QNX 6.3 in MS Virtual PC on XP - Communication Issues  
Hi,

We have several guys here at our company that run the described senerio in the subject line and two of us have set up 
new boxes to simulate the QNX virtual machine for testing customer ATMs with a paragon simulator. We are having 
communication issues with the QNX box but no one else is, everything seems to be the same as the working machines. The 
MS virtual pc is the 2007 version. We can ping the virtual machine and than it drops and no responce after a few minutes
 we can communicate again, it does this back and forth up and down up and down. Any Ideas would be appreciated? 

Thanks,
Dirk

Do you possibly have some other completely-unrelated machine (virtual or
physical) on your network with the same IP address?  I recently saw this
problem in one of my customers' networks, and the cause turned out to be a
printer configured with the same IP address as a Cisco router that we were
using!  Took us forever to find the problem, and then we felt stupid that it
turned out to be the darn printer!


Good Luck!

Walt

That was our first thought and we got with our internal comms guy and did a trace on the network and came up with 
nothing. We had also got a static IP from him in the begining so we would not be using duplicate IPs.

Thanks Walt!

I also did some looking on the QNX site and found that my onboard NIC is not listed in the supported hardware (Intel 
82567LM-3 Gigabit Network Connection). I will see if I can get another nic from the hardware guy to see if this works 
and will report back.

Thanks,

Re: QNX 6.3 in MS Virtual PC on XP - Communication Issues  
Ok, I am at my witts end and getting frustrated with this communication issue. I have tried three different NICs and 
still having communication issues with the QNX server. The connection will stay up for about 5 min and then drop. I was 
looking at the ifconfig and saw that the interface said it was a simplex connection and would it have anything to do 
with that? I know most connections are full duplex.

Thanks for any help that comes my way!

The physical NIC that you use is not really important.  What ever model brand you use the virtual machine will always 
present the same model to the guest OS.  That is QNX never gets direct access to the hardware and always see the same 
type of NIC.

I realized this is of little help.  But more information is better then nothing.

Thanks for the info Mario, this will help me to eleminate thinking it was a hardware issue.
