Hi Christopher,

Thanks for your reply. I am aware of that one machine can have many
IP-addresses, hence I would be happy if I could get to the list of
IP-addresses, or alternatively the MAC-addresses. Or a third alternative
would be to get the networkname of the computer.

The problem I'm trying to solve is related to a framwork I've created for
remote startup of processes/applications. I have one server PC, which
controlles a number of client PCs. The clients registeres at the server as
soon as the client PC is up running. Depending on the client, the server
assigns a set of processes/applications that the client should be able to
start locally on the client (like Word, Excel, Notpad, or any other SW). All
of this is currently working just fine (using RMI), but in order to make the
client SW as general as possible (I don't want to supply startup arguments
that are special for each client), I was thinking of making it possible for
the client SW to be identical on all clients, but when the client SW starts,
it should read an XML-file common to the entire system, which would specify
(based on some unique ID of the client PC, like one IP address, or a MAC
address or the name of the computer) which processes should be possible to
start on this client PC, and also when, in a larger startup sequence, that
client should start it's process(es).

Hence I think I am stilling trying to solve the overall problem the rigth
way. So if you know how to get to the IP-adress(es) of the PC from Java, I
would be really greatfull.
