Command Execution and Data Forwarding

After authentication is complete, the user can use Solaris Secure Shell, generally by requesting a shell or executing a command. Through the ssh options, the user can make requests, such as allocating a pseudo-tty, forwarding X11 connections or TCP/IP connections, or enabling an ssh-agent over a secure connection. The basic components of a user session are as follows:

1. The user requests a shell or the execution of a command, which begins the session mode.

   In this mode, data is sent or received through the terminal on the client side, and the shell or command on the server side.

2. The user program terminates.

3. All X11 forwarding and TCP/IP forwarding is stopped. Any X11 connections and TCP/IP connections that already exist remain open.

4. The server sends the command exit to the client, and both sides exit.
