# What is c4science ?
C4 Science is a co-creation platform, curation and code sharing. This platform includes:
* Version management system
* Common authentication to all Swiss universities to local + external collaborators
* Social dimension (wikis, bug tracking, ...)
* Code test system (continuous integration)
# Is the data stored on a safe server within Switzerland?
We're using Switch Engines infrastructure in Lausanne Datacenter, and Zurich as backup. Data are strictly stored in Switzerland, and securely transit only within the SWITCH network.
# Who has access to my user data?
You can see [[ https://drive.switch.ch/index.php/s/aSUdxyXg3YUnSeA | section 9.1 of the SLAs ]].
# My repositories are hosted on git.epfl.ch. What happens to them?
Push will be deactivated at the end of the year. The service will stay read-only until the summer. After this, everything will be archived, and available on demand. It's recommended to migrate your repositories to c4science.
# So there is now way to include automatically epfl groups?
We will provide a script to import EPFL groups in a c4science Project. Hold on!
# I subscribed to the platform but do not have permission to create new repositories, what is happening?
If you belong to a Swiss University, you can create repositories, projects and wiki pages. You need to connect using the SwitchAAI authentication method, or you won't be able to create objects on c4science.
# I just want a simple Git repo: help!
[[ https://c4science.ch/w/c4science/simplerepo/ | here are the instructions ]]. Do not hesitate to create a [[https://c4science.ch/maniphest/task/edit/?policy.view=PHID-PLCY-qhob65lybi5itkipfvwb&policy.edit=PHID-PLCY-zom4pfmfqmxuosdjggpg&projectPHIDs=PHID-PROJ-itwdg3fgxutsrdnqjklb,PHID-PROJ-eovnjqphn4al2vpqklvn|bug report]] if you think something should be added/changed.
# How I can create a private repository that is nowhere visible and accessible?
The repositories created via [[ https://c4science.ch/w/c4science/simplerepo/ | these instructions ]] are by default only visible/accessible by the creator.
# I get a 403 error, what do I do?
If the error looks like this
`fatal: unable to access 'https://c4science.ch/diffusion/997/simplegitrepo.git/': The requested URL returned error: 403`
you probably have not set up a VCS password. Have a look [[https://c4science.ch/w/c4science/whatisvcs/ | here]].
# I don't understand what the policies (Visible/Editable/Pushable) are.
- //Visible// means that the object (repository, project,...) can be accessed in read mode.
- //Editable by// is the list of administrators (who can modify the object via the web interface)
- //Pushable by// is for repositories and is the list of entities who can push to the repo
# What are "dangerous changes"?
Here are several changes that are classified as dangerous by Phabricator:
- delete a remote branch
- rewriting history
An administrator of the repository can allow dangerous changes.
# I use c4science to manage projects within my lab. Staff changes often. How do I give rights to a group?
C4science is global to all Swissuniversites members, thus you have to create a group in c4science to be referenced to. To do this, create a new project (or subproject) with icon type "Group" and add the appropriate users to it.
# I need to store binary files, how do I do this?
Binary files, must not be hosted directly in a repository. GIT is not made for that. You can use GIT LFS (large file storage) for that, see https://c4science.ch/w/c4science/lfs/ your files will still be referenced in the repository, but hosted outside of it.
Quotas policies will be defined at the end of 2016. Usage is strictly monitored until then.
# I would like to display a wiki page as homepage for a project instead of the //Recent Activity// feed.
Unfortunately, not yet -- you can add elements to the menu, task list, or modify the project description, which appears on the project page.
# C4science only provides SSH links for SVN
HTTP access is only possible for Mercurial and GIT.
# Is there a way to access a private repository without SSH key?
You can [[ https://c4science.ch/w/c4science/whatisvcs/ | use VCS ]]. Unauthenticated access must use HTTP instead of SSH, your repository view policy must be set to Public.

# Permission Denied when using a DSA SSH key
DSA/DSS keys are obsolete and the SSH client prevents its usage by default on most platform. Our server accepts such keys, but you have to allow the client to send it by modifying your SSH configuration like so:
```
Host c4science.ch
PubkeyAcceptedKeyTypes +ssh-dss
```
It is advised that you create an RSA key instead, of a minimum size of 2048-bit.
# Permission denied using SSH
It's possible that your key have a non standard name the your SSH client cannot find. By default, the client will look for id_rsa, id_dsa files. If you customized your key name, please specify your key in the client configuration like so:
```
Host c4science.ch
IdentityFile /home/aubort/.ssh/id_rsa_phab
```
