|

<dt class="dlterm">Environment options</dt>
|
||
|
|
<dd>INPUT; CHAR(*) An array containing all the RFC 2877 environment options
|
||
|
|
negotiated by the client. These will be in the exact format that they were
|
||
|
|
in when received from the client and specified by RFC 2877. The array will,
|
||
|
|
in general, consist of 1 or more pairs of environment variable names and associated
|
||
|
|
values. The RFC specifies that each variable name will always be preceded
|
||
|
|
by either an X'01' or X'03' depending on whether it is an RFC 2877 defined
|
||
|
|
VAR, or an application specific defined USERVAR. If a value is to be associated
|
||
|
|
with a VAR (or USERVAR), that value will appear next in the array preceded
|
||
|
|
by the RFC 1572 defined VALUE character - X'01'. This sequence of VAR/VALUE
|
||
|
|
pairs will be repeated up to a maximum of 1024 total bytes of negotiation
|
||
|
|
data.<p>RFC 2877 and the more general Telnet negotiation RFCs also allow for
|
||
|
|
control characters to appear within the VAR/USERVAR variable names or their
|
||
|
|
associated values. This is allowed through the use of the ESC character X'02'
|
||
|
|
and rules that apply when the ESC character itself or Telnet IAC control characters
|
||
|
|
must appear in the negotiation sequence. Refer to RFC 1572 for a more complete
|
||
|
|
description of control character escaping rules.</p>
|
||
|
|
<p>While the environment
|
||
|
|
options buffer will show negotiations by the client, including passwords,
|
||
|
|
Telnet will always overlay any clear-text or encrypted password values in
|
||
|
|
the buffer to avoid security exposures.</p>
|

</dd>

|
|
<dt class="dlterm">Length of environment options</dt>
|
||
|
|
<dd>The length of the environment options referenced in the preceding paragraph
|
||
|
|
is typically 1024 bytes. Because option negotiations are of undefined length,
|
||
|
|
any negotiations that exceed the length specified might be truncated
|
||
|
|
to fit in the environment options buffer.</dd>

<dt class="dlterm">Allow connection</dt>
|

<dd> OUTPUT; CHAR(1) Applies to all devices and indicates to the Telnet server
|
||
|
|
whether it should allow the client to connect. If the device type is DISPLAY
|
||
|
|
and you have enabled auto-signon, then this client may also bypass the sign-on
|
||
|
|
panel on the iSeries™ server.
|
||
|
|
The valid values are as follows:<ul class="simple"><li><span class="uicontrol">0</span> - Reject the request from the client</li>
|

<li><span class="uicontrol">1</span> - Accept the request from the client</li>

<dd>OUTPUT; CHAR(1) Applies to DISPLAY device types, and indicates to the
|

|
|
Telnet server whether the auto-signon operation should be allowed to proceed
|
||
|
|
for this particular client. If auto-signon is allowed, then this client can
|
||
|
|
bypass the sign-on panel on the iSeries server. The valid values are
|
||
|
|
as follows:<ul class="simple"><li><span class="uicontrol">0</span> - Reject the application request from the client.

The system will ignore the User profile, Current<sup>®</sup> library, Program to call, Initial

menu, and Device name output parameters.</li>
|

|
|
<li><span class="uicontrol">1</span> - Accept the application request from the client.
|

The system may consider the User profile, Current library, Program to call, Initial

menu, and Device Name output parameters valid if the exit program returns

them.</li>
