Passwords

How can I change my password?

This depends on which password you want to change. At UCSD, there are three password databases and SCCN has its own user database.

SCCN password

SCCN runs its own user database separate from UCSD's databases. To change your SCCN password, you must log into sccn.ucsd.edu ("ssh sccn.ucsd.edu") and run the "smbpasswd" command through a terminal.

A password change interaction looks like the following:

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

Open the Terminal app (type "term" in your search box to locate it quickly). Windows users will have to install an SSH client, such as PuTTY.

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

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.

Pay close attention to the result. If the password change was unsuccessful, run the smbpasswd command again. This is an error you may receive if you mistype your Old SMB password:

Could not connect to machine 127.0.0.1: NT_STATUS_LOGON_FAILURE 

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

$ exit
