Hi Victor, Have a look at this page: http://www.wireshark.org/docs/dfref/t/tcp.html You can use display filter on the following fields: tcp.analysis.retransmission tcp.analysis.fast_retransmission tcp.checksum_bad For TCP checksums, please also refer to this page: http://wiki.wireshark.org/TCP_Checksum_Verification For retransmissions, also refer to this page: http://wiki.wireshark.org/PacketLoss HTH Abhik.

Hi, how can i locate retransmission error for TCP sequence in wireshark capture ? Should I look for ACK with repeated sequence number ? For example: [ACK] Seq = 1355 Ack = 13409 ... [ACK] Seq = 1355 Ack = 13500 How can i detect checksum errors from the capture ? Thanks, -vvv ___________________________________________________________________________ Sent via: Wireshark-users mailing list <wireshark-users () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-users Unsubscribe: https://wireshark.org/mailman/options/wireshark-users mailto:wireshark-users-request () wireshark org ?subject=unsubscribe
