What permissions are required to configure an IP address in Linux?

Configuring IP addresses in Linux requires administrator "root" permissions, so that they have sufficient permissions to modify network settings: 1. Modify the network interface configuration file, edit the file, and change the IP address and subnet in it Mask, gateway and other information; 2. Use command line tools to configure the IP address.

To configure an IP address on Linux, you need to have sufficient permissions to modify network settings. Normally, only users with administrator (root) rights can make these changes.

Use root privileges to perform the following operations:

• Modify the network interface configuration file: The network interface configuration file is usually located in /etc/network/interfaces or / etc/sysconfig/network-scripts directory, depending on the Linux distribution you are using. You need root privileges to edit these files and change the IP address, subnet mask, gateway and other information.

• Using command line tools: You can use some command line tools to configure the IP address. For example, the ifconfig and ip commands can be used to view and configure the IP address of a network interface. When executing these commands in the terminal, you need to use the sudo command to obtain root privileges. For example, sudo ifconfig eth0 192.168.0.10 netmask 255.255.255.0 is used to set the IP address and subnet mask to the eth0 interface.

Please note that you should be extremely cautious when using root privileges for network configuration. Make sure you clearly understand the changes being made and only configure them for the appropriate network interfaces. Additionally, it is recommended to back up relevant configuration files before making important changes so that you can restore to a previous state in case an error occurs.
