    <p>I am using the following script file (ftp_test_2.ps1) to transfer files to an ftp server:</p> <pre><code>#we specify the directory where all files that we want to upload are contained $Dir="C:/Users/you-who/Documents/textfiles/" #ftp server $ftp = "ftp://192.168.100.101:21/" $user = "aP_RDB" $pass = "pw" $webclient = New-Object System.Net.WebClient $webclient.Credentials = New-Object System.Net.NetworkCredential($user,$pass) #list every txt file foreach($item in (dir $Dir "*.txt")) { "creating URI..." $uri = New-Object System.Uri($ftp+$item.Name) $uri "attempting upload... $item" $webclient.UploadFile($uri, $item.FullName) } </code></pre> <p>This works fine when the $ftp is set to the local host and also connecting to another ftp test server. However, on the production ftp server, the server rejects the upload with the Powershell error:</p> <pre><code>Exception calling "UploadFile" with "2" argument(s): "The remote server returned an error: 227 Entering Passive Mode (192,168,101,99,228,67)." At C:\Users\you-who\Documents\SandBox\ftp_test_2.ps1:17 char:24 \+$webclient.UploadFile &lt;&lt;&lt;&lt; ($uri, $item.FullName) \+CategoryInfo : NotSpecified: (:) [], MethodInvocationException \+ FullyQualifiedErrorId : DotNetMethodExceptionPP </code></pre> <p>On the production server there is a FileZilla server running. The messages in the server UI do not "seem" to show any errors:</p> <pre><code>(000029)2/5/2013 5:58:53 AM - (not logged in) (192.168.100.101)&gt; USER aP_RDB (000029)2/5/2013 5:58:53 AM - (not logged in) (192.168.100.101)&gt; 331 Password required for ap_rdb (000029)2/5/2013 5:58:53 AM - (not logged in) (192.168.100.101)&gt; PASS ******* (000029)2/5/2013 5:58:53 AM - ap_rdb (192.168.100.101)&gt; 230 Logged on (000029)2/5/2013 5:58:53 AM - ap_rdb (192.168.100.101)&gt; OPTS utf8 on (000029)2/5/2013 5:58:53 AM - ap_rdb (192.168.100.101)&gt; 200 UTF8 mode enabled (000029)2/5/2013 5:58:53 AM - ap_rdb (192.168.100.101)&gt; PWD (000029)2/5/2013 5:58:53 AM - ap_rdb (192.168.100.101)&gt; 257 "/" is current directory.

I searched the web and MS sites for help on this, but could not find anything on . Any help greatly appreciated. </p> <p>-Dave Ef</p>

    2. COYou could take a look at the ftp client powershell module here: http://gallery.technet.microsoft.com/scriptcenter/PowerShell-FTP-Client-db6fe0cb it defaults to active mode when you setup the conncetion, and is easy to use

    3. CO@Goyuix While the answer to this question is contained in the answer to the one you linked, I'd not call this an exact duplicate as this question specifically asks about how to make an FTP connection active as opposed to passive, whereas the other just asks how to upload a file with FTP.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
