Dual boot UEFI Windows 7 and Ubuntu 12.04 (both 64 bits). W7 entry doesn't appear in GRUB

- by Joe

After trying to install both OS during 2 days, I'm confused and getting mad... I have SSD 128 GB and HDD 500 GB both empty. My laptop is Asus K55VM. BIOS support UEFI. What I have done: Install new SSD (Samsung 830 128GB) Use GParted on liveCD to create new table of partitions (GPT) and create 3 partitions (in the SSD) for different purposes: Partition 1: 80 GB (w7); Partition 2: 30 GB (Ubuntu 12.04 -Just / -); Partition 3: 10 GB unused (for future extesion of the other partitions) Install Windows 7 (with UEFI) in Partition 1. This create: /dev/sda1 - 100 MB for System (UEFI boot I guess) - FAT32 /dev/sda2 - 100 MB aprox. for MSR /dev/sda3 - 79.800 MB aprox. for Windows7 data In this point everything works fine. I have W7. Now I install Ubuntu 12.04 amd64 (with UEFI) as follows: Install / in Partition 2 - /dev/sda4 30 GB ext4, and in the hdd I install /home and swap. I select bootloader in /dev/sda1 (where it's supposed to be the UEFI boot). I install updates and reboot. Problem: Now just appears grub menu with Ubuntu entries and not Windows 7. Alternative solution found: When I turn on laptop, before loading GRUB I press ESC key and appear BIOS boot, so I can select to boot the Windows partition, Ubuntu partition, DVD, USB, etc... but I think is not the best way to boot different OS. I've tried: sudo update-grub2 with no success. What can I do??

VPS hang when one Virtual CPU usage is 100%

- by garconcn

We are using Xen Center to manage all of our cPanel VPS servers. The hardware has two CPUs(Intel(R) Xeon(R) CPU [email protected]) and 32GB memory. Each hardware has 4 cPanel VPS and each VPS has 8GB memory and 4 Virtual CPUS. Every one or two months, one of the VPS server will hang because one Virtual CPU usage is 100% and it couldn't release the CPU unless we use force reboot. We have 10 similar hardware, and this cause our server down almost every day. We have tried to avoid the Statistics Processing and Fantastico update during the night, but the problem still happens randomly. I can not find anything in the server log when it hangs. Any clue? Thank you.

Forced to use Outlook Web Access, what are my options?

- by joon

My company just enforced an OWA update and disabled IMAP and POP3 access. I don't want to use the webmail, do I have any options? Forwarding is also disabled. I also don't look forward to installing thunderbird or anything else, which is what colleagues are doing. I'd be interested in running some sort of automation script that either forwards the emails, or notifies me somehow that there has been some activity. Disclaimer: This does not concern any illegal activity, as I work at a school. They are not explicitly preventing me from circumventing their bogus security imposition and have given me permission to do so, 'if I can find a way'. Which of course makes me want to do it even more.

Toshiba Equium A110-252 laptop won't boot Windows.

- by Drew Gibson

I have a Toshiba Equium A110-252 laptop (XP Pro) which stopped booting a couple of weeks ago. The symptoms are that the laptop would display its DOS Toshiba splash screen, then the Windows (XP) boot screen would display, then a very brief blue screen flash, then back to the boot options screen (offering safe mode, safe mode with networking etc, last known good config, etc... none of these work). I assumed a duff HD, and swapped it for a new one and reinstalled from a TrueImage backup. This worked until I installed windows updates I think (the backup was a few months old), and now the PC is doing the same thing. I have installed a third, old HD (60GB) with Ubuntu 11.04 on it, and everything is fine. PC boots and runs Ubuntu beautifully. I need Windows running on it though ! Given these symptoms, could it a windows update issue ? Or might I have a hardware fault still ?

pyexiv2 build error src/exiv2wrapper.hpp:32:29: error: exiv2/preview.hpp: No such file or directory

- by Jake

The other day I used apt-get install python-pyexiv2 on my ubuntu server, but it seems to have given me an old version. It's not compatible with the code I wrote in my local development environment so I'd like to update it. I downloaded the latest tar.gz from the website, extracted it and ran scons as per the readme. But it will not build, I get the error src/exiv2wrapper.hpp:32:29: error: exiv2/preview.hpp: No such file or directory I've also user apt-get to install libboost-python-dev and libexiv2-dev Can anyone help me on this?

Is there a chroot build script somewhere?

- by Nils

I am about to develop a little script to gather information for a chroot-jail. In my case this looks (at the first glance) pretty simple: The application has a clean rpm-install and did install almost all files into a sub-directory of /opt. My idea is: Do a find of all binaries Check their library-dependencies Record the results into a list Do a rsync of that list into the chroot-target-directory before startup of the application Now I wonder - ist there any script around that already does such a job (perl/bash/python)? So far I found only specialized solutions for single applications (like sftp-chroot). Update I see three close-votes for the reason "off topic". This is a question that arose because I have to install that ancient piece of software on a server at work. So if you still feel this is off-topic - leave a comment...

setting up my own name server

- by mmokh

I'm in the process of setting up my own name servers using BIND9, however I want to visualize the name server setup in relation to registrars and other name servers. Say I have a domain www.mydomain.com I setup my 2 name servers: ns1.mydomain.com - 192.168.0.1 ns2.mydomain.com - 192.168.0.2 1) How does the world know that my name servers are now at ns1.mydomain and ns2.mydomain. I read about setting up glue records at my registrar. Could you please elaborate on this, i.e. once i setup these glue records, can I now use my name servers in NS records for any other domain? For e.g. NS records for www.otherdomain.com - ns1.mydomain.com/ns2.mydomain.com 2) Given I setup the glue records as mentioned above, do I "have to" update mydomain.com NS records to point to my name servers? Can I keep mydomain.com NS records pointing to my registrars name servers, however use ns1.mydomain.com/ns2.mydomain.com as name servers for any other domain I own? Thanks

Windows Home Server Passwords Do Not Match [closed]

- by Ben Fulton

I have a Windows Home Server that chunks along just fine most of the time. I've never bothered to put it on a GPS and so it's vulnerable to power outages that happen a few times a year. This most recent time, it came back and seemed to be fine, but whenever I try to access a shared folder I get "Passwords do not match". They matched before the power went out, and I couldn't update the WHS password since I apparently didn't know the old one. How do I fix this?

My home partition slowly fills up until the system is unable to complete even simple tasks

- by user973810

So I have an awesome configuration on my home pc. My /home directory has its own partition. My home partition slowly fills up until the system is unable to complete even simple tasks. For example, when this issue has occured, I can load up firefox. It just pops up an error message saying that it cannot be done. Rebooting solves the issue. The strange thing is, I've run baobab and it doesn't notice a problem. There should be hundreds of gigabytes of data somewhere, but it doesn't see it. Does anyone have any idea of how I might troubleshoot this issue? I'm thinking I could do lsof but I've always found the output of that to be too much information. Maybe my drive is, like, dying. Edit: is there a /home analog of /var that gets cleared out at boot time? Maybe I could check in there next time I notice this problem to see if I can divine what's up. Update: I found the issue. my .xsession-errors file is filling up with Authentication deferred - ignoring client message Is there a way I can see what is causing this error and fix it?

Building modules with linux kernel for custom flavor

- by Chandan Apsangi

I followed the instructions given in the link: http://blog.avirtualhome.com/how-to-compile-a-new-ubuntu-11-04-natty-kernel/ for building a custom kernel and booting it. Everything works fine, except that when building it, I used the option skipmodule=true (as given in this link), so I guess the modules are not built for this kernel. I'm saying this because after I installed the image (using dpkg -i), when I run 'ls -l' in the /lib/modules/2.6.38-11-i5 folder, all the files/folders except the 'kernel' folder have got updated (Btw, I had built it last time and it had worked fine,this is an update on the same kernel source). So is there some option/command that I missed that exports the modules as well? Thanks for your help.

Using iTunes within Terminal Services 2008 R2 - Pitfalls etc

- by Kristiaan

I was hoping to get some further information on any possible Do's and Don't when it comes to installing, using and maintaining iTunes within a Termina Server environment. We have come across a situation in our company whereby some of our users who are using thin clients now need the ability to sync, update and manage their devices, previously they used either standard desktop systems or laptops so there was no issue with running iTunes. I have not found much information on the web about using iTunes within a Terminal Server Farm, Id like to find out if iTunes works within the environment, any known or common issues that occur due to running it like this.

No operating system found even when grub2 was reinstalled

- by Cruzer

I know there have been many variations on this question and have certainly tried to do my research. I don't really know what I'm doing so I would rather not take risks. I am trying to dual boot xubuntu and windows 7. I started out with xubuntu and just installed windows. Of course, the mbr got overwritten and windows didn't seem to recognize linux. So I booted to the live cd and rewrote the mbr. And of course, now I get the error "No Operating System Found" on startup. I have been following these tutorials to help me out. community.linuxmint.com/tutorial/view/245 unix.stackexchange.com/questions/96977/grub-wont-install ubuntuforums.org/showthread.php?t=2036730 Specifically, I ran these commands: # sdb2 is the partition with xubuntu sudo mount /dev/sdb2 /mnt # sdb1 is my boot partition sudo mount /dev/sdb1 /mnt/boot # not sure what this does, but ran it anyway... for i in /dev /dev/pts /proc /sys /run; do sudo mount -B $i /mnt$i; done sudo chroot /mnt #once chrooted grub-install /dev/sdb update-grub here's a link to my gparted https://www.dropbox.com/s/zpbbzh9z7k1l3pj/gparted.png EDIT--- didn't realize that the drive letters are different in the picture than in my code (its sda in the pic instead of sdb). I have been restarting a lot and sometimes the drive letters change and make my usb into sda.

Firefox hangs with java in Linux

- by Xolve

I am using Firefox 3.6 on Linux and I haveJava 6 update 15. Obviously I am using the newer plugin type. Whenever I open a page with Java applet it just becoms unresponsive and hangs. I tried with Chrome. I think it detects the Java plugin from mozilla's plugins folder. Due to multiprocess architecture it doesn't hang and shows the initial applet loading window but then it reports that the plugin has crashed. The only way I can run Java applets is to download the class file and make an html file and run the applet using applet viewer.

Updated 12.04 and now Xorg is dead from NVidia drivers

- by Xatolos

I updated (August 16) Ubuntu 12.04 today and while I admit I didn't look what was being updated, it was large enough to have had an NVidia update in it. Problem is later on when I turned on my laptop again it won't boot into a GUI, just to the terminal (which I don't really know much of how to do anything). Now I have been able to log in and type "startx" to start up the GUI and now its complaining that my NVidia driver (if I remember correctly) is listed as being version 304.(number) and the version installed/found is version 295.(number). I don't know how this happened and now I'm stuck. I have no idea how it happened and don't know how to fix. Does anyone have any ideas? I have only access to wifi internet and no idea how to log on without the GUI so getting a new NVidia package isn't something I would know how to do even... Any and all help would be highly appreciated. edit: If it helps, I'm using a ASUS G Series G53JW-A1 http://www.newegg.com/Product/Product.aspx?Item=N82E16834220861

How can I measure TCP timeout limit on NAT firewall for setting keepalive interval?

- by jmanning2k

A new (NAT) firewall appliance was recently installed at $WORK. Since then, I'm getting many network timeouts and interruptions, especially for operations which would require the server to think for a bit without a response (svn update, rsync, etc.). Inbound SSH sessions over VPN also timeout frequently. That clearly suggests I need to adjust the TCP (and ssh) keepalive time on the servers in question in order to reduce these errors. But what is the appropriate value I should use? Assuming I have machines on both sides of the firewall between which I can make a connection, is there a way to measure what the time limit on TCP connections might be for this firewall? In theory, I would send a packet with gradually increasing intervals until the connection is lost. Any tools that might help (free or open source would be best, but I'm open to other suggestions)? The appliance is not under my control, so I can't just get the value, though I am attempting to ask what it currently is and if I can get it increased.

Calling a webservice via Javascript

- by jeroenb

If you want to consume a webservice, it's not allways necessary to do a postback. It's even not that hard! 1. Webservice You have to add the scriptservice attribute to the webservice. [System.Web.Script.Services.ScriptService]public class PersonsInCompany : System.Web.Services.WebService { Create a WebMethod [WebMethod] public Person GetPersonByFirstName(string name) { List<Person> personSelect = persons.Where(p => p.FirstName.ToLower().StartsWith(name.ToLower())).ToList(); if (personSelect.Count > 0) return personSelect.First(); else return null; } 2. webpage Add reference to your service to your scriptmanager <script type="text/javascript"> function GetPersonInCompany() { var val = document.getElementById("MainContent_TextBoxPersonName"); PersonsInCompany.GetPersonByFirstName(val.value, FinishCallback); } function FinishCallback(result) { document.getElementById("MainContent_LabelFirstName").innerHTML = result.FirstName; document.getElementById("MainContent_LabelName").innerHTML = result.Name; document.getElementById("MainContent_LabelAge").innerHTML = result.Age; document.getElementById("MainContent_LabelCompany").innerHTML = result.Company; } </script> Add some javascript, where you first call your webservice. Classname.Webmethod = PersonsInCompany.GetPersonByFirstName Add a callback to catch the result from the webservice. And use the result to update your page. <script type="text/javascript"> function GetPersonInCompany() { var val = document.getElementById("MainContent_TextBoxPersonName"); PersonsInCompany.GetPersonByFirstName(val.value, FinishCallback); } function FinishCallback(result) { document.getElementById("MainContent_LabelFirstName").innerHTML = result.FirstName; document.getElementById("MainContent_LabelName").innerHTML = result.Name; document.getElementById("MainContent_LabelAge").innerHTML = result.Age; document.getElementById("MainContent_LabelCompany").innerHTML = result.Company; } </script> If you have any question, feel free to contact me! You can download the code here.

Can ping/nmap server, nothing else

- by lowgain

I was SSHed into our ubuntu LAMP server , and was just doing a svn update, which hung. I disconnected, and since then, I have not been able to SSH in or view any of our websites (neither from my network or through a remote machine). I would have just assumed the server went down, but I can ping the machine and get really quick responses. Using nmap on the box shows all the normal ports open, so I am confused This server is hosted remotely in a datacenter, do I have any remaining options except contacting them for support? Thanks!

Pinnacle Studio 14 Importer crashes on Windows 7 x64

- by Tuminoid

Pinnacle Studio 14 Importer crashes on Windows 7 x64, thus I'm unable to import videos from my camcorder. I've Googled around and it seems to be a problem with x64 support in the program, but there is no info if it can somehow be remedied with Compatibility settings, XP mode. Further Googling got me this link, and none of the tips in site it links help. I've got no idea what ObjectDoct Plus 2 is (no a program or service installed by that name) which he claims causes the problem. Is that ObjectDoct critical to Pinnacle Studio and how to get rid of it (or any other advice how to make Studio 14 work on x64). UPDATE: 1) XP mode doesn't help as it doesn't handle Firewire, which is how my Canon HV20 must be connected to transfer HDV from tape. 2) I don't have that ObjectDock installed. 3) I don't wanna re-buy PS15 just to get this solved as PS14 should be able to do it.

PHP Runs Very Slow on IIS7. Need Help optimizing our config

- by Kendor

Am running a PHP based web app on our Windows 2008 cloud-based server. The app, which runs fine outside of our environment (e.g. a different IIS server), but is VERY slow in our environment. Based on googling this is a relatively common situation. I installed PHP and MySQL via the IIS web deployment method... Here's our setup: Windows 2008 Server Enterprise SP2 (32-bit) Microsoft-IIS/7.0 MySQL client version: mysqlnd 5.0.8-dev - 20102224 $Revision: 321634 $ PHP extension: mysqli Update for IIS 7.0 FastCGI Windows Cache Extension 1.1 for PHP 5.3 I had read elsewhere that ipv6 might be an issue, so I turned this off on the network adapter. The app is using: localhost as its connection Be easy on me, as I'm a bit green about some of these components... Also, rewriting the PHP app or modifying it is NOT an option. I'm reasonably SURE that our config is the issue.

Change default code page of Windows console to UTF-8

- by Regent

Currently I'm running Windows 7 x64 and usually I want all console tools to work with UTF-8 rather than with default code page 850. Running chcp 65001 in the command prompt prior to use of any tools helps but is there any way to set is as default code page? Update: Changing HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Nls\CodePage\OEMCP value to 65001 appear to make the system unable to boot in my case. Proposed change of HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor\Autorun to @chcp 65001>nul served just well for my purpose. (thanks to Ole_Brun)

Webcam on Sony Vaio on Win 7 problem

- by Norm

Anyone know where I can get a Win 7 32Bit driver for my Web Cam (Vaio VGN-CR11H/B) ? I changed operating system from Chinese Vista to English Win 7 Update: Windows 7 will not detect the cam, but I just read the Sony Europe site and it gives me some ideas to try. I can dual boot this Sony laptop: with Chinese Vista, the camera works but IE8 does not work. I cannot read Chinese to fix the Internet access issue, but I can get the computer online and Skype works. When I boot with the new Win 7, IE 8 works great, but the cam doesn't work (mic and speakers work). Very perplexing problem.

How can I test linkable/executable files that require re-hosting or retargeting?

- by hagubear

Due to data protection, I cannot discuss fine details of the work itself so apologies PROBLEM CASE Sometimes my software projects require merging/integration with third party (customer or other suppliers) software. these software are often in linkable executables or object code (requires that my source code is retargeted and linked with it). When I get the executables or object code, I cannot validate its operation fully without integrating it with my system. My initial idea is that executables are not meant to be unit tested, they are meant to be linkable with other system, but what is the guarantee that post-linkage and integration behaviour will be okay? There is also no sufficient documentation available (from the customer) to indicate how to go about integrating the executables or object files. I know this is philosophical question, but apparently not enough research could be found at this moment to conclude to a solution. I was hoping that people could help me go to the right direction by suggesting approaches. To start, I have found out that Avionics OEM software is often rehosted and retargeted by third parties e.g. simulator makers. I wonder how they test them. Surely, the source code will not be supplied due to IPR rgulations. UPDATE I have received reasonable and very useful suggestions regarding this area. My current struggle has shifted into testing 3rd party OBJECT code that needs to be linked with my own source code (retargeted) on my host machine. How can I even test object code? Surely, I need to link them first to even think about doing anything. Is it the post-link behaviour that needs to be determined and scripted (using perl,Tcl, etc.) so that inputs and outputs could be verified? No clue!! :( thanks,

Git Branch Model for iOS projects with one developer

- by glenwayguy

I'm using git for an iOS project, and so far have the following branch model: feature_brach(usually multiple) -> development -> testing -> master Feature-branches are short-lived, just used to add a feature or bug, then merged back in to development and deleted. Development is fairly stable, but not ready for production. Testing is when we have a stable version with enough features for a new update, and we ship to beta testers. Once testing is finished, it can be moved back into development or advanced into master. The problem, however, lies in the fact that we can't instantly deploy. On iOS, it can be several weeks between the time a build is released and when it actually hits users. I always want to have a version of the code that is currently on the market in my repo, but I also have to have a place to keep the current stable code to be sent for release. So: where should I keep stable code where should I keep the code currently on the market and where should I keep the code that is in review with Apple, and will be (hopefully) put on the market soon? Also, this is a one developer team, so collaboration is not totally necessary, but preferred because there may be more members in the future.

Windows 7 security and Avast antivirus turned off by themself

- by Simon Verbeke

I was just browsing around when at once I got messages that UAC, windows defender, Avast, etc. got turned off, without me doing anything. Then my PC turned by itself. I'm now running virus scans and I checked my eventlogs, but found nothing yet. Windows Update also failed to install a new definition after I rebooted. Any idea what this could've been? EDIT: Forgot to mention that everything was turned on again after rebooting. I have since the reboot got nothing abnormal.
