What Is A Socket Error
them; it only takes a minute: Sign up bind() fails with windows socket error 10049 up vote 1 down vote favorite I try to make a client/server program in C with IPv6 and UDP. When the program binds the wsaeaddrnotavail socket it return the WSAError 10049. I know that this is a problem with the adress name but don't see whats the problem. I hope someone can help. struct sockaddr_in6 server, client; SOCKET sock; char buffer[BUFFERSIZE]; LPTSTR recvBuff[1024]; DWORD recvBuffLen = 1024UL; int len = sizeof(client); WORD wVersionRequested; WSADATA wsaData; wVersionRequested = MAKEWORD(1,1); WSAStartup(wVersionRequested, &wsaData); sock = socket(AF_INET6, SOCK_DGRAM, 0); if (sock < 0) error("Fehler beim Anlegen des Sockets"); server.sin6_family = AF_INET6; server.sin6_port = htons(6000); server.sin6_addr = in6addr_any; wsagetlasterror 0 if (bind(sock, (struct sockaddr *) &server, sizeof(server)) == -1) error("Fehler beim binden des Sockets"); c windows sockets bind share|improve this question asked Jan 16 '13 at 19:18 Markus Wilhelm 29124 What's PORT ? –Bart Friederichs Jan 16 '13 at 19:21 yeah it is defined, i changed the code to the real value –Markus Wilhelm Jan 16 '13 at 19:23 According to many Linux tutorials, you have to memset the sockaddr_in6 with zeroes. (I know it's Windows, but worth a shot) –Bart Friederichs Jan 16 '13 at 19:24 thanks now it works –Markus Wilhelm Jan 16 '13 at 19:43 add a comment| 3 Answers 3 active oldest votes up vote 2 down vote accepted This normally results from an attempt to bind to an address that is not valid for the local computer.. You should use PF_INET here instead of AF_INET. They have the same value, but you're not specifying an address family AF here, you're specifying a protocol family PF. This is just a style recommendation. I would suggest to memset zero the below arrays,structures: struct sockaddr_in6 server, client; SOCKET sock; char buffer[BUFFERSIZE]; LPTSTR recvBuff[1024]; share|improve this answer edited Sep 5 at 10:44 EJP 196k17140247 answered Jan 16 '13 at 19:49 askmish 4,4511136 add a comment| up vote 3 down vote Before you can use the sockaddr_in6 struct, you will have to memset it to zero:

My reply to your other message was as follows: The documentation on this error says that an invalid IP address was provided in the Bind() command. Are you waiting long enough for the NIC to receive a new address from the DHCP server? If you are unsure, or not using a delay, I would suggest pausing for up to 30 seconds to allow the NIC time to aquire a new address. Let me know how it works out for you.

leads to early laziness" syndrome.Without further a do - a lovely issue I had to face.On certain machines - http://aprogrammers.blogspot.com/2009/08/winsock-error-10049-with-no-apparent.html 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 returned a last error code 10049 http://serverfault.com/questions/314083/what-does-it-mean-for-an-address-to-be-invalid-in-context-error-code-os-10049 (0x2741) which means "The requested address is not valid in its context". This usually happens when someone tries to use a non-existent local IP address as the socket address, socket error 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. I found no mention of this behavior anywhere on-line. I disabled the Windows bind 10049 error 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 192.168.2.110:55301...+++ Success!!!Testing bind() TCP with 0.0.0.0:0...+++ Success!!!Testing bind() TCP with 0.0.0.0:1024...+++ Success!!!Testing bind() TCP with 0.0.0.0:32033...+++ Success!!!Testing bind() TCP with 0.0.0.0:55301...+++ Success!!!Testing bind() TCP with 192.168.2.110:0...+++

I made one small change because I want Apache to serve a single XML file separately from everything else it does, purely for testing on my local machine. The change is that I inserted this into httpd.conf: # Based on http://httpd.apache.org/docs/2.2/vhosts/examples.html Listen 10.11.12.13:85 NameVirtualHost 10.11.12.13:85
