Usage for Corba controlled execution of Vic
*******************************************

The file Viciface.idl holds the IDL interface. The interface has methods
start and stop. Their implementations are in viciface_impl.cpp. Start
method  fork()s and exec()s Vic. Stop method send a SIGINT signal to Vic
which is  handled by Vic's internal signal handler. Vic quits after
catching the signal.

Client.cpp and server.cpp hold the implementations for the client and
the server respectively. Naming service is used so you must have nsserv
running and pass the naming reference in command line arguments. You must
have the executables viccl and vicsv in the same directory as the Corba
executables because exec() calls them from ./ .

Compilation:

If the .idl file hasn't been compiled:
[iines sov]$ idl viciface.idl

Otherwise just:
[iines sov]$ make

Running:
(Notice that vicsv and client must be running in different machines. The
reason for this is Vic and the problem is under further study.)

1. Vic server
[hessu sov]$ ./server -ORBnaming `cat /PATH/Naming.ior`	// Corba server

2. server
[iines sov]$ ./vicsv 				// Vic server

3. client
[iines sov]$ ./client -ORBnaming `cat /PATH/Naming.ior` 
		HESSU_ATM_ADDRESS_HERE	        // exec()s Vic client

Explanation:
The Corba server running in hessu exec()s the Vic client in hessu. Vic 
server is running already in iines. Client can be running basically 
anywhere in the network. After the client sends start to the server viccl
is started and tries to connect to the address supplied in the command
line.

(Note that Linux ATM signalling is used here and the network side must
started on the machine that vicsv is started.)
(Note something seems to be changed since vic was first modified to run on
ATM). With the CORBA implementation the following start order of programs 
is necessary:
- vicsv runs in iines (atmsigd -N on iines)
- corba server runs in hessu (i.e. client starts in hessu)
- corba client runs in anywhere in the net with the destination address
  parameter set to iines' ATM address
