The reason seams to be a completely broken configuration of dhclient.conf
resulting in several problems. Among them that two boxes get the same IP
address. Both your BSD and you Linux box have 192.168.1.33.

The problem is probably you sending that name "localhost" which should
never have any other address than 127.0.0.1. Why did you play with the
settings anyway? Normally a dhcp-client works right out of the box. I have
never had to change any of the configurations - ever.
