Then take that output and feed it into Excel or another spreadsheet software to create the graph Very often a protocol analyst has to track TCP behavior, looking at sequence and acknowledge numbers. pcap -Y "display filter" -T fields -e frame. 12 and I am trying to filter SYN , SYN/ACK , ACK by inconsistencies. Maybe the tracing tool could not keep up with the high packet rate tracing unfiltered packets. How do I do this in wireshark without specifying an exact sequene number? Best regards, Tim. The window size is the line above the actual sequence number line, and in that graph it is very nice to see how the sequence numbers relate to the remaining window size. How can I filter out the protocol, sequence number, and ack using tshark? I could filter out other options as follow: Use the "-e" options listed below: In general to find the filter name select the item in the packet details pane and look at the name in parenthesis in the status bar TCP_Relative_Sequence_Numbers TCP Relative Sequence Numbers & TCP Window Scaling. Field name Description Type Versions; esp. seq==NUMBER", where "NUMBER" is the number you look for. number it displays 1-8 for the frame number. However, if by "Wireshark's relative sequence number" you're referring to the Easiest way to do is to select the sequence number in the decode pane of any TCP packet and then use the popup menu to "apply as column". It then adds meta data such as hardware based timestamp, sequence number and length and optionally truncates packets before forwarding as UDP to wireshark using RPCAP protocol. 5 Back to Display Filter Reference In your case, match up the sequence numbers of the data frames in the trace preceding the BlockAck Response and compare to the bitmap to see if they make sense.

How to Using this you can filter on ANY object in a response with dnp3. The easiest way to show this would be to filter for duplicate sequence numbers (I stand to be corrected on this). root _sta: Root STA Address: Ethernet or other MAC address: 1. so it's not "dropping back" to 0, but rather analyzing that it's a second TCP session with a new set of sequence numbers which Wireshark will assign new relative numbers for, starting at 0. If a packet meets the requirements expressed in your filter, then it is displayed in the list of packets. 1, use ip. From now on, it gets weird. It's easier on the eyes to track 1,000 to 3000 (relative seq#) rather than 3223. If you need a display filter for a specific protocol, have a look for it at the how to analyze the TCP sequence numbers through Wireshark. But note that the next sequence number only exists in packets that have TCP data, so it won’t be there for naked ACKs. aeth: ACK Extended Transport Header: Byte sequence: 1. Is there a way to see the Wireshark-like output of the original frame number? Between Packet 12 and 13 the cable is plugged in again.
