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。 desc: "Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast Ethernet controller" network.hwaddr: 20:cf:30:8f:5a:cf vendorId: 10ec deviceId: 8136 subVendorId: 1043 subDeviceId: 8347 pciType: 1 pcidom: 0 pcibus: 1 pcidev: 0 pcifn: 0 [root@hvrhub ~]#
下面是查看网卡的网速:
[root@hvrhub ~]# ethtool eth0 Settings for eth0: Supported ports: [ TP MII ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full Advertised auto-negotiation: Yes Speed: 100Mb/s ------------------------------------>网卡速度 Duplex: Full Port: MII PHYAD: 0 Transceiver: internal Auto-negotiation: on Supports Wake-on: pumbg Wake-on: g Current message level: 0x00000033 (51) Link detected: yes
下面是查看网卡驱动的详细信息

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 ~]#
