Linux network secrets: Can one network port be bound to multiple IP addresses?

Linux network secrets: Can one network port be bound to multiple IP addresses? In Linux systems, one network port can be bound to multiple IP addresses. This technology is called multi-IP binding, which allows a host to have multiple different IP addresses on the same network port. Multi-IP binding has many practical application scenarios, such as providing virtual host services and achieving load balancing. This article will introduce how to configure a network port to bind multiple IP addresses in a Linux system, and attach specific code examples. In a Linux system, I

Analysis of the role and significance of i-node numbers in Linux

Analysis of the role and significance of i-node numbers in Linux

Analysis of the role and meaning of i-node numbers in Linux In the Linux file system, each file has a corresponding inode node, which is used to store metadata information of the file, such as file permissions, size, timestamp, etc. The i-node number is a number used to uniquely identify each inode node. Through the i-node number, the system can quickly locate the inode node and related information of the file, improving the operating efficiency of the file system. 1. The structure of the i-node number. In the Ext file system, the i-node number is a 32-bit number, ranging from

Learn more about Linux ldconfig

Linuxldconfig is a tool for dynamic link library management that can help the system find and load shared libraries at runtime. It is mainly used to update the system's dynamic linker runtime connection library cache to ensure that the program can correctly link to the shared library. ldconfig is mainly used in two aspects: one is to add and delete shared library paths, and update relevant information to the configuration file; the other is to regenerate the cache of the dynamic link library linker based on the path in the configuration file. Next we will introduce how to use ldconf
