The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

The text-based user interface (TUI) provides a console-based interface for use by system installers, administrators, and troubleshooting personnel. The TUI replaces the requirement for any low-level system command line (shell) access and performs routine system tasks such as modifying system configurations, changing passwords, and checking system logs. Remote TAC access and troubleshooting can both be done from the TUI in the event of an outage or failure.
This section includes the following topics:
■Working with the TUI Interface
The TUI is a nested structure of menus with options that allow you to drill down to specific system tasks to perform on the server. The primary menus are:

Figure 1 TUI Map for Cisco Vision Dynamic Signage Director Servers
The Main Menu displays when you log in. To navigate through the menus, type the character that corresponds to the menu area item (a, b, c, and so on) and press Enter.
To return to other menus, use one of the indicated keys to return you to prior menus.
Caution: Avoid pressing Ctrl-c from the TUI. If services were started during the session they might stop running. Use the TUI menu system to exit the interface.
Several of the TUI options open server system files for you to modify using the Unix system vi editor. The following configuration files are editable from the TUI:
■DNS information—/etc/resolv.conf
■NTP server information—/etc/ntp.conf
■Server host information—/etc/hosts
Before modifying configuration files, you should be familiar with the simple editing techniques used within the vi editor. Table 2 describes some of the more common vi editor commands.
This section provides information about how to use some of the areas of the TUI interface. It includes the following topics:
■Displaying System Information
To access the TUI, use either physical console access or an SSH client such as PuTTY.
–Access the server using a directly-attached console.
–In the SSH client software, specify the IP address of the server that you want to access.
2. When the “login as:” prompt appears, type installer and press Enter (Figure 2):
3. At the password prompt, type the installer password and press Enter.
Note: In a PuTTY terminal, the keystrokes for your password entry are not shown.
When the login is successful, the Main Menu displays along with some basic system information at the top of the screen (Figure 3).

Note: Once logged in, you can change the installer password from the System Accounts > Change installer password menu option.
Note: Keep a good record of the changed installer password. Cisco cannot recover the password, If you lose the password, a re-install could be required.
The System Settings > System Information option allows you to obtain information about the current network configuration, hosts file, DNS configuration, NTP server, system date and time, and UUID for the server.
To display system information:
2. Choose System Settings and press Enter (Figure 3).
3. From the System Settings menu, type the letter corresponding to the System Information option and press Enter.
Caution: Avoid pressing Ctrl-c from the TUI. If services were started during the session they might stop running. Use the TUI menu system to exit the interface.
Note: If you are in a TUI submenu, type R or < or , and press Enter to go back to the Main Menu.
