[openib-general] ping between IB interfaces

[vinh nguyen]

Hi,

I downloaded and installed ibal1-285 from
sourceforge.net. I followed the INSTALL.txt guide,
I've got ipoib and opensm running but when I tried to
"ping" between two nodes I got "Destination Host
Unreachable".

I'm running the modules on kernel 2.4.20. I have two
Mellanox HCA cards, and I connect them directly to
each other on port 1. I ran opensm on one node and
ipoib on both nodes. When I do "ifconfig -a", I was
able to see the devices ib010 on both nodes. Then, I
issued "ifconfig ib010 192.168.0.1" on one node, and
"ifconfig ib010 192.168.0.2" on the other node. When I
do a "ifconfig ib010" I got:

node 1:

ib010     Link encap:UNSPEC  HWaddr
FF-FF-00-00-00-00-00-00-00-00-00-00-00-00-00-00
          inet addr:192.168.0.1  Bcast:192.168.0.255

          RX bytes:1344 (1.3 Kb)  TX bytes:1440 (1.4

node 2:

ib010     Link encap:UNSPEC  HWaddr
00-00-00-18-FE-80-00-00-00-00-00-00-00-00-00-00
          inet addr:192.168.0.2  Bcast:192.168.0.255

          collisions:0 txqueuelen:128
          RX bytes:1344 (1.3 Kb)  TX bytes:1440 (1.4
Kb)


I also followed the INSTALL.txt to add ipoib IP
addresses to /etc/host file.

127.0.0.1	infiniband4	localhost.localdomain	localhost
	
192.168.0.1	infiniband3-ib0
192.168.0.2	infiniband4-ib0

192.169.0.1	infiniband3-ib1
192.169.0.2	infiniband4-ib1


Did I miss something? I'm new to infiniband, and I've
been reading the mail archive on sourceforge.net forum
but still not able to figure out what the problem is.
Some of you had expressed the same problem in the
past, I would appreciate if you can tell me how you
solved the problem and help me solve mine. Thanks in
advance.

Vinh Nguyen.
