Getting Started with Linux Fundamentals

Instructions

1. On the fourth virtual console, update the developer1 user's password. Set lab2-rh104-1 as the new password.

   1. Switch to the fourth virtual console by pressing Alt+Ctrl+F4. Log in as the developer1 user and use redhat as the password.

   2. Review the passwd command help information. The --help (or -h) option prints information about the command itself, and the options you can use to alter the command's outcome.

      [developer1@workstation ~]$ passwd --help
      Usage: passwd [OPTION...] <accountName>
        -k, --keep-tokens       keep non-expired authentication tokens
        -d, --delete            delete the password for the named account (root only); also removes password lock if any
      ...output omitted...

   3. Update the developer1 user password to lab2-rh104-1. Use redhat as the current password.

      [developer1@workstation ~]$ passwd
      Changing password for user developer1.
      Current password: redhat
      New password: lab2-rh104-1
      Retype new password: lab2-rh104-1
      passwd: all authentication tokens updated successfully.

   4. Test the new password by closing the session and logging back in.

      [developer1@workstation ~]$ exit
      
      workstation login: developer1
      Password: lab2-rh104-1
      [developer1@workstation ~]$

   5. Close the virtual console session.

      [developer1@workstation ~]$ exit

   6. Return to the desktop session by pressing Alt+Ctrl+F2.

      $ Alt+Ctrl+F2

3. Ensure that the machine time clock is synced with a time server.

   1. Review the system clock by using the date command.

      [student@workstation ~]$ date
      Fri Sep 29 14:24:58 EDT 2023

      The information given by the date command is not enough to determine whether the system clock is synced with a time server.

   2. Review the system clock by using the timedatectl command.

      [student@workstation ~]$ timedatectl
                     Local time: Fri 2023-09-29 14:25:56 EDT
                 Universal time: Fri 2023-09-29 18:25:56 UTC
                       RTC time: Fri 2023-09-29 18:25:56
                      Time zone: America/New_York (EDT, -0400)
      System clock synchronized: yes
                    NTP service: active
                RTC in local TZ: no

      The output shows that the system clock is synced with a time server.
