Having the same SEQ but different ACKs is not an error or retransmission, but a normal ACK response if you have nothing new (that is LEN=0)  to send.

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
