Tcptrack is a packet sniffer software that shows TCP connections as 'top' does. It's a useful tool for monitoring network traffic and analyzing it in real-time.
In order to use tcptrack, you'll need to ensure that you have libpcap 0.7.2 or higher installed. Once you've confirmed this requirement, building and installing the software is as simple as running two commands: './configure' and 'make # make install'.
When you're ready to start using tcptrack, all you need to do is specify an interface for the software to sniff. This can be done easily with the command: '$ tcptrack -i eth0'. Additionally, users have the option to provide a pcap filter expression with the same command structure. For example, '$ tcptrack -i eth0 src or dst 192.168.33.92 and port 80' will filter for connections with a source or destination address of 192.168.33.92 and port 80.
One of the exciting new features of tcptrack's most recent release is the inclusion of a new sort option for displaying connections by total bytes transferred. Furthermore, with the addition of a way to cycle through all the sort options, users can easily customize their view in a way that is most helpful to them.
Overall, tcptrack is a reliable and lightweight software option for those looking to monitor their TCP connections with ease.
