SYNOPSIS

DESCRIPTION

14       kdumpctl is used to check or control the kdump service.  In most cases,
15       you should use systemctl  to  start  /  stop  /  enable  kdump  service
16       instead. However, kdumpctl provides more details for debug and a helper
17       to setup ssh key authentication.
