This is known as a <em>cascaded Telnet session</em>. Using this method, <span>you</span> will be able to:</p>

<ul><li>Establish Telnet sessions between <span>the</span> home office
|

|
|
and Chicago.</li>

Lowe is the director of marketing at Culver Pharmaceuticals. She connects
|
||
|
|
from the office in New York and accesses the main system in Chicago using
|
||
|
|
Telnet. After Janice has established a client session with the Telnet server
|
||
|
|
in Chicago, she realizes that she needs to work with some files from the Los
|
||
|
|
Angeles office. </p>
|

|
|
<div class="section"><h4 class="sectionscenariobar">Objectives</h4><p>Janice
|
||
|
|
uses the Chicago Telnet client to connect to the Los Angeles Telnet server.
|
||
|
|
While connected to Los Angeles, she decides to establish a session with Houston.</p>
|
||
|
|
<br /><img src="rzaiw513.gif" alt="Cascaded Telnet session. Image is described in the text." /><br /><p>This figure depicts the connections <span>that</span> Janice makes. The iSeries™ server <span>that</span> she
|
||
|
|
starts from in New York is called the home system. From there, she connects
|
||
|
|
to intermediate system B in Chicago, then connects to intermediate system
|
||
|
|
C in Los Angeles, which connects to end system D in Houston.</p>

and assumptions</h4><p>This scenario makes the following assumptions:</p>
|

|
|
<ul><li>Telnet server running on all systems.</li>
|
||
|
|
<li>Janice has a sign-on in all systems.</li>
|

<li>All systems are iSeries servers running i5/OS™ or later.</li>

</div>
|

|
|
<div class="section"><h4 class="sectionscenariobar">Configuration details</h4><p>Janice
|
||
|
|
completes the following steps to connect to the Telnet systems:</p>
|
||
|
|
<ol><li>From the New York system, type <samp class="codeph">STRTCPTELN CHICAGO</samp>.</li>
|
||
|
|
<li>On the Chicago system, type <samp class="codeph">STRTCPTELN LA</samp>.</li>
|
||
|
|
<li>On the Los Angeles system, type <samp class="codeph">STRTCPTELN HOUSTON</samp>.</li>
|
||
|
|
</ol>
|
||
|
|
<p>After she has connected to the Houston system, she wants to complete
|
||
|
|
a task on the New York (Home) system.</p>
|
||
|
|
<ol><li>Press the <span class="uicontrol">System Request</span> key.</li>
|
||
|
|
<li>Select option 14 (Transfer to home system). This returns her to the alternate
|
||
|
|
job on the New York system.</li>
|
||
|
|
</ol>
|
||
|
|
<p>After she has completed her work on the New York system, she can return
|
||
|
|
to the Houston system by completing the following tasks:</p>
|
||
|
|
<ol><li>Press the <span class="uicontrol">System Request</span> key.</li>
|
||
|
|
<li>Select option 15 (Transfer to the end system). This takes her from any
|
||
|
|
intermediate or home system to the end system.</li>
|
||
|
|
</ol>
|
||
|
|
<p>To sign off from all sessions, she uses the SIGNOFF command. This
|
||
|
|
ends the current session and returns her to the sign-on display of the home
|
||
|
|
system.</p>
