• My SSD stopped working as it ends up in blue death right after windows 7 launches, how can I reset it for new windows install?

  - by HattoriHanzo

  As I mentioned in the title my SSD suddenly started to fail as after launching Windows 7 it goes straight to completely idle and after a few minutes it goes to blue death and restarts. I have an another HD with a windows xp on it and it works fine and I can also see the SSD and can access everything on it. Windows 7 on the SSD does work in safe mode though yet I didn't manage to find out what causes the problem. Since I can sill access the files and save them to another HD I'm looking for the best way to wipe and reinstall Windows 7. I have yet failed to find an easy to follow (or even understand) guide, different sources on the internet recommend different ways of doing this. And some guides are just simply full of terms I have no clue about. It's an OCZ Vertex 2 120GB. I"d very much appreciate if someone could give me an advice on what I should do, preferably in a way so I could regain the best possible performance as well. it doesn't matter if I don't understand the science behind it as long as I can follow the steps. Thanks!

• Is there a utility to visualise / isolate and watch application calls

  - by MyStream

  Note: I'm not sure what to search for so guidance on that may be just as valuable as an answer. I'm looking for a way to visually compare activity of two applications (in this case a webserver with php communicating with the system or mysql or network devices, etc) such that I can compare the performance at a glance. I know there are tools to generate data dumps from benchmarks for apache and some available for php for tracing that you can dump and analyse but what I'm looking for is something that can report performance metrics visually from data on calls (what called what, how long did it take, how much memory did it consume, how can that be represented visually in a call stack) and present it graphically as if it were a topology or layered visual with different elements of system calls occupying different layers. A typical visual may consist of (e.g. using swim diagrams as just one analogy): Network (details here relevant to network diagnostics) | ^ back out v | Linux (details here related to firewall/routing diagnostics) ^ back to network | | V ^ back to system Apache (details here related to web request) | | ^ response to V | apache PHP (etc) PHP---------->other accesses to php files/resources----- | ^ v | MySQL (total time) MySQL | ^ V | Each call listed + time + tables hit/record returned My aim would be to be able to 'inspect' a request/range of requests over a period of time to see what constituted the activity at that point in time and trace it from beginning to end as a diagnostic tool. Is there any such work in this direction? I realise it would be intensive on the server, but the intention is to benchmark and analyse processes against each other for both educational and professional reasons and a visual aid is a great eye-opener compared to raw statistics or dozens of discrete activity vs time graphs. It's hard to show the full cycle. Any pointers welcome. Thanks!

• Can not boot windows XP from cloned hard disk - what can I do?

  - by Martin

  My configuration: a PC (some years old) with MSI K8N-Neo-4F Motherboard, 1 GB RAM. Disk 1 (Maxtor, SATA II, 250 GB): 2 Partitions, on Partition 1 (48 GB): Windows XP Professional (NTFS) on Partition 2 (190 GB): data (NTFS) I wanted to have a larger and faster disk (the PC is incredibly slow and permanently the disk is rattling when I try to open an application or during Windows startup), so I took Disk 2 (Seagate, Sata II, 500 GB), installed in the PC, created at first a 400 GB-partition at the end of the disk and cloned the data to it, which worked well Installed a swap partition and a partition for Ubuntu Linux 12.10 on the first "part" of the disk so I was able to boot Linux and the old Windows XP with the Linux "System selection" at startup. Now I wanted to move Windows XP to the new disk, deleted the Linux partitions cloned Windows XP to the new disk (with free tools - EASESUS), left both disks in the PC and tried to select the new hard drive during boot as boot partition. This did not work, the PC refused to boot from this second disk. I tried many things like making the boot partition on the 2nd drive "active" in the Windows System Preferences modifying the boot.ini file to boot from the second disk - tried to boot from it, but ended with an error message stating that it was not possible to boot from this disk because of a hardware failure or something else or so removing the original disk and plugging the new one on the same SATA port as the original one - also booting failed with an error message repairing the MBR by booting into recovery mode from the Windows XP Installation CD-ROM, selecting the second disk and doing "FIXMBR" which said that everything was fine with the MBR. after that at least the PC tried to boot from the newer disk and then startup was hanging during the blue screen with the Windows Logo.... no luck. ... deleting the cloned partition and cloning again - this time with Macrium Reflect Free version... - no success during booting. I tried a lot of things with no success, so I wonder what I am doing wrong?! What could I do to successfully clone my Win XP partition to replace the original disk by a larger one which is bootable.

• Outlook 2010 Crashing Unpredictably

  - by cbkadel

  Very often when I open up Outlook 2010 and start doing actions in it, it will hang and become non responsive. I have tried letting it finish, but it never does come back (up to 20 minutes of letting it try). I generally have to restart Outlook and try again. Usually after about an hour of doing this, Outlook somehow snaps out of it and works for the rest of the day. It's generally in the morning (though I doubt that's the key variable). Generally, the emails that cause problems are HTML/formatted, but not always. What I've done so far to troubleshoot: Install Latest Outlook Hotfix (I think Dec 14, 2010) Start Outlook in Safe Mode Neither of those steps seem to make a difference. Usually - after about 10-15 restarts of Outlook on any given day, then it starts working thereafter. My next step is to uninstall/reinstall Office 2010, but I'm hoping someone has seen this and knows what to do about it - though not sure. My configuration is like this: Microsoft Online Services (using Microsoft's Sign In App) - Connecting to Exchange I have two other Exchange accounts in this profile (new feature in 2010) connected through Outlook Anywhere. Life Meeting Conferencing Add In I've disabled the People tab/add in. I've disabled the "Send to Bluetooth" add-in. Not sure what else to do. Thanks in advance.

• Computer freezing while watching Flash videos from net

  - by t3st

  I have a Windows 7 home basic, while watching videos from net (within 5 minutes) computer starts to freeze and shows 100 percent CPU usage. I first thought it's a browser issue but watching videos from different browsers also has the same issue. My system runs the latest Firefox browser and all my plugins (including Flash) is up-to-date. After this when I shutdown/restart the computer it will go to the login window with out any problem. From there when I tried to log in to any account, the system starts to freeze and again I have to start and run Windows in safe mode (which doesn't show any problem). I read it in an article to do these steps CMD->sfc/scannow chkdsk after that only my system works normally, even now I can't watch any videos on the net otherwise it starts freezing( I can watch downloaded videos in computer without a problem) and have to do the whole process once more (which takes a lot of time). while running sfc/scannow its showed results that some of the files are corrupted and it could not be repaired. Can this be the cause for freezing of my computer while running Flash videos? or is it a hardware related problem? What different steps do I have to take to correct those corrupt files? System restore works only some times.

• rdp allow client reconnect without password prompt after several hours

  - by Tom

  Let me describe the setup first: client PC with several rdp sessions to local servers, all opened from saved rdp sessions with stored passwords, using the standard windows rdp client. several windows servers on the LAN, with varying server OS: windows server 2003, 2008, and even 2012 now. When I log onto my PC I open up rdp sessions to all those servers, and keep them open all the time for various reasons. Overnight the client PC is put into sleep or hibernate mode, thereby braking the rdp connections. On the next day when I wake the client PC and login again, the rdp sessions automatically try to reconnect to the servers, and this leads to the question: starting with server 2008 something apparently changed in the rdp server config, as all servers with 2008, 2008r2 and 2012 will prompt for the password in the rdp session, whereas the 2003 server rdp connections will re-establish without the password prompt. Apparently there is a timeout setting on 2008+ that, when exceeded, requires a reauthentication. Is there any way to setup the 2008+ servers to behave like 2003 did? I'd like the rdp sessions to reconnect without a password prompt even after a several hour disconnect.

• Adding file to /etc/cron.d doesn't make it run (ubuntu 10.04)

  - by tom

  If I scp a cron file into /etc/cron.d it doesn't run unless I edit the file and change the command. Then crond seems to pick up the cron file. How can I make cron reload its cron files in ubuntu 10.04? 'touch'ing the file doesn't work nor does 'restart cron' or 'reload cron'. My cron file is set to run every minute and logs to a file. Nothing ends up in the log file until I edit the command, and there's no entry for it in /var/log/syslog I'm stumped. Here's my cron file saved to /etc/cron.d/runscript # Runs the script every minute. This is safe because it will exit with success if it's already running * * * * * www-data if [ -f /usr/local/bin/thing ]; then exec /usr/bin/php /usr/local/bin/thing mode:prod -a 14 -d >> /var/log/thing/mything.log 2>&1; else echo `date +'[%D %T]'` "Thing not deployed.

• Grayed-Out Sleep and Hibernate Options on Windows 7 After Updating Graphics Driver

  - by Maxim Zaslavsky

  I have a Gateway M275 Tablet PC, on which I've installed Windows 7 Ultimate. The laptop is quite old, so there aren't any Win7 drivers for it, not to mention any Vista drivers. Win7 has been working for some time, but I noticed that my video output wasn't working. I went into Device Manager and found that I didn't have a driver for my video card: it just recognized it as the standard one. I searched online and found an XP driver for it, released by Gateway. Device Manager accepted this driver and prompted me to reboot. After that, I noticed that my Sleep and Hibernate options in the Shut Down menu have been grayed-out. I looked online and found that many people are attributing this to display drivers, as such an old driver would surely not be compatible with the standby procedures Windows 7 uses. To make it clear: I was able to Sleep and Hibernate before updating the drivers; now, I can't. Running powercfg /a gives me, "An internal system component has disabled this standby state," for each available standby mode. Is there some way that the driver can be modified to support hibernation? The new driver fixed my video output problem, but I guess hibernation is more important for me. If not, what steps should I take to remove the driver and just leave the standard Windows one, which previously supported hibernation and sleep on this computer? Thanks in advance.

• Assigning cores to VM in vSphere

  - by user114933

  Complete vSphere newbie here... Background: So, I have a 12 core machine with 24 VMs on it. Currently, all the processing power is shared between these VMs equally. The question: Can I configure one VM to be given two CPU's worth processing no matter what's happening on the other machines? My Research: I tried two things in vSphere... I set the reservation and limit on one VM to equal the same as two cores. To test if my objective was being reached, I measured the time it would take to gzip a file when other VMs were running nothing and when other VMs were running CPU intensive operations. I expected the time to gzip the file would be the same because this VM gets priority for some processing. Unfortunately, the time taken to gzip the file when other VMs were running something was significantly more than when other VMs were not running anything. I tried setting the Hyperthreaded Core Sharing mode to Internal hoping that this would mean that my VM would get at least an entire core to itself. This did not work either. Thanks in advance!

• Wireless Access Point stopped working

  - by Alex Pritchard

  I have a simple LAN set up at home using a Linksys WRT54GSV4 as my primary router and an Encore ENHWI-2AN3 as an access point. I connect the Encore to the Linksys by running a cable from one of the Linksys LAN ports into the Encore WAN input. I originally configured this using the Encore setup wizard, setting the device up in AP Router Mode. It detected the input network and worked about as expected, creating a second network that used my primary network to connect to the internet. It worked fine for about 2 weeks, then abruptly cut out today. I checked to make sure the network was still live through the cable going into the Encore (provides internet when connected to a laptop directly) and that devices are still able to connect to the network being broadcast by the Encore. When I try to rerun the connection wizard on the Encore, I receive the message "No Services found in WAN port." The WAN Settings is no longer retrieving a dynamic ip from the line. I tried providing a static IP, assigning an IP address within the subnet range of my primary router that wasn't being used and pointing the Default Gateway to the Linksys IP, but this did not work either. When I plug the cable into the WAN port, an internet light comes on that is not lit when a live network is not connected. I've tried doing a hard reset on the Encore (held down the rest button until the lights flashed, reconfigured from scratch), but the WAN settings are still not detected. Also tried powering off and on the modem, linksys, and encore. Any suggestions would be appreciated!

• Clicking far away in vim in tmux in urxvt

  - by paps

  I use vim inside tmux inside urxvt, and the mouse works perfectly well for clicking and selecting text, except when I want to click too far to the right. It seems to be related to the distance in number of columns from the left. When I go beyond column ~200 (not sure about the exact number), clicking simply does nothing. Note that it's not related to a vim window: with two vim windows taking ~150 columns each, clicking will not work after the ~50th column in the second window. It's related to the whole vim session. Also note that clicking far away in a big tmux pane (200 columns) works perfectly. In my .tmux.conf I have this line: set -g default-terminal "screen-256color" and in my .vimrc I have this: if &term =~ "^screen" autocmd VimEnter * silent !echo -ne "\033Ptmux;\033\033]12;7\007\033\\" let &t_SI = "\<Esc>Ptmux;\<Esc>\<Esc>]12;5\x7\<Esc>\\" let &t_EI = "\<Esc>Ptmux;\<Esc>\<Esc>]12;7\x7\<Esc>\\" autocmd VimLeave * silent !echo -ne "\033Ptmux;\033\033]12;14\007\033\\" end It changes the cursor's color depending on the editing mode of vim, and it works, meaning that tmux really sets $TERM to "screen-256color" — but I don't know if this has any relevance with my mouse problem. I'm running Ubuntu 12.04, vim 7.3, tmux 1.6 and rxvt-unicode 9.14. Does anybody have an idea about what is causing this problem? Thanks.

• Can you help me understand my SATA/RAID options?

  - by andrz_001

  I've a gigabyte GA-M720-US3 motherboard. Recently, I noticed the following during boot: IDE channel 0 Master (none) IDE channel 0 Slave (none) IDE channel 2 Master (my hdd) IDE channel 2 Slave (my dvd drive) IDE channel 3 Master (none) IDE channel 3 Slave (none) Of course, the same information is contained in the BIOS/CMOS. The HDD is connected to the mobo via a SATA(2?) cable at the port(?) labeled SATA2_0. The DVD drive is connected by a similar cable at SATA2_1. Why doesn't the information displayed during the boot and in BIOS reflect how I plugged the cables in? I mean, why "none" for channel 0 when there is something in SATA2_0. (or is that serious naivete on my part!?) Where's Channel 1 master and slave? Since these are SATA cables and not the IDE ribbons from a time ago, why the whole master/slave declaration during boot and in BIOS? Should my BIOS reflect the fact that these are SATA cables? I mean, in BIOS, should the "Onchip SATA mode IDE" be set to RAID or AHCI instead of IDE? Any replies, answers, suggestions, links, tips will be much appreciated. Thank you in advance!

• nginx logrotate config

  - by TomOP

  Whats the best way to rotate nginx logfiles? In my opinion, I should create a file "nginx" in /etc/logrotate.d/ and fill it with the following code and do a /etc/init.d/syslog restart after that. This would be my config (I havn't tested it yet): /usr/local/nginx/logs/*.log { #rotate the logfile(s) daily daily # adds extension like YYYYMMDD instead of simply adding a number dateext # If log file is missing, go on to next one without issuing an error msg missingok # Save logfiles for the last 49 days rotate 49 # Old versions of log files are compressed with gzip compress # Postpone compression of the previous log file to the next rotation cycle delaycompress # Do not rotate the log if it is empty notifempty # create mode owner group create 644 nginx nginx #after logfile is rotated and nginx.pid exists, send the USR1 signal postrotate [ ! -f /usr/local/nginx/logs/nginx.pid ] || kill -USR1 `cat /usr/local/nginx/logs/nginx.pid` endscript } I have both the access.log and error.log files in /usr/local/nginx/logs/ and want to rotate both daily. Can anyone please tell me if "dateext" is correct? I want the log filename to be something like "access.log-2010-12-04". One more thing: Can I do the log rotation every day on a specific time (e.g. 11 pm)? If so, how? Thanks.

• Why is my new PC so slow at startup?

  - by rumtscho

  Bought a new PC this weekend, and it works really good. Only I have one big problem: startup time. Its BIOS needs 62 sec to load, then from Grub start to pw entering screen it's another 26 sec. I think this is a lot, because my old PC needs 34 sec for BIOS and another 8 sec to pw screen. After I enter the pw, the desktop is usable with practically no delay on both. The new PC is a core i7-930, running a Lucid Lynx 64 bit from a Intel Postville SSD (no internal HDs). The old PC is a Pentium 4 celeron (forgot the clock speed) running a Lucid Lynx 32 bit from an ATA 100 hard drive. Neither PC is overclocked. The new one has boot sequence 1.DVD ROM, 2.SSD (connected over SATA in AHCI mode), 3. removable drive. The old one boots from 1. DVD ROM, 2. HDD, 3. Floppy. Neither has a second OS installed. The new one has less software installed than the old one (I think), but the boot time difference was noticeable even before I made any installs. As far as I know, just the SSD should be enough to make a noticeable difference in boot time. I thought that having a good mainboard on the new PC as opposed to the basic office model on the old one would also mean a faster loading BIOS. If these assumptions are right, I guess I must have misconfigured something in the BIOS of the new PC. How should I configure it for a fast boot? It has an ASUS P6X58D board with an AMI BIOS, if you need the BIOS revision number I could post that too.

• can't register a soft phone to asterisk11

  - by Tom

  I have a VM (on oracle vbox) running Fedora17. I've installed asterisk 11 on it from sources. I've followed the wiki for installation (https://wiki.asterisk.org/wiki/display/AST/Creating+SIP+Accounts) to the letter. The ip on the VM machine running fedora is 192.168.1.7 and I can ping it from the host machine (Ubuntu 12.04), which is at 192.168.1.2 I've tried registering with ekiga with the following settings: user: [email protected]. Password: verysecretpassword registar: 192.168.1.7 but I'm getting an error "transport fail". Also, while trying to register I'm logged in to the asterisk CLI with verbose level 3 and debug level 4 and nothing appears. some more relevant data: I've added the following code to the end of my sip.conf.sample file: [demo-alice] type=friend host=dynamic secret=verysecretpassword context=users deny=0.0.0.0/0 permit=192.168.1.0/255.255.255.0 [demo-bob] type=friend host=dynamic secret=othersecretpassword context=users deny=0.0.0.0/0 permit=192.168.1.0/255.255.255.0 After I changed the sip.conf.sample file, I've created a copy of it and named it sip.conf. then I logged in to the asterisk CLI and typed sip reload. Then I'm trying to register and ekiga client from my host machine at 192.168.1.2 but it doesn't work and nothing appears on the asterisk CLI while in verbose mode level 3. BTW, If there is missing information about my question, please don't close it. comment about what you need to know and I'll edit it in to the question. tnx.

• Get Matrox Millenium video card working in Ubuntu 9.10

  - by wcoenen

  I have installed Ubuntu 9.10 on an old PC and it is mostly working, except for some heavy drawing defects that show up whenever I start dragging a window or scrolling inside a window or menu. It looks like the video driver copies the rectangle being moved to the wrong location. I have taken a look in /var/log/Xorg.0.log and the following line shows the detected video card: (--) PCI:*(0:0:8:0) 102b:0519:0000:0000 Matrox Graphics, Inc. MGA 2064W [Millennium] rev 1, Mem@ 0xf9800000/16384, 0xfb000000/8388608, BIOS @0x????????/65536 (==) Using default built-in configuration (30 lines) (==) --- Start of built-in configuration --- Section "Device" Identifier "Builtin Default mga Device 0" Driver "mga" EndSection How do I fix the drawing defects? It turned out that the 24 bit color depth (automatically selected by ubuntu 9.10) was the problem; apparantly the mga driver doesn't handle this well for cards with little memory. I took the following steps to resolve the issue (you can skip the first three steps if you already have a semi-working xorg.conf file): Reboot ubuntu in recovery mode, to get a root console without X running. Run Xorg -configure to generate a xorg.conf.new file Copy the file to /etc/X11/xorg.conf with cp xorg.conf.new /etc/X11/xorg.conf (assuming it didn't exist yet; that's why I generated it) Open the new config file with sudo nano /etc/X11/xorg.conf and make sure the screen section is configured for 16 bit color depth like this: Section "Screen" Identifier "Screen0" Device "Card0" Monitor "Monitor0" DefaultDepth 16 SubSection "Display" Viewport 0 0 Depth 16 Modes "1024x768" EndSubSection EndSection I can't guarantee those were the only important changes I made - I tried a few things in my attempts to create a valid xorg.conf file. But I'm pretty sure that the screen section was the important part.

• Synchronize folder on network, preserving hard links

  - by Waleed Hamra

  I have few computers using Windows XP Pro. I want to synchronize/back a folder from one machine, to another one. This far, It's a simple problem, and I've used FreeFileSync for such operations, with very satisfactory results. But, this all changes when hard links come into play. Today's folder contains lots of hard links, using such backup programs will result in hard links being treated as multiple files, and copied as such, greatly increasing folder size on destination, and defeating the purpose of using all these hard links in the first place. It gets more complicated when we take into consideration the fact that network shares on Windows DON'T expose hard linking facilities, meaning that running a hard-link-aware tool like rsync using --hard-links will be of no use. So my question, how can i backup my folder to the other computer, while preserving hard links? I don't mind installing 3rd party tools to do it, as obviously, the standard windows shares approach won't work... I am guessing there might be some tool that can be installed on both machines and works in a server/client mode? anyone has any idea how to do this?

• Javascript loading never completes on many sites

  - by Joe

  I recently moved country and have found that on many websites the page never finishes loading. In some cases, no content is ever displayed, but the loading will never time out. Loading Developer Tools in Chrome shows me that it is the Javascript files which never load. For example, this BBC article will never load compatability.js, though will load all the other JS files perfectly. Google Maps often fails to finish loading, meaning it's impossible to make searches. There seems to be no pattern to which files will fail to load (i.e. they don't come from the same CDN). I have tried Chrome, Safari and Firefox on OSX 10.8, and Chrome on my girlfriend's OSX 10.7. I have similar issues on the iPad. In many cases, if I can go to the mobile version of the page that seems to load fine. I have run the browsers in private mode, disabled plugins, updated flash, cleared the cache, flushed the DNS cache - though it would seem that if this is happening on other devices, none of this would work anyway. Is this an ISP issue? And if so, why would it be limited to certain JS files and not all? JS files from the same domain work fine, so I'm not really sure what I should be looking for.

• Use external display from boot on Samsung laptop

  - by OhMrBigshot

  I have a Samsung RV511 laptop, and recently my screen broke. I connected an external screen and it works fine, but only after Windows starts. I want to be able to use the external screen right from boot, in order to set the BIOS to boot from DVD, and to then install a different OS and also format the hard drive. Right now I can only use the screen when Windows loads. What I've tried: I've tried opening up the laptop and disconnecting the display to make it only find the external and use the VGA as default -- didn't work. I've tried using the Fn+key combo in BIOS to connect external display - nothing I've been looking around for ways to change boot sequence without entering BIOS, but it doesn't look like it's possible. Possible solutions? A way to change boot sequence without entering BIOS? Someone with the same brand/similar model to help me blindly keystroke the correct arrows/F5/F6 buttons while in BIOS mode to change boot sequence? A way to force the external display to work from boot, through modifying the internal connections (I have no problem taking the laptop apart if needed, please no soldering though), through BIOS or program? Also, if I change boot sequence without accessing external screen, would the Ubuntu 12.1 installation sequence attempt to use the external screen or would I only be able to use it after Linux is installed and running? I'd really appreciate help, I can't afford to fix the screen for a few months from now, and I'd really like to make my computer come back to decent performance! Thanks in advance!

• NAT via iptables and virtual interface

  - by Alex

  I'm trying to implement the following scenario: One VM-host, multiple guest VMs, each one gets its own IP-address (and domain). Our server has only one physical interface, so the intended use is to add virtual interfaces on eth0. To complicate our situation the provider uses port-security on their switches, so I can't run the guest interfaces in bridged mode, because then the switch detects a "spoofed" MAC-address and kills the interface (permanently, forcing me to call the support, which I'm sure will get them a little bit angry the third time ;) ). My first guess was to use iptables and NAT to forward all packages from one virtual interface to another one, but iptables doesn't seem to like virtual interfaces (at least I can't get it to work properly). So my second guess is to use the source IP of the packages to the public interface. Let's assume libvirt creates a virbr0-network with 192.168.100.0/24 and the guest uses 192.168.100.2 as IP-address. This is what I tried to use: iptables -t nat -I PREROUTING --src public_ip_on_eth0:0 -p tcp --dport 80 -j DNAT --to-destination 192.168.100.2:80 That doesn't give me the intended results either (accessing the server times out). Is there a way to do what I'm trying to do, or even to route all traffic to a certain IP on a virtual interface to the VM's device?

• Changing the View of a Folder When It Is Opened from Finder

  - by user60044

  When I was running OS 10.4 I had all my folders beautifully organized with position and which ones should be opened in View mode and which one in Icon, etc. When I transitioned to 10.6 I found that OS ignored all that information and imposes an awful consequence of changing the view for some folder and that view moving up to all parent folders which don't have their views locked. The only way I can think of to get this functionality back is to either write a program that given a root directory will enumerate it setting the views based upon a static template I have. The other way I thought I could accomplish this is by Folder Actions. Aside from the fact that I don't know AppleScript it seems folder actions cannot be inherited. Since I have 1000s of folders involved here, all being inherited from a single root, I could not possibly manually add that action to each of those folders. What I would like to have is a folder action that whenever I open the folder from Finder, then if it contains any JPG, GIF, etc. type image files that it will automatically open that folder with a view of Icon with a reasonable size to support the number of images. If the folder contains only folders, then to open that folder in the list view. Does anyone have anything that could do this for me? Thank You, -- Mark

• HAProxy, health checking multiple servers with different host names

  I need to load balance between multiple running servers with different host names. I cannot set-up the same virtual host on each one. Is it possible to have only one listen configuration with multiple server and make the Health Checks apply the http-send-name-header Host directive? I am using HAProxy 1.5. I came up with this working haproxy.cfg, as you can see, I had to set a different hostname for each health check as the health check ignores the http-send-name-header Host. I would have preferred to use variables or other methods and keep things more concise. global log 127.0.0.1 local0 notice maxconn 2000 user haproxy group haproxy defaults log global mode http option httplog option dontlognull retries 3 option redispatch timeout connect 5000 timeout client 10000 timeout server 10000 stats enable stats uri /haproxy?stats stats refresh 5s balance roundrobin option httpclose listen inbound :80 option httpchk HEAD / HTTP/1.1\r\n server instance1 127.0.0.101 check inter 3000 fall 1 rise 1 server instance2 127.0.0.102 check inter 3000 fall 1 rise 1 listen instance1 127.0.0.101:80 option forwardfor http-send-name-header Host option httpchk HEAD / HTTP/1.1\r\nHost:\ www.example.com server www.example.com www.example.com:80 check inter 5000 fall 3 rise 2 listen instance2 127.0.0.102:80 option forwardfor http-send-name-header Host option httpchk HEAD / HTTP/1.1\r\nHost:\ www.bing.com server www.bing.com www.bing.com:80 check inter 5000 fall 3 rise 2

• Computer loop restarts on Windows loading

  - by Robinson G.

  My computer restarts, just after or during Windows loading (4 squares getting together), or after some time on the desktop IF I'm idle. In order to start the computer I either have to swap my RAM (24Go) in differents DIMM slots, for example (I have 4 slots) : 1-2-4 or 2-3-4 or 1-3-4, not the same position each boot or it restarts in a loop... I can also change the ram timing from 1.5 to 1.6V and it starts, at the next reboot I have to change it again to 1.5 or it won't boot... And If after all, I succeed to boot, I have to use the computer for about 10 minutes, and it's ok, if I don't, it restarts by itself after some minutes. If I stay on the BIOS, It's all OK, I can stay for a whole year without restarting. I have check my RAM on Memtest (4*8G SDRAM DDR3) : OK I have check without graphic card : Still the same. I tried to reset the bios stack by getting it off and on : Still the same. I tried to reset my BIOS, and many settings about the RAM in the menu : Still the same. CPU temps are just fine (around 35°C) I was thinking ofc about the motherboard but I want to be sure. Motherboard : MSI zh77a-g43 RAM : 4*8G Dual Mode or not (depends on the number I put ofc.) PSU : 600W (enough to run all the config) CPU : i7 3770 non K

• Ubuntu 13.10 - How to disable LVM and cryptsetup? cryptsetup: evms_activate is not available

  - by NeverEndingQueue

  I am trying to remove whole drive encryption from my Ubuntu installation. I've run Ubuntu from Live CD, mounted crypt partition and copied it to another partition /dev/sda3. sudo cryptsetup luksOpen /dev/sda5 crypt1 sudo dd if=/dev/ubuntu-vg/root of=/dev/sda3 bs=1M After that I've run boot-repair: https://help.ubuntu.com/community/Boot-Repair Added entry to /etc/fstab: UUID=<uuid> / ext4 errors=remount-ro 0 1 Of course I've replaced with blkid result of my /dev/sda3. I've also deleted overlayfs and tmpfs lines from /etc/fstab. (I've just compared it to content of /etc/fstab in non-encrypted Ubuntu installation and could not find overlayfs and tmpfs). I've chrooted from LiveCD into my system and rebuilt initramfs: http://blog.leenix.co.uk/2012/07/evmsactivate-is-not-available-on-boot.html I've also removed cryptsetup using apt-get remove. Basically I can easily mount my system partition from Live CD (without setting up the encryption and LVM stuff), but can not boot from it. Instead I see: cryptsetup: evms_activate is not available When I've chosen the Recovery mode I've seen this: Begin: Mounting root file system ... Begin: Running /script/local-top ... Reading all physical volumes. This may take a while ... No volume groups found cryptsetup: evms_activate is not available Begin: Waiting for encrytpted source device ... My /etc/crypttab is empty. I am pretty sure that system tries to find encrypted partition, search for LVMs etc. Do you have ideas what could be the problem or how can I fix it? Thanks

• How to define nodes from a Hiera file in Puppet?

  - by Pigueiras

  I am using puppet and the puppet network device management module and I am trying to build my custom type. In the built-in type for the routers configuration, you can specify a list of nodes and then the configuration inside that node: node "c2950.domain.com" { Interface { duplex => auto, speed => auto } interface { "FastEthernet 0/1": description => "--> to end-user workstation", mode => access, native_vlan => 1000 # [...] More configuration } What I am trying to do, is to move the manifest declaration of the nodes and the configuration of my custom type to a Hiera file like this one: nodes: - node1 - node2 config_device: node1: custom_parameter: "whatever1" node2: custom_parameter: "whatever2" And then in the manifest iterate over the hiera file creating the nodes with the configuration of each node with something like (I am taking as reference this question in serverfault): class my_class { $nodes = hiera_array('nodes') define hash_extract() { $conf_hash = hiera_hash("config_device") $custom_paramter = $conf_hash[$name] ## TRICK lies in $name variable node $name { my_custom_device { $name: custom_parameter => $device_conf['custom_parameter'] } } } hash_extract{$pdu_names: } } } But for this solution I have two problems, I can not define a node inside a define and I can not parameterize a node name. So, is there any way to declare nodes from a Hiera file with their configuration inside?
