I’m using cloud files from Rackspace to store files in cloud. I know how to use ftp client with cloud files, but I would like to use Secure File Transfer Program, sftp on the command line, a true SSH File Transfer Protocol client from the OpenSSH project for security and privacy concern. How do I install sftp-cloudfs under Linux or Unix like operating systems? You need to use the sftpcloudfs package. This is a SFTP interface to Rackspace Cloud Files and Open Stack Object Storage (Swift).
