To change your password, long into a cluster machine using ssh:
ssh -Y username@miles.shadlen.org
Now run the command:
passwd
It will ask you for you password, this is your current password. After entering your current password, it will ask you for your new password. If it likes your new password, it will tell you to re-type it. None of the passwords will show up on the command line, so your terminal will end up looking something like this:
maria@miles:~$ passwd Enter login(LDAP) password: New UNIX password: Retype new UNIX password: LDAP password information changed for maria passwd: password updated successfully
That's it!
