Hi all,
this is what my linux exports looks like and it works for me
<root> [36] (~) # cat /etc/exports
# See exports(5) for a description.
# This file contains a list of all directories exported to other
computers.
# It is used by rpc.nfsd and rpc.mountd.
/ (rw,insecure,all_quash)
<root> [37] (~) # 

ofcourse it can be a security hole but its good for temp file transfers
hope it helps
