I was only trying to run the cross wired cable from the QNX NIC to the windows
PC at this time. I do not have any information at this time about how the
server’s network is configured at this time.

I have experienced the following network problem under QNX4. Any
solutions are greatly appreciated.
I attempted to connect to an AIX based server from a panel pc with
touchscreen using QNX 4. I could not successfully ping the server.
Parameters are as follows:
Server IP: 22.214.171.124
Gateway IP: 126.96.36.199
QNX IP: 188.8.131.52
What netmask does QNX use? Post the output of ‘ifconfig en1’. Does
this netmask agree with the netmask that windows uses? QNX TCP/IP
will not accept a netmask that creates a supernet, and will re-write
it. Does this netmask agree with the server?
The results of ifconfig en1 are as follows:
inet 184.108.40.206 netmask ffff0000 broadcast 220.127.116.11
This matches the mask of windows (255.255.0.0).
What is the output of ‘netstat -rn’?
I do not know, but I do have the output of netinfo -l and netstat -in, they are as

Which network card are you using?
Have you tried forcing half or full duplex when you start Net.?
No, is this an option when starting Net.rtl? What are the benefits of forcing each
Did the QNX driver get the media rate correct? This is available with
netstat -L or netinfo -L (can’t remember which).
I believe that the media rate is correct (10mbps). I will confirm it.
(see netinfo -l above).
When you say that you cannot ping, what is the error that ping
returns? Does it say “host unreachable”, “no route to host”, “network
unreachable” or anything like that?
No, it does not give any specific message (I forgot to try with the verbose
option). This machine is now at the customer site. It only stops after trying to
send the first packet (I must use control-C to escape from it).
The results of netstat -in is as follows:

I am able to ping the local host (127.0.0.1) successfully.
