Hi,
It seems that your problem comes from some kind of
firewall/filter/antivirus that is installed on one machine but not the
others.
In order for us to get more information, please do the followings:
1) Delete the arp tables on both machines (run "arp -d"), than start
wireshark on both and ping from machine a to b.
2) Delete the arp tables on both machines (run "arp -d"), than start
wireshark on both and ping from machine b to a.
Please send me the captures of these two experiments. (you should have 4
files).
Can you try using a 3rd computer and see how it works?
Thanks
Tzachi

Subject: Re: [ofw] Setting up Infiniband over WinXp- Help Needed
Hi Everyone,
Thank you so much for your replies. Still the same problem..
able to ping sucessfully from one side but not from the other.
Hi Tzachi and Leonid,
a. I followed your steps. I am able to view the infiniband data
when I run the server (ib_send_bw -a) on computer 2 and I connect to
this from computer 1 (ib_send_bw -a <ip>). However, I do not view this
data when I run server on computer 1 and connect from computer 2. I get
a pp_connect_sock<ip,port> failed in the latter case.
b. I disabled and enabled network interfaces on both ports, but
no luck. It still doesnt work.
c. I know that its not a hardware issue because the same problem
persists when I interchange the infiniband cards i.e. the card that was
actually plugged into computer 2 is now plugged into computer 1 and vice
versa. I get the same issue in this case too.
d. I then installed Ultra VNC and ran one end as server and the
other as client.. And it worked perfectly fine!!!!!!!.. Both from
computer 1 to computer 2 and computer 2 to computer 1. I then installed
WIRESHARK on both computers. I could see the Computer 2 send the Ping
requests to computer 1 in Computer 2's Wireshark window but for some
bizzare reason computer 1 was rejecting these ping requests. When I
checked the connection status of Computer 1, I could see the number of
received packets also increasing but Computer 1 did not send back any
packets.
e. I suspect this issue is arising because of some win xp
setting in Computer 1. There is no difference between the two PC's. both
are brand new PC's having Xp. The only difference is that I have a wifi
driver on computer 1. all my firewall settings are disabled. I even
uninstalled my wifi driver, but still the same problem persists.
f. ipconfig and vstat return the correct values.. here's the
output of these commands on computer 1

Hi Ashwath,
If you still have problems, send us, please, the output
of 'vstat -v' and 'ipconfig /all' on both machines.
TIA

Subject: RE: [ofw] Setting up Infiniband over
WinXp- Help Needed
Hi Ashwath,
There are a few things that I would like you to
try:
1) Please run some low level IB test to see that
traffic is indeed ok. On one computer please run
ib_send_bw -a
and on the other computer please run
ib_send_bw -a 192.168.0.x (where x is the
ip of the remote side. Please start this test with the Ethernet
addresses of the ports).
2) Assuming all works well please try to disable
and enable the network interfaces (ipoib) on both ports. Please see if
this helps.
3) If this doesn't help, you will probably need
to change the parameter of "Guid bitwise mask" to e7. To do this, please
open the device manager, than go to "network adapters" select the ipoib
interfaces and than right click properties. Select the "Guid bitwise
mask" and change it to e7.
If all doesn't help, can you give me remote
access to these stations?
Thanks
Tzachi

Hi Fab,
I restarted opensm on the
other node. I ran both opensm and ibdiagnet on the other node (not on
the node where opensm is running). The logs are similar to the one I
attached in my previous mail. (Computer 1 :-192.168.0.1 logs in my
previous mail). I have disabled firewall settings on both nodes.
However, I still cannot get it to work. I cannot access the shared
folder of each node from the other. Is there something else I can try?
p.s. There is a typo in my previous
mail. I had opensm running on computer 2 and not computer 1.
regards,
Ashwath

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.
