
ICA Proxy: Citrix Gateway has an ICA Proxy feature that authenticates the user, proxies HTTP traffic to StoreFront, and then proxies ICA traffic to VDAs.
NetScaler SmartControl:
SmartControl allows administrators to define granular policies to configure and enforce user environment attributes for Citrix Virtual Apps and Desktops on Citrix Gateway. SmartControl allows administrators to manage these policies from a single location, rather than at each instance of these server types.
SmartControl is implemented through ICA policies on Citrix Gateway. Each ICA policy is an expression and access profile combination that can be applied to users, groups, virtual servers, and globally.
Storefront Aggregation
A core functionality of StoreFront is the ability to aggregate and de-duplicate “common” application and desktop resources from multiple Citrix Virtual Apps and Desktops (CVAD) Sites. This functionality is commonly referred to as multi-site aggregation. Duplicate applications and desktops are identified based on matching Application Display Name and Application Category properties. This functionality has been available in the console as of version 3.5 and was previously a config file edit.
Connection multiplexing is a method of reusing connections to avoid the overhead on the server that comes with establishing new connections for each request. Connection multiplexing support in Citrix ADC ensures that server connections are efficiently reused, which results in dramatically reduced SSL/TLS load on back-end servers.
Q: What is the connection multiplexing feature of the NetScaler appliance? A: The connection multiplexing feature is the core of the NetScaler appliance functionality.
What is NTFS Stream All files on an NTFS volume consist of at least one stream - the main stream – this is the normal, viewable file in which data is stored. The full name of a stream is of the form below.
<filename>:<stream name>:<stream type>
The default data stream has no name. That is, the fully qualified name for the default stream for a file called “sample.txt” is “sample.txt::$DATA” since “sample.
Mostly, all the companies that use Citrix NetScaler Gateway, want to customize their NetScaler Gateway URL, like changing the logo, background image, Titles, etc. All of this can be done with a theme and Citrix has a direct way of doing this, by creating something called a portal theme. You can go to this option by navigating to Netscaer – Citrix Gateway – Portal Themes. Create a theme, modify it as per your requirement and apply it to your NetScaler Gateway VIP.
What if your company has application servers hosted across multiple data centers and wants to distribute traffic based on load, server proximity, persistence requirements, or needs disaster recovery?
NetScaler GSLB Citrix NetScaler features a solution called Global Server Load Balancing (GSLB) that addresses these challenges. NetScaler GSLB is a DNS-based solution that employs various technologies to distribute resources across multi-site data center locations.
How DNS Works (Traditional Method) With ordinary DNS, when a client sends a domain name system (DNS) request, it receives a list of IP addresses of the domain or service.
NetScaler NSIP shows a white page on the browser while using a custom theme: Note: Below steps work only when using a custom theme.
/var/netscaler/gui/admin_ui - folder will have files and folders required to load the GUI admin portal when you connect to NSIP via the browser. When you upgrade your firmware to the next version, files and folders in this admin_ui folder will be upgraded as this is a system folder, which is created by NetScaler.
