The loop has a great impact on the network. Spanning Tree protocol is a good solution to this problem.The idea of spanning a tree protocol topology is that, regardless of the physical connection between switches, the switch can automatically discover a network with no loop topology, and the network of the logica

Now that Cisco Nat is flexible, Can Linux implement it? The answer is yes! Linux netfilter is super flexible, and Linux Nat is not flexible because the iptables program is not flexible. xtables-Addons rawnat has taken an important step towards static Nat, iptables restricts the development of static Nat in Linux! So I put aside iptables, first implemented the kernel module based on Netfilter, and then used procfs as the user interface to see how to im
