flow-tools 0.68 Description:
flow-tools is a set of programs for processing and managing NetFlow exports from Cisco and Juniper routers. The tools included are: flow-capture, flow-cat, flow-dscan, flow-expire, flow-export, flow-fanout, flow-filter, flow-gen, flow-header, flow-import, flow-mask, flow-merge, flow-nfilter, flow-print, flow-receive, flow-report, flow-send, flow-split, flow-stat, flow-tag, and flow-xlate. Flow data is collected and stored by default in host byte ordera nd the files are portable across every endian architectures. Commands that utilize the network use a localip/remoteip/port designation for communication. "localip" is the IP address the host will use as a source for sending or bind to when receiving NetFlow PDU's (ie the destination address of the exporter. Configuring the "localip" to 0 will force the kernel to decide what IP address to use for sending and listen on all IP addresses for receiving. "remoteip" is the destination IP address used for sending or the expected address of the source when receiving. If the "remoteip" is 0 then the application will accept flows from any source address. The "port" is the UDP port number used for sending or receiving. When using multicast addresses the localip/remoteip/port is used to represent the source, group, and port respectively.
