## Overview
DUMA is an IBM Aspera deployment at the LCSB-University of Luxembourg. DUMA supports end-to-end encrypted data transfer and can handle high data volumes e.g. several tera bytes.

## Obtaining a DUMA access link
## Obtaining a AsperaWEB access link
You need an **access link** to use DUMA. An access link is a temporary, password-protected space, much like a drop box, on LCSB's DUMA server. In order to obtain an access link, you should contact your research collaborator at the LCSB-University of Luxembourg. Once created, you will receive your **access link** and associated **password** (link) by e-mail.

**IMPORTANT NOTE: Whenever the LCSB shares a password for a DUMA endpoint (collaborator), the password be reachable via a link, which will expire. Therefore you should make a record of your password once you view it.**

An access link can be reached via standard web browsers. Data can be transferred to/from an access link in two ways:
* Through the web browser by visiting the link, which is our recommended way of data transfer, described in this [section of the guide](#DUMA_WEB)
* Through the use of a command line tool. If your data sits in an environment, where you can not launch a web browser, then you may use use a command line client tool to reach an access link. This process is described in this [section of this guide](#DUMA_CLI).

The use of DUMA is mediated by LCSB's data stewards. If you require assistance in using DUMA, you should send an email to [LCSB admin team](mailto:lcsb-sysadmins@uni.lu).

## Accessing DUMA via Command-Line Tool
In the following steps we describe instructions on how to use DUMA web interface.
1. **Install the aspera command line client.** The _ascp_ tool, which can be found [here](https://downloads.asperasoft.com/en/downloads/62) as instructed.
1. **Obtain tokens.** You will need **tokens** while using _ascp_. You will need a **download token** for download and a separate **upload token** for upload. Your tokens can be viewed by clicking the **Help** icon on your access link (see below).<br/>
![Alt](duma_help_link.png "Title") <br/><br/><br/>
![Alt](duma_cli_tokens.png "Title")
1. **Obtain encryption passphrase.** You should receive corresponding passphrase from repository administrator.
1. **Obtain SSH key.** You will also need an **SSH private key** to authenticate. This is the Aspera key that comes with the Aspera Connect installation named `asperaweb_id_dsa.openssh`. Below are locations where the ssh_key can be found:
* On MAC
* Local installation of Aspera connect:
* `/Users/username/Applications/Aspera Connect.app/Contents/Resources/asperaweb_id_dsa.openssh`
* System wide installation of Connect:
* `/Applications/Aspera Connect.app/Contents/Resources/asperaweb_id_dsa.openssh`
* On WINDOWS
* Local installation of Aspera connect:
* `C:\\Users\username\AppData\Local\Programs\Aspera\Aspera Connect\etc\asperaweb_id_dsa.openssh`
* System wide installation of Connect:
* `C:\\Program Files (x86)\Aspera\Aspera Connect\etc\asperaweb_id_dsa.openssh`
* On LINUX
* Local installation of Aspera connect:
* `/home/username/.aspera/connect/etc/asperaweb_id_dsa.openssh`
* System wide installation of Connect:
* `/opt/aspera/etc/asperaweb_id_dsa.openssh`
1. **Set necessary environment variables**. `KEY` and `TOKEN` environment variables should be set as follows. If you do not have any of the tokens use `None` as the value.
* `KEY=<path to the ssh key>`
* `DTOKEN=<<<<YOUR DOWNLOAD TOKEN>>>>>>`
* `UTOKEN=<<<<YOUR UPLOAD TOKEN>>>>>>`
* `export ASPERA_SCP_FILEPASS=<<<<<YOUR ENCRYPTION PASSPHRASE>>>>>`

## Accessing AsperaWEB via Command-Line Tool
1. **Run the relevant _ascp_ commands**.
Go to the help section of your access link
* Upload:
* To upload all *png* files to the root of the share:
* `ascp -d -i $KEY -P 33001 --file-crypt=encrypt -W $UTOKEN *.png app_duma_public_read@aspera.lcsb.uni.lu:/`
* To upload *document.txt* to a subfolder:
* `ascp -d -i $KEY -P 33001 --file-crypt=encrypt -W $UTOKEN document.txt app_duma_public_read@aspera.lcsb.uni.lu:/subfolder`
* Download:
* To download *subfolder* and all it's content to the current directory:
* `ascp -d -i $KEY -P 33001 --file-crypt=decrypt -W $DTOKEN app_duma_public_read@aspera.lcsb.uni.lu:subfolder`
