Please note:
- The prompts will tell you where to execute the commands, "
Tru64#" (root user) or "Linux#" (root user) - Remember Linux/Unix is case sensitive
- If hosts are not known by each other, fill the
/etc/hostsfile for example (usingvifor example) - linuxhost represents the name of your CHARON server (can be any name you want)
- tru64host represents the hostname of your Tru64 virtual machine
- Generate the key
→ Do not specify a passphrase |
...
If trying to execute a remote command on the Tru64 system, a message telling "no matching cipher found" is displayed, the cipher has to be setup on the Linux server side in the /root/.ssh/config file:

To facilitate use of "expect" for shutdown, an example is provided in the "guest_shutdown.exp" script located in the /opt/charon/utils folder. If you plan to customize the script, you'll have to create a copy and not use it directly as it will be overwritten in case of Toolkit upgrade.
Please note:
'telnet' and 'expect' packages must be installed in order to use this feature.
The following error message can be returned when stopping the virtual machine when trying to use the expect script example:
- if expect package is not installed: "
Stop script returned error code 126". - if telnet is not installed: "
%EXPECT-F-NOSRM, Cannot continue, 'telnet' is not installed" then "Stop script returned error code 4"
Caution: the virtual machine process will be however killed by service management process

If console is locked:
Any active session to the console must be killed before the "expect" script is executed.
For example, if you are connected via "telnet" on the localhost/port (the kill is not done inside the expect script). Using the "/opt/charon/utils/charon_gstart_expect" script file the necessary operations will be performed.
If the console is locked from another host (if you use putty for example), you will have to cancel the connection by yourself otherwise the shutdown will not be performed cleanly.
This script can handle the following situations:
