How to connect via point-and-click Graphical User Interface (GUI) on Linux host
If you want a full point and click interface to control programs with your mouse, you can use a VNC client.
Ronin provides a pre-configured method available through Ronin-link. When you click “Connect to Machine” you will be given the option to connect via “Desktop”, the first time you click that it will install the NICE DCV server and launch you a desktop.
For native instructions on how to set this up see the AWS documentation:

How to copy data to and from RDS
You can use the usual methods to copy to and from your RDS drive as you would from any off-network location, i.e. see for details Research Data Store
Or you can mount your RDS drive on your image using a tool like sshfs with these commands:
sudo apt install sshfs
mkdir /home/ubuntu/myRDS
sshfs <unikey>@research-data-ext.sydney.edu.au:/rds/PRJ-<yourproject> /home/ubuntu/myRDS
Done! Now you can copy back and forth between RDS and your RONIN machine seamlessly.
If you need to un-mount your drive, use:
sudo umount /home/ubuntu/myRDS
Note: there is a cost (~$0.15/GB) for copying data TO your RDS drive (data egress). Copying data from your RDS is free (data ingress).
Can I use an S3 bucket for storage.
Yes! If you want to keep your data in the AWS cloud, you can add and use S3 storage as required, for details see:
https://blog.ronin.cloud/object-storage/
If you want to connect to an external S3 bucket you may have to add the “--no-sign-request“ flag. For example:
aws s3 ls s3://sra-pub-sars-cov2/README.txt --no-sign-request
Adding additional users to Auto Scale Clusters
Sometimes you may want to add a new user to the machine that is not part of the project, but may need to connect to the box. Generally this is not recommended. Nevertheless you can run a script like this:
#!/bin/bash
SRC=$1
DEST=$2
SRC_GROUPS=$(id -Gn ${SRC} | sed "s/ /,/g" | sed -r 's/\<'sudo'\>\b,?//g' | sed -r 's/\<'${SRC}'\>\b,?//g')
SRC_SHELL=$(awk -F : -v name=${SRC} '(name == $1) { print $7 }' /etc/passwd)
sudo useradd --groups ${SRC_GROUPS} --shell ${SRC_SHELL} --create-home ${DEST}
sudo passwd ${DEST}
And create a new user with “clone_user.sh ubuntu newusername”
You then will need to call sbatch (and similar) from its path, e.g. /opt/slurm/bin/sbatch
Again, not recommended for Ronin, but you may find a use case where you need to do this. Note, there is additional configuration required to allow this user to login via ssh.
