I echo your lack of understanding. Sometimes, "if it ain't broke ... don't
fix it" applies and if you *are* going to muck with it, create an
enhancement and leave the, working, original alone.

I've been using 1.2.27 (non-com), w/ the 2.0.13 patch, for quite a while
now. It works fine, but I'd really like to have a Win32 version of both. I
haven't gone to OpenSSH because of issues like what we're talking about here
(however, I use OpenSSL quite a bit). I also don't understand the
fascination folks have for FTP. Anything that uses non-deterministic
dynamically reassigned ports is fundimentally insecurable. Full
authentication can only be accomplished when both sides of the connection
are fully deterministic. In short, sftp ain't... FTP must die. If you want
secure files distro, use https. If you want secure file uploads, scp does
the job nicely, or a Java uploader, under https. Getting the SSH/FTP(sftp)
kludge to work only weakens SSH.
