different, they are behind Nat; otherwise, they are behind Nat. To detect different types of NAT, the STUN Protocol defines message attributes and requires the server to have different actions, such as using different IP addresses and ports when sending responses, or changing ports. The STUN Protocol may be effective for Nat, but it is powerless for the firewall, because the firewall may not open the UDP port. Nat category Stun roughly divides NAT into four types: Full cone, restricted cone, po

Mysql transactions, concurrency issues, lock mechanisms, mysql transactions1. What is a transaction? A transaction is a combination of one or more database operation statements. It has four features: ACID. Atomicity Isolation: transactions are independent of each other and do not interfere with each other. Consistency: After the database changes its status correctly, the consistency constraints of the database are not damaged. Persistence: the transaction commit result, which is permanently stor

When the Docker Registry V2 comes out, it's really good to be simple and practical, but when you change port 5000 to something else, or use a domain name binding, it's a mistake. Here is a detailed record of the process of your own experience.First, the installation of Docker Registry V2 (distribution).Here I chose to use the official provided image to install, perhaps you will feel that it is easy, dismissive. However, for an OPS person, the attentio

different regions, there must be a solution to achieve interconnection between the two, so the atm lane technology came into being. By using LANE, the ATM network can simulate the work of the LAN, so that multiple LAN can be connected to the ATM network without any modification. ATM is responsible for bridging, which is completely transparent and seamless for users. It seems to work in a pure Ethernet environment, as shown in figure 2. The configuration process of LANE is complicated, and the
