  2. Promiscuous mode - Wikipedia

    en.wikipedia.org/wiki/Promiscuous_mode

    In IEEE 802 networks such as Ethernet or IEEE 802.11, each frame includes a destination MAC address. In non-promiscuous mode, when a NIC receives a frame, it drops it unless the frame is addressed to that NIC's MAC address or is a broadcast or multicast addressed frame. In promiscuous mode, however, the NIC allows all frames through, thus ...

  3. Wireshark - Wikipedia

    en.wikipedia.org/wiki/Wireshark

    Wireshark is very similar to tcpdump, but has a graphical front-end and integrated sorting and filtering options.. Wireshark lets the user put network interface controllers into promiscuous mode (if supported by the network interface controller), so they can see all the traffic visible on that interface including unicast traffic not sent to that network interface controller's MAC address.

  4. echo (command) - Wikipedia

    en.wikipedia.org/wiki/Echo_(command)

    In computing, echo is a command that outputs the strings that are passed to it as arguments. It is a command available in various operating system shells and typically used in shell scripts and batch files to output status text to the screen [1] or a computer file, or as a source part of a pipeline.

    The standard utility program that alters this flag programmatically is the stty command, using which the flag may be altered from shell scripts or an interactive shell. [25] The command to turn local echo (by the host system) on is stty echo and the command to turn it off is stty-echo. [26] [fn 2]

    en.wikipedia.org/wiki/Link-Local_Multicast_Name...

    The Link-Local Multicast Name Resolution (LLMNR) is a protocol based on the Domain Name System (DNS) packet format that allows both IPv4 and IPv6 hosts to perform name resolution for hosts on the same local link.

  7. DHCPv6 - Wikipedia

    en.wikipedia.org/wiki/DHCPv6

    The Dynamic Host Configuration Protocol version 6 (DHCPv6) is a network protocol for configuring Internet Protocol version 6 (IPv6) hosts with IP addresses, IP prefixes, default route, local segment MTU, and other configuration data required to operate in an IPv6 network.

  8. Explicit Congestion Notification - Wikipedia

    en.wikipedia.org/wiki/Explicit_Congestion...

    Without ECN, congestion indication echo is achieved indirectly by the detection of lost packets. With ECN, the congestion is indicated by setting the ECN field within an IP packet to CE (Congestion Experienced) and is echoed back by the receiver to the transmitter by setting proper bits in the header of the transport protocol.

  9. MAC filtering - Wikipedia

    en.wikipedia.org/wiki/MAC_filtering

    In computer networking, MAC address filtering is a network access control method whereby the MAC address assigned to each network interface controller is used to determine access to the network. MAC addresses are uniquely assigned to each card, so using MAC filtering on a network permits and denies network access to specific devices through the ...
