Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Date: Mon, 24 Jan 2000 22:37:57 -0800 From: George Neville-Neil Sender: owner-freebsd-net@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org Hi Folks, Can anyone tell me why a recieving TCP does not send an ICMP Port Unreachable error if there is no matching PCB for the packet that is received? I looked a bit at Volume II and it just shows that the source does not have this, nor does the FreeBSD 3.3 source. (At least it's not in tcp_input() where we lookup the PCB).
