Network issue

Hopefully this is an easy one for you guys. I’m
trying to view web pages on QNXDevice. I can’t
ping it either.

In the discussion below, MyComputer is Windows 98
while QNXServer and QNXDevice are QNX systems.
QNXDevice boots from it’s own drive.

I can ping MyComputer <–> QNXServer just fine.
I can ping QNXServer <–> QNXDevice just fine.
However, pinging from MyComputer → QNXDevice
does not work.

Lets say that MyComputer’s IP address is x.y.11.80
QNXServer’s address is x.y.254.1
QNXDevice’s address is x.y.254.5 (looks like node 5
to QNXServer, but node 1 to itself).

Any ideas on what to look at?

Thanks,
Barry

The “ifconfig” only allow you to define a netmask of “255.255.255.x”, which
means that QNXServer x.x.254.1 can see QNXDevices x.x.254.5, and vice
versa, fine. Windows 98 can see the QNXServer probably because you have
setup a “route” to include the x.x.11.80 IP address, but not so in the
QNXDevices.
So the QNXDevices can only see x.x.254.x systems. This may be the problem.
Check /etc/resolv.conf or see if you are executing a “route” command
somewhere
on the QNXServer. Hope this helps.

Check the netmask, I bet your “MyComputer” and your “QNXDevice”
is not on same subnet.

On QNXDevice, do a “route add x.y.11.80 x.y.254.1” might
fix your problem.

Thanks guys. The netmask was set to 255.255.254.0. That was
the problem.
