Is it possible to find out the serial number of a server (OS X or

The reason I need to do this is to register an application for a
customer to only run on one machine, so perhaps there are other
ways, prewritten frameworks to do this.
Thanks

The traditional way of doing this on UNIX is look at the MAC address
of the Ethernet device en0. This is no good to you as it won't work
on Windows and, while Java provides eg java.net.NetworkInterface,
this class doesn't provide API for returning the MAC address.
Serial numbers of computers, operating systems, bit of software? Not
going to work well on both MacOSX[Server] or Windows, either. The
MacOSX system call gethostid() was removed some time ago because of
privacy concerns. Until recently, the WebObjects license key string
( /System/Library/Frameworks/JavaWebObjects.framework/Resources/
License.key ) might have been useful, but because of licensing
changes, we should no longer expect this file's contents to be unique
per machine.
If this is for one machine per customer, you can probably lock
against the local network address; try
java.net.InetAddress.getAllByName("localhost").
