Computer Account

SCCN Account

SCCN has separate computer accounts from the UC San Diego Active Directory accounts. Use this account for logging onto the networked Linux workstations and accessing the lab file shares.

How can I change my password?

To change your SCCN password, you must log into ("ssh") and run the "smbpasswd" command through a terminal. In some cases, a VPN connection may be required since this system is only accessible from the UC San Diego network.

Open a terminal.

Windows: Press the Windows key and type "power" to locate and run PowerShell.
Mac: Press Command-Space and type "term" to locate and run Terminal.
Linux: Locate Terminal from the application menus or press the Windows key and type "term" to locate and run Terminal.

Log in with your SCCN username and password at the prompts.

Next, run the smbpasswd command to change your password. Note that the password will not appear as you type it.

A password change interaction looks like the following:

$ ssh
  Last login: Tue Dec  1 12:49:08 2015
     Swartz Center for Computational Neuroscience         
  $ smbpasswd
  Old SMB password:
  New SMB password:
  Retype new SMB password:
  Password changed for user x

If prompted to accept host keys, you must choose "yes"/"accept".

Pay close attention to the result. If the password change was unsuccessful, run the smbpasswd command again.

If you receive the following error, you may be trying to run the smbpasswd command on your local workstation and not on the server.

  Could not connect to machine NT_STATUS_LOGON_FAILURE 

After successfully changing your password, exit the terminal to log off.

$ exit
