  • How do I screen-capture an inactive window?

    - by Wassasin
    How can I screen-capture an inactive (minimized / on another workspace) window in Ubuntu? Applications like ImageMagick's import are only able to capture active windows. When attempting to capture an inactive window, I get the following message: unable to read X window image `<id>': Resource temporarily unavailable @ error/xwindow.c/XImportImage/5023. Might be able to do this using Compiz, as it is able to render previews of inactive windows. Furthermore, in my specific case, the window I want to capture is run in a Wine Explorer-container. Inside that container the application is always active.

  • how to serialize function depending on what instance of object calls it, if same instance call in a thread then do serialize else not

    - by LondonDreams
    I have a function which fetches and updates some record from db and I am trying to make sure each if the function is called by same instance of object(same Or different thread) then function should behave synchronized else its a call from different object instance function need not to be synchronized. I have tried it use a lock per client. That is, instead of synchronizing the method directly using explicit locking through lock objects using Map. function is like :- getAndUpdateMyHitCount(myObjId){ //go to db and get unique record by myObjId //fetch value , increment , save update } And this function may get call is same thread by different Or same object instance But as fetching and matching from Map is slow , Is there other optimized way to do this ? Found similar at this Question but dont feel that is optimized

  • Ubutnu 12.04 mdadm inactive

    - by user32274
    For a while now, my RAID 5 has ceased to work. Everytime I tried "madm --detail /dev/md127", its states all the drive and drive info, but that two of the drives have been removed. After some restarts, doing the same thing, i am getting /dev/md127 does not appear to be active. When I go into DiskUtil, I can see all 6 Hard Drives healthy and present, and i can see the Raid 5 at the bottom under Multi-disk Devices. However, the Raid says 0.0kb, and is not active. Please help and let me know how to proceed from here. I would really like to avoid rebuilding the RAID, especially because all 6 drives seem to be healthy and present. Thanks so much.

  • jQuery event not working after load

    - by Shina
    $(document).ready(function(){ $(function() { $('a.ajaxload').live('click', function(e) { var url = $(this).attr('href'); $('#desktopcontainer').load(url); // load the html response into a DOM element e.preventDefault(); // stop the browser from following the link }); }); $(function() { $(".accordion .accordion-tabs .tab").each(function(){ $(this).click(function(){ if ($(this).hasClass('tab')){ $(this).removeClass('tab'); $(this).addClass('active'); }else{ $(this).removeClass('active'); $(this).addClass('tab'); } $(this).next().slideToggle('slow'); return false; }); }); }); }); My tab works fine but after I click the "a.ajaxload" to add a content to the page, then my tab doesn't respond anymore. Can anyone please tell me where the problem is? Thank you in advance.

  • Best way to rename existing unique field names in database?

    - by Rajdeep Siddhapura
    I have a database table that contains id, filename, userId id is unique identifier filename should also be unique table may contain 10000 records When a user uploads a file it should be entered in database with given rules: If there is no record with same filename, it should be added as it is (Ex. foobar.pdf) If there is record with same filename, it should be added as uploadedName(2).ext (foobar(2).pdf) If there are n records with same base filename (foobar), it should be added as uploadedName(n+1).ext (foobar(20).pdf) Now if foobar(2).pdf is uploaded, it should be added as foobar(2)(2).pdf & so on This pattern needs to be followed because the file is already being uploaded at client side using ajax before sending the details to server and the file hosting service follows the above rules to name the files. My solution: maintain a file that contains all the names and the number of times it has occurred. if a filename that exists in file is entered, increase occurrence count and new name is generated, else add to it to file if the new name generated is in database, add it to file and generate new name

  • multiple monitor, ATI EyeFinity vs NVidia Mosaic on HDMI

    - by user1531897
    i have been googling much for answer but only someone with real experience can help here. my aim is to have 5 monitors connected to one computer in 2x2 full screen on all 4 monitors (video wall) with same resolution, 4xfullHD for example, plus one -5th monitor as controling. Ati have example picture of this configuration here. I have no gaming nor 3d needs here. Simple desktop applications plus video streams. So because graphic cards for this are expensive, i need to find out before buying pros and cons of 2 possible solutions (1) Ati Eyefinity capable card(s) ...and (2) Nvidia Quadro/NVS card(s) with mosaic and/or nvidia surround technology. For example i can find that current good cards for this can be: Ati's 7870 eyefinity6 card, link here pros: one card can handle all 5 displays, cons: active DP adapters needed (sometimes with aditional usb-powering complication) Nvidia Qudro NVS 450, link here Both cards have DisplayPorts as outputs (my targets are HDMI displays), but as far i saw information is that Eyefinity needs "active DP-DVI/hdmi adapters" for outputs and they are little expensive...? Does nvidia have this limitation (active adapters) ??? And final question, is Ati Eyefinity still better for this purpose than Nvidia-mosaic by someone's real experience there.

  • Fetching e-mails into Redmine via IMAP

    - by Danilo Bargen
    I'm trying to fetch e-mails into Redmine via IMAP. The e-mails I'm generating look like this: FooBar Ltd 123456 http://example.com/Foobar-Ltd-123456.html Project: backend Tracker: Dataerror Beschreibung: This is the description =========================== CLIENT_IP: 192.168.1.215 HTTP_USER_AGENT: mozilla/asdfjköl I try to fetch them into Redmine via this command: rake -f /var/www/projects/redmine/Rakefile redmine:email:receive_imap \ RAILS_ENV="production" host=example.com port=993 ssl=true username=redmine \ password=1234 project=myproject tracker=other \ allow_override=project,tracker,category,priority \ move_on_success=read move_on_failure=failed But the e-mails get moved into the failed folder. I had this setup running some time ago with a different e-mail generator but pretty much the same template, and I can't figure out why it's not working. The permissions seem to be OK too. In order to further debug this issue, I need some logfiles. Are there any logfiles written by this command? Or are there any other suggestions to solve this issue?

  • swapping or trashing with vast amounts of unmapped pagecache

    - by Marco
    I'm using kubuntu jaunty (i386 32bit), kernel 2.6.28-13-generic. I've 4Gb of RAM, of which only 3317Mb are seen by the system (I guess because of the 32bit system). I'm seeing that the pagecache utilization is continually growing, up to the point that the system is unusable (after a few days). This happens also when I don't do anything (all user applications closed and the bare minimum of services enabled). If enabled, the system starts to use swap space (using it all in the end). Even if swap is disabled, disk activity becomes continuous, with the system unresponsive. For example, right now the system is working (albeit a tad slow), with only firefox and wing ide running, and I have 2Gb cached with only 45Mb mapped: $ free total used free shared buffers cached Mem: 3346388 3247328 99060 0 8416 2117980 -/+ buffers/cache: 1120932 2225456 Swap: 2144668 519448 1625220 $ cat /proc/meminfo MemTotal: 3346388 kB MemFree: 97128 kB Buffers: 7872 kB Cached: 2120224 kB SwapCached: 413860 kB Active: 2304596 kB Inactive: 865984 kB Active(anon): 2279168 kB Inactive(anon): 830236 kB Active(file): 25428 kB Inactive(file): 35748 kB Unevictable: 32 kB Mlocked: 32 kB HighTotal: 2492940 kB HighFree: 5456 kB LowTotal: 853448 kB LowFree: 91672 kB SwapTotal: 2144668 kB SwapFree: 1625244 kB Dirty: 84 kB Writeback: 0 kB AnonPages: 629304 kB Mapped: 45768 kB Slab: 45600 kB SReclaimable: 21756 kB SUnreclaim: 23844 kB PageTables: 4468 kB NFS_Unstable: 0 kB Bounce: 0 kB WritebackTmp: 0 kB CommitLimit: 3817860 kB Committed_AS: 3735020 kB VmallocTotal: 122880 kB VmallocUsed: 9352 kB VmallocChunk: 66600 kB HugePages_Total: 0 HugePages_Free: 0 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 4096 kB DirectMap4k: 16376 kB DirectMap4M: 888832 kB If I try to drop the caches, little happes: # sync ; echo 3 > /proc/sys/vm/drop_caches ; free total used free shared buffers cached Mem: 3346388 3220580 125808 0 3020 2100600 -/+ buffers/cache: 1116960 2229428 Swap: 2144668 519356 1625312 Right now I've vm.swappiness = 5, but I've tried also with 0 and 1 (without noticeable differences).

  • Issues with doing a P2V on Exchange 2007

    - by PokermUNKEE
    I shutdown all Exchange services on the physical box and did a convert. Everything converted fine. Server booted up no issues and I could receive email from the outside world with no issues. But I am unable to send emails internally or externally. They just sit in the Outbox. I also disabled the DHCPClient service as I didn't want the server to get an IP address from DHCP when it first came online. It came online with no IP, then I used console to assign the correct static IP address (same one on the physical server) and rebooted. I ran the Exchange Troubleshooting Agent and it gave me the following errors: The value for the '\MSExchangeIS Mailbox\Messages Queued For Submission' counter on server exchange is greater than zero (average value is 8.8) and it appears that 'MSExchangeMailSubmission' is failing to submit messages to at least one computer with the Hub Transport server role installed over the last minute. Found 1 computers with the Hub Transport server role installed in the same Active Directory site as server exchange using local Active Directory site GUID 'ce8a4367-1bf6-4825-9cac-c4e2b115c450'. Check Local Active Directory Site Hub Transport Server Role Health (Mailflow_CheckLocalBhHealth1.1.1.1.1.1.1.1) I have one Exchange server with all the roles on it. Has anyone see this before when doing a convert? Please help :(

  • Cisco Spam Blocker, Iron Port, Lotus Domino, Integration Help

    - by NickToyota
    Hi serverfault universe, I work for a medium sized (roughly 200 user) company. We are attempting to intagrate our new Cisco Spam Video Blocker (ironport) device into our network so that it acts as an incoming filter then passes it off to our Lotus domino mail server. And also vise versa. The way our network is setup currently has an mx record pointing to our Domino mail SMTP incoming server which is currently setup to be an inbound gateway and filter (using symantec domino mail software). We want to replace the inbound gateway with the ironport. Our company has also invested in a pool of external IP addresses which I believe has been currently assigned to our web, email, servers. What would the proper course of action be to successfully integrate the device be? Mx record change? Replace the domino gateway completely with the ironport? We attempted to set the ironport device to the external IP of what our mx record is pointing to without much success. Any help on proper setup would be greatly appreciated.

  • How does SELinux affect the /home directory?

    - by Matt Solnit
    Hi everyone. I'm migrating a CentOS 5.3 system from MySQL to PostgreSQL. The way our machine is set up is that the biggest disk partition is mounted to /home. This is out of my control and is managed by the hosting provider. Anyway, we obviously want the database files to be on /home for this reason. With MySQL, we did the following: Edited my.cnf and changed the datadir setting to /home/mysql Added a new "File type" policy record (I hope I'm using the right terminology) to set /home/mysql(/.*)? to mysqld_db_t Ran restorecon -R /home/mysql to assign the labels and everything was good. With PostgreSQL, however, I did the following: Edited /etc/init.d/postgresql and changed the PGDATA and PGLOG variables to /home/pgsql/data and /home/pgsql/pgstartup.log, respectively Added a new policy record to set /home/pgsql/pgstartup.log to postgresql_log_t Added a new policy record to set /home/pgsql/data(/.*)? to postgresql_db_t Ran restorecon -R /home/pgsql to assign the labels At this point, I still cannot start PostgreSQL. pgstartup.log says: # cat pgstartup.log postmaster cannot access the server configuration file "/home/pgsql/data/postgresql.conf": Permission denied The weird thing is that I don't see any messages related to this in /var/log/messages or /var/log/secure, but if I turn off SElinux, then everything works. I made sure all the permissions are correct (600 for files and 700 for directories), as well as the ownership (postgres:postgres). Can anyone tell me what I am doing wrong? I'm using the Yum repository from commandprompt.com, version 8.3.7. EDIT: The reason my question specifically mentions the /home directory is that if I go through all these steps for any other directory, e.g. /var/lib/pgsql2 or /usr/local/pgsql, then it works as expected.

  • Can ping IP address and nslookup hostname but cannot ping hostname

  • Multiple contacts with shared information

    - by Keith Thompson
    Background: I currently have several hundred contacts, synchronized between a Microsoft Exchange server and several mobile devices. I also save exported copies of the contacts in .vcf format. Is there a good way (application, file format, whatever) to maintain contacts with shared information? A very common scenario is that I have contacts for two or more people who live in the same house, for example: John Doe 123 Main Street, Anytown USA Home: 555-555-1111 Work: 555-555-2222 Mobile: 555-555-3333 E-mail: [email protected] Jane Doe 123 Main Street, Anytown USA Home: 555-555-1111 Work: 555-555-4444 Mobile: 555-555-5555 E-mail: [email protected] As you can see, both contacts have the same home address and phone number, but distinct names and work and mobile phone numbers. (Other information might also be either shared or distinct.) The applications and file formats I'm familiar with don't seem to have a good way to deal with this. If I use a single "John & Jane Doe" contact for both, it's difficult to distinguish the distinct information (if I want to call Jane's mobile phone rather than John's). If I use a separate contact for each, I have to remember to update both of them (or all of them for N 2) when they move or change their home phone number. An ideal solution would let me create a record containing information for their household, and have each of their contact records contain a reference to the household record, so that when I view John's contact record I see both shared and distinct information. Is there anything out there that has good support this kind of thing? (I would think there would be, since it's a very common scenario.) (I suppose I could roll my own system that generates merged .vcf files from some extended format, but that wouldn't play well with synchronizing across multiple devices.)

  • How to get the permissions right for /dev/raw1394

    - by Mark0978
    I recently upgraded one of my ubuntu machines to Karmic and I'm having trouble getting the permissions of /dev/raw1394 set to 0666. They only thing this machine is used for is recording audio from a firepod which uses /dev/raw1394 via jackd and there are no other FireWire devices connected, so security around this device is not really an issue. If I run as root, everything works as expected, but I have some folks that run the recorder that I don't want to have root access. However, I can't figure out which lines setup the perms I've tied this: /etc/udev/permissions.d/raw1394.rules:raw1394:root:root:0666 And I have this setup (default install) /lib/udev/rules.d/75-persistent-net-generator.rules:SUBSYSTEMS=="ieee1394", ENV{COMMENT}="Firewire device $attr{host_id})" /lib/udev/rules.d/75-cd-aliases-generator.rules:# the "path" of usb/ieee1394 devices changes frequently, use "id" /lib/udev/rules.d/75-cd-aliases-generator.rules:ACTION=="add", SUBSYSTEM=="block", SUBSYSTEMS=="usb|ieee1394", ENV{ID_CDROM}=="?*", ENV{GENERATED}!="?*", \ /lib/udev/rules.d/60-persistent-storage-tape.rules:KERNEL=="st*[0-9]|nst*[0-9]", ATTRS{ieee1394_id}=="?*", ENV{ID_SERIAL}="$attr{ieee1394_id}", ENV{ID_BUS}="ieee1394" /lib/udev/rules.d/50-udev-default.rules:# FireWire (deprecated dv1394 and video1394 drivers) /lib/udev/rules.d/50-udev-default.rules:KERNEL=="dv1394-[0-9]*", NAME="dv1394/%n", GROUP="video" /lib/udev/rules.d/50-udev-default.rules:KERNEL=="video1394-[0-9]*", NAME="video1394/%n", GROUP="video" /lib/udev/rules.d/60-persistent-storage.rules:KERNEL=="sd*[!0-9]|sr*", ATTRS{ieee1394_id}=="?*", SYMLINK+="disk/by-id/ieee1394-$attr{ieee1394_id}" /lib/udev/rules.d/60-persistent-storage.rules:KERNEL=="sd*[0-9]", ATTRS{ieee1394_id}=="?*", SYMLINK+="disk/by-id/ieee1394-$attr{ieee1394_id}-part%n" And I find these lines in /var/log/syslog Apr 30 09:11:30 record kernel: [ 3.284010] ieee1394: Node added: ID:BUS[0-00:1023] GUID[000a9200c7062266] Apr 30 09:11:30 record kernel: [ 3.284195] ieee1394: Host added: ID:BUS[0-01:1023] GUID[00d0035600a97b9f] Apr 30 09:11:30 record kernel: [ 18.372791] ieee1394: raw1394: /dev/raw1394 device initialized What I can't figure out, is which line actually creates that raw1394 device in the first place. How do you get /dev/raw1394 to have permissions 0666?

  • Xen dom0 reports incorrect amount of RAM with dom0_mem set

    - by xen_amnesiac
    I've done a fair bit of searching about this, but have found nothing that answers my question. I have a system with 6GB of RAM which acts as a Xen server. For reference, it runs Ubuntu 12.04. I've set the kernel parameter dom0_mem:512M,max:512M in /etc/default/grub as follows: GRUB_CMDLINE_XEN_DEFAULT="dom0_mem=min:512M,max:512M" I've tried variations of that, with the same result. My question is this: With the above set, the dom0 reports in all applications a RAM amount of 422M. cat /proc/meminfo gives the following: $ cat /proc/meminfo MemTotal: 432472 kB MemFree: 54144 kB Buffers: 17640 kB Cached: 220104 kB SwapCached: 30172 kB Active: 136500 kB Inactive: 167780 kB Active(anon): 6156 kB Inactive(anon): 60516 kB Active(file): 130344 kB Inactive(file): 107264 kB Unevictable: 52 kB Mlocked: 52 kB SwapTotal: 1794044 kB SwapFree: 1682012 kB Dirty: 0 kB Writeback: 0 kB AnonPages: 39572 kB Mapped: 8048 kB Shmem: 136 kB Slab: 44324 kB SReclaimable: 22012 kB SUnreclaim: 22312 kB KernelStack: 1280 kB PageTables: 3840 kB NFS_Unstable: 0 kB Bounce: 0 kB WritebackTmp: 0 kB CommitLimit: 2010280 kB Committed_AS: 329192 kB VmallocTotal: 34359738367 kB VmallocUsed: 313988 kB VmallocChunk: 34359417340 kB HardwareCorrupted: 0 kB AnonHugePages: 0 kB HugePages_Total: 0 HugePages_Free: 0 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 2048 kB DirectMap4k: 524696 kB DirectMap2M: 0 kB top, htop, free -m, and byobu's RAM monitor all report the same amount. At first I thought this was because of the onboard graphics borrowing some memory, but have now switched to a dedicated GPU and it persists. Is this normal behavior, or has something gone amiss? It's just about 100MB of RAM that's "gone", and I have no idea where it went. I understand that it's normal that not all RAM is available for allocation, but does the system really take an amount relatively high to the amount of RAM available?

  • Managing Many External Hosts Using EC2 and Route 53

    - by futureal
    Looking for a "best practice" answer to managing externally-addressable hosts using the combination of Amazon EC2 and Amazon Route 53, without using Elastic IPs for each host. In my scenario I will have 30+ hosts that need to be accessible from outside EC2, so directly using internal DNS will not work. In the past, I have addressed hosts by assigning an elastic IP to that host (let's say, 55.55.55.55) and then creating an associated A record. For example, let's say I want to create "ec2-corp01.mydomain.com" I might do: ec2-corp01.mydomain.com. A 55.55.55.55 300 Then on that EC2 instance, I would assign the Elastic IP of 55.55.55.55, and everything works fine. Of course, to make this work, I need to have one Elastic IP per instance, which is something I'd like to avoid if possible; I'd like the infrastructure to be more dynamic. So my thought is to try something like: Create a script that queries the internal EC2 tools to determine an instance's private hostname On instance boot, call that script to determine its hostname, and then using the command-line Route 53 interface to find and update that hostname to its current internal hostname Since the host will have a relatively low TTL (let's say 300 as above, or 5 minutes) it should take effect pretty quickly Is this a good idea? Is there a better or more widely accepted way to handle it? If it IS a good idea, what type of record should I be creating? A CNAME that points to the internal host, like ec2-55-55-55-55.compute-1.amazonaws.com? Is an A record better or worse? Thanks!
