4.5 Changing the ‘root’ and ‘taitnet’ Passwords
Tait networks are deployed with default weak passwords and it is the
responsibility of the client to change them to strong passwords.
To change the password of a user, login as that user and enter:
passwd
You will be prompted to re-enter your current password. Next you will be
asked to enter the new password that you wish to use. You will then be
asked to confirm the new password.
