IP traceback is any method for reliably determining the origin of a packet on the Internet. The IP protocol does not provide for the authentication of the source IP address of an IP packet, enabling the source address to be falsified in a strategy called IP address spoofing , and creating potential internet security and stability problems.
In computing, traceroute and tracert are diagnostic command-line interface commands for displaying possible routes (paths) and transit delays of packets across an Internet Protocol (IP) network. The command reports the round-trip times of the packets received from each successive host (remote node) along the route to a destination.
iproute2 is an open-source project released under the terms of version 2 of the GNU General Public License. Its development is closely tied to the development of networking components of the Linux kernel. As of December 2013, iproute2 is maintained by Stephen Hemminger and David Ahern.
This is a list of the IP protocol numbers found in the field Protocol of the IPv4 header and the Next Header field of the IPv6 header. It is an identifier for the encapsulated protocol and determines the layout of the data that immediately follows the header. Both fields are eight bits wide.
iptables is a user-space utility program that allows a system administrator to configure the IP packet filter rules of the Linux kernel firewall, implemented as different Netfilter modules. The filters are organized in a set of tables, which contain chains of rules for how to treat network traffic packets.
BIRD (recursive acronym for BIRD Internet Routing Daemon [2]) is an open-source implementation for routing Internet Protocol packets on Unix-like operating systems. It was developed as a school project at the Faculty of Mathematics and Physics, Charles University, Prague, [3] and is distributed under the GNU General Public License.
The r-commands were developed in 1982 by the Computer Systems Research Group at the University of California, Berkeley, based on an early implementation of TCP/IP (the protocol stack of the Internet). [2] The CSRG incorporated the r-commands into their Unix operating system, the Berkeley Software Distribution (BSD).
The ipconfig command supports the command-line switch /all. This results in more detailed information than ipconfig alone. An important additional feature of ipconfig is to force refreshing of the DHCP IP address of the host computer to request a different IP address. This is done using two commands in sequence.
