Nextcloud is a tool, similar to Dropbox, that allows sharing files easily through the web. It is the most convenient way to give access to your file on the storage to colleagues who live abroad.

Nextcloud is accessed through the following URL: You will need to use your CISM login and password. The default storage space in Nextcloud is very small ; it is primarily dedicated to sharing files that are on the storage. To do so, you will need to configure your Nextcloud profile and enter your CISM login and password.

Once connected, click on the triangle near your login, and choose ‘Personal’. Then click on ‘External Storage’ and give the name you want it to have in your Nextcloud space, choose SFTP as protocol, and ‘Username and password’ as Authentication. Then enter, you home directory (which you can discover by typing pwd when you are connected to the storage server), your CISM login and password.


Once done, you will have a new folder in your Nextcloud space that lists the contents of your space on the storage servers.


From there you can use Nextcloud’s sharing facilities to exchange files with other colleagues.


We transitioned from ownCloud to NextCloud but we did not migrate the data. If you have configured ownCloud in the past, you can still access it through the usual URL. Please migrate your data and configurations to NextCloud as the latter infrastructure is more powerful.

SSH gateways

The SSH gateways allow you to access resources that are available only inside the university network eventhough you are home or abroad. With the gateway, you can connect to the CECI clusters, to Manneback, to the interactive machines, or to the storage machines that are normally only accessible when you are connected to the university network (wired or wifi ).

There are two gateways that you can use, depending on the account you have.

  • CISM account: use gwcism
  • CÉCI account: use gwceci

To know how to configure the gateway, please refer to the CÉCI documentation:

The information you need is the following:

  • For gwcism :
    • Gateway address:
    • Port: 22
    • Username: <Your CISM username>
    • Password: <The password of your CISM account>
  • For gwceci :
    • Gateway address:
    • Port: 22
    • Username: <Your CÉCI username>
    • Private ssh key: <Your CÉCI key file (id_rsa.ceci)>
    • Passphrase: <The passphrase corresponding to your CÉCI SSH key>

To renew your account from outside UCLouvain, you can simply connect to with X forwarding and run firefox with the --no-remote option. Go to the website as usual, enter your email address and then copy/paste the URL you then receive by email in the remote firefox window and fill in the web form from there.


You do not need to be abroad or home to use and test the connectio to the gateway. Make sure it all works through the gatewat when you are in your office before attempting to connect from home.


Also make your connection to the gateway itself is functionnal before using it through a proxy command.


This directory was created for you when you registered. It is given as a simple means to organize a replication-based backup strategy. This strategy consists in duplicating all your data on distinct servers in distinct rooms so as to minimize losses due to hazard.

Every file that you copy in this directory is synchronized every hour on another server in another room. Note that therefore, the space you use in that directory is charged twice!

Note that because it is used twice on distinct servers ; data in ALSOreplicus are copied every hour onto another server to serve as a simple backup procedure.
