  • Is it possible to extend partition in which I have installed Ubuntu

    - by Santosh
    Before installing my current Ubuntu Oneiric Ocelot I was having 3 partitions on my hard drive (each in NTFS, and divided in 21GBs, 10GBs and 37GBs; approx 80GB). I put in the DVD in DVD-ROM and booted up with it. I was prompt whether to install Ubuntu side by current operating system (Windows 7) or totally remove all operating system. I choose to install side by the current operating system. In next screen I took one of my partition (the one which was of 37GB) and totally formatted it. Then created a ext4 file system of 10GBs on it (here 'it' means partition that was of 37GB, not whole HDD). While proceeding I was asked to make swap partition so I created another swap partition of 5GBs. I have Ubuntu installed, but now I am regretting about that 10GB, I should have done it more since I have much more space on my hard drive. And I have 22GBs of my hard drive useless (neither it is in ntfs nor ext4). I want to increase the size of ext4 partition in which I have installed my Ubuntu; from 10GB to something more.

  • Can I install new version of Ubuntu in spair RAIDed partition with unetbootin

    - by artfulrobot
    I have Ubuntu 11.04 running on my home desktop which has 2 hard drives mirrored by RAID. The drives are partitioned with a big data partition, a swap partition and a couple of 20Gb partitions for OSes, one is 11.04 which is in use, and the other is kept spare for installing a later version. Which is what I'd like to do now. The idea of a 2nd partition for new OS is that I can try it, and if it's problematic, I can boot back into the original one - the machine is shared with others, so I need it to stay available! I have had horrible problems with software RAID after using a Live USB stick - basically it messes up the internal numbering of the RAID drives or something, anyway, the result is you can't boot after using it :-( and have to spend ages re-assembling the arrays, trying to remember grub commands etc etc. Quite a shocker when you consider booting from a Live USB is supposed not to affect the existing system. As I'm installing in a RAIDed disc, I would typically use the Alternative install (sad to hear that this is going to be dropped in future). However, I think I might be able to use unetbootin to trick the system into working on top of the existing system that understands RAID, with the normal ISO? If unetbootin loads from drives that are already understood to be RAIDED, then presumably it will only see md0... instead of sda, sdb... and as long as I don't need to repartition (I don't) it should be fine, right? Or is that just plain foolishness? Please tell me before I end up with a dead system (again!)

  • Installing 13.04 on an EFI partition - Share with Windows 8?

    - by mengelkoch
    Information I've found here suggests that for my system, I need to install 13.04 into an EFI-type partition, since it needs to boot as UEFI. I also understand it is advisable to have only ONE EFI partition on the disk; I've read here that it is OK for Ubuntu and Windows to share the same partition (please confirm). When I try to install into the existing EFI drive, I get the message "No root file system is defined. Please correct from partitioning menu." Do I change the EFI boot partition to another type? Doesn't that defeat the purpose? If I change it to Ext4 Journaling File System, I am given the opportunity to define the '/' Mount point. I haven't proceeded beyond this point for fear I am going to destroy Windows 8 by altering this partition. BTW, I created three partitions in Windows before installing, per the helpful response to my previous question. But if I try to install into the partition I created for Ubuntu, I get the "No root file system..." error again.

  • Ubuntu (i386 - 32bit) 12.04 LTS [DESKTOP] - Freezes During Preparing to Install

    - by Michael Ecklund
    I know this is for the Desktop version of Ubuntu, but I definitely plan on installing the server as well. I just want a GUI to manage my server. Here is what I have done: Placed Ubuntu i386/32bit 12.04 LTS [DESKTOP] disc in the disc tray. The disc loads fine. Clicked install Ubuntu. Without checking the download updates while installing or install this third-party software. Clicked continue. Mouse cursor turns to spinning circle and remains a spinning circle while the screen freezes its place at "Preparing to install Ubuntu". I tried not checking any of the boxes and clicking continue. I tried checking Download updates while installing. I tried checking Install this third-party software. I tried checking BOTH Download updates while installing AND Install this third-party software. Does anyone else face this very same issue? Is there a workaround for this problem? Do I need to use a lower version of Ubuntu? If so, which version do you recommend for my system specifications? My system meets the system requirements. Here are my exact system specifications. (Custom modifications: 320GBx2 HDD && 256MB AGP GFX card && 1GBx2 RAM)

  • SQL Server Express 2008 R2 Installation error at Windows 7

  • Why does System.Web.Hosting.ApplicationHost.CreateApplicationHost throw System.IO.FileNotFoundExcept

    - by Scott Langham
    I saw something about needing to have the assembly available for the type of the first argument passed to the function. I think it is, I can't figure out what am I missing. This code is in a service. I was running the service under the 'NETWORK SERVICES' user account, when I changed the account to that of the session I was logged on with it worked ok. But, what's the difference, and how can I get it to work for the NETWORK SERVICES user.

  • Roadblocks in creating a custom operating system

    - by Dinah
    It seems to me that the most common overly ambitious project that programmers (esp. Comp. Sci. grads) try to tackle is building your own operating system. (Trying to create your own programming language + compiler is probably even more common but not nearly as ambitious.) For those (like myself) foolish enough to try: aside from the sheer size, what are the biggest *gotcha*s or unexpected roadblocks you've encountered in trying to create your own OS from the ground up? Edit: A great OS question: http://stackoverflow.com/questions/43180/how-to-get-started-in-operating-system-development/

  • How can I make it difficult to install a new operating system on a certain computer?

    - by D W
    I want to host a website on a desktop computer running Ubuntu with a Windows virtual machine. I will give away the computer in exchange for a number of months of remote web hosting. I want to add some kind of lock (hardware or otherwise) so that the end users will have difficulty just reinstalling Windows and using the machine as they want, in contradiction to the contract. Ideally, I'd want the machine to die if reinstallation of the OS is attempted. It doesn't have to be completely insurmountable, but it has to be difficult enough to prevent casual reinstallation. Perhaps on bootup the system can check whether certain files exist on the computer and refuse to boot if they do not. I don't know if this is possible, but maybe BIOS is password protected, and searches for files before boot up. The files it looks for could be date sensitive, i.e. require remote replacement on a schedule.

  • Where did System.Design go?

    - by Nilbert
    I am making a C# project in which I am using ScintillaNet, and it says: The referenced assembly "ScintillaNet" could not be resolved because it has a dependency on "System.Design, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" which is not in the currently targeted framework ".NETFramework,Version=v4.0,Profile=Client". Please remove references to assemblies not in the targeted framework or consider retargeting your project. I tried adding a reference to System.Design, but it doesn't exist in my list. Do I need to download it somewhere? I have MS Visual Studio 10.

  • Doubts in System call mechanism in linux

    - by bala1486
    We transit from ring3 to ring0 using 'int' or the new 'syscall/sysenter' instruction. Does that mean that the page tables and other stuffs that needs to be modified for the kernel is automatically done by the 'int' instruction or the interrupt handler for the 'int 0x80' will do the required stuff and jump to the respective system call. Also when returning from a system call, we again need to go to user space. For this we need to know the instruction address in the user space to continue the user application. Where is that address stored. Does the 'ret' instruction automatically changes the ring from ring3 to ring0 or where/how this ring changing mechanism takes place? Then, i read that changing from ring3 to ring0 is not as costly as changing from ring0 to ring3. Why is this so?? Thanks, Bala

  • Measuring execution time of a system call in C++

    - by jm1234567890
    I have found some code on measuring execution time here http://www.dreamincode.net/forums/index.php?showtopic=24685 However, it does not seem to work for system calls. I imagine this is because the execution jumps out of the current process. clock_t begin=clock(); system(something); clock_t end=clock(); cout<<"Execution time: "<<diffclock(end,begin)<<" s."<<endl; Then double diffclock(clock_t clock1,clock_t clock2) { double diffticks=clock1-clock2; double diffms=(diffticks)/(CLOCKS_PER_SEC); return diffms; } However this always returns 0 seconds... Is there another method that will work? Also, this is in Linux. Thanks!

  • Call iconv from Ruby through system()

    I have a problem with iconv tool. I try to call it from rake file in that way: Dir.glob("*.txt") do |file| system("iconv -f UTF-8 -t 'ASCII//TRANSLIT' #{ file } >> ascii_#{ file }") end But one file is converted partly (size of partialy converted: 10059092 bytes, before convertion: 10081854). Comparing this two files prove that not all content was writen to ASCII. When I call this command explicit from shell it works perfectly. Other smaller files are converted without problems. Is there any limitations on iconv or Ruby's system()?

    Hi there, I'm trying to use the PHP exec() or system() (or any other similar function) to run a batch file, but I can't seem to get these to return anything. The simplest example I've seen is this, which outputs nothing: <?php echo system('dir'); ?> The script is running on a windows XP machine on IIS with PHP installed and I've also tried it on my shared hosting account running windows 2003 server/IIS. Can anyone suggest what I need to do to get this working, or provide any commands I can use for troubleshooting? Cheers, Tom

  • How to detect pending system shutdown on Linux?

    - by Rajorshi
    Hi, I am working on an app where I need to detect system shutdown. However, I have not found any reliable way get a notification on this event. I know that on shutdown, my app will receive a SIGTERM signal followed by a SIGKILL. What I want to know is if there is someway to query if a SIGTERM is part of a shutdown sequence? Does any one know if there is a way to query that programmatically (C API)? As far as I know, the system does not provide any other method to query for an impending shutdowm. If it does, that would solve my problem as well. I have been trying out runlevels as well, but change in runlevels seem to be instantaneous and without any prior warnings.

  • Issuing native system commands in Scala

    - by Tony
    I want to issue a native system command from a Scala program, and perhaps trap the output. ("ls" comes to mind. There may be other ways to get directory information without issuing the command, but that's beside the point of my question.) It would correspond to os.system(...) in Python. I've looked in "Programming in Scala". I've looked in O'Reilly's "Programming Scala". I've Googled several combinations of terms. No luck yet. Can someone out there give me an example, or point me at a resource where I can find an example?

  • Killing a script launched in a Process via os.system()

    - by L.J.
    I have a python script which launches several processes. Each process basically just calls a shell script: from multiprocessing import Process import os import logging def thread_method(n = 4): global logger command = "~/Scripts/run.sh " + str(n) + " >> /var/log/mylog.log" if (debug): logger.debug(command) os.system(command) I launch several of these threads, which are meant to run in the background. I want to have a timeout on these threads, such that if it exceeds the timeout, they are killed: t = [] for x in range(10): try: t.append(Process(target=thread_method, args=(x,) ) ) t[-1].start() except Exception as e: logger.error("Error: unable to start thread") logger.error("Error message: " + str(e)) logger.info("Waiting up to 60 seconds to allow threads to finish") t[0].join(60) for n in range(len(t)): if t[n].is_alive(): logger.info(str(n) + " is still alive after 60 seconds, forcibly terminating") t[n].terminate() The problem is that calling terminate() on the process threads isn't killing the launched run.sh script - it continues running in the background until I either force kill it from the command line, or it finishes internally. Is there a way to have terminate also kill the subshell created by os.system()?

  • System.Net.WebClient Class in .Net CompactFramework 3.5 ?

    - by Leen15
    Hi at all! I need to comunicate with a Server that give me async answers (streamer connection). I find this: http://msdn.microsoft.com/en-en/library/ms144211%28v=VS.80%29.aspx that generate this event: http://msdn.microsoft.com/en-en/library/system.net.webclient.openreadcompleted%28v=VS.80%29.aspx I think this is what i need, but i don't have the WebClient class in my System.Net of CompactFramework 3.5. How can i do? Thanks. EDIT: I've done a more clear question: httpRequest, httpResponse, send GET through Stream and Receive the Result in C#

  • pthreads recursively calling system command and segfault appears

    - by jess
    I have a code base where i am creating 8 threads and each thread just calls system command to display date in a continuous cycle, as shown below: void * system_thread(void *arg) { int cpu = (int)arg; printf("thread : start %d\n", cpu); for (;;) { // date ã³ãã³ãã®å®è¡ if (mode == 0) { system("date"); } else { f_hfp_nlc_Fsystem("date"); } } sleep(timerval); return NULL; } This application segfaults after running for 2-3 seconds, due to following 2 reasons: 1. read access, where the address is out of VM area 2. write acces, where it does not of write permission and its trying to modify some structure.
