In the project of My lab, we use TAO , the implementation of Corba, to compose the distributed software for LAMOST telescope.

I get one problem, when the default gateway of network setting of my computer is wrong, it always takes a long time, about 10 seconds to get through belowing codes.

  CosNaming::NamingContext_var root=CosNaming::NamingContext::_narrow(NamingObj.in());

also this clause takes about 10 seconds to pass.

  PortableServer::POA_var poa=PortableServer::POA::_narrow(RootObj.in());

 

  It also happens when I unplug network cable, that I work on Linux, the system can not automatically find unconnect to network .

  I spent whole morning trying to fix the problem, but in vain. I have tested to specify the Naming Service using -ORBInitRef *** or  -ORBNameServicePort ***. They are not usefull.

  I give up. Future, when using the controll software in LAMOST telescope, remember to fix the default gateway setting, or leave it blank on Linux. Otherwise, it won't work well.
