Finalmente disponibile Citrix Netscaler 10.5!


netscalerAttendevo questa release più delle altre specialmente dopo i problemi avuti con la parte Java negli ultimi mesi: finalmente è disponibile per il download NetScaler 10.5 e la novità più evidente è la nuova UI completamente scritta in HTML5.

Più di una volta sono rimasto bloccato nel dover velocemente configurare alcune parti di Netscaler 10.1: gli avvisi di java error, errori di protezione, lentezza ecc… diciamo…era il monento di dare un cambio radicale! La colpa è della piattaforma Java, che con le ultime evoluzioni ha creato non pochi problemi anche su webapp di configurazione di altri dispositivi tra cui san, switch e firewall.

The NetScaler graphical user interface (GUI) has been enhanced to provide a better user interaction experience. It now provides you with a workflow-based experience, which guides you through the entire configuration. The configuration settings have been classified as basic and advanced for some features. The NetScaler ADC configuration utility and NetScaler Gateway configuration utility has also been reimplemented in HTML. As a result of these enhancements, the GUI does not display pop-up dialog boxes for most features and you no longer need Java Runtime Environment (JRE) to access these features through the GUI.

netscaler105

Con la versione 10.5 Citrix non ha migliorato soltanto la GUI, sotto ci sono veramente tantissime novità: andiamo a vedere il riassunto del change-log ufficiale

AAA Application Traffic

  • AAA-TM can now be configured to authenticate users with an external RADIUS or LDAP authentication server at a specific FQDN instead of only at a specific IP.
  • Unlocking Locked-Out User Accounts
  • NetScaler Default Expressions support for authentication subsystem
  • Extracting SAML Attributes from Keytab
  • Web-based Authentication
  • Strong Encryption Support in Kerberos KCD
  • Renegotiate Support for Certificate-based Policies
  • Using a Responder HTML Response Page to provide Customized Error Responses
  • KCD Performance Improvements
  • NetScaler as SAML IDP
  • Authentication Server Stickiness
  • Responder After AAA
  • With previous versions of the NetScaler ADC, OWA 2010 connections did not timeout because OWA sends repeated keepalive requests to the server to prevent timeouts, which interfered with single sign-n and posed a security risk. AAA-tm now supports forced timeouts that ensure that OWA 2010 sessions timeout after the specified period of inactivity.

AppFlow

  • The process of collecting the load time and render time of web pages has been simplified by including the clientSideMeasurements parameter as part of the add appflow action command.
  • NetScaler ADC now exports AppFlow records to a set of collectors if the transaction responses are served from the NetScaler cache.
  • Indication for End of Transaction]
  • Cisco RISE Integration

Cisco RISE Integration

  • Configuring RISE with NetScaler ADC and Cisco Nexus 7000 Switches.

Cluster

  • You can now add a failover interface set (FIS) on the nodes of a NetScaler cluster. On the cluster IP address, specify the ID of the cluster node on which the FIS must be added as follows:
  • A NetScaler cluster can now be configured to run with less than (n/2 + 1) number of nodes online.
  • Spotted VIP for NetScaler Gateway clusters. Spotted VIP functionality has been expanded to enable clustering for NetScaler Gateway.
  • MPTCP is now supported on a NetScaler cluster.
  • Layer2 Mode Support in a Cluster

Compression

  • Specifying a Vary Header Value

Content Accelerator

  • Content accelerator is a NetScaler feature that you can use in a Citrix ByteMobile T1100 deployment, to store data on a Citrix ByteMobile T2100 appliance. This saves bandwidth and provides faster response times, because the NetScaler does not have to connect to the server for repeated requests of the same data.

Content Switching

  • Multiple Port Content Switching Support for HTTP and SSL Virtual Servers

  • If the length of URLs displayed in the Web Insight reports is very long, you can enable the trim URL functionality to remove the query string from the URL.
  • Data record logs provide detailed information about appflow records that NetScaler Insight Center collects from NetScaler ADCs.
  • You can now configure the ICA session timeout value for inactive sessions on the NetScaler Insight Center configuration tab.
  • The active sessions data on the dashboard now include the following metrics:

    Client IP: IP address of the client

    Server IP: IP address of the server

    NetScaler IP: NetScaler IP address

  • You can now customize NetScaler Insight Center reports to display the metrics that you want, and you can specify bar graphs or line graphs.
  • HDX Insight Center reports now support the following metrics:

    -Client side zero window size event: This counter indicates how many times the client advertised a zero TCP window.

    -Server side zero window size event: This counter indicates how many times the server advertised a zero TCP window.

    -Client side fast RTO: This counter indicates how many times the retransmit timeout was invoked on the client-side connection.
