[maemo-developers] [maemo-developers] osso_socket doesn't work under scratchbox

[From: Vladislav Vasiliev]

I already posted message about this issue some time ago:
http://maemo.org/pipermail/maemo-developers/2006-July/004752.html
Unfortunately I didn't get any answers on that post.
This time I'm trying to provide more details:

My environment: Maemo 2.0 i386 rootstrap, af-sb-init.sh started.
I'm using /usr/share/doc/osso-ic-dev/examples/osso-socket.c example.
Compile it:
gcc osso-socket.c -o osso-socket `pkg-config --cflags --libs osso-ic
glib-2.0`   -DDBUS_API_SUBJECT_TO_CHANGE
and run:
run-standalone.sh ./osso-socket 192.168.1.1 80
So, this is the output I get:
socket error: No route to host
Tracking osso_socket(2=PF_INET, 1=SOCK_STREAM, 6=tcp) = 3

And it fails. Here is the strace output:

But it works without any problem on the device.

Does anybody experience similar issues?

I'm just wondering if it's possible at all to run/debug connectivity
applications under scratchbox.
If it isn't it should be mentioned somewhere in the maemo documentation,
I believe.
