Hi,

I managed to setup networking with a self build core networking. Both Intel e1000 cards in my machine are recognized and
 it's possible to set up IP addresses and ping other machines.

The following problems arose:

* no information can be set/read via sysctl:

# sysctl -w net.inet.ip.forwarding=1
sysctl: top level name 'net' in 'net.inet.ip.forwarding' is invalid

# sysctl -a
#

* netstat and sockstat return with errors:

# netstat
netstat: sysctlnametomib: net.inet.tcp.pcblist: Invalid argument
# sockstat
sockstat: sysctlnametomib: net.inet.tcp.pcblist: Invalid argument

* ifconfig spits out various errors/warnings:

# ifconfig -a
lo0: flags=8009<UP,LOOPBACK,MULTICAST> mtu 33212
        capabilities=7<IP4CSUM,TCP4CSUM,UDP4CSUM>
        enabled=0
ifconfig: SIOCGIFADDRPREF: Invalid argument
        inet 127.0.0.1 netmask 0xff000000
en0: flags=8c43<UP,BROADCAST,RUNNING,OACTIVE,SIMPLEX,MULTICAST> mtu 1500
        capabilities=7<IP4CSUM,TCP4CSUM,UDP4CSUM>
        enabled=0
        address: 00:04:23:c3:91:0a
ifconfig: SIOCGIFADDRPREF: Operation not supported
        inet 192.168.1.100 netmask 0xffffff00 broadcast 192.168.1.255
en1: flags=8c43<UP,BROADCAST,RUNNING,OACTIVE,SIMPLEX,MULTICAST> mtu 1500
        capabilities=7<IP4CSUM,TCP4CSUM,UDP4CSUM>
        enabled=0
        address: 00:19:d1:29:f6:9c
ifconfig: SIOCGIFADDRPREF: Operation not supported
        inet 192.168.2.100 netmask 0xffffff00 broadcast 192.168.2.255

Am I missing something important? The following tasks are running:
