Tcpflow is a TCP/IP Demultiplexer. Tcpflow is used to record traffic mainly between 2 hosts although it can be used to monitor thousands of connections. Tcpflow differs from other tools by actually capturing the real data and dumping it to a file we specify.

Network traffic monitoring in Linux using iptraf command Iptraf is much more detailed in its output compared to iftop command. Iptraf shows traffic summery based on the protocol of the traffic. It shows the summery for tcp,udp,icmp,ip traffic in its output. When traffic monitoring with an accessible web-gui, using third party utilities such as ntop-ng or Nagios is the best choice (versus re-creating such facilities from scratch). For further research on both configurable web-gui solutions, following are a few links to get started on research.

vnStat - a network traffic monitor for Linux and BSD vnStat is a console-based network traffic monitor for Linux and BSD that keeps a log of network traffic for the selected interface(s). It uses the network interface statistics provided by the kernel as information source. This means that vnStat won't actually be sniffing any traffic and also ensures light use of system resources regardless of Linux: How to measure daily/montly network traffic?
