Notes: please use the second argument of the template to provide more detailed indications. (Discuss in Talk:Rename network interfaces#)

Prerequisites

  • ifrename tool which is a part of the wireless_tools package.
  • udev package, which is already installed, of course.

Generic network interfaces

Option 1: udev

Create /etc/udev/rules.d/10-network.rules file with content like following:

 SUBSYSTEM=="net", ATTR{address}=="00:1e:58:48:33:08", NAME="lan"
 SUBSYSTEM=="net", KERNEL=="tap1", NAME="vpn"
 SUBSYSTEM=="net", KERNEL=="tap5", NAME="qemu"
Note: Make sure to use the lower-case hex values in your udev rules. It doesn't like uppercase.

Option 2: ifrename

Run ifrename directly

 ifrename -i eth0 -n lan

or create config file (/etc/iftab), for example:

lan		mac 00:0C:6E:C6:94:81
internet	mac 00:0C:6E:C6:94:82

and run

 $ ifrename -c /etc/iftab

PPP interfaces

Add into /etc/ppp/ip-up script the following lines:

 IF=$1
 /sbin/ifconfig $IF down
 /usr/sbin/ifrename -i $IF -n <NEWNAME>
 /sbin/ifconfig <NEWNAME> up

where <NEWNAME> is the new name for the ppp interface
