Once you have your capsule running, you may find it useful to open this guide in an internet browser in your capsule so you can copy and paste commands. The short link for this page is: https://wiki.htrc.illinois.edu/x/TQFRAQ.
Install a VNC client on your computer to enable the communication between your computer and the capsule you will remote access into. You can choose any VNC client you prefer. We use VNC View for Google Chrome in the screenshots below.
From the HTRC, create a capsule by clicking on Capsule → Create Capsule on the top menu. You will be asked to provide information about the capsule you would like to create.
Start the capsule you created by clicking the Start Capsule button on the Show Capsules page.
Interact with the capsule via the VNC client.
Alternatively, you can SSH into your capsule when it is in maintenance mode only.
Key information for accessing your capsule is located on the Capsule Status page.
On a Linux terminal, enter the following command inserting your capsule's port number found on the Capsule Status page. Then enter the password dcuser when prompted.
Note that if you want to interact with the Ubuntu desktop of your capsule, or if you want to use your capsule in secure mode, you will need to use a VNC client as described above.
Switch between maintenance and secure mode.
Fetch volume OCR content using the HTRC Data API.
Run experiments. Follow the Use Case guides for examples.
Save your interim data between research sessions.
Save data to the Secure Volume
Make sure your capsule is in secure mode (see directions above if needed).
Open a terminal window in the capsule and navigate to the secure volume by typing:
Suppose the file you'd like to release is at /home/demouser/demo/r/Rplots.pdf
You can prepare the result data for release by adding it, which is done by typing the command:
Repeat using this command if you have other files to add.
Stop the capsule. The next time you log in, you can restart the same capsule and continue your work.
Request to export your non-consumptive data.
