• HD Tune warning for "Reallocated Event Count" with a new/unused drive. How serious is that?

  - by Developer Art

  I've just looked at the health status of my old 2,5 inch 500 Gb Fujitsu drive with a popular "HD Tune" utility. It shows a warning for the "Reallocated Event Count" property. How serious is that? The thing is that the drive is practically new. I pulled it out of a new laptop over a year ago and never used it since. Right now it only has 53 "Power On" hours which sounds about right since I only had it running a few evenings overnight before switching it for something more performant. Does this warning indicate that the drive is likely to fail some time in the future? I'm somewhat perplexed since the drive is effectively unused. What is more, I have arranged with somebody to buy off this drive since I don't really need. It is 12,5 mm thick (with 3 plates) meaning it doesn't fit into an external enclosure which makes it quite useless to me. Can I give away the drive without having it on my conscience or better cancel the deal? In other words, can the drive be used safely for years to come or better throw it away? I'm running a sector test now to see if there are any real problems. Will post the results as soon as they're available.

• Event ID: 861 - The Windows Firewall has detected an application listening for incoming traffic

  - by Chris Marisic

  Firstly, my machines aren't compromised any person suggesting such will be DV'd. The security logs on some of my networks client machines (all Windows Xp Sp3) get filled with these useless error messages. Security Failure Audit Detailed Tracking Event ID: 861 User: NT AUTHORITY\NETWORK SERVICE The Windows Firewall has detected an application listening for incoming traffic. Name: - Path: C:\WINDOWS\system32\svchost.exe Process identifier: 976 User account: NETWORK SERVICE User domain: NT AUTHORITY Service: Yes RPC server: No IP version: IPv4 IP protocol: UDP Port number: 55035 Allowed: No User notified: No It's always on various random ports of UDP so setting up a port exception isn't really an option. It's always from svchost or lsass both of which are running services from DLLs. One of the most offending processes seems to the be DnsCache. I have in my global policy under AT < Network < Network Connection < Widnows Firewall < Domain Profile (I haven't changed any standard profile options do both need configured? To allow remote administration and desktop exceptions and have a custom program exception list that has %SystemRoot%\system32\svchost.exe:*:enabled:svchost (Windows won't allow you to add this exception on a local machine but it let me have it on here in the global policy it just doesn't seem to do anything) %SystemRoot%\system32\lsass.exe:*enabled:lsass (I think this one ended all of my LSASS messages) %SystemRoot%\system32\dnsrslvr.dll:*:enabled:dnscache (I tried adding the dll itself to the exception list, this didn't seem to do anything) Is there really any other options left other than disabling the Windows Firewall entirely, disabling auditing entirely or just changing the event viewer to just auto overwrite when needed? I'd much rather fix the problem and get rid of these entries ever being created instead of just trying to cover up the problem.

• DVD-ROM: Pioneer DVD-115GA not being detected.

  - by Wesley

  Specs to put things in context: AMD Athlon XP 2400+ @ 2.00 GHz / 2 x 512 MB PC-3200 DDR RAM / 160 GB IDE HDD / 128 MB GeForce 6200 AGP / FIC AM37 / Windows XP Pro SP3 So this computer is actually an upgraded EMachines T2482. I found a used DVD-ROM for cheap... the Pioneer DVD-115GA. I originally had a plain DVD Reader (Lite-On XJ-HD166S) which was quite useless. So I basically did a simple swap of the drive and powered up the computer. The drive could open and close, and I put in a DVD and it was spinning, but no detection. Going into the BIOS, the drive was not detected. (The IDE cable connecting the DVD-ROM is connected to the CD-ROM below it and then attached to the secondary IDE port on the motherboard.) So I started all the way up and tried to scan for hardware changes in Computer Management. Still, nothing. I have the software downloaded from the Pioneer site, and that couldn't detect anything. So what else can I try to hopefully get my DVD-ROM recognized by the BIOS? Thanks in advance!

• Debugging UI Problems in IE8 (Was IE8 on Windows 7 Authentication Mess)

  - by alharaka

  UPDATE: I think the real question I need to ask here is: how does a technician debug UI problems with Internet Explorer, and not HTML rendering issues that have pretty good tools? I am aware of the SysInternals tools and others mentioned below, but maybe I am not harnessing their power properly. Someone else in the TechNet forum I mentioned had a similar issue. Again, I have lots of data, I am not sure how to properly interpret it. ORIGINAL POST: So I tried the venerable Technet Forums to solve this isse. In short, the Windows Security dialog has no place to put credentials, rendering pretty much useless. This happens to apply for a whole bunch of our intranet websites, and only a select number of users with a few laptops have this problem. It ends up looking like this. Things I have tried so far: Disabling local Group Policy (not domain connected) Disabling local Security Policy Resetting IE settings A few system restores Re-registering a bunch of IE DLL's and all other steps here Reinstalling IE8 (dism /online /disable-feature /featurename:"internet-explorer-optional-x86, reboot, dism /online /enable-feature /featurename:"internet-explorer-optional-x86, and reboot) And SFC scan, which found nothing Still, nothing. Not only am I fed up, but I have begun to really work with APIExplorer and Procmon as mentioned in the Technet original because I want to know WHAT is happening, not just fix it. Any thoughts?

• Remote Desktop Connection Only Works One Way

  - by advocate

  I can't get my desktop to connect to my laptop through remote desktop connection. Unfortunately I can only get my laptop to connect to my desktop (quite useless). Desktop: Windows 7 Ultimate 64 Bit SP1 Windows firewall is off for all 3 profiles (domain / private / public) Remote desktop connection is installed and set to allow all connections Under running services is: Running Remote Desktop Configuration Running Remote Desktop Services Running Remote Desktop Services UserMode Port Redirector Running Remote Procedure Call (RPC) Stopped Remote Access Auto Connection Manager Stopped Remote Access Connection Manager Stopped Remote Procedure Call (RPC) Locator Stopped Remote Registry Stopped Routing and Remote Access Stopped Windows Remote Management (WS-Management) Laptop: Windows 7 Home Premium 64 Bit SP1 Windows firewall is off for all3 profiles (domain / private / public) Remote desktop connection is installed and set to 'Allow Remote Assistance connections to this computer' Under running services is: Running Remote Procedure Call (RPC) Stopped Remote Access Auto Connection Manager Stopped Remote Access Connection Manager Stopped Remote Desktop Configuration Stopped Remote Desktop Services Stopped Remote Procedure Call (RPC) Locator Stopped Remote Registry Stopped Routing and Remote Access Stopped Windows Remote Management (WS-Management) It should be noted that the Laptop that I'm trying to connect to is an Alienware and might be running some wonky Dell settings. Also, the settings are slightly different for remote desktop connection as it's a Home edition of Windows and not Ultimate like my desktop. Finally, both computers are on the same Homegroup so that RDC can be accessed by one click through the network section of Windows. They're also on the same workgroup, MSHOME, just to see if that helps.

• Advice needed: ADSL and VPN for a small company

  - by Saajid Ismail

  Hi. I need advice on purchasing an ADSL modem/router for a small company. At the moment, we are using the iBurst Wireless service for internet connectivity. I have the iBurst desktop modem, which connects to my Netgear WNR2000 router via ethernet. I am using the Netgear WNR2000 to deploy a wireless network as well. I have also set up a VPN using Windows Server 2003, and enabled the VPN Passthrough settings on the Netgear router. I am able to connect to the office network remotely without difficulty. However the problem that I've read is that the Netgear WNR2000 only supports VPN passthrough for a single session. This is simply not good enough. I need to be able to support at least 3 concurrent VPN connections immediately, and up to 5 in the near future. Now I am cancelling my iBurst Wireless service and have just got my ADSL line installed. I have to purchase an ADSL modem, and now is a good time to think of future proofing my investment. I need a good ADSL modem, that will allow me to support at least 5 concurrent VPN connections, or more, without breaking the bank. My budget is about 150-200 USD. I believe that my current Netgear WNR2000 router will be useless, except maybe to extend my wireless network in the future by a bit. Is there a solution where I can still use my Netgear WNR2000 for WiFi, for e.g., by connecting a cheaper non-WiFi ADSL modem to the Netgear router? If not, then which WiFi-enabled ADSL modem/router that supports at least 5 VPN passthroughs can you recommend? To sum it up, I need an ADSL modem/router that is: ADSL & ADSL2+ compatible has built-in 802.11n 270/300mbps WiFi (if having this feature doesn't push the price up too much) supports at least 5 VPN connections using VPN passthrough EDIT: Answer 2.10 in the following FAQ has me a bit worried - What is VPN/multiple VPN Pass-through?

• ESXi Server with 12 physical cores maxed out with only 8 cores assigned in virtual machines

  - by Sam

  I have an ESXi 5 server running on a 2-processor, 12-core system with hyperthreading enabled. So: 12 physical cores, 24 logical ones. On this server are 4 Windows 7 VMs, each configured for 2 processors, each running VMware Tools. Looking at my stats in vSphere, my "core utilization" is constantly maxed out. Yes, these machines are working hard, but only 8 cores have been allocated. How is this possible? Should I look into reducing the processor count per machine as in this post: VMware ESX server? I checked to ensure that hardware virtualization is enabled in the BIOS of the machine (a DELL R410). I've also started reading up on configuration, but being a newbie there's a lot of material to catch up on. It also seems I should only bother with advanced settings and pools if I'm really pushing the load, and I don't think that I should be pushing it with so few VMs. I suspect that I have some basic, incorrect configuration setting, but it's also possible that I have some giant misconceptions about virtualization. Any pointers? EDIT: Given the responses I've gotten so far, it seems that this is a measurement problem and not a configuration problem, making this less critical. Perhaps the real question is: How does the core utilization of the server reach a higher percentage than all individual cores' core utilization, and given that this possibility makes the metric useless for overall server load, what is the best global metric for measuring CPU load on hyper-threaded systems?

• Recommended setting for using Apache mod_mono with a different user

  - by Korrupzion

  Hello, I'm setting up an ASP.net script in my linux machine using mod_mono. The script spawn procceses of a bin that belongs to another user, but the proccess is spawned by www-data because apache runs with that user, and i need to spawn the proccess with the user that owns the file. I tried setuid bit but it doesn't make any effect. I discovered that if I kill mod-mono-server2.exe and I run it with the user that I need, everything works right, but I want to know the proper way to do this, because after a while apache runs mod-mono-server2.exe as www-data again. Mono-Project webpage says: How can I Run mod-mono-server as a different user? Due to apache's design, there is no straightforward way to start processes from inside of a apache child as a specific user. Apache's SuExec wrapper is targeting CGI and is useless for modules. Mod_mono provides the MonoStartXSP option. You can set it to "False" and start mod-mono-server manually as the specific user. Some tinkering with the Unix socket's permissions might be necessary, unless MonoListenPort is used, which turns on TCP between mod_mono and mod-mono-server. Another (very risky) way: use a setuid 'root' wrapper for the mono executable, inspired by the sources of Apache's SuExec. I want to know how to use the setuid wrapper, because I tried adding the setuid to 'mono' bin and changing the owner to the user that I want, but that made mono crash. Or maybe a way to keep running mono-mod-server2.exe separated from apache without being closed (anyone has a script?) My environment: Debian Lenny 2.6.26-2-amd64 Mono 1.9.1 mod_mono from debian repository Dedicated server (root access and stuff) Using apache vhosts -I use mono for only that script Thanks!

• How do I keep folders synced and backed up between two macs using a Linux NAS (rsync?)

  - by Hultner

  I've got two primary computers, one Mac Pro and one MacBook Pro for when I'm on the go. I've also got a Linux sever which also acts as NAS. Currently I backup the entire computers to an external drive with Time Machine which is rather useless and doesn't sync anything. What I really want to do is to keep my important files synced between both computers and my NAS (which is running RAID 5), that way I'm not backing up easily replaceable systemfiles and I've got all my important files in 3 places where two of them are running raid so at least 5 drives would have to crash at the same time before actual data loss occur. Folders I want to keep synced is basically my photo, documents, development, mamp and work folders and then I want to keep the user library folder backed up but not synced. I'm thinking that I'd have to use rsync but don't know how. Before suggesting Dropbox and similar suggestions I don't want to use them because of several reasons some of them being security (Dropbox obviously proved this), Speed (sometimes I'll sync gigabytes of data and that will be significantly faster locally and probably even through VPN as I have a Gigabit pipe), Space (space on my NAS is cheap and only practically limited by my needs), reliability (even if my internet were to go down I still need to be able to keep my files synced incase I'd need to go somewhere on the fly), price (I already have all the hardware and for the amount of gigabytes and bandwidth I'd need I doubt that there's any free or cheap service). Those are my main reason for wanting to keep it locally. I'm sorry for any spelling or grammatical mistakes that I've might have done. I'm writing this on my smartphone from a shaky train and English isn't my mother tongue. I gratefully appreciate any answers even if only partly solving my problem.

• Server 2003 crashing intermittently, want to transfer function to other DC

  - by user1305332

  I have a Win2003R2 server that is intermittently crashing after some virus were introduced. I'm sure all virus have been cleaned thanks to Malwarebytes (were using McAfee - useless). When it crashes you can't login (local or remote) but can still access files remotely and ping it. After a while even file sharing stops and have to kill power to restart it (no BSOD) I need to either fix it (tried to reinstall SP2 and I tried to reinstall windows in repair mode but the repair option was not available when I booted from installation disks) or move it's functionality to another DC (another 2003R2 server). The server that's crashing is old with SCSI drives while the new server uses SATA drives and faster so it seems like a good idea to just transfer roles and ditch the old box. Finding replacement SCSI drives looks expensive if they ever fail. What would I need to transfer roles. If I just move the 5 FSMO roles and copy over the file shares. Would the new server have enough to run without the old server? Never done something like this, just want some tips. Thanks.

• AMIs in Amazon EC2

  - by Jack of Trades

  I really like the Amazon EC2 environment, and thought I'll spend a bit of time playing around with various types of public (Windows!) AMI servers. But testing has been a bit, well, questionable. Some of my findings: It's very difficult to know what exactly a specific public EC2 image is supposed to be doing. Many images come with little to no information. I can't seem to find the passwords to log onto various windows images. Why are they public if they can't be used!? Lots of images are based on S3, and not EBS backed. This is very annoying, as S3 takes a lot longer to do pretty much anything (stop, image etc.) I am only testing images here, so of-course I don't question the value of S3 for other attributes. The description of what an image does is almost useless and many times confusing. Have others come across these EC2 issues. Again, my interest was to just play around with public images for testing/experimentation/etc, and therefore these issues may not be too relevant for more normal EC2 deployment uses.

• An XKB keyboard map that responds to the left and right shift key individually

  - by mbfisher

  First off, excuse my ignorance of X and XKB; I've been trying to hack together a solution in the hope of being able to achieve what I want without requiring a detailed grasp of it. I'm trying to create an XKB keyboard map on Ubuntu 12.04 that allows me to stipulate which of the two shift keys constitutes the Level2 modifier. Specifically, the 4 key should only produce a $ when the right shift is held, not the left. My reading so far: http://www.charvolant.org/~doug/xkb/html/node5.html http://people.uleth.ca/~daniel.odonnell/Blog/custom-keyboard-in-linuxx11 http://www.x.org/releases/X11R7.5/doc/input/XKB-Enhancing.html Lots of searching! I've attempted to define a custom type, and then refer to it explicitly in a symbols map: /usr/share/X11/xkb/types/mbfisher: default xkb_types "mbfisher" { type "RIGHT_SHIFT" { modifiers = None+Shift_R; map[None] = Level1; map[Shift_R] = Level2; }; } /usr/share/X11/xkb/symbols/mbfisher: default partial alphanumeric_keys xkb_symbols "basic" { name[Group1]= "mbfisher"; key <AE04> { type= "RIGHT_SHIFT", symbols[Group1]= [ 4, dollar ] }; }; I'm then selecting the map with the Ubuntu Keyboard Layout GUI. This obviously disables the alphanumeric keyboard apart from the 4 key, but the dollar sign can still be typed with either shift key. I'm conscious of writing a massive question with lots of useless information so I'll stop here; please ask for anything I've missed out. Any ideas?

• laptop headphone jack problems

  - by Xitcod13

  A while back my headphones mysteriously started making static noise and one of them stopped working completely. At first I thought it was headphones so I bought new ones. Alas that did not solve the problem. The problem must be inside my headphone jack. I did some research online and they suggested unplugging USB devices. Which has a strange effect of changing the static noises to high frequency Morse code noises (it's the aliens). I don't have this problem when i listen to music on speakers. The static is there on headphones whether there is music or not. I own a soldering iron for electronics and I am quite skilled at soldering. I would appreciate any help I can get. My laptop is the HDX 18. It has 2 headphone jacks that act exactly the same. Interesting thing i just noticed is that when i pull out my headphones almost all the way both of them start working but so do the speakers making the headphones kinda useless. Maybe there is a way to turn of the speakers as a temporary solution. I am using vista x64.

• How do I create and conveniently search through Libraries in Windows 8?

  - by mtone

  In Windows 7, I took the habit of putting most of my frequently accessed disk areas as Libraries - there were about a dozen. Typing a word in the Start menu would then give me a summary of matches by Library. For example, searching for "WPF" would tell me that I've got some results in the Books library, in the Coding library and a few other PDFs in the Downloads library, one of which I could then expand to see all results within. In Windows 8, that functionality appears to be gone. The Search function in the Charms Bar lists tons of results by type (Documents, Pictures, et cetera) but not by Library. This is practically useless since Documents contains hundreds of .txt and .cs files, a few of which might be Books or Downloads. The only option I found is to go into Explorer and use the search bar in the Library section. However, there again, all search results are mixed together, and I can't seem to find a way to know which Library each result came from (in the Details view, I didn't find a Library column I could add). So, if I want to know which Library contains stuff about a given topic, I have to search the Libraries one by one. Very inconvenient. Is Microsoft slowly deprecating libraries? Any tips? How else can I search through libraries?

• Is it the address bus size or the data bus size that determines "8-bit , 16-bit ,32-bit ,64-bit " systems?

  - by learner

  My simple understanding is as follows. Memory (RAM) is composed of bits, groups of 8 which form bytes, each of which can be addressed ,and hence byte addressable memory. Address Bus stores the location of a byte of memory. If an address bus is of size 32 bits, that means it can hold upto 232 numbers and it hence can refer upto 232 bytes of memory = 4GB of memory and any memory greater than that is useless. Data bus is used to send the value to be written to/read off the memory. If I have a data bus of size 32 bits, it means a maximum of 4 bytes can be written to/read off the memory at a time. I find no relation between this size and the maximum memory size possible. But I read here that: Even though most systems are byte-addressable, it makes sense for the processor to move as much data around as possible. This is done by the data bus, and the size of the data bus is where the names 8-bit system, 16-bit system, 32-bit system, 64-bit system, etc.. come from. When the data bus is 8 bits wide, it can transfer 8 bits in a single memory operation. When the data bus is 32 bits wide (as is most common at the time of writing), at most, 32 bits can be moved in a single memory operation. This says that the size of the data bus is what gives an OS the name, 8bit, 16bit and so on. What is wrong with my understanding?

• Google Chrome - Issues with download dialogs using BinaryWrite

  - by Mila

  Hello, I have an empty ASP .NET page with the code behind to support downloading of PDF files. The page is called from a link-like web control that has NavigateUrl set to this page. In short, I am using the following for streaming: Response.Buffer = false; Response.ClearHeaders(); Response.ContentType = "application/x-pdf"; Response.AddHeader("Content-Disposition","attachment; filename="MyPDFFile.pdf"); byte[] binary = (dataReaderRemote[DataPDFFieldName]) as byte[]; //dataReaderRemote[DataPDFFieldName] has previously retrieved data if (binary != null) { MemoryStream memoryStream = new MemoryStream(binary); int sizeToWrite = CHUNKSIZE; //CHUNKSIZE=1024 for (int i = 0; i < binary.GetUpperBound(0) - 1; i = i + CHUNKSIZE) { if (!Response.IsClientConnected) return; if (i + CHUNKSIZE >= binary.Length) sizeToWrite = binary.Length - i; byte[] chunk = new byte[sizeToWrite]; memoryStream.Read(chunk, 0, sizeToWrite); Response.BinaryWrite(chunk); Response.Flush(); } } Response.Close(); IE as well as Firefox bring the download prompt window asking you whether you wish to open or save the file, while the user remains on the same page containing the link. However, Google Chrome opens a new blank tab and downloads the file automatically. Is there any way to prevent Chrome from opening the extra blank and therefore useless tab? I am using the Google Chrome version 5.0.375.55 (Official Build 47796) on Windows XP. Thanks in advance! Mila

• How do I apply multiple subnets to a server with one NIC?

  - by Cosban

  I am trying to route multiple IPs through one physical NIC on my dedicated server for use with Proxmox KVM VMs. I have a dedicated server which is currently running Debian 4.4.5-8 with 3 available ip addresses for use, which will be displayed as 176.xxx.xxx.196 (main), 176.xxx.xxx.198 (on same subnet as main) and 5.xxx.xxx.166 (different subnet). I am currently trying to route the third IP address with the dedi for use with a vps that I have set up using proxmox v2.x but am having a really, really hard time doing so. Virtual interfaces binding the additional IP addresses work as expected, ruling out external routing problems. The provider has given the following information for the IP addresses on the main subnet: gateway: 176.xxx.xxx.193 netmask: 255.255.255.224 broadcast: 176.xxx.xxx.223 As well as the following information for the IP address on the second subnet: gateway: 5.xxx.xxx.161 netmask: 255.255.255.248 broadcast: 5.xxx.xxx.167 Everything I've tried with /etc/network/interfaces has either not worked, or has rendered the network completely useless. This is the current state of the file, which has the secondary IP address working on the same subnet as well as IPv6 working, but not the second subnet. # Nativen IPv6 Schnittstelle iface eth0 inet6 manual # Bridge IPv4 Schnittstelle (176.xxx.xxx.193/27) auto vmbr0 iface vmbr0 inet static address 176.xxx.xxx.196 netmask 255.255.255.224 gateway 176.xxx.xxx.193 broadcast 176.xxx.xxx.223 bridge_ports eth0 bridge_stp off bridge_fd 0 bridge_maxwait 0 post-up ip addr add 176.xxx.xxx.198/27 dev vmbr0 auto vmbr1 iface vmbr1 inet static address 5.xxx.xxx.166 netmask 255.255.255.248 gateway 5.xxx.xxx.161 broadcast 5.xxx.xxx.167 bridge_ports eth0 bridge_stp off bridge_fd 0 bridge_maxwait 0 post-up ip addr add 5.xxx.xxx.166/27 dev vmbr1 # Bridge IPv6 Schnittstelle (Reichweite: xxxx:xxxx:xxxx:xxxx:xxxx:xxxx::/64) iface vmbr0 inet6 static address xxxx:xxxx:xxxx:xxxx:xxxx:xxxx netmask 64 up ip -6 route add xxxx:xxxx:xxxx:xxxx:xxxx:xxxx dev vmbr0 down ip -6 route del xxxx:xxxx:xxxx:xxxx:xxxx:xxxx dev vmbr0 up ip -6 route add default via xxxx:xxxx:xxxx:xxxx:xxxx:xxxx dev vmbr0 down ip -6 route del default via xxxx:xxxx:xxxx:xxxx:xxxx:xxxx dev vmbr0

• windows cant "see" camera

  - by user330401

  So I bought a lil emerson camera and I am trying to get it to read the thing on windows 7. The instructions for the camer say when you first hook it up via usb AUTOPLAY will come up and your good to go. Well that worked for me the first time I hooked it up. However the 2nd time, it started trying to install drivers. Since then I can't get it to show up in windows explorer. I have tried disabling and uninstalling everything and trying to start from scratch but its useless, I'm stuck with having to pull the sd card everytime. I really dont like doing this as its a cheap camera, so if I can fix the communication between the devices via usb I would be really happy. As of right now the device installation shows a checked USB COMPOSITE DEVICE and 3 X'd GENERIC IMAGE DEVIC. Can someone please help me get this sorted. PS there are no drivers for this camera, not in the packaging, not available from emerson, and to be honest it shouldn't need any. The only function the camera has when hooked up via USB is charging and access to the DCIM. The charging still works, but the drive just won't load. Any suggestions?

• MsMpEng.exe (Windows Defender?) uses a lot of CPU at startup and runs two instances on a single core

  - by dlamblin

  I'm using Windows XP Professional SP2 on a single core AMD64 processor, and I've got two instances of MsMpEng.exe starting up when I start up and log in. They use 64MB and 32MB of ram and 140MB and 80MB of virtual memory, and fluctuate around 80% CPU usage for about 5 minutes at start up. They are (I read) associated with Windows Defender, but I'm concerned about: There's two of them, everything I read generally has only one reported. They might be scanning each other, and I want that to stop. They might be getting scanned by avgrsx.exe (AVG Free 8) (uses about 16Mb v ram) They might also be scanning moe.exe (assosciated with ms live mesh, which I'm considering getting rid of) Lastly I have Microsoft Security Essentials. I don't know the process name associated there. The main concern of mine (apart from the double instances) is that these are all trying to prioritize scanning each other at once except maybe moe.exe. This might seem legitimate but is likely a useless drain on resources. Have I made a mistake in having all of these installed, or is there a way to inform them not to do whatever they're doing that's taking about 5+ minutes at start up? [I also have Google Desktop, but I'm keeping that.] Comment if none of this makes sense to you.

• Protocol to mount fat32 network filesystem on Linux with ability to lock files ( not advisory locks

  - by nagul

  I have a fat32 filesystem sitting on a NAS storage device (nslu2) that I need to mount on my Ubuntu system. I've tried Samba and NFS mounts, but both don't seem to support proper locking. More specifically, I am unable to save files to the mounted drive through GNUcash, KeepassX etc, which makes the share fairly useless. Is there a protocol that allows me to achieve this ? Note that the NAS storage device is running a linux OS so I can run pretty much any protocol that has a linux implementation. The only option I'm not looking for is to reformat the partition to ext3, which I'm not able to do due to other constraints. Alternatively, has anyone managed proper locking of a fat32 system over the network using Samba ? Or, is advisory locking the best you get with a network-mounted fat32 file system ? I've thought of trying sshfs but I've not found any indication that this will solve my problem. Edit: Okay, maybe I can reformat the drive, but to any file system except ext3. The "unslung" nslu2 doesn't like more than one ext3 drive, and I already have one attached. So any solution that involves reformatting the drive to ntfs, hfs etc is fine, as long as I can mount it on linux and lock files.

• Debian/OVH: How to configure multiple Failover IP on the same Xen (Debian) Virtual Machine?

  - by D.S.

  I have a problem on a Xen virtual machine (running latest Debian), when I try to configure a second failover IP address. OVH reports that my IP is misconfigured and they complaint they receive a massive quantity of ARP packets from this IPs, so they are going to block my IP unless I fix this issue. I suspect there's a routing issue, but I don't know (and can't find any useful info on the provider's website, and their support doesn't provide me a valid solution, just bounce me to their online - useless - guides). My /etc/network/interfaces look like this: # The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 iface eth0 inet static address AAA.AAA.AAA.AAA netmask 255.255.255.255 broadcast AAA.AAA.AAA.AAA post-up route add 000.000.000.254 dev eth0 post-up route add default default gw 000.000.000.254 dev eth0 # Secondary NIC auto eth0:0 iface eth0:0 inet static address BBB.BBB.BBB.BBB netmask 255.255.255.255 broadcast BBB.BBB.BBB.BBB And the routing table is: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 000.000.000.254 0.0.0.0 255.255.255.255 UH 0 0 0 eth0 0.0.0.0 000.000.000.254 0.0.0.0 UG 0 0 0 eth0 In these examples (true IP addresses are replaced by fake ones, guess why :)), 000.000.000.000 is my main server's IP address (dom0), 000.000.000.254 is the default gateway OVH recommends, AAA.AAA.AAA.AAA is the first IP Failover and BBB.BBB.BBB.BBB is the second one. I need both AAA.AAA.AAA.AAA and BBB.BBB.BBB.BBB to be publicly reachable from Internet and point to my domU, and to be able to access Internet from inside the virtual machine (domU). I am using eth0 and eth0:0 because due to OVH support, I have to assign both IPs to the same MAC address and then create a virtual eth0:0 interface for the second IP. Any suggestion? What am I doing wrong? How can I stop OVH complaining about ARP flood? Many thanks in advance, DS

• Disable write-protection on Micro SD

  - by Tim

  My task today is to open up and copy some files to 700 brand new micro SD cards. As I get going on this task I am finding that some of the Micro SD cards are telling me "sorry this drive is write protected" To copy the files I am using a standard SD to micro SD card adapter, and a USB SD card reader / writer. I have ensured that the switch is set to OFF on all of my adapters. As soon as I get a Micro SD that tells me it is write protected I can use the same adapter with another micro SD and it works fine, so I know the problem is not with my adapters. My question is: How can I disable the write protection on a Micro SD card? This eHow article seems to indicate that there is also a physical switch on Micro SD cards. However I have personally never seen a Micro SD with a physical switch, and none of the ones I am using today have said switch. Since these cards are brand new and thus empty are the ones that are telling me they are write protected simply useless? Could this be caused by some sort of defect in the cards?
