[openib-general] mckey program

[amith rajith mamidala]

Hi,

I was checking the mckey.c program for IB.
I did some quick check and found that the  rdma_resolve_addr function
is invoking the cma_handler with erroneous event.

mckey: event: 1, error: -19

Is there any easy way to check what might be happening?

Thanks,
Amith

Hi Hal,

IPoIB interface is started. I can ping to other nodes using this. I
have also tried 224.0.0.1 but the error is still the same.
Are there any other set of programs which can make sure that the desired
set-up is in place.

Thanks,
Amith
