What does Winsock Error 10049 mean?
Winsock error 10049 typically occurs when you attempt to create a socket with an address not on this machine. For example if you have MDaemon running on a machine with an IP address of 192.168.0.1 and you attempt to bind MDaemon to 192.168.0.100 you will receive this error message.

When the program binds the socket it return the WSAError 10049. I know that this is a problem with the adress name but don't see whats the problem.

leads to early laziness" syndrome.Without further a do - a lovely issue I had http://aprogrammers.blogspot.com/2009/08/winsock-error-10049-with-no-apparent.html to face.On certain machines - all Vista SP1 machines, we thought - certain outgoing TCP connections to well known HTTP servers (www.google.com, www.facebook.com, www.microsoft.com etc) simply failed.The failure http://www.hardhats.org/cs/broker/docs/winsock.html returned a last error code 10049 (0x2741) which means "The requested address is not valid in its context". This usually happens when someone tries to use a socket error non-existent local IP address as the socket address, or when someone tries to connect to an invalid remote computer.I wrote a test program and reproduced the behavior. I discovered that, oddly, using ADDR_ANY works perfectly - but binding to a specific interface doesn't work.The test program seemed to work everywhere, including Vista SP2 machines. socket error 10054 I found no mention of this behavior anywhere on-line. I disabled the Windows Firewall and the on-board ESET NOD32 3.0 Business anti-virus, and double checked that everything was turned off. It still failed. I was stumped.I posted on alt.programming.winsock asking about this:Hello all,I have been witnessing some very strange behavior of Winsock onWindows Vista SP1, and would like to share my findings to see ifanyone could help me figure out the answer to what's wrong.I've been running a simple program which tests the behavior of Winsockwhen it comes to binding a UDP socket, binding a TCP socket andbinding and then connecting a TCP socket with a wildcard interface anda specific interface.On my Windows XP SP3, running as an administrator, I get the followingresults:----------------------------------------------------------------------------------------Testing bind() UDP with 0.0.0.0:0...+++ Success!!!Testing bind() UDP with 0.0.0.0:1024...+++ Success!!!Testing bind() UDP with 0.0.0.0:32033...+++ Success!!!Testing bind() UDP with 0.0.0.0:55301...+++ Success!!!Testing bind() UDP with 192.168.2.110:0...+++ Success!!!Testing bind() UDP with 192.168.2.110:1024...+++ Success!!!Testing bind() UDP with 192.168.2.110:32033...+++ Success!!!Testing bind() UDP with 192
list of other sites for Winsock information. NOTE: The following list of error/status messages were copied from the Windows Sockets 2 Application Programming Interface document, Revision 2.2.0, May 10, 1996. WSAEACCES (10013) Permission denied. An attempt was made to access a socket in a way forbidden by its access permissions. An example is using a broadcast address for sendto() without broadcast permission being set using setsockopt(SO_BROADCAST). WSAEADDRINUSE (10048) Address already in use. Only one usage of each socket address (protocol/IP address/port) is normally permitted. This error occurs if an application attempts to bind() a socket to an IP address/port that has already been used for an existing socket, or a socket that wasn't closed properly, or one that is still in the process of closing. For server applications that need to bind() multiple sockets to the same port number, consider using setsockopt(SO_REUSEADDR). Client applications usually need not call bind() at all - connect() will choose an unused port automatically. WSAEADDRNOTAVAIL (10049) Cannot assign requested address. The requested address is not valid in its context. Normally results from an attempt to bind() to an address that is not valid for the local machine, or connect()/sendto() an address or port that is not valid for a remote machine (e.g. port 0). WSAEAFNOSUPPORT (10047) Address family not supported by protocol family. An address incompatible with the requested protocol was used. All sockets are created with an associated "address family" (i.e. AF_INET for Internet Protocols) and a generic protocol type (i.e. SOCK_STREAM). This error will be returned if an incorrect protocol is explicitly requested in the socket() call, or if an address of the wrong family is used for a socket, e.g. in sendto(). WSAEALREADY (10037) Operation already in progress. An operation was attempted on a non-blocking socket that already had an operation in progress - i.e. calling connect() a second time on a non-blocking socket that is already connecting, or canceling an asynchronous request (WSAAsyncGetXbyY()) that has already been canceled or completed. WSAECONNABORTED (1005
