  • What should I encrypt in Debian during install?

    - by ianfuture
    I have seen various guides and recommendations on web about how best to do this but nothing that clearly explains the best way and why. So I understand there is a need for part of Debian during install to be un-encrypted on its own partition to allow it to boot. Most info I have seen is call this /boot and set the boot flag. Next I believe the best approach is to create another partition out of all the rest of the disk space, encrypt this, then on top of that create a LVM and then within the LVM create my various partitions , name them , select size, and file system type. Can I include /swap in the encrypted LVM part ? Is this approach sound? If so what are the partitions I should use (this is going to be a minimal server install with a view to install as and when what I need for a dev server)? Finally how does the installer know what to put in each partition I define ? I appreciate there are more than one question but any help and suggestions would be appreciated. If further clarification is needed please mention in the comments . EDIT : 16/3/2010 After Richard Holloways reply I thought it relevant to add this info: The reasons why I want to do this are to explore maximising security on any server install and set up, due to interest in the area of Computer Security and Forensics. Also I am trying to peform the task as if it being performed in an enterprise situation. On a technical matter, once set up and configured with minimal packages and ssh this server will not physically be easy to access so I will only be entering via ssh. (Yes I know why encrypt something no one will ever be able to get their hands on? Because I can and I want to is the simple answer, but see above too).

  • cset shield --kthread on: should I use this?

    - by lori
    I'm reading up on cpu shielding using Alex Tsariounov's cset utility here: https://rt.wiki.kernel.org/index.php/Cpuset_Management_Utility/tutorial In the tutorial I'm finding the wording around migrating kernel threads from having access to all cpus to running only in a certain cpuset a bit ambiguous The tutorial says the following: Some kernel threads can be moved into the unshielded system cpuset as well. These are the threads that are not bound to specific CPUs. If a kernel thread is bound to a specific CPU, then it is generally not a good idea to move that thread to the system set because at worst it may hang the system and at best it will slow the system down significantly. These threads are usually the IRQ threads on a real time Linux kernel, for example, and you may want to not move these kernel threads into system. If you leave them in the root cpuset, then they will have access to all CPUs. The tutorial then goes on to say: However, if your application demands an even "quieter" shield, then you can move all movable kernel threads into the unshielded system set with the following command. [zuul:cpuset-trunk]# cset shield -k on cset: --> activating kthread shielding cset: kthread shield activated, moving 70 tasks into system cpuset... [==================================================]% cset: done I am confused by this final sentence. By using the word however, it seems to suggest that you typically should not move the movable kernel threads into the unshielded system set. Is this the case, or is it safe to move kernel threads which can be moved into a cpuset, thereby preventing them from running on some cpus?

  • mysql update unique index

    Is there a way to say UPDATE items SET qty=10 WHERE **unique key** instead of saying UPDATE items SET qty=10 WHERE userID=1 AND listID=10 and itemID=100 on the following table? CREATE TABLE IF NOT EXISTS `items` ( `userID` int(20) NOT NULL, `listID` int(20) NOT NULL, `itemID` int(20) NOT NULL, `qty` int(10) NOT NULL, UNIQUE KEY `unique` (`userID`,`listID`,`itemID`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;

  • Image animation problem in silverlight

    - by Jak
    Hi followed " http://www.switchonthecode.com/tutorials/silverlight-3-tutorial-planeprojection-and-perspective-3d#comment-4688 ".. the animation is working fine. I am new to silver light. when i use dynamic image from xml instead of static image as in tutorial,.. it is not working fine, please help me on this. i used list box.. for this animation effect do i need to change listbox to some other arrangement ? if your answer yes means, pls give me some sample code. Thanks in advance. Xaml code: <ListBox Name="listBox1"> <ListBox.ItemTemplate> <DataTemplate> <StackPanel> <Image Source="{Binding imgurl}" HorizontalAlignment="Left" Name="image1" Stretch="Fill" VerticalAlignment="Top" MouseLeftButtonUp="FlipImage" /> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox> My C# code: //getting image URL from xml XElement xmlads = XElement.Parse(e.Result); //i bind the url in to listBox listBox1.ItemsSource = from ads in xmlads.Descendants("ad") select new zestItem { imgurl = ads.Element("picture").Value }; public class zestItem { public string imgurl { get; set; } } private int _zIndex = 10; private void FlipImage(object sender, MouseButtonEventArgs e) { Image image = sender as Image; // Make sure the image is on top of all other images. image.SetValue(Canvas.ZIndexProperty, _zIndex++); // Create the storyboard. Storyboard flip = new Storyboard(); // Create animation and set the duration to 1 second. DoubleAnimation animation = new DoubleAnimation() { Duration = new TimeSpan(0, 0, 1) }; // Add the animation to the storyboard. flip.Children.Add(animation); // Create a projection for the image if it doesn't have one. if (image.Projection == null) { // Set the center of rotation to -0.01, which will put a little space // between the images when they're flipped. image.Projection = new PlaneProjection() { CenterOfRotationX = -0.01 }; } PlaneProjection projection = image.Projection as PlaneProjection; // Set the from and to properties based on the current flip direction of // the image. if (projection.RotationY == 0) { animation.To = 180; } else { animation.From = 180; animation.To = 0; } // Tell the animation to animation the image's PlaneProjection object. Storyboard.SetTarget(animation, projection); // Tell the animation to animation the RotationYProperty.

  • How to create a database deadlock using jdbc and JUNIT

    - by Isawpalmetto
    I am trying to create a database deadlock and I am using JUnit. I have two concurrent tests running which are both updating the same row in a table over and over again in a loop. My idea is that you update say row A in Table A and then row B in Table B over and over again in one test. Then at the same time you update row B table B and then row A Table A over and over again. From my understanding this should eventually result in a deadlock. Here is the code For the first test. public static void testEditCC() { try{ int rows = 0; int counter = 0; int large=10000000; Connection c=DataBase.getConnection(); while(counter<large) { int pid = 87855; int cCode = 655; String newCountry="Egypt"; int bpl = 0; stmt = c.createStatement(); rows = stmt.executeUpdate("UPDATE main " + //create lock on main table "SET BPL="+cCode+ "WHERE ID="+pid); rows = stmt.executeUpdate("UPDATE BPL SET DESCRIPTION='SomeWhere' WHERE ID=602"); //create lock on bpl table counter++; } assertTrue(rows == 1); //rows = stmt.executeUpdate("Insert into BPL (ID, DESCRIPTION) VALUES ("+cCode+", '"+newCountry+"')"); } catch(SQLException ex) { ex.printStackTrace(); //ex.getMessage(); } } And here is the code for the second test. public static void testEditCC() { try{ int rows = 0; int counter = 0; int large=10000000; Connection c=DataBase.getConnection(); while(counter<large) { int pid = 87855; int cCode = 655; String newCountry="Jordan"; int bpl = 0; stmt = c.createStatement(); //stmt.close(); rows = stmt.executeUpdate("UPDATE BPL SET DESCRIPTION='SomeWhere' WHERE ID=602"); //create lock on bpl table rows = stmt.executeUpdate("UPDATE main " + //create lock on main table "SET BPL="+cCode+ "WHERE ID="+pid); counter++; } assertTrue(rows == 1); //rows = stmt.executeUpdate("Insert into BPL (ID, DESCRIPTION) VALUES ("+cCode+", '"+newCountry+"')"); } catch(SQLException ex) { ex.printStackTrace(); } } I am running these two separate JUnit tests at the same time and am connecting to an apache Derby database that I am running in network mode within Eclipse. Can anyone help me figure out why a deadlock is not occurring? Perhaps I am using JUnit wrong.

  • TFS Check in rules

    - by NPehrsson
    Hi I'm out of setting up an TFS server and I want to set some check-in rules. I for example want to be able to set rules about method lenght, complexity and so on, I found NDepend very convenient can I somehow use NDepend to run some rules on the files trying to check in. I also want to be able to bypass the rules sometimes. Are there any blogs or discussions around this, if it wont work with NDepend are there any other tools or ways I can use?

  • Many Associations Leading to Slow Query

    - by Joey Cadle
    I currently have a database that has a lot of many to many associations. I have services which have many variations which have many staff who can perform the variation who then have details on themselves like name, role, etc... At 10 services with 3 variations each and up to 4 out of 20 staff attached to each service even doing something as getting all variations and the staff associated with them takes 4s. Is there a way I can reduce these queries that take a while to process? I've cut down the queries by doing eager loading in my DBM to reduce the problems that arise from 1+N issues, but still 4s is a long query for just a testing stage. Is there a structure out there that would help make such nested many to many associations much quicker to select? Maybe combining everything past the service level into a single table with a 'TYPE' column ?? I'm just not knowledgable enough to know the solution that turns this 4s query into a 300MS query... Any suggestions would be helpful.

  • C optimization breaks algorithm

    - by Halpo
    I am programming an algorithm that contains 4 nested for loops. The problem is at at each level a pointer is updated. The innermost loop only uses 1 of the pointers. The algorithm does a complicated count. When I include a debugging statement that logs the combination of the indexes and the results of the count I get the correct answer. When the debugging statement is omitted, the count is incorrect. The program is compiled with the -O3 option on gcc. Why would this happen?

  • C# Compiler Directives

    - by pm_2
    I’m looking at some C# code, and have come across the following statement: #if DEBUG // Do something here #else // Do something else #endif I assumed that DEBUG would be a defined somewhere as follows: #define DEBUG But I’m unable to find such a definition, although the code seems to behave as though it were set. Is DEBUG a special case, and if so, how is it set / unset?

  • Dash surrounding text

    - by Brandon Hansen
    Given the above dynamically generated text (meaning that I can't just use an image), I am trying to recreate the design using just html and css selectors. I would like to just use a single h4 with the containing text, but am open to other solutions. I would prefer to not use absolute positioning, but again, if that is the only way, then so be it. I have tried surrounding with span tags, but those are inline elements that don't have an inherent width. The h4 will be nested within a div, though not always of the same class or id. Any ideas or resources to get me started?

    Hey guys recently I have had the 'priveledge' of trying to set up an anti virus scanner to scan file uploads to my VPN server. I just finished trying to set up ClamAV but it slowed my server down to a hault once initiated so I had to kill it. Does anyone have any recommendations to a program that will accomplish my task and can be executed in php (other than clamAv)? Any advice greatly appreciated.

  • How to refresh the textbox text when tabs are Changed in WPF

    - by StonedJesus
    Well in my WPF application I am using Tab Control which has around 5 tabs. The view of each tab is a user control which I add via a tool box. Main Xaml File: <Grid> <TabControl Height="Auto" HorizontalAlignment="Stretch" Margin="0" Name="tabControl1" VerticalAlignment="Stretch" Width="Auto"> <TabItem Header="Device Control" Name="Connect"> <ScrollViewer Height="Auto" Name="scrollViewer1" Width="Auto"> <my:ConnectView Name="connectView1" /> </ScrollViewer> </TabItem> <TabItem Header="I2C"> <ScrollViewer Height="Auto" Name="scrollViewer2" Width="Auto"> <my1:I2CControlView Name="i2CControlView1" /> </ScrollViewer> </TabItem> <TabItem Header="Voltage"> <ScrollViewer Height="Auto" Name="scrollViewer3" Width="Auto"> <my2:VoltageView Name="voltageView1" /> </ScrollViewer> </TabItem> </TabControl> </Grid> If you notice each view ie.e Connect, I2C and Voltage is a user control which has a view, viewmodel and model class :) Each of these views have set of textboxes in their respective xaml files. Connect.xaml: <Grid> <Textbox Text="{Binding Box}", Name="hello" /> // Some more textboxes </Grid> I2c.xaml: <Grid> <Textbox Text="{Binding I2CBox}", Name="helI2c" /> // Some more textboxes </Grid> Voltage.xaml: <Grid> <Textbox Text="{Binding VoltBox}", Name="heVoltllo" /> // Some more textboxes </Grid>** By default I have set the text of these textboxes to some value. Lets say "12" "13" "14" respectively in my view model classes. My main requirement is to set the text of these textboxes present in each user control to get refreshed when I change the tab. Description: Lets say Connect View is displayed: Value of Textbox is 12 and I edit it and change it to 16. Now I click on I2C tab and then I go back to Connect tab, I want the textbox value to get refreshed back to the initial value i.e. 12. To be precise, is their a method called visibilitychanged() which I can write in all my user control classes, where I can set the value of these Ui components whenever tabs are changed? Please help :)

  • Setting up Mac OSX build server for multiple users?

    - by MGA
    Hello, I need to set up a OS X build server (Xcode for iOS development). Now the tricky part is, this server will be used in a university environment and many students will have access to it for different projects. How can I set it up so that each student's project is private to them only, keep the server itself protected from students and enable students to access and build remotely. I am not very familiar with the Mac OS X environment so any help would be greatly appreciated! Thank you

  • Why might my Emacs use spaces instead of tabs?

    - by Fletcher Moore
    I am trying to diagnose this problem. TAB creates 4 spaces instead of a 4 col TAB like I want. But I don't think it should because C-h v indent-tabs-mode on the buffer in question says it is set to t. When I check my keybindings, TAB is set to c-indent-line-or-region. Does this function ignore my tabs-mode?
