Secure Shell (ssh) is the preferred method for accessing the HP XC system. Typically, a user accesses the HP XC system using ssh to get a login shell or to execute commands.
The ssh service also enables file transfer using the scp or sftp commands over the same port as ssh. The typical r* UNIX® commands (rsh, rcp, rlogin) are not on an HP XC system by default because of their inherent insecurity. The ssh command transfers all login and password information in an encrypted form instead of in the plain text form used by the r* UNIX telnet and ftp commands.
For security purposes, use the ssh command instead of these other, much less secure alternatives.
To use ssh without password prompting with a user account, you must set up ssh authentication keys. For details, see Configuring the ssh Keys for a User.
