Exact PCAP Match
Exact PCAP Match (exact-pcap-match
) is a tool used to match packets in two separate files. It outputs timestamps, timestamp deltas (latency) and the packet data of matched packets in a .csv
file.
Where timestamp deltas are shown, they are produced from reference_file.timestamp minus input_file.timestamp
.
The following table lists all commands available:
Short | Long | Default | Description |
---|---|---|---|
r | reference | (required) | The reference file to use for matching. |
i | input | (required) | The file to compare against the reference file. |
c | csv | (required) | The .csv file to write matching packet statistics to. |
R | ref-miss | (optional) | The .csv file to store reference packet misses. These are packets which were present in the reference file but were not found in the input file. |
I | inp-miss | (optional) | The .csv file to store input packet misses. These are packets which were present in the input file but were not found in the reference file. |
f | format | (required) | The input file format. Valid values are pcap or expcap . |
O | offset-ref | 0 | Start matching packets in the reference file from this packet offset onwards. |
o | offset-inp | 0 | Start matching packets in the input file from this packet offset onwards. |
M | max-ref | -1 (no limit) | Limit the amount of packets in the reference file to match. |
n | num-chars | 64 | The number of bytes from matched packets to output in the packet data field of the .csv file. |
v | verbose | (flag) | Enables verbose output printing. |
