HP Tru64 UNIX and TruCluster Server Version 5.1B-6 Patch Summary and Release Notes

Autoloader Firmware Upgrade Changes WWND
A firmware upgrade to v1.50 or N14r on the 1x8 Autoloader causes the WWID to change. As a
result, the existing device associated with the media changer is no longer accessible. For complete
details see the Customer Advisory available at:
http://h30097.www3.hp.com/unix/erp/c00753663.html
Some Smart Array Errors May Not Be Recoverable
When booting your system you may see a message similar to the following:
Smart Array at ciss(1) not responding - disabled.
A system reboot may be able to re-enable the hardware. If that does not work, you need to call
Field Service and have the unit repaired.
Do Not Use dxarchiver to Verify Bootable Tape
Do not use dxarchiver command to verify a bootable tape. Instead, use the mt and restore
commands as follows:
# mt fsf 1
# restore -i <device>
The first command skips the first file on the tape.
When preparing for a btcreate session, verify the size of the file system to ensure that you
have sufficient tape volumes, depending on the maximum storage capacity of your tape device.
The btcreate command prompts you to load a new tape volume if it runs out of storage space.
Label the tapes in sequence.
securenets File Requires localhost Entry
If the /var/yp/securenets file is in use as part of NIS, it must contain the following localhost
entry:
255.255.255.255 127.0.0.1
If the /var/yp/securenets file is used without a localhost entry you will see severe delays
on logins. See ypserv(8) for more information.
SIA sialog Use Limitation Required
The Security Integration Architecture (SIA) sialog logging process is only intended for use in
debugging SIA problems. It should not be enabled for extended periods of time. Doing so can
cause login delays or other problems.
Use the audit subsystem to monitor authentications on the system, not the sialog process
To disable sialog debug logging, delete the /var/adm/sialog file. For more information,
see the sialog(4) and sia_log(3) reference pages and the Tru64 UNIX Security Programming manual.
Note that when used in a TruCluster Server cluster, the sialog file is a cluster-wide file.
Change to executable_data Attribute Requires Running Script
Prior to setting the tunable attribute executable_data to a non-zero value, you must run the
following script:
# /usr/sbin/javaexecutedata
Potential Security Vulnerability Identified
The industry standard TCP specification, RFC793, has a vulnerability in which an attacker can
reset established TCP connections using the TCP RST (Reset) or SYN (Synchronize) flags.
These packets need to have source and destination IP addresses that match the established
connection as well as the same source and destination TCP ports.
