This topic describes how to connect to the Delphix Engine command line interface.
If the same username exists in both the SYSTEM and DOMAIN namespaces (for example a sysadmin and a domain user), when logging in via ssh it is necessary for the user to explicitly provide the namespace SYSTEM or DOMAIN. For example, a user whose name exists in both namespaces must ssh in as either "someone@SYSTEM" or "someone@DOMAIN". If the user tries to log in as just "someone", the engine will give an error:
Ambiguous username. Add a @DOMAIN or @SYSTEM suffix to the username.
The CLI is available over SSH or the terminal console on any Delphix Engine version 3.0 or later. To connect, use any SSH client appropriate for your workstation environment and connect to the Delphix Engine by IP or hostname on the standard SSH port (22). Enter a username for either a domain or system user followed by the namespace appropriate to that user (either DOMAIN or SYSTEM). For example:
ssh admin@DOMAIN@delphix-server.example.com
ssh sysadmin@SYSTEM@delphix-server.example.com
At the prompt, enter your user password. Once connected, you will be placed at the CLI prompt:
delphix>
While both admin and sysadmin produce the same prompt once logged in, be aware that the two users have different menus and different functional areas.
Sysadmin Menu
delphix> ls Children network service storage system user Operations version Operations version delphix>
Delphix Admin Menu
delphix> ls Children alert audit authorization connectivity database environment fault group host job namespace network policy replication repository service session snapshot source sourceconfig system timeflow user Operations version delphix>
Individual commands passed as arguments to the SSH client will be interpreted as if they had been read from the terminal. More complex scripts can be passed as input to the SSH command. When running SSH in non-interactive mode via these mechanisms, the command line prompt will be suppressed, as will terminal font decorations such as underline and bold.
The CLI is also available from the serial terminal console should the network be unavailable. Consult your VM platform documentation for information on how to connect to the terminal console. Once connected, log in using your Delphix user credentials just as you would over SSH.
If the management service is unavailable due to a software bug or other problem, the CLI can still be accessed as a system user provided that user is locally authenticated (not via LDAP) and has logged in at least once before. While in this state, only the system commands are available, including restart, which will attempt to restart the management service without rebooting the entire server. If this problem persists, please contact Delphix support.
The topic CLI Cookbook: Configuring Key-Based SSH Authentication for Automation shows an example of how to connect to the CLI using SSH key exchange instead of the standard password-based authentication.
