ifconfig Command Options Used With DHCP Client. The ifconfig command enables you to:. Start the DHCP client – The command ifconfig interface dhcp start initiates the interaction between the DHCP client and DHCP server to obtain an IP address and a new set of configuration options. May 06, 2020 · That's ifconfig. It's safe, it's familiar, and you feel comfortable using it. The ifconfig command still has a lot to offer its users. Whether its displaying network settings, configuring an IP address or netmask, creating aliases for interfaces, or setting MAC address, ifconfig can handle it. Using ifconfig. If you want to add a secondary IP address to a NIC already in use in Linux, and have that change only temporary. Enter this command: ifconfig [nic]:0 [IP-Address] netmask [mask] up An example is shown below. ifconfig eth0:0 192.168.1.2 netmask 255.255.255.0 up You need to be root in order to execute that command. Using ip command Additional parameters with ifconfig Let’s write a command using ifconfig which will change the IP address of the network ‘enp0s3’ to 192.168.0.1 and also changes the subnet mask 255.255.255.0: sudo ifconfig enp0s3 192.168.0.1 netmask 255.255.255.0 Change IP Address using ifconfig.

However, you should still be able to use the “ifconfig” to change your IP address. $ which ifconfig /usr/sbin/ifconfig Is there a way in Linux, using C code, to get the same information that "ifconfig eth0" would return? I'm interested in things like IP address, link status, and MAC address. Here's sample output
