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 had been changed last before the specified day(i.e. "Password aging"). In other words, we inform you to change the password of accounts every "Password aging" day.
The default value of the "Password aging" is 30 days.
We recommend that you should change your password because the last time you changed your password exceeded the "Passowrd aging". Would you like to change it?(y/n):
LYSH@MyHostName# show user user locked logged-in latest Last password change Password Aging ladmin True True Wed Apr 28 17:55:44 +0900 2021 Apr 23, 2021 30 days
If you enter the show session command, you can see all login sessions.
LYSH@MyHostName# show session 18:58:08 up 86 days, 10:51, 4 users, load average: 0.09, 0.14, 0.15 USER TTY FROM LOGIN@ IDLE JCPU PCPU ladmin pts/1 192.168.0.11 Mon10 0.00s 2.56s 0.25s ladmin pts/2 192.168.0.11 Mon10 1:02m 0.53s 0.41s
Login History
If you enter the last command on user mode, it shows listing of last logged in users. The lastb command shows all the bad login attempts(e.g. incorrect user or password).
LYSH@MyHostName# last ladmin pts/1 192.168.5.11 Thu May 20 10:29 still logged in ladmin pts/0 192.168.5.11 Thu May 20 10:26 still logged in ladmin pts/0 192.168.5.13 Tue May 18 18:03 - 18:37 (00:33) ladmin pts/0 192.168.5.15 Tue May 18 17:04 - 17:46 (00:42) ladmin pts/3 192.168.5.15 Tue May 18 12:19 - 15:55 (03:35) ..... LYSH@MyHostName# lastb adsdf ssh:notty 192.168.5.11 Thu May 13 18:08 - 18:08 (00:00) ladmin ssh:notty 192.168.5.11 Thu May 13 18:03 - 18:03 (00:00)
If you enter man last or man lastb command on user mode, you can see the manual of them.
Configuring Password
You can change the password of the user by entering the user password {user} command in the configuration mode. If you execute the user password {user} command, the system will ask for the current password and new password.
LYSH@MyHostName# configure LYSH@MyHostName(config)# user password ladmin
Disconnecting User Session
You can forcibly disconnect a user session by the disconnect tty {tty} command in the user mode.
you should ensure the tty[1] of a user session by he show session command before disconnecting a session.
LYSH@MyHostName# disconnet tty pts/2 18:58:08 up 86 days, 10:51, 4 users, load average: 0.09, 0.14, 0.15 USER TTY FROM LOGIN@ IDLE JCPU PCPU ladmin pts/1 192.168.0.11 Mon10 0.00s 2.56s 0.25s ladmin pts/2 192.168.0.11 Mon10 1:02m 0.53s 0.41s
Adding User
In the configuration mode, you can create a new user. The "Password Aging" will be set to 30 days as default.
LYSH@MyHostName# configure confiugre# user add newuser newpassword confiugre# exit LYSH@MyHostName# show user user locked logged-in latest Last password change Password Aging ladmin True True Wed Apr 28 17:55:44 +0900 2021 Apr 23, 2021 30 days newuser True False **Never logged in** Apr 29, 2021 30 days
Deleting User
To delete a specific user, enter the user delete {user} command in the configuration mode.
if you delete a user who is in a login state, you will fail to delete it. Therefore you must disconnect the user before deleting it.
LYSH@MyHostName# configure confiugre# user delete newuser
lock/unlock
You can lock a user. And then you can't log in with the locked user. Also, you can unlock the locked user.
LYSH@MyHostName# configure confiugre# user lock newuser LYSH@MyHostName(config)# exit LYSH@MyHostName# show user user locked logged-in latest Last password change Password Aging ladmin True True Wed Apr 28 17:55:44 +0900 2021 Apr 23, 2021 30 days newuser True False **Never logged in** Apr 29, 2021 30 days LYSH@MyHostName# configure confiugre# user unlock newuser LYSH@MyHostName(config)# exit LYSH@MyHostName# show user user locked logged-in latest Last password change Password Aging ladmin True True Wed Apr 28 17:55:44 +0900 2021 Apr 23, 2021 30 days newuser False False **Never logged in** Apr 29, 2021 30 days
Configuring Password Aging
You can change the "Password Aging" by entering the user passwordage {age} in the configuration mode.
Note that you can change the value only for the current user.
LYSH@MyHostName# configure confiugre# user passwordage 60 LYSH@MyHostName(config)# exit LYSH@MyHostName# show user user locked logged-in latest Last password change Password Aging ladmin True True Wed Apr 28 17:55:44 +0900 2021 Apr 23, 2021 60 days newuser False False **Never logged in** Apr 29, 2021 30 days
