iftop must be run with sufficient permissions to monitor all network traffic on the interface; see pcap(3) for more information, but on most systems this means that it must be run as root. By default, iftop will look up the hostnames associated with addresses it finds in packets. This c...

Network File System (NFS)协议也是SUN公司设计的。顾名思义, NFS就是网络上的文件系统。 portmap的功能是维护一张进程与端口号的对应关系表,而它自己的端口号11是众所周知的 rpcinfo命令 telnet命令 从Wireshark看网络分层 传输层: 虽然名曰”传输层”,但它并不是把网络包从一个设备传到另一个,而只是对传输行...

查阅资料后发现,当无线网卡不支持或者没有设置为monitor mode时,无线网卡的驱动会自动把802.11 frame 转化为Ethernet frame后给kernel。官方解释为: If you‘re trying to capture network traffic that‘s not being sent to orfromthe machine running Wireshark or TShark, i.e. traffic between two or more ...
This lead to the development of a number of packet analyzers that will monitor the network assets to detect their anomalous behavior and misuse . In this paper we use wireshark as a packet analyzer which observed the communicating nodes and gathered data from them on an institute network . ...
Analyzing data packets is one way to monitor for problems in your network traffic or to detect connection problems. Wiresharkis a professional protocol analyzer aimed to help users in troubleshooting, analysis, software and protocol development, and education. All of the standard features you expect...
Sometimes, you can run the display interface command (or monitor the interface bandwidth on the NMS) to check whether the interface bandwidth usage is only 30% to 40%. If the value of the Output peak rate field is not large, you may ignore packet loss triggered due to the traffic ...
