Git works with http on my system to different repositories, but with http it fails with the error shown below:
is this my fault?

E:\>git clone http://git.eclipse.org/gitroot/jgit.git
Cloning into 'jgit'...
fatal: http://git.eclipse.org/gitroot/jgit.git/info/refs not found: did you run git update-server-info on the server?

the URL for http is http://git.eclipse.org/r/jgit/jgit. Try this URL instead.

Ciao

git.exe clone --progress -v "http://git.eclipse.org/r/jgit/jgit" "E:\jgit"

Cloning into 'E:\jgit'...
fatal: http://git.eclipse.org/r/jgit/jgit/info/refs not found: did you run git update-server-info on the server?

git did not exit cleanly (exit code 128) (1419 ms @ 08.01.2013 13:09:46)

no luck with http

BUT

with https

git.exe clone --progress -v "https://git.eclipse.org/r/jgit/jgit.git" "jgit"

How can I find which protocols a given git-repo-server supports?

back to my question: shall git be able to pass credentials for a git:// protocol?
- at current timme - in my mind - git does not pass http.proxy info if the protocol is git:// so that means that any git user sitting behind a firewall needs to talk to git-hub-server wich supports at least http to pass credentials and/or https.

Thanks for your help - but still waiting for a response to my question.

Read the documentation of the infrastructure you are connecting to and if this doesn't help ask the administrator of the git server you are trying to access. For git.eclipse.org/r the git server is a Gerrit code review server running behind Apache used as a reverse proxy, I think there is no direct way to get its configuration from the client side except reading documentation [1] or asking the admin.

I will ask the Eclipse webmaster to close or redirect access to http://git.eclipse.org/r in order to avoid that other users get confused like you were confused here.

git:// protocol doesn't support authentication and it's not HTTP but a highly optimized binary protocol [2].

Corporate IT shops often don't allow other protocols than HTTP / HTTPS to pass the firewall.

Usually the git protocol is only used for fetching git objects from public repositories and push over git:// protocol is blocked, since it's not supporting authentication so the server has no way to check the identity of the user trying to push changes.
