Resetting SSH rootid passphrase

Follow these steps to reset the SSH rootid passphrase when it is unknown:

  1. Log in to the NVE using SSH as an admin user.
  2. Switch to the root user by entering the command sudo su.
  3. Delete the rootid_key and rootid_passphrase_encrypted files from the /usr/local/networker folder.
  4. Generate the rootid and the adminkey without passphrase.
  5. Apply the latest NVEUpgrade.

Details for steps 3 and 4 are as follows:

# Change directory to /usr/local/networker
cd /usr/local/networker

# Delete rootid_key and rootid_passphrase_encrypted files
rm -rf rootid_key rootid_passphrase_encrypted

# Generate rootid without passphrase
ssh-keygen -q -t ecdsa -b 521 -N "" -C "root@`hostname`" -f /root/.ssh/rootid

# Generate adminkey without passphrase
ssh-keygen -q -t ecdsa -b 521 -N "" -C "admin@`hostname`" -f /home/admin/.ssh/admin_key
NOTE: If prompted to overwrite, click Yes.

Additional Information

WARNING: The process outlined in this article disables root passphrase protection. To reinforce security enhancements, upgrade to the next 19.12+ NetWorker release. 19.12+ versions include features designed to re-enable encryption of the rootid using a passphrase, strengthening security measures. The NVE upgrade process re-enables passphrase protection. There is currently no method outside of the NVE upgrade workflow to re-enable passphrase protection.
