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.
MacTCP is the standard TCP/IP implementation for the classic Mac OS through version 7.5.1. It is the first application-independent implementation of a TCP stack for a non-Unix platform [1] [2] and predates Winsock by over 5 years.
Unix-like operating systems commonly implement IP address blocking using a TCP wrapper, configured by host access control files /etc/hosts.deny and /etc/hosts.allow.. Both companies and schools offering remote user access use Linux programs such as DenyHosts or Fail2ban for protection from unauthorized access while allowing permitted remote access.
Nmap (Network Mapper) is a network scanner created by Gordon Lyon (also known by his pseudonym Fyodor Vaskovich). [5] Nmap is used to discover hosts and services on a computer network by sending packets and analyzing the responses.
IP layer transparency could be also defined from the point of server's view. If the connection is transparent, the server sees the real client IP. If it is non-transparent, the server sees the IP of the intermediate host. Transparency at the application layer means the client application uses the protocol in a different way.
Open Transport was the name given by Apple Inc. to its implementation of the Unix-originated System V STREAMS networking stack.Based on code licensed from Mentat's Portable Streams product, Open Transport was built to provide the classic Mac OS with a modern TCP/IP implementation, replacing MacTCP.
ipconfig in Mac OS X serves as a wrapper to the IPConfiguration agent, and can be used to control the Bootstrap Protocol and DHCP client from the command-line interface. [8] For example, you can release and renew an IP address if it happened to be assigned incorrectly by the DHCP server during the automated assignment process. [9]
Martian packets commonly arise from IP address spoofing in denial-of-service attacks, [2] but can also arise from network equipment malfunction or misconfiguration of a host. [ 1 ] In Linux terminology, a Martian packet is an IP packet received by the kernel on a specific interface, while routing tables indicate that the source IP is expected ...
