Sometimes you wish to allocate more friendly names to the ethernet cards in ubuntu for better administration of the linux. In this tutorial you can learn how to do that.
Step 1: Issue “sudo ifconfig” command to check the current names of your ethernet cards
eth0 Link encap:Ethernet HWaddr 00:f0:4f:3f:f6:f7
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0

Step 2: Edit file “sudo nano /etc/udev/rules.d/70-persistent-net.rules”
# PCI device 0x10ec:/sys/devices/pci0000:00/0000:00:1c.1/0000:02:00.0 (r8169)
SUBSYSTEM==”net”, ACTION==”add”, DRIVERS==”?*”, ATTR{address}==”00:e0:4c:36:06:c7″, ATTR{dev_id}==”0x0″, ATTR{type}==”1″, KERNEL==”eth*”, NAME=”eth0″
# USB device 0x0846:0x4260 (usb)
SUBSYSTEM==”net”, ACTION==”add”, DRIVERS==”?*”, ATTR{address}==”00:1b:2f:cd:fb:c5″, ATTR{dev_id}==”0x0″, ATTR{type}==”1″, KERNEL==”wlan*”, NAME=”wlan0″
Step 3: Change the parameter NAME to whatever you wish like.
Step 4: Reboot the system
That’s all you need to do.
