How to Reset Linux Operating System (OS) User Passwords on the NextSeq 1000/2000

Background

The Linux Operating System (OS) on the NextSeq 1000/2000 has three accounts:

• ilmnadmin (Administrator)

• ilmnuser (User)

The ilmnadmin Administrator account is intended only for applying system updates, like updating the NextSeq 1000/2000 Control Software, or for use by IT staff to mount a persistent network drive. Perform all other functions, including sequencing, from the ilmnuser user account.

The login credentials are specific to each account. If there are too many failed login attempts with the incorrect password, the account locks. The timeout for a locked user account is 10 minutes.

If the password for ilmnuser is manually changed by the ilmnadmin Administrator account, the lock-out timer is NOT be removed.

Resolution Actions

To reset the ilmnuser password from the ilmnadmin account:

1. Log into the Linux OS as ilmnadmin.

2. Select the Activities menu in the top-left corner, then input terminal to open the Terminal application.

3. Enter sudo passwd ilmnuser and press Enter.

4. Enter the ilmnadmin password when prompted.

5. Enter a new ilmnuser password at the prompt, then press Enter.

6. Retype the new ilmnuser password at the prompt, then press Enter to confirm the new password.
