the destination IP address, Ask the other party to return a packet of the same size to determine whether two network machines are connected, how much delay. Ping refers to end-to-end connectivity, which is often used as a check for usability, but some virus Trojans force a large number of remote ping commands to preempt your network resources, causing the system to slow down and slow down. Ping intrusion is strictly forbidden as a basic function of most firewalls to provide users with a choice.

generally used to display all connected ports and are represented by numbers. The function of the netstat command is to display network connections, routing tables, and network interface information to let users know which network connections are in operation.[1] When used without parameters, Netstat displays the active TCP connection. Netstat (option)Options-A or--all: Displays the socket;-agroups: Displays the multi-broadcast feature group members list;-H or-- Help: online assistance;-I or--

Role:A router, gateway that looks at which IP addresses the packet passed through during transmission.Working principle:First send a TTL of 1 UDP packets to the remote host, according to the protocol, the router receives the packet, the TTL value minus 1, when the TTL is 0, the router discards the packet, and sends the sender back an ICMP packet, the packet contains the router's own IP address. Similarly, the host that executes the traceroute host con

telnet : The Telnet protocol is a member of the TCP/IP protocol family and is the standard protocol and main way of Internet remote Login service. It provides users with the ability to perform remote host work on the local computer. Use the Telnet program on the end user's computer to connect to the server. End users can enter commands in the Telnet program that run on the server as if they were entered directly on the server's console. The server ca

, for example, whether there is congestion, whether the data transmission path is reasonable, and whether there is packet loss. However, if the network topology between the client and the server is complex, it will still be difficult to handle. Even if the cause of the problem is identified, it is difficult to find out where the problem occurred. Therefore, the traceroute ip command has certain limitations. It is easy to find out the cause of the prob

The last one said we had a preliminary business analysis and got the user, business use case and business scenario model. These three outcomes form the basic requirements framework and delineate the scope of the business. A baseline should be made at this time. Of course, the first baseline contains very thick content, and there is more work to be done to achieve the full requirements. This article is about the detailed requirements process and outpu

However, the MapReduce programming model has its own limitations. Its single input, two-stage data flows in strict, and the level is too low. For example, you would have to write custom code even for the most common operations. As a result, many programmers feel that the MapReduce framework is uncomfortable to

The STS and Virgo environments have been configured above, and the Virgo server can be successfully run. Next we will use STS to build several projects. We simulate an example of registration. In our actual case, data is sometimes written to the database, written to a file, or written to the memory, which is convenient for different operations. This example may not completely explain the problem, but it is enough to explain how to build a project th
