tcpip problems

Hello,
Hoping for some help with the following:
I have a start-up script with the as follows:
io-net -dspeedo -ptcpip
ifconfig en0 192.168.0.11
route add default 192.168.0.1
I can ‘Ping’ myself (192.168.0.11) but I can’t ping anything else.
192.168.0.1 is a netgear router. I have another PC is 192.168.0.2 neither
one can be reached. I get the error message “host is Down”
Any ideas/suggestions
Thanks
Viraj

Are netmasks the same? What nicinfo output says?

At the risk of being called a paranoid, i ask you…Can you ping 192.168.0.1
(Netgear Router) from 192.168.0.2 (Another PC) ? If yes…Swap the network
cables of 192.168.0.2 and your Qnx box.As far as i feel, there is no issue
with routing or netstat.One more thing you could is to delete the arp
entry( arp -d 192.168.0.1) and try again.

Hope it helps,

One more thing i noticed that your netmask is 255.255 not 255.255.255.0 as
you mentioned.I could infer it from the netstat output

192.168 192.168.0.11 U 1 11 - en0
Could you also post the ifconfig -a output?

IRQ 2 is not possible for a standard board ! IRQ 2 is usually
redirected to IRQ 9 ! Check your settings (may need to check BIOS irq
settings)

The BIOS has PCI INT C (Ehternet) set to IRQ 11
I changed it to IRQ9 (no difference) There was no IRQ2 available
the ifconfig -a has the following:
lo0: flags=8009<UP,LOOPBACK,MULTICAST> mtu 32976
inet 127.0.0.1 netmask 0xff000000
en0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST>mtu 1500

When performing the function, pci, it lists the intel 82559er chip as
being assigned to pci int A. The bios has the ethernet pci int C. is there
a way to change the speedo driver to look on int C?

This board has communicated from a DOS operating system, so I know the
hardware works fine.

This is a single function device, so it can only work on INT A. What
you have to worry about is which interrupt line it is connected to.
The interrupt PIN is fixed and cannot be moved, but the interrupt
LINE can be changed. If you post the output from ‘pci -v’ it would
be more helpful.

Is this some type of embedded system? I see that the ethernet chip
is connect to IRQ2 which is normally a cascade interrupt from IRQ8.
