[GiNaC-list] Access denied when cloning git repository

Hello, I am trying the clone the GiNaC and CLN git repositories. Both commands git clone git://www.ginac.de/cln.git and git clone git://www.ginac.de/ginac.git fail with the following error message: fatal: remote error: access denied or repository not exported: /ginac.git Am I using a wrong command or are the git repositories currently not available? Best regards, Matthias
