<h1 class="topictitle1">Terminology for service tools user IDs and passwords</h1>
|
|
<div><p>The following definitions will help you understand the service
|
|
tools user IDs and passwords information.</p>
|
|
<div class="section"> <dl><dt class="dlterm">Data Encryption Standard (DES)</dt>
|
|
<dd>A type of reversible encryption algorithm. DES uses two pieces of information,
|
|
the data to be encrypted and the key to use to encrypt the data. If you supply
|
|
DES with the encrypted data and the encryption key, you can decrypt the data
|
|
and get the original data.</dd>
|
|
<dt class="dlterm">dedicated service tools (DST)</dt>
|
|
<dd>Dedicated service tools (DST) are service functions that are available
|
|
only from the console and can run when the operating system is not available,
|
|
as well as when the operating system is available.</dd>
|
|
<dt class="dlterm">default password</dt>
|
|
<dd>When the password is the same as the service tools user ID. For example,
|
|
the IBM-supplied QSECOFR service tools user ID is shipped with a default password
|
|
of QSECOFR.</dd>
|
|
<dt class="dlterm">disabled password</dt>
|
|
<dd>A password that has been marked as being unable to sign on with it because
|
|
you have had too many invalid sign-on attempts. You cannot sign on using a
|
|
disabled password.</dd>
|
|
<dt class="dlterm">expired password</dt>
|
|
<dd>A password that has not been changed within 180 days or more. You can
|
|
still sign on using an expired password, but you must change the password
|
|
at the time of sign-on.</dd>
|
|
<dt class="dlterm">functional privileges</dt>
|
|
<dd>The ability to grant or revoke access to individual service tools functions.</dd>
|
|
<dt class="dlterm"><span class="keyword">i5/OS™</span> user
|
|
profiles</dt>
|
|
<dd>User profiles that are created with the <span class="cmdname">Create User Profile (CRTUSRPRF)</span> control
|
|
language (CL) command or iSeries™ Navigator, and are used to sign on to the
|
|
operating system.</dd>
|
|
<dt class="dlterm">locked</dt>
|
|
<dd>The mechanism used to control programmatic changes to certain functions.
|
|
If a function is "locked", it cannot be changed through normal user interfaces.
|
|
You must unlock it in order to change it.</dd>
|
|
<dt class="dlterm">password levels</dt>
|
|
<dd>Within DST, a password level can be set. The password level specifies
|
|
whether Data Encryption Standard (DES) or Secure Hash Algorithm (SHA) encryption
|
|
is used when storing passwords. The default level is DES.</dd>
|
|
<dt class="dlterm">Secure Hash Algorithm (SHA)</dt>
|
|
<dd>An encryption method in which data is encrypted in a way that is mathematically
|
|
impossible to reverse. Different data can possibly produce the same hash value,
|
|
but there is no way to use the hash value to determine the original data.</dd>
|
|
<dt class="dlterm">service functions</dt>
|
|
<dd>Service functions are specific capabilities within service tools. Service
|
|
functions are typically used for problem analysis and problem solving, often
|
|
with the assistance of IBM<sup>®</sup> support. Examples of service functions include Licensed
|
|
Internal Code trace, Licensed Internal Code log, and the display, alter, dump
|
|
function.</dd>
|
|
<dt class="dlterm">service tools</dt>
|
|
<dd>Functions that are used to configure, manage, and service important operational
|
|
aspects of the server. Service tools allow you to do such tasks as configuring
|
|
your logical partitions, managing your disk units, and troubleshooting
|
|
problems. Service tools are accessed through dedicated service tools (DST),
|
|
system service tools (SST), and other service-related CL commands. Improper
|
|
use of service tools can damage your server.</dd>
|
|
<dt class="dlterm">service tools device IDs</dt>
|
|
<dd>Used with LAN console to control access to the system.</dd>
|
|
<dt class="dlterm">service tools server</dt>
|
|
<dd>The service tools server allows you to use your PC to perform service
|
|
tools functions through TCP/IP.</dd>
|
|
<dt class="dlterm">service tools user IDs</dt>
|
|
<dd>A user ID that is required to access DST, SST, iSeries Navigator (for logical partitions
|
|
and disk unit management), and Operations Console. Service tools user IDs
|
|
are created through DST or SST, and they are separate from user profiles.</dd>
|
|
<dt class="dlterm">system service tools (SST)</dt>
|
|
<dd>System service tools (SST) allow you to access service functions from
|
|
operating system. Service tools are accessed using the <span class="cmdname">STRSST (Start
|
|
SST)</span> CL command.</dd>
