[ewg] iWARP WAN test problem

[Woodruff, Robert J]

The InfiniBand subnet manager is not needed for iWarp, so this is not related to
your problem of doing an RDMA over the WAN.

And the subnet manager fails to start.

[root at tera litan]# /etc/init.d/opensmd start
Starting IB Subnet Manager......                           [FAILED]

Dear all,

I am trying to test RDMA operations over WAN(from Michigan to NY) on iWARP card. After install OFED-1.5.2 on both sides, I ran "rping", and it reported following problem::

Server side :
[root at tera ~]# rping -s

Client side:
[root at netqos tan]# rping -c -v -a 192.84.86.XX
cma event RDMA_CM_EVENT_ADDR_ERROR, error -2
waiting for addr/route resolution state 1
Following is the server info:

Server side:
ip: 192.84.86.XX
iWARP card:Ethernet controller: NetEffect NE020 10Gb Accelerated Ethernet Adapter (iWARP RNIC) (rev 05)
kernel: 2.6.18-194.3.1.el5 with Scientific Linux 5.5

Client side:
ip: 198.124.220.XX
iWARP card: Ethernet controller: NetEffect NE020 10Gb Accelerated Ethernet Adapter (iWARP RNIC) (rev 05)
kernel 2.6.18-164.11.1.el5_lustre.1.8.3 with RHEL 5

All socket based communication can be done successfully. And all RDMA operations can be done successfully locally. But all RDMA operations are failed between two remote sides. All help will be really appreciated.
