There are **two different methods** to connect to the mass storage.

If you want to access data stored on the mass storage via your computer's file browser, mainly to work on small files or to transfer files from your computer to the mass storage, you need to connect from your computer's file browser, using the SAMBA protocol.

For both methods, you need to be on the Uliège of CHU network (wired or WIFI). To access your data from outside of these networks, you must use a VPN connection. Instructions to connect to the university VPN can be found [here](vpn-connection).

For your **first** connection to the mass storage, you **must** log in from your computer's file browser via the SMB/SAMBA/CIFS protocol (see above).

Indeed, this first connection will trigger the creation of different links to shared project and resource folders in the user’s home directory. If the first connection is not done trough SMB/SAMBA/CIFS but by ssh, the user’s home folder will be created on a different disk and won’t contain the required links. In this case, system administrators will need to be contacted to manually move the user’s home folder to the mass storage and to create the links.

|
|
|
|
|
|
|
|
Depending on what you want to do, you will establish a ssh connection either directly to the mass storage or to the cluster. In both cases, you will end up in your home directory and will have access to all your data.

|
### If you want to manage your files (move/copy/etc) or if you want to download/upload large files from/to another server or computer
|
|
|
|
|
|
|
|
You can connect directly to the mass storage using the following procedure:
|
|
|
|
|
|
|
|
- In the terminal of your machine, enter
|
|
|
|
|
|
|
|
```
|
|
|
|
ssh u123456@cluster.calc.priv
|
|
|
|
ssh u123456@massstorage.giga.priv
|
|
|
|
```
|
|
|
|
|
|
|
|
- When prompted, enter you password
|
|
|
|
|
|
|
|
- You are now in your home directory on the mass storage.
|
|
|
|
|
|
|
|
Of note, you can also use the mass storage address (u123456@massstorage.giga.priv) to transfer larges files from your computer or from another server to the mass storage with [scp](https://technique.arscenic.org/transfert-de-donnees-entre/article/scp-transfert-de-fichier-a-travers) or [rsync](https://linuxize.com/post/how-to-transfer-files-with-rsync-over-ssh/).

|
WARNING: Don't perform any calculation or analysis on your data while connected directly to the mass storage. To analyse data, you must connect to the cluster as explained below.
|
|
|
|
|
|
|
|
### If you want to perform analyses or calculations on your data
|
|
|
|
|
|
|
|
You must connect to the cluster using the following procedure:
|
|

|
|
|
|
- In the terminal of your machine, enter
|
|
|
|
|
|
|
|
```
|

|
|
|
|
|
|
- When prompted, enter you password
|
|
|
|
|
|
|
