我在网络跟踪中看到,我的客户端正在向 DC 发送以下 ACK 帧:
Frame: Number = 87641, Captured Frame Length = 54, MediaType = ETHERNET
+ Ethernet: Etype = Internet IP (IPv4),DestinationAddress:[AA-AA-AA-AA-AA-AA],SourceAddress:[AA-AA-AA-AA-AA-AA]
+ Ipv4: Src = XXX.XXX.XXX.XXX(CLIENT), Dest = YYY.YYY.YYY.YYY, Next Protocol = TCP, Packet ID = 26829, Total IP Length = 40
- Tcp: [Bad CheckSum]Flags=...A...., SrcPort=14229, DstPort=LDAP(389), PayloadLen=0, Seq=4175359382, Ack=1985975784, Win=1357
- SrcPort: 14229
- DstPort: LDAP(389)
- SequenceNumber: 4175359382 (0xF8DEED96)
- AcknowledgementNumber: 1985975784 (0x765F95E8)
+ DataOffset: 80 (0x50)
+ Flags: ...A....
- Window: 1357
- Checksum: 0xDEAD, Bad
- UrgentPointer: 0 (0x0)
校验和 0xDEAD 是否表示某种迹象?
