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 al
lows file transfer usi ng the scp or sftp commands over the same
port as ssh.Thetypic
al r* UNIX commands (rsh, rcp, rlogin)arenotonanHPXC
system by default be
cause of their inherent insecurity. The ssh command transfers all login
and password infor
mation in an encrypted f orm instead of the plain text form used by the r*
UNIX comm ands, tel
net and ftp.
For security purposes, use the ssh comm and instead of these other, much less secure
alternatives.

authentication keys. See the HP XC System Software User’s Guide or the ssh
