show users

show user <UserName>

      [force-password-change]

      [gid]

      [homedir]

      [lock-out]

      [realname]

      [shell]

      [uid]

delete user <User ID>

Important - After you add, configure, or delete features, run the "save config" command to save the settings permanently.

Parameters

Parameter

Description

user <UserName>

Configures unique login username - an alphanumeric string, from 1 to 32 characters long, that can contain dashes (-) and underscores (_), but not spaces: a-z A-Z 0-9 - _

uid <User ID>

Optional. Configures unique User ID to identify permissions of the user:

homedir <Path>

Configures user's home directory.

This is the full Linux path name of a directory, to which the user will log in.

Must be a sub-directory of the /home/ directory.

If the sub-directory does not already exist, it is created.

force-password-change {yes | no}

If you wish to force the user to change the configured password during the next login, use the value "yes".

Note - If the user does not log in within the time limit configured by the "set password-controls expiration-lockout-days" command, the user may not be able to log in at all.

gid <System Group ID>

Configures System Group ID (0-65535) for the primary group, to which a user belongs.

The default is 100.

You can add the user to several groups.

Use the "add group" and "set group" commands to manage the groups.

lock-out off

Unlocks the user, if the user was locked out.

The password expiration date is adjusted, if necessary.

newpass <Password>

Configures a new password for the user.

Gaia does not ask to verify the new password.

The password you enter shows on the terminal command line in plain text, and is stored in the command history as plain text.

password

Configures a password for the new user.

The command runs in interactive mode.

You must enter the password twice, to verify it.

The password you enter is not visible on the terminal command line.

password-hash <Password Hash>

The password as an MD5, SHA256, or SHA512 salted hash instead of plain text (the password string must contain at least 6 characters).

Use this option when you upgrade or restore using backup scripts.

You can generate the hash of the password with the "cpopenssl" command (run: cpopenssl passwd -help).

To configure the default hash algorithm, see:

Best Practice - Do not use MD5 hash because it is not secure.

Notes:

  • Format:

    $<Hash Standard>$<Salt>$<Encrypted>

  • The length of this hash string must be less than 128 characters.

  • <Hash Standard>

    One of these digits:

    • 1 = MD5

    • 5 = SHA256

    • 6 = SHA512

  • <Salt>

    A string of these characters:

    a-z A-Z 0-9 . / [ ] _ ` ^

    The length of this string must be between 2 and 16 characters.

  • <Encrypted>

    A string of these characters:

    a-z A-Z 0-9 . / [ ] _ ` ^

    The length of this string must be:

    • For MD5, less than 22 characters.

    • For SHA256, less than 43 characters.

    • For SHA512, less than 86 characters.

realname <Name>

Configures user's description - most commonly user's real name.

This is an alphanumeric string that can contain spaces.

The default is the username with the capitalized first letter.

shell <Login Shell>

Configures the user's default login shell.

See the explanations in the "Login Shells" section below.
