The repository in question is
http://chiselapp.com/user/andreas_kupries/repository/crimp/home

The user 'anonymous' has 'clone' capability.
Running
<pre>
(1) fossil clone http://chiselapp.com/user/andreas_kupries/repository/crimp/home x.fossil
</pre>
or even
<pre>
(2) fossil clone http://anonymous@chiselapp.com/user/andreas_kupries/repository/crimp/home x.fossil
</pre>

Returns the error message "Not authorized to clone".

Then I gave the user 'nobody' the capability to 'clone'.
Running (1) now hangs the client, the only output seen is

<pre>
                Bytes      Cards  Artifacts     Deltas
Sent:              53          1          0          0
waiting for server...
</pre>
until I kill the command via ^C

This last is why I made the ticket.

For the first problem I wonder what the user settings are for repositories where I can run the equivalent of (1) and have a successful clone ...
