Notes
This presentation contains an overview of what is new in Network Station Manager (NSM)
Version 2 Release 1 ( V2R1).
The objective is to highlight only the items that are new in V2R1, without providing in depth
information, so that one can get a quick glance at only the differences with the previous
release.
We provide one chart, two at the most, on each of the items listed here.
In general, only the NSM graphical configuration interface, the installation process and the
3270 and 5250 emulators look and feel have not changed. Everything else has been
significantly changed, in particular
a brand new kernel
a totally new graphical desktop
a new browser
new PD tools
new ICA client
new hardware

Notes
Since the beginning of the Network Station in 1996, there has been a steady evolution of
the NSM functional content that has been based on the same hardware platform and the
same operating system.
With Version 2, a significant new step is taken by moving to a new operating system and
introducing a new hardware platform, while maintaining compatibility with all previous
models except for the Series 100.

Notes
This chart taken from a Hardware Overview presentation on the Marketing CD
summarizes the characteristics of all the models supported by Version 2 Release 1.
Generally, we can think of the Series 2200 as the X86 equivalent to the Series 300 PPC
model and the Series 2800 as the equivalent of the Series 1000 PPC, although it has more
flexible I/O capabilities.

Network Computer Division10
Notes
This chart provides you with a glance at all the important enhancements in V2R1.
First, note that all the V1R3 AF functions have been retained
The major enhancements are
a new kernel
a new graphical desktop
a new current Netscape browser that includes an internal JVM and the Java Plugin
a new Java environment, which is the full JDK at the 1.1.8 level
an ICA client that has been significantly enhanced, along with the addition of a Remote
Application manager
Miscellaneous Emulator enhancements, including a VTxxx emulator with the same look
and feel as the 3270/5250 emulators
Miscellaneous plugin and Java based viewers
Support for 16-bit color palette
and the Introduction of a true kiosk mode
The Network Station Manager support has been extended to include new configuration
items. The underlying configuration files have been totally changed and reduced in number
and a new command line tool for batch or interactive changes to the configuration profiles
is now available.
The release supports the Microsoft Windows NT, AIX and AS/400 platforms and is can
coexist with the previous release on the same server.

Network Computer Division12
Notes
Certainly the most evident part of the new look is the new graphical desktop shown here with a launchbar
on the left on which appear either application icons or folders containing application icons.
Scroll up/down arrows are used when more folders are available on the launchbar than can be displayed.
Pulldown controls are available on folders to bring up the pulldown menu of applications contained in the
folder. On this chart, the Extras folder is expanded to show the applications that it contains. Notice that the
applications shown here are supplied by default:
Audio Player
Calculator
Calendar
File Manager
Paint
Real Player
Text Editor
Video player
The window management is similar to Windows, with Windows style decorations for minimizing and
maximizing windows, tiled windows and minimized icons.
The launchbar also contains a memory indicator at the top. The color indications on the memory indicator
gives a visual indication of the memory usage; a click on the indicator expands to show the actual amount
of memory used and of free memory.
At the bottom is a digital clock and the three indicators for Logout, Help and Locking the station.

A right mouse click on the desktop brings up a menu from which one can minimize all
windows, or specify the placement of the minimized icons, or constrain the windows so
that they do not disappear behind the launchbar.
One can also change the background wallpaper (Color Theme), lock the keyboard and
logout and exit.

Notes
The new browser is Netscape Communicator 4.5 full product, including:
NC Navigator browser, NC Messenger e-mail, and Newsreader, Dynamic HTML,
JavaScript 1.3
It also includes new JavaScript-based customization capabilities, and an application
launcher capability to launch local native applications.
There are more translations and code pages, and the Kiosk support has been improved.
The Navigator uses its built-in JVM, not external JVM, and therefore provides compatibility
with other versions of Netscape. Sun's Java Plug-In provides ability to redirect applets to
the Network Station's JVM which is at a higher level.
The Navigator is able to run applets independently of the activity on the external JVM
which has been enhanced by IBM for Euro support and robustness.
Netscape Messenger has a new user interface and adds IMAP4 support to the existing
SMTP and POP3 support. LDAP Support for the address book is provided as well.

Network Computer Division18
Notes
The Java environment has been significantly enhanced in V2R1. The enhancements are
as follows:
More than one Java application can now be executed simultaneously
The browser (Netscape Communicator 4.5) now has an internal JVM and applets built for
any Netscape platform can be executed
Sun Microsystem's JDK 1.1.8 is provided to which IBM has added enhancements such as
memory management fixes, euro currency support, enhanced security and integration with
the Network Station's operating system.
The complete JDK is also provided instead of just the Java Run Time environment which
means that the Java compiler can be executed on the Network Station itself
Jave extensions such as JMF, Swing and javax.comm are provided
Two swappable JVM's are provided so that the latest JDK can be used for development
activities. The switch from one to the other is done through the use of an environment
variable.
The Java plug-in is provided to allow applets executed in a Netscape environment to use
the full function JVM of the Network Station instead of the Netscape JVM.
Finally, there is now support for signed applets and JAR files.

Notes
In V2R1, the ICA client has been enhanced with many additional features.
A Remote Application Manager, which is similar in function to the 'ICA Chooser' that
presents a list of servers to choose from, is now available on the desktop by default. The
system administrator can configure connection entries and users may also configure
connection entries, if that was enabled.
The ICA client now provide the Windows audio experience (wav, midi, etc.) and one way
audio mapping with audio compression
Secure ICA is available to provide a secure medium for running Windows applications . It
supports Citrix's Secure ICA option pack and end-to-end RSA RC5 encryption for the ICA
data Stream
Protocol Compression provides better response times over WAN connections
The NSM configuration has been enhanced to make it easier for System Administrators to

Notes
This shows the main Network Station Manager panel each for V1R3 (on the left) and V2R1
(on the right).
The visual differences are minor:
The setup task bar is the same but some of the submenus are different
The choice of level, System, Group, User or Workstation is now done on the main panel,
BEFORE choosing a task as opposed to after selecting a task. This avoids having to
choose a level after each selecting each task and therefore provides a better flow since
one usually chooses a level to work on first, and then tasks to configure.
However, even though the graphical interface has not changed much, lots of changes
have been made to the underlying functions.

Notes
These are the main to the Network Station Manager V2R1 application.
First, V2R1 can coexist with V1R3 on the same server because the root of each directory
structure is different
Configuration information from V1R3 config files can be migrated to V2R1 profiles
The NSM main menu is similar but the list and organization of the setup tasks have been
slightly modified
V2R1 now has configuration support for the desktop and launchbar, and this is a lot more
flexible than the V1R3 menu bar
The number of configuration files has been significantly reduced. There are now only 8
configuration profiles, including the override files and there is a single format (XML Extended markup language).
A command line interface is now provided to do either interactive or batch update of the
configuration files
Finally, the OMRON support from V1R3 has been removed
These are only the major changes. Many of the actual NSM panels have also had some
changes, but most of the fields are the same and their meaning has not changed.

Notes
The Network Station Manager Command Line interface (abbreviated NSMCL) is a utility
written in Java to make batch changes directly to the XML-based configuration profiles.
The user actually has the choice of two interfaces;
Configuration commands can be run directly from the command line
Or the user can use a graphical interface to enter the configuration commands
In addition, configuration change commands can be issued individually or a script file
containing many commands can be specified as the input file.
The scripting language used is SGML (Standard General Configuration Language) Text.

V2R1 has introduced true kiosk mode, while still making the previous mode that was used
in V1R3 available (called Suppressed Login mode). This chart highlights the differences
between these two modes?
In true kiosk mode:
There is no specific user identity, whereas there is a specific user in suppressed login
mode, even though the user himself did not enter a name, because the name was fetched
from a file.
Acces to the server must be read-only for all functions. Since there is no user identity, there
is no need to store user preferences for example.
Since there is no user identity, there is only system and group behavior that's applicable.
(default group since there is no real user)
Actually, the window manager is active but it is not apparent because the application runs
full screen without any borders
There is no desktop in true mode
There is only one application running (although some applications can actually launch
other applications
The application is autostarted in both cases, but more than one application can be
launched when in suppressed login panel mode.
In true kiosk mode, the application can be restarted if ended by the user (but not in
suppressed login panel mode).

Notes
This is a summary of some of the enhancement made to the emulator applications in
V2R1.
In general, full screen coverage is available and the readability improved with scaleable
fonts.
The applications now have more of a PC look and feel.
A VTxxx keyboard remapping facility has been added and the Help text has been
significantly augmented, including keyboard functions.
SSL version 3 telnet support has been added as well as editable macros.
The IP host name can also now be used as a session name.
For the VTxxx emulator, convergence toward 5250 / 3270 standard User Interfaces has
been started with the following functions added:
A Graphical Keyboard remapper
Some Online Help Text
The ability to specify miscellaneous preferences
Configuration options controls in NSM
Standard printer support for ASCII, PS and PCL datastreams

Network Computer Division32
Notes
The changes from V1R3 relative to printing are minor changes for the most part.
Serial ports up to 18 can now be defined on a Series 2800 because there are 2 native
ports and possibly two PCI cards that can each support 8 serial ports. On a Series 1000,
there is one native port and a multiple serial port adapter card allowed four more for a total
of 5 ports.
In NSM, the configuration panels for printer settings now have a Serial Options settings
(which used to be done using override files in V1R3) and the ASCII options for DBCS have
been removed.
The browser print dialog has changed slightly and the print selector panel has also
changed slightly but the functionality is the same.
The lpr (or nclpr which is equivalent) command can be used on the command line to
initiate a print request.
A print monitor window is available to display the current print jobs scheduled for local
printers, which can also be canceled from that window.
Since the Series 2800 has two native serial ports, the IP ports 5962 and 6462 have been
added to the seriald daemon for the second native serial port.

on the command line for the base code server and authentication server installations can
now be specified on the graphical interface and a new custom install is available to
the advanced user who wants to be able to control the components individually.
The panels shown here are the panels presented to the user when selecting Custom
Install.
The first allows to eliminate the support for either the Power PC based Network Stations or
the X86 based Network Stations in the case where the server being installed is only
required to support one of these two families.
The second panel lists the components that can be selectively chosen for inclusion or
exclusion during a Custom install. This capability allows the administrator a much finer
control over the components that are required and therefore the space needed to install
the product. For example, if Emulation and ICA are never used, those components can be
completely removed from the installed code.
The last panel deals with the Network Station manager program itself (which is not
required on a base code server for example) and the Network Station Login service which
is only required on an authentication server.

Notes
For those who were very knowledgeable in the V1R3 release, the biggest difference lies in
the way to interface with the station's functions and the way to get at the information
required to do problem determination.
Since the Network Station console has been replaced with a command line interface, this
diagram summarizes the differences between the functions provided through the V1R3
Console facilities and the way to get similar functions through the V2R1 command line.
At the top is the V1R3 console with each pulldown expanded to show the available
functions. The functions that are either not applicable or not available in V2R1 have been
indicated with a horizontal bar through it.
Others have an arrow pointing to the command to issue on the V2R1 command line to get
either an identical or similar function.
In the case of the Screen lock and the Logout, it is not a command but a click on an icon
located at the bottom of the launchbar, and the memory function is located at the top of the
launchbar (if enabled).
In general, there is additional flexibility provided in V2R1 through a variety of commands
that were not available in V1R3 but it takes a bit of time to get used to the new
environment, as with any change.

Notes
This is another way to look at some of these differences. We have tried to include as many
of these as we could, so far anyway, in the redbook in order to guide V1R3 users through
the transition.
This table shows some of the common functions, how it was done in V1R3 and how it is
accessed in V2R1. It is not meant to be complete but only as an example of some of the
common functions.
Since V1R3 did not really have a command line facility, as V2R1 does, most functions can
now be performed through some command on the command line.
This is very handy for the administrator but the end user will most likely perform all of its
functions through the graphical interface of the icons on the launchbar. The command line
is a diagnostic facility more than an operational facility.

Notes
From a base function perspective, the V1R3 and V2R1 boot monitors are similar since
they carry out the same functions. However, there are quite a lot of differences in many
aspects. For example:
The menus are more extensive and easier to use in V2R1
The Service aids functions are selectable in a menu and there are a lot more service LAN
trace functions provided
There is a better protection against update failures
The V2R1 boot monitor supports the newer level of DDC type monitors
Dump files are now uploaded by the kernel
The boot code has DNS capability during the boot phase
The boot monitor removes itself from memory after the kernel is operational
The DHCP client in the boot monitor now accepts only valid responses from a DHCP
server (meaning that if options 66 and 67 are not present in the offer for example, the offer
is rejected).
There is no command prompt

Notes
The least apparent changes are probably in the new kernel, since this is underlying
support that the user is not really exposed to.
For those with an interest at that level of details, here is a list of some of the
enhancements provided by the new kernel.
The most significant of these is probably the added stability and robustness that it
provides.
