Security and Passwords
The IT51E terminal uses two passwords, the PIN (Personal Identification Number) and the remote Login
password. This section explains their purpose and how you can change them.
The Terminal PIN
You need to enter the PIN at the terminal to access the Terminal Setup (see
“Accessing the Terminal Setup”
).
The factory default PIN is 1905. We recommend that you change this as soon as possible to ensure security
of the terminal.
There are two ways to change the PIN:
You can change it from the Change PIN option on the terminal’s Firmware setup menu. See
. You must first re-enter the old one.
You can also change the PIN on the command line. For example, to change the PIN to 12345, enter the
following command:
$ cfgset –p it_cfgit_pin 12345
The Login Password
The terminal Login password is used by SSH and FTP to log in into the system. It can only be changed from
the terminal’s shell, for example using SSH.
By default no password is set. We recommend that you set a password as soon as possible to ensure
security of the terminal.
To change the password on the command line, enter a command of the following format:
$ cfgset –p it_login new_password
We recommend a minimum password length of 6 characters which may include digits.
For the password to become active you must either:
Reboot the terminal, or
Run the following command:
$ sh /etc/init.d/S38passwd.sh restart
Note: When using the
cfgset
command to save a new password or PIN, you must use the
-p
option as the
terminal saves the password in an encrypted form. If the password is lost then it may result in the terminal
being reset to its factory default state. In this case all user data on the terminal will be destroyed. See
“Recovering Lost Passwords” on page 27
