I just installed Momentics Lite 6.3.2 under VPC 2007. Everything appeared to
go well except for the networking.

Does anyone know what hoops to jump through to get standard TCP/IP
networking working with the tulip driver in VPC? When manually configured I
get duplicate packets and network errors. DHCP configuration fails
completely.

If I can't get this working in the next couple days, I'll probably give up
on it and try a stripped down Linux environment instead.

Thanks in advance,
OC1

Re: QNX native networking under VPC

Am I the only person trying to use Momentics in a VPC environment? Nobody else has experienced any networking problems?

I have used (successfully) 6.3.2 on vpc.

What kind of networking problems are you experiencing?

Duplicate packets and errors when network is manually configured. DHCP fails to work at all.

See first post in this thread.

Thanks for the response. At least someone has it working.

Could it have anything to do with the Core 2 duo CPU?

I run it on core2. I don't know if it has anything to do with it, but I doubt.

The duplicate packets: could you check your MAC in the VPC, and make sure you don't have another NIC on your network 
with the same MAC?

There is a way to configure MAC in Neutrino in software. When you boot in Neutrino, use it to determine what is Neutrino
 reporting as MAC address (might be different from "hardware" VPC provided one).

Thanks for the tips. I checked the MACs and this one is unique (although the exercise was not wasted. I found couple 
other VMs with the same MAC. Neither of them was active at the time I tried to configure this VM).

I have checked the MAC using ifconfig and compared with the one from VPC and they agree.

Is there some way to set verbose diagnostics on the driver to see what it's trying to do?

Thanks,

Re: QNX native networking under VPC

Hello,
In order to set verbosity use “verbose=num” option, for example
io-net -d tulip [option[,option ...]] verbose=1 &

The output goes to slogger, invoke sloginfo to view.
Please see description of devn-tulip.so in Utilities Reference.
