  1. The two main categories of debugging tools are sniffers and shims.
  2. Captured packets are sometimes too far removed from the problem source to be immediately helpful. (The reverse can be true, too: knowing the sequence of API calls doesn’t tell you every
  3. 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

The Windows function is indicating a problem with one or more parameters. This error occurs if an application passes an invalid pointer value, or if the length of the buffer is too small. The only way I've been able to reproduce it is to run the following unit test repeatedly on the XP VM repeatedly until it fails: import unittest import urllib2 class DownloadUrlTest(unittest.TestCase): Socket Error 10049 Berkeley description: A socket operation failed because the destination host was down.

WinSock functions: gethostbyaddr(), gethostbyname(), getprotobyname(), getprotobynumber(), getservbyname(), getservbyport(), WSAAsyncGetProtoByName(), WSAAsyncGetProtoByNumber(), WSAAsyncGetServByName(), WSAAsyncGetServByPort(), WSAAsyncGetHostByAddr(), WSAAsyncGetHostByName(), See also: WSAHOST_NOT_FOUND, WSANO_RECOVERY, WSATRY_AGAIN WSANO_RECOVERY (11003) This is a non-recoverable error Berkeley description: This is a Socket Error 10054 BUT WHY?? This error is returned from operations on nonblocking sockets that cannot be completed immediately, for example recv when no data is queued to be read from the socket. The WinSock API does not provide access to the Network File System application protocol, so this error is irrelevant to WinSock.

Other information varies between different errors. Socket Error 10054 Connection Reset By Peer have bounds, or specific values) might return this error. msg124607 - (view) Author: Terry J.

This normally results from an attempt to bind to an address that is not valid for the local computer. Check This Out If you are using a host table exclusively, you'll need to update it to add the destination hostname and address. Some types of shims work in such a way that they don’t require administrator privileges on the local machine, unlike most sniffers. You could use this to verify that you're receiving TCP resets or ICMP Port Unreachable packets each time you attempt to connect. Socket Error 10053
