For anyone that has this issue, I came up with a temporary solution that is
easy to implement. This will show a count down of 5 seconds then show the Get
RDP File button. This allows enough time for the VCL client to be configured.
Tested with IE and Firefox. Use at own risk!
Roughly around line 2217 (v2.2.1) on requests.php replace the Get RDP File form
section with:
print "<style type=\"text/css\">\n";
print " .off {\n";
print " visibility: hidden;\n";
print " } .on {\n";
print " visibility: visible;\n";
print " }\n";
print "</style>\n";
print "<script type=\"text/javascript\">\n";
print " window.onload = function() {\n";
print " var timeInterval = 5;\n";
print " if (typeof timeInterval === 'undefined' || parseInt(timeInterval) <= 0)
{\n";
print " timeInterval = 1\n";
print " }\n";
print "document.getElementById('counter').innerHTML = \" Ready to connect in \"
+ timeInterval + \" seconds\";\n";
print "var si = setInterval(function() {\n";
print "if (timeInterval === 0) {\n";
print " clearInterval(si);\n";
print " } else {\n";
print "--timeInterval;\n";
print "if (timeInterval !== 0) {\n";
print " document.getElementById('counter').innerHTML = \" Ready to
connect in \" + timeInterval + \" seconds\";\n";
print "} else {\n";
print " document.getElementById('counter').className = 'off'; //Hiding
the counter area.\n";
print " document.getElementById('submit').className = 'on'; //Unhide
the Submit button\n";
print "}\n";
print "}\n";
print "}, 1000);\n";
print "setTimeout(function() {\n";
print "}, timeInterval * 1000);\n";
print "}\n";
print "</script>\n";
print "For automatic connection, you can download an RDP file that can ";
print "be opened by the Remote Desktop Connection program.<br><br>\n";
print "<b id=counter></b>";
print "<table summary=\"\">\n";
print " <TR>\n";
print " <TD>\n";
print " <FORM action=\"" . BASEURL . SCRIPT . "\" method=post
id=\"connect\">\n";
$cdata = array('requestid' => $requestid,
'resid' => $requestData['reservations'][0]['reservationid']);
$expire = datetimeToUnix($requestData['end']) -
datetimeToUnix($requestData['start']) + 1800; # reservation time plus
30 min
$cont = addContinuationsEntry('sendRDPfile', $cdata, $expire);
print " <INPUT type=hidden name=continuation value=\"$cont\">\n";
print " <INPUT type=submit value=\"Get RDP File\" class=\"off\"
id=\"submit\">\n";
print " </FORM>\n";
print " </TD>\n";
print " </TR>\n";
print "</table>\n";

Subject: Re: "Get RDP File" Doesn't work first try if too fast
I have seen the same issue myself. It's a timing issue related to the
'reserved' state. During this state, the vcld process loops until it detects a
value in reservation.remoteIP which gets set when the user clicks 'Connect'.
There is a 5 second wait in between attempts. This could be reduced but the
downside would be a little more processing on the management node.
Once it detects the remote IP has been set, it can take 3-9 seconds for the
firewall-opening commands to be executed.
Quickly looking at the code, I think some improvements can be made to reduce
the lag time. I created an issue for this:
