Is there a way that my local machines that has address like 192.168.0.1 can talk to my local machines that has address like 10.0.0.1. All machines are in my local network?

Do you have a router or does one of the systems have two network adapters? Any particular operating systems involved? –  HABO Aug 26 '12 at 14:00
    
Umm... Why don't you use the same sub network for all your machines? Either switch all to 192... or all to 10... –  terdon Aug 26 '12 at 15:07

Even though they may be physically on the same network, 10.x.x.x and 192.168.x.x are different networks. You need something route traffic between them, like a router.

A problem you may run into is that both 192.168.x.x. and 10.x.x.x are considered non-routed addresses on the Internet (that's why people use them for personal networks), so a router may not be willing route these addresses.

I agree with @techie007: "You need something [to] route traffic between [your networks], like a router."  However, this doesn't have to be a thing that has the word "Router" printed on it; it can be one of your computers.  (I assume that your "machines" are computers.)  You need to have at least one machine with two IP addresses: one on each of your networks.  If you happen to have a machine with two physical network interfaces, this should be straightforward.  Otherwise, you can (probably) assign multiple addresses to a single physical network interface.  In Windows, you can do this through the Control Panel.  (You will need to dig down a few levels; e.g., go to IPv4 Properties and then click on Advanced.)  In *nix you can use an ip or ifconfig command.  Then enable routing in that machine.  And you may need to tell the other machines to use this one as a router.

It would help us to answer your question if you would say what operating system(s) your machines are running.
