following is a separate attack:1. check whether there are different MAC addresses in the packets with the same IP address. If so, determine that the user shares the internet. Attack handlingThe method is to change the MAC address of each machine to the same. The modification method is as follows:First, obtain the MAC address of the Local Machine: the MAC address is the physical address that is fixed in the serial EEPROM on the NIC, usually with 48-bit length. ToThe ingress switch implements pac

This is an interview question for someone in early October. After-sales position: Senior Network Engineer. The interviewer is a three-member CCIE. The interview lasted more than two hours, and he was very impressed. Now this offer is basically determined, and the subject is still considering situations such as treatment and work pressure before deciding whether to accept this offer. the subject also posted

information in the unit time is determined;(9) in the analog channel, the bandwidth is w=f1-f2 by the formula; the bandwidth of the digital channel is the maximum data rate that the channel can reach;3. BER: In noisy channels, the increase of data rate means that the concept of error in transmission increases; the probability of error in transmitting bits is expressed by bit error rate:**P=N1 (number of faulted digits)/n2 (number of bits transmitted)* * In the computer communication

For example, in project development, we need to specify the user's gender, at this time can be defined as a constant sex, assigned to "male", in the need to specify a user-specific place to call this constan

Before you change your job, you always want to test. Then I thought of the soft test. There is a remote training session on the 51cto to enroll. Cost 600 yuan, think quite cheap, buy an insurance, after all do not know what to test.Results The training course is very reliable, the teacher is very patient, the question is very deep will answer, but also with the students to discuss thinking, willing to admit their mistakes, and even to answer some and test and irrelevant issues. It's really very
