在Linux系统中,你可以使用ifconfig命令来查看网卡的状态。以下是具体的步骤:
ifconfig打开终端。
输入以下命令并按回车键:
ifconfig
你会看到类似以下的输出,其中包含了所有网卡的详细信息:
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.1.100 netmask 255.255.255.0 broadcast 192.168.1.255

RX errors 0 dropped 0 overruns 0 frame 0
TX packets 1234 bytes 98765 (96.4 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
如果你只想查看某个特定网卡的状态,可以在ifconfig命令后面加上网卡的名称。例如,查看eth0网卡的状态:
ifconfig eth0
UP(启动)、BROADCAST(广播)、RUNNING(运行)、MULTICAST(多播)等。ifconfig命令在某些现代Linux发行版中可能已经被ip命令取代。你可以使用ip addr show来查看网卡状态。ifconfig命令不可用,可以尝试安装net-tools包:sudo apt-get install net-tools # Debian/Ubuntu
sudo yum install net-tools # CentOS/RHEL
sudo dnf install net-tools # Fedora
通过以上方法,你可以轻松查看Linux系统中网卡的状态。
