how to get remote system properties

[peer mohamed]

Hi,
by using System.getProperties() i can get the details of my machine.Is there any way by which i could find the details of a remote host.
thanks in advance
Peer

No. Only a JVM running on a machine can get at those properties, and even then a security manager might not allow it. Not to mention the fact that some of those properties depend on the runtime environment; without one, they have no fixed meaning.

In Java5 the JConsole uses new (and old?) APIs to get things like the following. You should be able to use them, too. I chopped this up a bit because it was over 4k characters wide ...
