There are a number of possibilities: 1) The padding in the structure was not zeroed. Make sure to call `memset(&sin, 0, sizeof sin)' before filling it in. 2) The sin_len field is not set, or is set incorrectly. Make sure to set `sin.sin_len = sizeof sin' before using it. 3) The sin_port field is set to a value between 1 and 1023, and you are not root. Pick another port. 4) The sin_port and/or sin_addr fields are in the wrong byte order. Make sure that they are in network order. -GAWollman -- Garrett A.
