<p>No. If the keys have been generated correctly (sufficient entropy etc) and independently (whether on the same machine or on different machines) then knowledge of one private key leaks no information on the other.</p>

<p>Just for curiosity, considering that there is a server communicating with other machine (local machine let's call it).

No. If the keys have been generated correctly (sufficient entropy etc) and independently (whether on the same machine or on different machines) then knowledge of one private key leaks no information on the other.
