Versioning system| Git.UP

Problems after migration from 10.12.2021

  •     Warning about changed host key

When cloning, pushing, etc. a warning is displayed on the CLI: "POSSIBLE DNS SPOOFING DETECTED - The ECDSA host key for has changed". This is correct because the IP behind the service has changed. To fix this, do the following:

Git Bash:

ssh-keygen -R


ssh-keygen -f "/home/$user/.ssh/known_hosts" -R ""


  •     Account blocked

You cannot fix this problem by yourself. Please send us an email to zim-serviceuni-potsdamde.

The problem is caused during the login procedure. We are currently working on fixing this. Please do not use the LDAP login mask.


  •     SSH key is not accepted

If you use Git.UP via SSH with an SSH key, it may happen that this key is rejected. In this case please set your public key again in your Git.UP profile settings. Afterwards it should be accepted again.


  •     Login via CLI does not work

Please create a new access token according to the following instructions and use it for login instead of the password.

With Git.UP, a versioning system, the ZIM offers a service that allows distributed teams to work together on software projects. It is based on the version management system Git and supplements it with intuitive project management and integrated task management.

Members of other universities from the DFN-AAI Federation can also collaborate on projects hosted here.

Git allows local version control even without a central server. Changes can be transferred to a server (such as Git.UP) at a later time - either as a private backup copy or to share the project with others.

Data is synchronised via HTTPS and SSH (from the campus network) between the local repository and a repository on another machine.

This service provides management of versions of:

  • source code (C, C++, php, etc.)
  • digital documents (PDF, Office files, TeX, etc.)
  • Configuration files (.ini, .dat, etc.).

You can:

  • create source code repositories
  • version source code files, etc.
  • Manage source code branches
