What's new for V5R4

This topic highlights the changes made to the iSeries™ NetServer™ topic collection for V5R4.

iSeries NetServer has the following performance and scalability enhancements and new functions for V5R4:

• Threading support

  To increase performance, iSeries NetServer now supports the use of pools of threads to process client requests. The new QZLSFILET job handles threaded requests.

• Opportunistic locks

  Clients have the option of caching application requests to reduce network traffic and server overhead.

• LAN Manager password hash

  When enabled, it allows Windows^® clients to authenticate with the less secure (not case sensitive) LAN Manager password hash even if the more secure (case sensitive) NT password hash is also provided and does not match.

• Message authentication/signing support

  For more secure communications between the client and server, iSeries NetServer now supports connection request signing. Signing requests provide improved protection from the following types of attacks: connection hijacking, downgrade attack, rogue server and spoofing by counterfeit servers, active message modification, and replay attacks. See Requiring clients to sign requests for more information.

• Windows messenger service

  The system can be configured to alert users who are running Microsoft^® Messenger or similar service using the iSeries Navigator graphical user interface (GUI).

What's new as of 31 January 2007

iSeries NetServer enables Windows Vista clients to access i5/OS shared directory paths and shared output queues.
