***SPAM*** Re: [ofa-general] ConnectX IB HCA with Ubuntu 8.04

[Steven Truelove]

Yes, the DHCP server starts just fine.  The hardware address was pulled 
from the output of ifconfig on the client. Even if the hardware address 
was wrong, or I didn't list the host at all, the 'range' setting should 
ensure that an address is provided from the open pool.

There is output in the logs to indicate that there is no subnet listing 
for ib1 and eth0, and that it won't be listening on those interfaces.  
This implies that it is working on eth1 (where DHCP is tested working) 
and ib0 (where no log references to DHCPDISCOVER are made, even though 
the client is sending them).

That said, am I barking up the wrong tree entirely by even trying to 
make this work?  There are a few references to this being possible when 
I google for 'infiniband dhcp', and this is where I got the 
'always-broadcast on' setting from.  Apparently this is necessary.  But 
I couldn't find anything further to help me.

Thanks,

Steven Truelove
