[omniORB] Problem with Naming Service between two networks

[Brecht Vermeulen]

Hi,

I've got a problem with the omniORB Naming Server running on a machine
orpheus.atlantis.rug.ac.be (157.193.184.9) and a client running on
helios.test (10.10.10.100).

Running nameclt list on helios.test gives the following :
list: Cannot contact the Naming Service because of COMM_FAILURE.

Both hosts have the following /etc/omniORB.cfg 
ORBInitialHost orpheus.atlantis.rug.ac.be
ORBInitialPort 8088 

Filling in the IP address for orpheus doesn't work neither.

Within the atlantis.rug.ac.be domain I have no trouble with using the
Naming Service.

If I put in the /etc/hosts of helios.test the following, it works :
157.193.184.9   orpheus.atlantis.rug.ac.be   orpheus
(the plain orpheus is the clue !)

I can run the IOR example perfectly between both hosts.

The platform is Linux Debian 2.2, omniORB 3.0.1.

Has anyone some ideas or is it a bug ?

best regards and thanks for your time
