  • Disabling networkmanager for a specific interface

    - by bdonlan
    I'd like to do some experimentation with hostap without disabling my primary wireless interface. How do I tell networkmanager to keep its hands off a specific interface or interfaces while allowing it to continue managing all other interfaces normally? I'm using Ubuntu 9.04. (Wasn't sure if this should go on superuser or serverfault, as networkmanager isn't much of a 'server' tool - if it belongs on serverfault please feel free to move it) Edit: I've tried adding this to /etc/network/interfaces: allow-hotplug wlan2 iface wlan2 inet static address 192.168.49.1 netmask 255.255.255.0 But this has no apparent effect, even after restarting NetworkManager. Here's my /etc/NetworkManager/nm-system-settings.conf: [main] plugins=ifupdown,keyfile [ifupdown] managed=false Edit[2]: Looks like I needed to restart nm-system-settings, then NetworkManager.

  • MySQL Daemon failed to start

    - by T. Brian Jones
    THE SETUP I'm running Linux CentOS on an Amazon EC2 instance. The MySQL data files are on an EBS Drive mounted at /data/ ( symlink - /var/lib/mysql /data/mysql ). Everything works fine in this setup. THE PROBLEM I'm trying to move everything from this EBS drive to a new drive. I umounted the /data/ drive, and mounted it at /data2/. Then I mounted the new drive at /data/ and copied everything over to it from /data2/. Everything on the system works great, except MySQL. Every time I try to start the MySQL daemon ( /etc/init.d/mysqld start ) I get a MySQL Daemon failed to start error.

  • need recommendation for running PHP/Zend based optimizer

    - by senorsmile
    Firstly, I must admit that I don't know much about setting up PHP beyond the basics. I have an Ubuntu 10.04 server system (hosted) running primarily as an FTP store for a commercial store software. The server that the commercial store is installed on is unfortunately not very reliable, and would like to move that to this Ubuntu 10.04 server. (We've already received permission from the store vendor to do this.) My problem is that they use Zend optimizer which is only compatible with PHP 5.2. I have tried a couple of "hacks" to downgrade PHP to 5.2, but it breaks so many other things that it doesn't seem worth it. My idea is to install some sort of container of Ubuntu 8.04 (like OpenVZ) on the server to house a native install of PHP 5.2 to meet the dependency of the store software. However, it appears that OpenVZ is no longer supported on Ubuntu. Is there another solution similar that I could run on a hosted server to installed a separate "container-like" 8.04 system?

  • Moving the OS X swap file to a faster drive

    - by Milky Joe
    I have a new Mac Mini that's running the latest version of Snow Leopard. The internal drive is a bit of a slouch. I'd like to move the swap file (or whatever it's called is OS X) to my faster external drive (Firewire 800, permanently connected). Is this possible? I've read that the old solutions aren't working in 10.6. My Mac has 2GB of RAM, so the swap file is used quite a bit when I'm doing intensive work (Photoshop etc).

  • How do I protect large file downloads through PHP and/or Apache?

    - by Eric
    We have some large files (1-8GB) that are not publicly accessible. Currently we're serving them up through a PHP script that buffers the files in 1MB chunks and writes it to the output. It's incredibly CPU intensive and slows the server down when only a few downloads are active. We want to move the file transfer work to Apache or a more efficient method. We are using cookie authentication. FTP downloads are out unless there's some way to authenticate FTP sessions through the existing PHP session cookie. Ideally we'd like something where we can use PHP to hide the link to the file while it passes off the file transfer work to Apache, which is no doubt far more efficient at HTTP file transfers than PHP. We want to be able to resume downloads as well. Any help is appreciated.

  • Hiding monitor from windows, working with it from my app only [closed]

    - by Mikhail
    I need to use a monitor as a "private" device for my special application, I want to use it as a flashlight of a sort and draw special patterns on it in full screen. I don't want this monitor to be recognized by OS (Windows 7) as a monitor. I.e. user should not be able to move mouse to that monitor, or change its resolution, or run screensaver on it or whatever. But I want to be able to interact with it from my application. Monitor is plugged using an HDMI cable to a video card (most probably nVidia). What is the simplest way to do this? All solutions are appreciated, including purchasing additional adapters or simple video cards, or any other special devices.

  • Booting a Windows 7 installation on different hardware

    - by tomfanning
    I'm in a situation where I could do with very quickly migrating a Windows 7 (RTM x64) installation from one machine to another. What options are open to me in terms of getting W7 to boot after the drive is picked up and moved from one box to another? I thought it was supposed to be a little less sensitive to this kind of move than XP, but it doesn't work - it is stuck in a reboot loop and never reaches a GUI. Tried a few things so far, none of which have worked: Changed SATA mode in the BIOS of the target machine between ATA and AHCI run Windows 7 Startup Repair tried safe mode, no change (I will keep this list up to date as suggestions come in) UPDATE: I can confirm this reboot loop is due to STOP error 0x0000007B, and these codes follow: 0xFFFFF880009A98E8 0xFFFFFFFFC0000034 0x0000000000000000 0x0000000000000000 UPDATE: I didn't get anywhere on this and I ended up just rebuilding the machine. I think it should be theoretically possible, so I'm going to leave the question open in case someone comes along in future with an answer.

  • How do you manage large web farms?

    - by Andrew Katz
    I have a quickly growing web farm running IIS 7 (30+ servers). All servers are identical copies of each other and all servers are physical. We update the software about once a month, and in the current process, we follow the following steps: Disable server from pool on F5 load balancer. Disable HTTP Keep-alives in IIS so connections drop quickly. Change default directory of website to new folder containing new binaries. Test server Enable HTTP Keep-alives. Enable server in F5 pool. Move to server 2 Microsoft used to have Application Center which was abandoned a while ago. They have made a second attempt with the Web Farm Framework, but this adds as much QA time testing the release package as it saves in the deployment. Has anyone seen a commercial off the shelf application that is tailored for managing and deploying to large web farms? Thanks!

  • Watch Flash video but block out part of it

    - by Ken
    I'm learning a foreign language. There are several online sites that have Flash video in the language I'm learning (e.g., Hulu), which is great. Unfortunately, they have English subtitles, which is (depending on who you ask) somewhere between "annoying" and "actively harmful to my learning". When I'm watching them in a window, I can just move them near the bottom of the screen, or put another window over them. That's awkward, but it kind of works. But I'd like to watch them full-screen, on my TV set. Full-screen Flash doesn't let me put any window on top of it. Is there a way to watch an online Flash video but block out part of it? I'll probably be using my Mac for this, but maybe Linux -- solutions for either one welcome.

  • Can a truecrypt container be moved on Fedora Linux?

    - by Thayananthan Narayanan
    I have created a truecrypt container (100GB) to store very important files with vital information hidden on my hardrive running Fedora Linux OS. Now, I want to move the container to portable hardrive. From what I read so far, you should be able to do it easily like any other file. However, I am running into problem. Fedora won't let me. It keeps giving me "Permission denied" error. I think I need to login as a root or superuser, but how do you do that on Fedora. What am I doing wrong?

  • What keyboard-friendly news readers exist for OSX? [closed]

    - by Chris R
    Possible Duplicate: Free Usenet reader for Mac OS X I'm interested in keyboard-navigation-friendly usenet clients for OSX. I have tried (and bought) Unison and Thunderbird, but both of these end up requiring a fair amount of mouse use to move around. What I want is something I can task-switch to, check my latest updates, and switch away from, all without having to take my hands off of the keyboard. I should clarify; this is for an internal, private nntp server, so Google Groups and sundry -- basically all web news readers -- won't do for me.

  • How can one select an application to switch to in task switcher with track pad (MacBook Pro, Mac OS

    - by index
    Three finger swipe left/right - Task switcher shows up (a horizontal bar with app symbols). Two finger swipe - highlights an icon and shows app name. ?? - switches to highlighted app. Since the highlighting is independent of the mouse cursor, a click doesn't work here without moving the mouse cursor. But I don't want this (locate mouse cursor, move the extra mile..). Maybe Better Touch Tool allows to configure a click to act as SPACE or RETURN in the task switcher? But how did Apple intend to use this?

  • How can I receive more traffic? My VPS fails!!!

    - by qtrix
    I have a web site - photo gallery. About 400 photos. Site on Gallery 3. mySQL. Hosted on VPS from myhosting.com (CPU 1792 MHz, 2048 MB RAM). Everything seems to be ok, but there is one big problem. Once traffic reaches ~ 20 people (online) - website start loading really really slow. Actually website can't be loaded about 30-60 sec. What should I do? Buy more RAM / CPU on the same VPS? Move to a dedicated server or maybe myhosting.com just sucks? What do you recommend?

  • Fast Bookmarking In Firefox

    - by Kije
    Making bookmarks in Firefox has become tedious. Can any one point me to a bookmarking extension that works as follows... Decide you want to bookmark a page Left click your way to the target bookmark folder Right the target bookmark folder to get a "Bookmark this page here" option. (It is this "Bookmark this page here" add on that I am looking for) (Edit the book mark title tags etc) Click done Currently you have to: Decide you want to bookmark a page Click on the bookmarks menu pulldown Click on "bookmark this page" Click on the "folder" pulldown Click on "Bookmarks tool bar" or "Bookmarks menu" Left click your way to the target bookmark folder (in a teeny window that that doesn't move the focus as you expand folders) (Edit the book mark title tags etc) Click "Done" That would be four (or five) steps to replace the seven (or eight) steps to make a bookmark in an existing folder. @Chris I assume you are referring me to "Read It Later" http://www.ideashower.com/ideas/launched/read-it-later/ I'll take a look.

  • Why is my USB-to-VGA'd monitor working, but not showing in Display Settings?

    - by Strilanc
    I have a USB-to-VGA adapter, which I use to connect a second monitor to my laptop (totaling 3 screens). It worked alright with Vista. I upgraded to Windows 7, and now it no longer works properly (I downloaded the latest drivers just to get it to work on 7). The extra monitor is detected and used to extend the desktop (I can move things onto it, etc), but is not shown within the Control Panel. This is annoying because now I can't changes its resolution, set its logical position to match its physical position, etc. Can I do anything, besides waiting for better drivers? I'm mainly concerned with moving its logical position. (I'd also like to understand how Windows can use a monitor it can't detect. Weird.)

  • Create a folder shortcut/redirection in Vista

    - by Ellipsis
    Given a plain old directory of files in Windows Vista, say "C:\OldFolder\", is it possible to move the contents of that directory to a new location, perhaps "F:\NewFolder\" and keep a shortcut-like 'virtual' folder at C:\OldFolder that will always redirect access to the updated location. Shortcuts work for users accessing through the GUI to some extent, but all application links to the old location won't work anymore even with a shortcut. For example, If MS Word tried to access C:\OldFolder\document.doc I would want Windows to simply rewrite it's request to F:\NewFolder\document.doc... I guess I'm basically looking for Apache's Mod_Rewrite for Windows Vista... any suggestions?

  • How to get pen input to draw?

    - by Cameron J
    I just got a crappy little Hyundai pen input module To use on a normal Windows 7 HP laptop, it works quite well with the Hyundai software, but that's in Chinese, and the input only stays on the screen for a second. When I try to use it in Paint, it just draws a dot, and switches back to an unclicked state, similarly, it's impossible to move a window. Is there ant way I can keep the click held down when the pen is touching the pad in order to draw, or is there any third party software anyone knows of that can do this?

  • Solution for storing sata drives outside of case

    - by Jeffrey Kevin Pry
    I have a system that has 8 sata disks in a software raid 5 array using mdadm. My issue is that I want to move the drives from inside of the computer case in order to cool more efficiently. I have looked all over the web and only seem to find enclosures that hide the drives connectors behind an estata port or some other internal raid controller. Basically what I want is an enclosure or equivalent that I can run independent sata cables to and either power as well, or have it have its own power supply. I have the sata ports on the motherboard available and don't want to limit io by using one port with a multiplier or the like. One final caveat, I am a college student on a budget and don't have a fortune to spend on such an enclosure. Thanks in advance for your help and advice.

  • Is it possible to convert striped logical volume to linear logical volume?

    - by JooMing
    I've a logical volume that is striped across three physical volumes. I had to move this logical volume to another physical volume. This worked nicely with pvmove command. However, I discovered later that the logical volume is still striped and now all three stripes are on the same physical volume. Is there any way to convert striped logical volumes to linear logical volumes? I'm using LVM2 on linux. I figured that the obvious possibility is to rename the striped logical volume, create a new linear logical volume, and then copy data over, but that requires taking the filesystem system offline for some time. Unfortunately, I can't do that before the next week. Is there any better alternative?

  • How to use an USB digitizer?

    - by Magnetic_dud
    Hello, i am in China now, and when i saw an USB digitizer (resistive), i bought it, thinking that i could be used as a mouse. When i connect it to my windows 7 rc1 laptop, the system properties says "pen input available" But, nothing happens when i touch the panel... i installed the bundled drivers, in chinese only, and NOT in unicode (so the text is garbled) When i install the driver, i get access to a special key on the tablet, "switch from pen input to mouse", and the driver will move the pointer according to the position on the tablet. (but no click) If i use the "pen mode", the computer will use a special chinese IME that is very awkard, i want to use the microsoft ime, and be able to draw/take notes on the screen There are "generic" drivers? Or just a plain mouse driver that will click when i press on the surface The tablet name is "qiancai"

  • Starting with administering a linux box

    - by Josh K
    I'm rather new to this, and I'd like to play with administering a linux box. Things I need to know how to do: Setup subdomains Setup FTP accounts Setup full domains / add domains MySQL setup / install / management LAMP setup / install / management This is probably going on a CentOS distro. I'd like links or a break down on how I can learn to do this. I am comfortable with a command line, but I'm trying to move from shared hosting to a VPS and would like to have some idea on how deep the water is before I do.

  • How can I make results of a formula values that can be filtered or use vlookup with Excel

    - by Burt
    I am having an issue in that I am using various formulas to move, split data, etc from various sources. The problem is when my final results post to the final destination that I want, I still need to either run advanced filters, or a vlookup with the results. I can’t do this because as an example if cell A1 shows a value of: A127 the actual cell content is: =RIGHT(A2,FIND(" ",A2&" ")-2) Everything I read said to copy and paste special values, but this doesn’t work for me as the idea is to have the formulas/macros run everything and eliminating cutting and pasting. In the case above I have a formula that pulls that info from a spreadsheet that is saved every week. Once it is pulled part of it is cut out in another column. I then need to run a vlookup on those results for data already contained on another tab.

  • Music Streaming Devices

    - by Skizz
    I'm looking for peoples opinion on wireless music streaming devices - something like this. I have an iTunes library hosted on an ubuntu server and I'm looking for something to allow me to listen to all the albums stored on it. Ideally, it should provide a good quality playback both over headphones and through speakers so that everyone can hear it. It doesn't need to be ultra-portable - being able to move the system and plug in a mains lead should be enough, so a single, integrated unit is preferable. One product per answer please and if you've used a product, vote it up or down depending on whether it's any good or not. Use comments to highlight good/bad points.
