Hi,I have a qnx6.3.2 PC104 computer stack with two network cards, one is the onboard ethernet card, the other is orinoco
io-net -d ns83815 -p tcpip -p qnet &
waitfor /dev/io-net/en0
waitfor /dev/socket/2
/proc/boot/devp-pccard
waitfor /dev/pccard
io-net -d orinoco -p tcpip
gave me the error:unable to init dll devn-orinoco: No such device.
But when the machine finished booting: i typed

thx, Yuriy.
/proc/boot/devp-pccard
waitfor /dev/pccard 33
io-net -d ns83815 -d orinoco channel=11,network=**,mode=adhoc -p tcpip -p qnet bind=en0
waitfor /dev/io-net/en0
waitfor /dev/io-net/en1
waitfor /dev/socket
ifconfig en0 *.*.*.* netmask 255.255.0.0
ifconfig en1 *.*.*.* netmask 255.255.255.0
still no effects…
Hello Ericxx,
Replace
with
sloginfo –c
What is in sloginfo.txt?
Thanks,
Ericxx

Hi Yuriy, here is the output of my sloginfo, hope you could find sth out.

Hello,
fails in boot script but works correctly if entered from command line after the boot is complete?

Hi, Yuriy, My whole script is belows:

reopen /dev/con1

…
Just a wild guess, try:
sloginfo -c
/proc/boot/devp-pccard -vvvv &
waitfor /dev/pccard 59
# sloginfo > sloginfo.txt
io-net -d ns83815 -p tcpip -p qnet bind=en0

Thx, Albrecht, it works!!
Regards,
Not sure. I guess that when you pass all the modules in one go to io-net then it depends on the order in which they are loaded and initialized if it works or not. This order is not necesarily identical to the order of modules on the command line, though, especially due to the multithreaded nature of io-net.
Using the two-stage approach, the entire stack is nicely setup with the first interface, and then you only mount the second one, thus controlling the load order.
io-net is a strange program, hopefully with io-pkt we are better off …

yeah, the help doc also said the multiple io-net may cause namespace overlap, thank u.
ORiNOCO 802.11 Wireless Ethernet Controller

io-net is only responsible for navigating packets up and down the stack. I believe that the problems you have now are of a different nature:
and
make me think that the physical connection is ok but the controllers don’t like each other. Channel numbers range from 1 to 12 or something and if 3 packets have been received certainly there should be some bytes in it?
Maybe you need an wifi air sniffer to see what the controllers are doing.

thx, i used tcpdump to monitor the traffic. quite problematic:
and sometimes gave me the error: “ifconfig: getifaddrs: Address family not supported by protocol family”, somehow happened, but i have no ideas why.
tcpdump output on one machine:
but the output of another machine could not see the ip like 192.168.1.11 or 192.168.1.10 at all, but with other IPs.
and the leds of the orinoco pc card did not show that frequently as ping pkts sent out, may the orinoco card not working? but after “io-net -d orinoco channel=11,network=mywork,mode=adhoc -p tcpip” the leds start to shine, which means that the driver should be added to the card?

thx, output as follows:
Hello,
to isolate the problem I suggest to disable the ethernet wired interface
slay -f io-net
io-net -d orinoco channel=11,network=mywork,mode=adhoc -p tcpip
waitfor /dev/io-net/en0
ifconfig en0 inet 192.168.1.10 (or whatever IP address)and then startup the tcpdump utility once more
This means to me that the IP stack has died altogether.

thx, problem solved. the irq for the orinoco card on the target is not working, i changed another number. and both network cards worked well now.
