Re: Somewhat corrupted repository: Berkeley DB Permissions errors on SVN 1.0.2

I think your ideas are very good solutions to the problem, but why not
just have an svnserve daemon running on the remote box that waits for
local connections? I agree with all of this; i certainly don't want
permissions to bork my database, i would certainly agree to having only
one user access the database. I already setup an svn user to do just
that :)

But why not use a method that already exists? The only reason i'm using
ssh is that its security is guaranteed by a much larger user base, and
i trust having its port open far more than svnserve -d's port (3970?).
If there was an svnserve daemon that could authenticate a local user
(and not open a remote port!), it would be very handy to many folks.

just my suggestion to what appears to be a big stopping point for a few
