I'd like to know if it's possible to initiate an FTP (with TLS) connection from the command line. I know that FTP is available from the command line, but I'm not sure how to enable TLS, if it's even available.
My goal is to write an Automator workflow that securely uploads the content of a chosen folder to an FTP server. I currently use a third-party action called "Upload to FTP", but I don't think it uses the TLS protocol.
15, Mac OS X (10.6.5)
If you're simply looking for secure file transfers and are not specifically seeking ftps (ftp over tls/ssl), then have a look at ssh (for interactive access) and sftp (for secure file transfers over ssh). Both ssh and sftp can be set up with certificates, and are securely encrypted. There are ftps clients around for Mac OS X (eg: FileZilla, Cyberduck), but command-line sftp is built in.
curl --ftp-ssl ...
Thanks! Scripting accomplished 🙂
curl --ftp-ssl
will attempt to connect via encryption - but it will silently revert to a non encrypted connection if it can not.
curl --ftp-ssl-reqd
might be a better choice: it will fail with an error message like
curl: (64) Requested SSL level failed
when it can not connect via SSL
Thanks for jumping in on our old thread. I didn't know about --ftp-ssl failing silently under some circumstances, so I've added -reqd as per your comment. Security is my priority, so I feel much better having added it. Thanks!
Maybe look into the the "scp" command.
