We have pssh for parallel ssh on multiple remote hosts
We have Ansible that it uses ssh as well.
We have Salt which can make use of ssh for ad-hoc but it is designed to be configured with an agent.
We have Chef which has a bit of a learning curve but it is very powerful. It requires an agent in the remote hosts.
Thank for this reply Aia.
I looked at each of the options you posted and was not familiar with a few of the website apps you posted.
Thanks again.

knife-ssh
KNIFE-SSH(1) Chef Manual KNIFE-SSH(1)
NAME
knife-ssh - Run a command or interactive session on multiple remote hosts
SYNOPSIS
knife ssh QUERY COMMAND (options)
-a, --attribute ATTR
The attribute to use for opening the connection - default is fqdn
-C, --concurrency NUM
The number of concurrent connections
-m, --manual-list
QUERY is a space separated list of servers
-P, --ssh-password PASSWORD
The ssh password
-x, --ssh-user USERNAME
The ssh username
-i, --identity-file IDENTITY_FILE
The SSH identity file used for authentication
-p, --ssh-port PORT
The ssh port
--[no-]host-key-verify
Verify host key, enabled by default.
DESCRIPTION
The ssh sub-command opens an ssh session to each of the nodes in the search results of the QUERY. This sub-command requires that the
net-ssh-multi and highline Ruby libraries are installed. On Debian systems, these are the libnet-ssh-multi-ruby and libhighline-ruby pack-
ages. They can also be installed as RubyGems (net-ssh-multi and highline, respectively).
TERMINAL MULTIPLEXING AND TERMINAL TAB SUPPORT
knife ssh integrates with several terminal multiplexer programs to provide a more convenient means of managing multiple ssh sessions. When
the COMMAND option matches one of these, knife ssh will create multiple interactive ssh sessions running locally in the terminal multi-
plexer instead of invoking the command on the remote host.
The available multiplexers are:
interactive
A built-in multiplexer. interactive supports running commands on a subset of the connected hosts in parallel
screen(1)
Runs ssh interactively inside screen. ~/.screenrc will be sourced if it exists.
tmux(1)
Runs ssh interactively inside tmux.
macterm (Mac OS X only)
Opens a Terminal.app window and creates a tab for each ssh session. You must install the rb-appscript gem before you can use this
option.
