‘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?
How do I create a host key file to use with my applications as I can not use system defined /etc/ssh/ssh_host_rsa_key for non-root account under Linux / Unix / Apple OS X / *BSD operating systems?
How do I install my SSH public key ~/.ssh/id_rsa.pub onto a remote Linux / UNIX server automatically from Linux workstation / Apple OS X laptop without using scp and/or copy & paste method?
Q. How do I change OpenSSH passphrase for one of my private keys under Linux?
