• Acrobat keyboard stealing in Firefox

  - by Uiy

  There are times when I open a pdf in firefox(which uses the acrobat plugin) and the "pdf" steals control of the keyboard. The arrow keys do not work in other programs. Well, If I hold them down they will then work but it becomes hard to navigate that way. It seems acrobat installs a global keyboard hook in some cases and takes control of the keyboard. This didn't start happening until recently(a few months ago). Note that it doesn't happen on all pdfs and everything returns to normal when the pdf is closed. This seems to be an issue with acrobat... maybe a setting? Anyone have any ideas what is going on?

• Windows Services don't automatically start after reboot?

  - by James Crowley

  We've got some Windows services written in .NET. They start fine manually within the services mmc, but despite being set to Automatic, they never start when powering on (or rebooting) the machine. Update In the event log, instead of seeing "xyz started", alongside all the other services starting, I just see "The xyz service entered the stopped state." and a seperate error that says "A timeout (30000 milliseconds) was reached while waiting for a transaction response from the slsvc service.". If I manually start them, then I get a normal in the event log as expected, and all is fine - until the next Windows Update patch which forces a reboot and all the services are off again. Any ideas? I've tried setting them to Delayed Start with no apparent difference.

• How ssl is usually set up on shared hosting (newbie question)?

  - by spirytus

  I am quite unclear on how ssl is usually set up on shared hosting. I have account with justhost.com and they provided me with public_html folder and (its sibling) ssl folder. When I create ssl certificates via cPanel it appears in SSL folder. Now, where I should put my html files to be accessible via https:// rather than http? normal files go into public_html (I figured this out ;) what about secure bunch? Also how can I specify that secured folder shouldn't be the ssl folder (if its the one in fact) but rather some other folder I specify? Is it possible at all with shared hosting? Thank you all for your help, I googled for hours and still am heavily confused as you see :)

• Moving windows using keyboard...faster?

  - by Alois Mahdal

  I like using keyboard shortcuts because it's faster as it does not force me to move my hands off the keyboard. In Windows I can use them to move windows around desktop: Press Alt+Space to open common windows menu Press M to choose "Move" command Navigate window position by cursor keys Confirm new position with Enter Additionally, to achieve better accuracy, I can hold Ctrl while navigating. Now the problem is that the normal "step" when moving is about 20px, and my desktop is quite large, so "walking" all the way across takes quite a long time. This kind of defeats the purpose of using keyboard for these tasks. Is it possible to change size of this step so that takes less steps to walk the same distance? (I imagine a hidden setting in Windows registry...?) I tried holding Alt while navigating, but it does not seem to have influence on speed.

• Lots of files being used by blank web page. What are they?

  - by byronyasgur

  I am trying to optimise a website and I was using the network waterfall facility in Google Chrome. When I looked at the results there were lots of files which I didnt recognise. I first thought they might be something to do with Google Chrome itself, so I put a blank HTML file on my desktop and checked but there was nothing in the waterfall except the file itself. So I put a blank file on my server and I got the output below. What are all these files, are they all necessary, is this normal and do I need to be in any way concerned. My hosting provider has always been excellent in every regard that I'm aware of. My host is shared hosting, using cpanel and is based on a LAMP server. I also note that a couple of those file have problems but I have no idea how to fault find that or whether it's a concern. EDIT: I have cleared the cache so I don't think it's a browser cache issue.

• Can not access to my apache server remotely

  - by Jichao

  I have bought a VPS server, setted the apache server. But I could only access the webpage from local, I thought maybe the server did not recieveing access from outside. I tried Firefox, but the access_log shows nothing accessed. But telnet http://www.59lt.com 80 and type nonsence code, I recieved following error: and the access_log under /etc/httpd/logs also caught the acess, This proved that the server do access request from outside, so why it ignore the normal request from Firefox, but choosed to recieving request from telnet? Thanks. PS: I'm using CentOS + yum installed apache(just now installed).

• Keyboard layout to shift wasd keys

  - by Joel Coehoorn

  I like to play video games on my computer. One of the things that bugs me, though, is how the wasd keys became the standard movement keys in first person shooters and mmorpgs. To me, esdf makes a lot more sense, because that matches your normal hand placement for typing. "Fixing" that layout is always the first thing I do when installing a new game. Sadly, this is often a pain in the neck, and some games won't let you do it at all. Is there an alternative keyboard layout you can install that will just switch these around, so the wasd keys fall in the esdf positions? And is low-level enough two work with DirectX/DirectInput, perhaps that works with the language bar for easy swapping back and forth?

• Windows 2003 Server Intermittent DNS Issues

  - by Mike

  Looking for a little help here. I have a Windows 2003 DNS Server set up on our network. Lately computers on our LAN have been, at times, unable to resolve a certain sub domain for our website whereas other times the request is resolved just fine. During these periods of "downtime" all other network activity (i.e web sites, internal resolutions, network shares, etc.) remains normal. I can tell it is a problem with our DNS server because the resolution always works from outside our network. I'm hoping someone out there has experienced something similar or could at least offer me place to start troubleshooting. Thanks!

• How to restore default iPod playlists on Amarok?

  - by obvio171

  I wanted to "reset" the collection on my iPod and ended up accidentally deleting, through Amarok, all the playlists, including the default ones like "Most Played" and "Highest Rated". Since these are dynamic playlists with a special meaning for iPod, I don't think creating new, normal playlists with the same name will bring their special behavior back. How do I restore them with the same dynamic functionality? Is there a way to do that on Amarok? Rhythmbox? GTKPod? Command line? P.S.: not entirely sure what the policy about iPod questions are, but this one in particular seems to me to be very computer-related because, although it's about interfacing with a device, everything has to be done on my computer, using standard PC libraries/programs, etc. If it's still off-topic, please point me to where I could post it.

• How to check use of userva boot option on Win 2K3 server

  - by Tim Sylvester

  I have some 32-bit Win2K3 servers running an application that fails now and then apparently due to heap fragmentation. (Process virtual bytes grows, private bytes does not) I do not have access to the source code or build process of this application. I have modified the boot.ini file on one of these servers to include /userva=2560, half way between the normal mode of operation and the /3GB option. Normally it takes weeks to reach the point of failure, but I'd like to see right away whether this has actually had any effect. As I understand it, this option limits the kernel to the remaining address space (1536MB instead of 2048), but does not necessarily give an application the extra address space, depending on the flags in the application's PE header. How can I determine whether the O/S is allowing a particular application, running in production, to access address space above 2GB? Additionally, what's the best way to monitor the system to ensure that the kernel is not starved for address space, and more generally how should I go about finding the optimal value for this setting?

• Solaris x86: Non working keys on keyboard (<, >, #, |)

  - by Thomas

  Hello everyone, I have a new installation of Solaris 10 10/09 on x86 hardware. The attached keyboard has a normal German layout. The system is configured accordingly by 'kbd -s'. The generic keys (letter, number, umlaut) work fine. Unfortunately some keys like <, , | or # do not. They produce no output on the text console at all. I tried PS/2 and USB keyboards. I cannot test it under X11 as it is currently not working. Thanks.

• Need a solution to stop students from rotating screen on laptops with intel graphics

  - by testguy

  We have some students who have figured out how to rotate the screen using either the hotkey combination or right click context menu. It's easy to fix but it's time consuming because no matter how many times I tell people how to fix it there's always someone that will come up to me. Now I need two things. First, is there a way to disable screen rotation? Second, I need a script to reset the screen resolution to normal on logon and logoff. The solutions need to be able to be deployed from a Win2003 server to WinXP clients. I have way too many computers to go through by hand to uncheck enable hot keys on the intel control panel.

• How to benchmark kernel (-Os vs -O2)

  - by NightwishFan

  It seems logical to me that on a 64-bit kernel compiling it to optimize for size might help overall. (My distro of choice uses -O2) It has the benefits of more registers and memory and perhaps less cache contention than normal optimized code. I have a kernel compiled like this and it seems excellent. However my question is how can I prove this? I like using Phoronix for "real world" sort of benchmarks so I would prefer to test cases like that. What should I pick to test? Does anyone else have any alternatives? Thank you very much in advance.

• Expression web ftp: Stuck at "Listing subsites"

  - by FrankPython

  When I try to use the Expression Web 4 built-in ftp I see the message ""Listing subsites in.." and soon afterward "passive ftp not available". If I switch to active, I get "active ftp not available". There are no subsites. It is a simple directory with one html page. Backend is a normal IIS6 server. FTP to the same IP with other FTP clients works fine! Any idea if Expression web has some specific requirements? It is our own dedicated server. (Please no tips to use another tool, for this specific project Expression Web is a requirement).

• nginx hashing on GET parameter

  - by Sparsh Gupta

  I have two Varnish servers and I plan to add more varnish servers. I am using a nginx load balancer to divide traffic to these varnish servers. To utilize maximum RAM of each varnish server, I need that same request reaches same varnish server. Same request can be identified by one GET parameter in the request URL say 'a' In a normal code, I would do something like- (if I need to divide all traffic between 2 Varnish servers) if($arg_a % 2 == 0) { proxy_pass varnish1; } if($arg_a % 2 == 1) { proxy_pass varnish2; } This is basically doing a even / odd check on GET parameter a and then deciding which upstream pool to send the request. My question are- What is the nginx equivalent of such a code. I dont know if nginx accepts modulas Is there a better/ efficient hashing function built in with nginx (0.8.54) which I can possibly use. In future I want to add more upstream pools so I need not to change %2 to %3 %4 and so on Any other alternate way to solve this problem

• Migrating to ssh key authentication; implications of adding sbin's to users $PATH

  - by ancillary

  I'm in the process of migrating to key's for authentication on my CentOS boxes. I have it all set up and working, but was a bit taken aback when I noticed service (and other things) didn't work the way I was accustomed to. Even after su'ing to root, still had to call the full path for it to work (which I assume to be expected/normal behavior). I also assume this is because there are different $PATH's for root (what I was using and am used to) and the newly created, key-using user. Specifically, I noticed the sbin's of the world missing from the user path. If I were to add those paths (/sbin/,/usr/sbin/,/usr/local/sbin) to a profile.d .sh script for this new key-loving user, would: I be opening up the system in ways I shouldn't be? I be doing something I needn't do save for reasons of laziness? I create other potential problems? Thanks.

• Subscribe to feed in Thunderbird from the command line?

  - by Coderer

  From reading around the web, it looks like Firefox's "quick view" of an RSS feed sometimes lets you "Subscribe to this feed using" Thunderbird. For whatever reason, that's not an automatically-added option with my setup (FF 3.5.something + Thunderbird 3.0.something on Linux), so I figured I could just "Choose Application...", point at the Thunderbird binary, and be on my way. Not so -- nothing appears to happen. If I run thunderbird from the command line as thunderbird "http://path/to/feed" the app launches as normal. If it's already running, absolutely nothing happens. Is this impossible? Is there some mojo I can pass Firefox to tell it that Thunderbird exists? Should I just suck it up and copy/paste the URLs manually?

• Are these symptoms of a video card is dying?

  - by K Cloud

  What I am getting from my PC: Scrambled text in the boot menu. The scrambled text dissapears and everthing goes normal after several restarts, or the computer has worked for some time. Display goes blank showing, windows kernel mode driver stopped responding. Sometimes the windows just hangs, I need to restart the pc for that. There used to be some scrambled colors in my windows, so I cleaned up my video carda and port and reinstalled the video card, things are something right. The pc runs normally for hours in safe mode, as diffault display driver works at that case. My PC specs: Core 2 Duo processor 2 GB RAM NVIDIA EN210 SILENT GPU Windows 8 Drivers details: NVIDIA drivers - v331.65, told to be fully compatible with Win8 Currently I am installing Windows 7 and will be putting the older version of driver v320 to test, yet I'm really confused weather my GPU is dying or still on go.

• Why sizes are different, and what do they mean?

  - by Ramy

  I have a 1 TB hard drive that consists of one NTFS partition which I use to back up my data (no operating system). The size of all the data in it is : 726 GB, size on disk: 728 GB, and the used space when I check the properties is: 731 GB. There's a 5 GB difference between the size and the used space. Why is that huge difference there? What's the difference between these sizes? (size, size on disk, and used space) Is there a way to calculate the difference, and be sure the HDD is not messing around? Is that normal?

• How determine keyboard variation when manufacturer changes it

  - by Maksee

  When I decided to purchase Toshiba Z830, I specially noticed at photos that the keyboard was good for me (wide Enter, Left Shift, Backspace), you can query it at images.google.com, on most photos they're all wide. When I finally bought it (Z830-A2S), the keyboard was different, the Enter is narrow and the left Shift is "split" into Shift and backslash keys (probably 5% of photos at images.google.com). Is it normal for manufacturers to change this during the production cycle or this can be variations from different contractors? But the main point, is it possible to determine this from the full model name or somewhere else without visiting a store?

• Rate of UDP packet loss over WLAN

  - by Martin

  While testing something with TFTP I noticed lots of timeouts (and slow speed as result) when I used my WLAN - and no problems when using a network cable. A quick test program sending/receiving UDP revealed that there are about 3-5% packets lost. While it's obvious that WLAN has to be less reliable than LAN, I have no knowledge what loss rates are considered 'normal' - and when there is a need to further investigate the network infrastructure. Are there 'typical' packet loss rates on WLAN (and other network technologies e.g. PowerLAN, WAN, ...? Thanks

• USB Device With Embedded Fileserver

  - by Richard Martinez

  I'm attempting to access logs from a proprietary hardware box with no reasonable hope of modifying the software. There is a process on the device to dump log files to a flash drive on the USB port after entering a code sequence. Currently, analysis of the logs requires the following: Physical presence at the device Manual entry of the code sequence Removal of USB device Insertion of USB device into a normal Linux box I'm hoping there is some sort of device that can act as a USB mass storage device but simultaneously make it's contents available as a network file share (wired preferred). Does such a device currently exist? A combo hardware/software solution would also work.

• Video problem with Windows 7 Games

  - by Jordan 1GT

  I have a Dell xps M1330 which originally ran Vista, but I upgraded to Windows 7. When I try to run a Win 7 game like spider solitaire I receive the following message: "The game is running in software rendering mode. Hardware acceleration is either disabled or not supported by your video card driver which could slow down game performance. Make sure you have the latest video card driver installed and that hardware acceleration is turned on." I confirmed that hardware acceleration is turned on. When I go to Dell's site, I'm told there is no later video driver. When I run the game it runs very choppy. I wouldn't care, but I loaded a .pptx file which is doing strange things in normal view and I suspect may be related to the same video problem. Any ideas?

• Windows 2003 SP1 terminal server printers Disappear after reboot - HP laserjet 4240

  - by Alex

  had working PCL6 laserjet 4240 driver. needed to downgrade to PCl5, tried but did not get clean install. tried again and it seemed to work (this is 2003 enterprise terminal server SP2) Have over 40 working laserjets (5, 4000, 4100 and 18 of the 4240) After normal nightly reboot the 18 4240 printers were 'gone'. Worked w/Microsoft who said bad HP driver issues - weird since they work on other terminal servers. downloaded latest version, etc. from HP site and can NOT get to work. As soon as I install, then do a Net Stop Spool and Net Start Spooler the printer is 'gone'. Current workaround is to use HP 4000 PCL5 drivers for all of these 4240 printers.

• Why would the servers network type change from Private to Public?

  - by Phil Hannent

  Just found a fault with a server, other users have had problems connecting to it. The setting on the network card had changed from Private (domain) network to Public (the other option being Home). The switch to the network interface would have caused the firewall to block a lot of normal functions. I am guessing that since the event log showed no reason for the change that it might be due to a complete shutdown we had recently where someone powered up the machines, however the domain controllers might not have been booted up first. Any confirmation that this might be the case?
