Any command line sftp client programs that can resume?

    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.

  4. *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.

    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

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

    Maybe I missed something from my quick usages?

  13. Isn't GnuTLS supposed to replace openssl bug-by-bug? :)
