How to check which network cards are available in Linux: 1. Use the "ifconfig -a" command to check; 2. Use the "cat /proc/net/dev" command to check; 3. Use "lspci | grep -i ' eth'" or "lspci | grep -i net" command to view.
#The operating environment of this tutorial: linux5.9.8 system, Dell G3 computer.
Method 1: Useifconfig -a
ifconfig : The most commonly used command to configure and view network interface information. Executing this command on the server will get the content below. You can see multiple devices and device status and information in the following content.
[root@xuegod65 ~]# ifconfig -a eth0 Link encap:Ethernet HWaddr 00:0C:29:04:08:91 inet addr:192.168.1.250 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::20c:29ff:fe04:891/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:14454 errors:0 dropped:0 overruns:0 frame:0 TX packets:961 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:1174828 (1.1 MiB) TX bytes:112979 (110.3 KiB) eth1 Link encap:Ethernet HWaddr 00:0C:29:04:08:9B inet addr:192.168.240.1 Bcast:192.168.240.255 Mask:255.255.255.0 inet6 addr: fe80::20c:29ff:fe04:89b/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:112 errors:0 dropped:0 overruns:0 frame:0 TX packets:90 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:9334 (9.1 KiB) TX bytes:8366 (8.1 KiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)
Method 2: Usecat /proc/net/dev
[root@xuegod65 ~]# cat /proc/net/dev Inter-| Receive | Transmit face |bytes packets errs drop fifo frame compressed multicast|bytes packets errs drop fifo colls carrier compressed lo: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 eth0: 1190124 14635 0 0 0 0 0 0 119423 999 0 0 0 0 0 0 eth1: 9334 112 0 0 0 0 0 0 8366 90 0 0 0 0 0 0
method 3: Uselspci | grep -i 'eth'orlspci | grep -i net
to list each pci bus After filtering through grep, you can get the network card device list
[oracle@mori ~]$ lspci |grep -i 'eth' 02:01.0 Ethernet controller: Intel Corporation 82545EM Gigabit Ethernet Controller (Copper) (rev 01) 02:06.0 Ethernet controller: Intel Corporation 82545EM Gigabit Ethernet Controller (Copper) (rev 01) [oracle@mori ~]$ lspci | grep -i net 02:01.0 Ethernet controller: Intel Corporation 82545EM Gigabit Ethernet Controller (Copper) (rev 01) 02:06.0 Ethernet controller: Intel Corporation 82545EM Gigabit Ethernet Controller (Copper) (rev 01)
