Serve-U has an FTP server that does both types of secure FTP (ftp over ssh and 
ftp of ssl). The cost for a single server is fairly reasonable, if memory 
serves.

I know of no free (in either sense) secure FTP server for windows.

Can you turn the sense of the transfers around? In other words, can you have 
the windows machine poll the unix machine for new files to transfer? If so, you 
could use the win32 version of scp (putty's pscp) and have it logging into the 
unix box periodicly to check for new files to download and process.

One option would be to set up IIS on the windows box with a small Perl CGI 
script to "catch" the file that you post via SSL using the LWP perl module on 
the unix side. 

Another option would be to install Samba on the unix box and use smbmount to 
mount a windows share to the unix box (Samba handles encrypted passwords). Or, 
use Services for Unix on the windows side to create a shared area via NFS. 
You'd then have to encrypt the actual data file on the unix side and decrypt it 
on the windows side. If you only care about not sending passwords plaintext, 
skip the encryption/decryption steps.

Hi Tobias,

Thanks for the information. The problem we've run into using sftp is that
we need to have an sftp server running on the target machine. Management
are
keen on saving money, but also have the fixated paradigm that server
products
have to be cost money, i.e., have some company behind them for support.
There
is allowance made for in-house code (a la Perl), so if there is a way of
using windows natively for file-transfer operations by way of Perl code,
that would be optimal.

best,

 /dennis
