3.1 New Release Notes
The release notes in this section describe issues you may encounter and, when available,
provide workarounds you can use.
3.1.1 New Keyword Added to sshd2_config Configuration File for sshd daemon
The new keyword, AuthInteractiveFailureRandomTimeout, adds a random
delay to the existing AuthInteractiveFailureTimeout delay. For information on
AuthInteractiveFailureTimeout, see the sshd2_config manpage .
The AuthInteractiveFailureRandomTimeout keyword can take a value from 0
to 100 (in seconds). The default is 2 seconds. To disable
AuthInteractiveFailureRandomTimeout, specify a value of 0. When a non-zero
value is specified for this keyword, a random number of milliseconds up to the number
of seconds specified multiplied by 1000 is added to the server delay specified by
AuthInteractiveFailureTimeout.
3.1.2 New Option to Ignore Processor Set Boundaries
A new command-line argument, lockinfo, has been added to solve issues related to
processor-set boundaries. The new command takes -ignore_pset as an optional
argument and when passed, enables the lockinfo command to ignore processor-set
boundaries. However, it will honor the RAD (Resource Affinity Domain) set boundaries
if the –rad option is used.
