• What version was installed? x64 or i686? What's the difference exactly?

  - by Seppo

  Okay, so heres my problem. I recently started migrating several services to individual VMs on my box, using VirtualBox 4.1. I created a new VirtualBox VM with guest type "Ubuntu (64 Bit)". I've already done this before and it worked like a charm. I then installed unbutu server (12.04) from the exact same dvd image. All the time I thought that it should have installed x64. I already put a few hours work into the new VM, migrating the webserver and mail system etc. Today I tried installing a x64 piece of software and it suddenly told me that it needed x64 and I had only i686. I checked uname -a and this is what it gave me: Linux hostname 3.2.0-29-generic-pae #46-Ubuntu SMP Fri Jul 27 17:25:43 UTC 2012 i686 i686 i386 GNU/Linux Any guesses what went wrong? All the time I was thinking I had a x64 system. Any way to move to a "real" x64? I have a second VM on this host which is running x64 just fine .. P.S.: grep --color=always -iw lm /proc/cpuinfo returns lm among the flags.

• PHP hosting some info required [closed]

  - by mtk

  I have recently given a control of newly bought hosting space and the domain account. There is a technical team from the hosting site to help out with problems, but that is a long process, i.e. log a ticket, wait for a long time, and I don't get the correct answer in the first shot. I was wondering, if anyone has any helpful guide and how one must go with hosting a site. Any info that must be know w.r.t to cpanel? Any other useful stuff if any one has, or could point me to ? Just to give a few difficulties: The same php code working well on local machine, giving error on remote as "File not found". The file is present indeed as I have ftp'ed all the files correctly. session_start error are outputted to html page with warning "Header already sent". and many more technical things, that work well on local but not on actual hosting server. So, if anyone has any helpful stuff in this reference, as to what all changes are required or what a programmer must be aware from a hosting perspective, please let me know. Note I am hosting a PHP site with mysql db, on a shared environment.

• MySQL can only log in as root, even after creating new users with their own database

  - by ionFish

  Problem: I just set up a Debian Wheezy installation for testing, and installed the LAMP packages and PMA. I can log in as root with my pre-defined password, create/edit/delete both databases and users. The problem comes when I create a new user 'something', set a password for it, and grant it all privileges on a table 'something' (same as the username). Upon connecting, it denies access to the user. Details: Host: localhost using MySQL 5.5.24-8 Creating user: CREATE USER 'something'@'%' IDENTIFIED BY '***';GRANT USAGE ON *.* TO 'something'@'%' IDENTIFIED BY '***' WITH MAX_QUERIES_PER_HOUR 0 MAX_CONNECTIONS_PER_HOUR 0 MAX_UPDATES_PER_HOUR 0 MAX_USER_CONNECTIONS 0;CREATE DATABASE IF NOT EXISTSsomething;GRANT ALL PRIVILEGES ONsomething.* TO 'something'@'%'; Checking privileges: GRANT USAGE ON *.* TO 'something'@'%' IDENTIFIED BY PASSWORD '*92F9DAF5F5129554509489FDB6A433510223C799'; Result: Access denied for user 'something'@'localhost' (using password: YES) More Info: I use this same exact procedure for the Squeeze distribution, and it works perfectly. Is there a chance it's because of Wheezy, or something else? I need to continue using Wheezy because of the updated packages (for this test server -- the others work fine), so 'just use Squeeze' is not an option. Note: I HAVE tried flush privileges; to no avail.

• I deleted all files and folders (including hidden) from /home/username/ now in big trouble

  - by jeffery_the_wind

  I am logged into a remote ubuntu server, and I accidentally erased the entire /home/username/ directory for the current user. The only thing left is a hidden directory called .gvfs. I don't need anything of the Documents/Music/etc. Now it is not letting me cd into the /var/www/ directory, which has permissions 666 and it is owned by the current user. I am afraid to disconnect from my ssh session because I don't know if I will be able to get back on. Have I permanently created a problem? Is there a way I can replace the most important files to the /home/username/ directory? Thanks! ** EDIT ** Thanks everyone for the help. I figured the problem with cd into the /var/www/ was actually my permissions in the /var/www/ directory. It was set to 666, changed it to 755 and everything was good again. It doesn't look like anything systematic was ruined by deleting the contents of the user folder.

• How do I make a Live USB without destroying my Windows computer?

  - by user71089

  Unlike every other post I have read, let me begin by saying that I am TERRIFIED of destroying my Windows 7 home system in the attempt of making a bootable Ubuntu Thumb Drive. I very specifically DO NOT want to attempt configuring a dual boot system. What I am seeking is a portable operating system on a thumb drive, through which I can run my COREL software via VirtualBox-4.1.16-78094-Win. I want to be able to use my own software on my work computer without any worries about screwing up the host system anywhere I go. Supposedly, I just made a bootable Thumb drive, having successfully loaded the ISO for ubuntu-12.04-desktop-i386 using Pendrivelinux's Universal-USB-Installer-1.9.0.1 However, all that I get is a Thumb Drive that wants to install Unbutu onto my PC's HDD. I am not finding any clear path to this end in the posts I am reading. Like it or not, Windows is a fact of life for me. The goal is to be able to use my software on my work PC without doing anything intrusive that will cost me my job. If I have a meltdown on my PC at home trying to make this happen, it will be nearly as bad. Is this even Do-Able? Can the process be made clear? Thank You, Ubuntu World ...!

• Wireless does not work 12.10

  - by superkoop

  My primary issue is that my wireless does not work after I installed 12.10. The output to rfkill list all: 5: hci0: Bluetooth Soft blocked: no Hard blocked: no The output to lshw -class network is: *-network description: Ethernet interface product: 88E8040 PCI-E Fast Ethernet Controller vendor: Marvell Technology Group Ltd. physical id: 0 bus info: pci@0000:09:00.0 logical name: eth0 version: 12 serial: 00:21:9b:d6:46:51 size: 100Mbit/s capacity: 100Mbit/s width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical tp 10bt 10bt-fd 100bt 100bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=sky2 driverversion=1.30 duplex=full ip=192.168.1.102 latency=0 link=yes multicast=yes port=twisted pair speed=100Mbit/s resources: irq:44 memory:fe8fc000-fe8fffff ioport:de00(size=256) *-network description: Network controller product: BCM4312 802.11b/g LP-PHY vendor: Broadcom Corporation physical id: 0 bus info: pci@0000:0b:00.0 version: 01 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list configuration: driver=b43-pci-bridge latency=0 resources: irq:17 memory:fe7fc000-fe7fffff The output to lspci -nn for the pertinent information is: 0b:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01) Thus, it seems the solution would be to run: sudo apt-get install linux-headers-generic sudo apt-get install --reinstall bcmwl-kernel-source sudo modprobe wl However, I do not currently have access to an ethernet connection, as I am currently only able to use verizon wireless 3g internet. Thus, is there a way to set up ICS with a Vista machine so that I can access the internet by using the Vista machine as the host? Or, is it possible to fix this by downloading the important packages in vista and moving them to ubuntu via USB drive?

• cookie not being sent when requesting JS

  - by Mala

  I host a webservice, and provide my members with a Javascript bookmarklet, which loads a JS sript from my server. However, clients must be logged in, in order to receive the JS script. This works for almost everybody. However, some users on setups (i.e. browser/OS) that are known to work for other people have the following problem: when they request the script via the javascript bookmarklet from my server, their cookie from my server does not get included with the request, and as such they are always "not authenticated". I'm making the request in the following way: var myScript = eltCreate('script'); myScript.setAttribute('src','http://myserver.com/script'); document.body.appendChild(myScript); In a fit of confused desperation, I changed the script page to simply output "My cookie has [x] elements" where [x] is count($_COOKIE). If this extremely small subset of users requests the script via the normal method, the message reads "My cookie has 0 elements". When they access the URL directly in their browser, the message reads "My cookie has 7 elements". What on earth could be going on?!

• Using Git with TFS projects

  If you having been following the updates to CodePlex over the last several months you will have noticed that we added support for Git source control. It is important to the CodePlex team to enable developers to use the source control system that supports their development style whether it is distributed version control or centralized version control. There are many projects on CodePlex that are using TFS centralized version control. But we continue to see more and more developers interested in using Git. Last week Brian Harry announced a new open source project called Git-TF. Git-TF is a client side bridge that enabled developer to use Git locally and push to a remote backed by Team Foundation version control. Git-TF also works great for TFS based projects on CodePlex. You may already be familiar with git-tfs. Git-TFS is a similar client side bridge between Git and TFS. Git-TFS works great if you are on Windows since it depends on the TFS .Net client object model. Git-TF adds the ability to use a Git to TFS bridge on multiple platforms since it is written in Java. You can use it on Mac OS X, Linux, and Windows, etc. Since you are connecting to a TFS Server when using Git-TF make sure you use your CodePlex TFS account name: snd\YOUR_USERNAME_cp along with your password. At this point, you will need to be a member of the project to connect using Git-TF. Resources Git-TF Getting Started Guide Download: Git-TF Git-TF Source on CodePlex

• Cannot connect to Internet via Wifi

  - by lvogel

  I have a laptop that's currently configured as a dual-boot. The problem: I cannot connect to the Internet in the home wireless network through Ubuntu in the apartment where I currently live. The strange part: I can connect to it just fine through Windows (as right now), and I can use the Internet through Ubuntu on this computer with all the other wireless networks I have tried. The problem is only with this particular combination. The only possible explanations I can think of are either that this network is WPS, or that it's a driver problem--Vodafone router. The router 'sees' the computer--and it says it's connected; however, I keep getting prompted for a password, and I enter the key that works with Windows, but in Ubuntu it just keeps asking for it repeatedly, and I can't access the Internet. I don't have an ethernet cable at the moment, but if someone would be so kind as to ask me questions I will gladly answer, and if you have suggestions, I will do them--the only thing is, I am subletting this apartment from someone who is away on vacation, so I don't want to screw with the router settings unless I know what I'm doing! - I do not have Wicd - Yes, I have the router's information (key works in Windows) - Feedback of lshw says that the wireless card is Ultimate N Wifi Link 5300, vendor: Intel Corporation, physical id: 0 ,etc. The first two commands I was told to try work OK, but when I typed sudo ifconfig wlan0 essid ..... I got back 'essid: Unknown host' Would my question be better on the Ubuntu forums than here on AU?

• Hosting and scaling a Facebook application in the cloud? [closed]

  - by DhruvPathak

  Possible Duplicate: How to find web hosting that meets my requirements? We would be building a Facebook application in Django (Python), but still not sure of where to host it economically, and with a good provision to scale in case the app gets viral. Some details about the app: Would be HTML based like a website,using django as a framework. 100K is the number of expected pageviews in a day, if the app is viral. The users will not generate any media content, only some database data will be generated by them. It would be great if someone with more experience can guide on following points: A) Hosting on Google app engine or Amazon EC2 or some other cloud like RackSpace : Preferable points found in AppEngine were ease of deployment, cost effectiveness and easy scaling. For EC2: Full hold of the virtual machine,Amazon NoSQL and RDMBS database services in case we decide to use them. B) Does backend technology affect monthly cost? eg. would CPU and memory usage difference of Django over , for example , PHP framework like CodeIgnitor really make remarkable difference in running costs. (Here is the article that triggered this thought process : http://journal.dedasys.com/2010/01/12/rough-estimates-of-the-dollar-cost-of-scaling-web-platforms-part-i#comments) C) Does something like Heroku , which provides additional services over Amazon EC2, prove to be better than raw cloud management? It is not that we are trying for premature scaling, we just want to have a good start so that we are ready to handle unpredicted growth and scale.

• Release Notes for 5/18/2012

  Here are the notes for this week’s release: Pull Requests We’ve added the ability to see the snippets of code where a user commented inline in the discussion of pull requests. You can also add another line comment directly from the discussion area, rather than navigating to the code diff viewer. Note that there’s currently a known issue where the line associated with the comment isn’t being properly differentiated for existing pull requests (the line in the middle of each diff preview should be bolded). Apologies for the inconvenience! As part of this work, we also took some time to clean up our diff viewer UI to remove the dots and introduce a new color scheme where green is used for added lines. Bug Fixes Fixed an issue affecting the ability to assign pull requests. Fixed an issue where managing various team resources for a project was not working in Chrome or Firefox. Fixed an issue where a project’s RSS subscribe dialog popped up in the wrong place. Fixed an issue where editing wiki anchor links would insert extra characters, resulting in broken links. Fixed an issue where project logos did not display correctly when browsing the site with https in Chrome or Firefox. Fixed an issue where users could encounter errors when deleting remote Git branches. Fixed an issue affecting the ability of fork collaborators to push changes to the fork. Fixed an issue where the advanced work item filters would not persist when navigating through result pages. Fixed an issue where the issue tracker notifications link was not clickable in Chrome. Fixed an issue where pull request comments with line breaks would not be formatted properly when viewing the pull request. Other We upgraded our Git servers to version 1.7.10.1.

• CentOS drive mapping? [on hold]

  - by DroidOS

  This is the first time I am posting on this particular StackExchange forum and I hope that I am using the right one for the present question. Briefly, this is what I need to do I am running a web service where users can, amongst other things, upload and store files on the server. What I want to do is to hive off user file storage to a different location so my server (CentOS 64 bit) can concentrate on what it does best - server side scripting and database management. As things stand all user files go into subdirectories in a folder called stash that lies above DOC_ROOT. What I would like to do is Transparently detect all attempts to read/write to stash/sub_folder and get/set file data on a remote server - ideally the latter would be one which replicates files like a CDN so they can be delivered from the closest/fastest location based on where the user's location. Even nicer would be if for all read accesses I could provide a URL that allows the user's browser to fetch the relevant file directly without having to funnel them via my server. I am a relative newbie when it comes to this sort of thing so I hope that I have phrased this question adequately well. From the little searching I done I gathered that WebDAV can be used to map drives to a different location on the web so perhaps that is a starting point. But if that will work I need to Establish how to get WebDAV up and running on my CentOS 64 bit server. Ideally, identify a service that allows this kind of file storage and provides an API I can use in my own scripting. I'd much appreciate any help with this.

• Drupal site Instant Messaging [migrated]

  - by pthurmond

  I am trying to find a module or a standalone solution that I can turn into a module that will allow me to have an instant messaging system like Facebook does on a Drupal site that I am working on. I have never setup a chat system before. My particular requirements are rather stringent. It needs to be a solution where we host the chatting server (if one is needed separate from the website itself). It must use the site's login state (can't use an external system at all, that means no GTalk, Yahoo IM, or AIM). It also must be able to handle up to 1,000 users at any given time. I have looked through the Drupal community and I tried the DXMPP module, but it requires Jquery UI 1.8 and that doesn't work with all of the other things that my site uses (such as Homebox). We do have a Jabber server already setup and ready to go. Does anyone have any thoughts or options here? Thanks! EDIT: We are using Drupal 6.

• Mobile (Portable) Website

  - by johnny_s

  I have an online presentation to do next week and I have it all ready to go. The website is html and css only (no db), and currently resides on my shared hosting account. Now although my shared hosting is (relatively) reliable, I have noticed that recently they have been making some changes and my website has been unavailable at times. I don't want this to happen to me on the morning of my presentation, so I am asking what is the best way to prepare for such a thing? My domain is www.presentation.mydomain.com and I would like to keep this if possible (even if issues arise). I have been thinking of a few alternatives; host my site on two different domains or servers (but what about domain name)? have a portable XAMPP version on a USB (again, domain name)? possible fail-over site/location? Any advice or suggestions are welcome. Update Presentation will be carried out on their laptop, not mine. So I am unable to install any software.

• For what purpose I can use c++ to increase my skills?

  - by user824981

  I want to learn new things. Initially I was a PHP programmer. Then I thought it was not enough. Then I started learning Java thing. It took me 3 months to learn. Java, J2EE, Spring, Hibernte, Spring Security, Spring Roo and many design patterns MVC and stuff like AOP, DI . I never knew that before but I got the idea what J2EE. After 3 months, I just made a simple page with Registration form integrated with Spring Security. I wanted to make one complete project in it but that was too much for me and I didn't want spend more time on it as then i need to host that as well so I left that. Then I started learning Python and made few sys admin scripts and then Django and now I am finishing a complete web app in Python. Now I want to learn C++, but before that I need to find out what i can do with it. Just like I know Python is very useful because I have my own servers so I can write scripting and websites so Python is good for me. But I am confused in which areas C++ can help me. I don't want to end up like I have with Java where either I have big projects or nothing for day to day use.

• Windows Server or Linux for final project

  - by user1433490

  A few weeks ago I came up with an idea to develop a mobile app which will direct students in my university to the nearest printer availiable. The whole thing is part of my final project. The Android based app will need to perform the following tasks: The user's location in the campus is sent to the server. Assume this part works just fine. The server sends an SNMP request to the printers in the user's vicinity. I'll probably use PHP or Python for that part. The data requested by SNMP is processed and sent back to the client My question concerns the server. The university's IT manager offered me a designated server for development, which sounds great. Now I need to choose which OS I want installed on the server - Windows server or Linux (don't know which versions). I don't have any server programming/operating experince, but generally speaking I feel more comfortable in Windows enviroment (just because that has always been my OS). I don't have much time for learning a new OS, but when does it make sense generally to host or develop server side applications on a Windows environment versus a Linux environment?

• What tools do I have to disuade users from using the same password with similar systems?

  - by Resorath

  I'm building a web application that connects to other web services (using strictly anonymous binding, so no user passwords are being used). However the web application maintains its own users itself, and is required to ask certain details such as e-mail addresses and public linking information to these other web services (for example, a username but not a password). I want to deter or prevent users from reusing passwords in my application that they have also used in the applications I'm linking to. For example, if I ask for their e-mail and provide me with their gmail address, I don't want them using their gmail password for my system. Another example would be reusing a password to a linked system in which they also gave me their username. One idea I had was to simply try using the information they gave me, along with the password they are trying to store and log in to these external web applications to test the password - then immediately unbind if I was successful and ask the user to use a different password. However I suspect there is a host of morale and legal issues there. The reason this is a big deal to me is accountability. My application is simply not funded enough to invest properly in security around user passwords. A salted, hashed password in a public SQL-like database is as secure as it gets. So if passwords and linked usernames or e-mails get out, I don't want my userbase compromised.

• [LINQ] Master&ndash;Detail Same Record (I)

  - by JTorrecilla

  PROBLEM Firstly, I am working on a project based on LINQ, EF, and C# with VS2010. The following Table shows what I have and what I want to show. Header C1 C2 C3 1 P1 01/01/2011 2 P2 01/02/2011 Details 1 1 D1 2 1 D2 3 1 D3 4 2 D1 5 2 D4 Expected Results 1 P1 01/01/2011 D1, D2, D3 2 P2 01/02/2011 D1,D4   IDEAS At the begin I got 3 possible ways: - Doing inside the DB:  It could be achieved from DB with a CURSOR in a Stored Procedure. - Doing from .NET with LOOPS. - Doing with LINQ (I love it!!) FIRST APROX Example with a simple CLASS with a LIST: With and Employee Class that acts as Header Table: 1: public class Employee 2: { 3: public Employee () { } 4: public Int32 ID { get; set; } 5: public String FirstName{ get; set; } 6: public String LastName{ get; set; } 7: public List<string> Numbers{ get; set; } // Acts as Details Table 8: } We can show all numbers contained by Employee: 1: List<Employee > listado = new List<Employee >(); 2: //Fill Listado 3: var query= from Employee em in listado 4: let Nums= string.Join(";", em.Numbers) 5: select new { 6: em.Name, 7: Nums 8: }; The “LET” operator allows us to host the results of “Join” of the Numbers List of the Employee Class. A little example. ASAP I will post the second part to achieve the same with Entity Framework. Best Regards

• determine an application's process name on linux (ubuntu)

  - by Jacob

  This is the situation: Working on (the next version of) a Unity quicklist editor, I would like to add a reliable way of "restarting" launcher icons. To do so, I need to remove the icon (editing gsettings) and replace it on the same position. So far no problem. However, if the application in question is running, user will possibly lose data, as the application will quit when it's icon is removed from the launcher. What I need is a reliable way to find an application's process name, to let the editor check in the list of running processes if the application is running, and send a warning message to the user that the icon can not be restarted if the application is running. What i did so far is make the editor look into the desktop file, to read the command, also read the command, stripped from the directory section, and furthermore look into possible remote scripts the desktop file command might refer to, looking for strings starting with "./" Although te method seems to work well with all applications I tested it on, I have the feeling there must be an easier way to cover the problem in an "all in one" way... Is there? also suggestions to catch more exceptional situations are welcome!

• AR9485 wireless card loses ability to connect after hibernation

  - by DrewDiezel

  This has happened twice now, the first time it happened I just reinstalled Ubuntu. The only things that I've been messing with in terms of networking, have been restarting the network-manager service after I resume from hibernate (because it never works right after resume, but restarting the service fixes that), and changing my mac address with ifconfig wlan0 down && ifconfig wlan0 hw ether 11:22:33:44:55 && ifconfig wlan0 up. using tail | dmesg returns a bunch of attempts to connect, saying something like authenticating ... okay you're connected! now I'm going to just disconnect because I feel like it. (reason=3). Any ideas? If it helps maybe I'll add a picture of the tail|dmesg output later. My wireless drivers are as follows: Atheros AR9485 Wireless Network Adapter Hamachi Network Interface Microsoft Virtual Wifi Miniport Adapter Realtek PCIe GBE Family Controller VirtualBox Host-Only Ethernet Adapter Here is a pastebin of some terminal outputs that could help. Also, the reddit thread has a few answers, for anyone curious. It's located here. It is entirely possible that it's just my school wifi blocking out my laptop, and my home wifi sucks. Wifi does work at places other than my home and school, however my phone can connect to both places. Here is a pastebin of the results of the wireless-info script.

• What differences should I know? I just upgraded to 13.10 from 10.10 [on hold]

  - by test

  I ran Ubuntu 10.10 for a long time because I liked the menu style. The change in GUI with the upgrades drove me nuts but I finally gave in and downloaded Saucy Salamander 13.10 x64. It's a fresh install running as a virtual machine guest in VMWare Workstation 9 on a Windows 7 x64 host. Well it looks like all those icons are still there on the side which I would be OK with if there were some way to bring back my menus. I have no organized way of accessing things now, or do I? That is the purpose for this question, maybe there is some functionality I just can't find but is there. Also all my fine tuning was gone. I used to be able to change DPI but that's gone. I went ahead and installed Unity Tweak Tool via sudo apt-get install unity-tweak-tool but I couldn't find an icon for it after I installed it.. because again no menu. So I did a search for it and found it there. I've changed the font and which side the window buttons appear on which is good enough for now. Anyway... any suggestions you may have for me I'm game. I'm a Windows 7 user primarily but I use Ubuntu every once in a while. I really liked the old style where everything was categorized like for Applications there was Accessories, Games, Graphics, Internet, Office, Sound & Video, Wine.
