Replacing FTP with SFTP

[Admiral Huddy]

Currently, we have various processes that FTP our backups to our DR host using FTP. These are done via scheduled FTP scripts from our iSeries.

We wish to secure these FTP processes with an encryption method and i've been asked to look at SFTP. However, I'm lead to believe that SFTP is not FTP over SHH. I'm not sure what this actually means so I'm a little confused.?

Does this means we'll have to re-engineer our FTP scripts? Or is it just a case of pointing the conection through a different port i.e. 22.

Any help would be greatly appreciated.

Unless your FTP scripts are complex then there isn't going to be a huge amount of re-engineering requried. PUT is still PUT etc.

The logon is probably the biggest change - I assume you'll be going to SSH key exchange rather than ID/Password authentication.

EDIT: Just noticed your comment about pointing the connection to port 22 - you'll need to replace your FTP client & server with an SFTP client & server.

Ok I think I half have you. So when i run the script, what dicates it's SFTP over FTP?

The FTp is started on an iSeries

STRTCPFTP host which refers to a script to run

the script looks like ftis so the ftp x x x isn't atcually used.

 quit

edit.. ok.. i've just found out that sftp isn't supported on the our current OS release.
