Feature: System Administration
Linux is an excellent platform for network administration. If you want to monitor your network traffic, you can find many tools -- some accessible from a Web interface, others using a graphical interface -- but nothing beats the speed of the command line. Command-line tools are also useful in shell scripts, where they can help you perform complex tasks. Here's a handful of my favorites for monitoring network traffic.
Atop is a system and process manager that displays network traffic, along with other useful information such as CPU consumption, memory usage, and a process list. Atop has a handful of options to be passed to at startup. To see network network-related information and save it to a log file located in /var/log, start the application with atop -N > /var/log/atopnet.log.
