We are operating the cloud storage service ownCloud at https://owncloud.cesnet.cz. This application is best suited for smaller amount of files that you want to access via web interface. You can sync your files between PC or mobile devices or share them with your colleagues. You can also use ownCloud to share contacts and calendars.

To use ownCloud, you have to be an employee or a student of an academic organization. For technical reasons, you have to have an account in eduID.cz. ¹⁾. You have to comply with (terms of the service) as well. There is no need to register anywhere, your account will be created automatically when you log in for the first time.

How to log in:

1. At the website https://owncloud.cesnet.cz click on “Sign In to ownCloud” button.

2. Now you shall be redirected to the selection list of an identity providers (e.g. CESNET, CTU, MUNI…)

3. Please select your identity provider and then log in.

4. After logging in you will be redirected to the websites, where you will be asked to express your approval to deliver several attributes required for OwnCloud service. Those attributes are used to verify that you are authorized to use OwnCloud service.

5. You will be logged in to ownCloud after clicking on the Authorize button.

After first logging in, you will be notified via email.

CESNET e-infrastructure services use a unified user management system (if technically possible) for managing user access. In case you haven't used Data Storage services nor MetaCentrum facilities so far, you will be asked to register your identity into the CESNET e-infrastructure. You may be asked to do so if you accessed those services using a different identity than you trying to access ownCloud. Should you have more identities in academic institutions, you can (in fact, you are strongly recommended to) connect them into a single one (so that the e-infrastructure recognises that, e.g. jan.prochazka@cesnet.cz is the same user like jan.prochazka@cvut.cz).

How to sign into the e-infrastructure and to register to ownCloud:

1. Visit https://owncloud.cesnet.cz or https://filesender.cesnet.cz in your web browser and click on Sign In to ownCloud button or Login button in case of FileSender service. Select your institution from the list and log in using your credentials as usual.

2. On the following page, click Register in the “New user” section.

If you are familiar with identity management in the e-infrastructure, you can connect your account with another existing identity (identity which you used to connect for instance to the MetaCentrum). This can be done later, so if you have no idea what this paragraph is about, just continue to the following item, no harm will be done. If you wish to consolidate your identities, please click on Link a new account in the section “Already registered?”. Then you will be redirected to the page where you can select the other identity. Then you sign in again and then the system will connect both identities into one.

3. After choosing registration as a New user, the procedure will be as follows. The app will search for registered users (existing accounts). If there is any user with the same attributes as yourself, the app will offer you joining both accounts into one. List of identities that have been recognised as possibly yours will be shown in the dialog box. If this is correct, you are advised to join the identities.
In case none of those identities belongs to you, please click on the It's not me button.
If the system found your identities, but it indicates that they cannot be merged automatically, contact the user support as you are advised by the system.

4. In the following page, a short form with prefilled attributes (name, email, …) will appear. In the end of the form please click on the Request an account in einfrastructure button.

5. In the next page, your registration will be confirmed. You are now member of einfra. Simultaneously you will receive a confirmation email. Your registration will be immediately approved, which is stated by another email confirmation. Now you can continue by clicking on the Continue button. Now you will be redirected to the required service.

6. Now you are requested to agree with releasing attributes that are necessary to use the ownCloud/FileSender service.

4. After you click on OK desktop client stops to sync Shared folder. That action does not have influence on the data on server. On the server (via web interface) you have all shared data still available and you can download it.

Desktop client is defaultly set to check every 30 seconds for the changes in the files uploaded in the ownCloud server. Sometimes it can be desirable to set up sync frequency higher or lower. Sync frequency can be set in the ownCloud configuration file, which can be found in:

• Linux:

$HOME/.local/share/data/ownCloud/owncloud.cfg

• Windows:

%LOCALAPPDATA%\ownCloud\owncloud.cfg

• Mac:

$HOME/Library/Application Support/ownCloud

You can add new row remotePollInterval=30000 into the section [ownCloud], where the numeral value is desired sync frequency in milliseconds.

In ownCloud, you can share any file with any other registered ownCloud user. To share your files with an user you have to know the email of the user. Sharing setup is shown on the following figures.

Space occupied by the shared files is counted into the occupied space of the user who created this files.

However this guideline doesn't respect our modifi cations.

We do not recommend you to use Internet Explorer 11. JavaScript required for ownCloud web interface is not working properly.

Internet Explorer 6 is using vulnerable SSLv3. By the reason of keeping the security, our servers require TLSv1.0 and higher. Thus it is necessary to use web browser, which doesn't use SSL, but TLS.

Problem description: I have logged in via different identity provider compare to my first logging in. Now I don't see my files. Why?

Solution: We suppose, that you have used different identity for your current logging in than in the past. In case you have used more identities of different organizations, for each of your identity (past and current one) was created new ownCloud account. For this kind of issue is necessary to join (consolidate) both your identities into one. So afterward no matter which identity you will use you shall see still same files. To consolidate your identities please contact us at support(at)cesnet.cz

Problem description: There appear authorization request after every system startup, which keeps opening my web browser.

Solution: That issue is related to storing of the ownCloud access token. If ownCloud client starts prior to the subsystems containing stored access token, ownCloud client requires to re-authorize the access.

In case of Linux system it is necessary to use Keyring service provided form your environment (e.g. Keyring, MATE Keyring and so on). Although you use Keyring service, it is possible that ownCloud client starts prior to the subsystems. In case of Windows it is very similar bug. Re-authorization problem will be fixed with new version of ownCloud client.

Problem description I was uploading file via web interface. After it finished I cannot see my file. Why?

Solution: Uploading of one file via web interface is possible maximally for 4 hours. If you will upload your file via ownCloud Desktop client this restriction is invalid. So to upload your files, please use Desktop Client, see the section Desktop client

1) Problem description My client cannot connect to the ownCloud server even I am using correct password.

1) Solution: ownCloud version 10 and login procedures deployed in June 2018 need desktop client version at least 2.4.0. Desktop client usually check automatically for new versions. So the Desktop client can be updated immediately after the new version release.
We recommend you to use for update: ownCloud webpage, where are available official Dekstop clients for various platform i.e. Windows, OS X and Linux. For Linux is also useful to install repository. Due to this repository you can install new versions in common way (apt-get update, yum update …).

Problem description I am trying to share file with my colleague and I cannot find his/her username (email address).

Solution: Due to security reasons is unsuspecting prohibited. To share given file with any user, this user must be registered in the service https://owncloud.cesnet.cz/.

The user name is not necessarily email address, which you are used to use. Your colleague can find the username in page “Personal” in ownCloud web interface (Please log in to the web interface → In right up corner click on your name → Personal).

Problem description I have synced executable file from one computer to the second computer. However the file is not executable on the second computer.
