I tend to construct an ad hoc among several laptops with QNX 621 and Windows Xp.

I learned that it could work properly among QNX 621 machines(the same platform), but not among QNX 621 and WinXP. And 
there is a new version of the orinoco driver for QNX 6.2.1B that can make the orinoco card to work properly under QNX 
621 and WinXP. Where can i download it? 

Thx,
Alex

Re: Orinoco PC card under Adhoc mode

I got the evaluation ver of QNX 6.3.2. And i can establish the p2p adhoc between QNX 6.3.2 and Winxp. But still one 
problem: Winxp can ping thru QNX, but QNX cannot ping Winxp. What's wrong with this?

And another is with "nicinfo", i had the following output on QNX 6.3.2:
 Network Name(SSID)------------------
 Channel:-----------------------------------4294967295
 BSS Type --------------------------------Unknown

All of which i had configured via 
"io-net -d orinoco channel=11,network=**,mode=adhoc -p tcpip"

Thx,
Alex

RE: Orinoco PC card under Adhoc mode

Very strange.  The fact that XP can ping QNX suggests that it should be
working.  Do the packet counts on QNX increase appropriately as you do the
pings?

What are the MAC addresses for XP and QNX?  Has arp worked (if you do arp -a
for XP and QNX, do they give the correct IP / MAC mappings?)

Re: RE: Orinoco PC card under Adhoc mode

I checked the arp table on both Winxp laptop and QNX632 laptop.
They are both correct in the ip and mac mapping.

And for ur first question, Winxp--->QNX, ping successfully, i checked the pkts stats on the QNX via nicinfo, it should 
work properly. Whenever i pinged from Winxp with 4 pkts, the stats on QNX increased correspondingly. With ocassonal 1 
more pkt in the Tx or Rx. (Where does this pkt come from?)

But QNX-->Winxp still not thru, and "TXed OK" pkts increased. 
Another thing is that the channel id didnot change whatever in AP mode or adhoc mode. And BSS type is still Unkown. So 
any possible reasons? Thank u.

Re: RE: Orinoco PC card under Adhoc mode

New update.
The ping operation from QNX to Winxp is okay from the very beginning. 
The QNX terminal didnot show the reply pkt until 1min later. Why such a LONG DELAY in this case? Moreover, 0% pkt loss 
shown on QNX laptop.

But the output of "nicinfo" still the same problem.

RE: RE: Orinoco PC card under Adhoc mode

Hmmm... On the plus side, at least we know that the WiFi link appears to be
doing something appropriate.

Possibilities:  
1) QNX taking a long time to transmit,
2) XP is taking a long time to reply
3) QNX receives the packet but the ping utility doesn't respond quickly.

Is it possible to put WireShark on the XP side and see when the ping packets
are rx'ed / tx'ed?

Is there anything else running on the QNX side which would result in the
ping utility not being given any CPU to run for a long period of time?

R.

Re: RE: RE: Orinoco PC card under Adhoc mode

Thx, Robert.

I installed Wireshark on my Winxp laptop. Great pkt sniffer!
Then i tried to ping from QNX to Winxp, the annex is a snapshot.
It seems that QNX is querying DNS Server for 4 times, this process cost quite a lot of time and increased by 2 times 
each time. Then from the time when the ICMP ping req pkt from QNX, everything worked fine.

Btw, how about io-pkt stack? Maybe i can try this to solve the strange "BSS Type, Channel ID" problem.

RE: RE: RE: Orinoco PC card under Adhoc mode

Ah yes.... I'd forgotten about the DNS lookup / time out.  "ping -n" will
use only numeric output and not do the DNS stuff.

Unfortunately, we don't have a driver for the Orinoco card under io-pkt, so
that's not going to help.  Hopefully someone else might be able to comment
on the nicinfo issue on Monday.  Given that everything else is working, this
is likely just a display bug though.

	Robert.

Re: RE: RE: RE: Orinoco PC card under Adhoc mode

Hi, Robert

Another problem just discovered. The Orinoco PC card on QNX turned down automatically after several hours of working. 
And it can recover only by itself, like pinging another machine.(If i ping from Winxp, the PC card on QNX still couldnot
 wake up.)
So does it have the sleep mode in QNX or how can i set the mode to make it work all the time?

Thx,
Alex

RE: RE: RE: RE: Orinoco PC card under Adhoc mode

Hi Alex:

That one's getting into details of the driver that I'm not familiar with (it
being an io-net driver).  Hopefully Hugh will respond...
