SSH-capable FTP servers?

[hw_tph]

We currently run multiple FTP servers on Windows and Linux, most of them internal to the company but some are accessible from the Internet.

I would like to migrate the ones that do have a public interface to some sort of SSL-capable FTP server (and perhaps later move all our FTP servers to the new software).

What choices do I have? As far as I know RaidenFTPd and Serve-U support SSL-FTP on Windows, but those are not very compelling to me. Also, is there *any* Linux-based daemon that can do this?

We are currently using a mix of ProFTPd and WUFTPd on Linux and IIS on Windows (NT/2000). Is there a smooth upgrade path for any of these to a SSL-capable daemon?

Thanks for any input.

There's a patch to add support for ProFTPd

glFTPd (http://www.glftpd.com) is capable :D It's a highly configurable free *nix daemon. ;)
