+Our current recommendation is to use Inferno (http://www.vitanuova.com/inferno)

+following command:
+   ; styxlisten -A tcp!*!564 export '#U*'
+
+The -A specifies an unauthenticated export.  The 564 is the port # (you may
+have to choose a higher port number if running as a normal user).  The '#U*'
+specifies exporting the root of the Linux name space.  You may specify a
+subset of the namespace by extending the path: '#U*'/tmp would just export
+/tmp.  For more information, see the Inferno manual pages covering styxlisten
