Here’s how to rename your network card in Ubuntu
- Get your ethernet card MAC address:
ifconfig | grep HWaddr
keep it handy (open a new Terminal window for following steps) cd /etc/udev/rules.d- backup your file:
cp 70-persistent-net.rules 70-persistent-net.rules.bak - edit your file:
sudo nano 70-persistent-net.rules - very carefully type:
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="xx:xx:xx:xx:xx:xx", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
where the xx:xx:xx are your MAC HWAddr from Step 1
Type this all as one big long line, then save and exit. - edit /etc/network/interfaces to refer to eth0 instead of p1p1 or whatever [thanks Konstantin]
- reboot
- login and type
ifconfigto confirm your network adapter is at eth “
