I was testing b/w two 4.0 boxes and saw the following scenario. Server side ----------- 10:14:41.260613 server.7000 > client.1136: P 1:101(100) ack 32001 win 65535 (DF) 10:14:41.260709 server.7000 > client.1136: F 101:101(0) ack 32001 win 65535 (DF) 10:14:41.652936 client.1136 > server.7000: F 32001:32001(0) ack 101 win 17520 (D F) 10:14:41.653075 server.7000 > client.1136: F 101:101(0) ack 32002 win 65535 (DF) 10:14:41.659388 client.1136 > server.7000: F 32001:32001(0) ack 102 win 17520 (D F) 10:14:41.659485 server.7000 > client.1136: . ack 32002 win 65535 (DF) 10:14:41.989824 client.1136 > server.7000: . ack 102 win 17520 (DF) Client side ----------- 18:10:18.484731 server.7000 > client.1136: P 1:101(100) ack 32001 win 65535 (DF ) 18:10:18.485193 client.1136 > server.7000: F 32001:32001(0) ack 101 win 17520 (D F) 18:10:18.490679 server.7000 > client.1136: F 101:101(0) ack 32001 win 65535 (DF) 18:10:18.490726 client.1136 > server.7000: F 32001:32001(0) ack 102 win 17520 (D F) 18:10:18.818621 server.7000 > client.1136: F 101:101(0) ack 32002 win 65535 (DF) 18:10:18.818626 server.7000 > client.1136: . ack 32002 win 65535 (DF) 18:10:18.818663 client.1136 > server.7000: . ack 102 win 17520 (DF) If I remember right the last two ACKS are not necessary during simultaneous close? jayanth To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
