Thanks, DavidThe SXXscript 'starts' the script KXXscript stops it. These links are run in numerical order of the XX.This script only runs 'ifup -a', as far as I can tell. Ifup won't log which devices it upped. Furthermore, 'ifup -a' never ups my usb nets eth1 and eth2 when I ssh in, down eth1 and eth2 and then issue 'ifup -a'. However, one of them is always up when my system finishes booting. How can that be?
Hmm! from man ifup'-a, --all If given to ifup, affect all interfaces marked auto. Interfaces are brought up in the order in which they are defined in /etc/network/interfaces.'
man interfaces'Lines beginning with the word "auto" are used to identify the physical interfaces to be brought up when ifup is run with the -a option. (This option is used by the system boot scripts.) Physical interface names should follow the word "auto" on the same line. There can be multiple "auto" stanzas. ifup brings the named interfaces up in the order listed.
Lines beginning with "allow-" are used to identify interfaces that should be brought up automatically by various subsytems. This may be done using a command such as "ifup --allow=hotplug eth0 eth1", which will only bring up eth0 or eth1 if it is listed in an "allow-hotplug" line. Note that "allow-auto" and "auto" are synonyms.'
So ifup -a will only bring up all the interfaces marked 'auto' as you have discovered.
allow-hotplug passes the task of bringing up of the interface to udev (as this now incorporates hotplug) so /etc/init.d/udev is the script that starts the deamon.
As to why this doesn't work and the 'auto' does, its probably something to do with the udev rules used to identify the interfaces. I don't have usb interfaces and am not a udev expert so I don't know how much more help I can be :)
