GNU Linux Command similar to QNX "ditto"

I used to work on a bunch of QNX machines and used a utility called "ditto". It is not the same as GNU Linux "ditto". This is from the QNX documentation:

View or control another console (QNX)

The ditto utility allows a user to attach their local console or terminal to a remote console. While attached, the local screen reflects the contents of the remote screen, and any changes made to the remote screen are updated on the local one. When the keyboard is enabled, key strokes entered by the user of ditto are "injected" into the remote console, as if typed directly by the remote user.
It was really handy because I could access any console on any machine on the lan from which ever machine I happened to be sitting at.

Is there a similar utility for GNU Linux, specifically Debian?

I don't know if it's only me but I have a hard time understanding what you mean. Can you clarify with a more detailed example please? I don't know QNX nor the ditto command on it but connecting from one machine's terminal to another (remote) terminal is just a SSH connection, or are you referring to something completely different?

Kind regards,

You cannot directly do what you're trying as it violates Linux's security model, however you can implement screen to allow a session to be concurrently shared by multiple users. It requires that screen be used on the target terminal and that screen be set up in multi-user mode.
