• Windows XP VM on VMWare ESXi 4.1 "pausing" / blocked occasionally

  - by FelixD

  We have an issue with Windows XP SP3 VMs on VMWare ESXi 4.1.0 (the free version): They sometimes seem to "pause" for several minutes. This happens rarely (maybe once a month per VM, at least noticed only that often), but still is an issue for us. It happens for three different but similar VMs on three pretty different hosts (different hardware). I have the feeling that the "pausing" is not actually the CPU blocking, but probably the harddisks, but not 100% sure. The servers have one IDE disk (C:) and one SCSI (D:) and it might be either of the two. I have seen scheduled tasks simply not starting for up to 9 minutes and then running normally again with normal speed. They were totally blocked. This is not a load issue, the VMWare hosts have average load and the VMs in question already have reserved CPU resources plus high priorities for CPU and disk. The Windows boxes run mainly MySQL, Tomcat, FileZilla server, Cygwin stuff, Java + R applications, VMWare client, Elusiva Terminal Server pro, Nagios client. Not sure if this might be related with any of that software (e.g. Elusiva). Trying to debug this, there was nothing visible in Windows Event log, other logs in C:\Windows, VMWare events etc. Unfortunately the vmware.log file ends with "Log throttled". We found that we ran into 2 VMWare bugs there: The VMWare client writes lots on bogus messages in the vmware.log, which we now disabled (log level error setting) plus the bug that VMWare does not unthrottle the log (at least so far despite VM reboots). I know there is not much guidance and that may also be the reason why I so far didn't find anything related on the web or on ServerFault, but maybe some of this rings a bell with someone? Or please direct me to what more info to post. I hope that the vmware.logs get unthrottled eventually (can't easily restart the hosts at the moment). Thanks for any input!

• htaccess rewriting all subdomains to subdirectories

  - by indorock

  I'm trying to build a catch-all for any subdomains (not captured by previous rewrite rules) for a certain domain, and serve a website from a subdirectory that resides in the same folder as the .htaccess file. I already have my vhosts.conf to send all unmapped requests to a "playground" folder, where I want to easily create new subdomains by simply adding a subfolder. So, my structure looks like this: /var/www/playground |-> /foo |-> /bar The .htacces living inside the /playground folder and /foo and /bar being seperate websites. I want http://foo.domain.com to point to /foo and http://bar.domain.com to /bar. Here is my .htaccess file: RewriteEngine On RewriteCond %{HTTP_HOST} ^([^.]+).domain.com$ [NC] RewriteCond %{REQUEST_URI} !^/%1/(.*) RewriteRule ^(.*) /%1/$1 [L] This is supposed to capture the subdomain, add it as a subfolder in RewriteRule, then append after the slash and path information. The second RewriteCond is there to prevent an infinite loop. My idea was that %1 in the second RewriteCond would be able to capture the capture group in the first RewriteCond. But so far I haven't had any success, it's always ending up in a redirect loop. If I would replace %1 in the second RewriteCond with hardcoded 'foo' or 'bar', it works, which leads me to believe that you cannot refer to a capture group inside a RewriteCond. Is is true? Or am I missing something?

• mysqldump --where with = operator doesn't get all rows = - Help!

  - by JonathanLIVE

  I have a situation with a particular table that now thinks it contains 4 Petabytes of data. I know that sounds cool, but I assure you, it is only on a 60GB partition. This table has 9 fields in it. One of them is a domain_id field. It is the best field to identify the rows by, as there are only approximately 6300 of them. The only other field option to match has over 2million records, and thats just more difficult. I cannot do a straight mysqldump because it will attempt to output all 4PB of data and fill the drive long before it gets close to that, so I need to surgically remove the good stuff, destroy the db, and recreate it. I believe if I can do a dump for each domain_id record, then I will get most of the usable data out of it. This is what I am trying to use: mysqldump -u root --skip-opt -q --no-create-info --skip-add-drop-table --max_allowed_packet=1000000000 database table --where="domain_id=10" domains10.sql Using this I expect every row with the domain_id 10 to be exported. However, when I check the export, I am only getting 1 row, when however I look at the db, there are many many rows. It is as though the operator just finds one, then gives up. I have tried various operators. Using the < or I am able to get more of the data, but the export stops short at certain rows where the data has been compromised. With over 6000 to go through, I can't narrow down which rows are being affected in the export easily enough. So, what I need is an operator that will basically do what I thought = would do, simply give me an export of all records that match the specific field. Also note, the only way I got this DB even accessible is through an innodb force recovery 3. So I need to get this right, because after this is done, I have to drop the db in order to make mysql functional again. Looking forward to any helpful answers.

• Router as primary DNS server, Server as alternate? (or vice versa)

  - by Jakobud

  We have a very small business network, with a typical cable modem hooked into a DD-WRT router. We also run a basic CentOS server that does a variety of things, including acting as the primary DNS server for the office. The reason we need an internal DNS server is because we do a lot of internal web development and use the DNS server to add/remove various local network URLs for internal website testing (like www.testsite.com.local). It's very important for us to be able to add/remove URL aliases easily to the DNS. The problem with this setup is that if we ever need to restart the CentOS server or take it offline for upgrades or whatever, then internet access for all computers on the network is lost. That's because each computer relies on that DNS server to access the Internet I guess? The router is online all the time and very very rarely has to be restarted. It would be nice if we could setup my router to be the primary DNS server but still be running DNS on my server. So we could still add my local testing website URLs to the DNS server in CentOS, but be able to also take down the CentOS server without loosing Internet access on the network. How would this be setup? Would I simply need to add both router + server IP addresses to each computer's IP settings? Is the router primary DNS and server secondary DNS server? Or vice versa? Or can one of the two serve as a fallback for the other? What (if anything) needs to be configured on both the router and server in order for them to recognize that the other DNS server exists on the network? Does anyone have any newb-friendly resources for setting up something like this?

• User unable to delete folder / files "File in use by another user" Server 2003

  - by Az

  I am administering a standalone Windows 2003 Terminal Server with no domain membership. Occasionally (about once a week or so) a user will attempt to delete a sub-folder in a Shared folder and gets denied with "File in use by another user". I tried checking the shared folder snap-in and that folder is not open. She has full control and is the owner of the folder as well. I even checked in "Effective permissions" for some of the folders / files she cant delete and she truly has full control. I am able to delete the folder as Administrator with no problem. Another odd thing, she can delete the files IN the folder most of the time (this issue happens on both folders and files in the share). Sometimes merely waiting a day or two will allow her to delete the folder or files. I am curious as to why she gets the message that it is in use as creator/owner with full control yet I don't get it simply as a member of the Admin group. If anyone out there has any ideas I'd love to hear them! THANK YOU.

• Windows Server 2008 R2 grinds to a screeching halt during file copy operations

  - by skolima

  When my Windows Server 2008 R2 machine is performing any large disk operations (copying 10GB files from one drive to another, copying similar file over network, merging HyperV snapshots, compressing large files), performance of the whole machine slows down terribly, everything becomes unresponsive. This is noticeable in any situation when the disk access is large enough not to fit in the cache. Are there any settings available for tuning this behaviour? I can accept slower file transfer if this would give me more responsiveness. System details: Dell Optiflex 960, Core 2 Quad Q9650, 8GB RAM, 2 SATA drives - 320GB (ST3320418AS) and 1TB (ST31000528AS), NCQ active on both, Intel 82564LM-3 Gigabit Ethernet, ATI HD 3450 graphics, Intel ICH10 bridge. We have multiple machines like this, every one is exhibiting the same behaviour. I though this was overkill for a workstation, apparently I was mistaken. Update: I guess I shouldn't have mentioned the HyperV at all. The above configuration is a standard workstation setup at the company I work for, this is not a server of any kind. I have at most 3 virtual machines working, and usually I'm the only person accessing them. Never the less, the slowdown occurs even when no VMs are running. On a Linux machine I'd simply ionice the copy process and I could forget about it, is there any way to manage IO priorities on Windows?

• extra managed+unmanaged switches @ home/office -- best (mis)usage scenario? what would you do?

  - by locuse

  up front -- definitely NOT a mission-critical kind of question. after a 'spring cleaning' of my local office, i've ended up with two 'spare' GigE switches at my home/office -- one managed, capable of VLANs, QoS, etc, and the other unmanaged. i've got more ports than i need. in fact EACH switch has more total ports than i need. but, since i can't have these just sitting around not doing SOMETHING ... ;-) i'm interested in ideas for best combined use of these switches. my local topology is simple: [ net ] -- [ adsl2 modem ] -- [linux firewall/router/DNS ] _______________| | [ some arrangement of the 2 GigE switches ] | ( ... stuff on the lan ... ) [WAP1] [voip ATA] [printer] [desktop1] [mail server] [Xen server [desktop2] ( mostly dev, [desktop3] + file server [desktop4] + media server)] the MailServer is a production mail server the XenServer serves some low vol to the 'net; the MediaServer guest serves ONLY to the LAN is there, e.g., any performance value in segmenting off any of the LAN using the managed switch (VLAN? QoS tagging? something?), feeding the rest into the connected unmanaged switch? or should i simply use one of the switches & be done with it, and use the other for a coffee-cup stand?

• If I ssh to a domain provided by dyndns, does my password go through them?

  - by D Connors

  I'm running Ubuntu on my work PC, and my work place provides me with a static IP address but not with a domain. It's sometimes useful for me to connect to that PC through ssh, but it's not common enough for me to instantly remember the IP number. So I set um a dyndns account, and associated a short and intuitive domain name to that IP. Here's my question, when I try to ssh to the domain, it asks me $ ssh [email protected] The authenticity of host 'something.there.foo (xx.xx.xx.xx)' can't be established. RSA key fingerprint is 'ALPHANUMERIC STRING' Are you sure you want to continue connecting (yes/no)? That surprised me a little bit. I have already registered the RSA fingerprint by connecting directly to the IP address. I thought the domain name was simply a convenient way of pointing me in the right direction (i. e. the ip address), but that message makes me think my data is actually going through their servers or something. Which one is it? Am I sending my password through someone else's server? Or is ssh just really really careful, thus warning me even if the final destination is a know host? The ssh server I'm using is the openssh-server package.

• Automating Access 2007 Queries (changing one criteria)

  - by Graphth

  So, I have 6 queries and I want to run them all once at the end of each month. (I know a bit about SQL but they're simply built using Access's design view). So, in the next few days, perhaps I'll run the 6 queries for May, as May just ended. I only want the data from the month that just ended, so the query has Criteria set as the name of the month (e.g., May). Now, it's not hugely time consuming to change all of these each month, but is there some way to automate this? Currently, they're all set to April and I want to change them all to May when I run them in a few days. And each month, I'd like to type the month (perhaps in a textbox in a form or somewhere else if you know a better way) just once and have it change all 6 queries, without having to manually open all 6, scroll over to the right field and change the Criteria. Note (about VBA): I have used Excel VBA so I know the basics of VBA but I don't really know anything specific to Access (other than seeing code a few times). And, others will use this who do not know anything about Access VBA. So, I think I have found a similar question/answer that could do this in VBA, but I'd rather do it some other way. If the query needs to be slightly redesigned later, probably by someone who doesn't know Access VBA at all, it'd be nice to have a solution not involving VBA if that is even possible.

• Asterisk relay between multiple subnets

  - by immoune

  I wonder what's the best way to go when you have phones on multiple networks which are not directly reachable. I have 3 networks 10.3.x.x 10.6.x.x 10.17.x.x My asterisk server resides on the 10.3.0.5 IP. The machines from the 10.6 and 10.17 networks are routed here through VPN tunnels. At this point we don't talk about NAT anywhere on the network just pure routing. Since the 10.3.0.5 PBX has routes back to all the subnet's it has no problem to communicate with softphones/hardphones from these ranges. The problem comes from that Asterisk (as far as I understand) only responsible for the SIP communication part not the Audio/Video transmission which is in P2P fashion done between the devices. So although a client using sipdroid from 10.6.x.x is able to connect to the pbx (10.3.0.5) and dial a bria client on the 10.17.x.x network once the phone rings out and the call establishes no audio will be transmitted simply because it has no way to directly connect there. For this there are multiple solutions described in this text: http://msdn.microsoft.com/en-us/library/ee480411%28v=winembedded.60%29.aspx What I would prefer is to keep these networks segregated as they are now. What would be the best solution? Is it possible to actually relay through all the audio/video information through the Asterisk server? That would be the best in my case, I using Astlinux there which has a lot of other parts. Thanks

• Windows VPN client connect on different port

  - by John Gardeniers

  Scenario: Two Windows Server 2003 machines running RRAS VPNs. The firewall port forwards 1723 to one of those machines for normal remote access. I'd like to find a way to connect to the second machine as well. Not because I need to but just because it's the sort of thing I reckon should be possible but can't figure out how to do. Is it possible to have the Windows PPTP VPN client (on XP in this instance) connect on a port other than 1723? If so, I can simply port forward another port to the second server. I've done a fair bit of Googling over the last few days and have only found others asking the same question but no answers. I have of course tried to add a port number in the host name or IP connection box, in various formats, but to no avail. While this might be possible with a third part client I'm really only interested in whether or not it can be done with the Windows built-in client and if so how?. Perhaps there's a registry hack I'm not aware of?

• Why can't I connect to my home SSH (SFTP) server? What am I doing wrong?

  - by Rolo

  I am new to this topic of creating a SFTP server on one's computer. I would like to be able to access the folder on my Windows XP computer via SFTP from another computer or a phone. The following is what I have done so far: I have installed SSH Windows and everything is setup correctly because I can access it (the folder on my pc) via WinSCP. I however cannot access it from my phone. It doesn't connect. The phone can be on the same wireless network as the Windows XP computer, but I would prefer to be able to access this when not in the same network. Now, from what I have read and understood, the following is the information needed to connect: 1) Host Name: This would be my computer's ip address which I access by typing ipconfig in a cmd prompt (I access this easily on my computer because I simply put in localhost or 127.0.0.1) 2) Port Number: That would be port 22 (I have also added this to my router in the port forwarding section). 3) Username: This would be my Windows XP username. This however is my full name, including my middle initial followed by a period. I am wondering if this is maybe causing problems in accessing it from my phone, since the name has spaces and punctuation (the period). 4) Password: The password of my Windows XP computer Extra Info: When I say phone, I mean an Android phone and I am using an ftp / sftp app to access my pc via the phone's cellular network (I also tried the wireless, but that didn't work as well). I have tried more than one program. On one program it tells me Connection timed out and on another it tells me "timeout:socket is not established" Also, I know that I can use the site noip, but I prefer to connect this way first. Also, because I am new to this, I would like to look into what exactly noip is doing and if they would be seeing my files as they are transferred from phone to pc. Thanking you in advance for your help.

• Advanced cell selection in Excel

  - by Supuhstar

  I am new to this flavor of StackExchange, so if this belongs elsewhere, please move it; I figured this would be the best place, though. I am making an Excel Worksheet that simply stores basic financial data in 5 columns (Check Number, Date of Transaction, Description, Profit from Transaction, and Balance After Transaction) and indefinite rows. Each worksheet represents one month, and each Workbook represents a year. As I make or receive a payment, I store it as a new row, which, inherently, makes the number of rows per month indefinite. Each transaction's Balance cell is the sum of the Balance cell of the row above it and the Profit cell of its row. I want each month to start off with a special row (first one after column headers) that displays a summary of the last month's transactions. For instance, the Balance After Transaction cell would display the last row's balance, and the Profit from Transaction cell would display the overall profits of the month) I know that if I knew every month had exactly 100 expenses, I could achieve this for March with the following formulas for profit and balance, respectively: =February!E2 - February!E102 =February!E102 However, I do NOT know how many rows will be in each month's table, and I'd like to automate this as much as possible (for instance, if I find a missed or duplicated expense in January, I don't want to have to update all the formulas that point to the ending January balance). How can I have Excel automatically use the last entered value in a column, in any given Excel spreadsheet, in a formula?

• How to "open" existing VMs in Hyper-V without importing them?

  - by Borek

  I had a PC with two physical disks: C: containing the host operating system D: containing a folder D:\VMs where all my virtual machines were stored Now, the C: disk died. I bought a new one, reinstalled Windows on it, enabled Hyper-V feature and now I just need to open the VMs from the D:\VMs folder. However, I don't seem to be able to find a menu item or anything that would allow me to do that - the only thing I see is the "import" command which unfortunately requires the VMs to be explicitly exported (my machines weren't). I firmly believe that when I have all the files constituting a VM (the VHD file, some XML files describing the settings etc.) it must be somehow possible to just "open" these existing VMs in Hyper-V, right? What command am I missing? Edit: I know I can create a blank virtual machines and then just point them to use existing VHDs. However, I am not sure about all the different settings I've made to those VMs so I hope there's a way to simply open those existing VMs instead of recreating them.

• Is there anything like Heroku for PHP and/or .NET?

  - by Wayne M

  In my area PHP is very widespread, so is .NET. Ruby not so much; most places have never heard of it. For some personal things I am "forced" to choose Rails because I want to take advantage of Heroku - the ability to deploy and scale on the cloud very easily is the main reason. Also, they offer a small FREE plan, with no ads or strings attached, that I can use for demo sites or, in this case, for my business' static page; as a totally bootstrapped startup I have maybe $50 or so in initial capital and cannot afford to pay monthly fees while I'm getting started. Are there any similar offerings for other languages? Specifically, I really like the small, 5MB site for free that Heroku offers - is there anything like that for PHP and/or .NET? I'm not even that concerned about the "cloud" part, but that would be a nice bonus. If there is, I might be able to kill two birds with one stone and pick up a useful skill as I'm doing my own thing instead of using something that nobody else knows or cares about. I should add I'm specifically interested in something that offers a free plan. As I said, Heroku has a 5mb plan that you can have as many as you want for free; I have yet to find anything similar for any other platform (most of the "free" sites require you to have ugly banners on your page, or don't allow you to use your own domain name), and to be honest I'm not too thrilled about using Ruby on Rails for everything simply to take advantage of this. I'm asking this here because I already asked it on StackOverflow and someone suggested it would be better suited here.

• Logging won't stop on log file after renaming/moving it.... how do I stop it?

  - by Jakobud

  Just discovered that logrotate is not rotating our firewall log. So it's up to 12G in size. I need to split up the file into smaller chunks and start manually rotating them so I can get things back on track. However before I start splitting the firewall up, I need to stop the firewall from logging to the current firewall log file and force it to start logging to a new empty file. This way I'm not trying to split up or rotate a log file that is still constantly growing. I tried to simply do this: mv firewall firewall.old touch firewall I expected to see the new empty firewall file to start growing in size, but no... the firewall.old is still be logged to. Then I tried to start/stop iptables. No change. firewall.old is still the log file. I tried to move it to another directory. That didn't help. I tried to stop iptables, then change the filename and create a new firewall file and then start iptables again, but no change. How do I stop the logging on this file and force it to start logging on a new file?

• ZFS & Deduplicating FLAC Data

  - by jasongullickson

  I'm experimenting with using ZFS to deduplicate a large library of FLAC files. The purpose of this is twofold: Reduce storage utilization Reduce bandwidth needed to sync the library with cloud storage Many of these files are of the same music tracks but from different physical media. This means that for the most part they are the same and usually close to the same size, which makes me think that they should benefit from block-level deduplication. However in my testing I'm not seeing good results. When I create a pool and add three of these tracks (identical songs from different source media) zpool list reports 1.00 dedupe. If I copy all of the files (make exact duplicates of the three) dedupe climbs, so I know that it is enabled and functioning, but it's not finding any duplication in the original collection of files. My first thought was that perhaps some of the variable header data (metadata tags, etc.) might be mis-aligning the bulk of the data in these files (the audio frames) but even making the header data consistent across the three files doesn't seem to have any impact on deduplication. I'm considering taking alternate routes (testing other dedupe filesystems as well as some custom code) but since we're already using ZFS and I like the ZFS replication options, I'd prefer to use ZFS dedupe for this project; but perhaps it's simply not capable of working well with this sort of data. Any feedback regarding tuning that might improve dedupe performance for this sort of dataset, or confirmation that ZFS dedupe is not the right tool for this job are appreciated.

• 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.

• Swapping RAID sets in and out of the same controller

  - by hazymat

  This is a really simple question, and the answer is probably encoded in various wikipedia articles, however my question is reasonably specific, and I need a bulletproof answer! I'm not sure if my question pertains to hardware RAID in general, or to the specific RAID controller I'm working on. Either way it is the Dell SAS 6/iR (this is an LSI sas1068e chipset). I simply want to: remove a set of striped (RAID 0) disks from this RAID controller in a server put in another set of disks, and create a RAID 1 array (or create a new 'virtual disk', as they call it in the SAS 6/iR manual) Do stuff with the new RAID 1 array Have the option of putting back the old set of disks (the RAID 0 striped ones) I am quite sure this is possible, but I need some form of reliable, evidence-based answer as it's for a client of mine, and I need to migrate their data safely. The question: can I actually do the above? Does the RAID configuration get stored on the disks themselves, or in the hardware controller? Is any data stored in the hardware controller? If there is any chance I cannot completely restore operation of the first set of disks I removed, then I need to know about it! The manual alludes to the answer to this question (see page 45 of this document), and talks about activating an array of disks. I just need someone to confirm I can definitely do the above. See, simple question, right? :)

• Removing expired self-signed certificate in IE9 (created with IIS7.5)

  - by Itison

  Over 1 year ago, I created a self-signed certificate in IIS 7.5 and exported it. I then installed it for IE9 (it may have been IE8 at the time), which worked fine until a year later when the certificate expired. I have put this off, but today I created a new self-signed certificate in IIS, exported it, and attempted to install it in IE9. The problem is that for whatever reason, IE cannot seem to forget about the old, expired certificate. Here's what I tried initially: Accessed my ASP.NET application and see the Certificate error. Clicked "View certificates". Clicked "Install Certificate" and then Next/Next/Finish. At this point, it says the import is successful, but it still only shows the expired certificate. I've tried simply double-clicking on the exported certificate on my desktop. Initially I chose to automatically select the certificate store, but then I tried it again and manually selected "Trusted Root Certification Authorities". I've also tried dragging/dropping the certificate over an IE window and clicking "Open". The process is then exactly the same as it is if I had double-clicked on the certificate, but I had hoped that this would somehow specifically tell IE to use this certificate. I tried opening MMC and with the Certificate snap-in, confirmed that the new certificate was added under "Trusted Root Certification Authorities". It was also under my "Personal" certificates (I guess this is where it goes by default). Nothing worked, so I went through every folder in MMC and deleted the expired certificate. I also deleted the expired certificate in IIS. Nothing has worked. Any ideas? I see no clear resolution and I can't seem to find any posts related to this issue.

• How to keep multiple servers in sync file wise?

  - by GForceSys

  I'm currently managing a cluster of PHP-FPM servers, all of which tend to get out of sync with each other. The application that I'm using on top of the app servers (Magento) allows for admins to modify various files on the system, but now that the site is in a clustered set up modifying a file only modifies it on a single instance (on one of the app servers) of the various machines in the cluster. Is there an open-source application for Linux that may allow me to keep all of these servers in sync? I have no problem with creating a small VM instance that can listen for changes from machines to sync. In theory, the perfect application would have small clients that run on each machine to be synced, which would talk to the master server which would then decide how/what to sync from each machine. I have already examined the possibilities of running a centralized file server, but unfortunately my app servers are spread out between EC2 and physical machines, which makes this unfeasible. As there are multiple app servers (some of which are dynamically created depending on the load of the site), simply setting up a rsync cron job is not efficient as the cron job would have to be modified on each machine to send files to every other machine in the cluster, and that would just be a whole bunch of unnecessary data transfers/ssh connections.

• Wires from fan on side panel - where do they connect?

  - by Mick

  The side panel of my desktop PC has a small fan built in. There were two wires, one red one black that connected inside the PC. Unfortunately I had the bolts removed and the side door fell off ripping the cables such that the main length of cable remains attached to the fan. So there must be two short stubs of broken cable somewhere - but I can't find them! Any ideas where I should look? I can't see anything on the motherboard. the PC is running perfectly well - but I now have the side open to make sure the air can circulate. EDIT: The motherboard appears to be an "Asus P6T SE" EDIT: The manual shows the location of two "chassis fan" connectors. One is being used by a big chassis fan on the back face of the PC (underneath the pwer supply). The other appears to be unused - there is no stub of a connector with wires - its just the bare pins sticking directly out of the motherboard. There is also an unused "pwr_fan" connector. Would it be ok to simply connect the black and red wires from the fan to the black and red parts of a molex adapter?

• Why won't sql server express 2008 service restart after I enable TCP/IP Protocol?

  - by John

  Whenever I enable TCP/IP connections on my SQL Server Express 2008 database server running on Windows XP SP3, I cannot restart the service, it simply states "The request failed or did respond in a timely fashion". Any suggestions of what I may have configured incorrectly? [update] Here is the applicable part of the Error Log: MSSQL$SQLEXPRESS Server failed to list on 'any' 3060. Error: 0x2747. To proceed, notify you system administrator. MSSQL$SQLEXPRESS TDSSNIClient initialization failed with error 0x2747, status code 0xa. Reason: Unable to initialize the TCP/IP listener. An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full. MSSQL$SQLEXPRESS TDSSNIClient initialization failed with error 0x2747, status code 0x1. Reason: Initialization failed with an infrastructure error. Check for previous errors. An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full. MSSQL$SQLEXPRESS Could not start the network library because of an internal error in the network library. To determine the cause, review the errors immediately preceding this one in the error log. MSSQL$SQLEXPRESS SQL Server could not spawn FRunCM thread. Check the SQL Server error log and the Windows event logs for information about possible related problems.

• Routing connections through VPN based on hostname (not IP range)

  - by Michal M

  This bugs me immensly. I need to connect to client's network through VPN. But I definitely do not want to send all the traffic through client's network so this option is out of question. What I need basically is for the OS to know that all client's network subdomains (*.example.com) need to go through the VPN connection. I tried a couple of options: Changing order of services and setting the VPN on top, but this works the same as "Send all traffic over VPN connection". Using "VPN on Demand" option from network advanced options, but this feature is quite rubbish to be honest. Seems to work only in Safari (?!) and it doesn't route the connection, but it basically triggers the OS to connect to the selected VPN. The reason I need it to work based on hostnames rather than IP range is simple - my client has a lot of servers inside his network and it's impossible for me to remember all IPs. They are all within a range, but this doesn't help me remembering. Another option would be to put the VPN connection on the bottom of network services and untick "Send all traffic..." and then put all known hostnames in hosts file, but considering there could be hundreds of servers (therefore hostnames and ips too) it ridiculous job. And if new server appears on the network I'd need to edit the hosts file again. Sisyphean labours. However this works on Windows very simply. If a hostname is not available through default network interface, then it seems to try VPN connection and this works brilliantly. So, how can I achieve that on Mac, then? I know client's internal DNS addresses if that is of any help (like directing a certain domains through a different DNS)? PS. Using latest version 10.6.6. PS2. I am using VPN to access intranet, version control servers (svn://), samba shares and for SSH access to servers.

• Windows 7 Icons, Buttons, and Tabs corrupted...Professional 32-bit

  - by xhyperx

  The other day, about two or three ago, I was simply typing in a Microsoft Word document when my screen froze. After a few moments, it went black...I thought it was my vid hardware (dual nVidia 9800 GTs). Anyway, I did a hard reboot, and chose to Start Normally. The system blue screened telling me there was a failure in the Memory Manager. So then I thought maybe a RAM failure or vid memory failure. I attempted reboot again, this time I got presented with the option to repair windows...so I went with that. The repair app finished and did an auto reboot. This time I got all the way back to my desktop where in a matter of a about 30 seconds, the system blue screened again and pointed to the Memory Manager as the area of cause. Again I rebooted, the repair thingy came up again and I allowed it to do its thing. Deciding if the same failure occured I'd begin pulling hardware to see at what point I may have found the possibly defective party. However, this time it rebooted, I got back to desktop and no crash. All looked well, untill I looked at the baloon messages when hovering over the System Bar icons. Also when I opened any of my browsers, the tabs had no text, and any window that pops up that has regular buttons (OK, Cancel, etc., etc.) looks weird. The buttons are really really long and have no text. So it seems like the system is once again running smoothly, however something has gotten corrupted.. something relating to drawing basic windows user interface objects. Help...all ideas are respected and appreciated. Have a great day everyone!
