Hi, I know this will be a dummy question but I cannot find how to solve this trying in several ways but none of them work. The issue is that when I try to clone I get:

May 24 09:25:39 jooga git-daemon: [14724] '/home/repo/git/xscreensaver.git': not in whitelist

My git-daemon conf is this:
8< -----
service git
{
        disable         = no
        type            = UNLISTED
        socket_type     = stream
        protocol        = tcp
        user            = nobody
        wait            = no
        server          = /usr/bin/git-daemon
        server_args     = --inetd --export-all
}
8< -----
I've tried with `--inetd --export-all /home/repo/git', `--inetd
- --export-all --base-path=/home/repo/git /home/repo/git', with
interpolated to with a symlink but nothing works, I'm trying with:
git clone git://repo.ghostbar.ath.cx/home/repo/git/xscreensaver.git noseless
Anyway, cloning trough http worked but is not what I want :)
Any toughs?
Regards.

Specifying a symlinked path won't work. git-daemon (being of the one-shot-fork school of programs) simply does a chdir() to the requested directory and then getcwd(), which will never consider symlinks. This is a security feature, since directory recursion attacks will never ever work.

When you specify base-path, you tell git-daemon to prepend the base-path to the directory the user requests.

Start git-daemon like this:
git-daemon --base-path=/home/repo/git --export-all
then do
git clone git://repo.ghostbar.ath.cx/xscreensaver.git

and it should work, assuming /home/repo/git/xscreensaver.git has no symlinks in it.
