I've a crazy problem.
Installed Jboss-3.2 on two different machines: the first one with Windows XP, the other one with Linux Mandrake 10.
Create a test application which seems to work properly on both machines with local clients.
The problem is when I try to use clients on remote machines: the Windows version works fine, while the Linux version doesn't supply its EJB's to remote clients. The returned Exception is:

java.rmi.NoSuchObjectException : no such object in table

Note that the Linux machine is perfectly reachable from the outer world, all the servers (http, mysql...) work properly; the jmx-console is reachabe too, ad indicates that the required class is bound.
