kit. You may need to baseline your system if you have manually changed
system files on your system. The dupatch utility provides the baselining
capability.
2) The patch in this ERP kit does not have any file intersections with any
other ERP available at this time for this product version.
3) This ERP kit will NOT install over any Customer Specific Patches (CSPs)
which have file intersections with this ERP kit. Contact your normal
Service Provider for assistance if the installation of this ERP kit is
blocked by any of your installed CSPs.

> mkdir -p /tmp/CSPkit1
> cd /tmp/CSPkit1
> <copy the kit to /tmp/CSPkit1>

2 Special Instructions
SPECIAL INSTRUCTIONS for Tru64 UNIX V5.1B Patch C2094.00
This patch adds a new keyword to the sshd2_config
configuration file for the sshd2 daemon. The new
keyword, AuthInteractiveFailureRandomTimeout, adds
a random delay to the existing
AuthInteractiveFailureTimeout delay. See the
sshd2_config man page for information on
AuthInteractiveFailureTimeout.
The AuthInteractiveFailureRandomTimeout keyword can
take a value from 0 to 100 (in seconds). The default
is 2. 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.
