Nstrace
Nstrace is a NetScaler packet capture tool. Nstrace dumps packets in the native NetScaler format. These trace files have an extension of .cap and can be analysed with WireShark. You can use specific filters in WireShark as normal to filter through captured data or specify filters using the NetScaler CLI. This allows you to only capture traffic of interest.
Enhanced Authentication Feedback introduced since v10.1 is a NetScaler option disabled by default which provides more information to the end user about the reason for an authentication failure. By default when a user authenticates to as an example NetScaler Gateway and fails, the Incorrect user name or password message returned is the only reason NetScaler will give.
