||
| 5 | # The Python script indexcap.py does the same thing. |
||
| 6 | # |
||
| 7 | # This script extracts the protocol names contained in a given capture file. |
||
| 8 | # This is useful for generating a "database" (flat file :-)) of in what file |
||
| 9 | # a given protocol can be found. |
||
| 10 | # |
||
| 11 | # Output consists of the file name followed by the protocols, for example: |
||
| 12 | # /path/to/the/file.pcap eth ip sctp |
