Any command line sftp client programs that can resume?

[Ant]

Hello.

Is there a sftp command line program that can resume downloads and
uploads in Linux? Sftp doesn't seem to do it even with full completed
files to skip. I love ncftp and lftp, but they don't do security.

Thank you in advance. :)

What security are you expecting? My Debian's lftp fully supports SFTP.

*I* use rsync over ssh with the rsync --partial option (or -P) for this
functionallity.

My experience "shows" that rsync over ssh is good solution too, but in
case syncing files across unstable and slow WAN connection(s) there are
sometimes problems with it, I didn't investigate reasons, I just kill
rsync process and try again day later - works fine for me for backup
purposes of big directory structures which contain hundreds of GiB,
millions of files/directories and very deep/long directory structure.

For extreme problematic connections (S)FTP/(S) works a way better for me.

Try psftp’s reget command.

Yes.

“PuTTY is a free implementation of Telnet and SSH for Windows and Unix
platforms”.

Interesting. I didn't know it ported to UNIX. Nice. I use it in Windows.
Now, if it could add Zmodem file transfer features like SecureCRT. ;)

Thanks. Hmm, PuTTY's psftp is not good as ncftp and others:
1. Slower.
2. (M)get can't autodetect to resume downloads or not.
3. Autotab completes do not work (adds tabs/spaces).
4. No original file dates and times.
5. Reget doesn't seem to like downloading more than one files like this

reget *

/home/test/downloads*: open for read: no such file or directory

Maybe I missed something from my quick usages?

rsync ? Much better than sftp. Also depends on what you want to
download. If it is from a public server, why in the world do you want
security? If not, get the other side to install rsync.

Recompile your lftp with 'configure --with-openssl' and read about
options ftp:ssl in man lftp.

I have no idea if my updated 64-bit Debian stable's provided lftp
package has it or not, but I tried:

$ lftp ftp:ssl-protect-data <a remote FTP server's address>
lftp: ssl-protect-data: no such tcp service

Am I doing this wrong as a newbie? FYI:

$ lftp -v
