The computer network card can not get the IP address of such problems, you may try to change the network card working mode to solve. Expand network adapters in Device Manager, double-click the NIC driver flag, and then switch to the advanced option to change the NIC operating rate mode from automatic mode to 10Mbps Full-duplex mode in the properties. If you still do not solve the problem, it is likely that

Tags: Linux network card eth1 How to change to eth0Normally, the first time that Linux recognizes a NIC is eth0, and the second one is eth1. Sometimes we use the virtual machine cloning technology after the network card information will change, the newly cloned virtual host network card name may become eth1. No matter how we modify it, this is a problem when we use N virtual machines for ha-heartbeat experiments.In this case it is because the replicat
