Network available but no network connectivity

Network available but no network connectivity

[Satz Klauer]

Hi,

currently I fail with a problem that I already had (and never could
solve) with QNX 6.4.1, now I tried again with QNX 6.5 but still don't
get it working. I start qemu with

qemu-system-x86_64 -hda qnx.img -m 512 -net nic -net user

(brain-attritional simple and well-working with all other operating
systems). QNX comes up without problems and it detects the network
card successfully.

But with that network interface nearly nothing is possible: DHCP does
not work, assigning a fixed IP 10.0.2.15 / netmask 255.255.255.0 works
but I can't reach anything outside of this qemu-envorinment. The
default gateway is set to 10.0.2.2.

Within the QNX-forum nobody could help, so may be here somebody has
some hints what I could try?

Thanks!

Try different models: -net nic,model=e1000, -net nic,model=rtl8139, net 
nic,model=eepro100

Yes, I have QNX (although I only tried QNX 6.3.2) as guest with working network.

As I posted on [1], I needed "-net nic,model=ne2k_pci" and to follow the
instructions in [2], the part that says: "If this is not done, networking will
not work, so we have to manually start it every time. To do this, type".
Although I've only done this the first time and when I re-start the guest it
just works.

I don't know if this would work on QNX 6.5, but I suspect it does.




Thanks a lot,
Rodrigo
