  • All items in my pen drive had been renamed automatically and cannot open it

    - by pabz
    All the items (both files and folders) inside my pen drive had been renamed to some characters like :]h.¡?.A++ and when I try to open any folder Windows gives this message. The filename,directory name, or volume label syntax is incorrect I was told that it is a problem of the pen drive, not a virus. They say if I format the pendrive then I will be able to use it again normally. But I'm not sure. And I need those files. Does anybody knows a solution?

  • Why would i need extra IP adresses from my web host?

    - by user4524
    I am moving to a new and cheaper host. My old one raised the prices suddenly by a factor 10. Now what I did not like about the old one, was that each time I set up a new website, I had to set up a new account, with the result that I have to pay for a lot of webspace and a lot of bandwith i don't use. Now I am moving over to a new host, who cheaply offers virtual servers. Now I am a n00b when it comes to server tech. I have two questions about this: 1. Could I install all my webistes on this virtual server, provided it is big enough? 2. They offer the possibility of getting more than one IP address, but it costs more. What would be the advantage of this? Would I be able to suffice with one IP address?

  • Problems with Apache Mod_Proxy and Microsoft's ReportViewer's Reserved.ReportViewerWebControl.axd

    - by ActionJack
    I've configured an Apache httpd server (v2.2) as a reverse proxy (with SSL) to a Microsoft IIS website running an ASP.NET application with SQL Server Report Services. The proxy mostly works but Report Viewer reports aren't being proxied, all I get is a square window in Chrome and in IE I get the following error: This page contains both secure and nonsecure items. Do you want to display the non secure items? I click yes then I get the following: Unable to locate control: ReportFrame_ctl0_plchldrMainContent_1_ReportViewer1.

  • What is lightweight lock in distributed shared memory systems?

    - by Kutluhan Metin
    I started reading Tanenbaum's Distributed Systems book a while ago. I read about two phase locking and timestamp reordering in transactions chapter. While having a deeper look from google I heard of lightweight transactions/lightweight transactional memory. But I couldn't find any good explanation and implementation. So what is lightweight memory? What are the benefits of lightweight locks? And how can I implement them?

  • Do 7.2k SATA drives and a hardware raid controller always end with trouble?

    - by xelco52
    I'm reading the FreeNAS userguide and came across the statement: Note that hardware RAID configured as JBOD may still detach disks that do not respond in time; and as such may require TLER/CCTL/ERC-enabled disks to prevent drive dropouts. I'm using a '3Ware 9550SX-8LP RAID Controller' and see quite a few stories of people successfully running raid5 on 7.2k consumer SATA drives without issue. Are detached disks only a theoretical problem, or should I expect this to be a common occurrence?

  • How to wipe free disk space in Linux?

    - by Alex B
    When a file is deleted, its contents may still be left in the filesystem, unless explicitly overwritten with something else. "wipe" can securely erase files, but does not seem to allow erasing free disk space not used by any files. What should I use to achieve this?

  • Preventing users from deleting SQL data

    - by me2011
    We just purchased a program that requires the users to have an account in the MS SQL server, with read/write access to the program's database. My concern is that since these users will now have write access to the database, they could directly connect to the SQL server outside of the program's client and then mess with the data directly in the tables. Is there anyway I can prevent access to the database while still allowing access via the client program?

  • Debian - Problems Unmounting External Hard Drives

    - by user331981
    I recently installed Debian Testing on a new laptop and I just noticed that I am having some issues with unmounting external hard drives. I am using Mate Desktop 1.8.1. With the 1st drive, if I right click on the drive and select “safely remove”: The drive unmounts, spins down, immediately spins back up an remounts. Unable to unmount. With the 2nd drive, if I right click on the drive and select “safely remove”: The drive unmounts but does not spin down. With the 3rd drive, if I right click on the drive and select “safely remove”: The drive unmounts but does not spin down, immediately spins back up but does not remount, and after 20 seconds, it spins down and stays that way. Behavior is the same on both USB 2.0 and USB 3.0 ports. On my last laptop, on which I also used Debian Testing + Mate desktop, the safe removal of drives worked out of the box and I never had an issue with it. The drives would unmount, spin down and stay that way. To remount the drive, one needed to unplug the device and plug it back in. I am unsure how to troubleshoot this issue and I am not sure if it is merely a matter of installing a “missing” package of editing a config file. Thank you in advance.

  • SQL Express 2008 R2 on Amazon EC2 instance: tons of free memory, poor performance

    - by gravyface
    The old SQL Express 2005 was running on a low-end single Xeon CPU Dell server, RAID 5 7200 disks, 2 GB RAM (SBS 2003). I have not done any baseline measurements on the old physical server, but the Web app is used by half a dozen people (maybe 2 concurrently), so I figured "how bad can an Amazon EC2 instance be?". It's pretty horrible: a difference of 8 seconds of load time on one screen. First of all, I'm not a SQL guru, but here's what I've tried: Had a Small Instance, now running a c1.medium (High Cpu Medium) Windows 2008 32-bit R2 EBS-backed instance running IIS 7.5 and SQL Express 2008 R2. No noticeable improvement. Changed Page File from fixed 256 to Automatic. Setup a Striped Mirror from within Disk Management with two attached 1 GB EBS volumes. Moved database and transaction log, left everything else on the boot EBS volume. No noticeable change. Looked at memory, ~1000 MB of physical memory free (1.7 GB total). Changed SQL instance to use a minimum of 1024 RAM; restarted server, no change in memory usage. SQL still only using ~28MB of RAM(!). So I'm thinking: this database is tiny (28MB), why isn't the whole thing cached in RAM? Surely that would speed up performance. The transaction log is 241 MB. Seems kind of large in comparison -- has this not been committed? Is it a cause of performance degradation? I recall something about Recovery Models and log sizes somewhere in my travels, but not positive. Another thing: the old server was running SQL Express 2005. Not sure if that has any impact, but I tried changing the compatibility level from SQL 2000 to 2008, but that had no effect. Anyways, what else can I try here? Seems ridiculous to throw more virtual hardware at this thing. I know I/O is going to be rough on EBS volumes, but surely others are successfully running small .NET/SQL apps on reasonably priced instances?

  • Wait random number of minutes

    - by TiborKaraszi
    Why on earth would you want to do that? you ask. Say you have a job that is scheduled to start at the same time over a number of servers. This might be because you have an SQL Server Master/Target server environment (MSX/TSX) or you quite simply script a job and execute that script on several servers. You probably want to spread the load on your SAN and virtual machine host a bit. This is the exact reason I use this procedure. I frequently use MSX servers and I usually add a job step (executing this...(read more)

  • Make a temp network.

    - by giodamelio
    I have a XAMPP test server running on my Windows Vista laptop. I also have a small wireless router. I would like be able to create a small temp network that could broadcast that network so any other computers connected to the wifi can go to localhost/ or an internal ip address and view my server. The router will not be able to be connected to the internet, but I don't see how that would make a difference Thanks giodamelio

  • Windows 2003 routing by port

    - by vansickle
    I have remote Windows 2003 server with two network interfaces e.g. Cn1 and Cn2. I need that all traffic goes through Cn1 except for one port (for me it's 3389, rdp for administration) that works over Cn2. Currently when I setup all connections work through Cn1, I completely lose connection over Cn2 - and can't connect to server via RDP over Cn2. Now I used static routing based on my ip address (which can changed - so it's bad).

  • Why web application on https stops working after windows update?

    - by Rychu
    On Windows Server 2008 R2 I have several web applications on IIS7. One of these applications has https binding with SSL certificate. However after every windows update this one application stops working. Browser says that server is unavailable. It starts working again when I simply open IIS manager, select that https binding, click edit and without changing anything click OK. Why is this happening?

  • SharePoint 2010 and SQL Server 2008 R2

    - by Enrique Lima
    Recently participated in a conversation that asked about what thoughts were around the advantages of SharePoint 2010 and SQL Server 2008 R2. I guess we can really dive in by exploring a document on TechNet by the name of SQL Server 2008 R2 and SharePoint 2010 Products: Better Together (white paper)

  • Clean Install Windows on a Acer Aspire Laptop with a Hybrid Drive

    - by user1325179
    I'd like to do a clean install of Windows 8 on my Acer Aspire laptop (Aspire M5-481PT) with a hybrid drive. Physically, there seem to be two hard drives (an HDD and an SSD). So when I try to clean install Windows, I am asked to pick a drive. The HDD has five partitions (some seem to be recovery related), and the SSD has two partitions. Which partitions should I delete (if any), and onto which drive should I install Windows 8? And then how can I instruct Windows 8 to use the HDD-SSD combination as a hybrid drive? Edit: Currently, the operating system seems to be installed (from the factory) on the HDD. The SSD is invisible in File Explorer. It is only visible in disk utilities. I'm betting I need to install Windows to the HDD, and then point Windows to use the SSD for the hybrid relationship. Also, the SSD is about 20 GB. The HDD is about 450 GB.

  • How to configure Apache to act as an SSL proxy to an application server?

    - by ripper234
    I have one physical server that runs: an Apache (httpd) server another web server (let's say Tomcat for sake of argument) on port 1234 Can I configure the Apache server to act as a proxy for SSL traffic, while keeping the application server blissfully unaware of SSL? What I imagine is: Traffic to http://myserevr.com/app is redirected to https://myserver.com/app Traffic to https://myserver.com/app is proxied to the application server. My SSL certificate is only installed on the Apache server, not on the Application server Other traffic to the Apache server (http://myserver.com/anotherapp) is served directly from the Apache server What's the best setup to achieve this? (On Ubuntu, if that matters)

  • mysql questions for beginners

    - by ankhseeker
    ok, I have a few questions regarding mysql. I am currently running ubuntu 12.04.4 LTS command line version. I am looking for a database that I can use. I am confused at this point because I am uninformed. mysql is just one database that is on the server? or can it contain several or many databases What programs do I use to access it on the server or is it a vt-100 type access? I understand that mysql comes with lamp? or ubuntu. I am thinking that it is already installed but not sure how to access it, but that is another question for later. Outside of the man pages and the ubuntu manual, is there a site for its setup and use? Thanks!

  • Windows shows incorrect free space on Raid 10 volume

    - by Adenverd
    I have 4 1TB hard drives in RAID 1+0 configuration. Theoretically, I should have ~2TB of available space. Windows says the drive has a total size of 1.81 TB, which I'm fine with. As far as files on the volume go, I used WinDirStat to determine that I have 552.8GB of files on the volume. This means that I should have somewhere around 1.3TB minimum of free space. Yet Windows shows the drive as only having 492GB of free space. Are there hidden files somewhere that I can't see (I have show hidden files/folders turned on)? Does Windows not recognize that old files have been deleted? Is there any way to correct this problem?

  • Avoiding memory full -> swap full -> crash

    - by Noam
    I'm experiencing an issue when sometimes the memory gets 100% full, and the swap file also, and the server becomes non-responsive and has to be restarted (causing also problems in database). This is what Cacti shows: The server is running a web-app (database + apache) and during that specific moment didn't experience any ir-regular traffic or usage. This scenario happened twice in the last week. What can cause this? How can I resolve the issue?
