[omniORB] DHCP problem??

[Eva Pérez]

Hi!

I hope that someone could help me with this. Thanks in advance.

I have implemented a client-server application using omniORB 3.04 
(Server is implemented using C++ and client uses Java). The client and 
server processes run on different machines connected through a LAN and 
I'm using the omniORB nameserver on the C++ server machine.

All worked fine (so, the java client connected to the c++ server and 
they exchange data) until I moved the java client to another machine (to 
a laptop with the same operating system Linux 7.3 an connected to the 
same LAN) but with the difference that it uses DHCP for IP assignation.

I understand that this would not be a problem, because it could be 
possible to communicate two processes using omniORB and the DHCP 
protocol, isn't it?
That I don't know is if there's to consider something special with this 
configuration...

The communication between the two processes is not pure client-server 
communication, I mean first the client connects to the server (this 
works, the server machine has a fixed IP…) but the client sends the IOR 
reference because later it will act as server for receiving data and the 
fail appears when the server uses the received IOR reference for sending 
data to the client ("IDL:omg.org/CORBA/COM_FAILURE:1.0"…)

I don´t know if the problem is that the string IOR reference is 
generated wrong or that the server doesn’t find the client due to the 
DHCP … (with static IP in the two machines all works fine)

Perhaps someone has found this problem before and could help me (I hope) :-)

Thanks in any case to all the people that reads this trying to help me.

Eva.
