Symptoms

The admin account password has expired. Any commands requiring admin do not run correctly. For example: dpnctl status WARNING: Your password has expired. Password change required but no TTY available. Attempting to run the change-passwords script fails with the following error: For example: (the change-passwords command run in debug mode): change-passwords --debug --verbose dpn.pm::parse_flags_no_probe(); verbose=1, run=1, debug=1, ping_only=1, error=1 ] Using /usr/local/avamar/var/probe.xml Using /usr/local/avamar/var/probe.xml change-passwords: ERROR: no nodes in node set "0.s" responded change-passwords: ERROR: no IP address found for server (node 0.s) [change-passwords version 1.29] +++ WARNING: It is suggested that you quit this program, correct the problems for which the warnings were issued above, and then re-run change-passwords.

Cause

The admin terminal (TTY) is unavailable as the password expiration prevents access.

Resolution

1. As root, use the chage command to review the admin password information: chage -l admin Minimum: 1 Maximum: 60 Warning: 7 Inactive: -1 Last Change: Sep 28, 2022 Password Expires: Nov 27, 2022 Password Inactive: Never Account Expires: Never 2. Make note of the maximum age and password expiry values. 3. Increase the maximum age value to never expire using the following command: chage -M 99999 admin Aging information changed. 4. Confirm that the maximum age and password expires values have been updated. chage -l admin Minimum: 1 Maximum: 99999 Warning: 7 Inactive: -1 Last Change: Sep 28, 2022 Password Expires: Never Password Inactive: Never Account Expires: Never 5. Run the change-passwords script to update the passwords. 6. Return the password expiration values for admin back to its previous value (noted in step 2) In this example, it is 60 days: chage -M 60 admin Aging information changed. 7. Confirm that the password aging information has been updated to back to its previous values. chage -l admin Minimum: 1 Maximum: 60 Warning: 7 Inactive: -1 Last Change: Nov 30, 2022 Password Expires: Jan 22, 2023 Password Inactive: Never Account Expires: Never
