IIS blocking LFTP command <p>I'm trying to execute a LFTP command using the <code>system()</code> PHP method in a IIS 7.0 site.</p> <pre><code>$command = 'cmd /c lftp -c "open -u name,password -p 22 sftp://server.mylife.com ; cd test/portal/template ; put /cygdrive/c/inetpub/uploads/cata/exports/tpl_1421946484/cata.csv;"'; system($command); </code></pre> <p>I put it in a PHP file. If if run it directly by the command line <code>php sendFile.php</code> it works fine. But if I access this same php file throught a IIS 7.0 website, I got nothing and no error.</p> <p>I can't understand where it comes from...!</p> <p>Any help ?</p>
