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.
ssh -p <your capsule's port> email@example.com
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.

If you will need more than one session to complete your research, save your interim data.
Expand title Save data to Secure Volume
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:
releaseresults add /home/demouser/demo/r/Rplots.pdf
Repeat using this command if you have other files to add.
Between sessions, stop the capsule via the HTRC using the web browser on your personal desktop. The next time you log in, you can restart the same capsule and continue your work.
When you are finished with your research, request to export your non-consumptive data.

- When you no longer need it, delete your capsule via the HTRC.
