Re: Packet Filter: how to keep device names on hardware failure?

[Harald Dunkel]

PS: Below is the code, if anybody is interested. Should be run
before /etc/netstart. To use it you should create a file

        /etc/ifconfig.xx:xx:xx:xx:xx:xx

for each network device ("xx:xx:xx:xx:xx:xx" is the MAC
address). Each line is run with

        ifconfig if $line

Here is a sample

        inet 172.19.96.1/24
        inet alias 172.19.97.1/24
        group int_if

Comments are welcome.
