NAME
flow-export — Export flow-tools files into other NetFlow packages.

SYNOPSIS

flow-export [-h] [-d debug_level] [-f format] [-m mask_fields]

DESCRIPTION

The flow-export utility will convert flow-tools flow files to ASCII CSV, cflowd, or pcap format.

OPTIONS

-d debug_level
    Enable debugging.

-f format
    Export format. Supported formats are:
      0 cflowd
      1 pcap
      2 ASCII CSV

-h  Display help.

-m mask_fields
    Select fields for cflowd and ASCII formats. The mask_fields is built from a bitwise OR of the following:

    The default value is all fields applicable to the the flow file, or the cflowd INDEX mask applicabable to the export format.

EXAMPLES

Convert the flow-tools file flows to the cflowd file flows.cflowd. Include all fields.

  flow-export -f0 < flows > flows.cflowd

EXAMPLES

Convert the flow-tools file flows to the ASCII. Include the SRCADDR and DSTADDR fields.

  flow-export -f2 -m0x3000 < flows > flows.ascii

BUGS

The pcap format is a hack.
