[AG-TECH] cannot start up nodeservice

[liying]

hi,all
     i am using agtk2.3 under FC3, but it cannot start up nodeservices. 
i click the item "manage my node......", but it tells me  it cannot  
open  the  nodeservice at http://localhost:11000/nodeservice, then i try 
to set up a node with "Node Setup Wizard", but this doesn't do either, 
and the NodeSetupWizard.log reports errors as follows:
 "Traceback (most recent call last):
  File 
"/usr/lib/python2.3/site-packages/AccessGrid/hosting/SOAPpy/Server.py", 
line 63, in Run
    self._server.handle_request()
  File "/usr/lib/python2.3/SocketServer.py", line 217, in handle_request
    request, client_address = self.get_request()
  File "/usr/lib/python2.3/site-packages/SOAPpy/GSIServer.py", line 140, 
in get_request
    sock, addr = ThreadingGSITCPSocketServer.get_request(self)
  File "/usr/lib/python2.3/site-packages/pyGlobus/io.py", line 845, in 
get_request
    raise(str(self.socket) + str(" is having trouble listening!:" + 
str(ex.args)))
<pyGlobus.io.GSITCPSocket instance at 0xf5b90d2c> is having trouble 
listening!:('an I/O operation was cancelled',)"
any help would be appreciated, looking forward to your response.
