  • Nagios not accepting regex in command

    - by Creshal
    I have this command defined: define command{ command_name check_http_sane command_line $USER1$/check_http -H $HOSTNAME$ -r "HTTP/1.1 (200|301|302|303|304|307|401|418|426)" } When I run it manually on command line, it works fine, but nagios (2.6) reports a "pattern not found" error. Do I need to escape something? Edit: As stated below, I solved it by replacing check_http with my own script which works (good enough for our use case, anyway). Script: http://pastebin.com/hNmz6Wa1

  • Pivot Table Does Not Refresh Source

    - by AME
    Typically, when selecting a data source for a pivot table in Excel 2013, it is possible to refresh the table by selecting "refresh table" or "refresh all". This triggers an update in the Pivot Table based on changes in the underlying data source. However, I am running into a case where this functionality does not prompt a refresh of the pivot table. What might be causing the pivot table in Excel 2013 to remain static when selecting "refresh data"?

  • Extracting Windows executable installers on Mac Os X?

    - by James McMahon
    Is there a program or a script out there to extract the contents of a Windows installer under Mac Os X? Under Windows there is the Universal Extractor, I am looking like something like that for Mac. I don't know if there is a universal solution to this problem or if I would need a extractor specific to the type of installer. In my case I am actually trying to get the installer from Gog.com to extract so I can use them with Boxer.

  • Do glue records in non-circular dns-lookups speed up domain resolution or not?

    - by Joe Hopfgartner
    Doing a lookup for my domain on http://www.intodns.com/ I noticed theese two messages: In Parent section: DNS Parent sent Glue The parent nameserver g.gtld-servers.net is not sending out GLUE for every nameservers listed, meaning he is sending out your nameservers host names without sending the A records of those nameservers. It's ok but you have to know that this will require an extra A lookup that can delay a little the connections to your site. This happens a lot if you have nameservers on different TLD (domain.com for example with nameserver ns.domain.org.) and in NS section: Glue for NS records INFO: GLUE was not sent when I asked your nameservers for your NS records.This is ok but you should know that in this case an extra A record lookup is required in order to get the IPs of your NS records. The nameservers without glue are: 109.230.225.96 84.201.40.52 You can fix this for example by adding A records to your nameservers for the zones listed above. I do perfectly understand that the primary objective of glue records is to resolve circular dependencies. The classic use case: my domain is example.com and I want to have the nameserver ns1.example.com. This will never work because i cannot know the ip of ns1.example.com if I don't fetch example.com and in order to do that I need to fetch it from ns1.example.com. To resolve this deadlock I add a glue record to ns1.example.com containing the ip adress of the nameserver, so this can work out. So this problem does not occour if the nameservers are in a different TLD than the domain i want to look up. But however to fetch the zone information from the nameservers I need to know their ip adress right? And in order to know that i need to fetch the zone the nameservers are in from their respective nameservers, right? (or rather my ISP needs to do that in the background) So an extra lookup that takes time? If I now have glue records, I know the IP adress right away without the need to look it up - so this should speed up the resolution of my domain, shouldnt it? However my DNS zone provider (tecserver.at) replied that this would make no sense because "we are not running ns1.ourdomain.com an ns1.ourdomain.com as authorative NS for ourdomain.com. This would be the only sense for glue records. Tecserver has a glue record because the NS for tecserver.at are ns1.tecserver.at and ns2.tecserver.at. Therefore a glue record is needed for resolution.

  • Use quicksilver to tell itunes to stop

    - by user10826
    Hi, I am starting to use Quicksilver in Mac OS X. At the moment I just know how to "call it" (CMD+I in my case) and open an app. I wonder how could I do, once itunes is running, just to tell to stop playing a song, using QS, and if not, someother workaround, just using Keyboard, in the simplest possible wy. Thanks

  • What's a good asterisk hosting provider?

    - by MCS
    Does anyone know of a good hosting provider for asterisk? I came across lylix but don't know if they're any good. Of course I could always install asterisk myself on a godaddy vps, but figure it will be easier (and in the case of lylix, cheaper) to have it done for me.

  • Can you rely on Nginx as your only webserver for php/mysql

    - by Saif Bechan
    Can you rely on Nginx to be your only webserver. I know in terms of performance it works well, but how does it do in terms of security. I know Apache is stable and has ModSecurity. This is not the case for Nginx. I am going to use Nginx as only webserver, and only for dynamic content. All my static content is delivered by a CDN.

  • Migrating SBS 2003 to 2011, and hangs when migrating Public Folders

    - by Daniel P
    I've been following the migration guide at http://www.it-book.co.uk/1651/migration-from-sbs-2003-to-sbs-2011-3. The option "Migrate Exchange mailbox and settings" links me to http://technet.microsoft.com/en-us/library/gg563803.aspx When I get to the stage of right-clicking "Move All Replicas", it instantly hangs. I can't see anything specifically in the event viewer at the time this happens. Is this a case of waiting, or is there something more going on here?

  • Reproducible file corruption for files on windows share

    - by bbuser
    We have about 40 file servers in our intranet to distribute software packages. The servers have names like example01, example02 etc. Every name resolves to a single IP-address (A-record) and the IP resolves back to that name (PTR) for every single server. The thing is, that for a certain file (mypackage.cab) I get different results depending on whether I use: \\192.0.2.01\fs\pkg\X12345678 or \\example01.foo\fs\pkg\X12345678 While in one case the file is correct in the other case the file has exactly the right size, but it is all zeros. For a certain combination of client and server I can reproduce this reliably. It doesn´t matter if I download in Windows Explorer, via robocopy or even from Linux with smbclient. It´s always the same, one file corrupt, the other ok. It happens only for certain combinations of clients and servers, not others. For example: client01 example01.foo -> OK (192.0.2.01 is also OK) client01 example02.foo -> broken (but 192.0.2.02 is OK) client02 example01.foo -> broken (but 192.0.2.01 is OK) client02 example02.foo -> OK (192.0.2.02 is also OK) client03 example06.foo -> OK (but 192.0.2.06 is broken) client03 example07.foo -> OK (192.0.2.07 is also OK) etc... In some cases I get the broken file when I use the IP address in other cases when I use the name. For every client the majority of servers is Ok, but from every client I tested I have at least 4 cases of broken files. All this happens only for mypackage.cab (about 5k in size), it never happened for any of the other files in the same directory. Confused? Certainly I am. Any idea what can cause this or any idea what to try to figure it out is welcome. Clients are Windows XP. Servers are NetApp filers I don´t have access to. I can (and will) contact the filer team again, but first I have to have an idea what is going on.

  • ln -s not working under /mnt/

    - by Yaniv
    Hi all I'm following this tutorial to set up a LAMP stack on EC2 with persistent storage on EBS. It all works well when doing it step by step. But in case you want to mount your EBS under /mnt instead of under the root directory the ln -s commands won't work! I tried: ln -s /mnt/ebs1/httpd /etc and: ln -s /mnt/ebs1/httpd /etc/httpd Is there a difference when linking to a file on a device that is mounted under /mnt? (working on fedora core 8)

  • Retrieving a virtual box vdh that has been deleted from within Virtual box itself

    - by WillNZ
    I had a MS Virtual machine that I imported to virtual box to see how it worked. I decided that in this case MS Virtual machine worked just as good so removed the virtual machine from Virtual Box. In the process I accidently removed/deleted the vhd file that MS Virtual machine uses. Can I get this back from somewhere within virtual box or the recycle bin or do I have to use a undelete utlilty?

  • Subtitle program for DVD on Mac

    - by nocturnal
    I like the looks of Belle Nuit Subtitler, even though the price is a bit high. Does anyone know any other program like it that can add subtitles to a video stream while watching the stream itself? I want this to translate DVD's, in case that matters. I'm willing to purchase it if the program can deliver what i need but would like to see alternatives to Belle Nuit.

  • dreamweaver disable "language for non unicode programs" detection

    - by YuriKolovsky
    Dreamweaver CS4 auto-detects the language for non unicode programs in windows, in my case it is russian, and conviniently sets the default encoding to be western european instead of the much preferred utf-8, it also changes several bits of text in DW into russian. how do i disable this detection and maintain Dreamweaver in full english? (without having to change the language for non-unicode programs in windows)

  • Are Time Machine backups secure?

    - by Leandro Ardissone
    I have my Time Machine backups on an external disk (WD My Passport with no hardware encryption) and I'm worried if the data stored on the disk is safe in case somebody steals it and connect it to any Mac/PC. Does any Mac can browse the Time Machine backups? Or are they encrypted in any way? If no, is there a way to improve security of the backups, should I buy a hardware encryption based HD? Thanks.

  • Anti-glare filter for touch enabled Netbook?

    - by chris
    Is it possible to put an anti-glare filter on a touch enabled Netbook without disabling the touch functionality? If yes, would it also be possible to remove the filter without damaging the screen? In my case it's an Acer 1420p (the PDC edition). It's a good machine but unfortunately you can also use it as a mirror.

  • Use lineout on Mac for audio processing

    - by eltufto
    Does anyone know of a way to set the linein on a Mac to route from the lineout? I want to essentially work with the music played on my Mac. An alternative solution I suppose would be to set the Linein as the output from iTunes/other music player. For context: My specific use-case is audio processing in Processing with the minim library, calling getLineIn. Trying to create some visuals that respond to the music being played.

  • HP DX5150, MS-7050 v. 1.3 Motherboard front panel pin connectors

    - by Daniel
    I recently purchased and installed a MS-7050 v. 1.3 motherboard into a regular non-HP case and thus the front panel connectors are different than the original OEM connectors which are all bundled together. The HP support website does not have this information available and someone from HP indicated in response to a support forum question that this information is not available. What is the motherboard pin schematic for the front panel i/o connectors (power, reset, hdd led, and power led)?

  • Handling site not found and page not found with dynamic mass virtual hosting

    - by Rick Moynihan
    I have recently setup mass virtual hosting in Apache so that all we need to do is create a directory to create a new vhost. We're then also using wildcard DNS to map all subdomains to the server running our Apache instance. This works excellently, however I'm now having trouble configuring it to fail-over to an appropriate default/error-page when the vhost directory does not exist. The problem appears to be conflated between by my desire to handle the two error conditions: vhost not found i.e. there was no directory found matching the host supplied in the HTTP host header. I'd like this to display an appropriate site not found error page. The 404 page not found condition of the vhost. Additionally I have a specialised "api" vhost in its own vhost block. I've tried a number of variations and none seem to exhibit the behaviour I want. Here's what I'm working with right now: NameVirtualHost *:80 <VirtualHost *:80> DocumentRoot /var/www/site-not-found ServerName sitenotfound.mydomain.org ErrorDocument 500 /500.html ErrorDocument 404 /500.html </VirtualHost> <VirtualHost *:80> ServerName api.mydomain.org DocumentRoot /var/www/vhosts/api.mydomain.org/current # other directives, e.g. setting up passenger/rails etc... </VirtualHost> <VirtualHost *:80> # get the server name from the Host: header UseCanonicalName Off VirtualDocumentRoot /var/www/vhosts/%0/current # other directives ... e.g proxy passing to api etc... ErrorDocument 404 /404.html </VirtualHost> My understanding is that the first vhost block is used as the default, so I have this here as my catch all site. Next I have my API vhost, and then finally my mass vhost block. So for a domain that doesn't match the first two ServerName's and has no corresponding directory in /var/www/vhosts/ I'd expect it to fall-over to the first vhost, however with this setup, all domains resolve to my default site-not-found. Why is this? By putting the mass-vhost block first, I can get the mass-vhosts to resolve properly, but not my site-not-found vhost... and in this case I can't seem to find a way to distinguish between a page-level 404 in the vhost, and the case where the VirtualDocumentRoot fails to find a vhost directory (this appears to use the 404 also). Any help out of this bind is much appreciated!

  • How might I stop BACKSCATTER using Qmail?

    - by alecb
    New to ServerFault , please pardon if my details are too much Linux box acting as Virtual Host for domain hosting. Runs CentOs. Runs Parallels Plesk 9.x Regardless of the following, the SPAM keeps flowing in at 1-3 / second. An explanation of the problem... "xinetd service listens for SMTP connections and forwards to qmail-smtpd. The qmail service only process the queue, but does not control messages coming into the queue...that's why stopping it has no effect. If you stop xinetd AND qmail, then kill any open qmail-smtpd processes, all mail flow comes to a stop SOMETIMES Problem is, qmail-smtpd is not smart enough to check for valid mailboxes on the localhost before accepting the mail. So, it accepts bad mail with a forged replyto address which gets processed in the queue by qmail. Qmail cannot deliver locally and bounces to the forged replyto address." We believe the fix is to patch the qmail-smtpd process to give it the intelligence to check for the existence of local mailboxes BEFORE accepting the message. The problem is when we try to compile the chkuser patch we run into failures due to Plesk Control Panel." Is anyone aware of something we could do differently or better?" Other things that have NOT worked thus far: -Turning off any and all mail processes (to check as an indicator that an individual account has been compromised. This has been verified as NOT the case.) -Turning off mail AND http server processes (in the case of a compromised formmail) -Running EXIM in lieu of Qmail( easy/quick install but xinetd forces exim to close and restarts qmail on its own) -Turned on SPF protection via Plesk GUI. Does not help. -Turned on Greylisting via Plesk GUI. Does not help. -Disabled Bounce notifications via command line That which MIGHT work but have complications: -Use POSTFIX instead of QMAIL (No knowledge of POSTIFX and don't want to bother with it unless anyone knows it has potential to handle backscatter WELL before investing time) -As mentioned above, compiling a chkusr patch, we believe will STOP this problem, along with qmail (because of plesk in the mix, the comile fails every time and Parallels Plesk support is unresponsive unless I cough up MONEY) If I don't clear out the SPAM from the outgoing mail queue nightly, then it clogs up with millions of SPAMs and will bring down the OUTGOING email services. Any and all help welcome and appreciated!
