So I have been able to get ibping to work by using just 1 SM using the LIDs. However when using ibv_rc_pingpong and ib_read_bw, if I connect to the ib0 interface ip it doesn't seem to be able to connect to port 18515. However if I use the eth0 ip of the same node, the test works properly. Unfortunately, I need the ib0 ip to work for programs like netperf.
UFW has been disabled and there aren't any rules in iptables -L. Is it perhaps a TCP over IP configuration issue?
Thanks.
