What permissions are needed to configure an IP address in Linux? What actions can be performed?

Configuring the IP address in Linux can be done through commands or graphical interface. So what permissions are needed to configure an IP address in Linux? Let’s take a look at the introduction.

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

Using root privileges, you can perform the following operations:

Typically, the configuration files for network interfaces are located in different directories, such as /etc/network/interfaces or /etc/sysconfig/network-scripts, depending on the Linux distribution used. Editing these files requires root privileges to modify network information such as IP address, subnet mask, gateway, etc.

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.

Be careful when configuring the network, especially when using root privileges. Make sure you understand the changes and only configure the correct network interfaces. In addition, it is best to back up relevant configuration files before making important changes so that you can restore to the previous state if something goes wrong.
