|
|
|
|
=head1 SYNOPSIS
|
|
|
|
B<makeknownhosts> I<noderange> [B<-r>|B<--remove>] [B<-V>|B<--verbose>]
|
|
|
|
B<makeknownhosts> {B<-h>|B<--help>}
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
B<makeknownhosts> Replaces or removes in the known_hosts file in the $ROOTHOME/.ssh directory, the enties for the nodes from the noderange input to the command.
|
|
The known_hosts file entry is built from the shared ssh host key that xCAT distributes to the installed nodes.
|
|
|
|
HMCs, AMM, switches, etc., where xCAT does not distribute the shared ssh host key, should not be put in the noderange.
|
|
|
|
To build the known_hosts entry 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 with correct entries, 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.
