• Apache 2.0.55/PHP 5.3.5 Hangs

  - by Rushyo

  Recently inherited a Windows 2k3 server running XAMPP, including ancient copies of PHP, MySQL and Apache. I'm attempting to install a second, up-to-date PHP installation on the machine so I can reference that in future instead of XAMPP's old one. Apache starts up with this new PHP installation happily. Unfortunately, when Apache references the new PHP install, whenever I try a view a page (even a non-PHP page) it hangs. The server simply doesn't respond to any HTTP request - it doesn't crash either. It just sits there with the connection open. There are no errors/warnings/notices in either the PHP or Apache logs. I've pretty much ruled out PHP's extensions (by process of systematic elimination) and most of the INI settings. I've tried reinstalling PHP from scratch. The PHP installation is PHP 5.3.5 x86 thread-safe compiled w/ VC6. The Apache installation is Apache 2.0.55. Anyone encountered similar behaviour?

• Adobe Plugin in Firefox showing grey screen; something to do with range requests on Apache?

  - by Sam Minnée

  I have a web page with a link to a PDF file (target="_blank"). If I click the link, the PDF reader just shows a grey screen within the Firefox browser. If I copy that link and manually open it in a new tab, the PDF will display correctly, and subsequent requests made by clicking the original link now work, suggesting that the problem occurs when loading the file into the cache. It appears as though the Adobe PDF reader plugin is making byte-range requests (I see lots of 206 responses) and I suspect that this may be the cause of the issue. I am running an Apache webserver. Has anyone had problems with Apache and Adobe's byte-range requests? Are there any workarounds?

• USB Audio device not selectable in settings after Camtasia Studio

  - by DJDavid98

  I tried to use Camtasia Studio 7 Recorder today, and when I selected the "Record Microphone and System audio" option, the recorder crashed, and then my sound settings icon disappeared. If I tried to open the Camtasia Recorder's Options or tried to select the option again, the program crashed. After holding the power button to force restart (so My settings wouldn't save, theoretically) the audio device was still not showing up in the sound settings, although it still is displayed under the "Hardware" tab, and is Functional. Or at least that's what windows thinks. I tried uninstalling Camtasia, and no sucess either. The USB audio device is labeled "C-Media USB Headphone Set". OS: Windows XP SP3 hu-HU Is there any way I could make it work again, like registry editing or something?

• Webpage redirection time

  - by Abhijeet Ashok Muneshwar

  I want to calculate time consumed in redirecting from 1 webpage to another webpage. For Example: 1) I am using Facebook in Google Chrome browser. I have shared 1 link on my Facebook profile like below: http://www.webdeveloper.com/ (It's not only Facebook. It can be any domain having link to another domain). 2) When I click on this link from my Facebook profile, then this website will open in new tab. 3) I want to calculate time difference in miliseconds or microseconds between below two events: First Event: Time of clicking link "http://www.webdeveloper.com/" from my Facebook profile. Second Event: Time of completely loading webpage of "http://www.webdeveloper.com/". Thank you in advance.

• How can I create an external SSL wrapper/tunnel page for an insecure webpage behind a firewall?

  - by Ross Rogers

  I have an security cam with a built-in webpage inside my home network. That camera is using basic HTTP authentication instead of SSL. I want to be able to access the camera's webpage from outside my network, but I don't want to open an unencrypted video stream to the outside world. Right now, I'm doing some cumbersome ssh tunneling where I bounce off an ssh server like: ssh -N -L 9090:CAMERA_IP:80 [email protected] and then I connect to my web page like: http://localhost:9090 But this is a pain. Now, gentle reader, I beseech you to tell me how I can use linux (Ubuntu) to get a fully encrypted SSL connection to my internal web page without the hassle of creating an ssh tunnel each time. I believe I can use stunnel, but I'm not sure of the command.

• How to execute everything in the Local Area Network

  - by matnagel

  We have a very small LAN here, but some peolpe here think we need Active Directory, though nobody knows how to maintain it. I am not in the position to change this. How can I get full access (on Linux it would be "execute" rights) also for files on network drives (the files are just on another machine next room) My account is in the group Administrators on a windows 2003 server Domain Controller. I cannot open simple MS Access 2000 Databases or CHM Files from network drives in the lan How to do that? Some policy setting? I want to change that once. It is useless. We have no distinction between local or network files here. I would have to copy everything to a local drive and then do what I want.

• Understanding an Application based on the OS interaction with a Hypervisor

  - by Dewy

  Following I will ask a few specific questions but I will set the stage first. My goal is to monitor Applications in a very odd place - between the OS and a Hypervisor. If you have comments about this probably unachievable goal please do educate me. One good advice or link can save me days of work. Now to my current attempt. I installed on WinXP a VirtualBox (being open-source) and got a guest OS of latest Ubuntu running within. Where should I go next? Can I set the logs to show all memory/CPU/disk instructions of the guest OS? Thanks, Dewy

• External USB Fingerprint Reader for Pre-boot Authentication for Dell Laptop

  - by cop1152

  My company just purchased several Dell Latitude E6500 laptops with docking stations and external monitors. These laptops have a fingerprint scanner located next to the keyboard. DOCKED users who prefer to use the included fingerprint scanner for pre-boot authentication are forced to open their laptop in order to access the scanner. This is an inconvenience when the laptop is docked. We are looking for an external, usb fingerprint scanner, that will work with the current preboot authentication setup. I assume that this scanner would have to access the existing credentials for authentication....wherever they are stored. So we would require something that would work PRE-BOOT, use the existing credentials, and not interfere with usage when the machine was not docked, such as when the laptop is being used at home. Does anyone have experience with this scenario? Thanks.

• force other screen on boot

  - by PaoloFCantoni

  I have a multi-boot Windows 7 (32bit & 64 bit) on my HP Notebook. Unfortunately, the Notebook screen has been trashed (due to daughter dropping it). So I have attached a second screen. On the 64 bit system, after windows has started, the logon screen comes up on the 2nd monitor just fine. On the 32 bit system, the logon screen still comes up on the Notebook monitor and I have to open the lid, and shut it so that it then switches to the attached screen. In both cases the display has been set to only display on the attached screen (ie if I "identify" the attached screen says: '1'). Is there any setting I can use to force the OS to use the attached screen? TIA, Paolo

• Aperture and networked drive: thinks images are offline

  - by AK

  I keep my photos on a networked drive (wireless), and they are referenced by Aperture. Aperture seems to not try very hard to look for this drive. Usually I have to open the network drive in Finder before opening Aperture -- otherwise it doesn't find the images and considers them offline. To me this seems like Aperture isn't willing to look on the network for the drive, unless it was helped along by pointing it out in Finder. It doesn't work if I start Aperture first and then navigate to the drive in Finder. What are some workarounds to making this functional? Is there a way to tell Aperture to look again without restarting the program?

• Httpd restart "Address already in use" error

  - by mtndesign

  I have an .rpm, which I created. In its %post part, I do some stuff, and in the end of this script, i call service httpd restart. It gives the following error: + service httpd restart Stopping httpd: [FAILED] Starting httpd: (98)Address already in use: make_sock: could not bind to address [::]:81 (98)Address already in use: make_sock: could not bind to address 0.0.0.0:81 no listening sockets available, shutting down Unable to open logs [FAILED] I got this from the rpm verbose installing (-vv). So I know its about httpd restart itself, nothing else. The according to netstat only one process (httpd) is listening on port 81. $ sudo netstat -nlp | grep 81 tcp 0 0 :::81 :::* LISTEN 29670/httpd I don't understand, why running http FAILS at stop, and FAILS again in start. Any ideas how to solve this?

• Import LDIF file to external server

  - by colemanm

  As a follow-up to my previous question, which I've resolved part of, what we're trying to do now is take an exported .ldif file of the "Users" container on our OS X Server and import it into a separate OpenLDAP server on an EC2 instance. This we'll use for LDAP user authentication of other apps without having to open our internal network to LDAP traffic. The exported .ldif file thinks the DN of the "Users" container is cn=users,dc=server,dc=domain,dc=com. Is it easiest to configure the EC2 OpenLDAP server to think that it's domain is the same so the container is imported to the proper place? Or should we edit the text of the .ldif file to change the DN to match the external naming? Hopefully that makes sense... but I'm confused as to the best way to accomplish this.

• Howto print from dumb terminals with local print server and remote hosted RDP

  - by Matt

  We have essentially a remote office with about 5 dumb terminals. The terminals are connecting to our office directly over a wireless link. What I want to do is connect all their printers onto a print server. But since the remote office is not actually allowed to see our LAN (since they are actually another company) we don't want a full on open VPN tunnel set up. Naturally the RDP traffic passes through a firewall. Is there an easy way to set up the RDP server so that it can see a print server on a remote LAN?

• PHP+AJAX with MySQL - Query every 2 seconds, too many in TIME_WAIT

  - by Ryan

  I have a basic HTML file, using jQuery's ajax, that is connecting to my polling.php script every 2 seconds. The polling.php simply connections to mysql, checks for ID's newer than my hidden, stored current ID, and then echo's if there is anything new. Since the javascript is connecting every 2 seconds, I am getting thousands of connections in TIME_WAIT, just for my client. This is because my script is re-connecting to MySQL over and over again. I have tried mysql_pconnect but it didn't help any. Is there any way I can get PHP to open 1 connection, and continue to query using it? Instead of reconnecting every single time and making all these TIME_WAIT connections. Unsure what to do here to make this work properly.

• Automatic Remote REGEDIT?

  - by SUPER MARIO BROTHERS

  I've got a lot of computers on the domain here that do not have remote desktop enabled. I can open the command prompt and do this command: REG.exe ADD \\[the machine im doing this to]\HKLM\SYSTEM\CurrentControlSet\ Control\\"Terminal Server" /v fDenyTSConnections /t REG_DWORD /d 0 and it works perfectly fine, except for one thing - it makes a prompt asking if I'm sure I want to do this, Yes/No. How would I go about having a batch file auto-answer YES to this, so I don't have to type it every time? It wouldn't be a problem if it was just a couple hundred machines, but there's plenty more than that and it would take a while to do this by hand. Not to mention I might have to sweep a few times to make sure every computer is turned on and is affected by this.

• What would cause Google Music Manager to report different amounts of music between iTunes and My Music?

  - by Thomas Owens

  If I set Google Music Manager to scan iTunes, it reports that there are 3997 songs (which is also indicated if I were to open iTunes and look at my collection). However, if set Google Music Manager to scan My Music folder, it detects 3999 songs. I even deleted all of my songs from iTunes and reimported my My Music folder. iTunes is still reporting 3997 songs. Is there an easy way to find out what is causing the difference between the two counts? I could probably add all of my songs to a playlist, export the playlist into a text or XML file using iTunes, and compare that list against everything in My Music folder to see if iTunes is missing music. However, I was wondering if anyone could shed some light on this before I did that...

• Links not opening in Windows 8 applications

  - by Martin Brown

  I have just upgraded my laptop from Windows 7 Ultimate with IE9 to Windows 8 with IE 10. When ever I try to open a web link in an application nothing happens. For example in the Windows 8 mail application it makes the email address in an email look like a link. When I click on these with the mouse the link changes to look like I have clicked on it, but aside from that nothing happens. I have tried making sure that IE 10 is my default web browser and been into IE10's settings and associated it with all the usual file types, but still no success. Has anyone got any ideas what might be causing this? I have a feeling this started when the Browser Choice update ran. I couldn't select which browser to install in that either. The install buttons just flashed when I clicked them and then nothing. PS I would have added an IE10 tag to this post, but apparently I don't have the reputation required to do so.

• Compiz command plugin won't register keyboard shortcuts

  - by David Moles

  Per this discussion I've enabled the Compiz commands plugin in order to try to bind some keyboard shortcuts to wmctrl actions. CCSM captures my keystrokes just fine, but no matter what keystroke I try or what command I bind it to (everything from my original intention of binding Super-1, Super-2 etc. to wmctrl -o 0,0, wmctrl -o 2560,0, etc., to binding Ctrl-Alt-Shift-L to gnome-terminal). Basic compiz shortcuts for window switching and so on -- even custom ones -- seem to work fine, but the command plugin doesn't seem to be working at all. I also notice the following symptom: when I open the keyboard shortcut tab in CCSM, the keyboard shortcuts often at first appear blank, though if you click on the blank button, the correct value is still there. Also possibly related, I've noticed that gnome-terminal doesn't seem to notice the Super key, though other apps (e.g. CCSM, Emacs) register it fine. Anyway, it seems like something's eating my keystrokes. Any ideas?

• How to play an MKV 3D side-by-side video?

  - by djechelon

  I have a video in Matroska format (MKV, file extension .mkv), 3D half-SBS, where the 1280x720 frame shows the left-eye frame on the left and the right-eye frame on the right. I don't have a 3DTV, but I have NVidia 3D Vision: I tried to open it with PowerDVD 10 with no result (program hangs). With the same PowerDVD, I tried to play the Avatar 3D trailer downloaded from YouTube (MP4 format), but it now shows it the two frames. PowerDVD 10 is advertised to support 3D and 3D Vision. Why can't I play these videos? NVidia Stereoscopic player plays the Avatar trailer fine, but it doesn't support MKV.

• Office for Mac 2008 suspicious behaviour

  - by Chinmay Kanchi

  Office for Mac 2008 just asked me whether I wanted to update. However, on continuing with the update, a Window popped up saying that I needed to close Chrome before the update could continue. I find this rather suspicious, since Office should not need to go anywhere near Chrome. Any idea why there might be a legitimate reason for this, or alternatively, just what is Microsoft trying to sneak on to my computer? EDIT: I did look at the download details on Microsoft's website, but aside from the general guff about closing all open applications, it doesn't mention anything about Chrome or any browser plugins.

• TightVNC (or any VNC) viewer windows scaling

  - by mr.b

  Hi, I am currently using TightVNC to connect to multiple remote hosts in LAN. I start 16 VNC viewers, set Scaling by: Auto (in connection options display), and then select all viewer windows and use Tile Horizontally, which covers my entire screen with VNC viewers. It all works sort of nice, except that desktop interaction is really slow when there are more then 4 VNC viewers. My question is, does VNC client (not just TightVNC, but any compatible client) support some kind of smart scaling option, so that client tells server something along the lines of: "Okay, I'm displaying your entire screen in a window size 300x225 px, so can you please start sending encoded images on that resolution?", at which point interactiveness of open connections dramatically increase, and when I decide to go full screen on some connection, client and server re-negotiate and server starts sending full resolution images again? Thanks!!

• Edit Enterprise Calendar in Project Server 2010

  - by Chris W

  Has anyone been able to successfully edit the Standard calendar in 2010? I'm trying to change the working times as none of our admin accounts seem able to do it. We're running Project Server 2010 RTM on SharePoint 2010 RTM with Project Pro 2010. When I click the Edit Calendar button in PWA it triggers Project client to open up but it just opens up an empty project and I've not access to edit the Standard calendar using any of the published steps. It would be great to hear if someone has managed to do this so I can work out if it's a general glitch in this build or is it just a problem with out setup.

  Hi I hope someone can help me... I accidentally renamed my own user name on my mac running OS X 10.4.11 and tried renaming back to what it was but now I have two accounts (the one I want to use which has all my preferences, applications, mail boxes, etc etc) is it possible to copy my settings from my original into this new user name?
