LFTP is an enhanced sftp client that allows faster parallel down and uploads as well as a more convenient interface


LFTP Documentation can be found here http://lftp.yar.ru/

Getting and installing

Most current Linux distributions offer lftp through their package management. However they carry mostly rather old versions which have annoying bugs.

We suggest to use at least lftp versions above 4.7.x. The web site [LFTP http://lftp.yar.ru/] offers source packages that enable you to compile the most recent version. Check the README and the INSTALL files in the documentation of lftp.

To install lftp using your distribution package management tool

 yum install lftp
 sudo apt-get install lftp


Log in with your archive account

 lftp -u <abc> sftp://archive-sftp.lsdf.kit.edu
 Password: <password>

Upload a local file (lfile) to the archive:

 lftp>put lfile

Upload, reverse mirror (-R), a local directory (ldir) to a remote directory (rdir) using 4 processes. Use the --continue (-c) option to allow the mirror operation to continue where it left off in case something happens (usefull if you archive thousands of files and directories).

 lftp>mirror -c -R --parallel=4 ldir rdir

Download a remote directory using 4 streams for every single file. (This improves download speeds for large files):

 lftp>mirror -c --use-pget-n=4 rdir ldir
