How to configure Fedora linux as a router?
I'v installed the NetFlow Analyzer on a Fedora Core 3 server, and soon I figured out that NetFlow Analyzer uses NetFlow data which is generated by a router, so it needs a router. i just to need to monitor and count bandwidth traffic of my office , but i have not any router but just a switch through which all office pc's are connected to the server and to internet. so how i configure the server as a router , or is there any other way, any comment will be appreciated. thanks.
License Details
Hi, We are presently evaluating the Netflow product. The product works as per our requirement, however i needed more clarity on the licence needed, If we buy the product with 20 interface pack, does it mean that a total of 20 interface can be managed OR 20 interface per device(router)? Thanks and Regards, FG
Virtual netflow interface network address
I'm currently evaluating your software for my company. We're using a WRT54G Linksys router with a sveasoft firmware upgrade. This firmware is a linux os and has a module which emulates the cisco netflow functionality called rflow. Netflow Analyzer has been working great for this setup thus far. I'm having a common difficulty in displaying OUT flows. I understand that netflow is all ingress, and that you must set the network interface address on the router and open all flows to be able to get IN and
Windows 2000 pdf export
We had Netflow analyzer running on windows server 2003 and we could not use the pdf export feature. Support told us that it was a windows 2003 issue. So we backed up our Adventnet directory,blew away our installation of windows 2003 and installed windows server 2000. We then installed Netflow Analyzer again to the same location and then copied our backup over the top. However the pdf export option still does not work. We have tried IE6 and Mozilla Firefox 1 on the clients and no success in either.
NetFlow
Hi, Netflow is a really cool software. But it does not support NetFlow v9. and also it works only on certian router. I have Cisco 2621, 1721 & 3COM pathbuilder II S400. It work only on 2621 and not on 1721? I there any reson for it. Both the routers have IOS greater than 12 (which is reqired for netflow). Does 3COM support Net Flow ?? My company is planning to purchace this software, only if it work on all routers. Regards, Kern Martis email: kern_martis@cms.com

PDF Export
Hi, i tried to install NetFlow Version 4.0.0 Build 4002 on a Windows 2003 Server, and is working fine. I've problems with PDF export, because the operation hang and Microsoft Internet Explorer 6 resent a blank page with title bar http://IP_ADDR/servlet/CReportPDFServlet?pdf=true. I tried to reinstall Acrobat Reader 7, but it doesn't work. Please, can you help me? Regards. Mirko
95/5 reports?
Does anyone know if Netflow Analyzer can generate 95/5 reports in bps? I'm looking for the standard ISP style - measure every 5 min. both in and out - discard the top 5% of measurements and deliver the 95% measurement. A small caveat is that I'd like to specifically report on traffic inbound and outbound from my networks to the rest of the world and discard traffic intra-network. Any help/suggestions would be appreciated. Thanks, Nate

Use Oracle 9i in NetFlow Analizer
New Applications
Do you plan on providing any "updated" application mappings to include ports like BitTorrent (6881-6889), Emule (4662), etc. While I realize that this can be done by the admin manually, an occassional update would help to identify many of the newer P2P applications for bandwidth mgmt purposes for the masses.
Can't add devices
Hi, I can't add any devices to my Netflow install. I had installed the trial version, and when the trial expired I purchased a 10 interface license. According to the License Managment scrren I have 4 remaining interfaces, however, I can't find anywhere to be able to add additional devices. Any suggestions?

Using release 4002, i still get 100% utilization+
I read the other thread regarding 100%+ utilization and it seems to infer that this was solved in 4002. I just installed 4002 and i still have % above 100%. The link is a T1 and the correct values have been applied to the interface.

Catalyst 6500 interfaces
Hi, I just asked Netflow tool to query a Catalyst 6500 and it returned the 6500 interfaces as BT Fiber Gigabit Interface, as long haul fiber, short haul... with no specific details i.e. interface number 1/2, 1/3 etc. It is not an SNMP problem (i have put the right community name) But how can i know to which interface Netflow refers to????

Packets exported but Netflow Analyzer couldn't detect?
Hi, Is there any reason why Netflow couldn't detect packets coming in although from router we can see clearly packets flow exported? Both the destination IP and port are correctly configured. The only thing is, this router worked fine before. Only after I disabled netflow on it and deleted from Netflow Analyzer, Netflow Analyzer couldn't detect the router although I have enable back netflow from the same router.
Some questions
Hi We have the trial version of Netflow Analyzer 4 running and we will soon be purchasing it. One thing we have had problems with is the sorting of devices in the All Devices-Dashboard View. We have noticed that some of the devices are sorted alphabetically but we have groups of devices further down in our list that are not where they belong in the list (for example we have a group of devices that are sorted alphabetically that come after a device starting with W) Is there a way to make it resort

Hi, I managed to installed NetFlow Analyzer and from the webpage I could see packets coming in increased when I reload the page.

How to add license details?
I had the trial version of Netflow running, and the license has expired. I have purchased the 10 interface version and was wondering how or what I need to do to get it running again.
Feature request!
Hi, As well as being able to say "top-n" applications or whatever, I'd also like to be able to say: - "bottom-n". Sometimes you're interested in the very very tiny details which can get lost in the "others" category. - "top-n without the first one". Sometimes a bulk activity like a backup will take up (for example) 95% of the volume for a specified period, reducing everything else to next-to-nothing on the graph. By saying "top-n without the first one" I'd be able to ignore the bulk activity and

Netflow Analyser 4 Questions
Hi, I have a number of questions in regards to this great product. Licencing - What is the initial number of interfaces that can be managed, using the demo we are monitoring over 70 interfaces. Ultimately we would need to licence around 300 interfaces - probably split across 2 machines due to the flow rates. Database - An SQL database is utilised. What is the data reduction method used? Does the hourly data get aggregated/compacted in the daily totals etc. We would like to able to go back in time
decrease average time on graphs
On the traffic graphs average time is set to 10 min. Can I change this value some where. I need more precisely graph because i usually have some pick on network. I want to set this value to 3 or 5 min.
Out Traffic
Hello, I've been evaluating the Netflow Analyzer product for a couple days now.. Comaped to the other products in this catagories, your seems like a very good value. Anyway, I cannot get the application to display Outbound traffic on my interfaces. I read the FAQ and it says that I'd need to enable netflow on every interface traffic passes to get this info, but after doing this, I still do not see it. I am monitoring an edge router with 1 gigabit int and two POS's. I get inbound traffic on all of
Netflow Analyzer
Right now, the analyzer collects export v5. Will the analyzer be able to collect export v8? If so, would that be an upgrade or a new version?
Slow performance and "No results to display" mess
I've running NetFlow Analyzer for about four hours. Whenever I require a report such as TCP_App port , source, destination or conversation display it gets very slow often halted. Some times I get the "No results to display" message. I'm running it on a Penitum III 1GHz Dual processor, 1GB RAM HP Server, RedHat 8.0 . CPU load doesn't reach 30% utilization. Thanks, EBreton
Additional report types?
Our "campus" is comprised of five undergraduate and two graduate institutions. The "campus" has its own class B address and that IP space is divided among the various institutions. The cost of the internet connection is divided based on the amount of traffic each institution does. What I need to be able to do is to generate a report for a specific network range to get a "total" traffic in/out for that institution. The custom report gets part way there in that it I can specify a network range, but
NetFlow Analyser and OpManager on the same box?
Hi, I've got eval copies of NetFlow Analyzer and OpManager running on the same box. I note that they both have their own copies of MySQL running to log data. - Can they be configured to use a single instance of MySQL? - I guess you're using MySQL for cross-platform compatibility? It's a long shot, but would it be possible to use a different SQL backend like SQL Server? - You can tweak OpManager to discard data once it's past a certain age. Can you do the same thing with NetFlow Analyzer? many thanks,
Install Error unpacking JAR files
From what we've been able to see, this could be a really great app. However, we're having problems getting it to install completely. We get to the "Unpacking JAR files" part of the install, which takes quite a long time, but it eventually fails with a critical error that backs out of the install and uninstalls everything. However, being that we're used to Windows apps that don't install themselves correctly, we noticed that if we kill the install process when the error comes up then the uninstall
slow reporting
I've been running NetFlow Analyzer for about 9 hrs now and I'm noticing a big slow down in getting a report result, for example, when I click on "TCp_App" in a "last hour" report for an interface. In one case, it took 37 minutes to get the result displayed. The router that is providing the NetFlow data is very busy as we have 5000+ students, etc. Is there a way to speed this up? Is this a memory allocation issue with mySQL? I really like the product but waiting 30 minutes for a report is a bit much.
Netflow - not working with 4500 sup 4 w/ netflow card
Ok, I got my 4500 configured for netflow and I can see by issuing a "Show Ip flow export" that it is sending to the computer with Netflow Analyzer. I never get a listing for the router at all... If I switch the router from version 5 netflow to version 1, I'll get a warning in the dashboard that it is receiving ver 1 packets, but if I switch it back to ver 5, I get nothing. Any clues? FYI - On the 4500 w/ net flow, there is only a "global" way to enable netflow in that, all interfaces are enabled.
Showing dropped packets?
Hi, I'm exporting data from a Cisco 2621XM to a demo version of Netflow Analyser 4. Everything seems to be working well. However, I was looking at an application report, and UDP_App was listed. Drilling down to see which ports were involved, I saw this: SrcIP:SrcPort DestIp:DestPort a.b.c.d:51423 w.x.y.z:1026 Looking in my router logfiles, I saw that this flow was actually dropped by an ACL. So: - Is it usual for packets dropped by ACLs to appear in the Analyser? - I only investigated this in any
