bash - Cannot move or delete files even after chown and chmod -

-

I can not move or delete files in my home directory even after chmod And chown .

At first glance it seems that the permissions have been set correctly. 

  user @ f9195084fbf8: ~ $ ls -lah total 32 quadx-xr-x 18 user user 4.0k Oct 8 17:35. Drwxr-xr-x 16 Route root 4.0K Oct 8 04:57 .. -RWXR-XR-X1 user user 220 April 3 2012 .bash_logout -rwxr-xr-x 1 user user 3.5K 3 April 2012 .bashrc drwxr- Xr-x2 User User 4.0K 8 Oct 05:43 .matplotlib drwxr-xr-x 2 User User 4.0K Oct 8 17:19 .pip -rwxr-xr-x 1 User User 675 April 3 2012 .Profile drwxr-xr -x 15 user user 4.0K Oct 8 04:58 .virtualenvs   
 but I can not remove existing files  
  user @ f9195084fbf8: ~ $ Rm .bashrc rm: `.bashrc 'can not be removed: Operation is not allowed   
 so I try to  chown  and  chmod , but it still does not work.    User @ f9195084fbf8: ~ $ Pseudo Chown -r $ USER: $ GROUP User @ f9195084fbf8: ~ $ sudo chmod -R 755 user @ f9195084fbf8: ~ $ rm .bashrc rm: can not delete `.bashrc ': operation is not allowed user @ f9195084fbf8: ~ $ mv .bashrc .virtualenvs / mv: `.bashrc 'can be taken to` .virtualenvs / .bashrc': Operation is not allowed   
 However, I can write and delete the newly created files. Test.txt user @ f9195084fbf8: ~ $ ls test.txt user @ f9195084fbf8: ~ $ rm test.txt    
 
 
 Has any immovable property fixed on file?  
  lsattr.bashrc   
 If so, you can fix it by:  
  chattr - I -a .bashrc   
 Run to view flags, or check.

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i

I am trying to create Java web framework (and learning), and on the basis of 'Code Generator In the process of making the material view of the database in the process of development, I stumbled into a difficulty, which I do not know how to solve it.
