[omniORB] Re: omniorbpy narrow problem (NameService Problem?)

[Manuel Iglesias]

I found a difference comparing the traces of my ubuntu box vs. the debian
box.

On my ubuntu box (where it works as expected) I have

omniORB: AsyncInvoker: thread id = 3 has started. Total threads = 2
omniORB: Scavenger task execute.
omniORB: Client attempt to connect to giop:tcp:localhost:2809
omniORB: Client opened connection to giop:tcp:127.0.0.1:2809

but in the debian box

omniORB: Client attempt to connect to giop:tcp:127.0.0.1:2809
omniORB: Switch rope to use address giop:tcp:127.0.0.1:2809
omniORB: AsyncInvoker: thread id = 3 has started. Total threads = 2
omniORB: Scavenger task execute.
Traceback (most recent call last):
  File "adder.py", line 24, in <module>
    nameRoot = nameRoot._narrow(CosNaming.NamingContext)
  File "/usr/lib/python2.5/site-packages/omniORB/CORBA.py", line 787, in
_narrow
    return _omnipy.narrow(self, repoId, 1)

I don't know what the Switch rope means.
It seems that for a good reason it can't establish a connection.

Did you try to change your nameservice uri from
localhost to 127.0.0.1?

*I suspect that it handles the localhost as 127.0.0.1 looking at the above
trace, but haven't try to change that as you suggest, could you point me how
to accomplish that? Thank you.

I will really appreciate if someone have a clue about this problem.
