2. npcapindex

This utility produces an index file (with the same format of the index produced by n2disk) from a pcap file.

Available options:

[-i ] <pcap file>                    | Pcap file to index
[-o] <index file>                    | Index file
[-f ] <bpf>                          | BPF filter to select packets to index
[-G] <mode>                          | Compute index on tunnel content (GTP-U)
                                     | 1 - Index both inner and outer headers
                                     | 2 - Use inner header as outer header
[-I] <version>                       | Specify the index version:
                                     | 1 - Standard index (default)
                                     | 2 - Flow-based index
[-v]                                 | Verbose
[-h]                                 | Help
