‘nmcli’ is a command-line tool for controlling NetworkManager and getting its status. Unlike ‘nmtui’, ‘nmcli’ doesn’t provide a text-based user interface, but it can be more powerful and flexible.<\/p>\n
Here’s how you can use ‘nmcli’ to show your network connections:<\/p>\n
# Show network connections with nmcli\nnmcli connection show\n\n# Output:\n# NAME UUID TYPE DEVICE\n# Wired connection 1 721591af-8c23-4f20-8d27-604b54bbf707 802-3-ethernet eth0\n<\/code><\/pre>\n
The output lists your network connections, including their names, UUIDs, types, and devices.<\/p>\n
Manual Network Configuration<\/h3>\n
You can also configure your network settings manually by editing configuration files. This method is more complex and requires a good understanding of networking, but it offers the most control.<\/p>\n
Here’s how you can manually configure a static IP address:<\/p>\n
# Open the network interface configuration file\nsudo nano \/etc\/network\/interfaces\n\n# Add the following lines:\n# iface eth0 inet static\n# address 192.168.1.100\n# netmask 255.255.255.0\n# gateway 192.168.1.1\n\n# Save and close the file\n\n# Restart the network service\nsudo service networking restart\n\n# Output:\n# 'networking stop\/waiting'\n# 'networking start\/running'\n<\/code><\/pre>\n
The output indicates that the networking service has been restarted successfully, and the new network settings are in effect.<\/p>\n\n\n\n\n\n\n\n
Method<\/th>\nAdvantages<\/th>\nDisadvantages<\/th>\n<\/tr>\n<\/thead>\n
