<div>Hi Everyone,</div>
<div> </div>
<div> Thank you so much for your replies. Still the same problem.. able to ping sucessfully from one side but not from the other.</div>
<div> </div>
<div>Hi Tzachi and Leonid,</div>
<div>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.</div>
<div> </div>
<div>b. I disabled and enabled network interfaces on both ports, but no luck. It still doesnt work.</div>
<div> </div>
<div>c. I know that its <strong>not</strong> 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. </div>
<div> </div>
<div>d. I then installed Ultra VNC and ran one end as server and the other as client.. <strong>And it worked perfectly fine!!!!!!!</strong>.. 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. </div>
<div> </div>
<div>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. </div>
<div> </div>
<div>f. ipconfig and vstat return the correct values.. here's the output of these commands on computer 1</div>

<div></div>Hi Fab,<br><br> 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?<br>
<br>p.s. There is a typo in my previous mail. I had opensm running on computer 2 and not computer 1.<br><br>regards,<br>Ashwath<br><br>
