Hi, 
 
 
 
  I'm using X-Bone-3.2 on Linux version 2.6.18-8.el5.
 
  I can successfully contruct Star overlay with 4 nodes and Linear overlay with 3 nodes in local area. When I try to construct an Ring overlay and Linear overlay with 4 nodes, I receive the following error: 
 
 
 
 -> XB_VN_Graph::compute_routes HASH(0x940f7c0)
 
<- XB_VN_Graph::compute_routes
 
Use of uninitialized value in string ne at
 
       /usr/local/xbone/programs/modules/XB_VN_funcs.pm line 375 (#1)
 
   (W uninitialized) An undefined value was used as if it were already
 
   defined.  It was interpreted as a "" or a 0, but maybe it was a mistake.
 
   To suppress this warning assign a defined value to your variables.
 
 
 
   To help you figure out what was undefined, perl tells you what operation
 
   you used the undefined value in.  Note, however, that perl optimizes your
 
   program and the operation displayed in the warning may not necessarily
 
   appear literally in your program.  For example, "that $foo" is
 
   usually optimized into "that " . $foo, and the warning will refer to
 
   the concatenation (.) operator, even though there is no . in your
 
   program.
 
 
 
Use of uninitialized value in concatenation (.) or string at
 
       /usr/local/xbone/programs/modules/XB_VN_funcs.pm line 376 (#1)
 
<- XB_VN_funcs::make_node_config
 
  ! make_node_config caught unknown exception: Can't use an undefined value as an ARRAY reference at /usr/local/xbone/programs/modules/XB_VN_funcs.pm
 
line 
 
 
 
  Is this caused by configuration error?
 
  Any help will be appreciated.
