Changing user passwords on cluster
There are two ways of changing your password on the cluster: using the Finder, or the unix 'passwd' command. This document describes both methods in detail:
Changing your password using FinderChanging your password using Finder
Changing your password using 'passwd' command
Assuming that you are working from a Mac, running OS X, the following steps will allow you to change your password on the cluster (or any other Mac OS X machine you have access to). If you are working from any other type of machine/operating system, you will need to change your password using the passwd command.Changing your password using 'passwd' command
You can use this method to change your password on the cluster from any type of machine/operating system, providing you have an application which allows you to run ssh (Secure Shell) to connect to the remote server. On a Windows machine, you will need to get an ssh application (I believe there are some free downloads available from www.versiontracker.com, but I am not sure. You will need to look elsewhere for help with ssh on Windows.). On any type of unix or linux machine, you should be able to use ssh via an xterm. On a Mac OS X, ssh can be used from the Terminal Application:

Step 1. In the Finder window, navigate to the Terminal application. It can be found in Applications -> Utilities -> Terminal.
Step 2. When you open the Terminal application. you will see a welcome window, similar to this. Other unix/linux users should see a similar xterm window.
All of the commands in the following steps below should be typed at the prompt. Hit the Return key after every command.
Step 3. Now that the Terminal is open, you will have to connect to the cluster machine. The only way to connect via Terminal, is to use the ssh command. All Mac OS X machines have ssh installed. If you are unsure you have ssh, you can check by typing:
which ssh
and the response should be a full path to where ssh is installed. On an OS X machine, it will be: /usr/bin/ssh. If you get ssh: Command not found. then you either do not have ssh installed, or it is not on your path.
To connect to the cluster type:
ssh username@fmri00-miles.hosted.ats.ucla.edu
where 'username' is the username that was setup for you on the cluster. The remote machine will then ask you for your password:
username@fmri00-miles.hosted.ats.ucla.edu's password:
Type your current password and you will be logged on and welcomed to cluster:
Welcome to Darwin!
[fmri00-miles:~] username%
Step 4. Finally, to change the password type:
passwd
and enter your old (current, the one you used to log in) password:
Changing password for username.
Old password:
You will then be prompted to enter and retype the new password:
Changing password for username.
Old password:
New password:
Retype new password:
And, that's it! You have a new password...
