[ofa-general] Problem running SDP apps using OFED 1.2

Does "lsmod | grep sdp" report SDP is loaded on both machines?
I would then use strace with the client to watch the socket system calls
happening, to make sure the client is trying to use SDP.

1.2
I restarted openibd and now my interfaces are up.

I am able to "ping 140.221.37.46" from machine#2.

But sockets over SDP still gives me the same "Network

Can you ping between the two nodes using the IPoIB IP

Hi Dotan,
ifconfig shows up
ib0 Link encap:InfiniBand HWaddr

does this mean that the apps would now use IPoIB
? How do i tell when IPoIB is working and when it isnt ? Because I
assume when it isnt it would default to Ethernet ?
It will be great if I can get this cleared.
Thanks

(this way you can be sure that IPoIB is
working and SDP should work)
