Yes, MIB600 is pingable. The correct way of connecting with
SerialForwarder is:
1. Start SF and enter the IP and port of your MIB600 to the appropriate
boxes
2. export [EMAIL PROTECTED]:9001
3. Run your java app
I suspect you've started SF with the MIB600 IP and the java connection
is refused because SF has already occupied the device (if you've done
step 1 mentioned above).
As Michael said, you don't need SF if there's only one listener app, in
that case your approach should work.

Harri

Subject: Re: [Tinyos-help] Fwd: MoteIF error with XBow MIB600
Just tossing in a few cents that probably won't make any sense...but...
The addr: 192.168.2.8:10002 is that of the MIB600? If so this is what SF
will want to attach to. I dunno if the MIB is pingable, but you might
see if it responds at that addr.
It's not clear if it's your app or SF that is returning your error...
If it's the app, you probably need to change the MOTECOM to one
appropriate for the SF, not the MIB. Although I would think that you
could dispense with SF and go directly to the MIB...
If you can run netstat on the .2.8 host you can see what state that port
is in, it might not be accepting for some reason. Often a reboot is in
order to clear the TCP state machine. The same goes for the SF port on
whatever host it is running.
Also there could be permission problems...say your app is actually an
applet...It's too bad, but Connection Refused is kinda a catchall, maybe
you can debug in and see where it is really throwing.
