Q. My Ethernet aliases are randomly switched and they are bound to the wrong interface. My eth0 became eth1 and eth1 become eth0. This is causing all sort of trouble for services and firewall configurations. How do I swap back and make sure Ethernet aliases works correctly under CentOS Linux server?
DEVICE name : eth0
IP ADDRESS : 10.10.29.66
NETMASK : 255.255.255.192
ROUTER IP: 10.10.29.65
How do I setup a static IP address under a Ubuntu Linux 14.04 or 16.04 LTS server?
