=head1 NAME
|
|
|
|
B<makeknownhosts> - Make a known_hosts file under $ROOTHOME/.ssh for input noderange.
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
B<makeknownhosts> [I<noderange>]
|
|
|
|
B<makeknownhosts> {B<-h>|B<--help>}
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
B<makeknownhosts> builds a known_hosts file in the $ROOTHOME/.ssh directory for all nodes from the input noderange. The known_hosts file is built from the
|
|
shared ssh host key that xCAT distributes to the nodes.
|
|
To build the key for a node, you are only required to have the node in the database and name resolution working for the node. You do not have to be able to access the node.
|
|
Having this file will avoid the ssh warning when nodes are automatically added to the known_hosts file. The file should be distributed using xdcp to all the nodes, if you want node to node communication not to display the warning.
