I'm trying to use Windows sockets to send and receive UDP packets (in C++). It worked well until three days ago, when the program stopped behaving properly. To summarize the situation: When calling WSAPoll() on my socket, it always returns my socket updated with EVERY revents possible (corresponding to every events I gave the pollfd), even if there is no server launched. When calling recvfrom() and no server is launched, it returns SOCKET_ERROR with error code 10054(*). When calling recvfrom() and a server is launched, it works properly - blocks until it receives something. The behavior is the same whether I try to connect to localhost or to a distant host. (*) I investigated this error. In UDP, it means that there is an ICMP problem. ("On a UDP-datagram socket this error indicates a previous send operation resulted in an ICMP Port Unreachable message."). I indeed call sendto() before recvfrom(), so the problem's not here. I tried to put down my firewall to see if it changed anything, but it didn't. I also tried to put down every network flowing through my PC. In this state I managed to get the program to work for a few minutes, but when I enabled the networks it stopped working again. I tried to repeat the process but it would not work anymore. I tried compiling with both visual studio (2015) and MinGW. I tried on another computer too (under Windows 7, mine has Windows 8.1), to no avail. Here is a simple test file which does not work on my computer. #undef _WIN32_WINNT #define _WIN32_WINNT 0x501 #include #include

I used recvfrom() to received a packet from a UDP socket, and it returned -1. By using GetLastError(), I found the error code 100054. Any one recvfrom error 10054 knows what it means? Reply With Quote December 29th, 2002,08:39 PM #2 wuyh View Profile View Forum Posts Member Join Date Dec 2002 Posts 214 100054 not such a system defined error. Are you inquiring the error code 10054? It means the connection is closed forcely by remote host. If you are using VC, you can use a small tool named ErrorLookup to look up the error code. Reply With Quote December 29th, 2002,08:45 PM #3 caperover2002 View Profile View Forum Posts Member Join Date Oct 2002 Posts 359 I am using UDP, which should not be closed by the remote host. I know 100054 it means like that in TCP/IP protocol. BTW,I could not find this error code using Error Lookup.

Its something like connection closed by remote host. Its one of those errors to ignore if I remember correctly Reply With Quote December 30th, 2002,03:01 AM #5 Andreas Masur View Profil
