=Examples=

==One==

<pre>
require 'net/ssh/multi'

Net::SSH::Multi.start do |session|
# access servers via a gateway
session.via 'gateway', 'gateway-user'

# define the servers we want to use
session.use 'user1@host1'
session.use 'user2@host2'

# define servers in groups for more granular access
session.group :app do
session.use 'user@app1'
session.use 'user@app2'
end

# execute commands on all servers
session.exec "uptime"

# execute commands on a subset of servers
session.with(:app).exec "hostname"

# run the aggregated event loop
session.loop
end
</pre>

==Two==

<pre>
require 'rubygems'
require 'net/ssh'

username = "yourusername"
hostnames = ["node01","node02"]
script = "date;uptime;"

hostnames.each {|hostname|
Net::SSH.start( hostname, username ) do |session|
session.open_channel do |channel|
channel.on_data { |chan,output|
puts "#{output.inspect}"
}
channel.on_extended_data { |chan, type, output|
print output
}
channel.exec script
end

session.loop
end
