3.4.30 Create and Modify the
authorized_keys
File Using the
xtcc-ssh-keys
Command
The
xtcc-ssh-keys
command creates and modifies the
authorized_keys
file for Rack Controllers (RCs)
and Dual Aries Network Card Controllers (dANCCs) on Urika-GX systems. Due to constraints on volatile memory
storage, it does not update the
authorized_keys
file for the Intelligent Subrack Control Boards (iSCBs). It must
be run as root.
The
xtcc-ssh-keys
command takes no options. When run, it invokes the user-selected text editor (specified by
the VISUAL or EDITOR environment variables and defaulting to vi) on a file maintained by Cray HSS. This file has
the format described in
sshd(8)
under the heading "
AUTHORIZED_KEYS FILE FORMAT
". Adding a public key
to this file permits a user authenticating using the corresponding private key to connect to the RCs and dANCCs
without using a password. Once the file has been written from within the editor, the changes will take effect on
booted controllers within one minute.
For more information, see the
xtcc-ssh-keys(8)
man page.
3.4.31 Change the Passwords of RC, dANCCs and iSCB using the
xtccpasswd
Command
The
xtccpasswd
command changes the password for all Rack Controllers (RCs), Dual Aries Network Card
Controllers (dANCCs), and Intelligent Subrack Control Boards (iSCBs) on Urika-GX systems. It must be run as
