• Monit send alert to nagios NSCA

  - by mYzk

  I want to monitor a web with monit check host function and if the site is down then alert it to nagios nsca so it sends the info to nagios and nagios marks it as status OK or host down for example. The problem is that how can I make the monit alert fuction send the info to nagios nsca. I am not sure that this will work, but what I came up with is: set alert exec 'echo -e "nagios nsca format" | /usr/local/nagios/bin/send_nsca -H serveraddress -c /usr/local/nagios/etc/send_nsca.cfg' Would this work and is it the best solution to work with or can it be done some other way?

• Limited access to Amazon S3 buckets

  - by Tomas Markauskas

  Is it possible to somehow limit the access to an Amazon S3 account. I don't really like the idea of distributing my secret access key to all of my applications, that want to access just a single bucket on my account. If someone gains access to one of the applications, I could loose all my data stored on S3. One way I was thinking to do it would be creating a second S3 account and give it access to just one bucket of the main account, but it's not really a great solution. Another nice thing for me would be to give the secondary account only write (but not modify/delete) and read access. That way I could upload backups or other files and be sure, that they won't get lost.

• How to call a program and exit from the shell (the caller) when program is active?

  - by Jack

  I want to run a program with GUI, by typing into konsole: foo args … and exit from the shell (that's the caller) when the program (foo) is active. How do I this? Is there a Linux/Unix built-in command/program to do it? I'm not a shell-man, really. I know that it's possible by writing a small program in C or C++ (any other programming language with small I/O interface on POSIX) programming language with the fork() and one-of exec*() function family. It may take some time; I'll do it only if there is no native solution. Sorry for my bad English; it's not my native language. Also, not sure on tags, please edit for me, if I'm wrong. If it matters, I'm using OpenSUSE 10.x.

• Communicate from PC in internet to remote GSM device

  - by Jakub Jezik

  I have several remote devices that use GSM modem and gather data. I need to communicate with those devices from a PC station located in a office using the dial up connection. Is there a way to do this WITHOUT an additional GSM modem connected to that PC? Is there some way to accomplish PC to remote GSM device communication using e.g. VoIP or similar technology? I want to avoid installing an additional GSM modem in the office and use some software solution instead.

• If your algorithm is correct, does it matter how long it took you to write it?

  - by John Isaacks

  I recently found out that Facebook had a programming challenge that if completed correctly you automatically get a phone interview. There is a sample challenge that asks you to write an algorithm that can solve a Tower of Hanoi type problem. Given a number of pegs and discs, an initial and final configuration; Your algorithm must determine the fewest steps possible to get to the final configuration and output the steps. This sample challenge gives you a 45 minute time limit but allows you to still test your code to see if it passes once your time limit expires. I did not know of any cute math solution that could solve it, and I didn't want to look for one since I think that would be cheating. So I tried to solve the challenge the best I could on my own. I was able to make an algorithm that worked and passed. However, it took me over 4 hours to make, much longer than the 45 minute requirement. Since it took me so much longer than the allotted time, I have not attempted the actual challenge. This got me wondering though, in reality does it really matter that it took me that long? I mean is this a sign that I will not be able to get a job at a place like this (not just Facebook, but Google, Fog Creek, etc.) and need to lower my aspirations, or does the fact that I actually passed on my first attempt even though it took too long be taken as good?

• How to handle sorting of complex objects?

  - by AedonEtLIRA

  How would one sort a list of objects that have more than one sortable element? Suppose you have a simple object Car and car is a defined as such: class Car { public String make; public String model; public int year; public String color; // ... No methods, just a structure / container } I designed a simple framework that would allow for multiple SortOptions to be provided to a Sorter that would then sort the list. interface ISorter<T> { List<T> sort(List<T> items); void addSortOption(ISortOption<T> option); ISortOption<T>[] getSortOptions(); void setSortOption(ISortOption<T> option); } interface ISortOption<T> { String getLabel(); int compare(T t1, T t2); } Example use class SimpleStringSorter extends MergeSorter<String> { { addSorter(new AlphaSorter()); } private static final class AlphaSorter implements ISortOption<String> { // ... implementation of alpha compare and get label } } The issue with this solution is that it is not easily expandable. If car was to ever receive a new field, say, currentOwner. I would need to add the field, then track down the sorter class file, implement a new sort option class then recompile the application for redistribution. Is there an easier more expandable/practical way to sort data like this?

• Insert escaped characters in seq command separator

  - by dhekir

  How do I insert a string containing escaped characters (\n, \t, etc) as separator for the seq command? The standard format includes a newline character: $ seq 3 1 2 3 But if I try to add something plus a newline, the backslash is escaped and a literal "\n" is used instead: $ seq -s "$\n" 3 1\n2\n3 The same happens using simple quotes, no quotes, or other escaped characters: $ seq -s "\t" 3 1\t2\t3 $ seq -s \t 3 1t2t3 This is not the standard behavior for commands such as echo, so I'm a bit confused here... Edit: Ideally, I'd like a somewhat portable solution (that works in tsch as well as bash, for instance), and without resorting to Perl or other languages.

• Mouse(s) double clicks instead of single click (its not the mouse)

  - by Iznogood

  I am aware of this very similar question: But I have tried with 3 different mouses and everyone of them exibit the same behavior. Simple enough, 1 out of 3 times I get a double click when single clicking). I searched the net a lot about this problem and have yet to find a solution. I have tried: 1- switch to another mouse 2- uninstall the mouse drivers + reboot 3- I do not have any special mouse drivers/software like intellisense and logitecs to uninstall. 4- verified that I was not in fact on some setting that says open files with single click. 5- everything is up to date including a antivirus 6- Installed fresh drivers from dell's website It is a dell vostro 260 computer running windows 7 pro 64. edit: added a 6th thing I tried. edit2: tried reinstalling every windows update I could find nothing Boss just said he'd buy me a logitech mouse hoping the drivers will fix my problems. Hopefuly!

• How do I make a backup of a live server?

  - by Jurily

  At my new job, I have a production server with the following qualities: Windows (XP I think), ancient hardware Absolutely vital database No backups whatsoever Everyone in the company has full admin rights, the passwords are stored in a .txt on the global share No installers, except for the OS The machine itself is sitting on a wooden shelf 5 feet above the ground against an external wall with frequent truck traffic on the other side; the shelf is already bent from the constant load Hasn't been rebooted in $DEITY knows how long, my predecessor wasn't even sure if it would survive it UPS is installed, but since everything is hooked up to it, it would last 10 minutes tops No spare parts or hardware budget How do I make a full backup with minimal impact on the server? I'm not sure how close it is to a total meltdown. For all I know, plugging in a USB stick could kill the company, and of course it will be all my fault, since "it was running fine before you touched it". The ideal solution would be a VM, so I have a test environment as well (separate of course).

• Encrypt shared files on AD Domain.

  - by Walter

  Can I encrypt shared files on windows server and allow only authenticated domain users have access to these files? The scenario as follows: I have a software development company, and I would like to protect my source code from being copied by my programmers. One problem is that some programmers use their own laptops to developing the company's software. In this scenario it's impossible to prevent developers from copying the source code for their laptops. In this case I thought about the following solution, but i don't know if it's possible to implement. The idea is to encrypt the source code and they are accessible (decrypted) only when developers are logged into the AD domain, ie if they are not logged into the AD domain, the source code would be encrypted be useless. How can be implemented this using EFS?

• Automating the insertion of credits in video files on Mac OS X

  - by Roberto Aloi

  I have a bunch of video files (mp4). I need to insert some title information at the beginning and some credits at the end. I'm currently using iMovie. Since the title could be extracted from the filename and the credits are always the same, I'm wondering how could I make all this process as automatic as possible. I was thinking about Automator, but I'm open to any other solution. iMovie is the preferred tool so far, but I could use anything else (as far as it doesn't require additional licensing/cost). Any idea?

• Behaviour of nginx as proxy

  - by HD

  I'm testing nginx with different configurations to replace an architecture working with squid + apache. I know that I can use nginx to manage static requests and load balancing but I'm interested in one particular solution that I don't understand clearly: I'm using 2 nginx servers (balanced) with the proxy_pass setting to pass all requests to an apache server. When one client makes a request to the site one of the nginx servers process it and send it to the apache server. Now, how this behaviour could be an improvement to my system?, it seems that all requests are passing through apache and I don't see benefit at all. What happens when 100 simultaneous connections pass through nginx? The 100 connections will be going to the apache server or is some kind of internal behaviour that allows an small impact into apache?

• Drag and drop to attachments feature only working intermittently in Outlook 2010

  - by Jared275

  I've been trying to troubleshoot a problem with my Outlook 2010 install where the ability to drag and drop an attachment into a new email will stop working from time to time. It seems to be fairly moonphase-y in that I can't seem to find a correlation in what causes it to stop working. Some searching online lead me to try running this command through the windows run dialogue: Regsvr32 ole32.dll, which apparently re-registers that particular dll as a command component in the registry. It didn't work, but I was curious as to why it was a suggested fix, and if there was something similar to try that would work, or another known solution.

• Migrating My GWB Blog Over To WordPress

  - by deadlydog

  Geeks With Blogs has been good to me, but there are too many tempting things about Word Press for me to stay with GWB.  Particularly their statistics features, and also I like that I can apply specific tags to my posts to make them easier to find in Google (and I never was able to get categories working on GWB). The one thing I don’t like about WordPress is I can’t seem to find a theme that stretches the Content area to take up the rest of the space on wide resolutions…..hopefully I’ll be able to overcome that obstacle soon though. For those who are curious as to how I actually moved all of my posts across, I ended up just using Live Writer to open my GWB posts, and then just changed it to publish to my WordPress blog.  This was fairly painless, but with my 27 posts it took probably about 2 hours of manual effort to do.  Most of the time WordPress was automatically able to copy the images over, but sometimes I had to save the pics from my GWB posts and then re-add them in Live Writer to my WordPress post.  I found another developers automated solution (in alpha mode), but opted to do it manually since I wanted to manually specify Categories and Tags on each post anyways.  The one thing I still have left to do is move the worthwhile comments across from the GWB posts to the new WordPress posts. The largest pain point was that with GWB I was using the Code Snippet Plugin for Live Writer for my source code snippets, and when they got transferred over to WordPress they looked horrible.  So I ended up finding a new Live Writer plugin called SyntaxHighlighter that looks even nicer on my posts If anybody knows of a nice WordPress theme that stretches the content area to fit the width of the screen, please let me know.  All of the themes I’ve found seem to have a max width set on them, so I end up with much wasted space on the left and right sides.  Since I post lots of code snippets, the more horizontal space the better! So if you want to continue to follow me, my blog's new home is now at https://deadlydog.wordpress.com

• How to backup a full Centos Server?

  - by benjisail

  Hi, I switched a few weeks ago from a dedicated server to a VPS. Now that everything is working well on the VPS I would like to shutdown the dedicated server and close my account with the hosting company. For peace of mind and in order to be more safe I would like to do a full backup of the server before stopping it. The best would be a backup that I could browse if I find that I need a something in the backup. What would be the best solution from command line? Thanks!!!

• Live streaming external FLV files

  - by fandelost

  I want to broadcast live video from a playlist created by me, but the actual video files (.flv's) are stored in some external file hosting which I can't admin, but it's currently allowing the use of flash players for playing its contents (progressively). Which is the best solution for this? Can I use my current web server (Debian w/Apache) or should I use some specific server software? I've read some names such as Red5 and Wowza but I can't tell if those are solutions to my actual problem or how should I use them. Also, costs should be as low as possible for this project.

• Rails: The Law of Demeter [duplicate]

  - by user2158382

  This question already has an answer here: Rails: Law of Demeter Confusion 4 answers I am reading a book called Rails AntiPatterns and they talk about using delegation to to avoid breaking the Law of Demeter. Here is their prime example: They believe that calling something like this in the controller is bad (and I agree) @street = @invoice.customer.address.street Their proposed solution is to do the following: class Customer has_one :address belongs_to :invoice def street address.street end end class Invoice has_one :customer def customer_street customer.street end end @street = @invoice.customer_street They are stating that since you only use one dot, you are not breaking the Law of Demeter here. I think this is incorrect, because you are still going through customer to go through address to get the invoice's street. I primarily got this idea from a blog post I read: http://www.dan-manges.com/blog/37 In the blog post the prime example is class Wallet attr_accessor :cash end class Customer has_one :wallet # attribute delegation def cash @wallet.cash end end class Paperboy def collect_money(customer, due_amount) if customer.cash < due_ammount raise InsufficientFundsError else customer.cash -= due_amount @collected_amount += due_amount end end end The blog post states that although there is only one dot customer.cash instead of customer.wallet.cash, this code still violates the Law of Demeter. Now in the Paperboy collect_money method, we don't have two dots, we just have one in "customer.cash". Has this delegation solved our problem? Not at all. If we look at the behavior, a paperboy is still reaching directly into a customer's wallet to get cash out. EDIT I completely understand and agree that this is still a violation and I need to create a method in Wallet called withdraw that handles the payment for me and that I should call that method inside the Customer class. What I don't get is that according to this process, my first example still violates the Law of Demeter because Invoice is still reaching directly into Customer to get the street. Can somebody help me clear the confusion. I have been searching for the past 2 days trying to let this topic sink in, but it is still confusing.

• Datacenter Backup Strategy

  - by EasyEcho

  What are common approaches to backup solutions in remote data centers? I am already familiar with general backup principals and have a very good backup strategy for our local data center but am having great difficulty extending it to a remote data center. We currently do a full backup on Friday, differential Mon - Thu, rotate offsite Friday morning ...rinse and repeat week after week. BTW, we use disks and have been very happy with this approach. We could buy a large storage server and backup everything to it, but this solution doesn't give you offsite. We could encrypt and upload to Amazon or some other online storage but that would take a large amount of time given the data and would be rather expensive paying for the bandwidth leaving the data center and receiving at amazon. We could drive to the data center every Friday and continue to rotate disks as we do now. But that just seems old fashion. What am I missing, are there better options?

• How would you measure the amount of atmospheric dust in a server room?

  - by Tom O'Connor

  We've been advised by our tape library vendor that one of the reasons we might be seeing lots of errors is if our server room is particularly dusty. It doesn't look dusty, but that's not to say it's not there. We've got an environment sensor cluster which measures Temperature, Airflow and Relative Humidity. I should probably point out that the low-hanging fruit solution I came up with is to use Sellotape (scotch tape) in a loop, one side stuck to the server cabinet, the other side free-hanging. I've also put a couple of other tape loops by the exit and intake fans of the hardware (not blocking airflow, naturally). How can we (electronically, ideally) measure dust levels?

• How can I include my derived class type name in the serialized JSON?

  - by ChrisD

  Sometimes working with the js Serializer is easy, sometimes its not.   When I attempt to serialize an object that is derived from a base, the serializer decided whether or not to include the type name. When its present, the type name is represented by a ___type attribute in the serialized json like this: {"d":{"__type":"Commerce.Integration.Surfaces.OrderCreationRequest","RepId":0}} The missing type name is a problem if I intend to ship the object back into a web method that needs to deserialize the object.   Without the Type name, serialization will fail and result in a ugly web exception. The solution, which feels more like a work-around, is to explicitly tell the serializer to ALWAYS generate the type name for each derived type.  You make this declaration by adding a [GenerateScriptType())] attribute for each derived type to the top of the web page declaration.   For example, assuming I had 3 derivations of OrderCreationRequest; PersonalOrderCreationRequest, CompanyOrderCreationRequest, InternalOrderCreationRequestion, the code-behind for my web page would be decorated as follows: [GenerateScriptType(typeof(PersonalOrderCreationRequest))] [GenerateScriptType(typeof(CompanyOrderCreationRequest))] [GenerateScriptType(typeof(InternalOrderCreationRequest))] public partial class OrderMethods : Page { ... } With the type names generated in the serialized JSON, the serializer can successfully deserialize instances of any of these types passed into a web method. Hope this helps you as much as it did me.

• How to "restart/repair" an USB port?

  - by Click Ok

  My laptop have 2 usb ports, but one is broken, so I use an USB hub in the another good USB port. In that USB hub, I use a mouse and keyboard. Suddenly, that USB port doesn't detects the mouse and keyboard (even with the light of the hub is on), and the only solution that I found is restarting the laptop. But just some minutes and the keyboard and mouse goes undetected again... So, I wonder if there is some method/software/etc to "restart/repair" the USB port without restart the PC. Thanks for all!

• How do I disable spell checking in IE 11 (Win 8.1)?

  My issue is similar to the one mentioned here: Disable spell checking in Internet Explorer 10 (Windows 8) I am using Windows 8.1 Pro 64-bit What I've tried already: Deactivating the spelling options: From the following, borrowed screenshot from the old Windows 8 (my interface is German, therefore I couldn't create one myself), I have turned both options off and restarted IE. It's still "correcting" my texts. Searching for 'spelling correction' addons: The indicated option in the following borrowed screensnot does not exist on my PC. Is there any way of disabling it? I prefer a canonical solution if one is available. If not, I am also interested in registry hacks or other solutions.

• What's the strengths and weaknesses of existing configuration management systems?

  - by Daniel C. Sobral

  I was looking up here for some comparisons between CFEngine, Puppet, Chef, bcfg2, AutomateIt and whatever other configuration management systems might be out there, and was very surprised I could find very little here on Server Fault. For instance, I only knew of the first three links above -- the other two I found on a related google search. So, I'm not interested in what people think is the best one, or which they like. I'd like to know the following: Configuration Management System's name. Why it was created (as opposed to using an existing solution). Relative strengths. Relative weaknesses. License. Link to project and examples.

• Posting videos to a website... with a dynamically updating interface

  - by Johnny W

  I'm currently putting together a website for my Luddite friend. He needs a blog, photos and videos... all easily updateable by him. WordPress and Blogger both have brilliant functionality to allow you to host your own blog on your own domain, but what about photos and videos? Does YouTube or Google videos or Vimeo or MSN Video or anyone offer the ability to easily insert a video navigation interface onto your own site? (Something similar to YouTube's "Channel" pages, except on your own domain?) Same goes for photos. I'm pretty sure FlickR doesn't allow you to easily upload and manage photos for viewing on your own domain. Does anyone else? My friend doesn't want to be editing any HTML and I don't want to be creating a complicated system to handle tons of different videos. There must a user-friendly solution in this day and age? Thanks for any help!

• PGP - MailCloak/Gpg4Win/etc

  - by ericl42

  Hello, I have used Gpg4Win in the past along with FireGPG to have encryption on my emails. I am needing to roll this out to quite a few more people and was wondering if anyone else had some products they preferred better. The criteria I need is free and as user friendly as possible. I looked at MailCloak but I have had some issues with it on 1 of the 2 computers I've been testing on. It seems like it might work pretty well as a overall solution but on my computer I keep getting "Identity cannot be created." and not sure whats going on with that. Thanks for the info.
