Hi
    I checked the code and it seems there was indeed a problem with that.
I changed the code and now it posts the connect request and does not
get any event. The ep_status is DAT_EP_STATE_CONNECT_PENDING.
I am trying now with dapltest to see if it is a problem with my server
(netapp filer NFSoRDMA) or the Open IB stack.

Thanks for your help. If you have any idea about some special configuration
required for the connection, I would really appreciate your help. Is 
there any
way to see the requests similar to tcpdump?

Thanks
