Reg network

All,
I am trying to connect to a RTU(Remote Terminal Unit is an embedded device)
over the ethernet. The RTU is connected to our local network through a hub.

The RTU network details are:
IP Address is 192.168.1.8
Default Gateway 192.168.1.1
Subnet mask 255.255.255.0

I have a windows2000 machine IP address 192.168.1.42 with the same Default
Gateway and Subnet mask. The windows machine can ping and telnet to the RTU.

But I have a QNX4.0 system with IP address 192.168.1.7with the same Default
Gateway and the subnet masks. The windows 2000 machine and QNX4.0 machine
are also connected through the hub. From these QNX4.0 system I am not able
to ping or connect to the RTU. But I can ping the windows 2000 machine
through the QNX4.0 system. I can ping or connect to any machine on our local
network through the QNX4.0 machine except the RTU.

Do I need to configure anything in the QNX4.0 machines to connect to the
RTU?? Any ideas??

Any help is greatly appreciated.

Best Regards,
Raj

This is only a guess. Ofetn times I find that when you are certain
that routing is set up correctly but still appers not to work, it is
because te routing in the other direction may not be set up correctly.
I.E. teh ping IS getting there, but the responce is NOT getting back.

Look at the routing table on both hosts.
netstat -rn

You can’t possibly be running QNX 4.0 as it didn’t have ethernet drivers or
a tcp/ip stack.
