User accounts

Getting access

For access to Aether, please send an e-mail to lamos_it+aether@groups.uni-bremen.de, in which you state the username and, if applicable, the user ID (UID) which you have on the IUP-systems.

Mailing-list

All users of Aether are automatically subscribed to a moderated mailing-list aether-announce where we will distribute announcements regarding the operation of Aether. On the same webpage, you can unsubscribe or change the subscription options.

Changing the user’s password

Each user has two passwords for the Aether cluster: one Linux system password (for SSH- and JupyterHub-logins) and one Samba password (for accessing the Aether storage from within IUP-network via the SMB protocol, i.e., from Windows PCs).

Warning

The Linux and Samba passwords are separate entities and can, potentially, be different from each other!

In order to minimize the potential confusion coming from having two different passwords, we have created a script changepasswd. This script will first ask you to change your Linux password, and then it will ask you to change your Samba password.

[hilboll@login1 ~]$ changepasswd

***********************************************************
            Your LINUX PASSWORD will be changed

***********************************************************

DONE!

If you want to change only one of the two passwords, you have to specify which one, like this: changepasswd linux or changepasswd samba.
