HP Tru64 UNIX and TruCluster Server Version 5.1B-5 Patch Summary and Release Notes (March 2009)

Previously, the sorting of audit data on single CPU systems was unnecessary. This
changed, however, when the capability for auditing these network events was
introduced. Now, to view these network events in order with respect to other events,
you must sort the data on a single CPU system. To do this, use the audit_tool -S
command.
3.2.2.13 new_wire_method Tunable Attribute Retired
The tunable attribute new_wire_method has been retired. After you install this kit,
setting new_wire_method to either 0 or 1 will no longer affect your system.
3.2.2.14 Stopping Daemons May Speed Administration Performance
When using AdvFS administration commands, the advfsd and smsd daemons rescan
filesets, domains and volumes for system information. Depending on the number of
filesets, domains, and volumes, you may experience a pause — sometimes quite long
— between the commands.
If you experience this performance degradation, you may want to stop advfsd (required
for dtadvfs, the AdvFS graphical user interface) and smsd (required for SysMan
Station) daemons before running multiple AdvFS administration commands.
See “New Variable Aids Performance of AdvFS Administration Commands” for
information on disabling the advfsd daemon at boot time.
To temporarily stop the daemons enter the following commands:
# /sbin/init.d/advfsd stop
# /sbin/init.d/smsd stop
To restart the daemons enter the following commands:
# /sbin/init.d/advfsd start
# /sbin/init.d/smsd start
3.2.2.15 sendmail Application Size/Length Limits Can Cause Problems
When upgrading older releases of sendmail, be aware that the 5.1B version of
sendmail has MIME header/content marker size limits and message header length
limits. These limits have been added to stop a Denial of Service (DoS) attack on the
sendmail server. The values default to the following:
MIME Header Length Size = 2048 characters
MIME Content Marker Size = 1024 characters
The MaxHeadersLength value is the maximum message header length allowed and
its size can be installation dependent (the value defaults to 8192 bytes).
Some legacy applications may be affected by this security addition if the application
is sending mail messages with long lines of text and no new-line markers. These
limitations may cause sendmail to insert a carriage return at these boundaries.
