A protocol is a standard method or format for communication between network devices. Protocols ensure that data are transferred whole‚ in sequence‚ and without error from one node on the network to

IPv6 Security Issues Internet Protocol v6 (IPv6) is replacing Internet Protocol v4 (IPv4). The need for IPv6 has risen to the forefront due to the depletion of IPv4 addresses. Security concerns and issues have slowed the adoption of the new protocol. Trade information is readily available for IPv6. A simple web search on the topic will lead you to trade magazine articles‚ books‚ white paper and even the government agency recommendations. The marketplace is brimming with “solutions” to IPv6 security

why MAC addresses for remote hosts are different than the MAC addresses of local hosts. Background / Scenario Wireshark is a software protocol analyzer‚ or "packet sniffer" application‚ used for network troubleshooting‚ analysis‚ software and protocol development‚ and education. As data streams travel back and forth over the network‚ the sniffer "captures" each protocol data unit (PDU) and can decode and analyze its content according to the appropriate RFC or other specifications. Wireshark is a useful

There are a few problems I would anticipate with using this combination of protocols. The first is if there is some sort of failure with the delivery of the sequence of data packets. As UDP is connectionless there isn’t a reliable order that the packets will arrive‚ one would assume this is why they are using stop and wait‚ to try and compensate for this issue. As a result‚ you may get some packets timing out and being resent by the server causing duplicate packets to be sent‚ all while awaiting

monitoring host or service uptime. The output from Nmap is a list of scanned targets‚ with supplemental information on each depending on the options used. Key among that information is the “interesting ports table”. That table lists the port number and protocol‚ service name‚ and state. The state is either open‚ filtered‚ closed‚ or unfiltered. Open means that an application on the target machine is listening for connections/packets on that port. Filtered means that a firewall‚ filter‚ or other network
