• Recommendations for good Unix MTA / groupware solutions? [closed]

  - by Jez

  Possible Duplicate: Exchange server replacement that runs on Linux I'm setting up a Debian server, and one of the things I need on it is an MTA. I don't want to use something like Exim or Postfix because I want something that ties in SMTP, POP3, and IMAP all in one (a la Microsoft Exchange). Most MTAs also seem to be hellishly difficult to configure. Try and read the Exim documentation; you could do a university degree on it (I'm not kidding). When you can get an HTTP server like Cherokee which is easy to configure and has a nice web interface, do MTAs or groupware solutions need to be that hard? I'm aware that some people think "the Unix way" is to have lots of different interacting pieces of software (like maybe an SMTP MTA, POP3 service, webmail service, and overarching manager to tie them all together), but I think this is a situation where that just makes things a lot harder to deal with and one large software suite fits in much more nicely. So, I'm looking for good open source software suites that will run on Debian that: Combine (at least) SMTP, POP3, and IMAP Are easy(ish) to configure Have a nice configuration web interface or GUI Are not defunct projects I don't mind if it's groupware and offers calendaring too, but I would only be using the e-mail functionality for now. Another nice-to-have would be built-in webmail (if we're combining a bunch of functionality, why not?) Note however that I do NOT need Outlook support. I am not really looking for an "Exchange replacement drop-in". The suites I've found so far that seem to match the above criteria (and have appropriate licenses) are Citadel, Kolab, and Zimbra. I'd appreciate anyone who has experience with any of these giving me the pros and cons of them, such as how easy they are to configure and what their performance is like. I'd also appreciate any other suggestions for solutions that fulfil my criteria that I may have missed out.

• Servers - Buying New vs Buying Second-hand

  - by Django Reinhardt

  We're currently in the process of adding additional servers to our website. We have a pretty simple topology planned: A Firewall/Router Server infront of a Web Application Server and Database Server. Here's a simple (and technically incorrect) diagram that I used in a previous question to illustrate what I mean: We're now wondering about the specs of our two new machines (the Web App and Firewall servers) and whether we can get away with buying a couple of old servers. (Note: Both machines will be running Windows Server 2008 R2.) We're not too concerned about our Firewall/Router server as we're pretty sure it won't be taxed too heavily, but we are interested in our Web App server. I realise that answering this type of question is really difficult without a ton of specifics on users, bandwidth, concurrent sessions, etc, etc., so I just want to focus on the general wisdom on buying old versus new. I had originally specced a new Dell PowerEdge R300 (1U Rack) for our company. In short, because we're going to be caching as much data as possible, I focussed on Processor Speed and Memory: Quad-Core Intel Xeon X3323 2.5Ghz (2x3M Cache) 1333Mhz FSB 16GB DDR2 667Mhz But when I was looking for a cheap second-hand machine for our Firewall/Router, I came across several machines that made our engineer ask a very reasonable question: If we stuck a boat load of RAM in this thing, wouldn't it do for the Web App Server and save us a ton of money in the process? For example, what about a second-hand machine with the following specs: 2x Dual-Core AMD Opteron 2218 2.6Ghz (2MB Cache) 1000Mhz HT 16GB DDR2 667Mhz Would it really be comparable with the more expensive (new) server above? Our engineer postulated that the reason companies upgrade their servers to newer processors is often because they want to reduce their power costs, and that a 2.6Ghz processor was still a 2.6Ghz processor, no matter when it was made. Benchmarks on various sites don't really support this theory, but I was wondering what server admin thought. Thanks for any advice.

• Microsoft Deployment Toolkit 2012 Error

  - by Jacob Schaer

  I just started with MDT2012 recently in hopes of eventually getting away with using Ghost to deploy all of our department computers. When I test deploy in VirtualBox, it deploys the OS properly, but stops because of a network driver failure (it gets the "could not allocate resources" issue). On physical hardware (Latitude E6500, Optiplex 980, and an older Latitude) it gets through the multicast and stops immediately after with: "Setup was unable to create a new system partition or locate an existing system partition. See the Setup log files for more information" I've looked at the logs and never see anything really of note. Originally I was using DriverPacks from DriverPacks.net, but thinking it was a driver issue, I switched over to using Dell's cab driver packs. Still the same issue. I check and it did the HDD is all fine - it was properly partitioned, set to bootable, and was loaded with all the proper OS installer files. I'm using a flash drive to do the install - when I make changes to the deployment share I rebuild and copy the ISO to the drive, then use YUMI multiboot to start the ISO (probably irrelevant).

• Finding bluetooth link key in Win7, to double pair a device on dualboot computer

  - by Ilari Kajaste

  How can I dig up the bluetooth link key for a paired device in Win7? Is this something that is dependent on the bluetooth stack I'm using (Toshiba), or is there a generic place to store these in Win7? Note: I'm not talking about the six-digit code usually typed by the user during pairing - that is worthless since it's discarded after pairing process. What I mean is the 128-bit link key that the devices exchange during pairing, and use thereafter to encrypt all their bluetooth traffic. Background: I dualboot Win7 / Ubuntu on my laptop, and I would like to have my phone paired to both OS's. Since the dualbooting computer has only one bluetooth adapter and thus only one bluetooth address, I cannot do two pairings to the phone, since on the second pairing (windows) the phone just replaces the previous pairing (linux) to the same bluetooth address. A thread on Ubuntu forums pointed me to what I have to do - pair first on linux, then on windows, and then replace the link key on linux side with the one windows negotiated. I can find the linux side pairing key from /var/lib/bluetooth/[BD_ADDR]/linkkeys - no problems there. However, on windows side I can't find the key. According to the forum post, on windows side the key should be in SYSTEM\ControlSet002\services\BTHPORT\Parameters\Keys\[BD_ADDR] but while that registry key does exist, it has no subkeys. (And a similar registry path in ControlSet001 didn't have any subkeys either.) One thing I've been instructed to do is to capture all events during pairing with Sysinternals Process Monitor. I did this, but I haven't been able to find any useful information from the captured events, not even by exporting the data to a huge XML and grepping that with the BD_ADDRs (with or without colons). So how could I find the link key for a paired device in Win7? Some reference information: Wikipedia: Bluetooth, Security Now: Bluetooth security

• Separate Certificate by Subdomain (With multiple IPs)

  - by Brian

  Note: Yes, I realize this problem is easier to solve by just using 1 multi-domain or wildcard certificate. I wish to have an ASP.NET site running on IIS with 2 SSL domains sharing 1 web application but using separate certificates. Assuming I have 2 certificates, this can be solved on IIS7 as follows: Web Application1: Binding 1: http, 80, IP Address *, Host Name * Binding 2: https, 443, IPADDRESS1, using CERTDOMAIN1 (DOMAIN1 resolves to IPADDRESS1) Binding 3: https, 443, IPADDRESS2, using CERTDOMAIN2 (DOMAIN2 resolves to IPADDRESS2) That is to say, 2 certificates and 2 ip addresses, but both mapped to the same web application. In IIS6, the closest I have been able to come to this configuration is: Web Application1: Binding 1: http, 80, IPADDRESS1 Binding 2: https, 443, IPADDRESS1, using CERTDOMAIN1 (DOMAIN1 resolves to IPADDRESS1) Web Application2: Binding 1: http, 80, IPADDRESS2 Binding 2: https, 443, IPADDRESS2, using CERTDOMAIN2 (DOMAIN2 resolves to IPADDRESS2) That is to say, 2 certificates and 2 IP addresses, 2 web applications, both mapped to the same file location. The IIS6 solution is not optimal. Even if sharing an application pool, there are still costs associated with running the same site as two applications. Is upgrading from IIS6 to IIS7 a legitimate way to resolve this problem? Is there an IIS6 way to map 2 IP addresses within the same web application to different certificates?

• How to find the IP Address of a vm running on VMware (or other methods of using VM)

  - by sixtyfootersdude

  I am running VMware Workstation on a Linux box. When I power on a centOS (Linux) virtual machine I cannot get mouse or keyboard control of the machine. I suspect that it has something to do with the error message: You do not have VMware Tools installed in this guest. Chose "Install VMware Tools" from the VM menu. If I click on that menu option it inserts a virtual cd with drivers etc. This does not help me since I don't have keyboard or mouse control over the machine. I was thinking that if I could figure out the IP address or hostname I could use any number of protocols to get into the machine (SSH comes to mind). How can I get the IP address or hostname of this machine? Note: I did not create this machine. A coworker created it who is no longer with the company. Would save me a lot of time if I could get into the machine. I have login credentials so that won't be a problem.

• Grub rescue, unknown file system. Can't boot into Windows 7

  - by Sam J

  So, I'm confused, so I'm also going to use this question to get clarification and fix my computer. So, some background: I had Windows 7 on a 1 TB HDD and decided to partition my hard drive into two ~500 GB, one for Windows 7 and one for Ubuntu or whatever flavour I desired (like a sandbox partition...) I installed Ubuntu but the installation had issues so I decided to uninstall. Note before uninstallation I had to press f12 when I turned on to boot from my primary HDD, then choose what OS I wanted to use. Undesirable, but it worked. Anyway, after I decided to uninstall Ubuntu I went into Windows 7 Start Computer Manage and deleted the EXT4 filesystem (Ubuntu parition) giving me 4xx GB of free space. However when I restarted Windows 7, I am now unable to boot Windows. When I DON'T hit f12, I see a blank screen with a flashing underscore. When I DO hit f12, I choose my primary HDD, and then I get a GRUB error: Unknown filesystem: grub rescue _ Something I'm unclear of: GRUB boots linux partitions, right? What boots Windows? Is GRUB "overwriting" the Windows bootloader? How can I completely get Windows back to normal? (IE, It boots automatically without hitting f12.) Thanks for any help, I'm on a live CD version of Ubuntu right now until I can get back on Windows.

• What does SQL Server's BACKUPIO wait type mean?

  - by solublefish

  I'm using Sql Server 2008 ("R1"), with some maintenance plans that back up my databases to a network share. Some of my backup jobs show long waits of type "BACKUPIO". Of course it seems like this is an I/O subsystem limitation, but I'm skeptical. Perfmon stats for I/O on the production (source) server are well within normal trends for that server. The destination server shows a sustained 7MB/s write rate, which seems incredibly low, even for a slow disk. The network link is gigabit ethernet and nowhere near saturated. The few docs I've turned up about BACKUPIO indicate that it's not specifically a wait on I/O, surprisingly enough. This MSFT doc says it's abnormal unless you're using a tape drive, which I'm not. But it doesn't say (or I don't understand) exactly what resource is missing. http://www.docstoc.com/docs/24580659/Performance-Tuning-in-SQL-Server-2005 And this piece says it's not related to I/O performance at all. http://www.informit.com/articles/article.aspx?p=686168&seqNum=5 "Note that BACKUPIO and IO_AUDIT_MUTEX are not related to IO performance." Anyway, does anyone know what BACKUPIO actually means and/or what I can do to diagnose or eliminate it?

• How to restore Active Desktop if Themes is locked via GPO?

  - by pepoluan

  My company forces Active Desktop upon everybody so that it can display a (monthly-rotated) corporate wallpaper.jpg. Problem is, some computers (including my laptop) somehow experienced some errors resulting in the dreaded "Active Desktop Recovery" screen to show up... and clicking the "Restore My Active Desktop" button always resulted in "Internet Explorer Script Error". Various workarounds I found in the Internet either does not work or requires me to change the theme first to something else... and the latter I can't do because the Desktop Settings screen is locked via GPO. As it happens, due to the nature of the programs I use, I'm granted Administrator-level access on my computer. The question is: How do I fix my situation? Note: I don't need to put on my own wallpaper, but watching the "Active Desktop Recovery" screen (with its BLANK WHITE!!1! OH MY EYES!1!!one!eleven!! background) gets tiresome. I'm quite happy with the corporate wallpaper. I just need to somehow 'recover' my Active Desktop. More information: OS: Windows XP Professional SP3 (yeah, company's too afraid to even experiment with Windows 7) Antivirus: Symantec Endpoint Protection If you need any additional information, feel free to ask.

• Every month, scheduled task fails and password must be reset - why?

  - by Ducain

  [NOTE: I posted this originally at StackOverflow but it got no traction there - reposting here.] We have a bit of software installed at a few client locations that runs (via Windows task scheduler) a few times each day. In ONLY ONE of the client locations, we have a unique problem: each month, the task will stop working, after running every day for weeks. Twice now it's failed on the 2nd of the month. When I walk the client through troubleshooting it, we've found that it can't start - access denied. To fix it, we simply re-enter the same exact password, and then off it goes happy as a clam. I've never heard of this issue, and their IT people say they don't have anything running once a month that might cause that. I'm at a complete loss here. Any ideas as to why this might be happening? Further details: Windows XP pro machine. Task is being fired with credentials from a local admin account. Computer is always on, and connected to the net.

• How to set up Windows 7 Professional as a NAS

  - by Enyalius

  I searched and didn't find any answers, so please forgive me if this is a repeat. Anyway, I have an older computer that I'm using as an HTPC, and I was hoping that I could use it as a NAS/multimedia server, as well. My primary uses would include accessing content on my PS3 (same LAN), accessing content from other computers on my home network and (if I can) accessing content from my Android phone over the internet. I have used SubSonic to stream music to my Android phone and other computers before, but I would really like to find a way to do this natively if possible. I know that I can buy external hard disk cases that can plug in the USB port of my router, that I can get a Drobo or other network storage solution, but I would really just rather not spend the money (especially considering that I already have a computer that I should be able to use). Hardware involved: Apple AirPort Extreme base station router (most recent revision) Home Theater Personal Computer: Core 2 Duo @ 2.4GHz, 8GB DDR2 RAM, ~3.5TB hard drive space Sony Playstaiton 3 Thin 120GB HTC Thunderbolt (I have 4G coverage) rooted and running Android 2.2.1 Various Apple laptops Various Windows 7 desktops/laptops Thanks in advance! Note- I have looked at open source NAS software but I would like to preserve the Windows Media Center functionality in Windows 7, so other NAS software is not an option for me currently. .

• WIN7 constant BSOD 0x7B on boot, not producing any dump files where to go from here?

  - by prayingpantis

  So my one win 7 pc has been getting a BSOD on boot (roughly a sec after load screen starts) after a power failure. The complete stop code is 0x0000007B (0x80786B58, 0xC0000034,0x00000000,0x00000000) I've searched for quite a while now on the net and it seems like most people gave up after gettting 0x7B and no dump files. What I've tried so far: startup repair - reports it cannot repair computer automatically. BadPatch is reported somewhere in a problem signature contained in the problem details. startup repair with a WIN 7 CD - also fails, I can't recall what the error was, but it was not the same as the error produced with the start up tool shipped with the version of WIN 7 installed on my machine (I think the text had something ACL-ish contained in it) used a boot disk (Hiren's boot iso) - I used it to enable the CrashDump registry key and then after BSOD, read the HDD's dump locations but it was empty. Note, I'm quite sure the registry keys I edited are the correct ones, since the reboot on BSOD option was enabled by default and after I changed the regkey controlling this functionalitty to 0 the BSOD stayed after I booted again. check disk - works and returns no problems, also it seems I'm able to access all my files on the HDD. mem test - works and returns no errors So I'm not sure what else I can do to figure out what is the problem here. I read somewhere that you can use WINDBG to remote debug another PC, but I'm not sure if this is possible since the OS isn't even loaded yet? Also the last driver change I made on the system was installing a video driver, but I had no problems with it and were able to reboot several times until the power outage happened and the BSOD appeared. Any help or guidance for a way to DEBUG this problem would really be appreciated (I'm not really that keen to try a whole bunch of random fixes, I'd rather try and narrow down the problem first).

• Cloning a failing disk (Win 7)

  - by daveh551

  I have a Windows 7 machine with several partitions on a 1.5T drive. Windows has been complaining about disk errors and imminent failure, so I have purchased a new 2TB drive. The failing disk has not completely failed, and, in fact, I was able to boot Windows from it (after a couple tries) and examine the SMART logs - the only RED item was 1 sector being reallocated. But when I try to Clone it to the new Drive using Acronis True Image Home (2010), True Image can see the drive, the partitions, and the contents, but when it goes to actually do the clone, it says "Failed to move. Make sure the destination disk is not smaller than the source disk, and that there are not errors on the disk" (or something like that). What are some other options for simply cloning the failing drive. I'd like to clone the entire disk, but am willing to do it partition by partition if necessary. Was this a known failing of the 2010 edition of ATI, or is it really something hosed in my system. Would upgrading to the 2012 edition be likely to work any better? (I'd download the trial and try it out, but if I remember right, the cloning operation is disabled in the trial version), and I don't have enough free disk space to make an entire image.) What are some other cloning software packages if ATI won't work? Note that I'm only looking to clone the disk, not make an image as a back up - I use Ghost for that, and can fall back to that if I have to. It looks to me like CloneZilla would do the job. Any recommendations? Thanks, and if this duplicates other questions, I apologize.

• Hyper-V vss-writer not making current copies [migrated]

  - by Martinnj

  I'm using diskshadow to backup live Hyper-V machines on a Windows 2008 server. The backup consists of 3 scripts, the first will create the shadow copies and expose them, the second uses robocopy to copy them to a remote location and the third unexposes the shadow copies again. The first script – the one that runs correctly but fails to do what it's supposed to: # DiskShadow script file to backup VM from a Hyper-V host # First, delete any shadow copies of the drives. System Drives needs to be included. Delete Shadows volume C: Delete Shadows volume D: Delete Shadows volume E: #Ensure that shadow copies will persist after DiskShadow has run set context persistent # make sure the path already exists set verbose on begin backup add volume D: alias VirtualDisk add volume C: alias SystemDrive # verify the "Microsoft Hyper-V VSS Writer" writer will be included in the snapshot # NOTE: The writer GUID is exclusive for this install/machine, must be changed on other machines! writer verify {66841cd4-6ded-4f4b-8f17-fd23f8ddc3de} create end backup # Backup is exposed as drive X: make sure your drive letter X is not in use Expose %VirtualDisk% X: Exit The next is just a robocopy and then an unexpose. Now, when I run the above script, I get no errors from it, except that the "BITS" writer has been excluded because none of its components are included. That's okay because I really only need the Hyper-V writer. Also I double checked the GUID for the writer, it's correct. During the time when the Hyper-V writer becomes active, 2 things will happen on the guest machines: The Debian/Linux machine will go to a saved state and restore when done, all fine. The Windows guests will "creating vss snapshop-sets" or something similar. Then X: gets exposed and I can copy the .vhd files over. The problem is, for some reason, the VHD files I get over seems to be old copies, they miss files, users and updates that are on the actual machines. I also tried putting the machines in a saved sate manually, didn't change the outcome. I hope someone here has an idea of how to solve this.

• nginx codeigniter rewrite: Controller name conflicts with directory

  - by palerdot

  I'm trying out nginx and porting my existing apache configuration to nginx. I have managed to reroute the codeigniter url's successfully, but I'm having a problem with one particular controller whose name coincides with a directory in site root. I managed to make my codeigniter url's work as it did in Apache except that, I have a particular url say http://localhost/hello which coincides with a hello directory in site root. Apache had no problem with this. But nginx routes to this directory instead of the controller. My reroute structure is as follows http://host_name/incoming_url => http://host_name/index.php/incoming_url All the codeigniter files are in site root. My nginx configuration (relevant parts) location / { # First attempt to serve request as file, then # as directory, then fall back to index.html index index.php index.html index.htm; try_files $uri $uri/ /index.php/$request_uri; #apache rewrite rule conversion if (!-e $request_filename){ rewrite ^(.*)/?$ /index.php?/$1 last; } # Uncomment to enable naxsi on this location # include /etc/nginx/naxsi.rules } location ~ \.php.*$ { fastcgi_split_path_info ^(.+\.php)(/.+)$; # NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini # With php5-cgi alone: fastcgi_pass 127.0.0.1:9000; # With php5-fpm: #fastcgi_pass unix:/var/run/php5-fpm.sock; fastcgi_index index.php; include fastcgi_params; } I'm new to nginx and I need help in figuring out this directory conflict with the Controller name. I figured this configuration from various sources in the web, and any better way of writing my configuration is greatly appreciated.

• LighTPD and PHP not working if outside of LightTPD folder

  - by Marco83

  I need to set up a simple web server with PHP on Windows XP that a number of different people will use for local testing. I'm using LightTPD 1.4.30-4-IPv6-Win32-SSL and PHP 5.2. So far I've created this folder structure: tools/ LightTPD/ htdocs/ PHP/ I set up PHP as CGI and the document root as server_root + "/htdocs". It works fine (well, it's slow but I don't want to bother with FastCGI for now :) ). My problem is when I try to put the htdocs outside of LightTPD folder, like this: htdocs/ tools/ LightTPD/ PHP/ I update the document root to server_root + "/../../htdocs" and while static HTML pages work fine, PHP pages stop working (they return a "No input file specified"). I literally just change the document root, I didn't change anything in the php.ini or anywhere else. Please also note that I left all doc_root, user_dir and cgi.force_redirect to the default values in php.ini, and it works when htdocs is inside LightTPD, but not when I move it ouside. Any idea of why it's breaking?? Here's my lightTPD.conf: server.modules = ( "mod_access", "mod_accesslog", "mod_alias", "mod_cgi", "mod_status", ) include "variables.conf" include "mimetype.conf" # THIS WORKS server.document-root = server_root + "/htdocs" # THIS DOESN'T #server.document-root = server_root + "/../../htdocs" server.upload-dirs = ( temp_dir ) index-file.names = ( "index.php", "index.pl", "index.cgi", "index.cml", "index.html", "index.htm", "default.htm" ) server.event-handler = "libev" url.access-deny = ( "~", ".inc" ) $HTTP["url"] =~ "\.pdf$" { server.range-requests = "disable" } static-file.exclude-extensions = ( ".php", ".pl", ".cgi" ) server.errorlog = server_root + "/logs/error.log" ######### Options that are good to be but not neccesary to be changed ####### dir-listing.activate = "enable" #### CGI module cgi.assign = ( ".php" => server_root + "/../PHP/php-cgi.exe" ) status.status-url = "/server-status" status.config-url = "/server-config"

• Import data in Excel that doesn't have a row delimiter, but number of columns is known

  - by Alex B

  So i have this text file that looks something like this: Header1 Header2 Header3 Header4 A1 B1 C1 D1 A2 B2 C2 D2 and so on. When imported, I'd want the data to format itself in 4 columns. I tried the Get External Data from Text, and it successfully imports it, but it doesn't wrap it around, so it just keeps making columns for every space. I'd want it to go on the next line after 4 (in this case) elements have been added. What's the simplest way to achieve this? EDIT: My answer follows, since I'm not yet allowed to answer my own questions yet. The Excel function I needed is called indirect(). Not sure how it actually works though, so hopefully someone can help out with that, but the function call that worked for me is =INDIRECT(ADDRESS((ROW(A1)-1)*4+COLUMN(A1),1)) which i found over here: http://www.ozgrid.com/forum/showthread.php?t=101584&p=456031#post456031 Note: this required me to add the text to excel where i'd get this row full of columns, and then flip it so that i'd have a column full of rows.

• Dual boot Windows 8 and Ubuntu 12.10 across a reboot

  - by AK4749

  My Setup: I have two separate SSDs, and each contains an independently bootable OS - W8 and U12.10. From my extremely limited knowledge, this means each has a functioning EFI partition(?). My default boot order (GA-Z68XP-UD3P mobo with UEFI firmware update) boots the UEFI partition containing windows first, but if I enter the BIOS I can select the "ubuntu" entry to successfully boot ubuntu. Both drives are GPT, and are EFI boots. What I want to do: Reboot Windows 8, re-enter W8 (this is happening now due to the default boot order). What I want to change, however, is to boot into Ubuntu if i reboot from ubuntu. Essentially, I would like to work within one OS unless I consciously choose otherwise. Normally, I would not even ask to something I thought was impossible, but... Why I think this is possible: When trying EasyBCD to add ubuntu to the W8 UEFI bootloader, I noticed an "iReboot" addon or something that allows you to select which OS to boot into from within the OS. Note that I ended up not using the NeoGrub entry to chain Ubuntu off the W8 bootloader because I couldn't get much help with it. Is this possible? Have I had too much coffee and gone insane? Thank you all for your time, AK

• As an admin, what tools do you use to log what you do to your boxes?

  - by Jerry

  I am more of a linux applications developer than an admin. Over time, I've built servers and maintained them, sometimes to offer services, mostly just to develop the applications I work on. Way back when I would create a file in my account to keep notes on what I did on each machine, so that I could replicate that when I migrated to other machines. Nowadays, I install something a private trac installation, install it's blog plugin, and then use that to make notes of everything I install, and most commands that I run, as well as the output. This provides me a combination wiki and blog that I find very useful as a "captain's log". I do this mostly so that when I migrate to a new clean machine, I have a much easier time in bringing it up. And yet, I am always amazed when I see others just install this, delete that, run this, setup this config, ... without seeming to use any way to actually note what they are doing. What do YOU do, and what tools are available? I am especially interested in the transition between maintaining a few machines for a few people and maintaining several to dozens of machines providing a real service. What are the best practices, and where can I find good resources? Thanks!

• Can a non-redundant RAID5 cause any serious problems (compared to RAID0)?

  - by leemes

  I used to have a three-disc RAID5 (mdadm) in my computer for personal media storage (music, videos, photos, programs, games, ...). It had three discs with 750 GB each, resulting in an array capacity of 1.5 TB. One day (one year ago), I needed one of those discs to install another operating system. I thought, I don't need the redundancy anymore since I backup the most important stuff (personal photos e.g.) on an external disc anyway. So I decided to remove one of the three discs without converting the RAID to RAID0 or even two separate discs, because I had no temporary storage (since one cannot simply convert the RAID5 to RAID0 AFAIK). So now, for about one year, I have a non-redundant RAID5 with 2 of 3 discs running. Sometimes, one of the discs has a defective contact at the power cable or something similar causing the drive to stop working temporarily (I don't know exactly what it is). Since it still works when rebooting the computer and in most cases by calling some mdadm commands, it wasn't that problematic. Note that the data is not very critical, since I still have a backup of the most important stuff. But in the last few weeks, one of the drives fails very frequently (every few hours), so it gets really annoying to manage this. My questions are: Is there any disadvantage (apart from the annoying management) of a non-redundant RAID5 (with one drive less than typical) over a RAID0? If I understand it correctly, both have no redundancy and the same capacity. On a temporary drive failure, I can restart the array in both cases, assuming that the drive itself still works after the failure. Can it happen that the drive contents alter on a drive failure, making the array inconsistent? If so, can I tell mdadm to check the array for failures (without a file system level checking tool)? Since the drive most probably only has a defective contact causing it to fail for a second only, can I tell mdadm to automatically restart the array, so I will not even notice the failure if no application wanted to access the file system during the failure?

• Excel table auto update

  - by Mike

  So I have a table in Excel with formulas. When I add a new row, the new row automatically fills in the formulas as well, which is great. My problem is that it also changes the formula in the row above the added row as well. Here's what happens specifically: My table's last row is row 24. A formula I have in that row is the following: =COUNTIF(C$11:C24,"y")/(COUNTIF(C$11:C24,"Y")+COUNTIF(C$11:C24,"N")) When I add in data in row 25 the formula is updated in row 25 as well, which is what I want, to the following: =COUNTIF(C$11:C25,"y")/(COUNTIF(C$11:C25,"Y")+COUNTIF(C$11:C25,"N")) My problem is that the row above also updates - my row 24 changes to the same as row 25 (the C24 goes to C25). Why is my row 24 formula changing when I add a row 25? Note, my formulas above row 24 stay the same when I add in row 25 - only row 24 changes when I add in 25. Is there a way to not update the row above the row being added? This problem continues when additional rows are added - If I add in a row 26, then the formula in rows 24-26 then all reference C26. Why are they all updating?

• S3sync not working

  - by user57833

  Hello, I managed to get s3sync to upload my test folder to Amazon S3 and can see it in the MWS Managment Console. Downloading the data back to a test folder results in the following error message: root@mybucketname:/var/s3sync# ./week_download.sh s3Prefix backups/weekly localPrefix /var/s3sync/testdown/weekly s3TreeRecurse mybucketname backups/weekly Creating new connection Trying command list_bucket mybucketname prefix backups/weekly max-keys 200 delimiter / with 100 retries le ft Response code: 200 prefix found: / s3TreeRecurse mybucketname backups/weekly / Trying command list_bucket mybucketname prefix backups/weekly/ max-keys 200 delimiter / with 100 retries l eft Response code: 200 S3 item backups/weekly/ s3 node object init.

Does the download script need to download to the source of Amazon S3 i.e testup folder? Was hoping on the instance of a complete failure and the original folders won't exist that it would just download everything from me. Note: changed my bucket names to "mybucketname" so that it is not public!

• How to do a Windows 7 Image restore to an external drive?

  - by Vaccano

  I have a system that I have done a Windows 7 Image restore on. I would like to migrate that image to a different hard drive. Is there a way to restore the image to an externally connected hard drive? For example: I have 3 hard drives: The first in the source machine (the one I want to copy). The second in a machine that I want to do the work. And the third is not in a machine. It is the target that I want to overwrite with the contents of the first. I boot up a 2nd machine and connect the 3rd hard drive externally (using some cool cables I have). I then use some cool feature of Windows 7 to replace what is on the 3rd hard drive with the windows 7 image of my 1st machine (that is on on my networked backup server). I need to know what the above mentioned "cool feature of windows 7" is, if there is one. And how to use it. Any ideas? Note: that I very much so don't want it to overwrite what is on the 2nd machine/hard drive.

• How can I duplicate HBCD's XP boot loader with my MBR?

  - by Warpstone

  I'm stumped. I'm migrating a Win XP Lenovo T500 to an SSD: I copied the XP partition using EaseUS to the SSD. Aligned the boot sector using Gparted The MBR needs to be rebuilt (fair enough) However, all attempts to use the Windows Recovery console hang (both via a boot CD and even when the console was installed as a boot option). I've tried using a bunch of tools to rebuild/replace the MBR, but no dice. They all say the MBR has been fixed, but I cannot load Windows from the SSD. The HBCD's boot from windows option works just fine however. I'm confused as to what HBCD can do that my drive can't. How can I get that functionality on my SSD? Is it a MBR fix I can mirror? The SSD is extremely fast when I do use HBCD to boot up... but it would be nice to not need a token-based access to the machine! :) Note: I know, windows 7 may be worth a fresh install, but I'm trying to avoid the cost and hassle if possible.

• Laptop + External Monitor: Possible to Scale Mouse-crossover Position?

  - by Brian Lacy

  I have a laptop with a 16" screen @ 1366x768 resolution, and a 24" external monitor at 1920x1200 resolution. I'm extending the Windows 7 desktop onto the other screen. The 24" is the secondary monitor, and is positioned so the bottom of that screen lines up with the bottom of the 16" screen. Currently, if I move the mouse to the top portion of the 24" screen, then move left, the mouse will stop at the edge of the 24" screen until I move it down far enough to get into the range of the 16" screen. So that's all pretty standard; but I'm wondering if there's any software out there that will allow me to "scale" the mouse-crossover position, such that if I'm at the TOP of the 24" screen and move left, the mouse will cross to the TOP of the 16" screen, whereas if I'm at the BOTTOM of the 24" screen, crossing over will position the mouse at the BOTTOM of the 16" screen. So then, if the mouse cursor is on the 24" screen at (x,y) position (10,600), and I move 20 pixels left, the mouse is now on the 16" screen at position (1356,384). Anyone know of such a solution?? Note: I also use Ubuntu, so if there's a solution to this for X, but not Windows, I'd be interested in that also.
