SSIS FTP over explicit TLS/SSL Files Download
-
I have a package that generates an XML file that I need to send to one of our customers every night.
Their FTP server will only allow connetions using FTPeS (FTP Over Explicit TLS/SSL). Is there a way to get the FTP task in SSIS to perform this function? If not, does anyone have another suggestion on how to do this?
I have experimiented a little with the http://ftp.exe in windows but I cannot get it to create an SSL connection either.

Neither windows ftp nor the FTP task will do encrypted tunnels. Whether they be FTP/S or SFTP. You might be able to find a command line FTP/S tool but I am not aware of one. Keep in mind that FTP/S and SFTP are VERY different protocols. With FTP/S being most like standard FTP.

The standard FTP Task doesn't support FTPS. Neither the http://ftp.exe tool supports it. You have to use third-party tool. One of the options is CozyRoc SFTP Task. It supports both FTPS and SSH secure protocols and the setup dialog is very similar to the standard FTP Task dialog.

CoreFTPsupports Sftp and other secure ftp types, and can be scripted and. Called via a command line or Process.Start in. Net.
Ive got it in place for a regular batch process. You basically set up a PROFILE, which has the User and pass, then call coreftp and name which profile, so no passwords are visible in the script or batch or whatever.

If you post a question, make sure you include a CREATE TABLE... statement and INSERT INTO... statement into that table to give the volunteers here representative data. with your description of the problem, we can provide a tested, verifiable solution to your question! asking the question the right way gets you a tested answer the fastest way possible! -
Thanks for everyone's responses. I am not sure what to do yet, but I know what direction I can go in not (and more importantly, what I can stop looking at)

Thank you for the tip.
In the end what I ended up doing was using CoreFTP LE to get it done. I did use the Execute Process Task for running it with the appropriate arguments. The suggested way of running it was with a profile already created however the profile is specific to the login.
I am not sure how CoreFTP handled the certificate acceptance, I accepted the certificate when I first set up the profile. I do not know if it would have worked without that acceptance.
