  • Java, server client TCP communication ends with RST

    - by Senne
    I'm trying to figure out if this is normal. Because without errors, a connection should be terminated by: FIN -> <- ACK <- FIN ACK -> I get this at the end of a TCP connection (over SSL, but i also get it with non-encrypted): From To 1494 server client TCP search-agent > 59185 [PSH, ACK] Seq=25974 Ack=49460 Win=63784 Len=50 1495 client server TCP 59185 > search-agent [ACK] Seq=49460 Ack=26024 Win=63565 Len=0 1496 client server TCP 59185 > search-agent [PSH, ACK] Seq=49460 Ack=26024 Win=63565 Len=23 1497 client server TCP 59185 > search-agent [FIN, ACK] Seq=49483 Ack=26024 Win=63565 Len=0 1498 server client TCP search-agent > 59185 [PSH, ACK] Seq=26024 Ack=49484 Win=63784 Len=23 1499 client server TCP 59185 > search-agent [RST, ACK] Seq=49484 Ack=26047 Win=0 Len=0 The client exits normally and reaches socket.close, shouldn't then the connection be shut down normally, without a reset? I can't find anything about the TCP streams of java on google...

  • How can I pre-authorize authopen?

    - by Georg
    I'm using authopen inside one of my programs to modify files owned by root. As can be seen in the screenshot below authopen asks for a admin password. What I'd like to achieve is that the dialog shows my app's name and then passes the authorization to authopen. Code Launching authopen which returns an authorized file descriptor. int pipe[2]; socketpair(AF_UNIX, SOCK_STREAM, 0, pipe); if (fork() == 0) { // child // close parent's pipe close(pipe[0]); dup2(pipe[1], STDOUT_FILENO); const char *authopenPath = "/usr/libexec/authopen"; execl(authopenPath, authopenPath, "-stdoutpipe", [self.device.devicePath fileSystemRepresentation], NULL); NSLog(@"Fatal error, quitting."); exit(-1); } // parent // close childs's pipe close(pipe[1]); // get file descriptor through sockets I'd really like not to use AuthorizationExecuteWithPrivileges because then I'd have to get more rights than I want to.

  • Dynamics of the using keyword

    - by AngryHacker
    Consider the following code: // module level declaration Socket _client; void ProcessSocket() { _client = GetSocketFromSomewhere(); using (_client) { DoStuff(); // receive and send data Close(); } } void Close() { _client.Close(); _client = null; } Given that that the code calls the Close() method, which closes the _client socket and sets it to null, while still inside the `using' block, what exactly happens behind the scenes? Does the socket really get closed? Are there side effects? P.S. This is using C# 3.0 on the .NET MicroFramework, but I suppose the c#, the language, should function identically. The reason i am asking is that occasionally, very rarely, I run out of sockets (which is a very precious resource on a .NET MF devices).

  • Is TcpClient BeginRead/Send thread safe?

    - by wb
    Using a dotNET TcpClient if I have called an asynchronous BeginRead() on the associated network stream can I still call Write() on that stream on another thread? Or do I have to lock() the TcpClient in the code that is called back from the BeginRead and the code that does the send? Also if I close the TcpClient with: client.GetStream().Close(); client.Close(); Do I have to lock() on the TcpClient as well? Thanks in advance.

  • File Uploads with Turbogears 2

    - by William Chambers
    I've been trying to work out the 'best practices' way to manage file uploads with Turbogears 2 and have thus far not really found any examples. I've figured out a way to actually upload the file, but I'm not sure how reliable it us. Also, what would be a good way to get the uploaded files name? file = request.POST['file'] permanent_file = open(os.path.join(asset_dirname, file.filename.lstrip(os.sep)), 'w') shutil.copyfileobj(file.file, permanent_file) file.file.close() this_file = self.request.params["file"].filename permanent_file.close() So assuming I'm understanding correctly, would something like this avoid the core 'naming' problem? id = UUID. file = request.POST['file'] permanent_file = open(os.path.join(asset_dirname, id.lstrip(os.sep)), 'w') shutil.copyfileobj(file.file, permanent_file) file.file.close() this_file = file.filename permanent_file.close()

  • Query in Datareader

    - by bala
    Hi All, In the below code, using (SqlDataReader dr = com.ExecuteReader(CommandBehavior.CloseConnection)) { while (dr.Read()) { _emailTemplate.EmailContent = dr["EMAILCONTENT"].ToString(); _emailTemplate.From = dr["EMAILFROM"].ToString(); _emailTemplate.Subject = dr["EMAILSUBJECT"].ToString(); } } I understand CommandBehavior.CloseConnection will close the connection object when datareader is closed. In the above code, when we use using with SqlDataReader, will it close the datareader before disposing it? in other other words, if i use using statement do i need to close the datareader manually?

  • Pipe overwrites buffer, don't know how to overcome

    I use a simple pipe. I read with a while, 1 char at a time, I think every time I read a char I overwrite something #include <unistd.h> #include <stdio.h> #include <stdlib.h> #include <sys/wait.h> #include <string.h> int main () { int pipefd[2]; int cpid; char buf[31]; if (pipe(pipefd) == -1) { perror("pipe"); exit(EXIT_FAILURE) } cpid = fork(); if (cpid == -1) P perror("cpid"); exit(EXIT_FAILURE); } if (cpid == 0) { // child reads from pipe close (pipefd[1]); // close unused write end while (read (pipefd[0], &buf, 1)>0); printf ("Server receives: %s", buf); close (pipefd[0])l exit (EXIT_SUCCESS); } else { // parent writes to pipe close (pipefd[0]); // closing unused read end; char buf2[30]; printf("Server transmits: "); scanf ("%s", buf2); write (pipefd[1], buf2, strlen(buf2)+1); close(pipefd[1]); wait(NULL); exit(EXIT_SUCCESS); } return 0; } For example, if I input: "Flowers" it prints F and then ~6 unprintable characters

  • How to pass filename to StandardInput (Process) in C#?

    - by Cosmo
    Hello Guys! I'm using the native windows application spamc.exe (SpamAssassin - sawin32) from command line as follows: C:\SpamAssassin\spamc.exe -R < C:\email.eml Now I'd like to call this process from C#: Process p = new Process(); p.StartInfo.UseShellExecute = false; p.StartInfo.RedirectStandardOutput = true; p.StartInfo.RedirectStandardInput = true; p.StartInfo.FileName = @"C:\SpamAssassin\spamc.exe"; p.StartInfo.Arguments = @"-R"; p.Start(); p.StandardInput.Write(@"C:\email.eml"); p.StandardInput.Close(); Console.Write(p.StandardOutput.ReadToEnd()); p.WaitForExit(); p.Close(); The above code just passes the filename as string to spamc.exe (not the content of the file). However, this one works: Process p = new Process(); p.StartInfo.UseShellExecute = false; p.StartInfo.RedirectStandardOutput = true; p.StartInfo.RedirectStandardInput = true; p.StartInfo.FileName = @"C:\SpamAssassin\spamc.exe"; p.StartInfo.Arguments = @"-R"; p.Start(); StreamReader sr = new StreamReader(@"C:\email.eml"); string msg = sr.ReadToEnd(); sr.Close(); p.StandardInput.Write(msg); p.StandardInput.Close(); Console.Write(p.StandardOutput.ReadToEnd()); p.WaitForExit(); p.Close(); Could someone point me out why it's working if I read the file and pass the content to spamc, but doesn't work if I just pass the filename as I'd do in windows command line?

  • binary file to string

    i'm trying to read a binary file (for example an executable) into a string, then write it back FileStream fs = new FileStream("C:\\tvin.exe", FileMode.Open); BinaryReader br = new BinaryReader(fs); byte[] bin = br.ReadBytes(Convert.ToInt32(fs.Length)); System.Text.Encoding enc = System.Text.Encoding.ASCII; string myString = enc.GetString(bin); fs.Close(); br.Close(); System.Text.ASCIIEncoding encoding = new System.Text.ASCIIEncoding(); byte[] rebin = encoding.GetBytes(myString); FileStream fs2 = new FileStream("C:\\tvout.exe", FileMode.Create); BinaryWriter bw = new BinaryWriter(fs2); bw.Write(rebin); fs2.Close(); bw.Close(); this does not work (the result has exactly the same size in bytes but can't run) if i do bw.Write(bin) the result is ok, but i must save it to a string

  • Cancel Leave Event when closing

    - by DiegoMaK
    I have got a textbox on a form with a method being called from the txPredio_Leave event. My problem is that is the user has focus on the textbox and then close the form by clicking the little X close icon in the top corner or by calling this.ActiveMdiChild.Close(); or by calling private void mnucerrarTodas_Click(object sender, EventArgs e) { foreach (Form form in this.MdiChildren) { form.Close(); } } The txPredio leave execute the method.. then i need doesn't excute this method when the form is closing. i have think that one solution could be ask in leave event if form is closing private void txPredio_Leave(object sender, EventArgs e) { if(!form is closing)//pseudo code Check_Load_Predio(); } or other solution could be private void MainForm_FormClosing(object sender, FormClosingEventArgs e) { //code for cancel the txPredio_Leave event } Solution Here Doesn´t work for me. Then I need one solution for my problem. Thanks in advance

  • .Net opening and closing database connections

    - by Dan
    I designed the data access portion of our framework so that every time a business object needs to interact with the database it would have to open a connection, invoke the data access layer (to execute the query), and then close the connection. Then if it needed to run in a transaction it would open the connection, begin the transaction, invoke the data access layer (to execute the query) and then commit the transaction, close the transaction, and finally close the connection. I did it this way with the mindset of open late and close early... but what if I needed to call other BO's to submit data in a single transaction? Is there a better way to handle opening and closing connections as well as working with transactions? I'm a rookie in designing application architecture so I hope I'm not doing this wrongly... any help is appreciated.

  • Can't get my head arround background workers in c#

    I have wrote an application that syncs two folders together. The problem with the program is that it stops responding whilst copying files.

  • Android app unexpectedly quitted when I closed the bluetooth serversocket or bluetooth socket

    - by Lewisou
    The android app quitted without any warning and error when bluetoothServersocket.close() called in the main thread while bluetoothServersocket.accept(); was blocked for incoming connections in another thread. Here is pieces of my code. public void run() { try { bluetoothServerSocket = BluetoothAdapter. getDefaultAdapter().listenUsingRfcommWithServiceRecord(LISTEN_NAME, LISTEN_UUID); /* the thread blocked here for incoming connections */ bluetoothSocket = bluetoothServerSocket.accept(); ... } catch(Exception e) {} finally { try {bluetoothServerSocket.close();} catch(Exception ex) {} try {bluetoothSocket.close();} catch(Exception ex) {} } } And in the activity. public void onStop () { try{thread.bluetoothSocket.close();} catch(Exception ex) {} try{thread.bluetoothServerSocket.close();} catch(Exception ex) {} super.onStop(); } When I clicked the back button. The activity closed but after about one second the app quitted without any warning. My android os version is 2.2. a HTC Desire device.

  • Slide down and slide up div on click

    - by 422
    I am using the following code to open and close a div ( slide up/down ) using js I have the slide down event attached to a button and the slide up event sttached to close text. What I want is the button onclick to open and onclick again close the slide element. Here is the JS // slide down effect $(function(){ $('.grabPromo').click(function(){ var parent = $(this).parents('.promo'); $(parent).find('.slideDown').slideDown(); }); $('.closeSlide').click(function(){ var parent = $(this).parents('.promo'); $(parent).find('.slideDown').slideUp(); }); }); The HTML: <span class="grabPromo">Open</span> and in the slide down area i have <a class="closeSlide">Close</a> Any help appreciated. Ideally I want a down pointing arrow on the slide down button and a up pointing arrow to replace it to slide up on same button. And do away with the close link altogether. Any help appreciated. Cheers

  • How can I distinguish between overlapping segments of text using HTML?

    - by Siracuse
    Easy question, it is valid to have overlapping spans in html? Example: <span id="1">This is <span id="2"> some text </span> some other text </span> ^ ^ End1 End2 Edit: I see now that the spans closing tag would be ambiguous about which one it is closing, and that first </span> would close span id = 2, not 1 like I intended. My problem is, I have a block of text which I'm trying to highlight based on what the mouse hovers over. This block of text is composed of sections, some of which "overlap" eachother. I'm trying to use some jQuery and HTML to present this document so when I hover over the sections, the appropriate one will be highlighted. So, in my example above, the first span is meant to be ended with the first span close tag, and the second span is meant to be ended to with the second span close tag. This is because of the semantics of my document, these are two overlapping segments. I want it so when I hover to the left, it will only highlight up to span id = 1 and the first span close, if I hover between the two "overlapping" spans, it will highlight both of them, and if I hover to the right, it will highlight from span id=2 to the last span close. However, I'm starting to think this isn't possible. Is there any way I can distinguish segments of text in HTML that allows overlapping? So my jQuery script that highlights when I hover over different spans will highlight the correct portions. Should I alternate between div's and spans? Would that disambiguate what I'm closing then and allow me the do the proper highlighting with my jQuery hover script? I'm wondering about more than 2 segments overlapping now. Sigh, I wish I could just be explicate about what I'm closing.

  • Why is this not a bug in qmail?

    - by jemfinch
    I was reading DJB's "Some thoughts on security after ten years of Qmail 1.0" and he listed this function for moving a file descriptor: int fd_move(to,from) int to; int from; { if (to == from) return 0; if (fd_copy(to,from) == -1) return -1; close(from); return 0; } It occurred to me that this code does not check the return value of close, so I read the man page for close(2), and it seems it can fail with EINTR, in which case the appropriate behavior would seem to be to call close again with the same argument. Since this code was written by someone with far more experience than I in both C and UNIX, and additionally has stood unchanged in qmail for over a decade, I assume there must be some nuance that I'm missing that makes this code correct. Can anyone explain that nuance to me?
