I am trying to configure my fedora box to bring up ib0 on startup. Unfortunately it is failing, saying that the IP address is already taken on the network -- no matter what IP address I use. I traced this down to the fact that the ifup script uses "arping" to test this condition. It appears arping is failing something like this:
# arping -c 2 -w 3 -D -I ib0 192.168.0.62
ARPING 192.168.0.62 from 0.0.0.0 ib0
Sent 2 probes (2 broadcast(s))
Received -1 response(s)
where I can ping:
# ping 192.168.0.62

I have looked at the arping code, and it seems to be crafting the packet
correctly, even using 32 in the type field, so I am a bit befuddled as
to why this isn't working.
Any ideas?
