linux系统查看网卡命令_linux如何配置网卡

rhel 内核版本号信息：

[root@hvrhub ~]# uname -a

Linux hvrhub 2.6.18-308.el5 #1 SMP Fri Jan 27 17:17:51 EST 2012 x86_64 x86_64 x86_64 GNU/Linux

查看网卡的驱动。制造商等信息：

[root@hvrhub ~]# kudzu –probe –class=network

例如以下命令能看出来是不是集成网卡？—有待验证。

[root@hvrhub ~]# dmidecode | sed -n ‘/net/,+5p’

Type: Ethernet

Status: Enabled

Description: Onboard Ethernet ——————->这个意思是不是说这是集成网卡？有机会的话，弄个pci网卡上去，再运行此命令看看是啥输出。

Handle 0x0020, DMI type 11, 5 bytes

OEM Strings

以下的命令也能看出网卡控制器的制造商信息。

[root@hvrhub ~]# lspci | grep Ethernet

01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast Ethernet controller (rev 02)

[root@hvrhub ~]#

查看网卡网速的另外一个命令：

[root@testb .vnc]# ethtool -i eth0
