iftop

Compare

  Analyzed about 4 hours ago

iftop does for network usage what top(1) does for CPU usage. It listens to network traffic on a named interface and displays a table of current bandwidth usage by pairs of hosts. Handy for answering the question "why is our ADSL link so slow?".

netsniff-ng

Compare

  Analyzed about 22 hours ago

netsniff-ng is is a free, performant Linux network analyzer and networking toolkit. The gain of performance is reached by zero-copy mechanisms, so that the kernel does not need to copy packets from kernelspace to userspace and vice versa. netsniff-ng consists of much more than only a network ... [More] analyzer. Next to the zero-copy sniffer itself, further tools like trafgen, a powerful zero-copy network packet generator, or ifpps, a tool that provides top-like kernel networking statistics, and curvetun, a lightweight curve25519-based multiuser IP tunnel, are being shipped.

tcpreplay

Compare

  Analyzed about 23 hours ago

Tcpreplay is a suite of BSD licensed tools written by Aaron Turner for UNIX (and Win32 under Cygwin) operating systems which gives you the ability to use previously captured traffic in libpcap format to test a variety of network devices. It allows you to classify traffic as client or server, rewrite ... [More] Layer 2, 3 and 4 headers and finally replay the traffic back onto the network and through other devices such as switches, routers, firewalls, NIDS and IPS's. Tcpreplay supports both single and dual NIC modes for testing both sniffing and inline devices. Tcpreplay is used by numerous firewall, IDS, IPS and other networking vendors, enterprises, universities, labs and open source projects. [Less]

NetHogs - 'net top' per process

Compare

  Analyzed about 4 hours ago

NetHogs is a small 'net top' tool. Instead of breaking the traffic down per protocol or per subnet, like most tools do, it groups bandwidth by process. NetHogs does not rely on a special kernel module to be loaded.
