Yes, you're sure. As long as you don't touch udev. It's the same as with pci ethernet boards. Once you plugged it in, you'll have a persintent name for it no matter what unless you erase/alter your udev configuration.

You just substitute the interface assigned to freerunner instead of usb0 in all the examples, i can't see a problem. -- Be free, use free (http://www.gnu.org/philosophy/free-sw.html) software! mailto:fercer...@gmail.com ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
Re: usb0 vs eth0
i don't know which interface udev will assign to the neo.. for example when i connect it i get eth1, suddenly renamed to eth7 by udev, but am i sure it will always get eth7? I believe it depends on which distribution you run. Some distributions, like Debian, use a persistent-net-generator script which will always give a particular ethernet device a consistent name in /dev whenever it is plugged in. Personally, that drives me batty; I'm a tidy person and I don't like seeing my first ethernet card be named eth7 simply because I used several other cards in the distant past. But it's good for you in this case, your Freerunner should always have the same device name. The page http://wiki.openmoko.org/wiki/USB_Networking explain how to setup nat and routing, but all the examples use usb0. The problem is that each different udev installation will assign a possibly different interface name to the neo, so what should one do? setup nat and routing for all the interfaces being attached? seems strange.. I just would like to see an example, because it's not clear to me, and i think for many like me.. Yes, the usb0/eth1/eth7 problem is very annoying from a documentation point of view. It would be nice to have a single example on the wiki which people can use without editing. I don't have the answer to that one, but I'd love to see it if someone else does. --Ben P.S. If you're using Debian, you can check the file /etc/udev/rules.d/70-persistent-net.rules to see the mappings between the MAC address and device name. I believe OpenMoko devices always have a MAC address that starts with 00:1F:11 ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Re: usb0 vs eth0
The udev operation is simple. The net interface naming is normally
based on the MAC address and is stored in /etc/udev/rules.d/{something}
like 70-persistent-net.rules IF your distribution runs the persistence
script. Otherwise device naming is based on the order in which devices
are found by the kernel. If you load modules by hand, and you alternate
which you load first, then you would see the associated order change.
Mind you, if everything is done automatically by the kernel, the device
order can change if the kernel's sequence of loading drivers changes.
Every once in a great while that happens.
Here's my server's persistent net file:
Colt ~ # cat /etc/udev/rules.d/70-persistent-net.rules
# This file was automatically generated by the /lib64/udev/write_net_rules
# program run by the persistent-net-generator.rules rules file.
#
# You can modify it, as long as you keep each rule on a single line.
# PCI device 0x14e4:0x1659 (tg3)
SUBSYSTEM==net, ACTION==add, DRIVERS==?*,
ATTR{address}==00:1e:c9:2a:1c:64, ATTR{type}==1, KERNEL==eth*,
NAME=eth0
# PCI device 0x14e4:0x1659 (tg3)
SUBSYSTEM==net, ACTION==add, DRIVERS==?*,
ATTR{address}==00:1e:c9:2a:1c:65, ATTR{type}==1, KERNEL==eth*,
NAME=eth1
These are rules and they can be changed. If you want the 1c:64 device
to be named funkadiddle instead of eth0, you'd simply edit the file
and make the change of NAME=funkadiddle
If you alter the MAC address of your device, either by hand or on boot
such as in Qi etc, then it won't match if you have a rule set for the
old MAC address and it'll get the next available interface name.
So, simply set up your persistent-net rules file like you want and be
happy. Name your interfaces usbcable and wifi and set your
/etc/network/interfaces file to match if it pleases you so.

usb0 vs eth0
Hello. When I plug FR it appears as eth0 instead of usb0. According to http://www.linux-usb.org/usbnet/ I have to set the local assignment bit, 0x02 in the first octet, to ensure it still uses a name like usb0 not eth0. Do you know what does it mean? I'd like FR to always appear as usb0 so it wouldn't interfere with real ethernet interfaces. thanks, Max. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
