NOTE that you will have to change the first occurrence of "almaXX" with your ssh account (e.g. "jbrand"). The script silently assumes that those two account names are the same which is true for everyone except for this tutorial.

Enter the appropriate passwords

vncviewer --help

to check).

Red Hat:

sudo yum install tigervnc  

sudo apt-get install xtightvncviewer

MacOS: e.g. Chicken of the VNC.

Steps to access the processing cluster

1) Remote user: ssh into ESO

ssh <username>@ssh.eso.org

2) Remote and local users: ssh into the cluster gateway arcp1

ssh <username almaXX>@arcp1.hq.eso.org

3) Start your vncserver on the cluster using the geometry of your screen, e.g.:

getvnc.sh -geometry 2000x1000

4) You will be asked to provide a new password, enter the password of the almaXX ssh account.

5) On your laptop/home machine, open two terminal windows and copy the the first connection string written out by the script into the first one. Enter the appropriate passwords

6) Linux users: use the second connection string to connect to your VNC server

7) MacOS users: start Chicken of the VNC and connect to "localhost".

You should see a virtual terminal on the processing cluster.

8) At the end of the day, remove the vnc server from the cluster with

getvnc.sh -k

Working on the cluster

Get an interactive shell one the freest cluster node (the gateway node should not be used for processing), type
