What is git-daemon?

man git-daemon will tell you quite a bit (and yes, it is a built-in that comes with Git). Git daemon is run via git daemon (notice no hyphen).

However, you should take a look at Gitolite if you intend on hosting Git repositories on a server.

Further, why are you cloning a repository with the intention of having that cloned, and any pushes to it forwarded to the repo it was cloned from? Just clone from the original repository!
