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