Windows Socket Error 10049


a TCP reset received from remote host). If not, check with your WinSock vendor to see if they have a newer WinSock available. Alternately, you could call setsockopt(SO_REUSEADDR) to allow duplicate local addresses in a single application, but this is a kludgy approach (i.e. Unlike Berkeley, however, WinSock v1.1 doesn't ascribe this error to any functions. have a peek here

Developers should consider handling the referenced errors similarly. See WSASYSNOTREADY for details. I chose 54321 as the port following an msdn example. WinSock description: Same as Berkeley.

This error occurs if the sin_addr is INADDR_ANY (i.e. It also occurs with functions that take a socket handle and a sockaddr structure as input parameters. The "address" they refer to, typically refers to the local "socket name", which is made up of the 3-tuple: protocol, port-number and IP address.

  1. WinSock description: Same as Berkeley.
  2. Try a "traceroute" to the host you were connected to.
  3. Do a traceroute to try to determine where the failure occurs along the route between your host and the destination host.
  4. WinSock description: No equivalent in WinSock.
  5. WSAEADDRINUSE (10048) Address already in use.
  6. WSAEAFNOSUPPORT (10047) Address family not supported by protocol family.
  7. The values for WSANO_DATA and WSANO_ADDRESS (11004) are duplicates, so we don't count one of them.
  8. The Windows Sockets errors are listed in alphabetical order below (they're cross-referenced in a list in numerical order further below).
  9. Apparently, the Windows Sockets specification left this out by oversight.

In Berkeley, this error also occurs when you are trying to name the local socket (assign local address and port number) with bind(), but Windows Sockets doesn't ascribe this error to WinSock functions: With a datastream socket: connect() and FD_CONNECT WSAAsyncelect() notification message. send() & sendto(): socket not bound (for Dgram) or not yet connected (for Stream) The v1.1 specification also has a detailed description for the connect() function which says: "socket not already Socket Error 11004 Berkeley description: An operation was attempted on something that is not a socket.

binding the server socket to localhost makes it listen on (netstat) => connecting via "" fails, and via localhost fails too... –Incubbus Aug 15 '12 at 18:59 Dude, navigate here WinSock description: Same as Berkeley. If the signal handler performs a normal return, the interrupted function call will seem to have returned the error condition. Esker" mean? Socket Error 10053

Detailed description: setsockopt(): WinSock generates this error if you try to set SO_KEEPALIVE but the connection has already been aborted (e.g. WinSock description: No equivalent. Specifically, the v1.1 Windows Sockets specification notes the domain name system (DNS) errors "FORMERR, REFUSED, and & NOTIMP. Check This Out I seem to be getting the exact same problem!

So there's nothing strange on your code if you call listen and it printfs immediatelly the 'Done' statement, simply add an 'accept' to block your program until a connection request is Winsock Error 10054 Fix Developer suggestions: If you don't detect it beforehand (e.g. No new replies allowed.

The WinSock implementation will not allow you to send after this. Berkeley description: A request to send data was disallowed because the socket had already been shut down with a previous shutdown() call. WinSock functions: Additional functions: If a WinSock implementation has an upper limit to the number of simultaneous tasks it can handle, an application's initial call to WSAStartup() could fail with Transposition of first matrix in crossprod in R Achieve same random number sequence on different OS with same seed Securing a LAN that has multiple exposed external at Cat 6 cable

WinSock functions: connect(), sendto(), FD_CONNECT Additional functions: It seems odd that the v1.1 specification doesn't ascribe this error to the function bind(). I try to bind becouse i'm not actualy writing a program, but learning the principles of network programming, so i might do something wrong, like this one :) Last edited on Berkeley description: A bad option or level was specified in a getsockopt()(2) or setsockopt(2) call. Group list elements using second list "/usr/bin/ping" is shown as yellow-on-red in the default Fedora bash color scheme -- what does it mean?

On a datastream socket, some applications use this error with a non-blocking socket calling connect() to detect when a connection attempt has completed, although this is not recommended since some WinSocks If an application sends a UDP packet to a host/port that does not have a datagram socket "listening," the network system may respond by sending back an ICMP Port Unreachable packet If you have more than one WINSOCK DLL on your system, be sure the first one in the path is appropriate for the network subsystem currently loaded. asked 3 years ago viewed 1054 times active 3 years ago Blog Stack Overflow Podcast #93 - A Very Spolsky Halloween Special Related 2bluetooth winsock error 10049 on connect()0Can Winsock connections

This might help us notify our users as to what actions they must take to unblock our application with their anti-virus "flavor".I hope this post will help others, somewhere, somehow. User suggestions: Check that the WINSOCK.DLL file is in the current path Check that the WINSOCK.DLL file is from the same vendor as your underlying protocol stack. TCP/IP scenario: Calling shutdown() with how=1 or how=2 sends a TCP FIN packet to the remote address, which literally means "I'm done sending."
