For machine#1 my IPoIB  interface is

ib0       Link encap:InfiniBand  HWaddr
80:00:00:03:FE:80:00:00:00:00:00:00:00:00:00:00:00:00:00:00
          inet addr:140.221.37.32  Bcast:140.221.37.255  Mask:255.255.255.0
          inet6 addr: fe80::211:7500:ff:d802/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:65520  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:1 errors:0 dropped:5 overruns:0 carrier:0
          collisions:0 txqueuelen:128
          RX bytes:0 (0.0 b)  TX bytes:68 (68.0 b)

For machine#2 my IPoIB interface is

ib0       Link encap:InfiniBand  HWaddr
80:00:00:02:FE:80:00:00:00:00:00:00:00:00:00:00:00:00:00:00
          inet6 addr: fe80::211:7500:ff:d7f2/64 Scope:Link
          UP BROADCAST MULTICAST  MTU:65520  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:1 errors:0 dropped:21 overruns:0 carrier:0
          collisions:0 txqueuelen:128
          RX bytes:0 (0.0 b)  TX bytes:68 (68.0 b)

Can you please tell me what the IPoIB IP addresses are for these two
machines ? Also I do not know the IPv4 address for ib0 of machine#2 is not
showing up ?
