• Does a 3ware "ECC-ERROR" matter on a JBOD when I have ZFS?

  - by Stefan Lasiewski

  I have a FreeBSD 8.x machine running ZFS and with a 3ware 9690SA controller. The 3ware controller shows an ECC-ERROR with one of the disks: //host> /c0 show VPort Status Unit Size Type Phy Encl-Slot Model ------------------------------------------------------------------------------ p0 OK u0 279.39 GB SAS 0 - SEAGATE ST3300657SS p1 OK u0 279.39 GB SAS 1 - SEAGATE ST3300657SS p2 OK u1 931.51 GB SAS 2 - SEAGATE ST31000640SS p3 ECC-ERROR u2 931.51 GB SAS 3 - SEAGATE ST31000640SS p4 OK u3 931.51 GB SAS 4 - SEAGATE ST31000640SS /c0 show events shows no ECC errors in it's recent history. ZFS does not currently detect any errors. zpool status says No known data errors My question: Is this ECC-ERROR something that I need to be concerned about? According to the 3ware CLI 9.5.2 Manual, an ECC-ERROR means that the 3ware controller caught a read-error for one or more sectors on this drive. This sometimes occurs when a RAID array is recovering from a failed disk. I believe that ECC-ERRORS can also be detected when the 3ware Controller verifies each disk. None of the drives have failed and thus there was no drive rebuild, so I assume that 3ware discovered a bad sector when it ran it's weekly auto-verify scan of the disks. Is this a safe assumption? According to our logs, ZFS has not detected any bad sectors on this drive. ZFS can work around read errors -- if ZFS detects a bad sector on the drive, it will simply mark that sector as bad and never use it again. From the ZFS perspective one bad sector isn't a big deal, although it might indicate that the drive is starting to go bad.

• Rebinding Keys on a Dell Keyboard

  - by Maarx

  I have a Dell Multimedia Keyboard, similar to this one: It has many non-standard keys, like the small circular ones across the top, and the "Multimedia" keys above INSERT/HOME/PAGE_UP. They can be rebound through simple registry entries. Some sample ones are included below: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\AppKey] [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\AppKey\15] "ShellExecute"="C:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe http://mail.google.com/mail/#inbox" [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\AppKey\16] "Association"=".cda" [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\AppKey\17] "ShellExecute"="C:\\Windows\\System32\\SnippingTool.exe" [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\AppKey\18] "ShellExecute"="calc.exe" [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\AppKey\7] "Association"="http" I've rebound the "MAIL" key to, instead of booting Outlook, to booting Firefox directed at my G-Mail account. I've rebound the button that would normally open "MY COMPUTER" to instead boot the Windows 7 "Snipping Tool", something I find very useful. Now, I'm looking to do some other things that I don't already know how to do. Note that answering this question doesn't necessarily require any knowledge about the keyboard or rebinding the keys: I can add, for any given key, a "ShellExecute" entry, and it will simply execute the following command as if it was typed at a Command Prompt. (I'm aware I dumbed that down rather significantly, but bear with me. I'm not really a Windows guy myself.) I use the volume knob for it's intended purpose, to change volume. I would like to change, however, a different key, to "reset" the Windows volume level back to exactly 50%, or, as it refers to it, "50", on it's 0-100 scale. I'm looking for the "program" (what I would type at a command prompt? these are still just Sys32 programs in the PATH, aren't they?) that, I imagine, would take arguments, to change Sound/Volume settings under Windows 7. Perhaps, for clarification, something that might take the form "C: SetVolume -slevel 50" or something.

• BGP path prepended route not listed anywhere

  - by Julien Vehent

  We have a simple multi-homed setup with two routers that advertise our AS to two ISP. The second ISP (ISP B) is only used for backup when ISP A goes down, so we prepended our AS 3 times on this route. I spend a couple of hours this morning poking at looking glass routers all over the internet, and none of them list our backup route with the prepended path. I checked the south african internet exchange, the london internet exchange, oregon internet exchange and a couple dozen ISPs. All of them have multiples routes through ISP A, often with 3 or 4 hops. The route through ISP B should, at least, appear somewhere and have 5 or 6 hops. But I couldn't find it anywhere. (I checked the full bgp tables on the looking glass routers, using show ip bgp 65000) My questions are: Is there a limit to the size of a route after which most routers will simply discard the route ? Is our backup route even going to work when ISP A goes down, if no router knows about it ? Our two routers are connected on iBGP. Would it be possible that the route through ISPB is not announced because the iBGP session prefers the route through ISPA ? This is what non-exist-map and advertise-map are supposed to do, but none of those are used in either routers.

• ffmpeg rotate mp4 90º

  - by shox

  Hi, can I rotate(+save / reencode) a .mp4 with ffmpeg? The only thing I found was on the mailinglist saying -vfilters "rotate=90" but ffmpeg says no vfilters. Tried -vf, it says there is no rotate. If I try to do it in VLC it simply does not rotate and kills the audio (did the vlc encoding EVER work? Every single freakin video I throw at it gets fu****d up in some way -_- ) I'm on a MAC and don't have iWork. Any ideas? Thanks FFmpeg version git-svn-r23607, Copyright (c) 2000-2010 the FFmpeg developers built on Jun 14 2010 23:52:55 with gcc 4.2.1 (Apple Inc. build 5659) configuration: libavutil 50.19. 0 / 50.19. 0 libavcodec 52.76. 0 / 52.76. 0 libavformat 52.68. 0 / 52.68. 0 libavdevice 52. 2. 0 / 52. 2. 0 libavfilter 1.20. 0 / 1.20. 0 libswscale 0.11. 0 / 0.11. 0 Hyper fast Audio and Video encoder

• Windows 3 Animated Background/Desktop/Wallpaper

  - by Synetech

  In the summer of 1995, I visited some family in Los Angeles. My uncle had a computer with Windows 3 (or some version thereof since Windows 95 had not been released yet). In Windows 3, there was no desktop or wallpaper like in later versions; instead you could set it to a simple pattern (still possible in later versions before XP) like hounds-tooth or bricks (interestingly, there seems to be next to nothing available on the Internet about this anymore; no screenshots and almost no pages). I recall being amused when I found a program (on the still young “world-wide web”) that would actually let you set an animated background. It was smooth and fluid and was quite an amazing thing at the time. If I recall correctly, it had several built-in animations including one of a light-orange-pink background over which storks flew towards the top-left, possibly with some light stuff floating in the “background” (they were actually animated and flapped their wings, not simply translated coordinates). The storks were somewhat simplified, black-line drawings. Over the years, I’ve tried finding it again a few times but never could. Worse, it’s become harder and harder over time as new programs came out and polluted the search results. I’m hoping that someone remembers this software and knows some useful information like the author or where to download it. (No, it’s not ScreenPaper. That was created in 1997 to let you set a screensaver as the Windows 95/NT4 background. This was at least two years earlier for Windows 3 and I’m almost certain it had these animations built-in—I don’t recall any stork screensavers for Windows 3.)

• How to install a private user script in Chrome 21+?

  - by Mathias Bynens

  In Chrome 20 and older versions, you could simply open any .user.js file in Chrome and it would prompt you to install the user script. However, in Chrome 21 and up, it downloads the file instead, and displays a warning at the top saying “Extensions, apps, and user scripts can only be added from the Chrome Web Store”. The “Learn More” link points to http://support.google.com/chrome_webstore/bin/answer.py?hl=en&answer=2664769, but that page doesn’t say anything about user scripts, only about extensions in .crx format, apps, and themes. This part sounded interesting: Enterprise Administrators: You can specify URLs that are allowed to install extensions, apps, and themes directly through the ExtensionInstallSources policy. So, I ran the following commands, then restarted Chrome and Chrome Canary: defaults write com.google.Chrome ExtensionInstallSources -array "https://gist.github.com/*" defaults write com.google.Chrome.canary ExtensionInstallSources -array "https://gist.github.com/*" Sadly, these settings only seem to affect extensions, apps, and themes (as it says in the text), not user scripts. (I’ve filed a bug asking to make this setting affect user scripts as well.) Any ideas on how to install a private user script (that I don’t want to add to the Chrome Web Store) in Chrome 21+? Update: The problem was that gist.github.com’s raw URLs redirect to a different domain. So, use these commands instead: # Allow installing user scripts via GitHub or Userscripts.org defaults write com.google.Chrome ExtensionInstallSources -array "https://*.github.com/*" "http://userscripts.org/*" defaults write com.google.Chrome.canary ExtensionInstallSources -array "https://*.github.com/*" "http://userscripts.org/*" This works!

• Poor Write Performance in VM inside Proxmox PVE 2.0

  - by sorsenne

  I am running a PVE 2.0 on a decent Hardware (2 SATA HDDs as RAID1, 12GB RAM, i7 CPU) but the I/O Performance is very poor inside the VM (Ubuntu 11.10 Server).

• How do I export address book from N97

  - by mplungjan

  Hi, I need to copy my numbers from my private Nokia to my office BB. I have not found a way to export my phone numbers from ovi or elsewhere. On Mac iSync stopped working with snow leopard and OVI on windows does not export. I do not mind using a windows suggestion. I lost a description on how to use the ovi backup files in another program. What I have done so far terminal: sudo open -a iSync.app - it launched but iSync said "this device is not supported by iSync" went here http://europe.nokia.com/support/product-support/isync/compatibility-and-download found a plugin (I am sure that was not there a while ago :| ) Checked software version 22.0.110 installed plugin Ran iSync which found and installed my N97 device successfully. synced. It stopped with The connection was lost while talking to the phone. http://discussions.europe.nokia.com/t5/Nseries-and-S60-Smartphones/N97-iSync-Multimedia-Transfer-Modem/m-p/568560 no news since Jan 2010. Tried to download and install http://best-vcard.en.softonic.com/symbian but the installer fails :( I simply do not understand why Nokia is giving us such a hard time. I would not have considered switching from Nokia if Mac had been better supported. It is so frustrating that they just seem not to care losing Nokia fanbois like me - especially since I am this outspoken on the net and what i say on popular forums gets indexed by google fast. I am very close to just go iPhone here. Hope someone has Nokia's ears UPDATE: I Downloaded NbuExplorer from sourceforge. It will extract everything from an OVI backup into VCF, VCS and VMG files. Very useful software and free.

• How to "swap in" again memory from page file to physical memory in Windows at once (like linux swap-off)

  - by Arnout

  Is there a way to swap back in (to put back all the memory data that was put into the page file (or swap, whatever you prefer)) memory on a windows PC? On linux, one can easily do this with the swapoff /dev/sdaX, where X is the swap partition. On windows, it seems to ask me to reboot each time.. The reason I'd like to do this, is that, even though swapping out the data to the swap file allows me to play a resource-hungry game fully in physical ram, when I stop the game, all the rest of my programs run slow. This is or course normal; all the programs were pushed into the page file because my RAM was too small, and all memory access to those programs after gaming bumps into hard page faults, with major delays and some frustration as a consequence. However, that frustration could easily be avoided, by simply allowing the PC to copy all data back into the physical memory for a minute or so, and then resume working on a fast working PC! (rather than having to endure the slowness -while- working) Thanks in advance for any advice on this! Kind regards

• SSD, AHCI and write performance

  - by Dan

  We've started to deploy SSD drives to our developers workstations. At this moment we're having the unpleasant surprise that the systems using the new SSDs often freeze, with the HDD activity led blinking or being continuously on. Benchmarks shows read speeds around 180 MB/s, but write speeds around 5 MB/s. All developers are using Windows 7 Enterprise, 64 bit, SP1. One of our developers suggested (based on his experience) the following sequence: backup the workstation use a tool to completely erase the SSD make sure AHCI is enabled in BIOS install Windows restore from backup So far, this procedure seems to work (we're still testing, but write speed seems to be 120 MB/s). There are some questions in this context: why do we have to completely reinstall Windows? Is it possible to clean the SSD without reinstalling Windows? Is there a reliable tool? If AHCI was disabled when Windows was installed and we enable it, shouldn't this be enough to correct the write performance issue? If we have to completely erase the SSDs, does this mean the SSDs we've received were used before (SH)? I'm wondering this because the package I've got was open (I didn't think about it at that time, as I considered one of my coworkers simply took a peek inside the package). Has anyone seen a similar problem before?

• Get rid of gray brackets arond editable text in restricted Word docs

  - by Brendan

  I'm trying to work out a problem in Word that I thought was simply a glitch from 2003 until we upgraded to 2010 and the problem persisted. For our corporate letterhead, we set up the template with placeholder text, highlight the text, and then make the document read-only with the exception of the selected text. The editable text turns yellow and gains these brackets around them: Once these brackets appear, they'll always show on the screen. That I can handle, though I'd like to learn how to hide them on-screen if that's possible. When the document is printed while protected, it works fine. When the document is printed while NOT protected, part of the bracket shows up on the paper! I guess the ultimate question is, how can I get rid of the brackets altogether? I can see why they exist but in my use case they create more problems than they solve. I'd like someone to be able to read the doc without seeing brackets, and I'd like other people in my department to be able to print without having to re-restrict it first. I tried to turn off bookmarks because that's what seemed to come up when I searched around, but that didn't do anything.

• Acronis Disk Director AFTER Clone Disk error: PXE-E61: Media test failure, check cable

  - by Kairan

  Used Acronis Disk Director on my desktop, plugged in the laptop drive 240GB SSD (USB) and the new hard drive 500GB SSD (usb) and the copy seemed to be fine. I didnt see any error messages but I didnt stare at it for 3 hours either. The clone disk of course the Toshiba hidden restore partition, the primary partition C drive and the active (boot?) partition and yes, did check box for copy NT signature. The computer boots up fine most of the time, but it seems that when the computer goes to sleep (i believe its sleep, hard to do much testing during school) or hibernate or reboot it will sometimes display this message: Intel(R) Boot Agent GE v1.3.52 Copyright (C) 1997-2010, Intel Corporation PXE-E61: Media test failure, check cable PXE-M0F: Exiting Intel Boot Agent Insert system disk in drive. Press any key when ready... Of course any key does nothing but repeat a similar method. However, if I press the power button on the laptop (Toshiba Portege R705, Win 7 Pro 64-bit) it puts computer into hibernate. After hibernating I press power button again and it comes out of hibernation without any odd messages or problems described above... so apparently that is my TEMP fix. Another recent issue I noticed is on occasion when creating a new folder or modifying something in the system variables, other random areas I will get a message: "The Stub received bad data" and simply retry the task and it works. Perhaps these two issues are linked.

• What keeps you from changing your public IP address and wreak havok?

  - by Whitemage

  An interesting question was asked to me and I did not know what to answer.. So I'll ask here. Let's say I subscribed to an ISP and I'm using cable internet access. ISP gives me a public IP address of 60.61.62.63. What keeps me from changing this IP address to, let's say, 60.61.62.75 and mess with another consumer's internet access? For the sake of this argument, let's say that this other IP address is also owned by the same ISP. Also, let's assume that it's possible for me to go into the cable modem settings and manually change the IP address. Under a business contract where you are allocated static addresses, you are also assigned a default gaetway, a network address and a broadcast address. So that's 3 addresses the ISP "loses" to you. That seems very wastefull for dynamically assigned IP addresses where the majority of customers are.. Could they simply be using static arps? ACLs? Other simple mechanisms? Anyone who worked at an ISP would be willing to explain this a bit?

• PHP 5.3.5 Windows installer missing php_ldap.dll

  - by nmjk

  I'm working with Windows Server 2008, Apache 2.2. I'm using php-5.3.5-Win32-VC6-x86.msi as the installer, using the threadsafe version. I've gone through the install process four or five times just to make sure that I'm not missing anything ridiculous, but I don't think I am. The problem is that the php_ldap.dll extension simply doesn't seem to exist. It's not present in the installer interface (where the user is asked to choose which extensions to install), and it definitely doesn't appear in the ext/ directory after install. I found a lot of mentions of this issue for 5.3.3, including links to download the extension individually. Those links no longer exist, of course, and besides: they were for 5.3.3. I'd really rather use an extension that belongs with PHP 5.3.5. Anyone else encounter this problem? Any ideas as to what's going wrong? Anyone seen acknowledgement by the PHP folks that the file is indeed missing, and that it's an oversight? It's quite a frustration because the server I'm building has no purpose if I don't have PHP LDAP support. Cheers all, and thanks in advance for your assistance.

• Why doesn't my symbolic link work?

  - by orokusaki

  I'm trying to better understand symbolic links... and not having very much luck. This is my actual shell output with username/host changed: username@host:~$ mkdir actual username@host:~$ mkdir proper username@host:~$ touch actual/file-1.txt username@host:~$ echo "file 1" > actual/file-1.txt username@host:~$ touch actual/file-2.txt username@host:~$ echo "file 2" > actual/file-2.txt username@host:~$ ln -s actual/file-1.txt actual/file-2.txt proper username@host:~$ # Now, try to use the files through their links username@host:~$ cat proper/file-1.txt cat: proper/file-1.txt: No such file or directory username@host:~$ cat proper/file-2.txt cat: proper/file-2.txt: No such file or directory username@host:~$ # Check that actual files do in fact exist username@host:~$ cat actual/file-1.txt file 1 username@host:~$ cat actual/file-2.txt file 2 username@host:~$ # Remove the links and go home :( username@host:~$ rm proper/file-1.txt username@host:~$ rm proper/file-2.txt I thought that a symbolic link was supposed to operate transparently, in the sense that you could operate on the file that it points to as if you were accessing the file directly (except of course in the case of rm where of course the link is simply removed).

• I had a power outage. Now MySQL's lock file won't go away. What do you suggest?

  - by jasonspiro

  I do freelance IT consulting for various clients, both in Toronto, Canada, and worldwide. A client recently experienced a power failure. Now they've been having various problems with a Slackware 12.0.0 machine which also acts as a DNS server. One problem is that they can't log into phpMyAdmin. I tried stopping and restarting MySQL.

• Programmatically add/delete users in Exchange

  - by Terry Gamble

  I've got the following set up: ASP.Net site that allows my internal employees to add in new hire information (no secure data, just stuff like name/address/phone) and when they submit this it goes into a database (SQL). Every few minutes a service runs that checks the database and if there are new entries it will add them into Exchange. The issue is I'm not happy with the way the service is doing things, (It's not putting address, etc in it). As I don't have the source code this I'm thinking of recreating it. My issue though is finding a starting point even. I know I'll have to create the scripts through code where the data is retrieved from SQL : Joe Smith 123 Main Street Nowhere, USA 19999 And put that into a powershell cmdlet (not sure exactly the syntax but I can get that figured out unless someone already has it) where the user is created in the Active Directory as a normal user and the mailbox is created simultaneously. From there I just need to fill out fields in Active Directory with the person's address, etc. Finally a deletion routine for when we terminate someone, however I'm sure that it will simply be a cmdlet that is easily shelled out to much like the initial one is, once I can figure out how to start that... Anyone have some good reference points or have already done it and can share?

• Win7 Domain User Profile- Desktop Icon management best practices request

  - by Doltknuckle

  Here's the situation: We have a large (5,000+ user) organization that is currently using folder redirection to manage the windows desktop icons. This folder is redirected to a network share where we can centrally manage the different sites and such. When a user tries to use a computer when the network is not available, they are unable to use any shortcuts in the Public folder. We only redirect the C:\Users\%username%\Desktop folder. Does anyone have any suggestions of how to go about managing desktop icons? We still want a central location to manage these items, but find a way to keep the system working when the network is unavailable. As a point of clarification, the network rarely goes down. We do have instances where a few computers do not have a network connection. Usually, something is simply unplugged. Since we have multiple sites, the line from a branch to the central office has gone down a few times. This is more of an attempt to maintain a positive end user experience when disconnected from the network.

• Group Policy installation failed error 1274

  - by David Thomas Garcia

  I'm trying to deploy an MSI via the Group Policy in Active Directory. But these are the errors I'm getting in the System event log after logging in: The assignment of application XStandard from policy install failed. The error was : %%1274 The removal of the assignment of application XStandard from policy install failed. The error was : %%2 Failed to apply changes to software installation settings. The installation of software deployed through Group Policy for this user has been delayed until the next logon because the changes must be applied before the user logon. The error was : %%1274 The Group Policy Client Side Extension Software Installation was unable to apply one or more settings because the changes must be processed before system startup or user logon. The system will wait for Group Policy processing to finish completely before the next startup or logon for this user, and this may result in slow startup and boot performance. When I reboot and log in again I simply get the same messages about needing to perform the update before the next logon. I'm on a Windows Vista 32-bit laptop. I'm rather new to deploying via group policy so what other information would be helpful in determining the issue? I tried a different MSI with the same results. I'm able to install the MSI using the command line and msiexec when logged into the computer, so I know the MSI is working ok at least.

• Least CPU intensive way of streaming your screen on windows?

  - by sinni800

  Hello, sometimes I like capturing my screen for others to see. Only thing: I am playing games while I do it. I have tried a few streaming solutions where Windows Media Encoder coupled with my own Windows server appealed to me most, because I can change resolutions, etc. I also tried ustream coupled with the Flash applet and the Adobe Flash Encoder recording a Camtasia source. Camtasia has the disadvantage though that it shows the green-and-black-alternating borders and can not be targeted fullscreen. I like how xfire does it. But it doesn't work with every game, many are simply not supported. A few thoughts about this: Is there a program which captures like Fraps or XFire (based on Direct3D and OpenGL outputs) and exposes the output to a DirectShow source filter? Which brings me to: Is there hardware accelerated capturing directly from the graphics card? Maybe including direct encoding with help from OpenCL? Modern graphic cards decode BluRay content directly for example. I should have a modern enough graphics processor for this to be possible (see below). If using Windows Media Encoder: Which are the least CPU intensive settings? Which codec? Is there a newer codec than Windows Media 9? Is it less CPU intensive? I only have 7, 8 and 9 inside the Encoder Could the performance be massively increased by having a Quad-Core CPU (see below)? Bandwidth is no problem up to 1000 to 1500 kbit/s (I have 2048).

Is there maybe a better way to do this and I'm just overthinking it? # /etc/puppet/modules/users/virtual.pp class user::virtual { @user { "user": home => "/home/user", ensure => "present", groups => ["root","wheel"], uid => "8001", password => "SCRAMBLED", comment => "User", shell => "/bin/bash", managehome => "true", } # /etc/puppet/modules/users/manifests/ssh_authorized_keys.pp ssh_authorized_key { "user": ensure => "present", type => "ssh-dss", key => "AAAAB....", user => "user", } # /etc/puppet/modules/users/init.pp import "users.pp" import "ssh_authorized_keys.pp" class user::ops inherits user::virtual { realize( User["user"], ) } # /etc/puppet/manifests/modules.pp import "sudo" import "users" # /etc/puppet/manifests/nodes.pp node basenode { include sudo } node 'testbox' inherits basenode { include user::ops } # /etc/puppet/manifests/site.pp import "modules" import "nodes" # The filebucket option allows for file backups to the server filebucket { main: server => 'puppet' } # Set global defaults - including backing up all files to the main filebucket and adds a global path File { backup => main } Exec { path => "/usr/bin:/usr/sbin/:/bin:/sbin" }

• SQL transaction log backups conflicting with full backups?

  - by BradC

  On our SQL servers (2000, 2005, and 2008), we run full backups once a day in the evening, and transaction log backups every 2 hrs. We haven't really worried about these two processes conflicting, but lately we've run into some of the following issues: On one server, the trans log backup occasionally blocks the full backup, and must be manually stopped before the full backup can complete We sometimes end up with a massively-sized trans log backup file (sometimes larger than the full backup!) that seems to occur at the same time the full backup is running. I found a reference that indicate that these are "not allowed" to run at the same time, whatever that means: SQL 2000 Books Online and SQL 2005 Books Online. I'm not sure whether that means that the server will simply prevent them from running simultaneously, or if we ought to be explicitly stopping the log backups while the full backups are running. So are there known conflicts/issues between these? Does the answer differ between SQL versions? Should I have the trans log backup job check to see if the full backup is running before it executes? (and how do I do that...?)

• Safely removing my linux dual boot

  - by de1337ed

  Currently, I dual boot with win7 and opensuse 12.1. Is it okay if I first restore the MBR for win7, and then format the linux drives? Or would it be better for me to first format the linux drives, and then restore the MBR? The reason I ask this is sometimes I get nasty errors when I try and boot into my win7 cd in the latter method. Is it possible to restore the MBR without having to boot into the win7 cd? Like, can I remove linux using the disk management utility in win7, and then fix the mbr while I'm still in win7, or do I have to boot into the win7 cd? If I can do this, how do I go about doing so? Thank you. EDIT::::: The spamming of f8 didn't work, it just made loud beeping noises, so I decided to simply boot into my windows disk and use the bootsect /nt60 SYS /mbr command. Note: I haven't formatted my linux partition yet. After I did that, I restarted my computer, and nothing happened. Basically, GRUB is still the MBR and I'm still able to access openSUSE. I think the reason why this is happening is because I think my GRUB is on a separate partion than the linux OS. Here is a picture of my diskmgmt in win7: . openSUSE did all the partioning stuff for me. All I know is that the 40gb that is there is where openSUSE is installed, but I have no clue what's on the 6.05gb and the 14.75gb partitions. Can anyone help me find which partition GRUB is on, and then remove it so I can restore the windows MBR? Thank you.

• IIS 404 custom error

  - by Greg B

  I've deployed an ASP.NET 3.5 app to a 64bit Windows 2003 R2 server. In the web.config I have the following <customErrors mode="RemoteOnly" defaultRedirect="/404/"> <error statusCode="404" redirect="/404/"/> <error statusCode="500" redirect="/500/"/> </customErrors> In the website properties in IIS Manager I have set the 404 and 500 errors to Type = "URL" and the same URLs as in the web.config. I have a wildcard application map to the .NET 2.0 aspnet_isapi.dll with "Verify file exists" turned off. If I try to hit a fake .aspx file I successfully get sent to the 404 page. I belive this is because there is an explicit mapping for .aspx to the .NET DLL. If I try to access a fake directory I simply recieve a plain text response saying: The system cannot find the file specified. It would appear that these requests for directories are not being routed through the .NET pipeline, which is what I would expect (and need) to happen becuase of the wildcard application mapping. Any ideas?

• Cisco ASA5505 won't sync with NTP

  - by Martijn Heemels

  Today I noticed that the clock my Cisco ASA 5505 firewall was running about 15 minutes late, which surprised me since I've set up the NTP client. My two NTP servers 10.10.0.1 and 10.10.0.2 are virtualized Windows Server 2008 R2 domain controllers, and both have the correct time. As shown below, the ASA knows about the two servers, can ping them and seems to poll them periodically, so I suppose it can reach them both. The ASA claims its time source is NTP, however the clock is unsynchronized. Neither host is marked as synced. Result of the command: "ping 10.10.0.1" Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 10.10.0.1, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms Result of the command: "sh ntp ass" address ref clock st when poll reach delay offset disp ~10.10.0.1 .LOCL. 1 78 1024 377 0.5 643.69 17.0 ~10.10.0.2 10.10.0.1 2 190 1024 377 0.9 655.91 58.4 * master (synced), # master (unsynced), + selected, - candidate, ~ configured Result of the command: "sh ntp stat" Clock is unsynchronized, stratum 16, no reference clock nominal freq is 99.9984 Hz, actual freq is 99.9984 Hz, precision is 2**6 reference time is 00000000.00000000 (07:28:16.000 CEST Thu Feb 7 2036) clock offset is 0.0000 msec, root delay is 0.00 msec root dispersion is 0.00 msec, peer dispersion is 0.00 msec Result of the command: "sh clock detail" 10:33:23.769 CEDT Tue Jun 26 2012 Time source is NTP UTC time is: 08:33:23 UTC Tue Jun 26 2012 Summer time starts 02:00:00 CEST Sun Mar 25 2012 Summer time ends 03:00:00 CEDT Sun Oct 28 2012 I've tried the basic steps of manually setting the time and removing and adding the timeservers, to no avail. My ASA's ntp config is simply: ntp server 10.10.0.1 ntp server 10.10.0.2 Do I need to enable authentication to use a Windows NTP server? Any thoughts?
