What are my options for encrypted file transfers between Solaris and

secure FTP. I'm suspecting that the Solaris results will be the same.
I'd rather not use z/Linux as a relay between Solaris and VM, but if
it's the only option, I will. The other client that needs to work is
F-Secure FTP in Windows.
sftp is not what VM gives you.
sftp is an ftp-like command stream layered atop the ssh protocol.
There is no native VM implementation of this, although we did produce
an FTP-to-sftp broker a few years ago that did the trick (admittedly,
transfers from the VM-hosted Linux guest to the VM system itself were
in the clear, but all traffic on the actual wire outside the VM box
were encrypted).
I've had pretty good luck with a product called "Secure FTP" from
Glub Tech. http://www.glub.com/products/secureftp/
I know it works with the z/VM 5.3 SSLSERV code in negotiated TLS
mode. I don't remember offhand whether it works with 5.2 in implicit
mode; I suspect I tested it, but I don't remember the results. There
certainly *are* a few FTP clients for Linux that *can* cope with
implicit SSL as provided by SSLSERV for the z/VM TCP/IP stack, and
they should be easily buildable for Solaris.
Since Secure FTP is written in Java, it should work fine on Solaris.
I don't know about F-Secure FTP. I have not tested it.
