Turn from: http://www.cnblogs.com/bangerlee/articles/2545612.html Tcpdump can help us capture and save network packets, save the network packets can be used to analyze the network load, packets can be resolved by the tcpdump command, can also be saved as a suffix pcap files, using Wireshark and other software to view. Here are 9 examples of using tcpdump to illustrate the specific use of tcpdump. 1. For the specific mesh grab bag (-i option) When we execute tcpdump without any options, the t

verification set, and the rest is the training set. Use a fully-increasing decision tree in the training area of the training set. Then, for each subtree in the decision tree, we use the leaf nodes that contain all the training samples of the subtree, the result of the leaf node classification is "majority voting. We use a verification set to test the classification performance changes before and after replacement. If the classification accuracy increases after replacement, we have reason to th
