• Alternative to SecondCopy?

  - by overtherainbow

  Hello I've been using SecondCopy (7.0.0.146) on XP for a few years now to copy important files from one hard-disk to another. One thing that bothers me is that it is unable to copy some files that are open. I assume Windows provides an API that allows an application to put an exclusive lock on an open file and backup utilities like SecondCopy just can't access them until they are closed. As a result, since I have to close a bunch of files/applications for SecondCopy to complete successfully, I typically don't run SecondCopy regularly like I should... which pretty much beats the whole purpose of backing up data :-/ For those of you using a similar solution to back up your important file onto a second mass storage solution... Can you confirm that an open file can be set off-limit with an exclusive lock, and no backup solution will work with those? If you've tried SecondCopy and other solutions recently and you ended up using another solution, which one did you choose and why? Thank you for any feedback.

• Merging multiple versions of same excel spreadsheet

  - by GrinReaper

  So here's the situation: I have multiple versions of the same spreadsheet-- each one has the exact same row and column labels. The difference between any two given spreadsheets is that data in one spreadsheet shouldn't be in the other (but sometimes it might.) Is there anyway to merge all of them into a "master copy" (or just a blank version) of the spreadsheet? (basically, using the data from various versions of that worksheet to fill out the main one) Copy-pasting is extremely tedious, and doesn't allow me to copy blocks of rows IF the row numbering is non-contiguous. (For example, Rows 1, 2, 3, 6 are in a block, but row 4 and 5 just don't exist.) Ideas? Googling hasn't turned up anything that seemed directly relevant to this problem.

• Get cryptic error when trying to create a snapshot of any of my VMs

  - by Zolt

  I'm using Oracle VM VirtualBox. I have 6 VMs that I've imported. When I click on an individual VM, and then click the camera image (or Ctrl+Shift+S) to take a snapshot, the snapshot process fails and VirtualBox gives the following error: Failed to create a snapshot of the virtual machine vmName. Details: Result Code: VBOX_E_IPRT_ERROR (0x80BB0005) This happens not only for one of my VMs, but all of them, if I try to take a snapshot of each one separately, one at a time. My computer is a Windows 7 machine. I have 200 GB free on my hard drive, and I see no reason why the error should occur. I can import VMs, run them, and clone then without any problems. Can anyone tell me what to do to fix the issue?

• What are the differences between MBR vs GPT vs any other partition scheme?

  - by Safran Ali

  Can anyone tell me what the main differences between i.e. MBR vs GPT or any other partition scheme are? Why would one choose one over the other? I am not an expert but from new release of Mac OS X which includes a feature called Time Machine, which I find highly useful. GPT is the requirement for Mac OS X Lion ... so on this basis I would say that GPT is more useful than MBR. What other partition schemes are there and which one should be used in which situation?

• Two Routers - 1 Port Straight to First Router

  - by apples

  At my house we have two Wifi routers one's connected directly to the modem and the other is plugged in down stairs as a second network(Directly connected to the first router) Is there a way that I could make it so that I have the second router have its own network, but have one or two ports that would act as if they were directly connected to the first router? That way I can port forward to devices on the second router. Here are the information about the routers: Router 1 - Linksys WRT54G Running stock firmware Router 2 - Linksys E900 Running Tomato Firmware So to summarize what I'm asking is how would I have two networks from two routers but be able to connect directly to the first router through one of the ports on the second router. Here's a Visio Drawing of what I would like to look like

• Which driver for "ATI Mobility Radeon HD 3650" in a laptop?

  - by Lasse V. Karlsen

  We have some HP laptops here that comes equipped with a video card that identifies itself as "ATI Mobility Radeon HD 3650", like this one. However, which drivers do we choose? As far as we can tell, HD 3650 is desktop cards, or at least there are no drivers listed for that series with "Mobility" in their name. If I pick the following on the ATI Driver Download page: Graphics Windows Vista 32-bit Edition Mobility Radeon Then the dropdown for the card model contains X300, X600, X700, X800, X1300, X1400, X1600, X1800, 9600, 9700 and 9800 models, but no "HD" nor "36xx series". However, if I change to just "Radeon" for the last selection there, I can find a "Radeon HD 3600 Series" model in the list. Also, if I pick "Windows 7" as the operating system, I can find a "Mobility Radeon HD 3000 series" card, but no 3600. So, which one to pick? The main reason I ask is that they all seem to have some kind of problem installing, so neither seems to be the right one (they all crash with "Catalyst Install Manager has stopped working".)

• Unix users and permissions and how they interact with web files.

  - by Columbo

  Hello, When you issue the command ls in Linux you get this sort of thing: drwxr--r-- 1 fred editors 4096 drafts -rw-r--r-- 1 fred editors 30405 file1.php -r-xr-xr-x 1 fred fred 8460 file2.php I know that the rwxrwxrwx are the read, write and execute permissions for the current user. And I think I know that 'fred' is the user who owns the file. So I assume fred can write to file1 but no one else can. But what is the extra bit 'editors' and what is the difference between file1 and file2 with respect to one having an ownership of 'fred editors' and the other 'fred fred'? Also if a web user connects to one of the files, what is their user name and where is this decided? If the server decided that user connecting from the web was going to be fred, does this mean any web user could write to file1? Any information welcomed, I am resaerching this but just getting confused. Thanks

• Samba networking with a domain-joined computer

  - by MCS

  I have two computers connected to the same linksys router - one running Ubuntu 8.04 and one running Windows 7. The Windows computer is part of a work domain (when connected via VPN). I'm trying to also create a home network so I can access the linux server from Windows. From what I understand, I have to first create a Windows workgroup and then configure Samba on linux to join the Windows network. So in Windows, I went to Control Panel - Network and Internet - HomeGroup and got the following message: There is currently no homegroup on your network. Because this computer also belongs to a domain, you can't create your own homegroup, but can join one created by someone on your network. Can I use Samba to create a homegroup? Is there any other way to create a Windows workgroup? Or am I barking up the wrong tree completely?

• Bash: create anonymous fifo

  - by Adrian Panasiuk

  We all know mkfifo and pipelines. The first one creates a named pipe, thus one has to select a name, most likely with mktemp and later remember to unlink. The other creates an anonymous pipe, no hassle with names and removal, but the ends of the pipe get tied to the commands in the pipeline, it isn't really convenient to somehow get a grip of the file descriptors and use them in the rest of the script. In a compiled program, I would just do ret=pipe(filedes); in Bash there is exec 5<>file so one would expect something like "exec 5<> -" or "pipe <5 >6" -is there something like that in Bash?

• Cloning Windows 7 installation from MBR to GPR drive and make it bootable

  - by Nelluk

  I've seen threads on similar topics - such as this one - but the answers never seem to solve how to make it bootable. I have Win 7 64-bit on a PC installed on a 2tb MBR volume. The motherboard is UEFI compatible. I just installed a secondary internal 3TB drive which will be partitioned as GPT. Is there a relatively easy way to clone my installation over to the new drive and have that drive be bootable? I have used EaseUS Partition Master to clone the C volume to the D volume, but that would not boot and I assume the issue is that one is MBR and one is GPT. Is there a process to do this?

• How do I choose which Ethernet Adapter to bridge in VMPlayer

  - by Catherine MacInnes

  I am running vmplayer 3.1.0 on Ubuntu. The host machine has four ethernet adapters that are configured to run on four different subnets. I need to run four VMs each with a single ethernet adapter bridged onto a specific one of the physical ethernet adapters. Does anyone know how to do this? Am I simply exceeding the capabilities of vmplayer and have to go to one of the other vmware products, if so, which one. Note that I have no need to create additional VMs, these are VMs that are being given to me by companies that want us to develop software for their products.

• Sonicwall NAT Policy Loopback

  - by John

  I have an issue and am pretty perplexed over it. I have a sonicwall and its setup with NAT polices and reflexive nat for an internal web server. That is, only 2 policies, no loopback policy, and the internal clients can access the web server by public ip no problems. Now, on another connection, another sonicwall, i have the exact same setup for another web server, with exact same policies (obviously different IP's) and the internal clients can't access the internal website by its public IP without creating the loopback policy. Maybe on the first one I've overlooked it, but I don't see any loopback what so ever and its working fine. My question is, does anyone know why the first one works like this but the second one needs the loopback policy? Thanks

• How to mirror filesystems with millions of hardlinks?

  - by Thomas Berger

  We have one big problem at the moment: We need to mirror a filesystem for one of our customers. Thats usual not really a problem, but here it is: On this filesystem there is one folder with millions of hardlinks (yes! MILLIONS!). rsync requires more then 4 days to just build the filelist. We use the following rsync options: rsync -Havz --progress serverA:/data/cms /data/ Has anyone a idea how to speed up this rsync, or use alternatives? We could not use dd as the target disk is smaller then the source.

• Mouse for a lefty?

  - by Kyralessa

  As a programmer, I'm fairly particular about my keyboard and mouse. One thing I've only recently noticed is that the mice I tend to prefer don't work well for my five-year-old. He's left-handed, but ends up mousing with his right hand on the computer because (a) that's where the mouse is, and (b) most mice are designed for right-handed people anyway. So, a couple of questions: If you're left-handed and you mouse with your left hand, do you have any recommendations on good mice? If you have a lefty in your household (whether or not it's you), is there an easy way to swap settings between left-handed and right-handed mouse buttons? One way is Control Panel Mouse Check the box on the first tab OK. Do you know of anything faster? Or, better yet, what I'd really like is a way to reverse those settings on only one particular mouse, which would be designated as my son's mouse.

• Winlogon.exe causes C++ runtime error

  - by Evan

  Recently I've become unable to log into my Dell Precision M2400. It uses the Dell Controlpoint login GUI instead of the typical windows one, and has now started giving me a runtime error on winlogon.exe that ends with a c000021a BSOD. I have tried running through safe mode and a restore to the last known good setting with no success. Unfortunately by BIOS password is locked and the one IT guy with the password is on vacation and unreachable until after I leave for a business trip. Is there anyway to bypass the Dell logon screen and get to the default windows one? Thanks.

• LibreOffice Calc SEARCH and FIND functions

  - by TTT

  I am trying to process some data in Calc. One of the steps involve finding if a certain string is part of one of the column. I tried using FIND and SEARCH functions. Both behave in the same way and I am not getting correct results. E.g. Say I have following strings in Column A NY SF LON CAN US and am trying to put following formula in column C =SEARCH("NY",A2) The result is - cell C2 will have 1 (which is correct) but if the same formula is copied to other cells in column C - it gives me "#VALUE!" error and I am unable to find out why ? Any one has any ideas ? Thanks in advance TT

• Determining currently-serving files in IIS 7

  - by Nat Papovich

  serverfault showed me this topic, and I think I want to do the same thing, but in IIS, not Apache. I have a "dashboard" application I'm building and I want it to show what files are currently being served by IIS. They'll mostly all be large files. I believe that the ILogScripting COM Interface would have been one good place to start, but it's not available in IIS 7, and it relies on the underlying IIS logs for its data. And therein, I believe, lies my problem. How do I make IIS put in, essentially, two log entries, one as the request begins, and one when the connection is closed? Also, it looks like IIS doesn't "commit" log entries as they're occuring, in "real-time". There's some kind of delay/batch-job. That will cause a problem for me too. Or do I need to do something in isapi instead?

• Why powershell runs executables in separate window?

  - by Artem Tikhomirov

  On one of my servers (2008 R2) powershell refuses to run executables without extension, so typing cmd (or &cmd) in command prompt results in folowing error message: The term 'cmd' is not recognized as the name of a cmdlet Invoking executable one of the following ways pops out separate window (which executes asynchronously in respect to parent). I've tried that in x86 version of powershell and in x64 one. I've tried -Noprofile argument. PATH seems to be OK. It includes System32 and all. The only way I've managed to execute cmd inline form powershell is opening standard cmd.exe shell, executing powershell.exe from it and executing cmd /c echo test from it. Inception, huh? What should I try next?

• Upgrade the Graphics Card for a Dell Dimension 3100

  - by Pat Foran

  Hi, I have a Dell Dimension 3100 Desktop with a 128MB Graphics Card Integrated into the Mother Board. I need to upgrade this 128MB to at least 256MB or 512MB if the system will support same. I am told by Dell that all I have is a PCIx1 slot and that they do not stock a Graphics Card for this. I was told to shop around at Amazon and ebay etc and I would find one there. I have shopped around for some time now and do not know exactly what I am looking for. There are several PCI Graphics Card out there but which one would be the correct one for a Dell Dimension 3100. Can you help me resolve this problem. If you know of a PCIx1 card that will sort out my problem you might please let me have all the details for to purchase it. Regards, Pat,

• Buying Dual Monitors of different size and resolution

  - by rutherford

  I'm about to go choose a dual monitor setup: 1) Is there any reason why I can't just walk out and buy the two TFT screens I like (a wide screen and a 'portrait' screen) and combine them? Mainly wide screen would be for gaming, and portrait for browsing. I'd want the desktop stretching from one to the other (ie drag pointer, apps from one screen to the other) 2) Also do I need separate gfx cards for each monitor or can one cover both? any performance cost? 3) And can I have separate background images for each, seeing as they'll be different resolutions?

• Creating stereo file from two mono files with sox

  - by haimg

  I'm using sox 14.2.0 on Centos 6.0. I have two mono wav files, left.wav and right.wav. I need to combine them into one stereo.ogg file, with left.wav pan 80% to the left, and right.wav pan 80% to the right. I was unable to come up with the sox options needed for this. How do I do this? This is going to be executed repeatably for many files, so I'd prefer an efficient solution. From what I understand there should be a way to do it in one pass (one invocation of sox).

• Redirecting subsite on same domain to other IIS using HTTPS

  - by Alberto

  I've seen many similar questions (and answers) on this subject, but none seem to be on exactly the same situation I am facing. Which is weird since I don't think it is that special, so forgive me if I haven't searched enough. Anyway. I have two websites which are on two IIS7, one facing WAN and one in the LAN. The WAN facing is already HTTPS-only. I want to add the second website, but on the same HTTPS domain and SSL certificate, so that it becomes a subsite like: https://www.domain.com/subsite How can I do a redirect or rewrite on the first IIS to the second one to make this work? I don't think there is a standard IIS feature that can do this. ISA server is not an option currently. But maybe another extension to IIS exists? Done this numerous times on Apache, and am about to ditch IIS for Apache.

• Cluster failover and strange gratuitous arp behavior

  - by lazerpld

  I am experiencing a strange Windows 2008R2 cluster related issue that is bothering me. I feel that I have come close as to what the issue is, but still don't fully understand what is happening. I have a two node exchange 2007 cluster running on two 2008R2 servers. The exchange cluster application works fine when running on the "primary" cluster node. The problem occurs when failing over the cluster ressource to the secondary node. When failing over the cluster to the "secondary" node, which for instance is on the same subnet as the "primary", the failover initially works ok and the cluster ressource continues to work for a couple of minutes on the new node. Which means that the recieving node does send out a gratuitous arp reply packet that updated the arp tables on the network. But after x amount of time (typically within 5 minutes time) something updates the arp-tables again because all of a sudden the cluster service does not answer to pings. So basically I start a ping to the exchange cluster address when its running on the "primary node". It works just great. I failover the cluster ressource group to the "secondary node" and I only have loss of one ping which is acceptable. The cluster ressource still answers for some time after being failed over and all of a sudden the ping starts timing out. This is telling me that the arp table initially is updated by the secondary node, but then something (which I haven't found out yet) wrongfully updates it again, probably with the primary node's MAC. Why does this happen - has anyone experienced the same problem? The cluster is NOT running NLB and the problem stops immidiately after failing over back to the primary node where there are no problems. Each node is using NIC teaming (intel) with ALB. Each node is on the same subnet and has gateway and so on entered correctly as far as I am concerned. Edit: I was wondering if it could be related to network binding order maybe? Because I have noticed that the only difference I can see from node to node is when showing the local arp table. On the "primary" node the arp table is generated on the cluster address as the source. While on the "secondary" its generated from the nodes own network card. Any input on this? Edit: Ok here is the connection layout. Cluster address: A.B.6.208/25 Exchange application address: A.B.6.212/25 Node A: 3 physical nics. Two teamed using intels teaming with the address A.B.6.210/25 called public The last one used for cluster traffic called private with 10.0.0.138/24 Node B: 3 physical nics. Two teamed using intels teaming with the address A.B.6.211/25 called public The last one used for cluster traffic called private with 10.0.0.139/24 Each node sits in a seperate datacenter connected together. End switches being cisco in DC1 and NEXUS 5000/2000 in DC2. Edit: I have been testing a little more. I have now created an empty application on the same cluster, and given it another ip address on the same subnet as the exchange application. After failing this empty application over, I see the exact same problem occuring. After one or two minutes clients on other subnets cannot ping the virtual ip of the application. But while clients on other subnets cannot, another server from another cluster on the same subnet has no trouble pinging. But if i then make another failover to the original state, then the situation is the opposite. So now clients on same subnet cannot, and on other they can. We have another cluster set up the same way and on the same subnet, with the same intel network cards, the same drivers and same teaming settings. Here we are not seeing this. So its somewhat confusing. Edit: OK done some more research. Removed the NIC teaming of the secondary node, since it didnt work anyway. After some standard problems following that, I finally managed to get it up and running again with the old NIC teaming settings on one single physical network card. Now I am not able to reproduce the problem described above. So it is somehow related to the teaming - maybe some kind of bug? Edit: Did some more failing over without being able to make it fail. So removing the NIC team looks like it was a workaround. Now I tried to reestablish the intel NIC teaming with ALB (as it was before) and i still cannot make it fail. This is annoying due to the fact that now i actually cannot pinpoint the root of the problem. Now it just seems to be some kind of MS/intel hick-up - which is hard to accept because what if the problem reoccurs in 14 days? There is a strange thing that happened though. After recreating the NIC team I was not able to rename the team to "PUBLIC" which the old team was called. So something has not been cleaned up in windows - although the server HAS been restarted! Edit: OK after restablishing the ALB teaming the error came back. So I am now going to do some thorough testing and i will get back with my observations. One thing is for sure. It is related to Intel 82575EB NICS, ALB and Gratuitous Arp.

• Windows XP SP3 TCP/IP No buffer space available

  - by Natalia

  I have the exactly same problem as here: Windows XP TCP/IP No buffer space available On Windows XP Pro, SP3 if one does an experiment where one tries to open TCP/IP sockets in a loop (bascially, listen port 7000, listen port 7001, etc.) After approx 649 open sockets, one will start getting errors: No buffer space available (maximum connections reached?) I've tried to edit the registry as described here http://smallvoid.com/article/winnt-tcpip-max-limit.html I set MaxUserPort = 65534 and MaxFreeTcbs = 2000, but it didn't help. What else can I do? I need 1000 server sockets.
