• "telnet" package must be installed, it will be used to connect from the CHARON server to the virtual machine console
• The session will be recorded in a log file:
  • If 'set OPA0 log=' is found in the configuration file (not available with all CHARON products versions), the log will be stored in the temporary folder: '/tmp/console.<configuration file name shortened>.tmp.log' and will be overwritten for each session. It is just kept for information as the console log is managed by the CHARON emulator itself. For Charon-AXP and Charon-VAX version 4.9 and above, the line "set COM1 alias = OPA0 port = <port>" (new syntax) is also checked.
  • If there is no 'set OPA0 log=' line in the configuration file, the file will be located in '/opt/charon/log/console.<configuration file name shortened>.log'
• If 'stop_on' and/or 'break_on' features are enabled in the configuration file, this will be reminded before starting the telnet session

• To leave the telnet session, press the escape character which is by default CTRL + ] . This character can be changed in the /root/.telnetrc file by defining the 'set escape' parameter:
  Example:

  # cat /root/.telnetrc DEFAULT   mode   mode char   set   set escape ² #

  Pressing the escape key will lead you to the 'telnet> ' prompt. To leave the session, enter 'quit'

• If a connection to the console is active from the server, you will be prompted to kill the previous one.
• If a connection to the console is active from another location, it will be displayed but will not be killed. This will have to be done manually.
• Emulator termination check:
  
  • For CHARON-AXP, if the 'power off' command is detected (or shortened command), the guest STOP state will be set to REQUESTED. If a telnet connection to the console is performed without this utility, the REQUESTED state will not be set.
  • If the emulator is no more running when you leave the session, you will have to confirm that is requested or not
• The console port number is displayed per guest. If a port number is used more than once, an alert will be displayed
