Output

To hide administrative accounts from being listed, you can modify the `/etc/login.defs` file to set a UID range for system/administrative accounts that won't be displayed. Here are a few methods: 1. Edit `/etc/login.defs`:

# Set the UID_MIN to a higher number (e.g., 1000)
UID_MIN 1000

# Accounts with UIDs lower than 1000 will be hidden

2. Use PAM configuration by editing `/etc/passwd.conf`:

invisible=0-999

3. For display managers (like GDM, LightDM), you can: - Create/edit `/etc/lightdm/users.conf`:

[UserList]
minimum-uid=1000
hidden-users=root admin administrator

4. For specific users, you can also modify `/etc/shadow`:

# Add a ! at the beginning of the password field
admin:!$6$hash....:18000:0:99999:7:::

5. Another option is to create a `/etc/gdm3/greeter.dconf-defaults`:

[org/gnome/login-screen]
disable-user-list=true

Remember to: - Backup configuration files before making changes - Use `sudo` or root privileges to make these modifications - Restart the display manager or system after changes - Test the changes to ensure they work as expected Choose the method that best fits your specific Linux distribution and requirements.

Output

To hide administrative accounts from being listed to regular users, you can modify the `/etc/login.defs` file and use the `HIDDEN_SHELLS` directive. Here are a few approaches: 1. Using `/etc/login.defs`:

# Add this line to /etc/login.defs
HIDDEN_SHELLS=/etc/shells.hide

Then create `/etc/shells.hide` and list the shells used by administrative accounts:

/sbin/nologin
/bin/false

2. Alternatively, you can modify `/etc/passwd` to: - Give administrative accounts UIDs less than `UID_MIN` (typically 1000) - Use special shells like `/sbin/nologin` or `/bin/false` 3. You can also modify `/etc/shadow` to: - Add an '!' or '*' at the start of the password field 4. For desktop environments, you can hide users by creating/editing `/etc/gdm/custom.conf`:

[daemon]
Exclude=admin1,admin2,root

5. Another approach is to create `/var/lib/AccountsService/users/USERNAME` files:

[User]
SystemAccount=true

Best practices: - Keep administrative account UIDs below 1000 - Use `/sbin/nologin` or `/bin/false` as shells for service accounts - Consider using PAM configuration to restrict user listing - Regularly audit account visibility and access Remember: These methods help hide accounts from casual viewing but don't provide security by themselves. Always implement proper access controls and security measures.

Output

To hide administrative accounts from being listed on Linux systems, you can use several methods: 1. Modify /etc/login.defs: Add or modify the USERGROUPS_ENAB parameter:

1	USERGROUPS_ENAB no

2. Set the UID range for hidden users in /etc/login.defs:

UID_MIN 1000
UID_MAX 60000

Users with UIDs below 1000 won't be shown in most user lists. 3. Modify /etc/passwd: Make sure administrative accounts have UIDs below 1000. 4. For GUI login screens (like GDM, LightDM): Create or edit /etc/gdm3/greeter.dconf-defaults (for GDM):

[org/gnome/login-screen]
disable-user-list=true

5. Hide specific users by creating/editing /etc/gdm3/custom.conf:

[greeter]
Exclude=admin1,admin2,root

6. For LightDM, edit /etc/lightdm/users.conf:

[UserList]
hidden-users=admin1 admin2 root
minimum-uid=1000

7. Apply changes:

# For GDM
sudo dpkg-reconfigure gdm3

# For LightDM
sudo systemctl restart lightdm

These methods will help hide administrative accounts from regular user listings while maintaining their functionality. Choose the method(s) that best suit your needs and desktop environment. Remember to: - Keep track of hidden accounts - Test the changes before implementing widely - Ensure administrative access is still possible - Document the changes for future reference

Output

To hide administrative accounts from being listed, you can modify the `/etc/login.defs` file and create or modify `/etc/shadow-` to specify which user accounts should be hidden. Here are a few methods: 1. Using UID ranges:

# Edit /etc/login.defs
# Set UID_MIN to a higher number than your admin accounts
UID_MIN 1000

Any account with a UID lower than 1000 won't be shown in most user listing utilities. 2. Using `/etc/shadow-`:

# Create or edit /etc/shadow-
# Add the usernames you want to hide, one per line
admin_user1
admin_user2

3. For the GNOME desktop environment:

# Edit /var/lib/AccountsService/users/[username]
[User]
SystemAccount=true

4. You can also modify `/etc/passwd` to set the shell to `/sbin/nologin` for accounts you want to hide:

1	admin_user:x:999:999::/home/admin_user:/sbin/nologin

5. For hiding users from the login screen, you can modify `/etc/gdm3/daemon.conf`:

[security]
Exclude=admin_user1,admin_user2

These methods can be used individually or in combination depending on your specific needs and the Linux distribution you're using. Note: Regular users can still potentially see these accounts using certain commands like `getent passwd`, so these methods provide basic hiding rather than complete security.

Output

To hide administrative accounts from being listed, you can modify the login display settings in several ways: 1. Using /etc/login.defs: Add or modify the following line:

USERS_TO_HIDE root,admin1,admin2

2. Using /etc/passwd: For accounts you want to hide, set the UID to be less than the UID_MIN value in /etc/login.defs. By default, most systems only display users with UIDs of 1000 or greater. 3. Using /etc/shadow: You can prevent login listing by adding a '!' at the beginning of the password field for those accounts. 4. Using PAM configuration: Modify /etc/pam.d/login to hide specific users:

auth required pam_nologin.so successok
auth [success=1 default=ignore] pam_succeed_if.so user notingroup admin

5. For display managers (like GDM, LightDM): Create or edit /etc/lightdm/users.conf:

[UserList]
hidden-users=root,admin1,admin2
minimum-uid=1000

The most common and straightforward approach is using the UID method (#2). Just ensure the administrative accounts have UIDs below 1000. Remember to backup any files before making changes!
