preseed with multiple network interfaces
Hello,
We have a bunch of machines with multiple NICs and eth0 isn't the one
that is connected to the network, but the installers tries to get a
link on eth0 and doesn't seem to try other interfaces. This is how the
PXE label looks like, I do have inteerface=auto, which should pick the
correct interface.
label squeeze
kernel debian-installer/squeeze/i386/linux
append vga=788 initrd=debian-installer/squeeze/i386/initrd.gz
auto=true priority=critical ramdisk_size=10800 root=/dev/rd/0 rw
url=example.com/d-i/squeeze/preseed.cfg interface=auto
netcfg/dhcp_timeout=60
This is the error I encounter
âââââââââââââââââââââ⤠[!!] Configure the network âââââââââââââââââââââââ

If I then drop to a shell, and look at dmesg, it sees all the
interfaces albeit with no link
~ # dmesg | grep eth

I then try to get a lease on the right interface and it works
~ # udhcpc -i eth4
udhcpc (v1.17.1) started
Sending discover...
Sending discover...
Sending select for 10.1.8.202...
Lease of 10.1.8.202 obtained, lease time 1800
On the kernel line I can try interface=eth4 and it works but we have a
bunch of machines and eth4 may or may not be right for different
machines. Why isn't interface=auto working correctly and what can I do
to make it work and automatically pick the right interface?
