Content-Type: text/plain; charset=gb2312 Content-Transfer-Encoding: 7bit Content-Transfer-Encoding: 7bit Sender: owner-freebsd-net@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org My mail server caught a cold yesterday. So I think maybe there were some letters missed. Senders, please kindly re-send the letters concerning "drop packet" to my personal email box. Has any one response my question? I here ask again. After reading the replies, I am still not very clear about some points. Why 50 pkts for an interface queue? 50 sounds like not enough, if I use FreeBSD as a router. How many should I specify if I custmize the kernel or I use as large as possible?? Another question: According to the TCP header specification, 16 bits receive window should be 65536 bytes in maximum. But I can not reach this high, only 16384 bytes. tcpdump shows that although the window is annouced with 64k, sender can only send 16k data without ack. I am confused.
