Question How does ifconfig know... ?


Hey,
when I run:
ifconfig eth0 up
how does ifconfig know what eth0 is? It's just an alias for an interface, right? I want to bring up a different interface, but it doesn't have an alias (such as eth0). This interface is my USB modem (Alcatel SpeedTouch), and eth0 is my network card.

I have a program (modem_run), which loads the driver for my USB modem. After running that, ifconfig shows an interface named ppp0, which is my USB modem. Then I can run pppd to connect to the internet, works fine. But I want to use the new 2.6 kernel, which comes with a driver for my modem. I won't need modem_run to load it anymore. But I don't know how to bring up the interface! It says ppp0 is an unknown interface, so I'm guessing I have to tell it what ppp0 is somehow? How do I do that?

here's where to load drivers:

/etc/modules.conf

in there, you will find aliases for eth interface and many other things..

But the drivers are not modules, they are compiled into the kernel.
I did find the line:
alias eth0 dmfe
in both /etc/modules.conf and /etc/modprobe.conf, so I tryed adding:
alias ppp0 speedtch
but it didn't do anything. Tryed compiling the drivers as modules, still nothing. I removed both the eth0 and ppp0 lines from /etc/modules.conf and /etc/modprobe.conf, and eth0 still works So that definately doesn't have anything to do with it =(.
