ModeDescriptionRequirementsNotes
telnet

Telnet to the guest operating system using credentials stored in an encrypted clixml file.

This mode requires the Windows telnet client to be installed. This can be done using the following command:

C:\Charon> pkgmgr /iu:"TelnetClient"


  • OpenVMS only, does not work with Tru64.
  • If the password of the guest operating system changes, the encrypted clixml file has to be updated.
expectSimulates an interactive connection to the console of the CHARON instance and performs the necessary actions.


Warning
titleRestrictions

Expect is supported only on Windows Server 2008 R2 and Windows 7. Windows Server 2012 R2, Windows Server 2016 and Windows 8.1 and 10 are not supported.

  • Download and install TCL from http://www.activestate.com/activetcl/expect. Select the "x86" version, not "x64" as 'expect' is not included in the "x64" kit. Do not install a package version higher than ActiveTcl8.6.4.1.299124-win32-ix86-threaded as the Expect kit could be missing. This kit can also be downloaded here.
    Open a command window (cmd.exe), go to c:\tcl\bin and run:

    C:\tcl\bin> teacup install Expect

    (warning) Case sensitive: 'Expect' must be entered as shown (not 'expect').
    .

  • Download plink.exe from the www.putty.org web site: click on the "You can download PuTTY here." link and copy plink.exe to the same folder (recommended) as the Powershell and Expect scripts (C:\Charon for example).
  • Does not work if the console is running an application. Works only if the console is at the SRM prompt, prompting for username or password, or at the shell prompt.
  • Does not work if a connection to the console is already active from another host than the CHARON server.
  • If the password of the guest operating system changes, either the encrypted clixml file has to be updated or the password stored in clear text in the configuration file.
  • Useful if TCP/IP is not available on the guest operating system running on the CHARON instance.
rsh

Executes a remote command on the guest operating system (TCP/IP is required).

On Tru64 the .rhosts file must be configured and on OpenVMS the rexec/rsh services must have been enabled and a proxy must have been created.

The 'rsh.exe' file is included in the kit. Copy it to a folder of your choice ("C:\Bin" or "C:\Charon" for example).
  • Not subject to password change.
ssh

Executes a remote command on the guest operating system over a secure connection (TCP/IP is required).

Download and install OpenSSH from the https://github.com/PowerShell/Win32-OpenSSH/releases web site or preferably the version attached to this document.

(info) The (lightbulb) If the installation is menu driven, use the default options. If there's no menu driver installation, perform the following steps:

  • As the Administrator, extract the package to C:\Program Files\OpenSSH
  • As the Administrator, install sshd and ssh-agent services:
Code Block
powershell.exe -ExecutionPolicy Bypass -File install-sshd.ps1


  • Not subject to password change.
  • Secure connection.
