Then I tried creating >/etc/modprobe.conf, with the line My temporary solution was to change the pattern for one of the devices. My problematic device is a rt2500-based PCI wireless card. I put the following in a file in /etc/modprobe.d/ : options rt2500 ifname=wlan%d That renamed my wireless to wlan0, instead of jumping between eth0 and eth1. Maybe something similar is possible with the drivers you're using? >alias eth2 eth1394 > >and as a result I could remove all the network modules and successfully >run "modprobe eth2", which had never worked before.However, the order >was still wrong after rebooting, then eth2 was my normal ethernet >interface, while eth1 had been "stolen" by the firewire driver again. > >So now I wonder how I can force my debian system to let me specify >which interfaces get which names during boot. I've seen that Debian policy is to have network interfaces show up as ethX so I'd very much like to know if there's a way to keep this naming and still control which physical device is mapped to which interface. /M -- Magnus Therning (OpenPGP: 0xAB4DFBA4) magnus@therning.org http://therning.org/magnus Software is not manufactured, it is something you write and publish.
