I have been trying to run the grid example on an
SGI (Irix) box.

I have did the following:

1. started the name server:
> ns ~/public_html/NS_Ref
[ POA RootPOA - ready ]
[ POA RootPOA - oid: 00 0F 3F 40 06 36 0C 42 1E  - object is activated ]
[ Accepted connection from 128.0.2.110:17905 ]
[ POA RootPOA - rid: 0 oid: 00 0F 3F 40 06 36 0C 42 1E  opname: bind -
process request ]
[ Bound name: /grid.whatever ]
[ RequestReceptor: Connection timed out ]
[ Closing connection to 128.0.2.110:17905 ]
[ Accepted connection from 128.0.2.110:17909 ]
[ POA RootPOA - rid: 0 oid: 00 0F 3F 40 06 36 0C 42 1E  opname: resolve -
process request ]
[ New connection to 128.0.2.110:17904 ]
[ Closing connection to 128.0.2.110:17909 ]
----------------------------------------------------------------------------

2. Started the grid server:
> jaco demo.grid.Server
[ POA RootPOA - ready ]
[ POA RootPOA - oid: 00 11 4D 4D 4D 4D 4D 39 34 36 14 1A  - object is
activated ]

Any ideas what this problem could be. 

The problem is definately not in the nameserver... however, when I 
tried to bypass the name server and started the grid server with a file
argument so that it would write out it's ior to the file... and subsequently
started the grid client to read the server's ior from that file I got a 
message saying that the ior was an invalid one because the client
could'nt parse it. 
To check the validity of the IOR I ran the ior through dior. dior could
parse the ior without any problem:

Here are the errors that I got on the client side ( the server starts up
fine and stays up... because it is not even called.).

1. starting the server:
> jaco demo.grid.Server IOR
[ POA RootPOA - ready ]
[ POA RootPOA - oid: 00 01 37 41 0E 39 3D  - object is activated ]

2. Starting the client:
> jaco demo.grid.Client IOR
java.lang.RuntimeException: Invalid IOR format: IOR
        at jacorb.orb.ParsedIOR.parse(ParsedIOR.java:264)
        at jacorb.orb.ParsedIOR.<init>(ParsedIOR.java:50)
        at jacorb.orb.ORB.string_to_object(ORB.java:1230)
        at demo.grid.Client.main(Client.java:17)

Any ideas about this.

Thanks,
Atul
