RE: "Get RDP File" Doesn't work first try if too fast
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 "\n"; print " .off {\n"; print " visibility: hidden;\n"; print " } .on {\n"; print " visibility: visible;\n"; print " }\n"; print "\n"; print "\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 "\n"; print "For automatic connection, you can download an RDP file that can "; print "be opened by the Remote Desktop Connection program.\n"; print ""; print "\n"; print " \n"; print "\n"; print " \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 " \n"; print " \n"; print " \n"; print "\n"; print " \n"; print "\n"; - Gerhard Hartl Old Dominion University Norfolk, VA -Original Message- From: Andy Kurth [mailto:andy_ku...@ncsu.edu] Sent: Monday, April 04, 2011 1:33 PM To: vcl-user@incubator.apache.org Subject: Re: "Get RDP File" Doesn't work first try if too fast I have seen the same issue myself.

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.

"Get RDP File" Doesn't work first try if too fast
(disregard previous, forgot to retitle) Since upgrading to 2.2, when a user browses to the 'connect' page, I've noticed that the clients ip is captured and the management node then ssh's to the vm and opens up the port for the clients ip on 3389. While I understand this is best practice, I have noticed that if they user is to quick clicking through the page that they sometimes have to click the "Get RDP File" twice since the first time tries to connect prior to the port being opened up. Is there any way around this? - Gerhard Hartl Old Dominion University Norfolk, VA
