  • Debugging IO limitation

    - by Martin F
    I have a Fedora box with some severe IO limitations which I have no idea how to debug. The server has a Areca Technology Corp. ARC-1130 12-Port PCI-X to SATA RAID Controller with 12 7200 RPM 1.5 TB disks and a Marvell Technology Group Ltd. 88E8050 PCI-E ASF Gigabit Ethernet Controller. uname -a output: 2.6.32.11-99.fc12.x86_64 #1 SMP Mon Apr 5 19:59:38 UTC 2010 x86_64 x86_64 x86_64 GNU/Linux The server is a file server running Nginx with the stub status module enabled, so I can see the current amount of connections. The problem present itself when I have a high number of simultaneous connections in a writing state. Usually around 350, at this very moment it's at 590 and the server is almost unusable and stuck at 230mbit/s. If I run stop and hit 1 to see CPU core usages I have all 4 cores with around 99% io wait, if I run iotop the nginx workers are the only processes producing any read load, currently at around 25MB/s. I have each of the workers bound to their own core. Initially I figured it was just the disks being bugged. But I've run fscheck and smartmontools checks and found no errors. I also ran an iozone test which you can see the result of here: http://www.pastie.org/951667.txt?key=fimcvljulnuqy2dcdxa Additionally, when the amount of connections are low I have no problem getting a good speed. If I wget over the local network it easily hits 60MB/sec. Right now I just tried putting a file in /dev/shm, then I symlinked a file from the public dir to it and used wget over the local network and only got 50KB/s. Also, if I try to cp /dev/shm/test /root/test it quickly copies around 740MB and then slows down HEAVILY. Again with iotop reporting 99% iowait. I'm not really sure how to go about figuring out what the problems are. It could be a natural disk limitation but then the file from /dev/shm ought to transfer so it seems there's a network limit, but that's fine when there's not many connections. Perhaps it's a TCP stack problem but I really have no idea how to check that. Any suggestions on how to proceed with debugging would be very welcome. If additional information is required then let me know and I'll try to get it. Thanks.

  • Configuring Apache reverse proxy

    - by Martin
    I have loadbalancer server and edges. I am trying to configure reverse proxy in order to hide the backend servers PL1,2,3. PL 1,2,3 are not located in same subnet. They are located in different locations. PL1 Lb1 -> PL2 PL3 I tried to configure Apache reverse proxy but it is not sending request to PL1,2,3. Reverse proxy worked only when I configured apache to send request to local server on other port. ProxyRequests Off <Proxy *> Order deny,allow Allow from all </Proxy> ProxyPass /PL1 http://PL1server.com/ ProxyPassReverse /PL1 http://PL1server.com/ The above configuration did not worked. Could you help me to solve the issue. Or is there other proxy types like Squid,Socks5 to solve this issue. Does the reverse proxy fails if we use IP address or domain URL in ProxyPass and ProxyPassReverse ?

  • User given a login prompt when closing Word documents after viewing them in IE7

    - by Martin Owen
    When using IE7 to view Word documents on our CRM system (an ASP.NET 2.0 application running on Windows Server 2003 and IIS 6 and using Windows authenticaton) I'm finding that a prompt appears when the user closes the document. The Word document is originally opened by clicking a link in the CRM system. Are there permissions that I can set on the folder containing the Word documents to prevent this prompt? I've already tried only allowing the Read permission for the Users group (I've left Administrators with Full Control.) If there's another solution to this without using permissions please let me know. UPDATE: I ran Fiddler as suggested by JD and here is the output from the two responses after the request for the document. The first seems to be a DAV response and the second is the authentication request. How do I prevent the DAV response and just return the .doc on the server? OPTIONS / HTTP/1.1 Translate: f User-Agent: Microsoft Data Access Internet Publishing Provider Protocol Discovery Host: <REMOVED> Content-Length: 0 Connection: Keep-Alive Pragma: no-cache X-NovINet: v1.2 HTTP/1.1 200 OK Date: Thu, 18 Feb 2010 13:37:36 GMT Server: Microsoft-IIS/6.0 X-Powered-By: ASP.NET MS-Author-Via: DAV Content-Length: 0 Accept-Ranges: none DASL: <DAV:sql> DAV: 1, 2 Public: OPTIONS, TRACE, GET, HEAD, DELETE, PUT, POST, COPY, MOVE, MKCOL, PROPFIND, PROPPATCH, LOCK, UNLOCK, SEARCH Allow: OPTIONS, TRACE, GET, HEAD, COPY, PROPFIND, SEARCH, LOCK, UNLOCK Cache-Control: private ------------------------------------------------------------------ OPTIONS /docs/ZONE%20100-105.doc HTTP/1.1 Translate: f User-Agent: Microsoft Data Access Internet Publishing Provider Protocol Discovery Host: <REMOVED> Content-Length: 0 Connection: Keep-Alive Pragma: no-cache X-NovINet: v1.2 HTTP/1.1 401 Unauthorized Content-Length: 83 Content-Type: text/html Server: Microsoft-IIS/6.0 WWW-Authenticate: Basic realm="<REMOVED>" X-Powered-By: ASP.NET Date: Thu, 18 Feb 2010 13:37:36 GMT ------------------------------------------------------------------ UPDATE 2: I found a potential workaround for the problem via this post: http://forums.iis.net/p/1149091/1868317.aspx. I moved all of the documents that are being requested into a folder outside of the web root, and created a virtual directory for it (also outside of the web root). When I followed a link to one of the documents in IE and then closed the document I wasn't presented with a login prompt. I should point out that I'm not using FPSE, unlike the person in the forum post. Ideally I don't want to have to put the documents in a separate virtual directory, but this is the simplest solution I've found so far.

  • Windows errors, how do I find root cause and fix it? Getting several errors

    - by Eric Martin
    My server is having issues and not responding to customer's https requests. I checked the event viewer and found several errors. These two are listed a couple of times: WINS encountered a database error. This may or may not be a serious error. WINS will try to recover from it. You can check the database error events under 'Application Log' category of the Event Viewer for the Exchange Component, ESENT, source to find out more details about database errors. If you continue to see a large number of these errors consistently over time (a span of few hours), you may want to restore the WINS database from a backup. The error number is in the second DWORD of the data section. And this one: An error occured while using SSL configuration for socket address 0.0.0.0:444. The error status code is contained within the returned data. SQL Server is not ready to accept new client connections. Wait a few minutes before trying again. If you have access to the error log, look for the informational message that indicates that SQL Server is ready before trying to connect again. [CLIENT: xxx.xxx.xxxx.xxx] I also found this in the event viewer but the computer has been restarted since this message and I have not seen it again. Configuring the Page file for crash dump failed. Make sure there is a page file on the boot partition and that is large enough to contain all physical memory. This is my virtual memory settings: I'm not familiar with WINS so I wasn't sure if that is where I start or how to resolve it. Is the WINS error causing the other problems or should I be looking somewhere else?

  • bash and arithmetic comparison: double quotes or not?

    - by Martin
    when comparing two integers in bash, do we have to put double quotes ? In the official document http://tldp.org/LDP/abs/html/comparison-ops.html I can read that double quotes should appear every time... But what is the differences in the following examples: [ "$VAR" -eq "1" ] [ $VAR -eq "1" ] [ "$VAR" -eq 1 ] [ $VAR -eq 1 ] As I am curious, a took a look at Ubuntu init scripts in /etc/init.d and there are many usage of arithmetic comparison in it, at least [ "$VAR" -eq "1" ] and [ $VAR -eq 1 ] are used... but it seems no one really "knows" what is the official way to do it. Thanks !

  • How do I resolve certificate errors on HP blade center

    - by Martin Hilton
    I'm trying to sort out the ssl certificate errors that we get when trying to manage our HP c7000 blade enclosures. To that end I have created a signing certificate and imported it into the browser. In Onboard Administrator I created a certificate signing request, which I signed with my CA and then uploaded the certificate. This worked perfectly, and I no longer get any SSL errors when connection to Onboard Administrator. The problem comes when trying to connect through Onboard Administrator to the iLo on the blades themselves. Done by clicking on the "Web Administration" link. Onboard Administrator links to the blade with it's IP address rather than host name. But the certificate signing request that iLo creates uses the host name. Even when this certificate is signed the browser still complains it is for the wrong domain. I either need to be able to get Onboard Administrator to connect to the blades using host name rather than IP address, or get a certificate signing request which contains the IP address as the CN rather than the host name. It doesn't particularly matter which. Does anybody know how to configure this?

  • Can't connect to workgroup

    - by Bonyfus Martin
    I have two computers in my workgroup. My laptop has Windows 7 on it and desktop has Windows Server 2008 on it. I can ping and connect to the Windows Server 2008 from my laptop but I cannot ping or connect to my laptop from Windows Server 2008. Both computers are in the same workgroup, and their IP addresses use the same subnet mask. Does anyone know why I cannot connect to my laptop from the Windows Server 2008 machine?

  • Fonts doesn't render in Chrome or IE in Windows Server 2008

    - by Martin Carlsson
    When I visit, for example, http://www.bolagsverket.se from a user account on this Windows 2008 Server, Chrome displays the site but all the text is gone. When I try in IE it's even worse, it doesn't even load the page, I jsut end up with this: http://dl.pixelstore.se/image/0y1f0y0w1J39 The fonts used for this site is (from CSS): font-family:Frutiger,Frutiger Linotype,Univers,DejaVu Sans Condensed,Liberation Sans,Nimbus Sans L,Geneva,Helvetica Neue,Helvetica,Arial,Tahoma,sans-serif If I edit the CSS through Chrome Developer Tools, and erase all fonts until Arial it suddenly works. The strange thing is that everything works fine from the administrator account, it's just (all) the user accounts that doesn't work. My guess is that Chrome/IE is asking for the fonts but somehow they are restricted in the user account. Instead of just ignoring the fonts they can't find they try to render them anyway. Any clue?

  • Error upgrading Ubuntu server from Intrepid to Jaunty

    - by Martin
    I'm trying to upgrade an old ubuntu server from 8.10 (Intrepid) to 9.04 (Jaunty). But it fails. root@server1:/# do-release-upgrade Checking for a new ubuntu release Failed Upgrade tool signature Failed Upgrade tool Done downloading extracting 'jaunty.tar.gz' Failed to extract Extracting the upgrade failed. There may be a problem with the network or with the server. Does anyone have an idea why I get this error and how to fix it? UPDATE: I think i might have tracked the problem down. My /etc/update-manager/meta-release looks like this: [METARELEASE] URI = http://changelogs.ubuntu.com/meta-release URI_LTS = http://changelogs.ubuntu.com/meta-release-lts URI_UNSTABLE_POSTFIX = -development URI_PROPOSED_POSTFIX = -proposed If i go to http://changelogs.ubuntu.com/meta-release it has this info for Jaunty: Dist: jaunty Name: Jaunty Jackalope Version: 9.04 Date: Thu, 23 Apr 2009 12:00:00 UTC Supported: 0 Description: This is the 9.04 release Release-File: http://archive.ubuntu.com/ubuntu/dists/jaunty/Release ReleaseNotes: http://changelogs.ubuntu.com/EOLReleaseAnnouncement UpgradeTool: http://archive.ubuntu.com/ubuntu/dists/jaunty-proposed/main/dist-upgrader-all/0.111.8/jaunty.tar.gz UpgradeToolSignature: http://archive.ubuntu.com/ubuntu/dists/jaunty-proposed/main/dist-upgrader-all/0.111.8/jaunty.tar.gz.gpg Those links starting with archive.ubuntu.com are broken since jaunty is EOL. I guess i could fix this by copying this file, replacing "archive" with "old-releases", host the modified file somewhere and change the url in the meta-release file. Is this a good solution or will it make me run into worse problems?

  • Links not opening in Windows 8 applications

    - by Martin Brown
    I have just upgraded my laptop from Windows 7 Ultimate with IE9 to Windows 8 with IE 10. When ever I try to open a web link in an application nothing happens. For example in the Windows 8 mail application it makes the email address in an email look like a link. When I click on these with the mouse the link changes to look like I have clicked on it, but aside from that nothing happens. I have tried making sure that IE 10 is my default web browser and been into IE10's settings and associated it with all the usual file types, but still no success. Has anyone got any ideas what might be causing this? I have a feeling this started when the Browser Choice update ran. I couldn't select which browser to install in that either. The install buttons just flashed when I clicked them and then nothing. PS I would have added an IE10 tag to this post, but apparently I don't have the reputation required to do so.

  • Is there a "rigorous" method for choosing a database?

    - by Andrew Martin
    I'm not experienced with NoSQL, but one person on my team is calling for its use. I believe our data and its usage isn't optimal for a NoSQL implementation. However, my understanding is based off reading various threads on various websties. I'd like to get some stronger evidence as to who's correct. My question is therefore, "Is there a technique for estimating the performance and requirements of a certain database, that I could use to confirm or modify my intuitions?". Is there, for example, a good book for calculating the performance of equivalent MongoDB/MySQL schema? Is the only really reliable option to build the whole thing and take metrics?

  • black backgrounds appear grey on gnome-terminal

    - by Martin DeMello
    Running gnome under Ubuntu Lucid $ env | grep TERM TERM=xterm COLORTERM=gnome-terminal I had to edit both my .muttrc and my vim colorscheme to change the background color from black to none in order to get a proper black background (or, more accurately, to retain the terminal's default black background). Setting it to black resulted in a dark grey background. This only happens with gnome-terminal; konsole, xterm and rxvt are fine.

  • Help: Best way to do a TV-out in 7300GT Nvidia video card?

    - by Martin Ongtangco
    I'm planning to recycle my old PC and build a Media Center using an open-source (C#) software called MediaPortal. My old PC has a GeForce 7300GT with a TV-out plug built-in. When I tested it last night, it wouldn't detect my JVC tv (CRT) using the current drivers. I even purchased a new copper-based TV-Out to RCA cable. I searched all 3 AV channels. The video card has 3 output ports: 2 DVI & 1 s-video. I used the s-video with a S-Video to RCA out cable. I swapped between PAL & NTSC So what I did was I downloaded the first version of an Nvidia driver for 7 series cards, but still even with the old console, it couldn't detect the TV. I'm running out of viable ideas. Anyone here had the same problem and fixed it? Any suggestion is appreciated. Thank you!

  • Is an Intel Atom D525 suitable to run MythTV

    - by Martin Thompson
    I have an oldish netbook with an Atom N450 (1.6GHz, 512KB cache) - I've been using it to experiment with MythTV, but it seems really slow, even just to work through the menus! Seconds, sometimes 10 or 20s, to load a new menu. Admittedly from a remote backend, but my older Core1 based laptop seems to be fine with the same setup. I was hoping to use one of the so-called "nettop" devices which currently seem to be D525-based (1.8GHz, 1MB cache) - is double the cache really going to make that much difference? Or has the internal architecture of the Atom moved on leaps and bounds in between? Given that I design non-Intel embedded computers for a living I was hoping to get lots of hardcore architecture detail from the Intel website, so I could see for myself, but I can't find it! So: will a D525 be fast enough to run a MythTV backend/frontend combined box?

  • Macros Excel 2007 - extracting data

    - by Martin
    Im trying to extract certain data from a cell and trying to put it somewhere else within the same cell. Any suggestions? EDIT I have several text strings in ONE cell (a date, a part number and a color). The format looks like this 100906 PBO5 BLUE. The date is always the same number of characters but the part number could be 2, 3 or 4 characters. I want to move the date to the position after the color so it looks like this PBO5 BLUE 100906. I have over 1,000 records so I don’t want to do this manually.

  • rsync over SSH with cron in osx-environment

    - by Martin
    I want to automatically download files and folders from a Linux server to which I have an SSH (and FTP) account. The files shall be downloaded on a regular basis (I suppose a cron is the right tool to do so) onto an OS X machine. I tried the following rsync command, which works fine: rsync -avzbe ssh [email protected]:/www/htdocs/something/somefolder /Users/me/folder/foo/ However I have to enter the account's password every time (the SSH account on the server machine). The server is a managed one and I'm afraid I can't change the password. Here are my questions: How do I bypass the entering of the password by storing it somewhere How do I automate this then correctly?

  • MediaPortal crash when scanning my TV Channels

    - by Martin Ongtangco
    Hello, I tried installing MediaPortal (http://www.team-mediaportal.com) on my old system. I installed & tried both beta & stable releases: Here's the old system specs: Windows XP SP3; 512mb DDR; 80GB IDE; K-World PVR-TV7131 Analog TV-Tuner; Inno3d FX5500 128mb 64bit; When scanning through the TV-Server, it crashes. I don't know if the incompatibility comes from the hardware or the OS, but my TV Tuner's own Media center app works well. For now, that's what im using. Anyone here familiar with MediaPortal? Thanks!

  • Can't use sudo on ubuntu

    - by martin.malek
    After update and reboot I get 'user is not in the sudoers file. This incident will be reported.' when trying to call sudo. The problem is that I don't have a GRUB with revovery option. I try to boot from live cd but I'm not able to access the system partition, only the partition with grub. Can I somehow enable the recovery mode in GRUB? Or boot throw the live CD from first hard drive with some option for that?

  • I disconnected my cellphone while transferring files to its Mini SD card. Now the files aren't there

    - by Martín Fixman
    I use Ubuntu 9.10, and the MiniSD card shows as having the space used as if there were files. Baobab (the disk usage analyzer) shows that the card only has 118 MB used (of the 401 Ubuntu claims there are). Of course, I already tried the obvious (rebooting the phone, adding and removing files, etc.), but I don't want to format my card, because I still have some files on it, the transfer to my computer is slow, and because I use an old wire it fails often.

  • Latitude E6410 - Screen flickering on Windows 8

    - by Martin
    On Windows 8, my Latitude E6410 screen (1440x900 - 60Hz - NVidia NVS3100M) is flickering. If I turn off the laptop for 30 minutes and turn it back on, there's no flickering but it eventually start again after 10-15 minutes. The flickering seems more present at the top and bottom of the screen. I already updated the graphic card drivers, bios, etc. Nothing seems to fix the issue. To prove that it isn't a hardware issue, when I reinstalled Windows 7 I couldn't reproduce the issue. Any idea what could cause this?
