linux下查看网卡信息的命令

rhel 内核版本信息：

[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
-
class: NETWORK
bus: PCI
detached: 0
device: eth0
driver: r8169 ---------------->这是驱动名称，下面的modinfo命令会用到该驱动名称。

[root@hvrhub ~]# 

下面是查看网卡的网速：

[root@hvrhub ~]# ethtool eth0
Settings for eth0:

如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，再执行此命令看看是啥输出。
Handle 0x0020, DMI type 11, 5 bytes
OEM Strings

下面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
driver: r8169
version: 2.3LK-1-NAPI
firmware-version:
bus-info: 0000:03:00.0
[root@testb .vnc]# ethtool -i eth1
driver: r8169
version: 2.3LK-1-NAPI
firmware-version:
bus-info: 0000:04:06.0
[root@testb .vnc]#
