I wanted to check out a folder from the KDE Subversion repository as a git repository, so I used the git-svn tool to accomplish that. These were the steps I followed:

1. git svn init \
   https://bram@svn.kde.org/home/kde/trunk/extragear/utils/rsibreak
2. git svn fetch

But that didn't work out, I got the following error:

By default, when you start the SVN server, svnserve, it listens on a port via the IPv6 protocol. This means you cannot connect to the server when approaching it with a xxx.xxx.xxx.xxx (IPv4) address.

You can solve this by adding the following parameter to the svnserve call:

You should supply this in the configuration file taking care of starting svnserve.
