;Default:Detect_beat_func = detect_beat_auto;Ifplugd uses detect_beat_auto in the default configuration. In fact, this function is to try the above functions one by one. interface_detect_beat_ethtool and interface_detect_beat_mii. The status of the network card can be obtained through these four methods, but the implementation is different.The following describes their implementation:Method 1: interface_det

Tags: localhost out desktop file default none Ted Fat forIn Linux network interface configuration file is generally in a file, set the interface, device name, scheme name, IP address acquisition mode, whether to automatically assign IP when the boot, and so on, all of these settings are in the configuration file/etc/sysconfig/
Managing Ethernet Connections The network interface uses a sequential identity: eth0, eth1, and so on. The network interface can be set to use aliases (aliases), the alias is labeled: Eth0:1, Eth0:2, which is called Network Sub-interfa
, the packet is sent directly to its cpu. from this we can see that the ping loop return address does not mean that the network card address can be pinged. Therefore, do not ping 127.0.0.1 to check whether the network card is good or bad. This will not work. Let's take a look at the router example. for example, routers
