Hi Michael, Thanks for the reply. I have installed both my motes using RJ 45(or say using IP address) cable only. I cannot use the Serial cable connection to my motes as it can be just connected using RJ 45 cable. I am confused about the below lines which is there on http://docs.tinyos.net/tinywiki/index.php/Mote-PC_serial_communication_and_SerialForwarder#BaseStation_and_net.tinyos.tools.Listen . which says that, "BaseStation is receiving your BlinkToRadio packets and sending them to the serial port, so if it is plugged into a PC we can view these packets. The Java tool Listen is a basic packet sniffer: it prints out the binary contents of any packet it hears."
So, my question is that, "is it necessary for me to have my mote connected to PC (via serial com port) ? or Is there any mechanism via which I can sniff this packets as I am using RJ 45 cable to connect to my motes? I don't have serial port connection to my motes. " Waiting for your kind reply.

And further that you are seeing leds blink as one would hope... Then, the error you are getting indicates that Listen is expecting to connect to a network port, usually the SerialForwarder. This is the default behavior, but I always recommend just forgetting about SF and going direct, as it were. To connect Listen to the actual input port you need to set use something like "-comm serial@COM1:mica2" where COM1 is the I/O port your mica2 is plugged into. You can also set the same string in a MOTECOM environment variable and not have to bother with it on the command line. Probably searching for MOTECOM will turn up some better advice.
