echo $SSH_CONNECTION does not display anything on the SSH server. I use my laptop to connect to my server using a key-less SSH setup. After SSHing to my server, if I run echo $SSH_CONNECTION in a terminal on the server from the machine itself I'm supposed to see the IP address and port numbers of my remote and local server client, however nothing is displayed. I am wondering if anyone can guide me in fixing this issue?
I have Ubuntu 16.04 running on both machines.

Perhaps you can edit to be clearer here, but I think that sounds normal if you're saying thatSSH_CONNECTIONis only set from within the SSH session. If that's not what you're saying then edit to break it down into what you see, where, and what you expected.

The SSH_CONNECTION environment variable will be set in the SSH session. It will not be set for any other process on the SSH server than for those started from the SSH connection from the client.
If you are logged in directly on the SSH server (on the physical machine, not through SSH), and type echo $SSH_CONNECTION, then I'm expecting that to output nothing.
So, logging in with SSH and then printing the value of $SSH_CONNECTION ought to look something like
[client] $ ssh username@server.example.com
[server] $ echo "$SSH_CONNECTION"
xxx.xxx.xxx.xxx nnnnn yyy.yyy.yyy.yyy 22
Where x is your client's IP address, n is the port used on the client, and y is the server's IP address.
