Using lftp on Redhat to Mainframe

[sperr22]

I need to set up an ftp connection from a Redhat server to our Mainframe. We are using ftp today but we are no longer allowing ftp on internal transfers and need to set up an TLS/SSL connection. Can someone point in the right direction on how to either configure LFTP(compiling, options, etc...) to do this or is there another tool that would be better to use (stunnel, vsftp, etc...)

You should be able to use stunnel to set up a ssl link to the mainframe.
You shouldn't need to change your client ftp program, though you will want
to use a private port on your local host for the connection, since the way
that stunnel works is for your client to connect to localhost:port#. In the
stunnel configuration file you put in /etc/stunnel, call it
/etc/stunnel/mainframe.conf, you will specify the mainframe system address:port#
used by its ftp server. So, you should be able to use "lftp localhost:port#",
or "lftp -p port# localhost", or one of those constructs with the ftp OPEN
command.

I do use stunnel, but not with ftp, so I would have to experiment some to verify its operation, but you should find it too difficult to do, I would hope. Sorry about having to put the stuff above inside a CODE block, but otherwise some of the examples got replaced with smileys!

From all the reading I have done on Stunnel, everyone suggests not to use it with FTP. Even stunnel.org recommends against it. I uess I will continue looking for other means. Thanks
