• Easily tell if focused on VirtualBox window?

  - by Benjamin Oakes

  Is there a way to make it very obvious that my VirtualBox window isn't in focus? The problem I'm having is switching between workspaces on Ubuntu or OS X and then trying to type in my Windows virtual machine, only to find that it's not in focus. The Windows window looks like it's in focus (based on the title bar), but I'm actually typing in Firefox on the host machine, for example. It's even worse because the Windows text insertion cursor is blinking to show focus. Ideally, I'd like the VM's display to get unsaturated (e.g. a "partial" grayscale) when not in focus, just to prevent this keyboard-focus problem. Other options would be fine too, as long as I don't have to second guess where my focus is. I'm not using the seamless mode -- the display is all within a window.

• Bad Mumble control channel performance in KVM guest

  - by aef

  I'm running a Mumble server (Murmur) on a Debian Wheezy Beta 4 KVM guest which runs on a Debian Wheezy Beta 4 KVM hypervisor. The guest machines are attached to a bridge device on the hypervisor system through Virtio network interfaces. The Hypervisor is attached to a 100Mbit/s uplink and does IP-routing between the guest machines and the remaining Internet. In this setup we're experiencing a clearly recognizable lag between double-clicking a channel in the client and the channel joining action happening. This happens with a lot of different clients between 1.2.3 and 1.2.4 on Linux and Windows systems. Voice quality and latency seems to be completely unaffected by this. Most of the times the client's information dialog states a 16ms latency for both the voice and control channel. The deviation for the control channels mostly is a lot higher than the one of the voice channels. In some situations the control channel is displayed with a 100ms ping and about 1000 deviation. It seems the TCP performance is a problem here. We had no problems on an earlier setup which was in principle quite like the new one. We used Debian Lenny based Xen hypervisor and a soft-virtualised guest machine instead and an earlier version of the Mumble 1.2.3 series. The current murmurd --version says: 1.2.3-349-g315b5f5-2.1

• How to start wuala on the linux commandline with auto login

  - by mit

  When i start wuala on the linux commandline like this, it logs me in and the folder is mounted: wualamcd login username password enableAutoLogin I can shut it down from another console typing wuala shutdown But how do I actually use the auto login that I just set using the enableAutoLogin switch? What is the command to start it again, so it logs in but does not need the password? I tried wualamcd login and wuala starts but no one gets logged in. Auto login in gui mode works fine. This is 32 bit linux with openjdk 6 JRE.

• Windows Vista not indexing files

  - by kevin

  I'm using Windows Vista's search index service to quickly launch programs by typing "windows key" +"name of program". However I'm having a hard time trying to understand why certain files won't appear. I want to launch "pageant.exe" located in "C:\Program Files\Putty" with this method but it doesn't show up in the results. In the index search options I said I wanted to index the "Start menu" and "C:\Program Files". I've checked that .exe files are indeed indexed and they are. I've also tried to completly rebuild the index with no luck. What am I doing wrong ?

• Network access lags for Win7 when server network utilization is high

  - by Jeff Miles

  We have a Dell PE2950 file server running Windows 2008, hosting a DFS namespace of ~1.2 TB. This server has two Broadcom 1Gbps NICs teamed together. When there is high traffic going to the server across the network (greater than 200 Mbps), any Windows 7 client accessing a DFS share at the time experiences severe performance problems. For example: Computer A has an AutoCAD drawing opened directly from the DFS share. Performance is normal, not causing any issues. Computer B begins a file transfer, putting a 11GB file onto a different DFS namespace, on the same server Computer A immediately notices lag while using AutoCAD. The cursor momentarily freezes within AutoCAD every 10 seconds or so, and any browsing of the DFS share is extremely slow. Computer B completes file transfer, and performance resumes to normal for Computer A. This is only affecting Windows 7 clients, using a variety of hardware (desktop + laptop). All of our Windows XP clients see no performance impact during the file transfer. Things I have tried with no change: Had Computer A work from an entirely different RAID array from the file transfer destination Updated NIC drivers on clients and server Enabled TCP offload and receive side scaling on the server NIC (previously disabled when the issue began) Antivirus disabled during file transfer I am currently having a user test applications other than AutoCAD when the file transfer occurs, and will update the question with that result. Does anyone have any recommendations for resolution or additional troubleshooting steps?

• Tab Completion In Emacs shell-mode SSH Sessions

  - by Sean M

  My current use pattern of emacs results in my having several shell-mode buffers open, each running an ssh session. I am running into an issue with this, though - when I try to tab-complete file names and other things in my remote session, the shell attempts to use completions available on the local machine instead of on the remote machine. For example, if the file ~/foobar exists on the local machine and ~/frob exists on the remote machine, typing in ~/f and pressing tab results in ~/foobar instead of completing correctly. If I use ssh outside of emacs and try the same thing, I get the correct completion of ~/frob instead. How can I get tab-completion to complete the way it does in normal ssh sessions ?

• Are Snow Leopard text substitutions scriptable?

  - by yonatron

  I prefer using typographical quotation marks when possible, so I love the Smart Quotes part of Snow Leopard’s text replacement feature. But there are a few cases in which I need to toggle it, and it’s a pain to do so from the contextual menu when I’m typing. Is there any way (preferably via AppleScript, but I can deal with other suggestions) to toggle specific types of text replacement for the frontmost text-input control? And if so, what’s a good way to assign it to a globally-accessible keyboard shortcut (via 3rd-party app if necessary)?

• Publishing and setting permissions to a Linux share to AD

  - by blsub6

  I have a Linux share that I want to publish to users on my Active Directory domain. I'd like to be able to control the permissions to access that share using security groups. So say I have a share named "Share" on my Linux machine named "Linux" with IP address 192.168.1.2. I publish \\192.168.1.2\Share in AD and make it so that only people who are part of the "IT" security group can access it. What's to stop anyone who's not in the "IT" security group from just going to explorer and typing in \\192.168.1.2\Share or \\Linux\Share into their Explorer to access this share? Do I need to set up permissions on the Linux file server?

• Server 2008 won't run executables from CMD prompt without .exe extension

  - by Dan

  On one of our production server 2008 boxes, I cannot run executables from a CMD prompt without supplying the full filename, including the '.exe' extension. For example, when running "java" produced the usual "is not recognized as an internal or external command" message, I assumed I had borked the path and/or java_home variables. However, even navigating to the %java_home%\bin directory and typing "java" produced the same error. If I type "java.exe" instead, all works perfectly. The problem does not only affect java.exe. Even Microsoft executables suffer the same problem -- ping fails, ping.exe works; ipconfig fails, ipconfig.exe works; manually created batch file 'test' only works when invoked explicitly as 'test.bat'. Any bright ideas?

• Accessing local files through an http:// address

  - by RexE

  I would like to access a folder of mp3 files on my local Windows machine through http:// addresses. For example, typing http://localhost:9999/songs/test.mp3 into my browser would play test.mp3, which sits in a specified folder on my C: drive. What is the very simplest way to do this? (Background: a program I'm using wants me to enter the URLs of these files, but assumes they are remote and accessed over http. It doesn't accept URLs of the form file://C/Users.... So, I'd like to give these local files addresses that makes them "look" remote.)

• FFmpeg convert video w/ dropped frames, out of sync

  - by preahkumpii

  I recorded a video using Bandicam with the MJPEG encoder to get the least amount of lag. Now, I am trying to convert that massive file to a h264 avi using ffmpeg. I know there are dropped frames in the video stream...more than 100 in the first two minutes, which I assume is simply because Bandicam dropped some when it couldn't keep up. So, when I convert the file to h264, the video and audio are out of sync, and appear to be more and more out of sync as output video progresses. Here is my basic command in ffmpeg: ffmpeg -i "C:\...\input.avi" -vcodec libx264 -q 5 -acodec libmp3lame -ar 44100 -ac 2 -b:a 128k "C:\...\output.avi" I have tried EVERYTHING I can think of including: -itsoffset [-]00:00:01 Tried this before and after input file. This doesn't work because as the video progresses it becomes more and more out of sync. -async 1 Doesn't work. -vsync 1 Doesn't work, but it does show dropped frames being duplicated. Two inputs of same file with mapping using -map 0:0 -map 1:1. Doesn't work. The source plays just fine. Any ideas how to convert it with ffmpeg and keep the audio and video synced? Thanks.

• Why might powerpoint not let me adjust the height of a table row?

  - by YGA

  Powerpoint is fighting me every time I try to adjust the height of a table row, and I'm wondering if folks have ideas why that might be the case. See the attached picture; the Argentina row is of height 0.41", while the Nicaragua row is 0.61". Whenever I change to change the Nicaragua row (either by manually moving the row line, or by typing in a new height into the box) powerpoint immediately resets it. The difference? The Argentina row I typed in directly, while the Nicaragua row I pasted in from Excel. Thoughts what might be the difference?

• Removing past searches from Google Chrome's omnibar

  - by Ram Rachum

  One time I searched for Orange Juice in Chrome's Omnibar. Now, every time I start typing Orange, I get the search suggestion: How do I get Chrome to stop offering me this search suggestion? If I need to edit some config file, I can do that. Please don't post answers if you haven't ensured they work first. (This is intended to prevent people from answering "Press Shift-Delete.") Clarification: I'd prefer a solution in which I can selectively delete entries, not just by time segment. I also prefer a solution that does not involve cancelling any Chrome functionality.

• Citrix XenApp application does not have keyboard focus when launched

  - by Jason Pearce

  On new or existing Citrix XenApp 4.5 servers, I am having problems streaming the Allscripts Pro EHR application via the XenApp web interface. When users launch the application via the Citrix XenApp web interface, the application does not have focus, preventing users from typing in their username and password. If they use their mouse to select either the username or password fields, they still cannot enter any text. However, if they do any of the following actions, they can then enter in their username and password and the application runs without problems: Click on the Login button with empty fields. Logon fails but they can then enter their credentials. Minimize the login window and then maximize it. They can then gain keyboard focus to enter their credentials. What might be preventing this particular application from having focus when it launches?

• Port forwarding not working?

  - by rphello101

  I'm trying to set up an Apache Server to be accessed publicly. I'm using a Netgear R4500 router hooked up to a Motorola SB6121 modem. I can access my server on my computer by typing in my IP address. After following the instructions to forward port 80 so I can access the server from other computers, it does not work (see image). I get "This webpage is not available". I am forwarding to the IP address of my computer. Using this Network Port Scanner Tool, it says "80/tcp filtered http", which, as I understand it, means forwarding did not work correctly. In my Apache httpd file, I have: ServerName 192.168.1.13:80 and Listen 192.168.1.13:80 Anyone know what's wrong or have something I can try? click to enlarge

• How to fix: mac keyboard ignores "first" key pressed

  - by lexu

  UPDATE 2012.03.19: the MBP described in this post is now broken and recycled (logic board fried). The replacement doesn't manifest the same problems. I tend to believe the problem originated in the keyboard firmware of the old MBP. Every now and then, usually after I haven't pressed a key in some time, sometimes minutes, sometimes seconds, my MBP will "swallow" the the first key I press ... say I'm logging into "superuser.com" .. I start typing my username and the textbox will show "exu" instead of "lexu" This is driving me nuts! My guess is the keyboard or it's controller goes to sleep and fails to wake up propperly ... What can I do about this? PS: I've already installed "MacBook, MacBook Pro Keyboard Firmware Update 1.0"

• MacPro will freeze after first startup and first time screen saver activates

  - by Rob Segal

  I've run into a bizarre situation every time my MacPro first starts up in the morning when I get to work and the screen saver activates for the first time. When I try to deactivate the screen saver hitting the keyboard or mouse nothing will happen. At best I will get one of the following... Able to move the mouse but clicking does nothing Login prompt will show up but typing on the keyboard does nothing At worst the screen will be fully locked. In all cases I will have to reboot my machine to get it to work again. After this initial restart the machine is fine for the rest of the day. Anyone encountered something like this before?

• Stop Touchpad from disabling itself when I press any keys?

  - by ApprenticeHacker

  I have an acer E1-571 laptop, with an ELAN Smart Pad. Unfortunately the "Smart" pad is a bit too smart. It automatically disables itself while I am pressing any keys. This is useful when typing. However it does not allow me to play games that use the mouse for scrolling such as Counter Strike and GTA San Andreas as the touchpad gets disabled when I press any key. I tried to find an option or check-box of some kind that would disable this behavior in the ELAN Smart Device Driver's Properties and the Windows 7 Control Panel, but to no avail. Any ideas?

• Using terminal vs KDE in linux?

  - by Ke

  Im used to using nautilus within centos but have recently just got a VPS and quickly realising that using a KDE is unacceptable in this environment. Although I do find it so much quicker doing things like folder permissions in KDE rather than typing it all out in the terminal? Everyone I speak to says, use the terminal and I should learn this way as opposed to using the KDE, but theres certain things I just dont get How is it possible to make quick changes to scripts and viewing them in a browser etc , without a mouse or using KDE? and only using a terminal?? I am wondering how to develop websites just using the terminal??? How can it be quicker to type out/view permissions etc in the terminal when its instant and just a few clicks in the KDE? Any thoughts are much appreciated. I would love to understand the benefits but just cant seem to see them right now. Cheers Ke.

• I get regular power surges and my UPS ticks a lot due to a welding plant. Is this good or bad?

  - by EApubs

  In our home, there is a mechanic who often use a welding plant. When he use it, I think we get a power surge. My UPS ticks madly (not beep, it ticks). Sometimes, I even lose power to the keyboard. When typing, some keys get missing. 1) My question is, is it good for the computer? The UPS claimed to have surge protection. But isn't it working? What should I do to protect my PC? 2) The second question is, I also have a broadband router which is not connected to the UPS. Will it be effected?

• Impossible to stop raid device

  - by Traroth

  I'm trying to stop a RAID disk in order to replace it by a new one, as this one is not working properly. I'm typing mdadm --stop /dev/md1, and I'm getting an error message: mdadm: fail to stop array /dev/md1: Device or resource busy I'm getting this message even if I reboot the server, and I can't see a process that could cause this. The server is working under a Debian with a 2.6.18-4-amd64 kernel. Could you help? Edit: Mote details about what my colleague tried out. After unmounting sda1, the command mdadm --remove /dev/md0 /dev/sda1 worked. But now, we still have an error message after mdadm --remove /dev/md1 /dev/sda5: mdadm: hot remove failed for /dev/sda5: Device or resource busy I still don't understand completly how the different partitions are mounted, so I suppose there is something I don't understand in the currenct situation...

• KDE doesn't start up anything else

  - by Shane

  I just installed KDE under Arch Linux. Problem is, nothing is starting up right with it - no window manager, no panels, nothing. All I get is a small terminal window in the bottom right corner of the screen, which I'm assuming is konsole. From that single window I can do things like start kwin or launch programs whose names I happen to know (like chromium or firefox), but I don't have a panel for starting programs or switching between programs. It doesn't matter whether I start kdm through inittab or manually by typing # /etc/rc.d/kdm start. KDM looks great, but once I log in as my normal user I just get a console window with no decoration. Is there a startup script for KDE somewhere that needs to run, and usually has a bunch of programs by default - like a window manager, panels, widgets, and all the normal background programs that run in an ordinary GUI? If so, how can I "restore" the default behavior?
