Iptraf is a ncurses based IP LAN monitoring tool that generates a variety of network statistics, including TCP information, UDP statistics, ICMP and OSPF information, Ethernet load information, node statistics, IP checksum errors, and other information. Its ncurses user interface also saves users from the Dream nightmare of command line options. Function An IP

is, the response-based solution. What's worse, this problem usually comes from complaints from end users, which undoubtedly raises questions about the work of the IT department. In addition to the obvious public relations, this response-based problem solution is very inefficient. If the problem is detected early, it takes only a few minutes to solve the problem, but if it is found late, it will waste more time. For example, if it is found early, the log can solve the problem of insufficient dat

, which can be used for public network access by the streaming media server of LAN. From the effect of monitoring software display feedback, the quality is barely possible. Note that the IP address of the test end is 192.168.1.13 and the IP address of the streaming media server is 17.1.2.2. As for why streaming media data is transmitted between 53 and 13, that is the role of the stun protocol. When stun

obtained through business monitoring data. For example, by monitoring the maximum amount of traffic and maximum IO in the data, the packet size can be roughly evaluated, which is, of course, imprecise.Because the factors that determine network performance are part and configuration related, parameters such as buffer size can be changed in the test to see if the

Now that the network connection has been established, the historical mission of the listener process has been completed.A different angle to understand:ORCL is the name of the service we use to connect to the remote database, but eventually it must be translated into a connection string such as Ho
