You can check for the IP.

Now, you listen and accept incoming connections. On accept launch a new thread
and you can accept as many connections (creating as many sockets) as you
want. You'll have to limit it to two of course. I'd code this as two
gen_servers, one the launcher, listening for incoming connections and keeping
track of who connected and how many times and then another to handle the
connection itself (hint: there's a function to reassign the ownership of the
socket to a new process).

Have you coded a simple server first ? I'd recommend to star there.

You can do reading and witting on the same socket, on the same connection. It
has been that way for what ? 20 years ? 30 years ?
