• Dual booting Windows 7 & 8.1, using the Windows 8 Startup Options Menu, when Windows 8.1 is already installed and you want to add Windows 7

  - by Josh

  There are many excellent guides out there that explain how to dual-boot Windows 7 & 8. However, they are written for people starting with a Windows 7 installation and add a Windows 8 installation to separate partition. From what I'm reading, following this procedure will result in Windows 8 installing and configuring the Startup Options Menu with an option to boot Windows 7 & 8. However, in my situation I have a Windows 8.1 machine that I want to install Windows 7 on, and enable dual-boot, where I can use the Startup Options Menu to select the OS to boot. I haven't been able to determine how to do this. From everything I've been able to find, it looks like if I install Windows 7, it is going to take over the boot loader process, and I won't have access to the Windows 8 "Startup Options Menu." This answer suggests I boot to VHD, but notes a drawback: You can't do this if the C:\drive is encrypted using ANY encryption shceme. Be that BitLocker or 3rd party. The location of the .VHD file you are booting to must reside on an unencrypted volume. Well, that's a bummer, because that's exactly what I wanted to do--I wanted my Windows 7 partition to be encrypted, and my Windows 8 partition to also be encrypted. The idea being that when OS was booted, it was completely locked out from accessing data on the other OS's partition. At this point, I'm thinking my only option is to install Windows 7, and then re-install Windows 8, which will give me the dual-boot option... am I right? Or is there a way to make this work. I'm thinking that I would need to figure out a process like this: Configure the Windows Startup Options Menu with a "blank" entry for Windows 7, pointing to an empty partition Insert the Windows 7 installation media, install Windows 7, and somehow restrict it to that partition (i.e., prevent it from "taking over" from the Startup Options Menu" Is this possible, and if so, how can I accomplish this? My concern is that if I simply install Windows 7 to a separate partition, Windows 7 will take over the entire boot process and I won't be able to get to my Windows 8 installation any more.

• I/O intensive MySql server on Amazon AWS

  - by rhossi

  We recently moved from a traditional Data Center to cloud computing on AWS. We are developing a product in partnership with another company, and we need to create a database server for the product we'll release. I have been using Amazon Web Services for the past 3 years, but this is the first time I received a spec with this very specific hardware configuration. I know there are trade-offs and that real hardware will always be faster than virtual machines, and knowing that fact forehand, what would you recommend? 1) Amazon EC2? 2) Amazon RDS? 3) Something else? 4) Forget it baby, stick to the real hardware Here is the hardware requirements This server will be focused on I/O and MySQL for the statistics, memory size and disk space for the images hosting. Server 1 I/O The very main part on this server will be I/O processing, FusionIO cards have proven themselves extremely efficient, this is currently the best you can have in this domain. o Fusion ioDrive2 MLC 365GB (http://www.fusionio.com/load/-media-/1m66wu/docsLibrary/FIO_ioDrive2_Datasheet.pdf) CPU MySQL will use less CPU cores than Apache but it will use them very hard, the E7 family has 30M Cache L3 wichi provide boost performance : o 1x Intel E7-2870 will be ok.

• Specifying network settings during SLES 11 auto installation

  - by banjer

  I'm setting up an autoinst.xml file for auto-installing SLES 11. I get prompted for the various interface settings per below, but they don't seem to stick once the server reboots. I don't think I have the xml defined correctly. I'm hoping someone has experience with this. <ask-list> <ask> <path>networking,dns,hostname</path> <question>Enter Hostname (server name)</question> <stage>initial</stage> <default>merkin</default> </ask> <ask> <path>networking,interfaces,interface,0,device</path> <question>Enter the primary ethernet device:</question> <stage>initial</stage> <default>eth0</default> </ask> <ask> <path>networking,interfaces,interface,0,ipaddr</path> <question>Enter the primary IP Address:</question> <stage>initial</stage> </ask> <ask> <path>networking,interfaces,interface,0,netmask</path> <question>Enter the Netmask Address:</question> <stage>initial</stage> </ask> <ask> <path>networking,routing,routes,route,0,gateway</path> <question>Enter the primary Gateway Address:</question> <stage>initial</stage> </ask> </ask-list> The first one for hostname seems to be sticking just fine, but the rest do not. As an alternative, is there a way to stop the autoinstall at the section where you configure the network devices so that the user can take over? I was able to show the partition proposal, but not sure how to do the same with the networking setup.

• Best Processor for MediaSmart Server?

  I'm trying to figure out what the best possible processor is that I can stick in my HP MediaSmart server. I'm clueless when it comes to correlating CPUs to motherboards.

• Subversion - Retrieval of mergeinfo unsupported

  - by jamesthomson

  Hi, I've recently updated my Subversion package on Debian Etch to 1.5.1 via a back-port. I've gone through what I believe are all the appropriate steps but cannot for the life of me get past the following error message when I try to merge: Retrieval of mergeinfo unsupported by '.' The '.' isn't important as I get the same message whether I'm SSH'd on to the server or using TortoiseSVN through Windows. I'll take you through what I did to upgrade and test step by step: Update of Subversion Added the following line to /etc/apt/sources.list: deb http://www.backports.org/debian etch-backports main contrib non-free and then ran apt-get -s -t etch-backports install subversion Checked the version of the subversion installation Done this by running svnadmin --version and got the following output: svnadmin, version 1.5.1 (r32289) compiled Dec 11 2008, 18:10:14 Checked the client too using svn --version and got the following svn, version 1.5.1 (r32289) compiled Dec 11 2008, 18:10:14 Ok, so all looking good so far. Now I just need to upgrade the repository. After plenty of research, the most foolproof way to do this seemed to be to dump the repository and then load it again. So here's what I did: svnadmin dump /var/svn/repo > repo.dump rm -aR /var/svn/repo/* svnadmin create /var/svn/repo svnadmin load < repo.dump All that seemed to work fine. I then checked to see if the repository had been upgraded by looking at the contents of /var/svn/repo/db/format which gave: 3 layout sharded 1000 Again this indicated a Subversion 1.5 repository so all looking good. Now I try and do a merge using the Subversion client in Debian: svn mergeinfo https://mysvn/repo . and I get the following error: svn: Retrieval of mergeinfo unsupported by '.' I get the same error message whether I'm using the Debian shell on the same server or if I'm connecting via TortoiseSVN and a Windows box. If I browse to the repository using my web browser, the version number at the bottom reads: Powered by Subversion version 1.4.2 (r22196). In case it helps, the created date on mod_dav_svn.so is 2009-08-06 18:29 I just cannot figure out why I'm getting this message so any help pointing me in the right direction would be greatly appreciated. All the forum and mailing list posts that I found relating to this error were solved by doing an svnadmin upgrade, though I have actually tried that and still no joy. Thanks in advance, James.

• Outlook refuses to connect to Exchange

  - by wfaulk

  Outlook 2007 under Windows XP connecting to Exchange 2003 SP2: when started, it flips back and forth between "Connecting to Exchange Server" and "Disconnected" three or four times, then gives up and stays disconnected. I tried deleting the ost file (which was nearly 2GB), turning Cached mode on and off, recreating the account inside the Mail control panel, changing the account to use HTTP, and probably some other things. None of it seemed to make any difference, until … After fiddling with it for a while, I got this absurd error message dialog at startup, and it exits after I click OK: Cannot start Microsoft Office Outlook. Cannot open the Outlook window. The set of folders cannot be opened. Microsoft Exchange is not available. Either there are network problems or the Exchange server is down for maintenance. (I'm not sure if I can even trust that message. It's so long, it just feels like a random offset into Outlook's stack of error messages.) Either way, the Exchange server is available to everyone else, and is available via OWA from that computer. I ran Process Explorer against Outlook and it showed 5 or so ESTABLISHED connections to our Exchange server, plus listening on two UDP ports, and two CLOSE_WAIT connections to localhost. If I managed to look at Outlook's IP connections while it was doing its Connecting/Disconnected dance, it had a huge number of connections open to the Exchange server. It more than filled ProcExp's dialog box; I'm guessing at least 20, probably more. The only other odd thing is that our network admin at some point added a wildcard DNS record to the domain name that we use for email, and now Outlook will sometimes (always?) start by complaining about autodiscover.example.com's SSL certificate. There is a web server there, but it doesn't have any sort of email autodiscover anything on it. It doesn't make any difference if I click "OK" or "Cancel" (or whatever the buttons are). I also added a bogus entry for the hostname to Windows' hosts file, pointing it at 127.0.0.2, and it stopped complaining about the certificate. (The CLOSE_WAIT sockets above were from before I made this change, and went away after.) I don't think this is related, as the same problem should exist for everyone, but it might be. This is the second time this user has had this problem. The first time, I never found a solution other than reinstalling Outlook. Now that it's a pattern, I'd like to find a permanent solution, rather than assume it's a random glitch.

• Windows cannot find the host name "download.microsoft.com" using DNS

  - by joedotnot

  When trying to download a file found on the Microsoft downloads center that starts with, for example, http://download.microsoft.com/download/6/8/7/(some_GUID)/(some_file_name.ext) i get a timeout with "Internet Explorer cannot display the webpage". More information says: Internet connectivity has been lost. The website is temporarily unavailable. The Domain Name Server (DNS) is not reachable. The Domain Name Server (DNS) does not have a listing for the website's domain. If this is an HTTPS (secure) address, click Tools, click Internet Options, click Advanced, and check to be sure the SSL and TLS protocols are enabled under the security section. Diagnose Connection problems says: Windows cannot find the host name "download.microsoft.com" using DNS Bear with me while i expand on the problem: It all started when i tried to download Windows XP mode for my Windows 7 machine. I went to the virtual PC site, then thru the motions of Windows Genuine Advantage which validated ok, but when it redirects to grab the file just times out with above error. (NB: i also tried with the latest Chrome and Firefox but no use due to the Genuine Advantage stuff, so i decided to stick with IE). I am behind an ADSL2+ modem router connecting via wireless (Win 7 Pro laptop); so i hop over to the desktop connected via ethernet (Vista Business), and same result; begin to think site download.microsoft.com site is down. So i give it a break an read up on EDNS, flushing the cache, hosts file, etc... Try again an hour later on the Win 7 machine, still no go; so i turn off the Win 7 (software) firewall, and lo and behold, i can connect and grab any files from download.microsoft.com; (...nice, so we have a Micro$0ft firewall preventing access to a Micro$0ft website, no wonder my auto-updates kept failing but that's another story). But i still am not happy that the desktop connected via ethernet still cannot get to download.microsoft.com, even though i turned off all firewalls, defenders, anti-virus, etc. What is so special / specific about the url download.microsoft.com, any other site is ok, including www.microsoft.com. Any networking guru know what's REALLY going on, and how can i get the desktop to connect? Ping download.microsoft.com - Ping request could not find host download.microsoft.com. Please check the name and try again. Ping google.com or even www.microsoft.com works gives me an IP address. NB: On the wireless laptop ping download.microsoft.com works, i get xxxx.ms.akamai.net [202.7.177.33].

• Custom built machine has much higher power consumption than expected

  - by foraidt

  I built a machine according to the specs of a computer magazine (c't, Germany). According to the magazine, the power consumption should be at around 10W. I don't want to go into the specifics of the hardware but rather ask for general advice on where to look: I updated the BIOS/UEFI version to the latest version, installed all the recommended drivers and unplugged all hardware that's not necessary to boot into Windows. All that was left is the power supply, mainboard, cpu, cpu cooler and one SSD drive. But still I measured a power consumption of 50W, which is 40W more than it should be. I tried booting Linux Mint from a USB stick, so I don't think it's some Windows-related problem.. Where else could I look? Update 1 I dind't want the question to get closed for being too localized but if more details are necessary, here they are: The system is a desktop PC. The power consumption is measured using a Brennenstuhl PM 231 device, which was tested also by c't and they found it quite accurate. The PSU is an Enermax ETL300AWT, the mainboard Intel DH87RL (Socket 1150) and the CPU Intel G3220 (Haswell). Update 2 There is no online version of the article*. The most details I found can be read on its project page (in German, though...) (*)You can pay for downloadable PDFs, however. English translation of that project page Update 3 Regarding the sceptics: It may sound ridiculous but apparently 10W idle consumption is possible with Intel's Haswell architecture. As a kind of proof, there's an additional Blog article explicitly listing the steps needed to reduce the idle consumption to 10W. Additional hardware: I measured the consumption without the HDD, and as expected the usage dropped by around 10W. I have no chassis fans and the CPU fan is a "Scythe Mugen 4" model. It runs at around 600rpm so I think it won't draw much. When stripping off all my extra components I should be at 10W. But I'm not getting anywhere near that. I would be happy to see "just" 15W in the stripped down version but currently I'm not getting below 50W no matter which component I remove. As I see it this cannot be explained by the PSU being less efficient at lower consumption. I also waited half an hour or so (also checked that no Windows updates were running in the background) and the consumption dind't drop by more than a few watts.

• 502 Bad Gateway with nginx + apache + subversion + ssl (SVN COPY)

  - by theplatz

  I've asked this on stackoverflow, but it may be better suited for serverfault... I'm having a problem running Apache + Subversion with SSL behind an Nginx proxy and I'm hoping someone might have the answer. I've scoured google for hours looking for the answer to my problem and can't seem to figure it out. What I'm seeing are "502 (Bad Gateway)" errors when trying to MOVE or COPY using subversion; however, checkouts and commits work fine. Here are the relevant parts (I think) of the nginx and apache config files in question: Nginx upstream subversion_hosts { server 127.0.0.1:80; } server { listen x.x.x.x:80; server_name hostname; access_log /srv/log/nginx/http.access_log main; error_log /srv/log/nginx/http.error_log info; # redirect all requests to https rewrite ^/(.*)$ https://hostname/$1 redirect; } # HTTPS server server { listen x.x.x.x:443; server_name hostname; passenger_enabled on; root /path/to/rails/root; access_log /srv/log/nginx/ssl.access_log main; error_log /srv/log/nginx/ssl.error_log info; ssl on; ssl_certificate server.crt; ssl_certificate_key server.key; add_header Front-End-Https on; location /svn { proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; set $fixed_destination $http_destination; if ( $http_destination ~* ^https(.*)$ ) { set $fixed_destination http$1; } proxy_set_header Destination $fixed_destination; proxy_pass http://subversion_hosts; } } Apache Listen 127.0.0.1:80 <VirtualHost *:80> # in order to support COPY and MOVE, etc - over https (443), # ServerName _must_ be the same as the nginx servername # http://trac.edgewall.org/wiki/TracNginxRecipe ServerName hostname UseCanonicalName on <Location /svn> DAV svn SVNParentPath "/srv/svn" Order deny,allow Deny from all Satisfy any # Some config omitted ... </Location> ErrorLog /var/log/apache2/subversion_error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg. LogLevel warn CustomLog /var/log/apache2/subversion_access.log combined </VirtualHost> From what I could tell while researching this problem, the server name has to match on both the apache server as well as the nginx server, which I've done. Additionally, this problem seems to stick around even if I change the configuration to use http only.

• Changing Physical Path gives blank homepage

  - by Julie

  I have two websites ASP Classic - www.company.com and www.companytesting.com. At this time of year, company.com is pointed to a folder called website2012 and companytesting.com is pointing to a folder called website2013. The contents of those two folders are almost identical, just minor changes for our season change (which I was supposed to do today - lol). Up until a couple of weeks ago, I was running Windows Server 2003. To update the "live" website, I'd make a copy of the test site folder, and rename it website2013R1, and point the test site there, then point the live site at website2012. We now have Windows Server 2008 R2 64. (I had someone migrate the websites to the new server for me.) The companytesting.com site, when I pointed it to website2013R1, worked fine. The company.com site, when I pointed it to website2013 (which worked just before, for the companytesting.com site) gives an empty page. (i.e. view source = nothing there.) There is nothing in the failed request log when this happens. I can use the Explore button/link (upper right) in IIS7.5 and see all of the files there. If I use the browse button (either in general or on the index.asp page) I get the blank page again. One weirdness about how these are set up is that companytesting.com uses a login (which I think is windows authentication - it's simply a single username and password for staff, and to keep the GoogleBots out of it). Obviously, company.com does not. But redirecting the to website2013r1 kept the login in place. (So I'm not absolutely clear whether that's attached to the folder or to the site. Hitting the company.com site after changing the path did not yield a password request.) The permissions on the folders all seem to be the same, but obviously, I'm missing something. Why isn't changing the physical path working? As is probably obvious, I'm not knowledgeable about servers. I did OK in 2003, but since it's not my main task and I'm buried right now, I have barely looked at 2008. So I may have really stupid questions when you ask me to check something.

• Microsoft Office 2003 document (Excel and Word) intermitently, takes 30 seconds to load

  - by Julio Nobre

  I am trying to figure out why a simple .XLS EXCEL workbook is taking, randomly, 30 seconds to open. Before answering: Please, bear mind the following: Problem symptoms Hanging is intermitent and it takes exactly 30 seconds; During hanging there is no cpu or disk activity; It only happens during document load. Every runs smooth after that; Windows Explorer.exe hangs on folder, but all other folders, system and applications are still responsive; There are no consecutive hangings. I have to wait for while to reproduce this behaviour; All samples documents are located on a local drive (C:\BPI); The no document has has macros and have any addins usage; The problem does occurs on others files extensions like .PDF, for example; Office 2003 is being used for several years; The computer is running Windows XP; Computer has several network mapped drives, all addressed to main file server; Recently, main fileserver was replaced by Windows 2011 SBS Standard Edition What I have done so far I have traced machine Explorer.exe, using Process Monitor, added Duration column, and filtered by Duration 1. That's is how I found that hanging was taking exactly 30 seconds. For further information, please refer to Oliver Salzburg tutorial. Using Process Monitor, I have also figured out than five operations were taking most of sample collecting duration. Looking at sample image below, column Operation below you will notice that one single operation was taking 29 seconds; I have tried different documents (.xls and .doc), all of them smaller than 30 KB; I have, temporarily, removed all shortcuts on User Document's folder that were pointing to network drives or shares; I have runned CCleaner to fix registry issues; I made sure that there were no external links on tested workbook or word documents; I have reproduced this behaviour for hours; I have extensivelly researched for hours on the web; Process Monitor's collected and filtered data

• Looking for a NTP Server Software for Windows

  - by Simon

  I'm looking for a, preferably free, NTP Server for Windows Server 2003/2008. We have already tried the built in Windows Time Server, but our tests did show that it is not very accurate, we see time differences up to 500ms. The max time difference we can allow for our application is ~100ms. Now we have already used the Meinberg NTPd for Windows. It works great except we have one big issue with it: If there is a network connection problem between the client and server, the ntp server is in a panic state It won't give the client a new time until we restart the ntp service. This is a big issue which has caused us some trouble. It was working fine for months until there was a network problem we didn't notice, we only noticed it after a week when the time difference was already 30 sec. on the clients. So please suggest some alternative NTP Server for windows. I did Google but I get a lot of unrelated search results. Edit: So far the ntpd windows version was very accurate and I'd like to stick with it. The only problem is the "panic state" after a network disconnect. Maybe some knows here what the cause of this is and how to fix it. Also, I forgot to mention that we have a server/client setup like this: Server1 -- Server2 -- Server3 -- Client1 -- Client2 -- Client3 So Server2 gets its time from Server1, Server3 gets its time from Server2, and the Clients get their time from Server3. Also, there are clients connected directly to Server2. It is important that all Servers and Clients have the exact same time (within ~100ms) Now there was a network problem with Server3 and its clients. The servers run the ntpd port for Windows, which acts as NTP server and client. The clients have Dimension4 as NTP client. After the network problem, the error message in D4 was something like this (out the top of my head, don't have the exact error message): Server response: The server is in a panic state (could not sync clock) I read through the ntpd docs, and the only mention of "panic" is when the time difference is 10000 seconds which will cause to exit the ntpd server but this was not the case. Also there is a "-g" command line switch to disable the panic exit, but it is already set by default. Any ideas what could cause the panic state and how to get rid of it next time?

• Hard freeze on new computer

  - by mphair

  OCZ Gold 3x2GB 240-Pin DDR3 SDRAM PC312800 Palit NE5T240SFHD01 GeForce GT240 1GB 128-bit GDDR5 ASUS P7P55D-E LGA 1156 P55 SATA 6Gb/s USB 3.0 ATX Intel Motherboard Intel Core i7-860 Lynnfield 2.8GHz 8MB L3 Cache LGA 1156 95W Quad-Core Processor SAMSUNG 22X Optical drive (DVD+-R/RW) CORSAIR CMPSU-620HX 620W ATX12V V2.2 Windows 7 Ultimate x64 Brand new system (got it from newegg two days ago) and it booted up and installed windows and ran for a day just fine. Yesterday, I boot it up in the afternoon and run various games at full graphics for most of the day. I turn on WoW and play for a few hours and it hard stalls. No numlock switching, no mouse feedback but nothing going wrong on the screen. No BSOD. I wait a bit to see if the stall is just a temporary one, but then force shutdown the computer. Upon reboot, everything seems fine, windows sees that it didn't shut down properly but I go into normal boot and restart WoW. I'm able to load it up and start running around when it freezes again. This time when I restart, it doesn't even get to BIOS. It starts (power goes on) and it just hangs with no output to the monitors. I shut it off and went to bed. This morning, I turned it on and went into BIOS setup. I'm not terribly experienced with messing with BIOS settings but I checked over them the best I could. Everything seems fine so I boot into windows and browse the internet for a bit looking for a solution, hard freeze within 10 minutes. I restart and go into BIOS and check the CPU temperature, 40c. I'm kinda stumped here. Some people say it might be a memory issue, but why would it take so long for it to come up? Could it have been slowly accessing one memory stick at a time and then it just got to a bad one and that's what is causing it to fail? It seems odd that I don't get a BSOD from a hardware failure. Having the screen just halt with no input or output change seems like a software thing to me. Any thoughts?

• How Do I Restrict Repository Access via WebSVN?

  - by kaybenleroll

  I have multiple subversion repositories which are served up through Apache 2.2 and WebDAV. They are all located in a central place, and I used this debian-administration.org article as the basis (I dropped the use of the database authentication for a simple htpasswd file though). Since then, I have also started using WebSVN. My issue is that not all users on the system should be able to access the different repositories, and the default setup of WebSVN is to allow anyone who can authenticate. According to the WebSVN documentation, the best way around this is to use subversion's path access system, so I looked to create this, using the AuthzSVNAccessFile directive. When I do this though, I keep getting "403 Forbidden" messages. My files look like the following: I have default policy settings in a file: <Location /svn/> DAV svn SVNParentPath /var/lib/svn/repository Order deny,allow Deny from all </Location> Each repository gets a policy file like below: <Location /svn/sysadmin/> Include /var/lib/svn/conf/default_auth.conf AuthName "Repository for sysadmin" require user joebloggs jimsmith mickmurphy </Location> The default_auth.conf file contains this: SVNParentPath /var/lib/svn/repository AuthType basic AuthUserFile /var/lib/svn/conf/.dav_svn.passwd AuthzSVNAccessFile /var/lib/svn/conf/svnaccess.conf I am not fully sure why I need the second SVNParentPath in default_auth.conf, but I just added that today as I was getting error messages as a result of adding the AuthzSVNAccessFile directive. With a totally permissive access file [/] joebloggs = rw the system worked fine (and was essentially unchanged), but as I soon as I start trying to add any kind of restrictions such as [sysadmin:/] joebloggs = rw instead, I get the 'Permission denied' errors again. The log file entries are: [Thu May 28 10:40:17 2009] [error] [client 89.100.219.180] Access denied: 'joebloggs' GET websvn:/ [Thu May 28 10:40:20 2009] [error] [client 89.100.219.180] Access denied: 'joebloggs' GET svn:/sysadmin What do I need to do to get this to work? Have configured apache wrong, or is my understanding of the svnaccess.conf file incorrect? If I am going about this the wrong way, I have no particular attachment to my overall approach, so feel free to offer alternatives as well. UPDATE (20090528-1600): I attempted to implement this answer, but I still cannot get it to work properly. I know most of the configuration is correct, as I have added [/] joebloggs = rw at the start and 'joebloggs' then has all the correct access. When I try to go repository-specific though, doing something like [/] joebloggs = rw [sysadmin:/] mickmurphy = rw then I got a permission denied error for mickmurphy (joebloggs still works), with an error similar to what I already had previously [Thu May 28 10:40:20 2009] [error] [client 89.100.219.180] Access denied: 'mickmurphy' GET svn:/sysadmin Also, I forgot to explain previously that all my repositories are underneath /var/lib/svn/repository UPDATE (20090529-1245): Still no luck getting this to work, but all the signs seem to be pointing to the issue being with path-access control in subversion not working properly. My assumption is that I have not conf

• Can Vagrant point to a directory of Puppet manifests for execution?

  - by SeligkeitIstInGott

  I am using Vagrant to jump start some initial Puppet config and am confused on how to include/run multiple manifests (other than just site.pp) in the puppet execution workflow without making the extra manifests into modules and including them that way. In the puppet manifests directory that I point Vagrant to (see below) I have two manifests that I want executed: site.pp and hierasetup.pp. config.vm.provision "puppet" do |puppet| puppet.manifests_path = "puppet_files/manifests" puppet.module_path = "puppet_files/modules" puppet.manifest_file = "site.pp" puppet.options = "--verbose --debug" end Currently I am having site.pp be the manifest that calls hierasetup.pp. My site.pp looks like this: File { owner => 'root', group => 'root', mode => '0644', } import "hierasetup.pp" include jboss But I get this error about the deprecation of "import": Warning: The use of 'import' is deprecated at /tmp/vagrant-puppet-1/manifests/site.pp:33. See http://links.puppetlabs.com/puppet-import-deprecation (at grammar.ra:610:in `_reduce_190') According to the referenced URL under "Things to try instead" it says "To keep your node definitions in separate files, specify a directory as your main manifest". Further this puppet doc on main manifests says: "Recommended: If you’re using the main manifest heavily instead of relying on an ENC, consider changing the manifest setting to $confdir/manifests. This lets you split up your top-level code into multiple files while avoiding the import keyword. It will also match the behavior of simple environments." It appears that Puppet can reference an entire directory instead of just a specific manifest file, such that I would expect that Vagrant would make a provision for this and allow me to drop the "puppet.manifest_file = "site.pp" line and point to the parent directory instead in which all the *.pp files there will be executed. However removing that line in Vagrant merely generates a complaint about an expected "default.pp" in its stead: puppet provisioner: * The configured Puppet manifest is missing. Please specify a path to an existing manifest: /some/path/puppet_files/manifests/default.pp So: Firstly, do I understand the "new" (non-import) way of calling multiple manifests correctly, in that a directory is to be pointed to in which all the *.pp files inside it will be executed? And secondly, has Vagrant "caught up" with this new change to accommodate the referencing of directories in conjunction with Puppet's deprecation of "import"? Update: Thanks to Shane the issue with #2 (Vagrant's code not being caught up to allow pointing to puppet manifest directories) was reported on Vagrant's GitHub issue tracker site and has since been patched: https://github.com/mitchellh/vagrant/issues/4169

• Unextending Sharepoint 2007 Web Application from a zone

  - by dunxd

  When our Sharepoint was migrated from Sharepoint 2003 to Sharepoint 2007 (both fully paid versions), the consultants who carried it out extended each web app into two IIS sites/zones (e.g. the original Web App was http://intranet, then http://newintranet and http://intranet would be created for Sharepoint 2007 - each with its own IIS site). The idea was that during the migration period we would set up DNS to point the old url to SP2003 servers and the new one to SP2007, then once the migration was complete, do a DNS change so the SP2007 would recieve the requests to the http://intranet type URLs. Unfortunately the contractors did not tidy up the application extensions and IIS sites after the migration, and for some time both URLs were in use, resulting in many document links pointing to the http://newintranet type URLs. This means I need to maintain these URLs. Due to a rejig of organisation structure we now need to relocate some Sharepoint sites, and I'd like to use the RDA Collaboration Sharepoint URL Redirector feature. However a limitation of this is that it doesn't work for Web Applications which have been extended into multiple zones. So I have a need to tidy up the situation that our consultants left behind. I think the right thing to do is use the "Remove Sharepoint from IIS Web Site" page in Central Admin to remove the zone for the newintranet type sites, and select the option to also delete the IIS site. That should result in having no IIS sites listening for http://newintranet type URLs. Is this the right procedure? Once I have done that I need to set up Sharepoint to receive requests sent to the http://newintranet type URLs so they will continue to work. I am not sure if I should do this: using Alternative Access Mappings or, by adding a host header to the IIS site or, creating a non Sharepoint IIS site for each http://newintranet type URL, and use IIS redirection to forward the requests to the new URL using variables to pass the path to the Sharepoint site. Does anyone have any thoughts on these options, or any other way of achieving this? Sharepoint 2007 is running on Windows 2003 with IIS6. We don't currently have plans/budget to upgrade to Sharepoint 2010.

• Operative systems on SD cards

  - by HisDudeness

  I was getting some wild ideas the last days, like putting some operative systems into SD cards rather than on my hard drive. I'll go further into details now and explain what lead me to consider this probably abominable decision. I am on a laptop (that means I have a native SD-card reader) which is currently running a cross-distro setup, with a bunch of Linux systems (placed in dedicated ext4 logical partitions into a huge extended one) regulated by an unique GRUB. Since today, my laptop haven't even seen any Windows system with binoculars. I was thinking about placing all the os part of my setup into a Secure Digital to save all my 500 Gb Hard Drive for documents, music, videos and so on, and being able to just remove the SD and boot my system into another computer too, as well as having the possibility of booting other systems into mine by just plugging in another SD, without having to keep it constantly placed in my PC. Also, in the remote case in the near future I just wanted to boot Windows 8 in it, I read it causes major boot incompatibility issues with other systems by needing a digital signature in order for them to start. By having it in a removable drive, I could just get rid of it when I'm needing him and switch its card with Linux one, and so not having any obstacles to their boot. Now, my questions are: I know unlikely traditional rotating disk drives, integrated circuits ones have a limited lifespan in terms of cluster rewriting. Is it an obstacle to that kind of usage? I mean, some Ultrabooks are using SSD now, is it the same issue, or there are some differences between Solid State Drives and Secure Digitals in that sense? Maybe having them to store system files which are in fixed positions (making the even-usage of cluster technology useless) constantly being re-read and updated and similar things just gets them soon unserviceable, do it? Second question: are all motherboards and BIOSes able to boot from SDs just like they are from USB pen drives (I mean, provided card reader is USB-connected, isn't it)? Or can't bootloaders like GRUB be installed on SDs working? If they can't, is it a solution installing GRUB to MBR and making boot option pointing to SD? Will it work? Are there any other problems to installing OSs on a Secure Digital?

• Error: Multilib version problems found

  - by Kovács Ákos

  What causes this error? Error: Multilib version problems found. This often means that the root cause is something else and multilib version checking is just pointing out that there is a problem. Eg.: 1. You have an upgrade for glibc which is missing some dependency that another package requires. Yum is trying to solve this by installing an older version of glibc of the different architecture. If you exclude the bad architecture yum will tell you what the root cause is (which package requires what). You can try redoing the upgrade with --exclude glibc.otherarch ... this should give you an error message showing the root cause of the problem. 2. You have multiple architectures of glibc installed, but yum can only see an upgrade for one of those arcitectures. If you don't want/need both architectures anymore then you can remove the one with the missing update and everything will work. 3. You have duplicate versions of glibc installed already. You can use "yum check" to get yum show these errors. ...you can also use --setopt=protected_multilib=false to remove this checking, however this is almost never the correct thing to do as something else is very likely to go wrong (often causing much more problems).

• Ping Unknown Host on CentOS at EC2

  - by organicveggie

  Weird problem. We have a collection of servers running CentOS 5 on EC2. The setup includes two DNS servers and two LDAP servers. DNS has a CNAME pointing at the primary LDAP server. One machine (and only one machine) is giving me problems. I can ssh into the server using LDAP authentication. But once I'm on the machine, ping won't resolve the LDAP host even though DNS seems to work fine. Here's ping: $ ping ldap.mycompany.ec2 ping: unknown host ldap.mycompany.ec2 Here's the output of dig: $ dig ldap.mycompany.ec2 ; <<>> DiG 9.3.6-P1-RedHat-9.3.6-4.P1.el5_5.3 <<>> ldap.studyblue.ec2 ;; global options: printcmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 2893 ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 2, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;ldap.mycompany.ec2.

• How can I reverse mouse movement (X & Y axis) system-wide? (Win 7 x64)

  - by Scivitri

  Short Version I'm looking for a way to reverse the X and Y mouse axis movements. The computer is running Windows 7, x64 and Logitech SetPoint 6.32. I would like a system-level, permanent fix; such as a mouse driver modification or a registry tweak. Does anyone know of a solid way of implementing this, or how to find the registry values to change this? I'll settle quite happily for how to enable the orientation feature in SetPoint 6.32 for mice as well as trackballs. Long Version People seem never to understand why I would want this, and I commonly hear "just use the mouse right-side up!" advice. Dyslexia is not something which can be cured by "just reading things right." While I appreciate the attempts to help, I'm hoping some background may help people understand. I have a user with an unusual form of dyslexia, for whom mouse movements are backward. If she wants to move her cursor left, she will move the mouse right. If she wants the cursor to move up, she'll move the mouse down. She used to hold her mouse upside-down, which makes sophisticated clicking difficult, is terrible for ergonomics, and makes multi-button mice completely useless. In olden times, mouse drivers included an orientation feature (typically a hot-air balloon you dragged upward to set the mouse movement orientation) which could be used to set the relationship between mouse movement and cursor movement. Several years ago, mouse drivers were "improved" and this feature has since been limited to trackballs. After losing the orientation feature she went back to upside-down mousing for a bit, until finding UberOptions, a tweak for Logitech SetPoint, which would enable all features for all pointing devices. This included the orientation feature. And there was much rejoicing. Now her mouse has died, and current Logitech mice require a newer version of SetPoint for which UberOptions has not been updated. We've also seen MAF-Mouse (the developer indicated the version for 64-bit Windows does not support USB mice, yet) and Sakasa (while it works, commentary on the web indicate it tends to break randomly and often. It's also just a running program, so not system-wide.). I have seen some very sophisticated registry hacks. For example, I used to use a hack which would change the codes created by the F1-F12 keys when the F-Lock key was invented and defaulted to screwing my keyboard up. I'm hoping there's a way to flip X and Y in the registry; or some other, similar, system-level tweak out there. Another solution could be re-enabling the orientation feature for mice, as well as trackballs. It's very frustrating that input device drivers include the functionality we desperately need for an accessibilty concern, but it's been disabled in the name of making the drivers more idiot-proof.

• I want to virtualize my workstation (Tier 1), Looking for Bare Metal Hypervisor for consumer grade components

  - by Chase Florell

  I find myself in this similar bind at least once a year. The bind whereby I'm either upgrading a motherboard, or an OS hard drive. It drives me crazy to have to reinstall Windows, Visual Studio, all my addins, reconfigure my settings etc... every single time. I have a layout and I like and I want to stick with it. My question is... Is there a Bare Metal Hypervisor on the market that will enable me to virtualize my consumer grade workstation? I really want to avoid Host/Client virtualization. Bare Metal is definitely a better way to go for my needs. Is this a good approach, or am I going to suffer some other undesirable side effects by doing this? Clarification My machine has very limited purposes. My primary use is Visual Studio 2010 Professional where I develop ASP.NET MVC Web Applications. The second piece of software that I use (that's system intensive) is Photoshop CS3. Beyond that, my applications are limited to Outlook, Internet Explorer, Firefox, Opera, Chrome, LinqPad, and various other (small) apps. Beyond this, I'm considering working on a node.js project and might run ubuntu on the same hypervisor if possible. System Specs: Gigabyte Motherboard Intel i7 920 12 GB Ram basic 500GB 7200RPM HDD for OS 4 VelociRaptors in Raid 1/0 for build disk Dual GTS250 (512MB) Graphics cards (non SLI) for quad monitors On a side note I also wouldn't be opposed to an alternative suggestion if the limitations are too great. I could install the ESXi (or Zen Server) on my box, and build a separate "thin client" to RDP into the virtual machine. It appears as though RDP supports dual monitors. Edit (Dec 9, 2011) It's been nearly a year since I first asked this question. Since then, there have been a lot of great strides in Hypervisor technology... AND MokaFive is now released for corporate use. I'd love to dig into this question a little more and find out if there is a solid BareMetal Hypervisor for workstations running consumer grade components (IE: not Dell, HP, Lenovo, Etc).

• Graphics card artifacting

  - by White Phoenix

  This is my current build: EVGA X58 (first generation) motherboard Intel i7 965 @ stock clocks 3x 2GB DDR3-1600 Corsair RAM at stock timings and voltages Corsair AX750 80 Plus Gold PSU 1 Optical Drive 1 Seagate 7200.10 500 GB drive 2x Western Digital Caviar Black 1 TB drives OCZ Vertex 1 60 GB EVGA GTX 460 Antec 1200 case HT-Omega Striker 7.1 Sound Card Windows 7 32-bit Professional (PAE Enabled) My graphics card started artifacting while I was playing a game. It artifacted, the display blinked, then I got an NVIDIA driver has crashed and recovered message. Kept going, more artifacts, another crash, but this time my display blanked out and I couldn't do anything. Restarted my computer - artifacting is in the BIOS - got to Windows 7 but it BSOD'd before I could even log in. I restarted the computer again - artifacts cleared themselves out and I managed to get to Win7, but it soon started blinking in and out and artifacting again. Checked the card temps and they're well within range. (50 idle, 70 full load) The ambient temperature here is about 80-85F with high humidity. Tried Safe Mode and it still froze up/BSOD'd. Already tried the following to fix this problem: - Reseat the graphics card and swapped in a different slot. - Removed cover on card and sprayed with compressed air to clean it out. - Swapped around memory and/or went with only using one stick at a time. - Underclocked card I called EVGA Tech Support and they said that the voltage on the 12V rail of my Corsair AX750 PSU was on the high end of the "acceptable" range (12.4V, highest within acceptable range is 12.6V - optimal is obviously 12V). They gave me an RMA number anyway, but I want to get a second opinion from you all before I send this thing off, as shipping from where I live to EVGA is kind of pricey. This PSU is only 6 months old. So that I don't have to play RMA tag, which case would be most likely? I'm strapped for cash at the moment so I want to reduce the amount of RMAs I have to do since shipping is expensive here. Is there any surefire way to test to see if it's really the graphics card or the PSU? I tried unplugging any devices that were connected to the 12V rail (except for my SSD and graphics card) as I do have 3 mechanical hard drives, but the voltage for that rail didn't drop (it remained at 12.4V). I'm fairly sure it isn't the drivers since I'm getting the artifacting at the BIOS too. Right now I'm back in Windows 7 but I don't know for how long until it messes up again. Any ideas?

• Virtual Private Hosting DNS configuration

  - by Ciel

  I did a great deal of reading here before posting this because I didn't want to post a duplicate - but I'm on a bit of a deadline and getting frustrated, so here goes... I very, very, very sincerely apologize if this is long winded or hard to read. Please - please just ask for any information or clarification and I will give it as quickly as I possibly can. This has become very frustrating to me and this is the last place I know to turn. I have no experience with setting up DNS, no experience with nameservers, and no peers to go to for help. So this is kind of my last ditch effort. The task of setting up a private server has, through circumstances beyond my control, fallen into my lap. I own a domain (hereafter referred to as yyy.com) and have always used shared hosting - I buy a package and just point it to the domain nameservers they give me. It's always been simple. yyy.com is registered with network solutions Now I have purchased a Virtual Private Hosting package from GoDaddy.com - and it comes with Plesk 11. I have no earthly idea how to begin to get the right nameserver for yyy.com. I have gone through the instructions and have wound up exceedingly frustrated. I have 2 IP addresses from GoDaddy for the server. This is what I have so far, and I cannot tell if it is working (Since propogation takes so long, it is extremely hard to test for me) IP 1 : XX.XX.XX.XX IP 2 : YY.YY.YY.YY (obviously hidden for privacy) Now after going through the documentation setup and waiting a few days, this is the setup I have - and so far it does not appear to be working. Host Record type Value XX.XX.XX.XX / 24 PTR yyy.com. yyy.com. NS ns1.yyy.com. yyy.com. A XX.XX.XX.XX yyy.com. MX (10) mail.yyy.com. ftp.yyy.com. CNAME yyy.com. ipv4.yyy.com. A XX.XX.XX.XX mail.yyy.com. A XX.XX.XX.XX mssql.yyy.com. A XX.XX.XX.XX ns1.yyy.com. A XX.XX.XX.XX ns2.yyy.com. A YY.YY.YY.YY webmail.yyy.com. A XX.XX.XX.XX www.yyy.com. CNAME yyy.com. yyy.com is pointing to both ns1.yyy.com and ns2.yyy.com Can anyone give me some assistance here? This is a learning experience for me and days of documentation have left me very confused.
