Here is a question I got not so long ago.
Jermal, How do I go about finding the name and type of network card I have in my Linux installation?
First off, thanks for asking me. I know of a few ways and I’ll list them here. Short and simple. We have the the following commands: ip, ifconfig, lspci, dmidecode, lshw commands. Out of these I only use 3.
ifconfig and ip commands
root@websvr:~# ifconfig -a eth0 Link encap:Ethernet HWaddr 00:0c:29:f2:1f:55 inet addr:10.255.255.10 Bcast:10.255.255.255 Mask:255.255.255.0 inet6 addr: fe80::20c:29ff:fef2:1f55/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:1234097 errors:0 dropped:119 overruns:0 frame:0 TX packets:847638 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:177921015 (177.9 MB) TX bytes:359121554 (359.1 MB) Interrupt:18 Base address:0x2024
root@websvr:~# ip link show 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 3: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN qlen 1000 link/ether 00:0c:29:f2:1f:55 brd ff:ff:ff:ff:ff:ff

lshw command is another nice one also
root@websvr:~# lshw -class network *-network description: Ethernet interface product: 79c970 [PCnet32 LANCE] vendor: Hynix Semiconductor (Hyundai Electronics) physical id: 0 bus info: pci@0000:02:00.0 logical name: eth0 version: 10 serial: 00:0c:29:f2:1f:55 size: 1Gbit/s capacity: 1Gbit/s width: 32 bits clock: 33MHz capabilities: bus_master rom ethernet physical logical tp 1000bt-fd configuration: autonegotiation=off broadcast=yes driver=vmxnet driverversion=2.0.12.0 duplex=full firmware=N/A ip=10.255.255.10 latency=64 link=yes maxlatency=255 mingnt=6 multicast=yes port=twisted pair speed=1Gbit/s resources: irq:18 ioport:2000(size=128) memory:dc400000-dc40ffff
And when feeling a bit fancy you could toss in the lspci command with egrep
root@websvr:~# lspci | egrep -i --color 'network|ethernet'
02:00.0 Ethernet controller: Advanced Micro Devices [AMD] 79c970 [PCnet32 LANCE] (rev 10)
And… that is about it. I hope this answers your question
