22.3. SSH commands
	Chapter 22. SSH - Secure SHell

While the SSH Server process is running, the User can access the SSH resource commands by typing the combination Ctrl+P.

As a consequence of this action, the prompt of the SSH Server, configured in the parameter PSER, will be displayed.

The user can leave the command exchange procedure and start the data exchange by typing again the combination Ctrl+P.

The available commands for the command interpreter of the SSH resource are:

open: This command, available only on SSH client processes, allows the User to open a connection with the SSH Server process, hosting on the remote equipment identified by the specified IP.
close / exit: It requests the session to be closed.
clr: It requests the session to be closed.

22.3.1. SSH from Abilis to Abilis

To open an SSH session from an Abilis to another Abilis, the X.25 routing must be properly configured. Both Abilis must have the following X.25 routing:

Example 22.1. X.25 routing

[10:38:01] ABILIS_CPX:a r pr:3 in:ssh out:ssh cdi:* udi:ssh

COMMAND EXECUTED

[10:38:04] ABILIS_CPX:a r pr:4 in:* out:ssh cdi:* udi:ssh

COMMAND EXECUTED

[10:38:07] ABILIS_CPX:d r

-------------------------------------------------------------------------------

The routing with PR:3 allows to transfer an incoming SSH session to an outgoing SSH session, while routing with PR:4 allows to transfer any incoming session to an outgoing SSH session.

Some examples follow.
