Regarding the retransmissions ... I'm not trying to change the retransmit interval, but I'm trying to limit the retransmit attempts. For example, if the retransmit interval is 1sec, then the retransmit attempts will occur at 1s, 2s, 4s, 8s, 16s, 32s, 64s, 64s, 64s, 64s etc ... (12 times). This is obviously way too long to wait for a transaction timeout. (Imagine standing in line at a checkout for 10 minutes for your transaction to finish). In my company's existing products, we limit the TCP retry attempts to 4, which provides a more reasonable timeout. So, I think I need to change the TCP_MAXRXTSHIFT from 12 to another value. Maybe I can assign this to a global variable and use the sysctl interface to manipulate it? Any thoughts are appreciated, -- Matt __________________________________ Do you Yahoo!? The New Yahoo!
