Never heard of it. I'll give it a shot. Another project that uses argus also looks interesting.. http://nautilus.oshean.org/wiki/Periscope -----Original Message----- From: Ken A [mailto:ka () pacific net] Sent: Monday, December 06, 2010 4:04 PM To: nanog () nanog org Subject: Re: ipfix/netflow/sflow generator for Linux Have you considered argus? It can deliver "argus flows" from multiple interfaces. From http://www.qosient.com/argus/ :
Argus can be considered an implementation of the architecture described in the IETF IPFIX Working Group. Argus pre-dates IPFIX, and the project has actively contributed to the IPFIX effort, however, Argus technology should be considered a superset of the IPFIX architecture, providing "proof of concept" implementations for most aspects of the IPFIX applicability statement. Argus technology can read and process Cisco Netflow data, and many sites develop audits using a mixture of Argus and Netflow records.

fprobe doesn't work properly because it has the input and output interface IDs as both 0. In Scrutinizer, this makes the flow look like all the data came in the interface and immediately left via the same interface. Also, this causes problems when running multiple instances of fprobe. This seems to be the issue with most of the flow software I've tried. -----Original Message----- From: Samuel Petreski [mailto:sp446 () georgetown edu] Sent: Monday, December 06, 2010 3:38 PM To: 'Thomas York'; nanog () nanog org Subject: RE: ipfix/netflow/sflow generator for Linux I've used fprobe with great success.

I need to do someIPaccounting/reporting and am currently trying to use Scrutinizer.Scrutinizercan use netstream, jstream, ipfix, netflow, and sflow data without qualms. My only issue is that I can't seem to find any good software for Linuxthatworks with multiple interfaces to generate the flow information. I'vetriedndsad, nprobe, softflowd, host sflow, and ipcad without much luck. Most of the software only works on one interface (which is useless as I need to do accounting for numerous interfaces). I've had the best luck with ipcad. The only thing that seems to not workwithit is that it doesn't correctly give the interface number in the flow information. It refers to all interfaces as interface 65535. I've triedthe configoption for ipcad to map an interface directly to an SNMP interface ID, but that option of the config file seems to be ignored. Ntop functionally does exactly what I need, but it's extremely buggy. It segfaults after a few minutes, regardless of Linux distro or Ntopversion.So..any ideas on what I can do to get good flow information from our Linux routers?
