Meanwhile I searched some more... This has turned out to be the 2nd
problem, the first one is wheter svnserver supports IPv6 adresses or
not. Meanwhile, I suspect ist does not and if that's true, I must
use apache instead of svnserve anyway. I found some descriptions about
how to chroot apache2 in the net.

My intention was to keep a hacker as restricted as possible, if he/she
manages to get into the system via svnserve. Ssh would require to create
user accounts and I don't know about apache yet.

Being rather new to all this, it seemed to me that svnserve could be
safer than apache, because it serves exactly one thing, access to a
subversion repository. And the setup is simpler. I also liked the
authentication mechanisms better. But meanwhile I'm not so convinced
anymore... maybe apache is safer...

Exactly. That's what I'm concerned about. And yes, if apache2 will be used
as a server for subversion, it will be chrooted.
I was hoping that someone on the mailing list has experience with chrooting
svnserve and can give me a few hints.

Anyway, thank you very much, Chris

Have fun
