网络连接关闭
请帮我解码以下内容。我的网络有问题,无法找出问题所在。以下是我们通过运行 OPNET 软件从捕获中获得的解码摘要。
我认为连接 2 是成功的,客户端以 FIN 结束,而连接 1 过早结束并发出 RST,可能是什么原因..?
连接1 帧源目标解码摘要
480 服务器客户端 D=3590 S=443 FIN ACK=3832271994 SEQ=1338775336 LEN=0 WIN=11088 481 客户端 服务器 D=443 S=3590 ACK=1338775337 SEQ=3832271994 LEN=0 WIN=64512 502 客户端 服务器 D=443 S=3590 RST ACK=1338775337 SEQ=3832271994 LEN=0 WIN=0
连接 2
855 服务器客户端 D=3600 S=443 FIN ACK=3778329063 SEQ=3650187663 LEN=0 WIN=26328
856客户端 服务器 D=443 S=3600 ACK=3650187664 SEQ
=3778329063 LEN=0 WIN=63297 857 客户端 服务器 D=443 S=3600 FIN ACK=3650187664 SEQ=3778329063 LEN=0 WIN=63297
859 服务器 客户端D=3600 S=443 ACK=3778329064 SEQ=3650187664 LEN=0 WIN=26328
总之,连接结束是,
1 - 服务器:FIN,客户端:RST
2 - 服务器:FIN,客户端:FIN
Please help me decode the following. I have a problem in the network, unable to figure out where it is. Follow is the decode summary we got from the capture by running the OPNET software.
I think Connection 2 is successful, where the client ends with FIN, and connection 1 ends prematurely issuing RST, what could be the reasons..?
Connection 1
Frame Source Destination Decode Summary
480 Server Client D=3590 S=443 FIN ACK=3832271994 SEQ=1338775336 LEN=0 WIN=11088
481 Client Server D=443 S=3590 ACK=1338775337 SEQ=3832271994 LEN=0 WIN=64512
502 Client Server D=443 S=3590 RST ACK=1338775337 SEQ=3832271994 LEN=0 WIN=0
Connection 2
855 Server Client D=3600 S=443 FIN ACK=3778329063 SEQ=3650187663 LEN=0 WIN=26328
856 Client Server D=443 S=3600 ACK=3650187664 SEQ=3778329063 LEN=0 WIN=63297
857 Client Server D=443 S=3600 FIN ACK=3650187664 SEQ=3778329063 LEN=0 WIN=63297
859 Server Client D=3600 S=443 ACK=3778329064 SEQ=3650187664 LEN=0 WIN=26328
In summary the connection endings are,
1 - Server: FIN, Client: RST
2 - Server: FIN, Client: FIN
