expect | Requires you pass user and password to the script so that it can connect to the console via "telnet" and execute the shutdown commands. The "guest_shutdown.exp" script, located in the /opt/charon/utils folder, can perform operations to: - run the shutdown if the prompt is detected,
- enter a username/password to login if "Console L
ogin:" is detected, - execute the shutdown command if the prompt is detected,
- detect the Main Menu or ISL prompt to issue the "
exit" command.
This method is useful if the virtual machine has no telnet connection available and cannot handle "rsh" and "ssh" remote connections. For more, please read Tips and Tricks - Shutdown guests with Expect tool. Important notes: - For MPE/iX systems, this is the only available method. Username and password are then not necessary. Two A <CTRL-A> will be sent on the console then if the "=" prompt is detected the "SHUTDOWN SYSTEM" command will be sent .(other cases are also taken into account like Main menu prompt, ISL> prompt or text garbage on the console)
- Note any local existing connection to the console has to be killed before executing the expect script.
- If the console is locked from an external connection or if the prompt is not detected after sending a carriage return, the expect script will fail.

rsh | Requires a trust to be created between the Linux server and the HP-UX guest to issue password free remote commands. For more, please read the Tips and Tricks chapter dedicated to rsh trusts. |
ssh | Requires a secured trust to be created between the Linux server and the HP-UX guest (key pair) to issue password and passphrase free remote commands. For more, please read the Tips and Tricks chapter dedicated to ssh trusts. |

When the script is initialized using option 6 or when a new virtual machine is added, the following lines are added:
... # Parameter $1: contains full path to cfg file
# Parameter $2: contains full path to emulator exe file

# Important notes:
# - comments & commands must be on separate lines
# - respect the structure of the file with case/in/esac
# - only place your commands between the selection and the ';;' line
