Both accounts have the same default password: LCLS2014    Please, change the one as soon as you start the image and log into the system! Protecting your system is solely your own responsibility. The passwords can be changed by logging as pcds and then switching to the superuser mode using one of the following commands:

 

Code Block
% sudiosudo -i
% su

You should use the superuser account to manage your system (add/remove accounts, change passwords, configure the network, mount dists, etc.). The second account is used to install the LCLS releases. We do NOT recommend using that pcds account for your software development. The account has a special configuration for importing/updating releases. This document may later be extended to explain how one could upgrade to the latest analysis release using this account w/o re-installing the VM from scratch. We highly recommend that you created your own user accounts for your analysis activities. Just make sure you set up the analysis environment for that accounts as explained in the Analysis SetupEnvironment Details document.

 Which software is installed

Basically, we've tried to replicate the usual analysis environment, including the names of releases, a location of the release, the environment initialization commands (sit_setup), etc. And each VM image comes with at least one version of the full analysis release:

Code Block
% ls -al /reg/g/psdm/sw/releases/
total 12
drwxr-xr-x.   3 pcds pcds 4096 Aug  5 13:44 .
drwxrwxr-x.   5 pcds pcds 4096 Apr  4 18:04 ..
drwxr-xr-x. 101 pcds pcds 4096 Aug  5 13:38 ana-0.13.0
lrwxrwxrwx.   1 pcds pcds   10 Aug  5 13:40 ana-current -> ana-0.13.0

We also put a few tutorials for using the interactive psana (explained at psana - Python Script Tutorial) into the image:

Code Block
% ls -al /reg/g/psdm/tutorials/

drwxrwsr-x. 6 pcds pcds 4096 Apr  4 17:55 .

There are some important notes regarding what's not available on the VM:

  • you won't be able to see your NFS home directory even if you will add your own account to the system using your sudo privilege
  • all accounts found on the machine have nothing to do with LCLS accounts
  • you won't be able to see any data directories (you can mount the ones using sshfs as explained later in this document)
