Re: ssl ftp

[Scott Klement <sk@xxxxxxxxxxxxxxxx>]

Hi Diane,

FTPAPI is not capable of accessing web servers (whether SSL or not), 
it's only capable of accessing FTP servers.  It's sister project, 
HTTPAPI is for accessing web servers.

Do you mean that you will be adding SSL to your FTP server?   If so, you 
have the option to allow only SSL connections, or to allow both SSL and 
non-SSL connections. Since FTPAPI doesn't support SSL, you'll need to 
run it through a non-SSL connection.

Note that I do not recommend SSL FTP.  It's a real bear to get SSL FTP 
to work through the ubiquitous NAT gateways out there, and this makes 
SSL FTP a real headache.  If you have any say in the matter (...and I 
realize that you may not...) consider using sftp (the FTP-like interface 
to SSH) instead of SSL FTP.  It works much better, IMHO.

On the other hand, since you were talking about web sites, you might 
actually mean HTTPAPI instead of FTPAPI.   HTTPAPI supports SSL, and has 
supported it since the start.  SSL was originally designed to work with 
the HTTP protocol, so they play very nicely together.

If you must use SSL FTP, however...   IBM's FTP client (the one that 
comes with i5/OS) does support SSL starting in... err, I can't remember 
if it's V5R2 or V5R3 that's the first release to support it.  But, it's 
supported...

You could, of course, add SSL support to FTPAPI. I haven't done so 
because I haven't needed the support myself. Remember that FTPAPI is an 
open source project.

Craig Strong did write some SSL enhancements to FTPAPI at one time, but 
I couldn't include them because they broke other things in FTPAPI's 
behavior.  You can read about them, and download Craig's code if you 
want it, from the following link:
