Hi forum, I checked the output of winedebug with +winsock option. For me the interested part is: Code: trace:winsock:WSAStartup succeeded trace:winsock:WS_gethostname name 0x32f154, len 256 trace:winsock:WS_gethostname <- 'fusion' trace:winsock:WS_gethostbyname "fusion" ret 0x16e7d0 trace:winsock:WS_socket af=2 type=2 protocol=0 trace:winsock:WSASocketA af=2 type=2 protocol=0 protocol_info=(nil) group=0 flags=0x1 trace:winsock:WSASocketW af=2 type=2 protocol=0 protocol_info=(nil) group=0 flags=0x1 trace:winsock:WSASocketW created 0138 trace:winsock:WSAAsyncSelect 138, hWnd 0x1400be, uMsg 00000373, event 00000003 trace:winsock:WS_setsockopt socket: 0138, level 0xffff, name 0x4, ptr 0x32f3a8, len 4 trace:winsock:WS_bind socket 0138, ptr 0x32f374 { family AF_INET, address 0.0.0.0, port 9871 }, length 16 trace:winsock:WS2_sendto socket 0138, wsabuf 0x32f2f0, nbufs 1, flags 0, to 0x32f354, tolen 16, ovl (nil), func (nil) trace:winsock:WS2_sendto fd=133, options=0 warn:winsock:wsaErrno errno 13, (Permission denied). warn:winsock:WS2_sendto -> ERROR 10013 trace:winsock:WSAStartup verReq=2 trace:winsock:WSAStartup succeeded trace:winsock:WS_gethostname name 0x32ee24, len 256 trace:winsock:WS_gethostname <- 'fusion' trace:winsock:WS_gethostbyname "fusion" ret 0x16e7d0 trace:winsock:DllMain 0x7dcb0000 0x2 (nil) trace:winsock:WSAStartup verReq=2 trace:winsock:WSAStartup succeeded trace:winsock:WS_gethostname name 0x32f2a4, len 256 trace:winsock:WS_gethostname <- 'fusion' trace:winsock:WS_gethostbyname "fusion" ret 0x16e7d0 trace:winsock:DllMain 0x7dcb0000 0x2 (nil) trace:winsock:WS2_recvfrom socket 0138, wsabuf 0x32f25c, nbufs 1, flags 0, from (nil), fromlen -1, ovl (nil), func (nil) trace:winsock:WS2_recvfrom fd=139, options=0 warn:winsock:WS2_recvfrom -> ERROR 10035 If more output is needed, please tell me. I found some stuff about some wrong /etc/hosts, mine is here. The file was generated from ubuntu, but i can modify it by hand if necessary. Code: 127.0.0.1 localhost 127.0.1.1 fusion # The following lines are desirable for IPv6 capable hosts ::1 localhost ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters ff02::3 ip6-allhosts fusion is the name of my linux machine wine is running on.
