Certain features of BMC Atrium Discovery need command line access to configure. For example, the appliance obtains its IP address using DHCP by default, though you may configure it at the command line to use a static IP address.

Default Command Line Passwords

BMC Atrium Discovery is configured with the following default command line user accounts and passwords.

• root – tidewayroot
• tideway – tidewayuser
• netadmin – tidewaynetadmin

You should log in as root and change these passwords immediately.

To log in, use the VMware Server Console, or ssh in to the appliance using a terminal. Note that you cannot ssh into the appliance as the root user. First you must log in as the tideway user and su to root. When you have logged in, the first thing you should do is change the root and user passwords.

To Change the root and tideway Passwords

1. As the root user, use the passwd command to change the password.
2. Enter a new password when prompted. An example session is shown below:

# passwd
Changing password for user root.
New UNIX password: 
Retype new UNIX password:
passwd: all authentication tokens updated successfully.
# 

When you enter the new password it is not echoed to the screen.

1. Change the tideway user's password. Still logged in as the root user, change the password using the passwd command specifying the tideway user.
2. Enter a new password when prompted. An example session is shown below:

   # passwd tideway
   Changing password for user tideway.
   New UNIX password: 
   Retype new UNIX password:
   passwd: all authentication tokens updated successfully.
   # 

   The passwords are now changed.

The root user

The root user has unlimited privileges on the appliance and should only be used for the following tasks:

• Changing default passwords
• Upgrading the BMC Atrium Discovery application software
• Adding new disks to the appliance

Any other task on the appliance which typically would require a UNIX/Linux root user can be undertaken using sudo to temporarily grant additional privileges to the tideway user.

The tideway user

The tideway user is a powerful administrative account intended for performing virtually all of the tasks that would need to undertake using the command line. Examples of such tasks are:

• All command line utilities
• Customizations (taxonomy, reports, and visualizations)
• Managing log file (though this can be done through the UI)
• Starting and stopping services (with additional privileges accused through sudo)

Additional users

The following additional users are configured on the appliance:

• The migrate user
• The netadmin user
• The upload user
