We don't send a RST, we just silently drop the connection. However, at the point we're talking about, we're already past the 3-way handshake, so either way the connection has been lost. Heh, actually, I take that back. With a syncookie, a retransmitted ACK should end up reestablishing the connection. Clever... I think that you're referring to the case where we receive an initial SYN, and the listen queue is full. With the syncache/syncookies, this is no longer a problem; either a syn cookie is returned, or the syn is silently dropped (depending on whether or not syn cookies are enabled.) With the pre-syncache code, yes, a RST was sent at that time. Mike "Silby" Silbersack To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-net" in the body of the message
