Multiple networks HOW?

I have just installed QNX to use in my research project. For the project
I would like to have at least three separate TCP/IP networks that the
same program is simultaneously connected to.

How do I do it in the QNX. I have do it earlier in ChorusOS and Linux.
I have three network cards in the machine. The Linux on
the same machine finds them all, but the QNX only reports en0 and en1 in
the network Cfg program in Proton MicroGUI. Two of the cards are 3c905C
and one is 3c905B. The B-card is my primary internet connection and it
works. Is it possible to add the third card to the system? What should I do?

I have just installed the QNX and it seems to be working just fine.
What does the message ‘Unable to determine active media’ mean? It is
usually the last message in the boot text. It appears once or twice.
I have not noticed any problems in the system behavior.

Arrrg, is the QNX4 or Neutrino?

I have just installed QNX to use in my research project. For the project
I would like to have at least three separate TCP/IP networks that the
same program is simultaneously connected to.

For QNX4, start by adding a “-d 3” parameter to Net. The default
is 2. Next, start each driver with a different -l parameter.
Make sure that there is enough delay between starting the drivers
and Socket. Otherwise Socket will come up and not see all of
the drivers. Finally, configure the network using ifconfig.
Your interfaces will be en1, en2, and en3, associated with the
-l parameters.
