Atop the same SSH session
other protocols may run.

For example:
- Port forwarding / tunneling protocol
- SFTP protocol
- X11 Forwarding protocol
- SSH Agen protocol
- etc.

All using one single TCP connection to port 22.

Hence is why SSH is a #SessionLayer protocol.

Do you #Morsecode? Forgot how #tcppacket break down. How about the #OSILayers? #geekonfleek @Hack3rRunway

The #SSH stack
is the best illustration
for the OSI 7 Layer architecture.

The SSH protocol itself is a Session-layer protocol
the $TERM is a Presentation-layer protocol
and the shell is the Application-layer protocol
