What does Filesender service provide?

FileSender is a single-purpose web service used for quick and easy sending large files up to hundreds of recipients.

This service is primarily intended for sending data that has scientific or/and educational character. Organizations from eduID.cz federation, universities, libraries, scientific institutions and students are the target group for this FileSender service . This is simple, single-purpose application. It can upload files of authenticated users over eduID.cz federation and also allow sending time-limited invitations for uploading files for people who don't have account in eduID.cz federation.

FileSender's user can define a list of recipients email addresses after uploading the file into the data storage. Selected recipients will receive the message with the link to desired file. Downloading of desired file located in data storage is protected by the knowledge of correct URL. Via web interface is possible to see the file list, which you can remove or re-share. Each file stored in data storage using FileSender service has an expiration period. This expiration period can be set up by the user. In case of expiration period exceeding the file is automatically removed. User, who has uploaded the file, is notified via email about each download of that file.

The Filesender service is for sending files only. Files have a default expiration of 10 days, which can be moved to a maximum of 30 days.. The files are then deleted beyond recovery. If you need to save data, please choose another service, for example ownCloud.

First logging into the CESNET e-infrastructure

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).

There are several reasons for this complexity. We are preparing new features in the system. You will be able to connect any social identity to your academia identity. That social identity (Google, Facebook) can be then used to sign in to ownCloud, for instance. Social identities will appear in the list of possible institutions during login procedures when this functionality is turned on. We will only require that you to log in using your academic identity, from time to time, to show you still belong to the community. That is necessary because of the terms and limitations of projects funding our services like ownCloud. Such kind of verification would not be necessary for each and every service, it will be shared. Note that in the ideal case, a single person should have only one account in e-infrastructure and all related identities from external sources should be connected to that main identity.

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.

If you have been redirected directly to the ownCloud dashboard (you can see your data) or to FileSender service it is not necessary to follow this tutorial. You can start to use ownCloud/FileSender service right away.

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

If you have already used ownCloud or FileSender earlier and you are logging in for the first time since the upgrade in June 2018, don't worry about the “New User” stuff and use it. It is not creating a new user in ownCloud, it is just an e-infrastructure registration. Use the same account from the same institution you used before the upgrade. Additional identitites can be added at any later point of time. Currently, ownCloud only supports logging in using the same institution you originally used to create the account.

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.

7. After clicking on Yes continue button, you will be redirected to ownCloud/FileSender itself and you can start to use it.

FileSender FAQ

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.

Sending notification to multiple recipients

Problem description: How to send notification in FileSender to multiple recipients about storing a file?

Solution: Separate the email addresses of recipients by comma.

Sending multiple files

Problem description How to send multiple files?

Solution: You can choose between two choices to achieve sending multiple files at once. One choice is to create an archive using WinZip, tar, etc. The second choice is to use a testing version of FileSender (filesender2.cesnet.cz). Because this is the testing version we can't assure the behavior of this instance. If you find a bug or strange behavior, so contact us at support(at)cesnet.cz.

FileSender requirement for your browser

Problem description What are the FileSender requirements on your browser?

Solution: Your browser must support HTML5 or Adobe Flash technology (Using Adobe Flash you can upload file sizes only up to 2GB).

Expiration time for data sent via FileSender

Problem description How long is the maximum file expiration period in FileSender?

Solution: Current version of FileSender allows to store data along one month period.

API and command line file upload

Description of the problem: Is it possible to upload files in a different way than via the web interface, i.e. directly from measuring or computing machines?

Solution: Yes, if the system has the ability to use the command line and python version 3, it is possible to use the offered script directly in the FileSender interface. You can find this script after logging in to FileSender under your user account (authentication via eduID) in the “My Profile” section and the “Python CLI Client” section, where you can download 2 files - the python script itself and the configuration containing the API key as well. which we upload to the path of our home directory ~/.filesender/filesender.py.ini . The script can be used without a configuration file, but at least the API-key and “User identification” (format abcdefghijklmnopqrstuvwxyz0123456789@einfra.cesnet.cz) must then be used as parameters on the command line. (this identifier can be found in the system Perun tab user - authentication - Login in EINFRAID-PERSISTENT)

Sample upload with downloaded and correctly placed configuration file:

python3 filesender.py -r abcdefghijklmnopqrstuvwxyz0123456789@einfra.cesnet.cz uploaded.file1 uploaded.file2

Sample upload using an API key:

python3 filesender.py -a 1234567890123456789012345678901234567890123456789012345678901234567890 -u abcdefghijklmnopqrstuvwxyz0123456789@einfra.cesnet.cz -r e-mail@recipient.com uploaded.file1 uploaded.file2
