HP Tru64 UNIX and TruCluster Server Version 5.1B-6 Patch Summary and Release Notes
New Control Option for /usr/sbin/audit_tool Command
This kit provides the following new control option for the /usr/sbin/audit_tool command:
# /usr/sbin/audit_tool -. [path]
This option causes audit_tool to use [path] for the archive/recovery directory that
contains archived audit logs, thereby overriding the directory specified in the audit log, which
by default is /var/audit.
Change to envmond Improves Performance on Some Systems
This patch kit modifies the Environmental Monitoring daemon, envmond, to improve performance
on systems with many sensors.
With the default monitor period of envmond (ENVMON_MONITOR_PERIOD), systems having
large number of sensors may experience a performance degradation. The changes to envmond
address this problem by polling sensors at a lower frequency.
Release Notes Introduced in Prior Kits
The release notes in this section were included in previous patch kits.
Authentication Choice Affects sftp Transfer Rate
The performance of secure FTP (sftp) will be always less than ftp due to the authentication
and encryption involved in sftp communication. The transfer rate of sftp depends on the type
of authentication it employs. You can achieve better transfer rate performance by choosing the
Message Authentication Code (MAC) algorithm hmac-md5 for authentication, but at the cost of
security. The default MAC is hmac-sha1, which is more secure than hmac-md5. See sftp(1) for
information about secure FTP and ssh2_config(4) for information about supported MACs and
ciphers.
Tru64 UNIX Rebranding Results in File Changes
As a consequence of the rebranding of Tru64 UNIX from the Compaq name to HP, the following
files have changed:
• version.abbrev_vendor from COMPAQ to HP
• version.banner from Compaq Tru64 UNIX to HP Tru64 UNIX
• version.vendor from Compaq Computer Corporation to Hewlett-Packard Company
The .mrg..sysconfigtab file has been modified to incorporate these changes into the generic
sysconfig subsystem in the /etc/sysconfigtab file.
If the rebranding of HP Tru64 UNIX version information impacts any applications or layered
products, you can manually change generic system version attributes. See the sysconfigtab(4) and
sys_attrs_generic(5) reference pages for more information on how to modify generic system version
attributes.
Insight Manager Components DUMP Core
Some Insight Manger components included in Tru64 UNIX Version 5.1B-4, such as cpq_mibs
and the config_hmmod, and sysman_hmmod daemons, may core dump during reboots.
You can correct this problem by installing the latest version of the Insight Manager. At the time
Version 5.1B-4 was released, the most current Insight Management Agents kit was Version 3.6.
You can download this version from the HP Insight Management Agents for Tru64 UNIX website:
http://h30097.www3.hp.com/cma/
If you have not installed Version 3.7 and the Insight Manager processes do not run after rebooting
your system, restart them using the Insight Manger startup scripts.
