Windows 7 Socket Bind Error


The above code will create a socket of : Address Family : AF_INET (this is IP version 4) Type : SOCK_STREAM (this means connection oriented TCP protocol) Protocol : 0 [ but its not possible with the client you programmed in C why!! So, we use TCP sockets for communication with our server components running on various platforms. All rights reserved. http://devstude.net/socket-error/windows-socket-error-value.php

In fact it is a prefered way to do it. I think you may have something else using that port. So we need 2 things , IP address and port number to connect to. Listen for connections After binding a socket to a port the next thing we need to do is listen for connections.

  • So we need to keep our server RUNNING non-stop.
  • Also, making this timeout too short could have negative side-effects, particularly in lossy or congested networks.
  • Solutions?
  • Think of this as a pipe which is not interfered by other data.
  • Then the ip address can be used to make a connection using a socket.
  • This is a problem because most servers bind to the port, but they don't bind to a specific address, instead they use INADDR_ANY (this is why things show up in netstat
  • We shall now use threads to create handlers for each connection the server accepts.
  • Please fill in the above blanks with code.
  • Function gethostbyname is used for this purpose.
  • On Windows Vista and later, the dynamic client port range can be viewed and changed using netsh commands.

Suppose I pick local port 1010, and connect to foobar.com port 300, and then close locally, leaving that port in TIME_WAIT. Read/Send We have already learnt how to open a socket.

Tell the kernel that you are willing to re-use the port anyway: int yes=1; //char yes='1'; // use this under Solaris if (setsockopt(sockfd, SOL_SOCKET, SO_REUSEADDR, &yes, sizeof(yes)) == -1) { perror("setsockopt"); Socket.bind C# The socket is placed in that special state so that packets that were out in the network when you shut it down can be captured and thrown away if they arrive If the client disconnects , the connection handler ends. Strategies for Avoidance SO_REUSEADDR You can use setsockopt() to set the SO_REUSEADDR socket option, which explicitly allows a process to bind to a port which remains in TIME_WAIT (it still only

Here is a code sample : /* Create a TCP socket */ #include #include #pragma comment(lib,"ws2_32.lib") //Winsock Library int main(int argc , char *argv[]) { WSADATA wsa; SOCKET s; printf("\nInitialising Winsock..."); https://forums.techguy.org/threads/solved-c-windows-7-socket-problem.919618/ OK , so we are now connected. Socket Error 10049 The idea here is to let users who used the app and upgraded their OS to win7 continue working without meddling around with some UAC. Listen Msdn After a few tests, every single free port less than 1024 was stuck in TIME_WAIT and I couldn't proceed.
