<div><div class="section"><h4 class="sectiontitle">FTP client subcommand</h4><p>The SECOpen FTP client subcommand
|
|
opens a secure control connection to an FTP server using the specified security
|
|
option. The syntax of this subcommand is:</p>
|
|
<div class="figborder"><p>SECOpen systemname [portnumber] [security_option ]</p>
|
|
</div>
|
|
<div class="note"><span class="notetitle">Note:</span> SOpen is a synonym for SECOPEN.</div>
|
|
<dl><dt class="dlterm">systemname</dt>
|
|
<dd>Enter the name or Internet address of the remote system.</dd>
|
|
<dt class="dlterm">portnumber</dt>
|
|
<dd>Enter the port number for this connection.</dd>
|
|
</dl>
|
|
<div class="note"><span class="notetitle">Notes:</span> <ul><li>If this parameter is omitted and (SSL is specified, the port number 21
|
|
will be used.</li>
|
|
<li>If this parameter is omitted and (IMPLICIT is specified, then port number
|
|
990 is used.</li>
|
|
<li>If both the port number and the security_option are omitted, then port
|
|
number 21 and (SSL are assumed.</li>

</ul>
|

</div>
|
|
<p><strong>security_option</strong></p>

|
<p>Specify the type of security to

be used.</p>
|
|
<dl><dt class="dlterm">(SSL</dt>
|
|
<dd>Uses a secure SSL connection to the FTP server. The AUTH (Authorization)
|
|
server subcommand is used when making the connection.</dd>
|
|
<dt class="dlterm">(IMPLICIT</dt>
|
|
<dd>Uses an "implicit" SSL or TLS secure connection to the FTP server. An
|
|
"implicit" SSL connection is made without sending the AUTH, PBSZ, and PROT
|
|
sever subcommands to the server. In this case, the server must be configured
|
|
to expect an SSL/TLS connection negotiation to occur for the specified port
|
|
number.<p>For the "implicit" SSL case, the server will act as if the client
|
|
had sent these subcommands with the parameters shown below:</p>
|
|
<ul><li>AUTH SSL</li>
|
|
<li>PBSZ 0</li>
|
|
<li>PROT P</li>
|
|
</ul>

|
</dd>
|
|
</dl>
|
|
<div class="note"><span class="notetitle">Note:</span> If the security_options parameter is not specified, then
|
|
(SSL will be assumed. When the port number used is 990, then (IMPLICIT is
|
|
assumed.</div>
