". As a router manufacturer for Internet cafes, it has to do a lot of work to prevent ARP spoofing. 1. In the Broadband Router, all the IP-MAC of the PC into a static table, this is called the router IP-MAC binding. 2. Advise the network manager to set the static ARP information of the gateway on all the PCs in the Intranet, which is called the PC IP-MAC binding. The general manufacturer requires two jobs to do, called IP-MAC two-way binding. The method is effective, but the work is complicated

Implements a simple task system (task Scheduler) for multi-threaded task execution.Due to programming negligence, a thread multithreading created than the actual hardware line is used to perform the task.Part of the task execution, in the profiling tool, has been a time-consuming part.After discovering this problem, the whole execution time is almost half the same.Specific theoretical explanations can be seen in this article:http://www.codeguru.com/cp

port, the test is normal. Afterwards, I consulted related technical personnel. Before the fault occurred, the data traffic was very high. When the fault occurred, many data packets could not be forwarded normally, and the port would be suspended, the data traffic transmitted is very small. When it is disabled, the excess data is discarded, restarted, and normal data information is transmitted. Summing up the troubleshooting process above, we found that when a network fault occurs, we should che

network exceptions ARP attacks and unauthorized intrusion into wireless LAN are now a typical case of network exceptions. Due to the negligence of security settings and the lack of security protection in the future, a few malicious hackers have caused great harm to the important information and confidential data of the enterprise. ARP attacks may cause network IP conflicts, data loss and overflow, and even worse, network paralysis. These phenomena po

left and right structures cannot be flattened, and the right side is dropped down.In this case, there is a misaligned compatibility problem. In practice, because of our computing negligence, the difference is usually 1 px-2px, which won't be discovered by us, therefore, to eliminate misfit compatibility, you can start with width calculation. Example 2: 1px border instance in the left and right structureGenerally, the left and right structures have a
