Linux advanced routing, a policy-based route that is more powerful and flexible than traditional routing, can not only forward paths based on destination addresses but also select routing forwarding paths based on message size, application, or IP source address so that system administrators can easily:1, control the bandwidth of a computer.2, control the bandwidth to a computer3. To help you share your bandwidth fairly4, protect your network from Dos attacks5, protect your Internet from your cus
in your code without having to define them at the beginning of the function. And you can initialize the structure, such as the following code slice:
while (1) {
int key_value = Read_key ();
}
Deviceinfo_typedef Tdeviceinfomem = {
. mac_addr = {0x84, 0x39, 0xBE, 0x90, 0x00, 0x00},

. netmask = {255, 255, 252, 0x00},
. Gateway = {Ten, 3, 254},

The example in this article describes how the go language intercepts strings by byte. Share to everyone for your reference. The implementation methods are as follows:
Copy Code code as follows:
Intercept strings by byte Utf-8 not garbled

To this end, we can divide several computers into different subnets Based on the floor or work department, and require different subnets to use different VLANs; considering that computers in different VLANs cannot communicate with each other directly, we also need to set routes to ensure that each VLAN can communicate with each other, in this way, the transmission stability
