That is pretty much the way ssh works -- to connect and communicate between
two machines with ssh, you put ssh software in each machine -- it just happens
that the software is slightly different, and one machine (and its software)
acts as a server and the other machine acts as a client.
In my home LAN, I use static IPs (ipv4) on each machine, so to do things on
the server from the client, I first login starting with a command like:
From a CLI on the client:
ssh <username on server>@<ip of the server>
e.g.,
ssh riveravaldez@192.168.1.35
I'm then prompted for the password of the user account on the server.
You can set up ssh for passwordless use.
If you don't have static IPs on your LAN, you have to get the IP by some means
which in any case, can include a domain name form, e.g., mylan.home
