Jamis or anyone else, if you have any thoughts/input please share.

CODE:

def login_to_server
Net::SSH.start(self.ip_address, self.username, :password =>
self.password, :paranoid => false)
end

def get_tty(ssh)
puts "*******SSH: #{ssh}"
channel = ssh.open_channel
puts "*******CHANNEL: #{channel}"
return channel.request_pty

end

def run_command(ssh, command)
ssh.exec!(command)
end
=============================================================================
