Hi Stefan,

So i used the Shift+Control F2 to open second console.
on the busybox shell i use 3 commands:
ip link set dev eth0 down
ip link set dev eth0 address aa:bb:cc:dd:ee:ff
ip link set dev eth0 up
now the EtherNat has a valid MAC address (i randomized it from the example) but still D-I fails to DHCP. I need to fiddle around and find the problem here. Any hints welcome, i will make sure its not a hardware
issue in the meantime.
1)
you could try to work around the DHCP issue by setting a fixed IP address for the installation run:
This is what the D-I suggest after DHCP failure, too
ip address add 192.168.1.10/24 dev eth0
ok
ip route add default via 192.168.1.1
ip: RTNETLINK answers: Network is unreachable
where "192.168.1.10/24" is the IP address of the Falcon machine and "192.168.1.1" is the default gateway address (router).
2) what does "dhclient -v eth0" report?
I'm in a netinst busybox, dhclient is not installed
3) you could look at the DHCP traffic from the machine on a different console screen:
tcpdump -i eth0 port 67 and port 68
tcpdump is not installed, too
(not sure if tcpdump is available, else, because DHCP requests are broadcast messages in IPv4, running "tcpdump" on any other Linux or BSD machine in the same network segment should also show the requests and responses).
i find this line several times during DHCP attempt:
15:51:48.942029 IP 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP,
Request from de:97:6c:82:0d:3f (oui Unknown), length 300
de:97:6c:82:0d:3f is in fact the MAC that i set my EtherNat to.
There are tons of messages, not sure what to look for. Here a the first
few lines:
