#----------------------------------------------------------------------
# This script controls a Net::OpenSSH session.
#
#It can authenticate a connection via password or SSH private key.
#
#It can connect via:
#   1) root login
#   2) user login, then su to root
#   3) user login, then sudo to root
#
#Additionally, existing connections may persist and be reused.
#
#Once connected, it can:
#   1) copy a file from/to local/remote
#   2) AS ROOT: execute an arbitrary command on the remote server
#
#Inputs:
#   key/value are read from STDIN as a hash,
#   serialized with Cpanel::AdminBin::Serializer::Dump()
#
#
#   Required arguments:
#       authuser    The user as which to identify during the SSH login.
#
#       host        The remote host.
#
#       ctl         "ssh" or (usually "scp", but anything defined will do)
#
#
#   Additional, optional arguments:
#       external_master             ctl_pass parameter for Net::OpenSSH
#                                   Required if die_on_pid is not given.
#
#       die_on_pid                  ID of a specific process for the SSH control process
#                                   to watch and self-destruct upon the end of that
#                                   process. Defaults to the script's process ID.
#
#       port                        passed to Net::OpenSSH
#
#       root_pass                   If authuser is "root", used to login;
#                                   otherwise, used to escalate privileges via su.
