Bind an IP address to a Linux dual-nic. The actual task is to use two NICs as one. Using the same IP address is a better and faster service. Here we use RHLE3 to experiment on this job. Bind an IP address to a Linux dual-nic. Here we will introduce the specific practices. The following section describes some problems. NIC) The binding technology helps to ensure h

One machine may have more than one Nic, but each Nic has only one MAC address, and each Nic may have multiple IP addresses. For example, in a normal laptop, there will be two types of wireless Nic and wired NIC (Network Interface). Therefore, if you want to obtain the IP and
