[ECOS] network tests not working on ipaq

[Weilong Li <weilongli2000 at yahoo dot com>]

I'm using the latest cvs version of ecos and network
package, and I successfully built the network tests
for ipaq.

However, when I run them on ipaq, I got something
wrong.

I tested tcp_echo, and the ip address of ipaq (the
target) is 192.168.1.20, which is assigned
by bootp from redhat linux host.

Set background load = 50% starting 10 threads

Final load[1176] = 361276 => 50%

At this moment, it stays there, and on linux host,
I typed tcp_sink,
#>./tcp_sink 192.168.1.20
Start TCP test - SINK mode to 192.168.1.20
Can't connect to target: No route to host

and at this time I cannot even ping 192.168.1.20.
(my linux host machine has ip address of 192.168.1.9).

I found out that after redboot boots from ipaq,
I can ping ipaq from the linux host, however,
if I remotely run ANY tests program, the redboot
will be stuck, so ipaq is not responsive to
any connection to it, so I cannot ping ipaq from
linux host.

So what is the problem?

thanks,

Weilong
