查看网卡信息

# dmesg | grep -i eth

vi /etc/sysconfig/network-scripts/ifcfg-eth0

用这个可以看到网卡的信息

直接输入dmesg可以看到开机检测到硬件信息

cd /proc目录下

然后根据你的需求察看不同的文件，可以看到你要的东西

lspci | grep Ethernet

如果没有lspci,需要先安装

dmesg |grep -i eth

这样就可以了。

如何在Linux/centos下查看网卡型号，如何查看主板型号，CPU/显卡信息，硬盘型号等硬件信息

查看网卡型号

[root@www.ctohome.com]# lspci | grep Ethernet

00:19.0 Ethernet controller: Intel Corporation 82567V-2 Gigabit Network Connection
