Packet Sender is an open source utility to allow sending and receiving TCP and UDP packets. It also supports TCP connections using SSL, intense traffic generation, HTTP(S) GET/POST requests, and panel generation. It is available for Windows, Mac, and Linux. It is licensed GNU General Public License v2 and is free software. [1]
It allows the user to display TCP/IP and other packets being transmitted or received over a network to which the computer is attached. [3] Distributed under the BSD license, [4] tcpdump is free software. Tcpdump works on most Unix-like operating systems: Linux, Solaris, FreeBSD, DragonFly BSD, NetBSD, OpenBSD, OpenWrt, macOS, HP-UX 11i, and AIX.
The statistics output covers TCP/UDP payload only (not protocol overhead) and is generally displayed by default in KiB/s (kibiBytes per second) instead of kb/s (kilobits per second), but it can be configured to be displayed in other ways on some implementations. The reported throughput is more accurately calculated on the receive side than the ...
Tcpcrypt provides opportunistic encryption — if either side does not support this extension, then the protocol falls back to regular unencrypted TCP. Tcpcrypt also provides encryption to any application using TCP, even ones that do not know about encryption. This enables incremental and seamless deployment. [6]
The uIP is an open-source implementation of the TCP/IP network protocol stack intended for use with tiny 8- and 16-bit microcontrollers.It was initially developed by Adam Dunkels of the Networked Embedded Systems group at the Swedish Institute of Computer Science, licensed under a BSD style license, and further developed by a wide group of developers.
By default, statistics are shown for the TCP, UDP, ICMP, and IP protocols. If the IPv6 protocol for Windows XP is installed, statistics are shown for the TCP over IPv6, UDP over IPv6, ICMPv6, and IPv6 protocols. The -p parameter can be used to specify a set of protocols. Yes Yes Yes Yes Yes Yes Yes Yes -t: Display only TCP connections. No Yes ...
iperf, Iperf, or iPerf, is a tool for network performance measurement and tuning. It is a cross-platform tool that can produce standardized performance measurements for any network. iperf has client and server functionality, and can create data streams to measure the throughput between the two ends in one or both directions.

The port mapper service always uses TCP or UDP port 111; a fixed port is required for it, as a client would not be able to get the port number for the port mapper service from the port mapper itself. The port mapper must be started before any other RPC servers are started. The port mapper service first appeared in SunOS 2.0.
