<h3 id="scenario7">Scenario: Configure a PPP connection from a server that provides connectivity
|
||
|
|
for other systems through an ISP</h3>
|
||
|
|
<p class="sectionscenariobar"><span class="bold">Situation</span></p>
|
||
|
|
<p>Suppose you are responsible for maintaining an iSeries™ server for
|
||
|
|
MyCompany, a small manufacturing company in Boone, Iowa. As part of providing
|
||
|
|
this support, you need to establish a connection between electronic customer
|
||
|
|
support and MyCompany's iSeries server.</p>
|
||
|
|
<p>Since MyCompany has an Internet bound network connection, you can create
|
||
|
|
a connection from your iSeries server through your modem to a dial up point-to-point
|
||
|
|
(PPP) connection. Because your network includes three other iSeries servers,
|
||
|
|
you also want to consider providing connectivity to electronic customer services
|
||
|
|
through the Universal Connection from MyCompany's main server.</p>
|
||
|
|
<p class="sectionscenariobar"><span class="bold">Solution</span></p>
|
||
|
|
<p>Create a Universal Connection to IBM® through the a dialup point-to-point connection
|
||
|
|
over the Internet. In this case, you establish a connection through the Connection
|
||
|
|
Manager on your local iSeries server through a point-to-point Internet connection
|
||
|
|
to electronic customer support. In this case, your main server can act as
|
||
|
|
a connecting point for the other three MyCompany servers in your company that
|
||
|
|
need to connect to electronic customer support services, as described in <a href="scenario8.htm#scenario8">Configure a multi-hop connection through
|
||
|
|
a remote server</a>. As part of your server configuration and setup, the wizard
|
||
|
|
will create an L2TP terminator profile, or you can select an existing L2TP
|
||
|
|
terminator profile. See <a href="../rzaiy/rzaiyvrtline.htm">L2TP (virtual line)</a> for additional
|
||
|
|
information about L2TP terminator profiles. In addition, the wizard will configure
|
||
|
|
the Service and Support proxy.</p>
|
||
|
|
<p class="sectionscenariobar"><span class="bold">Advantages</span></p>
|
||
|
|
<p>This scenario provides the following advantages: </p>
|
||
|
|
<ul>
|
||
|
|
<li>MyCompany does not need to invest in additional hardware
|
||
|
|
or software to receive benefit from electronic customer support. You can configure
|
||
|
|
this connection through the Universal Connection wizard or CL commands.</li>
|
||
|
|
<li>MyCompany's other three servers can remotely connect to electronic customer
|
||
|
|
support through a single server. MyCompany would only need a single modem
|
||
|
|
and dialup ISP connection instead of a separate one for each system or partition.</li></ul>
|
||
|
|
<p class="sectionscenariobar"><span class="bold">Objectives </span></p>
|
||
|
|
<p>In this scenario, the customer wants to ensure that IBM can support
|
||
|
|
the MyCompany system over the network though a point to point connection through
|
||
|
|
MyCompany's Internet service provider (ISP) connection. The objectives of
|
||
|
|
this scenario are as follows: </p>
|
||
|
|
<ul>
|
||
|
|
<li>To create a secure point-to-point dial-up connection between the MyCompany's
|
||
|
|
four servers and electronic customer support through MyCompany's ISP.</li>
|
||
|
|
<li>To automate customer support through electronic customer support and services</li>
|
||
|
|
<li>To allow electronic customer support to create an electronic hardware
|
||
|
|
and software inventory of MyCompany's iSeries system</li>
|
||
|
|
<li>To permit electronic customer support to send software fixes and updates
|
||
|
|
to MyCompany over the network</li></ul>
|
||
|
|
<p class="sectionscenariobar"><span class="bold">Details</span></p>
|
||
|
|
<p>The following diagram illustrates connecting the MyCompany iSeries server to
|
||
|
|
electronic customer support through an point-to-point ISP connection.</p>

|
|
<p><span class="bold">Configuring Universal Connection</span></p>
|
||
|
|
<ul>
|
||
|
|
<li>iSeries Navigator launches the Universal Connection Wizard to configure
|
||
|
|
the connection. This only needs to be done once unless some configuration
|
||
|
|
information needs to be updated.</li></ul>
|
||
|
|
<p><span class="bold">Using Universal Connection</span></p>
|
||
|
|
<p>When a Service Application wants to use the Universal Connection to communicate
|
||
|
|
with IBM the following will occur:</p>
|
||
|
|
<ul>
|
||
|
|
<li>If iSeries A needs to connect and the connection to your ISP
|
||
|
|
is not currently active, the specified profile is started to allow connections
|
||
|
|
to the Internet. If the service application on iSeries B, C, or D is not providing its own
|
||
|
|
security, an L2TP tunnel is established to iSeries A. The ISP connection must be active.
|
||
|
|
If the service application can use a proxy, a HTTP or HTTPS connection is
|
||
|
|
made through the Service and Support proxy.</li>
|
||
|
|
<li>A Virtual Private Network (VPN) is established through your
|
||
|
|
existing Internet connection to a VPN Gateway at IBM if the service application is not providing
|
||
|
|
its own security.</li>
|
||
|
|
<li>The service application communicates with the appropriate IBM servers to perform
|
||
|
|
the requested service.</li></ul>

<p id="scenprereqs7" class="sectionscenariobar"><span class="bold">Prerequisites
|
||
|
|
and assumptions</span></p>
|
||
|
|
<p>The prerequisites for enabling electronic customer support over a point-to-point
|
||
|
|
ISP connection include:</p>
|
||
|
|
<div>
|
||
|
|
<ul>
|
||
|
|
<li>Ensure that the iSeries Access for Windows® and iSeries Navigator exist on your personal computer,
|
||
|
|
as described in the <a href="../rzaij/rzaijrzaijinstall.htm">iSeries Access for Windows:
|
||
|
|
Installation and setup</a> topic.</li>
|
||
|
|
<li>Ensure that you install all of the latest service packs for iSeries Navigator.
|
||
|
|
The scenarios show using the V5R4 version of the software.</li>
|
||
|
|
<li>Ensure that TCP/IP is active. You can start TCP/IP through the Start TCP/IP
|
||
|
|
(STRTCP) command.</li>
|
||
|
|
<li>You must have security officer (*SECOFR) authority with *ALLOBJ,
|
||
|
|
*IOSYSCFG, and *SECADM special authorities in your i5/OS™ user profile and *USE authority to WRKCNTINF
|
||
|
|
in order to configure the connection using the Universal Connection wizard.</li>
|
||
|
|
<li>You must install the TCP/IP Connectivity Utilities (5722–TC1).</li>
|
||
|
|
<li>For the virtual private network (VPN) and SSL to operate,
|
||
|
|
you must install the Digital Certificate Manager (DCM) (5722-SS1 option 34).</li>
|
||
|
|
<li>Ensure that the QRETSVRSEC system value is set to 1. You can
|
||
|
|
check this value with the Display System Value (DSPSYSVAL) command. If this
|
||
|
|
value is not set to 1, enter a Change System Value (CHGSYSVAL) command. This
|
||
|
|
allows the account userid and password to be stored on the iSeries server.</li>
|
||
|
|
<li>If you are using an internal modem such as the 56 Kbps modem
|
||
|
|
that is provided with the 9793 adapter card, ensure that the network attribute
|
||
|
|
MDMCNTRYID is set appropriately. You can check this value with the Display
|
||
|
|
Network Attributes (DSPNETA) command. If this value is not set correctly,
|
||
|
|
change this value with a Change Network Attributes (CHGNETA) command.</li></ul></div>
|
||
|
|
<ul>
|
||
|
|
<li>If connecting for others servers, ensure that the connection to the ISP
|

is active before connecting to electronic customer support.</li></ul>
