There are many open-source network monitoring tools available on the web for Linux operating systems. For example:You can use the command iftop to check bandwidth usage, netstat to view interface statistics reports, and other tools BANDWIDTHD, speedometer, nethogs, Darkstat, Jnettop, Ifstat, Iptraf, Nload and ntop and so on.But these tools are statistical card access data, if you want to find a like 360 security guard on Windows, can be in real-time s

Linux network traffic control tool-Netem Article 1: ConceptsNetem is a network simulation function module provided by Linux 2.6 and later kernel versions. This function module can be used to simulate complex Internet transmission performance in a LAN with good performance, such as low bandwidth, transmission latency, and packet loss. Many released Linux versions

Recently, the company's traffic suddenly increased, after inquiring about the room, a total of two server traffic is relatively large. One is the resources to provide download upload (normal), there is a club, Member login Center traffic is very large (not normal). All install a iftop tool to see the network card, as w

When developing network applications, it's always necessary to capture network traffic. windows CE has built-in sniffer tool, netlog for this purpose. it captures network traffics to a file that can be examined with Wireshark or network monitor. To enable it, we need to sele
