  • how can i fix this problem with mount volume in ubuntu 10.10?

    - by Ali Unlu
    I have two operating system: ubuntu 10.10 and windows 7 ultimate. I trisected my HDD.One of these is for main Windows files,one of this for ubuntu system and the last drive which must be accessible on both of two system is for common files (musics, films, etc). This last partition is J: in Windows. Unfortunately when I was setting up ubuntu 10.10 while disk partition, I forgot mount my J drive as /windows and accidentally mounted it as swap . Then, I tried to do this visible in ubuntu.But I couldn't myself. Device : /dev/sda4 and whenever I try to do this I always get this error : Error mounting: mount exited with exit code 1: helper failed with: mount: according to mtab, none is already mounted on none mount failed

The server DNS are ns1 and ns2 of the first domain. Second domain is on the shared IP and first domain has a dedicated IP. I cant resolve the problem :( and appreciate any help so much!

  • Setting up a web developer lab for learning purposes

    - by Saleh Al-Abbas
    I'm not a developer by profession. Therefore, I'm not exposed to real world technical problems that face professional developers. I read/heard about web farms, integration between different systems, load balancing ... etc. Therefore, I was wondering if there are ways for the individual developer to create an environment that simulates real world situations with minimal number of machines like: web farms & caching simulating many users accessing your website (Pressure tests?) Performance load balancing anything you think I should consider. By the way, I have a server machine and 1 PC. and I don't mind investing in tools and software. PS. I'm using Microsoft technologies for development but I hope this is not a limiting factor. Thanks

  • difference between calling javascript function on body load or directly from script.

    - by Abbas
    i am using a javascript where in i am creating multiple div (say 5) at runtime, using javascript function, all the divs contain some text, which is again set at runtime, now i want to disable all the divs at runtime and have the page numbers in the bottom, so that whenever user clicks on the page number only that div should get visible else other should get disable, i have created a function, which accepts parameter, as page number, i enable the div whose page number is clicked and using a for loop, i disable all the other divs, now here my problem is i have created two functions, 1st (for adding divs and disabling all the divs except 1st) and writing content to it, and other for enabling the div whose page number is clicked, and i have called the Adding div function on body onload; now first time when i run, page everthing goes well, but next time when i click on any of the page number, it just gets enabled and again that AddDiv function, runs and re-enables all the divs.. Please reply why this is happening and how should i resolve my issue... Below is my script, content for the div are coming using Json. <body onload="JsonScript();"> <script language="javascript" type="text/javascript"> function JsonScript() { var existingDiv = document.getElementById("form1"); var newAnchorDiv = document.createElement("div"); newAnchorDiv.id = "anchorDiv"; var list = { "Article": articleList }; for(var i=0; i < list.Article.length; i++) { var newDiv = document.createElement("div"); newDiv.id = "div"+(i+1); newDiv.innerHTML = list.Article[i].toString(); newAnchorDiv.innerHTML += "<a href='' onclick='displayMessage("+(i+1)+")'>"+(i+1)+"</a>&nbsp;"; existingDiv.appendChild(newDiv); existingDiv.appendChild(newAnchorDiv); } for(var j = 2; j < list.Article.length + 1; j ++) { var getDivs = document.getElementById("div"+j); getDivs.style.display = "none"; } } function displayMessage(currentId) { var list = {"Article" : articleList} document.getElementById("div"+currentId).style.display = 'block'; for(var i = 1; i < list.Article.length + 1; i++) { if (i != currentId) { document.getElementById("div"+i).style.display = 'none'; } } } </script> Thanks and Regards

  • Running multiple environments on one AWS EC2 instance (Elastic Beanstalk)

    - by Abbas
    I am very new to the Amazon AWS services. I was wondering if there is a way to run an instance of EC2 (say, Amazon Linux AMI) and then connect two environments to this instance. Particularly, I'd like to run a PHP and a Tomcat environment on a single EC2 instance. The problem is, every time I create a new environment in Elastic Beanstalk, it seems to create a new EC2 instance as well. Am I missing something here? I'd appreciate any hint on this.

  • Django QuerySet API: How do I join iexact and icontains?

    - by Zeynel
    Hello, I have this join: lawyers = Lawyer.objects.filter(last__iexact=last_name).filter(first__icontains=first_name) This is the site If you try Last Name: Abbas and First Name: Amr it tells you that amr abbas has 1 schoolmates. But if you try First name only it says that there are no lawyers in the database called amr (obviously there is). If I change (last__iexact=last_name) to (last__icontains=last_name) then leaving Last Name blank works fine and amr is found. But with last__icontains=last_name if you search for "collin" you also get "collins" and "collingwood" which is not what I want. Do you know how I can use iexact and also have it ignored if it is blank? Thanks This is the view function: def search_form(request): if request.method == 'POST': search_form = SearchForm(request.POST) if search_form.is_valid(): last_name = search_form.cleaned_data['last_name'] first_name = search_form.cleaned_data['first_name'] lawyers = Lawyer.objects.filter(last__iexact=last_name).filter(first__icontains=first_name) if len(lawyers)==0: form = SearchForm() return render_to_response('not_in_database.html', {'last': last_name, 'first': first_name, 'form': form}) if len(lawyers)>1: form = SearchForm(initial={'last_name': last_name}) return render_to_response('more_than_1_match.html', {'lawyers': lawyers, 'last': last_name, 'first': first_name, 'form': form}) q_school = Lawyer.objects.filter(last__icontains=last_name).filter(first__icontains=first_name).values_list('school', flat=True) q_year = Lawyer.objects.filter(last__icontains=last_name).filter(first__icontains=first_name).values_list('year_graduated', flat=True) lawyers1 = Lawyer.objects.filter(school__iexact=q_school[0]).filter(year_graduated__icontains=q_year[0]).exclude(last__icontains=last_name) form = SearchForm() return render_to_response('search_results.html', {'lawyers': lawyers1, 'last': last_name, 'first': first_name, 'form': form}) else: form = SearchForm() return render_to_response('search_form.html', {'form': form, })

  • Android source code not working, reading frame buffer through glReadPixels

    - by Muhammad Ali Rajput
    Hi, I am new to Android development and have an assignment to read frame buffer data after a specified interval of time. I have come up with the following code: public class mainActivity extends Activity { Bitmap mSavedBM; private EGL10 egl; private EGLDisplay display; private EGLConfig config; private EGLSurface surface; private EGLContext eglContext; private GL11 gl; protected int width, height; //Called when the activity is first created. @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // get the screen width and height DisplayMetrics dm = new DisplayMetrics(); getWindowManager().getDefaultDisplay().getMetrics(dm); int screenWidth = dm.widthPixels; int screenHeight = dm.heightPixels; String SCREENSHOT_DIR = "/screenshots"; initGLFr(); //GlView initialized. savePixels( 0, 10, screenWidth, screenHeight, gl); //this gets the screen to the mSavedBM. saveBitmap(mSavedBM, SCREENSHOT_DIR, "capturedImage"); //Now we need to save the bitmap (the screen capture) to some location. setContentView(R.layout.main); //This displays the content on the screen } private void initGLFr() { egl = (EGL10) EGLContext.getEGL(); display = egl.eglGetDisplay(EGL10.EGL_DEFAULT_DISPLAY); int[] ver = new int[2]; egl.eglInitialize(display, ver); int[] configSpec = {EGL10.EGL_NONE}; EGLConfig[] configOut = new EGLConfig[1]; int[] nConfig = new int[1]; egl.eglChooseConfig(display, configSpec, configOut, 1, nConfig); config = configOut[0]; eglContext = egl.eglCreateContext(display, config, EGL10.EGL_NO_CONTEXT, null); surface = egl.eglCreateWindowSurface(display, config, SurfaceHolder.SURFACE_TYPE_GPU, null); egl.eglMakeCurrent(display, surface, surface, eglContext); gl = (GL11) eglContext.getGL(); } public void savePixels(int x, int y, int w, int h, GL10 gl) { if (gl == null) return; synchronized (this) { if (mSavedBM != null) { mSavedBM.recycle(); mSavedBM = null; } } int b[] = new int[w * (y + h)]; int bt[] = new int[w * h]; IntBuffer ib = IntBuffer.wrap(b); ib.position(0); gl.glReadPixels(x, 0, w, y + h, GL10.GL_RGBA,GL10.GL_UNSIGNED_BYTE,ib); for (int i = 0, k = 0; i < h; i++, k++) { //OpenGLbitmap is incompatible with Android bitmap //and so, some corrections need to be done. for (int j = 0; j < w; j++) { int pix = b[i * w + j]; int pb = (pix >> 16) & 0xff; int pr = (pix << 16) & 0x00ff0000; int pix1 = (pix & 0xff00ff00) | pr | pb; bt[(h - k - 1) * w + j] = pix1; } } Bitmap sb = Bitmap.createBitmap(bt, w, h, Bitmap.Config.ARGB_8888); synchronized (this) { mSavedBM = sb; } } static String saveBitmap(Bitmap bitmap, String dir, String baseName) { try { File sdcard = Environment.getExternalStorageDirectory(); File pictureDir = new File(sdcard, dir); pictureDir.mkdirs(); File f = null; for (int i = 1; i < 200; ++i) { String name = baseName + i + ".png"; f = new File(pictureDir, name); if (!f.exists()) { break; } } if (!f.exists()) { String name = f.getAbsolutePath(); FileOutputStream fos = new FileOutputStream(name); bitmap.compress(Bitmap.CompressFormat.PNG, 100, fos); fos.flush(); fos.close(); return name; } } catch (Exception e) { } finally { //if (fos != null) { // fos.close(); // } } return null; } } Also, if some one can direct me to better way to read the framebuffer it would be great. I am using Android 2.2 and virtual device of API level 8. I have gone through many previous discussions and have found that we can not know read frame buffer directly throuh the "/dev/graphics/fb0". Thanks, Muhammad Ali

  • iptables DNS resolution

I've installed snort 2.9.2.2, applied the snortsam-2.9.2.2.diff.gz patch and installed snortsam 2.70 on the routermachine In snort.conf besides altering some RULE_PATH I believe I've only added the following line to the file. output alert_fwsam: 127.0.0.1:898/password After doing this two comands: ifconfig p8p1 promisc /usr/local/snort/bin/snort -v -i p8p1 If I ping from the external network to the router IP, I can see the info about the pings.

  • Ubuntu Server - Power failure leads to boot failure

    - by Ali Nadalizadeh
    I have installed Ubuntu Server 10.04.1 LTS on an ext4 partition. Whenever my system looses power suddenly, It doesn't boot into the normal procedure to fix the problems automatically, but switches to the busy box shell (where it says Kernel Panic : No init found) So I guess kernel is refusing to mount the filesystem when it is not clean, since when I boot up using a Live CD and fsck it, it boots up correctly. How can I force kernel to mount the filesystem, even if it is not clean ?, so that automated fsck on system startup fixes the problems... (or it's a grub problem ?) K-V : 2.6.32-26-generic-pae #48-Ubuntu SMP

  • Server can't set IP after power outage

    - by Ali
    The power went out all of a sudden and when we tried to restart everything when it came back on - our server can't be assigned an IP? We got an error stating that the IP for the server was already in use by another system. We then shut down all systems and restarted the server but then for some reason the server was assigned an IP but no one could connect to it - after restarting the server after setting it to have a dynamically assigned ip - the server now has no ip - just 0.0.0.0 - running an ipconfig/renew or ipconfig /release has no effect.. what should we do!!

  • How to interpret output from Linux 'top' command?

    - by Ali
    Following a discussion made HERE about how PHP-FPM consuming memory, I just found a problem in reading the memory in top command. Here is a screenshot of my top just after restarting PHP-FPM. Everything is normal: about 20 PHP-FPM processes, each consuming 5.5MB memory (0.3% of total). Here is the aged server right before restart of PHP-FPM (one day after the previous restart). Here, we still have about 25 PHP-FPM with double memory usage (10MB indicating 0.5% of total). Thus, the total memory used should be 600-700 MB. Then, why 1.6GB memory has been used?

  • Auto-detect proxy settings on network

    - by Ali Lown
    I am having problems trying to run web browser software on the local network through the proxy. When running off the profile drive which is on a network share, the system is unable to auto-detect proxy settings. When running off the local C drive, the browsers are able to correctly autodetect the settings. The error from the browser is about it being unable to fetch the proxy configuration file. Is this some form of authentication preventing it retreiving the settings when running of the network location? PS. Would this be better off on superuser?
