  • SSH Advanced Logging

    - by Radek Šimko
    I've installed OpenSUSE on my server and want to set ssh to log every command, which is send to system over it. I've found this in my sshd_config: # Logging # obsoletes QuietMode and FascistLogging #SyslogFacility AUTH #LogLevel INFO I guess that both of those directives has to be uncommented, but I'd like to log every command, not only authorization (login/logout via SSH). I just want to know, if someone breaks into my system, what did he do.

  • extend web server to serve static files

    - by Turtle
    Hello, I want to extend a web server which is only able to handle RPC handling now. The web server is written in C#. It provides a abstract handler function like following: public string owsHandler(string request, string path, string param, OSHttpRequest httpRequest, OSHttpResponse httpResponse) And I wrote following code to handle image files: Bitmap queryImg = new Bitmap(path); System.IO.MemoryStream stream = new System.IO.MemoryStream(); queryImg.Save(stream, System.Drawing.Imaging.ImageFormat.Bmp); queryImg.Dispose(); byte[] byteImage = stream.ToArray(); stream.Dispose(); return Convert.ToBase64String(byteImage); And I test it in the browser, the image is returned but the image dimension info is missed. Shall I add something more to the code? Or is any general way to server static files? I do not want to serve it in a ASP.net server. Thanks

  • Measuring device drivers CPU/IO utilization caused by my program

    - by Lior Kogan
    Sometimes code can utilize device drivers up to the point where the system is unresponsive. Lately I've optimized a WIN32/VC++ code which made the system almost unresponsive. The CPU usage, however, was very low. The reason was 1000's of creations and destruction of GDI objects (pens, brushes, etc.). Once I refactored the code to create all objects only once - the system became responsive again. This leads me to the question: Is there a way to measure CPU/IO usage of device drivers (GPU/disk/etc) for a given program / function / line of code?

  • Linking IronPython to WPF

    - by DonnyD
    I just installed VS2010 and the great new IronPython Tools extension. Currently this extension doesn't yet generate event handlers in code upon double-clicking wpf visual controls. Is there anyone that can provide or point me to an example as to how to code wpf event handlers manually in python. I've had no luck finding any and I am new to visual studio. Upon generating a new ipython wpf project the auto-generated code is: import clr clr.AddReference('PresentationFramework') from System.Windows.Markup import XamlReader from System.Windows import Application from System.IO import FileStream, FileMode app = Application() app.Run(XamlReader.Load(FileStream('WpfApplication7.xaml', FileMode.Open))) and the XAML is: <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="WpfApplication7" Height="300" Width="300"> <Button>Click Me</Button> </Window> Any help would be appreciated.

  • MSSQL Search Proper Names Full Text Index vs LIKE + SOUNDEX

    - by Matthew Talbert
    I have a database of names of people that has (currently) 35 million rows. I need to know what is the best method for quickly searching these names. The current system (not designed by me), simply has the first and last name columns indexed and uses "LIKE" queries with the additional option of using SOUNDEX (though I'm not sure this is actually used much). Performance has always been a problem with this system, and so currently the searches are limited to 200 results (which still takes too long to run). So, I have a few questions: Does full text index work well for proper names? If so, what is the best way to query proper names? (CONTAINS, FREETEXT, etc) Is there some other system (like Lucene.net) that would be better? Just for reference, I'm using Fluent NHibernate for data access, so methods that work will with that will be preferred. I'm using MS SQL 2008 currently.

  • Location of the fonts on the iPhone?

    - by Kyle
    I'm using the FreeType2 library in an iPhone project, and I'm trying to simply load a TTF file from the system, if possible. FT_Library library; FT_Face face; int error; error = FT_Init_FreeType( &library ); if ( error == 0 ) printf("Initialized FreeType2\r\n"); /* Prints */ error = FT_New_Face(library, "/System/Library/Fonts/Helvetica.ttf", 0, &face); if ( error == FT_Err_Cannot_Open_Resource ) printf("Font not found\r\n"); /* Prints */ That error seems to be for file not found. Is /System/Library/Fonts not the location of the fonts? Or, do iPhone apps simply not have any read access at all to that directory. Thanks!

  • Networking: Adding specific route for printer, on Mac Connected to Two Networks

    - by Jordan
    I have a Mac connected to two different networks (wireless en1 and ethernet en0 ). The ethernet network is the preferred (System Preferences-Set Service Order). I'd like to be able to print to a printer on the wireless network side, without having to go to System Preferences and make the wireless network come first in the service order. Is there a way to add a route for a specific printer?

  • WxPython Incompatible With Snow Leopard?

    - by Alex
    Hello all, Recently I upgraded to Snow Leopard, and now I can't run programs built with wxPython. The errors I get are (from Eclipse + PyDev): import wx File "/var/tmp/wxWidgets/wxWidgets-13~231/2.6/DSTROOT/System/Library/Frameworks /Python.framework/Versions/2.6/Extras/lib/ python/wx-2.8-mac-unicode/wx/__init__.py", line 45, in <module> File "/var/tmp/wxWidgets/wxWidgets-13~231/2.6/DSTROOT /System/Library/Frameworks/Python.framework/Versions/2.6/Extras/lib /python/wx-2.8-mac-unicode/wx/_core.py", line 4, in <module> ImportError:/System/Library/Frameworks /Python.framework/Versions/2.6/Extras/lib/python /wx-2.8-mac-unicode/wx/_core_.so: no appropriate 64-bit architecture (see "man python" for running in 32-bit mode) I don't really understand them and would appreciate if you could help me to do so, also, if you do know what's going on, how can I go about fixing them? Maybe this has something to do with the fact that Snow Leopard is 64-bit? Thanks!!

  • Should I worry about the integrity of my linux software RAID5 after a crash or kernel panic?

    I have a dual core Intel i5 Ubuntu Server 10.04 LTS system running kernel 2.6.32-22-server #33-Ubuntu SMP with three 1TB SATA hard drives set up in a RAID5 array using linux md devices. I have read about the RAID5 write hole and am concerned: if my linux system locks up or kernel panics, should I be assume that the integrety of my data has been compromised and restore from backup? How can I know if the data on the RAID5 array is "safe"?

  • Enable access for assistive device programmatically

    - by Dheeraj
    Hi All, I want to enable Access for assistive devices in System Preferences programmatically. But Problem is that my application is not running as root user and i do not want my application to be as root user and also should not ask for any authentication in between. I want to tap all keyboard events globally. I am using CGEventTapCreate() for the same.In the documentation of CGEventTapCreate() API it is mentioned that, Event taps receive key up and key down events if one of the following conditions is true: The current process is running as the root user. Access for assistive devices is enabled. In Mac OS X v10.4 & later, you can enable this feature using System Preferences, Universal Access panel, Keyboard view. I tried manually by checking the Enable Access for assistive devices from System Preference and it gives me expected output. So is there any way to do the same via program without asking for authentication and also application is not running as root user? Thanks, Dheeraj.

    I want to get multiple file by parsing a input file Through Java. The Input file contains many fasta format of thousands of protein sequence and I want to generate raw format(i.e., without any comma semicolon and without any extra symbol like "", "[", "]" etc) of each protein sequence. A fasta sequence starts form "" symbol followed by description of protein and then sequence of protein.

  • C# LINQ Where Predicate Type Arguments

    - by blu
    I have an XElement with values for mock data. I have an expression to query the xml: Expression<Func<XElement, bool>> simpleXmlFunction = b => int.Parse(b.Element("FooId").Value) == 12; used in: var simpleXml = xml.Elements("Foo").Where(simpleXmlFunction).First(); The design time error is: The type arguments for method 'System.Linq.Enumerable.Where(System.Collections.Generic.IEnumerable, System.Func)' cannot be inferred from the usage. Try specifying the type arguments explicitly' The delegate supplied to Where should take in an XElement and return a bool, marking if the item matches the query, I am not sure how to add anything more to the delegate or the where clause to mark the type. Also, the parallel method for the real function against the Entity Framework does not have this issue. What is not correct with the LINQ-to-XML version?

  • Loop doesn't update listboxes until it is done iterating

    - by Justen
    I have a loop that takes file name from a listbox, performs a system() call, then moves that filename to another listbox. Problem is, it doesn't move the filenames over one at a time, but waits until the entire loop is finished and moves them all at once. What would I do to get it to perform how I want it to? the loop: for each( String^% file in filename ) { int x = convert( file ); lbComplete->Items->Add( lbFiles->Items[0] ); // place the completed file lbFiles->Items->Remove( lbFiles->Items[0] ); // in the other listbox } The function convert() that contains the system call: int convert( String^ file ) { std::stringstream ss; std::string dir, fileAddress, fileName, outputDir; ... return system( ss.str().c_str() ); }

  • Upgrade from .NET 2.0 to .NET 3.5 problems

    - by Bashir Magomedov
    I’m trying to upgrade our solution from VS2005 .NET 2.0 to VS2008 .NET 3.5. I converted the solution using VS2008 conversion wizard. All the projects (about 50) remained targeting to .NET Framework 2.0., moreover if I’m changing target framework manually for one of the projects, all referenced dll (i.e. System, System.Core, System.Data, etc. are still pointing to Framework 2.0. The only way to completely change targeting framework I found is to remove these references and refer them again using proper version of framework. Doing it manually is not best choice I think. 50 projects ~ 10 references each ~ 0.5 minutes for changing each reference is about 5 hours to complete. Am I missing something? Are there any other ways of converting full solution from .NET 2.0 to .NET 3.5? Thank you.

  • Build Systems for PHP Web Apps

    - by macinjosh
    I want to start automating more of my web development process so I'm looking for a build system. I write mostly PHP apps on Mac OS X and deploy Linux servers over FTP. A lot of my clients have basic hosting providers so shell access to their servers is typically not available, however remote MySQL access is usually present. Here is what I want to do with a build system: When Building: Lint JavaScript Files Validate CSS Files Validate HTML Files Minify and concatenate JS and CSS files Verify PHP Syntax Set Debug/Production flags When Deploying Checkout latest version from SVN Run build process Upload files to server via FTP Run SQL scripts on remote DB I realize this is a lot of work to automate but I think it would be worth it. So what is the best way to start down this path? Is there a system that can handle builds and deploys, or should I search for separate solutions? What systems would you recommend?

  • Chrome won't start - Windows 7 x64 is complaining about compatibility

    - by WooYek
    Suddenly Chrome browser does not start, my Windows 7 x64 is complaining: The version of this file is not compatible with the version of Windows you’re running. Check your computer’s system information to see whether you need an x86 (32-bit) or x64 (64-bit) version of the program, and then contact the software publisher. Reinstalling did not help. The things that changed and I have noticed are system updates and Java update. Any ideas, what to do to resolve the issue or troubleshoot it?

  • Why do some games randomly turn my screen a random solid color?

    - by Emlena.PhD
    When playing some games my computer will randomly have an error that I cannot fix without turning it off and back on again. The screen changes to one solid color, which varies (off the top of my head I can remember seeing solid green, magenta, etc..) and the sound blares a single tone. The sound sometimes briefly restores and I can still hear the game sounds and even hear and still be heard by people in my Mumble channel, but the screen doesn't right itself so I'm still blind. What's more is this happens in some games but not in others. While the game is actually running, not while I'm still in the menu. However, it does happen if I'm afk or idle but the game world is still rendering. Games where the error occurs: League of Legends World of Warcraft Trine The Sims 2 Dungeon Defenders Safe games: games where it has never occurred: Tribes: Ascend Star Wars: the Old Republic Battlefield 3 So relatively older games cause the problem while newer games do not? I cannot predict when it will happen, it just seems random. However, if it happens and I try playing the same game further after restart it does appear to occur more frequently after the first time. But if I switch to a safe game it doesn't continue happening. Both of my RAM sticks appear fine, flipped position or either one on their own and games still run, computer still boots. I would think over-heating, but then why not all games? ALso, sometimes it happens immediately after I start playing, within seconds of the 3D world booting up. I'm looking to upgrade very soon so I want to figure out what component or software is fubar and replace/repair it. Any suggestions or recommendations of tools would be helpful. Below is some system information. Dxdiag does not detect any problems. Operating System: Windows 7 Home Premium 64-bit (6.1, Build 7601) Service Pack 1 (7601.win7sp1_gdr.120305-1505) System Manufacturer: Gigabyte Technology Co., Ltd.
