A more interesting use case is actually the opposite ssh user@host -R 127.0.0.1:4000:127.0.0.1:3000 in this case you can expose a local only service (3000) as a service on the "host" on port 4000, you could do also *:4000 to accept any incoming connections on the "host" but may need some configuration on the ssh server.

One case I didn't find a tool yet, is when you want to be sure that all the software installed on your system is actually from a debian package, that is the source I trust, potentially the system can have a binary installed in a executable path of the system and be executed without any source check, even debsums checks only the binaries of the installed packages, but it does not report binaries that do not come from a package.

Like the previous post explain I'm working on this project ( Object Query ) to find a new way to write DBMS query directly in java.
So my idea is not so hard to implements until you are thinking in Object way, like almost all java think, but there are few things that in java are not object one of this are the primitives types, and this primitive types are common in an DDD domain that's mean if I'm not able to handle this problem my idea is died!

So now i have to start to think to a good solution:
What I've in my project is a pure java domain, and a proxy instance of a class of domain, so i can just start from this point to try to solve my problem.

Another start point for try to solve this problem is the java (from 1.5) behaviour, that allow to to transfer primitive type values in an object way through code, wrapping it in an specific object(java.lang.Integer,java.lang.Long, etc..) this is called boxing.

So i can try to create an my owned boxing object to use for handle primitive types, this i think is not hard just define an api that receive primitive type and return an object that represent the path of primitive type call. with a code like this:

	Object primitiveBoxed = query.box(proxy.getHome().getWeight());

OK I can solve my problem, just because when i call the method getWeight on my proxy a create a fake value to associate to path "home.weight",
and the call box() i receive the previous value and from this value i can extract the associate path and after create a "Boxing" object with associate path.
after this operation I've an object with associate the path like a normal object.

So i found i way to solve the problem of primitive values .... and i just implemented it !!
wonderful!!
Done !!

When you try to develop a software following DDD principles you need to use some frameworks that help you to thinking only to domain, example the ORM for the persistence or user interface generator for the user interaction.
Now I want focus on persistence because in my work experience I found some gap in the persistence frameworks.

Explain the gap:
if you are using java probably you want define all rules and all behaviour of your domain using only java, and this is almost possible,
Just define a domain:

public class Person {
     private String name;
     private String surname;
     private Dog dog;
    //.... gets sets ...
}
