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 Utility 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 can be used to perform routine system tasks such as modifying system configurations, changing passwords, and checking system logs. Remote TAC access and troubleshooting can both be facilitated from the TUI in the event of an outage or failure.
The Cisco Vision Dynamic Signage Director Director and Cisco Vision Dynamic Signage Director Remote servers both include a TUI interface. The remote server version of the TUI has a similar menu structure, but only provides a subset of the functions available in Cisco Vision Dynamic Signage Director.
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 be performed on the server. The primary menus are:

The Main Menu is displayed when you log in. To navigate through the menus you must type the character that corresponds to the menu area where you want to go (a, b, c, and so on) and press Enter.
To return to other menus, you must back out of the hierarchy of menus using one of the indicated keys to return you to prior menus.
Caution: Avoid pressing Ctrl-c from the TUI. This immediately terminates the TUI session and 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, you need either physical console access or an SSH client such as PuTTY.
To log into the TUI, complete the following steps:
–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 3):
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 is displayed along with some basic system information at the top of the screen (Figure 4).

Note: Once logged in, you can change the installer password from the System Accounts > Change installer password menu option.
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, complete the following steps:
2. Type a (for System Settings) and press Enter.
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. This immediately terminates the TUI session and if services were started during the session they might stop running. Use the TUI menu system to exit the interface.
To exit the TUI, complete the following steps:
Note: If you are in a TUI submenu, you will have to type R or < or , and press Enter to navigate back to the Main Menu.
