ethernet is not a point-to-point network even if there are only 2 hosts on
the network

I think on a point-to-point network, you won't have a DR or a BDR.
thanks,

Subject: IP OSPF neigh in INIT/DROTHER state
I got two routers connected to each other via an ethernet
hub. R2 and R5.
This is the show ip ospf neigh on r 2 and show ip ospf int e 0 on
both
routers. Both routers are electing each other as the DR and
no BDR (they
do
not see each other).
Why are these two guys not electing a DR?
Why is R5 not even seeing R2 as a neighbor?
