• PC will be turned off in safe mode

  - by abbasi

  I wanted to scan a Dell inspiron N5010 laptop in safe mode. When I took it to the safe mode environment and ran the AV to scan, after some while the PC went out! The power options menu options (when plug is in) are as follows: Screensaver after 4 mins. Dim to display after 10 mins. Turn off display after 15 mins. Hard disk, sleep and hibernate are all off (set to never). I tested the machine without scanning it, i.e, went to the safe mode and waited to see what occurs after time elapsing. By observations so far (because I can apply more tests to determine that where the problem exactly is), the problem is when the machine is in safe mode and is doing something (in current case, scanning). What do you think? Why it goes out in this situation please? Thanks in advance.

• Application to store/browse/view photos?

  - by amorfis

  I am looking for application which I can install on Ubuntu server and put my photos there. It can be by web interface, it can be by mounted samba disk. What I require: Ability to add tags to photos. Ability to move photos. I.e. if I set photos directory to /home/photos, but then I want to move all photos to e.g. /home/common/photos - I don't want to lose all the tags. I used to use FSpot and it was great, but it lacked point 2, and I lost everything :(

• HTC Android Fails to mount- Mount from computer?

  - by Ben Franchuk

  I Have an HTC Incredible S (S-Off, Rooted, ViperVIVO 1.3.0 ICS) that has seemingly ceased to posses the ability to mount its SD Storage to my computer. For whatever reason, whenever I plug in my device to transfer files from computer to phone and vice versa, the computer, for some reason, cannot actually aces the phone. I get prompted with a window on my phone when I first plug it in, asking me which mode I want to put the device into (Charge mode, tether mode, etc.), and even if I select the "Disk Drive" function, the phone still cannot successfully mount to my computer. The phone itself unmounts itself from the SD and says that the computer is connected, but again, it doesn't work. Is there any way to force mount the device from my computer- either via command or otherwise? This should help in that if I unmount the SD from the phone I should be able to mount it to my computer, from my computer, Correct?

• Difference between VMWare tools?

  - by tore-

  I'm currently writing a module for puppet which installs VMWare tools to virtual nodes. I want to do this via yum and and yum-repo. VMWare have their own repo (http://packages.vmware.com/tools/esx/3.5latest/rhel5/x86_64/index.html) which I thought I could use, rather than creating my own. But then I noticed that their repo files is alot different than the rpm file used when installing VMWare Tools on the node, via the "Install/upgrade VMWare Tools" in vSphere. Does anyone know what the real difference is? Does anyone have any preferences?

• Connecting OS X MacBook Pro to DirecTV DVR

  - by user14293

  I have a DirecTV DVR which soon will be replaced. The local phone carrier has wired fiber-to-the-door and that DirecTV sat service will soon be history. I have irreplaceable video recordings on the DVR's disk I would like to salvage. I'd like to connect my MacBook Pro (OS X 10.5.3) to the DVR (male HDMI to male Thunderbolt) and treat the MAC as a TV monitor. I'd like to capture the video stream to a file and then burn it to DVD. This is for my use only, not for distribution. Still researching video capture. Don't yet have a solution. Maybe there isn't one. Any ideas?

• Dell V105 printer and OS X 10.6

  - by James

  I am trying to get a Dell V105 printer to work with my iMac. It is running 10.6 and I have installed all the drivers on the Snow Leopard disk. I believe there is no official Dell driver but I have also heard the Dell printers are made by third parties that may sell the same printer under different names. There a quite a few Lexmark models that seem to look very similar and I have tried setting the driver to the 2600 series that looks very similar but that has not enabled me to print. Although it claims to give me the supply levels correctly. Can anyone help? Thanks for your time

• IPTables masquerading with one NIC

  - by Tuinslak

  Hi, I am running an OpenVPN server with only one NIC. This is my current layout: public.ip > Cisco firewall > lan.ip > OpenVPN server lan.ip = 192.168.22.70 The Cisco firewall forwards the requests to the oVPN server, thus so far everything works and clients are able to connect. However, all clients connected should be able to access 3 networks: lan1: 192.168.200.0 (vpn lan) > tun0 lan2: 192.168.110.0 (office lan) > eth1 (gw 192.168.22.1) lan3: 192.168.22.0 (server lan) > eth1 (broadcast network) So tun0 is mapped to eth1. Iptables output: # iptables-save # Generated by iptables-save v1.4.2 on Wed Feb 16 14:14:20 2011 *filter :INPUT ACCEPT [327:26098] :FORWARD DROP [305:31700] :OUTPUT ACCEPT [291:27378] -A INPUT -i lo -j ACCEPT -A INPUT -i tun0 -j ACCEPT -A INPUT -i ! tun0 -p udp -m udp --dport 67 -j REJECT --reject-with icmp-port-unreachable -A INPUT -i ! tun0 -p udp -m udp --dport 53 -j REJECT --reject-with icmp-port-unreachable -A FORWARD -d 192.168.200.0/24 -i tun0 -j DROP -A FORWARD -s 192.168.200.0/24 -i tun0 -j ACCEPT -A FORWARD -d 192.168.200.0/24 -i eth1 -j ACCEPT COMMIT # Completed on Wed Feb 16 14:14:20 2011 # Generated by iptables-save v1.4.2 on Wed Feb 16 14:14:20 2011 *nat :PREROUTING ACCEPT [302:26000] :POSTROUTING ACCEPT [3:377] :OUTPUT ACCEPT [49:3885] -A POSTROUTING -o eth1 -j MASQUERADE COMMIT # Completed on Wed Feb 16 14:14:20 2011 Yet, clients are unable to ping any ip (including 192.168.200.1, which is the oVPN's IP) When the machine was directly connected to the internet, with 2 NICs, it was quite simply solved with masquerading and adding static routes in the oVPN client's config. However, as masquerading won't accept virtual interfaces (eth0:0, etc) I am unable to get masquerading to work again (and I'm not even sure whether I need virtual interfaces). Thanks.

• Sharing external storage between different operating systems?

  - by CT

  I just received a Lacie 1TB external usb/firewire/esata drive. I have 2 machines. A macbook running osx 10.6 and a desktop running windows 7. I would like to rip my dvd collection to iso and store on my external. Right now I use my macbook's disk utility to rip dvds to iso. However my desktop is what is connected to my hdtv. I mainly just use the desktop for media. I'd like to format the external with a 200 GB partition for time machine backups and have the rest for storage. DVD iso are often above 8GB so that sort of eliminates FAT file systems correct? Do I have any options to be able to have my mac and pc both see the drive?

• Remotely connecting to a Hyper-V hosted VM's console.

  - by billpg

  Hi everyone. I've just managed to successfully move an aging beige box into a Hyper-V virtual machine. We used to use the beige box by walking over and sitting at the computer itself, but we can't do that so easily when its inside the Hyper-V system. Is there a way please to access the VM's console from a workstation running XP Pro? Please note that its an obscure OS running inside the VM, so installing a VNC or similar service inside the VM is not an option. Many thanks.

• Can we increase Torrent share ratio using Local Peer Discovery?

  - by Jagira

  I just want to know whether this is a flaw or not in Bittorrent system. Let us assume that I am member of a Private Torrent site which requires me to maintain a specific upload to download ratio. Will this work: I create a torrent of a large file say [ Fedora Linux ~ 4 GB ] and upload it to the tracker I download the same torrent using my ID and start it on another machine on LAN or a Virtual machine Both clients have Local Peer Discovery enabled, so they will find 'em [ not via DHT ] and start x'ferring data using LAN bandwidth at LAN speeds. Though both uploads and downloads will increase, my ratio will also increase If I reiterate the entire process 'n' times, the numerator in the "RATIO" i.e Upload will become so large that the effect of downloads on ratio will become less. I want to know whether this is legitimate???

• How to fix White Screen of Death after updating iTunes?

  - by cust0s

  The other night I updated my iTunes to the latest version (through Software Update) when I came to turn on my computer I was greeted with the dreaded white screen of death. I use an early 2008 iMac 24". I've tried the basic things, unplugging/turning off accessories, trying to boot from the install disk, reseting pram, etc, etc. Still no luck and no change what-so-ever. All I've been able to ascertain that my keyboard still works (by ejecting). I should point out that I did recently replace my Hard drive with a Western Digital Black 500GB (though the computer is well out of warrenty) and I'm a little concerned that the problem could be the screen.

• Monitoring remote laptops

  - by kaerast

  We're looking for something to monitor around 30 remote laptops that are constantly out on the road, never returning to base except for when there are serious hardware faults that need repairing. These laptops won't always be connected to the internet, they'll have mobile broadband and may work offline most of the time. They will be running a mixture of Windows XP, Vista and 7 and there is currently no server setup. We're primarily interested in making sure that Windows Updates and antivirus updates are happening, and I guess we should also be monitoring remaining disk space, what software is installed and ideally hardware health. It might also be nice if we could gain remote access to perform work on them. My main reason for wanting to monitor them is that it's going to be a real pain to get them back to base if anything goes wrong, so I want to be proactive in ensuring they last as long as possible. Can you recommend what I should be monitoring to ensure a long life? What tools would you use to monitor and maintain these computers?

• Making GRUB see RAID 0 under Ubuntu 10.10 LiveCD

  - by unknownthreat

  I just installed Windows 7 recently, and I expect that it would alter GRUB and it did. I've been following some guides around and I am always stuck at GRUB not able to detect the usual RAID content. I've tried running: sudo grub > root (hd0,0) GRUB complains it couldn't find my hard disk. So I tried: find (hd0,0) And it complains that it couldn't find anything. So I tried: find /boot/grub/stage1 It said "file not found". So what now? How can we make GRUB see RAID 0 under Ubuntu 10.10 LiveCD?

• Redirect an Apache2 SSL VirtualHost with mod_alias

  - by Jeff

  I want to make sure there aren't any odd behaviors that I don't know about when redirecting a SSL VirtualHost with mod_alias Redirect as outlined by Apache here. My code seems to work, but since SSL virtual hosts are restricted to just one IP address, I want to make sure there aren't any problems eluding me. Explicitly not using TLS. I'm stuck with Apache 2.2 for now. <VirtualHost *:443> ServerName example.com SSLEngine On Redirect 301 / https://www.example.com/ </VirtualHost> <VirtualHost *:443> ServerName www.example.com SSLEngine On # Do stuff # </VirtualHost> So I guess my question is, should SSL VirtualHost redirection with mod_alias Redirect work the same as non-SSL redirection?

• Intel cpu hyperthreading on or off for ibm db2?

  - by rtorti19

  Has anyone ever done any database performance comparisons with hyper-threading enabled vs disabled? We are running ibm db2 and I'm curious if anyone has an recommendations for enabling hyper-threading or not. With hyper-threading enabled it makes it quite difficult to do capacity planning for cpu usage. For example. "With 8 physical cores represented as 16 "threads" on the OS and a cpu-bound workload, does that mean when your cpu usage hit's 50% you are actually running at 100%." What real benefits do I gain with leaving hyper-threading enabled on an intel server running DB2? Does hyper-threading help if you're workload is truly disk IO bound? If so, up to what percentage? These are the types of questions I'm trying to answer. Any thoughts?

• Test/Dummy SMTP server for Windows

  - by geoaxis

  I would like to install a Test/Dummy SMTP server on a Windows 2008 server (virtual box). I just want to test my web application on the machine it self so I don't need the mails to go out on the internet, but just to be written to disk (so that I can verify that the mail function was indeed called and the correct data was handed over to SMTP) Can you recommend some tool. I guess starting your own SMTP server in python is an option. I am looking for a simple (ready to use) solution, targeted for tests systems. I will need to integrate it to automated tests (Selenium) at a later stage. Thanks

• WSUS setup on ADS Domain Controller VM

  - by NickC

  How should I setup sharing/directory permissions to allow the following to work: VMHost - Hyper-V partition (not part of domain) ADServer - Active Directory Domain Controller running as guest VM on VMHost \VMHost\Updates disk share for WSUS to put the updates and other local files Problem is what permissions do I need to give to \VMHost\Updates to allow WSUS to work with this directory to avoid "The WSUS content directory is not accessible" error which I am currently seeing. As far as I can tell WSUS runs as "domain/Network Service" account. Question is without adding VMHost to the domain how do I give that user appropriate permissions to this directory? Is there a way that VMHost can be told to trust ADServer and then be able to use users accounts from there? Sort of relates to my other post here: Win 2012 Domain controller VM, should the Hyper-V host be part of the domain? Thanks, Nick

• Fixing mac user file permissions, not the system

  - by Cawas

  Usually those files get wrong permission when coming from the network, even when I copy them from it, but mostly through "file sharing". So, definitely not talking about Disk Utility repair here, please. But regardless of how the file got wrong permission, I know of two bad ways to fix them. One is CMD+I and the other is chown / chmod. The command line isn't all bad but isn't practical either. Some times it's just 1 file I need to repair, sometimes it's a bunch of them. By "repair" I mean 644 for files, 755 for folders, and current user:group for all of them. Isn't there any app / script / automator out there to do that?

• Deep freeze alternative for Ubuntu

  I made some research and found out that Deep freeze is not available for ubuntu. Is there a software like deep freeze for Ubuntu 10.04. To prevent writing data on the disk. I need this so that I could try all sorts of stuff on Ubuntu without worrying if I could damage the Windows installation that is installed along side with it. Virtual box is good. But the performance is not. Because I only have 2gb of ram.

• Monitoring over Time with Nagios: How?

  - by David

  Nagios in its standard usage monitors with point-in-time checks: either something is - or is not - true. Other tools like SGI's PCP, HP's MeasureWare, and SEC provide monitoring over time - monitoring things like average disk access time over the last five minutes, or other similar items. Is there anything like this for Nagios? I'm already running NDOUtils, which seems like a natural source for such data. I'd like to have something that would monitor and fire off alarms based on a time-based check using historical data. Is there anything like this for Nagios?

• Running Multiple Instances of Firefox

  - by Aaron Bush

  I am running SysInternal's Desktops 1.02 and FireFox 3.6.2. I have noticed that while I can have IE8 open in multiple Virtual Desktops, you can not Firefox. If you try you get the error message: Firefox is already running, but is not responding. To open a new window, you must close the existing FireFox process, or restart your system. I did a little digging around to work around this and came up with creating a second profile via the Firefox profile manager (accessed by starting FF with the "-p" switch). This unfortunately created a new problem which is my add-ons (of which I use many) do not stay synchronized between profiles. Is there a better approach here?

• Tools to monitor guest OS performance in vSphere

  - by Quick Joe Smith

  I am looking for some tool or way to retrieve performance data from guest VMs running under vSphere 4.1. I am currently interested in the 4 basic metrics: CPU(%), Memory(%), Disk availability(%) & Network utilisation(Kb/s). The issue I have is that all of vSphere's performance data is from a ESXi host perspective (active, shared, consumed, overhead, swapped etc.) which is far removed from the data from the VM's own perspective. For instance, I have a Windows server VM idling, using around 410MB (~25% of its allocated 2GB) as reported by Task Manager, and this is the value I'm after. vSphere's metrics seem unable to arrive at this figure by any reliable and repeatable means. Is anyone aware of tools that can obtain this kind of data? The simpler, the better.

• Running PHP scripts as the owner of the PHP file: security issues

  - by thomasrutter

  I'm using suexec to ensure that PHP scripts (and other CGI/FastCGI apps) are run as the account holder associated with the relevant virtual host. This allows for securing each users' scripts from reading/writing by other users. However, it occurs to me that this opens up a different security hole. Previously, the web server ran as an unprivileged user, with read-only access to user's files (unless the user changed the file permissions for some reason). Now, the web user can also write to user's files. So while I've prevented different users taking advantage of each other's scripts, I've made it so that in the event that some application has a remote code injection vulnerability, it now has not only read access but also write access to all that user's scripts and website. How can I deal with this? One idea I've had is to create a second user account for each user account in the system, so that each user has their own user account, and all their scripts are run under another user account. But that seems cumbersome.

• What could explain my partitions disappearing on a new SSD with Windows 7?

  - by charlesrandall

  So this morning, I had a fresh install of Windows 7 pro, on a new SSD (Patriot TorqX 128gb), which I just put in to a new Dell Studio XPS 9000. Everything was fine. I booted to windows, no problem. I go to work. 8 hours later, I come home, and I'm greeted by my boot screen complaining about no bootable devices. Windows repair from the Windows 7 pro disk says it can't fix the problem. It doesn't see any windows installs. I boot up GParted, and my SSD is completely unallocated. No space used, no partitions. Perhaps this is related to allowing windows 7 to create a utility partition when I installed? Only thing I can think of. Is there some kind of known hardware issue that can result in an SSD completely wiping itself?
