Replicating a Remote Boot Server Environment

8. In this case, since DHCP is being used, ensure that the DHCP server
options are set up correctly on AS1 server so that the IBM Network
Stations in St. Louis have AS2 server as their base code server. For
example, option 66 would point to different TFTP servers to allow IBM
Network Stations in different locations to get their base code from the
appropriate server. For more details on DHCP configuration, refer to the
manual,
IBM Network Station Manager Installation and Use, SC41-0664
and
TCP/IP Configuration and Reference , SC41-5420, available online at
www.ibm.com/nc/pubs, and www.as400service.ibm.com respectively. In
addition, the
AS/400 TCP/IP Autoconfiguration: DNS and DHCP ,

Refer to the manual
IBM Network Station Manager Installation and Use,
SC41-0664, for performance tuning information. It is available online at the

After completing the steps, the IBM Network Stations at the remote site were
powered on or re-booted. They were able to obtain their base code from their
local AS2 AS/400 server and authenticate against the central AS1 AS/400
server.
7.2 Decentralized Authentication Server
In this example, the central site in Chicago has an AS/400 system (SYSAS1),
a S/390 system (SYS390), and a development AS/400 system (SYSAS3)
installed. In addition, sixty remote AS/400 systems are installed across a
TCP/IP based wide area network. The central AS/400 system (SYSAS1) in
Chicago has V4R3 and Release 3 of IBM Network Station Manager for
AS/400 already installed because they recently completed an IBM Network
Station pilot project. Because the IBM Network Station pilot was successful.
An implementation of IBM Network Stations at the various remote sites was
also planned. The planned network is shown in Figure 126 on page 218.
Although, the normal installation process using either the shipped 5648-C05
CDs or the downloaded code from the Internet and group PTF SF99082 can
be used (as documented in the manual
IBM Network Station Manager
Installation and Use,
SC41-0664), the company decided that a replication
technique would be used instead. We choose the development AS/400
system (SYSAS3) to be the
master remote server cop y for replicating the
master IBM Network Station Manager environment to the remote servers.
Because the remote sites are primarily autonomous and do not want to rely
on the connection to the central site to obtain user preferences, decentralized
authentication was selected. However, for ease of installation, the decision
