=head1 RemoteShellExp
|
||||
Uses perl Expect to set up ssh passwordless login on the input node list
|
||||
Called from xdsh <nodelist> -K command
|
||||
It works for node and devices ( such as QLogic Switch).
|
||||
See man xdsh.
|
||||
It works for root and non-root userids.
|
||||
|
||||
Environment Variables input to drive the setup:
|
||||
|
||||
DSH_REMOTE_CMD set to path to remote shell (ssh)
|
||||
root password must agree on all the nodes
|
||||
|
||||
XCAT_ROOT set to root of xCAT install
|
||||
|
||||
DSH_REMOTE_PASSWORD - to_user password for -s option required to sendkeys)
|
||||
Note this is obtained in the xdsh client frontend.
|
||||
|
||||
SSH_SETUP_COMMAND - Command to be sent to the IB switch to setup SSH.
|
||||
|
||||
DSH_FROM_USERID_HOME - The home directory of the userid from
|
||||
where the ssh keys will be obtained
|
||||
to send
|
||||
|
||||
DSH_FROM_USERID - The userid from where the ssh keys will be obtained
|
||||
to send
|
||||
to the node, or generated and then obtained to send to the
|
||||
node.
|
||||
DSH_TO_USERID - The userid on the node where the ssh keys will be updated.
|
||||
DSH_ENABLE_SSH - Node to node root passwordless ssh will be setup.
|
||||
|
||||
|
||||
Usage: remoteshell.expect
|
||||
[-t node list] test ssh connection to the node
|
||||
[-k] Generates the ssh keys needed , for the user on the MN.
|
||||
[-s node list] copies the ssh keys to the nodes
|
||||
|
||||
exit 0 - good
|
||||
exit 1 - abort
|
||||
exit 2 - usage error
|
||||
|
||||
Examples:
|
||||
$rc=xCAT::RemoteShellExp->remoteshellexp("k",$callback,$remoteshellcmd);
