Check your firewall settings on the 192.168.0.1 box.  Can you access the administrative share on each node from the other (\\192.168.0.1\c$, and \\192.168.0.2\c$?)

You probably have OpenSM running on this node, yes?  You can't run osmtest on the same port where OpenSM is running.

Don't know the details of this tool, maybe it's running into the same problems as osmtest?  Try running OpenSM on the other node and see if the problem follows the SM or not.
