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

Synopsis

flow-export [ -h ] [ -d debug_level ] [ -f format ] [ -m mask_fields ] [ -u user:password:host:port:name:table ]

Description

The flow-export utility will convert flow-tools flow files to ASCII CSV, cflowd, pcap, wire, mySQL, and PGSQL format.

Options

-d debug_level

Enable debugging.

-f format

Export format. Supported formats are: 0 cflowd 1 pcap 2 ASCII CSV 3 MySQL 4 wire 5 PGSQL

-h

Display help.

-m mask_fields

Select fields for MySQL, PostgresSQL, 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.

-u user:password:host:port:name:table

Configure MySQL or PostgresSQL Access.

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

Examples

Export the flow-tools file flows to an MySQL Database. Include only SRCADDR, DSTADDR and DOCTETS.

flow-export -f3 -mSRCADDR,DSTADDR,DOCTETS -u "user:password:host:port:name:table" < flows

Bugs

The pcap format is a hack.
