This page informs about our group network drive proni, how to connect to it and how to control file access on it.
with your ZIH-account password. If you're asked, you should agree that the network drive is automatically mapped at startup. If everything worked, you should have a new drive with the drive letter you chose which contains all the shared files. If it didn't work, it might be, because we haven't added you to the proni user group, yet. Check with someone who is responsible for that.
You can also setup SSH putlic key authentication so that you don't have to type in your password every time you reconnect. Information about this can be found by searching the internet, or, for example, here, or here.
The connection to proni will be cut automatically after some time of inactivity.
shared reading: The owner of the files allows everyone in the group to read the files, but only the owner can change, move, delete and add files.
shared editing: The owner of the files allows everyone in the group to read and edit the files he created, but only the owner can delete or move them. All group members can add new files which they can also delete.
shared ownership: All members of the group can equally read, edit, create and delete files.
When you create a new directory in proni the default access rights are different, when you do this in Linux or Windows. In the following I will explain the defaults and how they can be overwritten in the two operating systems.
The default access rights for new files in Windows are shared ownership, i.e., all group members can do everything with them. For example, when you copy your raw data to proni in the Windows explorer, everyone in the group can edit and delete these files.
Note that the changes you are making only apply to the selected files unless you tick the box which says something like "set rights recursively" when you selected a directory. When this is ticked, all the content of the directory is set to the corresponding rights.
It is ok to set the rights for directories listed above to files, but setting the listed rights for files on directories can make files that you add later unreadable by group members, i.e., this could break sharing.
You can only change rights of files or directories that you own, i.e., that you created. If you try to change access rights to files that you don't own, a 'permission denied' error will be raised, even if you had write access to the file through the group.
The default access rights for new files in Linux are extended shared reading. The extended part comes from Linux allowing all users, even those outside the group, to read the files. Notice, however, that this is irrelevant in proni, because no-one except for us has access to the proni root folder in the first place.
The ZIH maintains some information about their file system services, but currently only in German.
