<H3>Netstation Clients</H3>
|
|
|
|
<P>
|
|
<P>An NC, connected to your local Network, most likely by a UTP connection , thus
|
|
via a cross-cable or HUB connecting to an Server - in this case a Linux Box
|
|
Basically the NC is Made to work with either AS/400 , Windows
|
|
NT or AIX Servers. These are all expensive solutions, however working
|
|
with thin clients doesnt have to cost that much. (Token Ring versions are
|
|
also available)
|
|
<P>The model I have at my disposal is an IBM Network Station model 8361-100,
|
|
On the inside you can find an 403PPC chip, some S3 vga components, an
|
|
PCMCIA slot, and normal 72 pin (parity ??) simms.
|
|
I found 8+32 Mb in my edition.
|
|
<P>Actually those 40Mb were major overkill. In
|
|
full operation modes with lot's of configuration
|
|
panels a couple of telnet sessions and a X -query open only took up
|
|
about 4Mb of ram. ) So taking out the 32Mb showed absolutely no
|
|
significant loss of speed.
|
|
<P>
|
|
<P>Well, after working more with the Netstation, specially with Navio I found
|
|
out Navio uses as much 27-30 Mb. So those 40 Mb`s really aren`t that
|
|
much hoverkill
|
|
<P>
|
|
<P>
|
|
<P>We proved it was no problem setting it up on a
|
|
Linux only network. You'll need a server that can provide you both with
|
|
about 25Mb of free diskspace for the software, and the capacities to run
|
|
an X -query. In the setup overhere we used a 486DX50 with 8Mb as a
|
|
fileserver and I switch between another 486DX266 (PS/2 85) with 32Mb,
|
|
and my Multia with 48Mb as the X server
|
|
Of course, the faster machines the better.
|
|
<P>
|
|
<H3>Changes in the new versions.</H3>
|
|
|
|
<P>
|
|
<P>The new version comes with a new kernel and some changes in the
|
|
applications.
|
|
The kernel can now be downloaded as a compressed file which speeds up the
|
|
process.
|
|
<P>Starting with the Network Station 3.0, you need a new Boot Monitor or boot
|
|
PROM
|
|
(aka Firmware) with the version 3.0.x or later. Your NetworkStation won't
|
|
work
|
|
with a older boot PROM (aka Firmware) and the new Network Station 3.x
|
|
kernel.
|
|
If you buy a new NetworkStation, you always get one of the latest PROMs Older
|
|
versions can be automatically updated from a boot server, from which the
|
|
new boot PROM get's downloaded. (Could somebody please confirm me that these devices are the 110 versions
|
|
with a PPC 403GC(X) in it !!!!)
|
|
<P>
|
|
<P>There also is a new layout of the Setup Utility where you define you basic
|
|
network settings of your Network Station.

|
<H3>Netvista Clients</H3>
|
|
|
|
<P>The Netvista Clients (2200 and 2800) have been designed to run Linux
|
|
natively, those thin clients are not based on PowerPC Chips but on an
|
|
Intel Chipset therefore running linux on those devices is quite
|
|
straightforward

|
<P>NC kernel, fonts etc.
|
|
<P>In order to boot the NC you will need its Kernel and fonts.
|
|
About 25Mb of files are needed on the server.
|
|
They can be found on an AIX 4.X with the Netstation modules installed.
|
|
Or from the

<H3>NFS Server.</H3>
|
|
|
|
<P>A working NFS server, like in every default Linux distribution.
|
|
Approx 85Mb of diskspace has to be exported to the NC. (this includes a
|
|
lot of documentation which you don't acutally need)
|
|
<P>
|
|
<P>
|
|
<H3>X Server.</H3>
|
|
|
|
<P>Any machine running XDM with enough memory, processor power will do.
|
|
You don't need to have X configured on the machine itselve, it can
|
|
be a head-less server. Basic X Windows install will provide
|
|
you with the necessary deamons.
|
|
<P>
|
|
<P>
|
|
There is the possibility to run a local X11 server which may avoid some
|
|
network traffic. The new version supports a standard X11 and a Motif
|
|
X11 server. Using a configurable menu or by allowing telnet sessions
|
|
you may access other computers/servers on the network.
|
|
<P>You may also be able to export applications to your Netstation
|
|
display withouth actually using XDM . You might want to run an extra window manager.
|
|
This can be done by telnetting into the remote box and typing export DISPLAY=nc_ipnr:0
|
|
and afterwards running the application you want to use.

<H3>DHCP Server</H3>
|
|
|
|
<P>If you have multiple NC's, you may wish to distribute the IP Adresses
|
|
by using a DHCP Server
|
|
how to obtain and configure a DHCP server can be read in the
