Incremental update of software Because of moving to C #, a lot of things have been lost before. Now, starting from scratch, the first one is the automatic updating of the client. Previously, a simple search of the implementation of the relevant functions.

In ARP, there is a kind of scheme called Wuwei ARP. So what is the role of such ARP protocols? Next we will introduce it in detail. We hope that our introduction will help you understand this concept. Gratuitous ARP for no reason, GARP) ARP is also known as the Wuwei ARP protocol. The host sometimes uses its own IP add

middle and less than one hundred loops. Now I have made the cycle intermittent, but now I cannot continue to use it. what should I do? I don't know, but it will definitely put a lot of pressure on the server. It is obviously blocked. generally, sampling will continue in two days. First, you can calculate how long it takes to get blocked and then set the stop time. Use usleep or sleep for control. Or use

server software to do, and then proxy server to play the client request to complete, and then return the results to the client. Proxy server to analyze the contents of the packet, figure out what to do, and then as their own identity to "proxy" to complete the request, and send the results back to the client.such as HTTP, parse out the direction of the request, and then the identity of the proxy host, the

is not known, so the ARP broadcast packet is sent first, and in line fourth, 192.168.0.10 responds to 192.168.0.226 's request and tells 192.168.0.226 that its MAC address is 0 : 60:8:92:e2:d.In line five, 192.168.0.226 initiates a SYN request to 192.168.0.10, but in line sixth we can see that because the target host
