User’s Guide – version 3.1.3 NetFlow Tracker

Using sflowtool to Convert sFlow Records to NetFlow
NetFlow Tracker does not directly support devices which export sFlow records;
however, the developer of sFlow provides a tool to convert sFlow records to NetFlow
records, available at http://www.inmon.com/technology/sflowTools.php
. This is a
simple command-line utility which can be run as a daemon on Unix or a service on
Windows by using one of the many free service installers available. The required
command line options are:
-p <port>
This sets the incoming port number; the device should be configured to send
sFlow records to this port on the address of the server running sflowtool.
-c <address>
This sets the address of the NetFlow Tracker server.
-d <port>
This sets the port on the NetFlow Tracker server that NetFlow records are
sent to; this must be one of the ports configured in the Listener Ports
settings
page (2055 is monitored by default).
-S
This asks the tool to create NetFlow packets with the same source address as
the incoming sFlow records, thus tricking NetFlow Tracker into believing that
the NetFlow packets came directly from the device. Note that the tool will need
to be run as root on Unix systems or as an administrator on Windows for this
to work. If you use a service installer on Windows to run the tool it will be run
under the built-in system account which is similar to an administrator account.
Note that support for this feature depends upon how the tool was compiled
from source code and on operating system support – Windows XP does not
support IP address spoofing, for example, and as a result recent Windows
versions of the tool do not offer the feature on any version of Windows.
-e
This includes the peer AS numbers in the generated NetFlow records rather
than the default origin AS numbers.
