CLI - User and Session

User

The user in the CLI means a user account that can directly connect to the imRAD devices using a console or ssh.

Verifying User and Login Sessions

You can verify all user list by the show user command. The "logged-in" indicates that someone is logged in or not. The "Password Aging" is used to forcibly change the password of users periodically. You can see the below message after login when you log in with an account whose password has been last changed the specified day(i.e. "Password aging") ago. In other words, we inform you to change the password of accounts every "Password aging" day.

We recommend that you should change your password because your password was changed 0 days ago. Would you like to change it?(y/n):

LYSH@MyHostName# show user
user         locked   logged-in    latest                            Last password change    Password Aging

If you enter the show session command, you can see all login sessions.

LYSH@MyHostName# show session

Configuring Password

You can change the password of the user by entering the user password command in the configuration mode. If you execute the user password command, the system will ask for the current password and new password.

LYSH@MyHostName# configure
configure# user password

Disconnecting User

You can forcibly disconnect a user session by the disconnect {tty} command in the user mode. you should ensure the tty of a user session by he show session command before disconnecting a session.

LYSH@MyHostName# disconnet pts/2

USER             TTY      FROM             LOGIN@   IDLE   JCPU   PCPU
ladmin           pts/1    192.168.0.11     Mon10    0.00s  2.56s  0.25s

Adding User

In the configuration mode, you can create a new user. Also, you can delete, lock, or unlock an existing user.

LYSH@MyHostName# configure
confiugre# user add newuser newpassword
confiugre# exit
LYSH@MyHostName# show user
