Hi everyone,

I'm using the serial forwarder in c available
here<http://code.google.com/p/tinyos-main/source/browse/trunk/support/sdk/c/sf/>.
After I set up the serial forwarder (use the example sf.c), I succeeded in
both reading from it (sflisten.c) and writing to it (sfsend.c), from the
local machine. However, when I try to access it from another machine, the
following error keeps prompting when function connect() is called to
establish a connection to the serial forwarder: *Connection timed out*. Can
anyone give some suggestion on what might be going wrong, perhaps privilege
issues? Thanks very much in advance.

BTW, I'm using Ubuntu and TelosB motes, serial forwarder uses port 9001.
Two machines can ssh to each other.
