We have a number of Linux servers for which I would like to capture netflow data to be processed by a netflow analyzer. I've been spoiled by the ease in which Mikrotik routers allow netflow data generation, but I haven't managed to find an opensource tool that is able to generate netflow data for multiple interfaces on a Linux system.I have come across but it seems quite buggy. Admittedly I haven't spent much time with it yet since I'd also like to evaluate some other possibilities. The other tool I've seen mentioned is, which appears to be GPL, but is not available as a free download since it is only offered for a fee.The servers on which I plan to generate netflow data are all Gentoo systems, but this shouldn't really make any difference. At most it means I would have to manually compile a tool from source.Summary: I'm looking for an opensource netflow generator that will work on Linux and allows capturing flows for multiple interfaces. Will do it, but is probably not the best choice.

Definitely check out; it's designed exactly for this. From the feature list:. Collects data through libpcap, Netlink/ULOG, NetFlow v1/v5/v7/v8/ - v9, sFlow v2/v4/v5 and IPFIX. Saves data to a number of backendsincluding memory tables, MySQL, PostgreSQL, SQLite and BerkeleyDB. Exports data to remote collectors through IPFIX, NetFlow v5/v9 andsFlow v5.

Install iftop. First, turn on EPEL repo on Linux. See how to install and enable epel repo on CentOS / RHEL / Scientific Linux v4.x/5.x/6.x for more information. Type the following yum command to install iftop on RHEL/CentOS/Fedora Linux: # yum -y install iftop Sample outputs: Fig.01: iftop installed using yum command. How do I use iftop command. Fprobe is a small application acts as NetFlow probe and forward NetFlow statistics to a NetFlow collector. This is how to install and configure fprobe on CentOS 5.

Replicates incoming IPFIX, NetFlow and sFlow packets to remote collectorsAmong many other things. Cannon fodder save disk adf.
