  • Iptables mark incoming packet - vpn routing

    - by Tom
    I have connected my home to my workplace for out of house backup reasons through openvpn. The connection is working nicely. At work I have 5 fixed IP addresses. Now I would like to assign one of these IP addresses to be forwarded to my home machine. I have confirmed packet arrival at my home machine with tcpdump. The problem is that my default route at home is NOT the tun0 (naturally), but eth0 to my own ISP. So I created a separate routing table to route my tun0 packets back to where they belong, but do not how to mark the incoming packet which arrive through tun0 with iptables, so I can drive them back. I do not want any port restrictions, but only what comes from tun0 should leave through tun0 thanks tom

  • Sound in Ubuntu 12.10 on Chromebook

    - by Paul Mennega
    I've got an HP Chromebook 14 that I've rooted and installed Ubuntu via Crouton (upgraded to 12.10) and most things are working nicely. One issue that I am having trouble solving relates to sound. I've got sound output that I can control via the individual app (e.g. Youtube), but when trying to control the volume via the built-in xfce4-mixer, I get the following error: GStreamer was unable to detect any sound devices. Some sound system specific GStreamer packages may be missing. It may also be a permissions problem. Opening a terminal, I can run the alsamixer and control the volume levels. It is reporting back that the card is CRAS. I'd love to be able to do it from XFCE and the built-in mixer. I've tried re-installing the GStreamer packages, but no luck. It seems like I am close but not sure where to go from here. On a maybe unrelated note, plugging headphones into the headphone jack in Ubuntu also does not stop the sound from coming from the speakers and nothing comes through the headphones. Switching back to ChromeOs, everything works as expected, so I think that it's a driver issue.

  • How to stop OS X from switching input method (keyboard layout) automatically?

    - by adolf garlic
    After using the wireless keyboard that comes with the iMac, I have switched to a MS Ergo Natural 4000 one. Surprisingly I had to install extra software as OS X could not work out which keyboard I had. After which I went into sys prefs and set the main input method to be "British - Microsoft" first and "Swiss German" second (what the wireless keyboard is), on the "input sources" tab: However... OS X keeps resetting my input method back to Swiss German which is driving me bananas. I have the flag thingy top right so I can see when this changes. N.B. I have "input source options" set to "use the same one in all documents" which I am assuming means keep the language the same for anything running. It also flips back on the login page. Does anyone know how to fix this?

  • Making simple forms in web applications

    - by levalex
    How do you work with forms in your web applications? I am not talking about RESTful applications, I don't want to build heavy front-end using frameworks like Backbone. For example, I need to add "contact us" form. I need to check data which was filled by user and tell him that his data was sent. Requirements: I want to use AJAX. I want to validate form on back-end side and don't want to duplicate the same code on front-end side. I have my own solution, but it doesn't satisfy me. I make an AJAX request with serialized data on form submit and get response. The next is checking "Content-type" header. html - It means that errors with filling form are exists and response html is form with error labels. - I will replace my form with response html. json and response.error_code == 0 - It means that form was successfully submited. - I will show user notification about success. json and response.error_code != 0 - Something was broken on back-end (like connection with database). other - I display the following message : We have been notified and have started to work with that problem. Please, try it later. The problem of that way is that I can't use it with forms that upload file. What is your practise? What libraries and principles do you use?

  • f12 and ctrl + f5 not working correctly

    - by ComatoseDuck
    When I came back to my work computer after being away for a week I found out when I try to clear the cache and refresh the page via ctrl + f5 (or just f5) I get the prompt "Type the Internet address of a document, and Internet Explorer will open it for you" with a drop down list in IE. When I try f5 in Chrome and FF it opens the "Open file" dialog box. When I try to f12 for Dev tools in IE, Chrome & FF it opens up the print dialog box. Why is this happening and what can I do to revert it back to the way it was?

  • Changing DNS - Forgot to change MX records for one month - Is there a way to retrieve emails that we

    - by Chris Altman
    We have our own domain. Our email is hosted by Google Apps. We switched web servers and name servers to a new provider. In the switch, I forgot to move the MX record. When people tried to send emails to our domain, there was no bounce back. We fixed the MX record and now receive email. Is there anyway to retrieve the emails that were sent in the month when there was no MX record? I doubt it because there was no MX record on our name server. Where would the emails have gone since they did not bounce back?

  • Browser language detection & content ranking for new language on the same site.

    - by Arnaud
    I've been reading a lot about it but it's still really hard to make up my mind. My understand is that if your website provide a link to the other language, this should not be an issue for google as long as your links are clear and clean, google will be able to make his way through it. The website was orginaly in french and I added the english version and I'm just worry that english speaker will just leave if the site is not in the correct language, for the home page I just wanted to get the value from the browser and redirect it to /fr/ or /en/ for the first page. (using php this will be very easy) Could you guys have a look at it and tell me what you think about it http://tinyurl.com/bpc5bn9 I don't want to get it wrong and lost my ranking with google. Also the website has good rank on the french side and the english has been online for 2 weeks and only get few visit a day, is that because all the back link refer to /fr/ and google is cleaver enough to decide that they are 2 differantes website and the back link will have to point to /en/ to increase the ranking value? Or will take few more weeks for the website to grow? Thanks for your hep

  • GNOME changes to KDE on Maverick

    - by Pit
    Hi, I recently made a clean/fresh install of Ubuntu 10.10 an experienced the problem that the theme changes from Gnome to KDE and back randomly and partly. Sometimes after starting my computer I will have a KDE theme. If I then open the Appearance Preferences ( System - Preferences - Appearance ) some applications and the main-menu as well as menu of applications (only upper two centimetres of a application window) will change back to Gnome only by opening it, not changing anything nor saving. I did not choose KDE at any time, nor did I do any changes to the appearance prior to the first occurrence of this bug. On a second computer I updated from 10.04 to 10.10 and experienced the same bug. On this computer I did however change the layout of the minimize;maximise;close buttons by following How do I move the Window buttons from left to right?. But I don't see how this could provoke the bug, especially as it occurs on a second computer. Will doing updates I saw that there a quite a lot of KDE packages being downloaded. Do I even need those if I don't want to use KDE?

  • How to open recovered files in word?

    - by GiH
    My computer restarted while I was asleep because of system updates (need to turn that off), and when I opened up Word the first time after it restarted, it gave me a pane on the left hand side that showed me all the documents I had opened. I chose one of the documents but I want to open them all, how can I bring that pane back? Update: I forgot to mention I'm on Word 2007. I've found that if you go to C:\Users*YOURUSER*\AppData\Roaming\Microsoft\Word you can see the autorecovery files. Mine are still in there, but I don't want to touch them, I'd rather bring back that pane and do it right just in case they disappear as soon as I double click haha...

  • Automated Acceptance tests under specific contraints

    - by HH_
    This is a follow up to my previous question, which was a bit general, so I'll be asking for a more precise situation. I want to automate acceptance testing on a web application. Briefly, this application allows the user to create contracts for subscribers with the two constraints: You cannot create more than one contract for a subscriber. Once a contract is created, it cannot be deleted (from the UI) Let's say TestCreate is a test case with tests for the normal creation of a contract. The constraints have introduced complexities to the testing process, mainly dependencies between test cases and test executions. Before we run TestCreate we need to make sure that the application is in a suitable state (the subscriber has no contract) If we run TestCreate twice, the second run will fail since the state of the application will have changed. So we need to revert back to the initial state (i.e. delete the contract), which is impossible to do from the UI. More generally, after each test case we should guarantee that the state is reverted back. And since, in this case, it is impossible to do it from the UI, how do you handle this? Possible solution: I thought about doing a backup of the database in the state that I desire, and after each test case, run a script which deletes the db and restores the backup. However, I find that to be too heavy to do for each single test case. In addition, what if some information are stored in files? or in multiple or unaccessible databases? My question: In this situation, what would an experienced tester do to write automated and maintanable tests. Thank you. More info: I'm trying to integrate tests into a BDD framework, which I find to be a neat solution for test documentation and communication, but it does not solve this particular problem (it even makes it harder)

  • What's the best practice to do SOA exception handling?

    - by sun1991
    Here's some interesting debate going on between me and my colleague when coming to handle SOA exceptions: On one side, I support what Juval Lowy said in Programming WCF Services 3rd Edition: As stated at the beginning of this chapter, it is a common illusion that clients care about errors or have anything meaningful to do when they occur. Any attempt to bake such capabilities into the client creates an inordinate degree of coupling between the client and the object, raising serious design questions. How could the client possibly know more about the error than the service, unless it is tightly coupled to it? What if the error originated several layers below the service—should the client be coupled to those lowlevel layers? Should the client try the call again? How often and how frequently? Should the client inform the user of the error? Is there a user? By having all service exceptions be indistinguishable from one another, WCF decouples the client from the service. The less the client knows about what happened on the service side, the more decoupled the interaction will be. On the other side, here's what my colleague suggest: I believe it’s simply incorrect, as it does not align with best practices in building a service oriented architecture and it ignores the general idea that there are problems that users are able to recover from, such as not keying a value correctly. If we considered only systems exceptions, perhaps this idea holds, but systems exceptions are only part of the exception domain. User recoverable exceptions are the other part of the domain and are likely to happen on a regular basis. I believe the correct way to build a service oriented architecture is to map user recoverable situations to checked exceptions, then to marshall each checked exception back to the client as a unique exception that client application programmers are able to handle appropriately. Marshall all runtime exceptions back to the client as a system exception, along with the stack trace so that it is easy to troubleshoot the root cause. I'd like to know what you think about this? Thank you.

  • MVC + 3 tier; where ViewModels come into play?

    - by mikhairu
    I'm designing a 3-tiered application using ASP.NET MVC 4. I used the following resources as a reference. CodeProject: MVC + N-tier + Entity Framework Separating data access in ASP.NET MVC I have the following desingn so far. Presentation Layer (PL) (main MVC project, where M of MVC was moved to Data Access Layer): MyProjectName.Main Views/ Controllers/ ... Business Logic Layer (BLL): MyProjectName.BLL ViewModels/ ProjectServices/ ... Data Access Layer (DAL): MyProjectName.DAL Models/ Repositories.EF/ Repositories.Dapper/ ... Now, PL references BLL and BLL references DAL. This way lower layer does not depend on the one above it. In this design PL invokes a service of the BLL. PL can pass a View Model to BLL and BLL can pass a View Model back to PL. Also, BLL invokes DAL layer and DAL layer can return a Model back to BLL. BLL can in turn build a View Model and return it to PL. Up to now this pattern was working for me. However, I've ran into a problem where some of my ViewModels require joins on several entities. In the plain MVC approach, in the controller I used a LINQ query to do joins and then select new MyViewModel(){ ... }. But now, in the DAL I do not have access to where ViewModels are defined (in the BLL). This means I cannot do joins in DAL and return it to BLL. It seems I have to do separate queries in DAL (instead of joins in one query) and BLL would then use the result of these to build a ViewModel. This is very inconvenient, but I don't think I should be exposing DAL to ViewModels. Any ideas how I can solve this dilemma? Thanks.

  • Need disc image help pronto!

    - by data
    I recently got a job as a junior network administrator. Last week the senior admins did their yearly reinstall of server 2003, exchange, drivers etc on the main server. I've been asked to back up the disc so that next year they can just copy over the pre-made image. What tools can i use to achieve both the creation of the entire servers HDD image and loading it back on (id like to test it in the sandbox.) To impress them, a program that is free is preferable. And maybe a tool that can do it all from booting the program off of a USB drive.

  • Can I import contacts from an Exchange 2003 EDB file for a single user?

    - by Drarok
    We have recently had to reinstall a very unhappy Exchange 2003 server for a client, and whilst rebuilding their server we moved them onto a temporary one. During the course of all this, ExMerge was used due to Windows being so broken that none of the backup software could run. As a number of the user mailboxes were way over 2GB, we had to do date ranges of a few months at a time to avoid ExMerge's 2GB limit. We went back as far as 2006, as the files produced by ExMerge seemed empty that far back. Unfortunately, one of the users has reported that around 2 3rds of their contacts are missing, and that pre-2006 sounds about right for the missing items. Is there any way I can mount the old EDB file into Exchange, or otherwise read their contacts into a usable format? The server is running Windows Server 2003 SBS R2 (SP2), and Exchance 2003 (SP2, I think).

  • PSU failing or Mainboard failing?

    - by Andrei Rinea
    I am having some troubles lately powering on my desktop workstation. While starting up the PC after being off for hours (usually at least 8 hours) it randomly fails to do so. What happens is that : I press the power button; nothing happens I can hear a moderate buzzing noise at the back of the PC (near the PSU); but I can't say for sure that it's not from the mainboard. If I insist pressing the power button a few times in 1-2 minutes it'll start Another route would be that instead of (3) I will plug off the power cable from the PSU and wait for 30 seconds. Then I will press the power on and keep it for 30-60 seconds (I had some success at notebooks with a similar approach). Then I will plug back the cable in the PSU, press only once the power button and it will start normally. Also while running normally I keep hearing some low buzzing which seems to be fan-RPM-related (i.e. when processing images or doing CPU intensive work). What should I look into? UPDATE It's getting worse. It took more than 10 retries today and almost 20 minutes to start the computer. I tried the paperclip trick and the PSU behaves perfectly. I managed to start the computer like so : I pressed the on-button a few times and then left the PC in a pre-startup state (the fans were working the buzzing noise was strong and I went to eat. I thought I won't lit the house on fire so fast and without smelling. Back, after 10-15 min the computer booted up! Discussed with a fellow at Intel and he told me the capacitors on the mainboard are probably a bit shot. If they are shot, he said, it should start up warm perfectly. So I did restart it, warm, a few times (5 sec cooldown and then 40 sec cooldown and it started up perfectly). I can either replace the capacitors on the mainboard (doesn't sound worth it or replace the mainboard (this one sucks too :)) ) FINAL INFO : It was the PSU after all. Although it was powering the IDEs and SATAs the Mainboard power module was failing. I bought another mainboard just to find out that this wasn't the cause. Now I'll have to return it somehow. The spare PSU is now in the computer and doing well.. Although larger (500W), it's like a plane taking off.. I need a better one.

  • How do I backup my customer's data?

    - by marcamillion
    If you run a SaaS app, or work on one, I would love to hear from you. Where the safety and security of your customer's data is paramount, how do you secure it and back it up? I would love to know your main host (e.g. Heroku, Engine Yard, Rackspace, MediaTemple, etc.) and who you use for your backup. Be as detailed as possible - e.g. a quick overview of your service and the data you store (images for instance), what happens with the images when the user uploads them (e.g. they go to your Linode VPS, and posted to the site for them to see - then they are automatically sent to AWS or wherever, then once a week they are backed up to tape by the managed hosting provider, and you also back them up to your house/office). If you could also give some idea as to what the unit cost (per GB/per user/per month) of storage is - on average, I would really appreciate that. Getting ready to launch my app, and I would love to get some more perspective on the nitty gritty details involved. Thanks!

  • IBM x3620 Server takes a long time to boot past UEFI to OS

    - by Joel Coel
    I have a pair of IBM System x3620 servers. These servers do fine once they finally reach the point where the operating system takes over, but it takes them forever to get past the new-fangled UEFI boot system... a good five minutes or so; maybe longer. I haven't timed it, but it's the kind of thing where you go get a cup of coffee while you wait and it's still going when you come back. Normally the only time I shut these down is for a monthly maintenance cycle (usually just windows updates), and so it's not a big deal. But in the case where I might have an outage I'd sure like to get that 5 minutes back. Is there anything I can do to tell them to just go ahead and boot already?

  • Is there an open source clone of a game in the Total War Series?

    - by sinekonata
    I loved Shogun:Total War gameplay and then later on spent weeks re-enacting historical wars and battles with Europa Barbarorum. It's a mod for Rome:TW that focuses on historical accuracy in the peoples, units, sounds, visuals, everything from macro mechanics to actual battles (e.g. a lot more missiles). Since that time I kind of turned my back on Windows cause it sucks and use Linux cause Mac sucks even worse. So as I miss that game (Eur. Barb.) and consider it the most realistic RTS to date, I'd like to know if there are any free and open source alternatives to it because ever since I'm under linux, I became addicted to FOSS so I also turned my back on paying (even kickstarters) for closed source, pay to play games. I have found a clone/alternative for everyone of the best games like Minecraft, CSS, Natural Selection, TA/SupCom etc... It's kind of the last one I need. The Spring engine is amazing for example, is there another open source project of the source in current development? Or would Spring itself be enough (it certainly looks capable) to make it? Thanks in advance guys...

  • Is DevCon.exe still the best way to restart/power cycle USB ports after resuming from hibernation in

    - by ProfessionalAmateur
    I have a USB broadband card on my Windows 7 laptop. It loathes resuming from hibernation properly. Back in the XP days I would issue a call devcon.exe from the command prompt and restart the selected ports (Saves you having to manually unplug and plug back in your USB devices). Ive been trying this is Windows 7, but the UAC keeps getting in the way. I'll start a command prompt. Issue the devcon command, but UAC asks me if I really want to do this, when I click yes it opens a different command prompt and launches the command. After the command completed this new prompt window closes faster than the speed of light and I cannot see the results. So Im thinking there has to be a better way to do this in the Vista/Win7 world...?

  • Failed to load session gnome-fallback, after messing with metacity

    - by Carlito
    I am using Ubuntu 12.04 with gnome-session-fallback (Gnome Classic in the login menu). I wanted to remove window borders from metacity and stumbled across this post which basically changes window->mwm_decorated from TRUE to FALSE, which should remove the window borders in metacity. I know that it is also possible to change your GTK theme to one without window borders, but I wanted to try this solution. So I downloaded the source from my current metacity version (2.34.1) and changed that row. After compiling (./configure && make) I ran checkinstall which generates a .deb file from the source (had to change the version a bit to match the current one exactly). But after installing and loging out and back in, I couldn't load Gnome Classic. I get the error Failed to load session gnome-fallback. I could reinstall the old metacity which was still saved in /var/cache/apt/archives/, so everything is back where it was before. But I would like to mess around with metacity. Have I installed it correctly or did I forgot something? Are there any log files that I should check for solving this error? Thanks in advance!

  • Sharing business logic between server-side and client-side of web application?

    - by thoughtpunch
    Quick question concerning shared code/logic in back and front ends of a web application. I have a web application (Rails + heavy JS) that parses metadata from HTML pages fetched via a user supplied URL (think Pinterest or Instapaper). Currently this processing takes place exclusively on the client-side. The code that fetches the URL and parses the DOM is in a fairly large set of JS scripts in our Rails app. Occasionally want to do this processing on the server-side of the app. For example, what if a user supplied a URL but they have JS disabled or have a non-standard compliant browser, etc. Ideally I'd like to be able to process these URLS in Ruby on the back-end (in asynchronous background jobs perhaps) using the same logic that our JS parsers use WITHOUT porting the JS to Ruby. I've looked at systems that allow you to execute JS scripts in the backend like execjs as well as Ruby-to-Javascript compilers like OpalRB that would hopefully allow "write-once, execute many", but I'm not sure that either is the right decision. Whats the best way to avoid business logic duplication for apps that need to do both client-side and server-side processing of similar data?

  • Issues with Cinnamon?

    - by Corrodie
    I just recently switched my system over to Ubuntu 12.10, and decided on Cinnamon as my environment-- it all worked fine, at first. But I was poorly educated and started using Compiz and Emerald along with it--Setting both as replacements in startup processes. I now know, that's a big, big mistake. Now when loading Cinnamon, I am greeted to my background image, and only that. My only options seem to be to open a terminal. I was advised to attempt muffin --replace and mutter --replace Neither to any avail, the terminal closes, and I cannot load another one unless I completely reload. I went back to Unity, purged and autoremoved Cinnamon, emerald, and compizconfig, and attempted to reinstall Cinnamon, thinking that would solve the problem--no, it came back just as broken as before. So, I reinstalled ubuntu, then cinnamon---still broken. I'm assuming I must find a way to remove the replace commands-- but as I have no menu, I'm not positive I can do that. Is there any way I can access the startup processes via terminal? I'd think though, if I completely removed Cinnamon, all configurations would be gone too, so, it's just not making much sense. Is there some kind of reset I could possibly do? I've been browsing forums and questions here, all leading to things I'd already done, so, it can't hurt to ask for myself. I apologize if you would rather I have posted this over at mint. Next time, I will definitely check compatibility instead of assuming something just has to work. Any help is greatly appreciated, thanks! ****EDIT***** It seems although it didn't allow me to do it before, I was now allowed to access the settings and startup processes for Cinnamon via Unity, and, after quickly removing aforementioned processes- I'm up and running again.

  • Shutdown issue on persistent LiveUSB

    - by John K
    A) Downloaded Ubuntu to a Windows 7 temp directory from: http://www.ubuntu.com/download/ubuntu/download (Ubuntu 11.10 - Latest version / 32-bit). The output was a .iso file. B) Created a bootable USB stick using Universal USB Installer: http://www.pendrivelinux.com/universal-usb-installer-easy-as-1-2-3/. Did not select "Persistent file". Result: Tried it in a Dell Latitude D630 Dell laptop: works every time, many startups and shutdowns. C) Repeated B) but with "Persistent file" set. Works once or twice, but then, just locks on the Ubuntu splash screen. E) Downloaded LiveUSB Install from http://live.learnfree.eu/download, which created a file on Windows 7 called live-usb-install-2.3.2.exe. F) Ran the above installer with "Persistent file" to a 4GB ScanDisk (formatted) thumb drive. Result: Worked pretty good for a while. Shutdown and rebooted several times. Changed items like creating a new directories - all worked. Then: Setup an Admin account with a password and no auto login. On next reboot, it required the password and logged in correctly. Tried to shutdown via the top left icon - Shutdown menu option. Key issue: Would not shutdown, but would always go back to the login prompt. Could successfully login. Finally, shutdown (which just put me back to the login window), and hard shutdown with the power switch. Result: On reboot, just locks on the Ubuntu splash screen. Questions (note, very new to Linux): Did I shutdown wrong (I mean prior to the hard power off)? Is the persistence option very unstable, or am I doing something else completely wrong?

  • Can you add doubleclick macros to exisiting ads

    - by picus
    Setup: A few weeks back I made some very simple html5 "ads" to run on a few of our partner sites. They weren't paid ads as we also manage these sites, however there are a few of them, so I made a modular solution that is hosted on one of our web servers and included on each page via javascript which outputs an iframe. Each search (ad has a search box) or click appends a url param that we track using custom vars in Google Analytics. In essence, the ad is a HTML page served in an iframe via javscript. Problem: We have an opportunity to run these ads on a third party site, I had sent them a brief how-to for inserting them and they came back saying that: The creative code doesn't contain the %u macro. We can’t substitute the default click-through URL without it. I am somewhat familiar with doubleclick from a web developer's POV, i have inserted DC dart tags before and even have implemented the ad tool for publishers. I have not, however, actually ever created an ad for the doubleclick network before. I assume the publisher needs these tags to track clicks and hence charge us. However, they have not responded to me in regards to these questions. Are macros something I can just add to or replace the existing links with, or do I need to completely setup the ad with doubleclcik - a big issue in the short term given we do not have a advertiser's account set up with them. Thanks in advance
