• Ubuntu 12.04 boot degraded raid

  - by beacon_bonanza

  I've installed Ubuntu 12.04.1 in a new server and set up the 4 hard drives with 3 RAID 1 devices, the configuration is such that the first two drives have md0 (swap space) and md1 (/) with the third and fourth drives having md2 (/var). I've been testing the operation under a drive failure and found that the system boots fine if I remove disk two but if I remove disk one then the system gets to grub and then just restarts. I'm confused as to why grub appears to be loading properly from disk two but then the boot fails. I've tried to copy the MBR from disk 1 to 2: dd if=/dev/sda of=/dev/sdb bs=512 count=1 but this didn't make a difference. Any ideas how to get it to boot from just the second disk? fdisk -l Disk /dev/sda: 2000.4 GB, 2000398934016 bytes 255 heads, 63 sectors/track, 243201 cylinders, total 3907029168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000ccfa5 Device Boot Start End Blocks Id System /dev/sda1 2048 31250431 15624192 fd Linux RAID autodetect /dev/sda2 * 31250432 3907028991 1937889280 fd Linux RAID autodetect Disk /dev/sdb: 2000.4 GB, 2000398934016 bytes 255 heads, 63 sectors/track, 243201 cylinders, total 3907029168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000ccfa5 Device Boot Start End Blocks Id System /dev/sdb1 2048 31250431 15624192 fd Linux RAID autodetect /dev/sdb2 * 31250432 3907028991 1937889280 fd Linux RAID autodetect Disk /dev/sdd: 2000.4 GB, 2000398934016 bytes 255 heads, 63 sectors/track, 243201 cylinders, total 3907029168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00035b05 Device Boot Start End Blocks Id System /dev/sdd1 2048 3907028991 1953513472 fd Linux RAID autodetect Disk /dev/sdc: 2000.4 GB, 2000398934016 bytes 255 heads, 63 sectors/track, 243201 cylinders, total 3907029168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000c73aa Device Boot Start End Blocks Id System /dev/sdc1 2048 3907028991 1953513472 fd Linux RAID autodetect Disk /dev/md1: 1984.3 GB, 1984264208384 bytes 2 heads, 4 sectors/track, 484439504 cylinders, total 3875516032 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/md2: 2000.3 GB, 2000263380992 bytes 2 heads, 4 sectors/track, 488345552 cylinders, total 3906764416 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/md0: 16.0 GB, 15990652928 bytes 2 heads, 4 sectors/track, 3903968 cylinders, total 31231744 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000

• SAS Expanders vs Direct Attached (SAS)?

  - by jemmille

  I have a storage unit with 2 backplanes. One backplane holds 24 disks, one backplane holds 12 disks. Each backplane is independently connected to a SFF-8087 port (4 channel/12Gbit) to the raid card. Here is where my question really comes in. Can or how easily can a backplane be overloaded? All the disks in the machine are WD RE4 WD1003FBYX (black) drives that have average writes at 115MB/sec and average read of 125 MB/sec I know things would vary based on the raid or filesystem we put on top of that but it seems to be that a 24 disk backplane with only one SFF-8087 connector should be able to overload the bus to a point that might actually slow it down? Based on my math, if I had a RAID0 across all 24 disks and asked for a large file, I should, in theory should get 24*115 MB/sec wich translates to 22.08 GBit/sec of total throughput. Either I'm confused or this backplane is horribly designed, at least in a perfomance environment. I'm looking at switching to a model where each drive has it's own channel from the backplane (and new HBA's or raid card). EDIT: more details We have used both pure linux (centos), open solaris, software raid, hardware raid, EXT3/4, ZFS.

• Safer RAID5 rebuilds using partially failed disks?

  - by arcticmac

  There have been lots of articles posted recently about how RAID5 is dangerous because of long resilver times, and in particular because of increasing chances of encountering a URE during the resilver. Obviously this is a significant concern. However, it seems that in many cases of interest (as long as you're keeping some kind of eye on your disks), when it comes time to rebuild the array, the disk that I'm replacing is still mostly readable. If you try to explain this predicament to the average layperson, they are typically very confused as to why you have two almost completely functional disks but can't produce one working array. It seems to me that there ought to be some way to take advantage of this to make rebuilds safer, as long as I'm willing to have the RAID5 be read-only for a couple of days while it rebuilds. Conceptually, what I have in mind looks something like this: When a disk fails, immediately take the RAID5 offline or mount it read-only Attach a new disk (either in a spare bay, or externally via eSATA) and begin rebuilding it to replace the failed one. If known, perhaps start with the stripes in which the failure occurred, to minimize the chances of losing those if another disk fails. In the event that a second disk experiences a URE or other failure during the rebuild, try to source that data from the disk that is being replaced. Presumably if this happens, more rebuilding would be necessary. When complete, shut down the server, swap the replacement drive into the original bay if desired, and bring the array back up. Obviously such a process would not be appropriate for applications where uptime is critical or data loss cannot be tolerated, but it seems to me that this could help considerably to improve the reliability of RAID5. I assume that there's not a good way to implement a recovery like this at present, given that I haven't seen any indication of tools that are designed to do this, and that it seems like it would be rather obtuse to work out manually. Are there also technical issues with it that I haven't thought of (I'm still fairly new to RAID stuff)? Any thoughts on how hard something like this would be to implement (e.g. in linux md raid)?

• Windows 7 laptop constantly dropping internet connection

  - by Corbin Holbert

  I have scoured the web for an answer and failed to find one. I am using a Toshiba Satellite laptop running Windows 7 64-Bit. I have the computer connected via Wifi. Now, I am no beginner with the Internet, or anything related to computers, as I have grown up teaching everyone around me how to use computers, and went to college for IT. Everything on my network works flawlessly at all times, except for this evil laptop. The worst part is that I fixed this once before a few years back and recently had to replace the hard drive and re-install the OS, but cannot for the life of me remember what I did to make this problem go away. I am in my browser, connected to the Internet. I click a link. Suddenly no internet access. All I do is click down on the WiFi connection in the task bar, disconnect and reconnect immediately. Internet is back the moment I hit "connect." I have read many people had the same issues as I am having, but they all had triggers or other network issues. I have no trigger (this happens literally five to six times per minute no matter what I am doing) and I have no problems with my router, modem, or any other devices or computers on said network. As I am a web designer, and like to test my work live at every turn- this is going to result in this laptop being in pieces if I can't get it fixed soon. If more info is needed, let me know and I will provide. Thanks for any help offered! EDIT: Network Card: Realtek RTL8188CE Wireless LAN 802.11n PCI-E NIC Network state reads as "No Internet Access" when the problem first occurs, then magically I have Internet access for about ten seconds once I disconnect and reconnect. I have turned off IPV6, I have turned off power saving options for the network adapter, no viruses. Any new ideas? Also, I had to disconnect and reconnect four times just to get to this edit screen- and will likely have to do the same just to post it- it's that bad.

• Cannot browse network shares in Windows Explorer, but paths are still accessible

  - by Jeff Lockhart

  Windows Explorer has somehow corrupted itself and I'm not sure how to fix this problem. My Windows installation has been in use for a few years with network shares setup and working. Recently, I noticed that a program that I use to save network share paths to a database was no longer opening the explorer window to browse the path. It usually opens to the last path saved, but now it was just not opening at all. When I go to Windows Explorer to browse the network share directly, I get the error \\SERVER is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions. The specified network provider name is invalid. The network shares are just shares on the server itself (once saved to the database, they're used on the server as well as clients to reach files). The strange thing is, the files are still accessible from the program that uses them if I type the network share path in manually. So it is only a problem with Windows Explorer browsing the path. The reason I think there is some sort of configuration or setting, possibly in the registry, corrupted is that when the problem first manifest itself, I was somehow able to open an explorer window to a network share path, but the breadcrumb in the address bar did not function properly. It duplicated the share name folder at the top of the breadcrumb stack and when I clicked the second of the duplicated share folder, it crashed explorer.exe. I haven't been able to browse any network share path since this happened. I have tried using the IP address directly \\192.168.1.# as well as \\localhost and neither of those work either. I have tried running sfc /scannow and it did not find any errors. I tried ipconfig /flushdns and this made no difference. Attempting to map the network share to a drive fails using either the explorer GUI or net use command. Is there some way to reset Windows Explorer somehow to resolve this? I'd really like to avoid reinstalling Windows entirely if I can.

• Are file access times not properly maintained in Mac OS X?

  - by Ether

  I'm trying to determine how file access times are maintained by default in Mac OS X, as I'm trying to diagnose some odd behaviour I'm seeing in a new MBP Unibody (running Snow Leopard, 10.6.2): The symptoms (drilling down to the specific behaviour that seems to be causing the issue): mutt is unable to switch to mailboxes which have recently received new mail mail is delivered by procmail, which updates the mtime of the mbox folder it is updating, but does not alter the atime (this is how new mail detection works: by comparing atime to mtime) however, both the mtime and atime of the mbox file is getting updated Through testing, it does not appear that atimes can be set separately in the filesystem: : [ether@tequila ~]$; touch test : [ether@tequila ~]$; touch -m -t 200801010000 test2 : [ether@tequila ~]$; touch -a -t 200801010000 test3 : [ether@tequila ~]$; ls -l test* -rw------- 1 ether staff 0 Dec 30 11:42 test -rw------- 1 ether staff 0 Jan 1 2008 test2 -rw------- 1 ether staff 0 Dec 30 11:43 test3 : [ether@tequila ~]$; ls -lu test* -rw------- 1 ether staff 0 Dec 30 11:42 test -rw------- 1 ether staff 0 Dec 30 11:43 test2 -rw------- 1 ether staff 0 Dec 30 11:43 test3 The test2 file is created with an old mtime, and the atime is set to now (as it is a new file), which is correct. However, test3 is created with an old atime, but is not set properly on the file. To be sure this is not just behaviour seen with new files, let's modify an old file: : [ether@tequila ~]$; touch -a -t 200801010000 test : [ether@tequila ~]$; ls -l test -rw------- 1 ether staff 0 Dec 30 11:42 test : [ether@tequila ~]$; ls -lu test -rw------- 1 ether staff 0 Dec 30 11:45 test So it would seem that atimes cannot be set explicitly (it is always reset to "now" when either mtime or atime modifications are submitted). Is this something inherent to the filesystem itself, is it something that can be changed, or am I totally crazy and looking in the wrong place? PS. the output of mount is: : [ether@tequila ~]$; mount /dev/disk0s2 on / (hfs, local, journaled) devfs on /dev (devfs, local, nobrowse) map -hosts on /net (autofs, nosuid, automounted, nobrowse) map auto_home on /home (autofs, automounted, nobrowse) ...and Disk Utility says that the drive is of type "Mac OS Extended (Journaled)".

• Is real-time or synchronous replication possible over WAN link?

  - by johnnyb10

  The company I work for is looking to implement truly real-time file replication with file locking over a WAN link that spans over 2000 miles. We currently have a 16-drive SAN setup in our east coast office. We also have an office out in Colorado that will have the same exact SAN setup. The idea is to have those two SANs contain the same exact data at all times, which will allow us to work with the same data pool, and which will also provide use with an offsite backup solution, should a failure occur on either end. We're running Server 2008. The objective is to enable users in the east coast office to work on files and have those changes be instantly updated on the Colorado SAN as well. We also need there to be file locking so that there will be no conflicts or overwritten changes if users attempt to work on the same file. Is this scenario even possible, at speeds that would make the files usable? And if so, what software would we need to pull this off? As I understand it, DFS-R does not provide file locking, so if we used that, we would need to go with a third-party product like Peerlock. But I don't even know if DFS-R is an option. Can it replicate quickly enough over a WAN link? Can any product? It seems that if we were to use synchronous replication, the programs would be unacceptably slow, as every write would have to wait for confirmation from the other end of the link. But if we used asynchronous replication, what kind of latency would we be looking at? There is a product from GlobalScape called WAFS that claims to provide "File coherence with real-time file locking, file release, and synchronization" and says that "As files are modified, changes are mirrored instantly using intelligent byte-level differencing to minimize the impact on network bandwidth". So this sounds like synchronous replication, but that doesn't even seem possible, given physical limitations such as the speed of light. If anyone has any experience with this kind of setup, or knows whether it's even possible, I'd appreciate your input and suggestions, including recommendations for software that we should check out.

• Optimal setup for ASUS P6X58D Premium BIOS (no OC)?

  - by rumtscho

  Normally, I'd trust the mainboard manufacturer to choose the best options as defaults. But I had trouble with the board, because even with Quick Boot enabled, it booted twice as slowly as a Pentium 4 Celeron. Then I changed lots of options at once (most of them weren't explained in the manual, just mentioned with a single sentence) and the boot time is only marginally worse than the Pentium 4 (54 sec against 46 sec from button to pw entering screen). Now I don't know if I have turned something off which should have stayed on. I guess I even won't be able to boot from a CD now, because even though it is present in the boot sequence, I took off a timeout I think it needs to check whether there is a disk in the drive. The second reason is that I don't have an internal HDD, only a SSD. I forgot my sources blush but I am under the impression that today's BIOS and OS options are geared toward booting from a HDD, which is often less than optimal when one boots from a SSD, especially when there are functions which cause avoidable writing cycles, as a SSD wears out after too many writing cycles. Most of the things I've read concern the OS, but there are some BIOS-relevant options too. I am especially confused about the disk mode. The board supports AHCI, IDE-simulation and RAID, but of the different articles I've read, there is a proponent for each and no clear arguments for any. So can one tell me which options are important in general and which are important for a SSD-only system? I don't want to overclock the CPU, so you don't have to say anything about this (yes I know the board is meant for OC:)). I am thinking of overclocking the RAM, since they sold me 1600er heatsinked modules which are running at 1066 now, but I'm not sure yet about that. The rest of the system: i7-930, Intel X25-m G2, 6 GB RAM, GTS 250, some no-name Blue-ray ROM. 2 external HDDs over USB 2.0. Lots of other USB-connected hardware (12 devices I think), no SATA 3 drives (will disabling the controller have an impact on performance?), no LAN, only WiFi. Lucid Lynx 64 bit, no dual boot, no virtual installations. The main uses of the system are: managing and playing/showing all the media stored on the external disks, lots of image manipulation, some video editing, a bit of (non-demanding) gaming, rarely development. Lots of Internet surfing too, but this shouldn't have much impact on performance.

• Some apps very slow to load on Windows 7, copy & paste very slow.

  - by Mike

  Hello, I searched here and couldn't find a similar issue to mine but apologies if I missed it. I've searched the web and no one else seems to be having the same issue either. I'm running Windows 7 Ultimate 64bit on a pretty high spec. machine (well, apart from the graphics): Asus M4A79T Deluxe AMD Phenom II 965 black edition (quad core, 3.4GHz) 8GB Crucial Ballistix DDR 1333MHz RAM 80GB Intex X25 SSD for OS 500GB mechanical drive for data. ATi Radeon HD 4600 series PCI-e Be Quiet! 850W PSU I think those are all the relevant stats, if you need anything else let me know. I've updated chipset, graphics and various other drivers all to no avail, the problem remains. I have also unplugged and replugged every connection internally and cleaned the RAM edge connectors. The problems: Video LAN (VLC) and CDBurnerXP both take ages to load, I'm talking 30 seconds and 1 minute respectively which is really not right. Copy and paste from Open Office spread sheet into Fire Fox, for example, is really, really slow, I'll have pressed control V 5 or 6 times before it actually happens, if I copy and then wait 5 to 10 seconds or so it'll paste first time so it's definitely some sort of time lag. Command and Conquer - Generals: Zero Hour. When playing it'll run perfectly for about 10 or 20 seconds then it'll just pause for 3 or 4 then run for another 10 or 20 seconds and pause again and so on. I had the Task Manager open on my 2nd monitor whilst playing once and I noticed it was using about 25% of the CPU, pretty stable but when the pause came another task didn't shoot up to 100% like others on the web have been reporting (similar but not the same as my issue, often svchost.exe for them) but dropped to 2 or 3% usage then back up to 25% when it started playing properly again. Very odd! But it gets even odder... I had a BSOD and reboot last week, when it rebooted the problem had completely gone, I could play C&C to my heart's content and both the other apps loaded instantly, copy and paste worked instantly too. I did an AVG update earlier this week which required a reboot, rebooted and the problem's back. I don't think it's AVG related though, I think it was just coincidence that's the app that required a reboot. I think any reboot would have brought the issue back. A number of reboots later and it hasn't gone away again. If any one could make any suggestions as to the likely cause and solution to these issues I'd be most grateful, it's driving me nuts! Thanks, Mike....

• Fedora 13 post security update boot problem

  - by Alex

  Hello. About a month ago I installed a security update that had new Kernek 2.6.34.x from 2.6.33.x), this is when the problem occurred for the first time. After the install my computer would not boot at all, black screen without any visible hard drive activity (I gave it good 30 minutes on black screen, before took actions)... I poped in installation DVD and went in rescue mode to change back the boot option to old kernel (was just a guess where the problem was). After restart computer loaded just file, took a long time for it to start because of SELinux targeted policy relabel is required. Relabeling could take very long time depending on file size. I assumed that the update got messed up somehow and continued working with modified boot option. Couple of days ago, there was another kernel update. I installed it and same problem as before. This rules out corrupted update theory... Black screen right after 'BIOS' screen before OS gets loaded. I had to rescue system again... Below is copy of my grub.conf file. I am fairly new to LINUX (couple of years of experience), mostly development and basic config... nothing crazy. # grub.conf generated by anaconda # # Note that you do not have to rerun grub after making changes to this file # NOTICE: You have a /boot partition.

• Kickstart based installation of RHEL 6.4 from USB

  - by Peter

  I want to setup some brand new servers with RHEL 6.4. Servers do not have DVD, so, I have to use USB for the installation. I already have a custom ISO with a kickstart file that I use on servers with DVD flawlessly. I used iso2usb to move the ISO t? my USB.

• Small Business Server services will not start, and remote desktop and UAC are broken

  - by Stephen Jennings

  Yesterday I began setting up a server with Windows Small Business Server 2008. All I am configuring it for right now is to be a domain controller and Exchange server. I completed the initial setup of SBS then started looking through different connection options (allowing VPN versus using a TS Gateway). After I rebooted one time, I started having three not-obviously-related issues: First, I could no longer remote desktop into the computer. I ran TCPView and saw that it was no longer listening on port 3389. I checked everything in Terminal Service Configuration but everything shows the computer ought to be allowing connections. Also, when I tried to use anything that required user account control elevation, the UAC dialog never popped up and the program that was waiting just froze. If I try to run "regedit" from the Run box, for example, it never appears. When I run in safe mode which does not run with UAC, I was able to access everything. I didn't want to deal with it, so I turned off UAC and rebooted. Finally, in the Windows SBS Console, there are status indicators for Security, Updates, Backup, and Other Alerts. The first three get stuck saying "Querying". Looking in the computer alerts, I have events showing the following services stopped: Background Intelligent Transfer Service KtmRm for Distributed Transaction Coordinator Distributed Transaction Coordinator Microsoft Exchange Information Store Microsoft Exchange System Attendant Microsoft Exchange Transport Windows Remote Management Update Services Windows Update I figured I must have configured something wrong accidentally and I couldn't find anything using Google explaining what might be the case, so I just decided to format the hard drive and reinstall SBS from scratch. I did this and everything was working last night, but I just turned the machine back on and it is doing the same thing again! On my second install, I did not configure anything except the following (all from SBS Console): Connect to the Internet (set IP and router address) Turn off customer feedback. Set up internet address. Decline to use a Smart Host for email. Added one standard user account. Since this happened again and I was very careful the second time not to configure anything outside of the SBS Console, I feel like there's something else going on. Right now the machine is on an isolated network that does have internet access. My desktop is the only other machine plugged into this network. Any and all help is appreciated (before I tear my hair out!)

• Having troubles connectiong Magento to external Windows Database Server using Windows Azure

Also, I have tryed to setup mysql on independant Linux Server but kept getting errors. When, I found the solution. Wouldn't work, so I decided to try Windows. These is the questions, I have been asking and researching to debug this issue Is it because I am using Linux for magento and Windows for Database. I have had no luck in finding a reason why this wouldn't work There must be something, I am missing I also researched the difference between linux sql databases and windows sql databases but have not come to conclusion, if installing Mysql on windows would make a difference in syntax and coding. I have spent a lot of time looking into this and need some help with direction on how to complete my project. Any type of help would be appreciated.

• IE and Google Chrome timeout on an IIS6 hosted SSL page that Firefox handles well.

  - by Thomas

  Ok, here's the scenario: Up until a few weeks ago, none of us noticed anything wrong with the corporate website. People were using it without complaint. Then, a client complained that a specific page on the site was timing out for him, and only when he committed a POST action on a form filled with data. I checked it out, and it timed out for me, too. But, it only timed out in Google Chrome and IE, not in Firefox. Additionally, the same page, on the same server, but served from a different domain name (one not under the protection of SSL, either) does not time out under any browser. To clarify: https://www.mysite.com/changes.php times out on POST, but the same with http works fine. That distinction (SSL vs. Non-SSL) seems to be important, as nothing else has changed. Our certificate is valid, and Firefox detects no errors thrown by the page. I've looked at the Request and Response headers from the page, and they all follow the correct formats. Then, after wandering through the site, I noticed a few other things. Both IE and Chrome will frequently time out on any page that is PHP-based. They never time out on static images or html files. I've looked at the site from a variety of different servers, my home and work workstations, and my netbook. Because of that, I've discounted a viral infection, as I highly doubt a virus is going to hit every one of the machines to which I have access in exactly the same manner. My setup is: Server: Win2k3, II6, PHP 5.2.9-1. Clients: IE7, IE8, Chrome (regular and dev channel): Frequent timeouts on PHP pages. Firefox 2, Firefox 3: No timeouts. Firebug shows no errors or even lengthy periods serving the pages. I've spent 2 days searching for any tech knowledge that I can find, and my search parameters are all too general. Everyone has problems loading SSL pages in IE and Chrome for a wide variety of reasons. The infrequent nature of the timeouts and the fact that there are no errors being reported anywhere is starting to drive me insane. Does anyone have any insight on a problem like this?

• Windows 7 file-based backup service

  - by Ben Voigt

  I'm looking for a good replacement for Lazy Mirror, since it doesn't support Windows 7 well. Pros: One of the things I really loved about Lazy Mirror is that it always maintains a "full" backup, but does so by only copying modified files. As each file was copied, the old version got archived (moved to an out-of-the-way location). So after mirroring ran, there'd be a complete copy of the file system, which could even be booted if necessary. At the same time, extra space on the backup media was used to store as many older versions of files as possible, without wasting space storing multiple copies of the same version. It seems that with Windows 7 backup, there'd be wasted space storing the same data in both the system image and file backup. It was completely file-based, but also aware of the registry (it had a feature to dump the live registry to hive files in the correct format). The backups were normal NTFS filesystems, no special tool was needed to read them. It automatically cleaned out the oldest previous versions when space ran out (unlike Windows 7 backup which apparently simply starts failing the the backup media fills.) It copied all file attributes including security. Cons: It doesn't deal well with junction points, symbolic links, and hard links. It didn't run as a service without lots of help from firesrv or srvany, and then you couldn't interact with the GUI. Running as a service was necessary to be able to mirror protected OS files. It didn't have open file handling, except for registry hives. I guess that the file-by-file archive and replacement could leave mismatched sets of files, if the mirror was interrupted. This would be the advantage of incremental backup techniques that require old full backup + all intermediate incremental backups to restore. But I don't see this as presenting much of a problem, you'd really only have a boot failure if you had a mixture of pre- and post-service pack files, and I can run a full image backup using another tool before applying a service pack. Does anyone know of a tool that does both full-system backup and storage of old versions of files like Lazy Mirror did (without storing the same data multiple times), and also can run as a service in Windows 7? Free is best of course, but a reasonably priced paid program (e.g. It would be absolutely awesome if it also triggered a backup/mirror pass when a particular external drive was plugged in and generated popup warnings if backups hadn't been run recently)

• Kernel upgrade CentOS 5.3 mount: could not find filesystem '/dev/root'

  - by matt

  We have a CentOS 5.3 x64 server that by default runs kernel version 2.6.18-164.11.1 and we are attempting to upgrade the box to 2.6.31.12 The drive is LVM +ext3, and the problem I'm having is when I upgrade the kernel and attempt to boot from it, no matter what version of the kernel I use, I get /dev/root not found towards the end of the boot process, and the kernel panics, and than reboots. I'm installing the kernel exactly as it says in this doc. I've tried it "The centOS way " using make rpm and than installing that. I've updated my mkinitrd. The most interesting part of this problem is that it has been so frustrating that I decided to try and clean install centos on an identical machine without LVM, and the result is EXACTLY the same. After upgrading the kernel, I get /dev/root not found. Does anyone know how to fix this, or what information would be relevant to remedy it? I'm open to try anything at this point. One more interesting thing about this problem is that in the new version of the kernel, during boot it complains that dm-mapper is started twice, than panics right after that. I've tried this with other kernel versions, and the result is the same. What am I missing here? If you need any more files, please just ask. Linux cg 2.6.18-164.11.1.el5 #1 SMP Wed Jan 20 07:32:21 EST 2010 x86_64 x86_64 x86_64 GNU/Linux /dev/VolGroup00/LogVol00 / ext3 defaults 1 1 LABEL=/boot /boot ext3 defaults 1 2 tmpfs /dev/shm tmpfs defaults 0 0 devpts /dev/pts devpts gid=5,mode=620 0 0 sysfs /sys sysfs defaults 0 0 proc /proc proc defaults 0 0 /dev/VolGroup00/LogVol01 swap swap defaults 0 0 default=1 timeout=5 splashimage=(hd0,0)/grub/splash.xpm.gz hiddenmenu title CentOS (2.6.31.12-rt20) //NOT WORKING!!!! root (hd0,0) kernel /vmlinuz-2.6.31.12-rt20 ro root=/dev/VolGroup00/LogVol00 isolcpus=8,9,10,11,12,13,14,15 panic=10 initrd /initrd-2.6.31.12-rt20.img title CentOS (2.6.18-164.11.1.el5) //WORKING!! root (hd0,0) kernel /vmlinuz-2.6.18-164.11.1.el5 ro root=/dev/VolGroup00/LogVol00 isolcpus=8,9,10,11,12,13,14,15 panic=10 initrd /initrd-2.6.18-164.11.1.el5.img

• Secret, unlogged, transparent, case-sensitive proxy in IIS6?

  - by Ian Boyd

  Does IIS have a secret, unlogged, transparent, case-sensitive proxy built into it? A file exists on the web-server: GET http://www.stackoverflow.com/javascript/ModifyQuoteArea.js HTTP/1.1 Accept: text/html, application/xhtml+xml, */* Accept-Language: en-US User-Agent: Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0) Accept-Encoding: gzip, deflate Connection: Keep-Alive Host: www.stackoverflow.com HTTP/1.1 200 OK Connection: Keep-Alive Content-Length: 29246 Date: Mon, 07 Mar 2011 14:20:07 GMT Content-Type: application/x-javascript ETag: "5a0a6178edacb1:1c51" Server: Microsoft-IIS/6.0 Last-Modified: Fri, 02 Tue 2010 17:03:32 GMT Accept-Ranges: bytes X-Powered-By: ASP.NET ... Problem is that a changes made to the file will not get served, the old (i.e. February of last year) version keeps getting served: HTTP/1.1 200 OK Connection: Keep-Alive Content-Length: 29246 Date: Mon, 07 Mar 2011 14:23:07 GMT Content-Type: application/x-javascript ETag: "5a0a6178edacb1:1c51" Server: Microsoft-IIS/6.0 Last-Modified: Fri, 02 Tue 2010 17:03:32 GMT Accept-Ranges: bytes X-Powered-By: ASP.NET ... The same old file gets served, even though we've: renamed the file deleted the file restarted IIS The request for this file does not appear in the IIS logs (e.g. C:\WINNT\System32\LogFiles\W3SVC7\) And this only happens from the outside (i.e. the internet). If you issue the request locally on the server, then you will: - get the current file (file there) - 404 (file renamed) - 404 (file deleted) But if i change the case of the requested resource, i.e.: GET http://www.stackoverflow.com/javascript/MoDiFyQuOtEArEa.js HTTP/1.1 Accept: text/html, application/xhtml+xml, */* Accept-Language: en-US User-Agent: Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0) Accept-Encoding: gzip, deflate Connection: Keep-Alive Host: www.stackoverflow.com Note: MoDiFyQuOtEArEa.js verses ModifyQuoteArea.js Then i do get the proper file (or get the 404 as i expect if the file is renamed or deleted). But any subsequent changes to the file will not show up until i change the case of the file i'm asking for. Checking the IIS logs all indicate that the (internet) requests are all coming the correct client on the internet (i.e. not from some intermediate proxy). Since the file doesn't exist on the hard drive anymore, i conclude that there is a proxy. The requests serviced from this proxy are not logged in the IIS logs. The requests for new files are logged, and from the client IP, not a proxy IP. The proxy is case sensitivie. This does not sound like something Microsoft, or IIS, would do: - a transparent proxy - case-sensitivie - unlogged - surviving restarts of IIS - surviving in a cache for hours i can't believe that our customer's IIS is doing these things. i'm assuming there is some other transparent proxy in front of IIS. Or, does IIS have a transparent, unlogged, case-sensitive, memory based, proxy, that caches content for at least 7 hours? (Come Monday morning, IIS is serving the correct file, unlogged).

• Intermittent Disconnection of Client Computers from Domain Server

  - by dilip nagle

  The Background: I have Windows 2008 server Enterprise Version with 25 user cal licences. It has a domain and all users and a network shared HP printer in it. The Server has two network cards and both these cards as well as all client machines are on IP addressing scheme of 192.168.1.* with subnetmask 255.255.255.0. Of the two network cards viz. 192.168.1.231 and 192.168.1.233, only 192.168.1.231 is registered with DNS. In 192.168.1.233(i.e. 2nd network card) has default getway as 192.168.1.231 and dns address as 192.168.1.231. The Server has three hard disks with capacities as 500gb, 500gb and 1TB and are partitioned as (C,D,E), (F,G) and (K) with partition K having all user data into various Shared Folders. Each of these folders(On Partition K), are mapped onto each user's computer as per the right of access given to them. The Problem: The Server was installed about 6 months ago and till date not even once, the Server has Hung or has given any problem. All the Clients computers are able to run the web based software from their computers via ip address, e.g. http://192.168.1.231/webERP/default.aspx. However, occassionally, when any client computer tries to browse network mappings, it hangs. Again, there is no fixed pattern. This may happen after running smoothly for say 3 days. On each Client's machine, the network settings are as follows: IP Address: 192.168.1.* where * is 1,2,3 .... Sunnetmask: 255.255.255.0 defauly getway: 192.168.1.231 Which is a server card and DNS address. preferred DNS Server: 192.168.1.231 In Advanced Tab under Wins: LMHostLookup is Unticked and default is radio buttoned. Ideally, I would have loved to have Disabled NETBIOS over TCP/IP but some network printers do not get accessed if this option is enabled(ie. Radio Buttoned). Bacause Disabling Netbios will drastically reduce traffic of NETBIOS broadcasting to all the computers on the net to do naming resolution. On Server, I have WINs Running which I have Scavanged Records, verified Database Integrity etc, removed Tombstoned Records etc. The Critical Errors shown only once a day when the server is statred are 4224(WINS) and 12923 - Server Licencing failed to Update DNS Record. I fail to understand as why do client machines HANG when they try to browse mapped network shared folders on K Drive. Kindly Advice

• Brand new Mac Pro tower fan suddenly runs full-tilt

  - by Caffeine Coma

  My Quad-Core Mac Pro tower is two days old. Initially, I was impressed with how quiet it was compared to my older Macbook Pro. Then on day two, for some reason it started running very loudly. It's not just a "little" loud- my wife walked into the room and asked what the noise was. At first I thought this was just because I was hitting the CPU a bit (importing my iPhone library into iLife '09, and running Eclipse). But now that that's done, Activity Monitor shows a virtually idle CPU; there's nothing running that ought to be causing this, as far as I can tell. I tried powering it off & letting it cool down for a few minutes to no avail; about 10 seconds after powering up, the box gets loud again. I took a look at it with the side cover off, and it seems to be the fan near the top middle, between the power supply and the disk drive. It can't be a dust issue, as the machine is only 2 days old (and I peeked inside anyway just to be sure- clean). I did do a software update over the past 24 hours or so, but I can't say that it occurred immediately after that. I also did a migration of my old apps and data from my MBPro, for what it's worth. Why is it suddenly so loud? How can I monitor the fan speed and various system temperatures? Here's a link to my temps and fan speeds. UPDATE 1: Took it to the Apple Store. They took it in the back (where it's presumably quieter) and ran a fan diagnostic; no problems were found. The guy also told me that it was "a little loud", but normal. I don't buy it. It was virtually silent the first 24 hours I was using it. They would not replace/service it in the store (grrr... that's why I went there, as directed by Apple Care) but said I could get a replacement from the online store, as it was just purchased. I think I will try that. UPDATE 2: Apple is letting me send it back for a replacement. Glad to see so many responses to this question mentioning that the MacPros are usually silent; it's not all just in my head. :-)

• File Not Found error launching Guest OS in a non-administrator user account

  - by ToreTrygg

  Hi, I am running Fusion 2.0.6 (196839) on an iMac running 10.6.2 with 3 user accounts (1 Administrator). I have Fusion set up to share the Guest OS, and it's been working splendidly for nearly a year. Within the Guest OS (Windows XP PRO), there are also 3 user accounts (1 Administrator). Last night I went to back up my VM to an external drive, and to minimize the file size and transfer time, I deleted all Snapshots but the most-recent one. I then backed up the VM externally (28.23 GB). Today, one of my users tried to launch the Guest OS from within her user account, and received the following error message: "File Not Found: Windows XP Pro-000006.vmdk "This file is required to power on this virtual machine. If this file was moved, please provide its new location." My two choices are Cancel and Browse. When I browse, I can locate the Windows XP Pro-000006.vmdk file, which appears to be contained within the VM file (Windows XP Pro.vmwarevm). However, it still won't launch from a non-Admin user account. If I view the package contents of the VM file from the user account, the above file is present and appears to be created upon each launch of the Guest OS. If I go back to my Administrator account on the Mac and then launch Fusion, the Guest OS works perfectly for all 3 user accounts within XP Pro. I have tried to delete the Guest OS from Fusion's Library within the problem user account, then re-connect it to that Library, but the result is the same. The Guest OS data integrity is 100% -- but is accessible only from the OS X Administrator account. This problem only surfaced after deleting several older Snapshots. Again, the data is there, the Guest OS powers up normally in the Mac's Administrator account, but persistently returns the above error when attempting to power on from a non-Admin account on the Mac. I'm not sure how this is affecting the error, but when I look at Hard Disk Settings, the "unable-to-locate" file is the filename of the virtual HD. I don't want to make any changes to my (working) VM without any advice from the knowledgeable people on this forum. Any help will be greatly appreciated, thanks!

• Creating a USB stick for installing centos 6.x using DVD1 and DVD2 iso files

  - by user250563

  First, we create 2 partitions on the USB stick that is let's say 16GB. first partition is let's say only 1GB and the second partition is the rest of what is available. after we "w" write the changes, the USB now has 2 partitions. 1 is 1GB 1 is more than 14GB so , we have... sdb1 and sdb2 now. now we need to turn these partitions into filesystems some say i should run these commands after those procedures. mkfs.vfat -F 32 /dev/sdb1 mkfs.ext3 /dev/sdb2 but some web pages recommend using: mkfs.vfat -n BOOT /dev/sdb1 mkfs.ext2 -m 0 -b 4096 -L DATA /dev/sdb2 which is it? so let's say the DVDs are called: CentOS-6.4-x86_64-bin-DVD1.iso CentOS-6.4-x86_64-bin-DVD2.iso so we make a directory: mkdir -p /mnt/dvd1 and then mount it: mount -o loop CentOS-6.4-x86_64-bin-DVD1.iso /mnt/dvd1 and i suppose we don't make a directory for dvd2 and we don't have to mount it ? at this point i do not know what should be done. but i think this step might be next: we make the USB bootable by finding the file named mbr.bin and then moving it to there via these commnad. dd conv=notrunc bs=440 count=1 if=/usr/lib/syslinux/mbr.bin of=/dev/sdb parted /dev/sdb set 1 boot on in other words we are "dd-ing it to 'sdb' not sdb1' or 'sdb2'. and then we use parted to set the boot to on for sdb so far everything looks good? here is the confusing parts.. how exactly do i move these iso files to the usb drive? EVERYTHING BELOW IS A GUESS. so at this point i should copy the folder /mnt/dvd1/isolinux to usb's sdb1 or sdb2 ? rename it to syslinux ? and then inside this syslinux folder there will be a file called... isolinux.cfg ? which should be renamed to syslinux.cfg ? and then copy the contents of /mnt/dvd1/images/* to USB's sdb2 ? but i think i am also suppose to copy and paste the both CentOS-6.4-x86_64-bin-DVD1.iso CentOS-6.4-x86_64-bin-DVD2.iso somewhere into this USB's sdb2 partition, correct ? almost like a drag and drop kind of a thing? or do they go into any folders ? centos' own web site has some instructions but those instructions do not work. http://wiki.centos.org/HowTos/InstallFromUSBkey i once got this working but things got ruined, i have to do it again and this time take notes.

• Looking for a Software to harden Windows machines

  - by MosheH

  I'm a network administrator of a small/medium network. I'm looking for a software (Free or Not) which can harden Windows Computers (XP And Win7) for the propose of hardening standalone desktop computers (not in domain network). Note: The computers are completely isolated (standalone), so i can't use active directory group policy. moreover, there are too many restriction that i need to apply, so it is not particle to set it up manual (one by one). Basically what I’m looking for is a software that can restrict and disable access for specific user accounts on the system. For Example: User john can only open one application and nothing else -- He don’t see no icon on the desktop or start menu, except for one or two applications which i want to allow. He can't Right click on the desktop, the task-bar icons are not shown, there is no folder options, etc... User marry can open a specific application and copy data to one folder on D drive. User Dan, have access to all drives but cannot install software, and so on... So far ,I've found only the following solutions, but they all seems to miss one or more feature: Desktop restriction Software 1. Faronics WINSelect The application seems to answer most of our needs except one feature which is very important to us but seems to be missing from WINSelect, which is "restriction per profile". WINSelect only allow to set up restrictions which are applied system-wide. If I have multiple user accounts on the system and want to apply different restrictions for each user, I cant. Deskman (No Restriction per user)- Same thing, no restriction per profile. Desktop Security Rx - not relevant, No Win7 Support. The only software that I've found which is offering a restriction per profile is " 1st Security Agent ". but its GUI is very complicated and not very intuitive. It's worth to mention that I'm not looking for "Internet Kiosk software" although they share some features with the one I need. All I need is a software (like http://www.faronics.com/standard/winselect/) that is offering a way to restrict Windows user interface. So IF anybody know an Hardening software which allows to set-up user restrictions on Windows systems, It will be a big, big, big help for me! Thanks to you all

• Fast user switching suddenly stopped working on my Windows XP Prof machine

  - by John

  When I start Win XP SP2 I get to the welcome screen with no user names displayed. I then press Alt+Ctrl+Del twice and type in the username and then am able to login to Windows. When I go to user accounts in Control Panel I get the error message cells.item(...) is null or not an object. When I go to computer administration and then local users and groups there are no users listed under users but the groups is listed. I did a windows repair with no luck. I tried doing restore points but it said they didn’t work. Please help? My wife and I have been using fast user switching on out computer for years with no problem. Beginning a few months ago, I started Win XP Prof one day I get to the welcome screen with no user names displayed. I then press Alt+Ctrl+Del twice and type in the username and then am able to login to Windows with an account of owner. When I go to user accounts in Control Panel I get the error message cells.item(...) is null or not an object. When I go to computer administration and then local users and groups there are no users listed under users but the groups are listed. I have done system point restores and imports of exports of the registry I take with import. I have tried everything under safe mode and it makes no difference. This followed a Microsoft update the night before as I left the computer on. I tried to do a restore point but all my restore points failed and could not backout the MS updates. I was working with a fellow from Microsoft and he had me do all kinds of things but to no avail. He seems to think a DLL file is corrupt but which one? Finally in desperation he sent me a new OS XP Prof SP3 disk and I installed it and it wiped my hard drive. Luckily I took an Acronis Image backup first so I easily restored my system. I do not want to do a fresh windows update as it is heavily customized and worked fine up to that point. This has been going on for months, Thanks John

• How to bind old user's SID to new user to remain NTFS file ownership and permissions after freshly reinstall of Windows?

  - by LiuYan ??

  Each time we reinstalled Windows, it will create a new SID for user even the username is as same as before. // example (not real SID format, just show the problem) user SID -------------------- liuyan S-old-501 // old SID before reinstall liuyan S-new-501 // new SID after reinstall The annoying problem after reinstall is NTFS file owership and permissions on hard drive disk are still associated with old user's SID. I want to keep the ownership and permission setting of NTFS files, then want to let the new user take the old user's SID, so that I can access files as before without permission problem. The cacls command line tool can't be used in such situation, because the file does belongs to new user, so it will failed with Access is denied error. and it can't change ownership. Even if I can change the owership via SubInACL tool, cacls can't remove the old user's permission because the old user does not exist on new installation, and can't copy the old user's permission to new user. So, can we simply bind old user's SID to new user on the freshly installed Windows ? Sample test batch @echo off REM Additional tools used in this script REM PsGetSid http://technet.microsoft.com/en-us/sysinternals/bb897417 REM SubInACL http://www.microsoft.com/en-us/download/details.aspx?id=23510 REM REM make sure these tools are added into PATH set account=MyUserAccount set password=long-password set dir=test set file=test.txt echo Creating user [%account%] with password [%password%]... pause net user %account% %password% /add psgetsid %account% echo Done ! echo Making directory [%dir%] ... pause mkdir %dir% dir %dir%* /q echo Done ! echo Changing permissions of directory [%dir%]: only [%account%] and [%UserDomain%\%UserName%] has full access permission... pause cacls %dir% /G %account%:F cacls %dir% /E /G %UserDomain%\%UserName%:F dir %dir%* /q cacls %dir% echo Done ! echo Changing ownership of directory [%dir%] to [%account%]... pause subinacl /file %dir% /setowner=%account% dir %dir%* /q echo Done ! echo RunAs [%account%] user to write a file [%file%] in directory [%dir%]... pause runas /noprofile /env /user:%account% "cmd /k echo some text %DATE% %TIME% > %dir%\%file%" dir %dir% /q echo Done ! echo Deleting and Recreating user [%account%] (reinstall simulation) ... pause net user %account% /delete net user %account% %password% /add psgetsid %account% echo Done ! %account% is recreated, it has a new SID now echo Now, use this "same" account [%account%] to access [%dir%], it will failed with "Access is denied" pause runas /noprofile /env /user:%account% "cmd /k cacls %dir%" REM runas /noprofile /env /user:%account% "cmd /k type %dir%\%file%" echo Done ! echo Changing ownership of directory [%dir%] to NEW [%account%]... pause subinacl /file %dir% /setowner=%account% dir %dir%* /q cacls %dir% echo Done ! As you can see, "Account Domain not found" is actually the OLD [%account%] user echo Deleting user [%account%] ... pause net user %account% /delete echo Done ! echo Deleting directory [%dir%]... pause rmdir %dir% /s /q echo Done !

• Adobe Reader not loading form content

  - by wullxz

  We have an FDL file which is used to offer an online application possibility. The FDL is filled out and sent to a mailbox. When I open the received file, Adobe Reader starts, loads the document in Internet Explorer (had to change my default browser because it doesn't work in chrome - the customer uses IE as default) and displays a warning that Adobe Reader has blocked the connection to the server where the initial document is saved: I can then click on "Trust this document once" (translated by me!) or "Add this host to trusted hosts" (also translated by me!). The second option doesn't work at all. The first option works but is a little bit annoying. I looked into Adobe Readers options (Edit - "Voreinstellungen" in german / the last option - Security (advanced)) and found the possibility to add hosts, files and directories or allow Adobe Reader to use the "Trusted Websites" list from Internetoptions. When I add the website either to Trusted Websites or the trusted list in Adobe Readers options, the warning doesn't pop up but the content in the prefilled (by the applicant) input boxes of the document doesn't show up on Windows 7 but it does show up on Windows XP. This Screenshot shows the settings window described in the last paragraph. The big input box at the bottom normally holds the trusted files/directories/hosts list. System Information: Windows 7 Enterprise x64 Adobe Reader X multiple IE versions (mine is latest but there's also IE 7 or 8) How do I get Adobe Reader to load the content of the form? This behaviour can be reproduced on a PC. When opening an fdf from a command line the form fields are blank even though there is data in the fdf and the pdf is located in a mnaully entered trsuted folder. Steps to reproduce: Clean install a Windows 7 PC (or use a virtual box) Map a network drive to a shared folder with a subfolder e.g. c:\test\docs becomes m:\docs Set security permissions to allow full control to everyone Add an fdf and a matching pdf file in the subfolder Manually add m:\docs to each of the trusted folders in the trust manager registry settings Ensure that Enhanced Security is on Run a command line to open the fdf file Expected result: pdf is opened in Adobe Reader with form fields filled out with data Actual results: pdf is opened with blank fields 'Yellow bar' appears asking to add document to trusted locations It appears that Adobe Reader XI is ignoring the privileged locations entries in the registry. Adding the document via the 'yellow bar' adds the individual document, with the same folder, to the privileged locations but means that the process has to be repeated for every document that needs to be opened from the folder.
