[omniORB] [help] [beginner] cannot run naming service examples from python chapter 2 "The Basics"

Fri Aug 19 12:18:14 BST 2011

Hello,

I'm testing omniORB 4.1.2 on Ubuntu Lucid. I'm just trying to run the
python examples from this page:

  http://omniorb.sourceforge.net/omnipy2/omniORBpy/omniORBpy002.html

2.4 and 2.5.1/2.5.2 both work. However, 2.6.3/2.6.4 don't work. I've
put the server code into a script (server2.py) and the client code
into client2.py. When I run the server code with this command:

  python server2.py -ORBtraceLevel 40

... it fails. The output is pasted below. Obviously this line doesn't look good:

omniORB: Unable to open new connection: giop:tcp:localhost:2809

... but I don't know why it is unable to open a connection. I have
this in /etc/omniORB4.cfg:

  InitRef = NameService=corbaloc::localhost/NameService

Again, I cannot tell if that is causing the problem or not.

omniNames is running, and here are the contents of its log:

/var/log$ cat omniorb4-nameserver.log
