lftp
lftp is a sophisticated command line based file transfer program. Supported protocols include FTP, HTTP, SFTP, and FISH. It has a multithreaded design allowing you to issue and execute multiple commands simultaneously or in the background. It also features mirroring capabilities and will reconnect and continue transfers in the event of a disconnection. Also, if you quit the program while transfers are still in progress, it will switch to nohup mode and finish the transfers in the background. Additional protocols supported: FTP over HTTP proxy, HTTPS and FTP over SSL, BitTorrent protocol. IPv6 is fully supported. There are lots of tunable parameters, including rate limitation, number of connections limitation and more.

Found a way around this, visit the vsftpd project to see my comments.
Also made some other discoveries which I hope help someone else.
lftp requires both ssl:cert-file and ssl:key-file in order to deliver it's certificate upon request.
Also, when using ssl:verify-certificate, it reuires nsCertType = server as a part of the server's certificate.
Secure ftp
Works nice, thanks. I do have a question. When using ssl:verify-certificate what is required for the certificate to be signed by a known Certificate Authority? I'm getting "Fatal: self-signed certificate". This may be a vsftpd problem because the only certificate I found which works is created by 'openssl req -new -x509 -nodes \
-out vsftpd.pem -keyout vsftpd.pem'. However, I'm hoping to find a way around this. Thanks for any help.
Best ftp client ever
Transferring the power of the shell to FTP. Couldn't get much better.
