Authorize SSH Access to the VCH Endpoint VM

You can use the vic-machine debug command to enable shell access to a virtual container host (VCH) endpoint VM by setting a root password on the VM. Setting a root password enables access to the VCH endpoint VM via the VM console. You can also use debug to authorize SSH access to the VCH endpoint VM. You can optionally upload a key file for public key authentication when accessing the endpoint VM by using SSH.

IMPORTANT: Any changes that you make to a VCH by using vic-machine debug are non-persistent and are discarded if the VCH endpoint VM reboots.

For descriptions of the options that vic-machine debug includes in addition to the Common vic-machine Options, and for information about password expiry periods, see VCH Debug Options.


You deployed a VCH.


  1. On the system on which you run vic-machine, navigate to the directory that contains the vic-machine utility.
  2. Run the vic-machine debug command.

    • Specify the vSphere target and its credentials, either in the --target option or separately in the --user and --password options.

      The credentials that you provide must have the following privilege on the endpoint VM:

      Virtual machine.Guest Operations.Guest Operation Program Execution

      • Specify the ID or name of the VCH to debug.
      • Potentially provide the thumbprint of the vCenter Server or ESXi host certificate. Use upper-case letters and colon delimitation in the thumbprint. Do not use space delimitation.
      • Specify the --rootpw option. Wrap the password in single quotes (Linux or Mac OS) or double quotes (Windows) if it includes shell characters such as $, ! or %.
      • Authorize SSH access by specifying --enable-ssh.
      • Optionally, specify the --authorized-key option to upload a public key file to /root/.ssh/authorized_keys folder in the endpoint VM. Include the name of the *.pub file in the path.
      $ vic-machine-operating_system debug
      --target vcenter_server_or_esxi_host_address
      --user vcenter_server_or_esxi_host_username
      --password vcenter_server_or_esxi_host_password
      --id vch_id
      --thumbprint certificate_thumbprint
      --rootpw 'new_p@ssword' 
      --authorized-key path_to_public_key_file/


The output of the vic-machine debug command includes confirmation that SSH access is enabled:
