From the README on the website: wmwave is dockapp for window maker to display statistical information about a current wireless ethernet connection. The current release is Version 0.4. wmwave has been tested under Redhat 5.2 with an Wavelan Silver WEP/IEEE card from Lucent Technologies. I have rewritten the network code for use with Bill Paul's wi(4) driver as it appears in FreeBSD 5.0-CURRENT and 4.4-STABLE. Support for other cards will not be integrated into this GPLed version.

libdnet provides a simplified, portable interface to several low-level networking routines, including network address manipulation, kernel arp(4) cache and route(4) table lookup and manipulation, network firewalling, network interface lookup and manipulation, and raw IP packet and Ethernet frame transmission. It is intended to complement the functionality provided by pcap(3).

Xferstats is a utility that parses wu-ftpd, ncftpd, and (special) apache xferlogs and gives various information and totals about the data transferred.

TAYGA is an out-of-kernel stateless NAT64 implementation for that uses the TUN driver to exchange IPv4 and IPv6 packets with the kernel. It is intended to provide production-quality NAT64 service for networks where dedicated NAT64 hardware would be overkill.

From the tcpcat README: Tcpcat is a simple program that is like `cat' but it works over TCP streams to allow you to cat from one host to another. The host common way to use this program whould be something like this: on host a: $ tcpcat -l 93255 | gzip -dc | tar xvf - on host b: $ tcpcat -h hosta:93255 file.tar.gz Another good use for this program is debugging network stuff. When debugging a newtork client or server you can pipe the output of tcpcat to a hex dump (I recomend xxd which comes with vim). Also it can act as a crude telnet server when invoded with --listen, --input, and --output, this mode is quite useful for network program debugging as well.

Produces a per-protocol breakdown of traffic by bytes and packets, with average and maximum transfer rates, for a given libpcap file (e.g., from tcpdump, ethereal, snort, etc.) Useful for getting a high-level view of traffic patterns.

This is a port of librdkafka, a C library implementation of the Apache Kafka protocol, containing both Producer and Consumer support. It was designed with message delivery reliability and high performance in mind, current figures exceed 800000 msgs/second for the producer and 3 million msgs/second for the consumer.

This is the NANOG traceroute program. This traceroute variant offers features such as MPLS label decode, Path MTU discovery, AS lookup, and spray mode. It is maintained by a collection of volunteers.

Linphone is an internet phone or Voice Over IP phone (VoIP). * With linphone you can communicate freely with people over the internet, with voice, video, and text instant messaging * Linphone makes use of the SIP protocol, an open standard for internet telephony. You can use Linphone with any SIP VoIP operator, including the free SIP audio/video service provided by www.linphone.org * Linphone is available for desktop computers: Linux, Windows, MacOSX, and for mobile phones: Android, iPhone, Blackberry

tcpmssd was written by Ruslan Ermilov <ru@FreeBSD.org> based on work done by Patrick Bihan-Faou <patrick@mindstep.com>. tcpmssd is a divert(4) program that adjusts outgoing TCP data so that the requested segment size is not greater than the amount allowed by the interface MTU. This is necessary in many setups to avoid problems caused by routers that drop ICMP Datagram Too Big messages. Without these messages, the originating machine sends data, it passes the rogue router then hits a machine that has an MTU that is not big enough for the data. Because the IP Don't Fragment option is set, this machine sends an ICMP Datagram Too Big message back to the originator and drops the packet. The rogue router drops the ICMP message and the originator never gets to discover that it must reduce the fragment size or drop the IP Don't Fragment option from its outgoing data.
