Computing Accounts

Please register for scientific computing accounts via the links below. You will first need to be signed in via your Warwick IT services account.

• SCRTP account. Required immediately! Use the Department of your primary supervisor, or their research group if it has a specific entry, as your affiliation.
• SCRTP HPC account: Use the Department of your primary supervisor as your affiliation. Not immediately required, only register when you need high performance computing access.

Laptops

Installation of required packages

Your HetSys-provided laptop is preinstalled with Ubuntu 20.04, with 100 GB of free space left on the drive in case you want to install Windows yourself. The script below has already been run for you to install a number of useful packages.

Docking Stations

The HetSys desks in the workspace in D215 have been equipped with docking stations that are compatible with the HetSys-provided laptops. Upon connecting the USB cable from the docking station to the laptop, you should find it automatically connects to ethernet and the wireless keyboard and mouse.

However, enabling the display takes a little more work. Please note: until you have had a chance to do this, it is fine to move the HDMI cable from the docking station to directly connecting to the laptop.

and run the script below (noting caveats in the comments):

Printing

Once the driver is installed according to the instructions in the leaflet, execute the following commands:

sudo usermod -a -G lpadmin \$USER   # add current user to lpadmin groupsudo apt-get install samba         # Install SMB version 2sudo apt-get install smbclient     # Install SMB client package

Now edit the smb.conf config file, e.g. with vi (although you can use any editor)

sudo vi /etc/samba/smb.conf

Find the [global] section and add the following line at the end:

min protocol = SMB2

Finally, restart the Samba server with

sudo systemctl restart smbd.service

Here are some notes from Chris Woodgate (Cohort 1) on backing up your laptop.
My policy is to keep everything important and work related in one folder off my home directory in my laptop. So I have a folder ~/PhD where I keep everything important on my laptop. Make this folder, and remember to keep everything you want to back up in there!
Then, to back up:

First, ssh into your SCRTP homespace:

ssh phrxyz@godzilla.csc.warwick.ac.uk

Replace phrxyz with your SCRTP username. You will be prompted for your SCRTP password. I am lazy so I have a list of remote machines I commonly use in a file called config in my ~/.ssh directory (Google it!). That way I can just run ssh godzilla rather than typing out the whole address. godzilla is just a login machine for the SCRTP system.

Then, navigate to your home directory:

cd

Create a folder to which you will back up. I call mine laptop_backup. Keep it in your SCRTP home directory if you want to keep your life simple!

mkdir ~/laptop_backup

Then disconnect from Godzilla:

exit

Now, in your home directory, you are finally ready to backup the contents of the PhD folder. Run the command:

rsync -rv --delete PhD/ phrxyz@godzilla.csc.warwick.ac.uk:~/laptop_backup

-r means recursive (it digs down into folders). -v means verbose (you can see the progress rsync is making). --delete makes rsync delete files which are present on the SCRTP folder which are not present in your work folder (use with care: don't get the two folders the wrong way around!). This command will typically be slow the first time you use it because it has to copy everything, but quicker later on as it only copies files which have changed.

There will be a way to set this to happen automatically but I haven't bothered with that yet; I just try to remember to do it when I finish my work for the day. The SCRTP system is backed up by people who know what they're doing, so once your files are on that system they should be very safe.
