ipt_NETFLOW is a module for the Linux 2.6 kernel that allows for the collection and analysis of network flow data. It can be used to identify network traffic patterns and monitor network usage for security and performance purposes.
The iptables Netflow module package is an incredibly efficient and quick Netflow exporting module that has been designed notably for Linux routers that bear a heavy network load. Based on iptables, it does not use conntrack to ensure flawless performance. In this software review, we discuss the installation of the iptables Netflow module package, how to run it, and the different options it offers.
Installation Instructions:
To install the package, you will need to download the iptables/netfilter source, match it with your installation, or perform a fresh installation. Ensure that you have unloaded any previously installed Netflow modules.
After unpacking the .tar.bz2 package, configure the Makefile variables pointed to the right place and the correct version of the unpacked iptables source. Troubleshooting provides instructions on how to tackle issues that may arise during the installation process.
Running the Module:
Once installed, the module can be loaded via insmod or modprobe commands. You have the option to use the command line or configure it through the /etc/ to modules.conf or modprobe.conf files, enabling you to add parameters and control them via sysctl. To view statistics, you can access the /proc/net/stat/ipt_netflow and /proc/slabinfo files.
To facilitate the whole process and direct all traffic into the Netflow module, we have provided a simple example.
Options:
The iptables Netflow module package has several options that enable you to control, guide, and manipulate flows according to your needs. Firstly, you can decide where to export netflow via setting the destination IP address. You also can mirror flows to two or more addresses and set the inactive and active timeouts. Debug level, buffer size, hash table bucket size, maximum number of flows to account, and different aggregation rules, including netmask and port aggregation, are also available.
In conclusion, the iptables Netflow module package is a handy tool that provides solutions to tackle heavy network load among Linux routers. Its efficiency, quickness, and optimization make it stand out from the crowd. With a straightforward installation process, running of the module, and the variety of options it provides, this module is ideal for Linux users who demand a reliable and efficient tool.
