How xti9erOSSEC checks netstat rookit is: Use netstat to view the port and bind this port for comparison.
If the port cannot be bind, it indicates that the port is occupied. If netstat does not find this port, it indicates that netstat is replaced by rootkit.
The idea is good. However, the difference between the two ca
Server slowness may be caused by many events, such as incorrect configurations, scripts, and poor hardware. But sometimes it may be caused by a flood attack on your server using DoS or DDoS.
DoS attacks or DDoS attacks are attacks that try to make machines or network resources unavailable. The attack target websites or services are usually hosted on Anti-DDoS servers such as banks, credit card payment network management, and even root domain servers. DOS attacks usually force the target to rest

Many linux services are related to the network. When the service cannot be called, the startup port is occupied, or the firewall is blocked, you need to query network problems, the netstat command only uses one or two parameters.
Common options:
-A (all) shows all options. LISTEN is not displayed by default.
-T (tcp) only displays tcp-related options
-U (udp) only
The netstat command is used to display statistics related to IP, TCP, UDP, and ICMP protocols, and is typically used to verify the network connectivity of each port on the machine. Netstat is a program that accesses the network and related information in the kernel, and it provides reports on TCP connections, TCP and UDP snooping, and process memory management.If your computer sometimes receives datagrams t

ObjectiveUsing the centos6.5 system's own netstat,grep,watch and other commands to analyze the network connection status requires a deep understanding of the concept of TCP finite state machine.At the same time, this is in addition to using powerful professional third-party protocol analyzers, such as Wireshark, the most effective way.One of the purposes of writing a blog is to tell you that you do not use third-party tools such as Wireshark, you can

Netstat is used to display statistics related to IP, TCP, UDP, and ICMP protocols, and is typically used to verify network connectivity across local ports.
If our computers sometimes receive datagrams that cause error data deletion or failure, we do not need to be surprised that TCP/IP can allow these types of errors and can automatically send datagrams again. But if the cumulative number of error cases accounts for a significant percentage of the
