I have 2 3COM 905B PCI network cards running on a HP VL600 computer running
QNX 4.24 AND qnx4.24 tcp/ip.
Everytime we start the node up we get the following error
from ifconfig :
" no such interface"
We have two ifconfig lines and they are:
ifconfig en1 PcvHost$NODE up
ifconfig en2 a-historian1 up
It is on the second ifconfig line that we get the message:
We used nettrap to get the appropriate irq’s, io port addresses and logical
network numbers for the startup lines of the network driver ( Net.ether905).
We have included one line in the sysinit file upon startup
and the other in a script file that gets executed within the sysinit.
The result is that we have no communication with the second network card.
What does the error message above indicate ?
Is this a timing issue when starting up the drivers ???
- Any help would be greatly appreciated.

Perhaps this is your problem: AFAIK nettrap doesn’t deal much with the
logical
network numbers, so they might be wrong. Try to start the Net… drivers
manually
and give them distinct logical network numbers, such as
Net &
Net.ether1000 -l1 -i… -p… &
Net.ether1000 -l2 -i… -p… &
and then add a little ‘sleep 3’ to give them time to settle up before
starting
the TCP/IP stuff.
You can check the existance of the interfaces with the ‘netstat’
utility:
netstat -i
will give you a list of all available interfaces.
BTW: you also should assign the IP addresses in your ‘ifconfig’ lines
…
